CAR WASHING APPARATUS
Abstract
Nozzles mounted on inclined pipes project narrow, concentrated
streams of washing liquid against a car and the pipes are
oscillated so that the streams wash inclined, overlapping swaths on
the car. Two of the pipes are on the side and are drivingly
interconnected by a top pipe. The operations of the sprays in a
plurality of arches of the car wash are controlled by a coin
actuated timer which also sequentially lights a series of electric
lamps extending along one side of the car wash to pace a driver of
a car through the car wash.

Description
This invention relates to an improved car washing apparatus, and
more particularly to a new and improved coin-operated car washing
apparatus.
Car washing apparatus known hitherto have required a large number
of nozzles and high capacity hot water sources to adequately clean
the cars. To lessen the number of nozzles the sprays have been
widened and thinned to effect the coverage needed, but this greatly
decreases the cleaning efficiency of the sprays. It would be
desirable to provide a car washing apparatus having a small number
of nozzles with thick, narrow sprays and still effect the necessary
coverage.
There has been known coin-operated car washing apparatus in which a
driver of the car deposits a coin to start operation of the
apparatus, and then drives through the apparatus in accordance with
the actuation of a series of signal flags positioned along the path
of the car and actuated in timed relationship to the actuation of
washing and rinsing devices of the apparatus. Such signaling or
guiding system has occupied an excessive amount of space, is
excessively complex and expensive and has been unsatisfactory.
An object of the invention is to provide a new and improved car
washing apparatus.
Another object of the invention is to provide a new and improved
coin-operated car washing apparatus.
Another object of the invention is to provide a car washing
apparatus having complete, efficient coverage with a minimum number
of nozzles and a minimum capacity hot water source.
A further object of the invention is to provide a car washing
apparatus provided with a plurality of nozzles adapted to direct
thick, narrow sprays of soapy water and rinsing water against the
surface of a car to be cleaned, the nozzles being oscillated to
cover swaths on the car as the car is moving, with the swaths
parallel to each other and at angles relative to the direction of
movement of the car so that the swaths overlap one another as the
car moves.
Another object of the invention is to provide a car washing
apparatus in which a soaping arch has a single row of spaced
nozzles and a rinsing arch has a single row of nozzles staggered
relative to the nozzles of the soaping arch, the lower nozzles
preferably delivering heavier streams of water than the upper
nozzles.
A still further object of the invention is to provide a car washing
apparatus in which a soaping arch covers a car with soapy water
and, as the car moves through a rinsing arch, nozzles thereof are
directed toward and rearwardly of the car until all the soapy water
is flushed off the front and top of the car and then are reversed
to flush the rear portion of the car.
Yet another object of the invention is to provide a coin-operated
car washing apparatus in which the driver of an automobile places a
coin in a coin box and then follows a series of signal lamps
arranged in a row and lighted seriatim to keep abreast of the
lighted lamps, and washing and rinsing devices are actuated in
accordance with the position of the car as it is moved through the
car washing apparatus.
Yet another object of the invention is to provide a car washing
apparatus requiring only a single soaping arch and a single rinsing
arch, with a single row of nozzles being provided in each arch.
The invention provides car washing apparatus including a soaping
arch and a rinsing arch. Each arch includes a plurality of nozzles
mounted in a U-shaped row preferably canted relative to the
perpendicular to the direction in which a car is moved through the
nozzles, and each of the nozzles supplies a heavy, high velocity,
narrow spray of water to the car with the sprays preferably being
progressively heavier proceeding downwardly. The nozzles are
oscillated relative to the car as the car is moved therethrough so
as to spray swaths on the car which, when the row is canted, extend
angularly relative to the direction of movement of the car and
which overlap as the car is moved so that all parts of the surface
of the car are cleaned. Since the swaths overlap, the sprays need
not overlap and can be narrow and heavy to have high momentum and
cleaning efficiency. The car washing apparatus also preferably is
of the coin-operated type and includes a timing device which is
actuated by a coin-operated mechanism to light one after another of
a plurality of lamps positioned in a row extending along the path
which the car is driven, and which also actuates the spraying units
of a soaping or washing arch and a rinsing arch so as to
sequentially wash and rinse the car as it is moved in accordance
with the lights as the lights are turned on one after another.
Preferably each arch includes side rows of nozzles and a top row of
nozzles, and the row of nozzles of the soaping arch is so
oscillated as to be directed rearwardly relative to the advancement
of the car as the first half of the car travels to and past the
arch, and then the nozzles are oscillated in a range directed
generally forwardly relative to the car as the rear half of the car
is moved to and through the arch. Thus only a single row of nozzles
is required to both spray the front half of the car and the rear
half of the car. Preferably the nozzles of the rinsing arch are
staggered relative to those of the soaping arch so that the more
efficient central portions of the sprays from the nozzles of the
rinsing arch strike portions of the car not struck by the more
efficient central portions of the sprays from the nozzles of the
soaping arch. Also, the nozzles of the rinsing arch are oscillated
in a rearwardly directed range of oscillation until the rear
portion of the car is abrease of the nozzles so that all of the
soapy water on the top and side windows of the car is flushed off
to the rear and then, when the nozzles of the rinsing arch are
oscillated in a forwardly directed range of oscillation, as the
rear portion of the car passes through the rinsing arch, the
forwardly directed sprays from the rinsing arch nozzles will not
push the soapy water back onto the central and front portions of
the car. Only a small number of nozzles are required because of the
oscillation and the shift of the range of the nozzles, and only a
small capacity source of hot water is required to very adequately
supply the car washing apparatus.
A complete understanding of the invention may be obtained from the
following detailed description of a car washing apparatus forming a

Referring now in detail to the drawings, there is shown therein a
car washing apparatus forming a specific embodiment thereof
including a soaping or washing arch 20 (FIG. 1) and a rinsing arch
22 which serve to sequentially wash a car 23 and rinse the car as
the car is driven therethrough. The driver of the car drives the
car so that the lefthand wheels 24 thereof (FIG. 3) enter between
and travel along tubular guide rails 26 forming a guideway having a
flared entrance opening 28. At the start, the driver puts a coin in
a known coin box actuator 30 to start the car washing apparatus,
the coin box actuator 30 then starts a timed control mechanism or
programmer 31 which lights incandescent lamps 32 seriatim, starting
at the lefthand end of a light bar 34 and progressing on to the
exit end of the apparatus, the driver of the car keeping abreast of
the lights as they are turned on, and the programmer 31 operated by
the coin box 30 sequentially actuates the soaping arch 20 to spray
hot, soapy water onto the car in thick, high velocity streams as
the car passes through the arch 20, and to actuate the rinse wash
22 to spray thick, high velocity streams of hot rinsing water onto
the car as the car comes to and passes through the rinsing arch 22.
A roof 36 covers the car washing apparatus.
The arches 20 and 22, except that the arch 20 is supplied with hot,
soapy water while the arch 22 is supplied with hot, rinsing water,
are substantially identical in their construction and operation,
and only the arch 20 will be described in detail. The arch 20
includes a housing 38 having vertical paneled portions 40 and 42,
open at the inside, and a paneled horizontal top portion 44, open
at the bottom thereof. The housing 38 includes an integral
framework 46 (FIG. 9) and forms an attractive enclosure. Side spray
pipes 50 and 52 carry nozzles 53 to 58 thereon, and are mounted in
radial and thrust bearings 59 and 60 and 61 and 62, respectively,
the radial and thrust bearings being supported by the frame 46. As
best illustrated in FIG. 10, the side spray pipes 50 and 52 are
mounted in parallel vertical planes but are canted relative to the
vertical as illustrated by the pipe 50 in FIG. 11, the pipes 50 and
52 being canted equally and in opposite directions from the
vertical. The pipes 50 and 52 are preferably canted at an angle of
about 15.degree. relative to the vertical.
A top spray pipe 70 (FIG. 10) is mounted rotatably in bearings 72
carried by the frame 46, and has pinned thereto bevel gears 74 and
76 which mesh with bevel gears 78 and 80, respectively, which are
pinned to the pipes 50 and 52, respectively. Both ends of each of
the pipes 50, 52 and 72 are plugged so that no water can pass
therefrom. Flexible hoses 82, 84 and 88 and centrally located stub
pipes 87 connect the pipes 50, 52 and 70, respectively, to a
manifold pipe 88 connected to a solenoid controlled valve 90 and a
filter 92 (FIG. 8) connected by a pipe 94 to a T-coupling 96
connected to a hot water pipe 98 and to a concentrated soapy water
pipe 100, the hot water pipe 98 being connected by known check
valve 102 to a hot water supply pipe 104 leading to a source of hot
water under pressure of a known boiler or supply plant unit 105
which also supplies hot, concentrated soapy water to the pipe 100
at the desired rate relative to that of the hot water supplied.
Each of the nozzles 53 to 58 (FIG. 9) delivers a thick or heavy,
fan-like spray or stream 106 in a vertical plane, the stream being
of high velocity and impinging on the car 23 with high
momentum.
The nozzles 53 to 58 are positioned about one foot from the sides
and top of the car. Since the lower portions of the car usually are
the dirtiest and the car becomes cleaner processing upwardly, the
nozzles 55 and 58 produce the heaviest sprays with the narrowest
angle of the fan-shaped sprays, this angle preferably being about
15.degree., the sprays from the nozzles 54 and 57 are the next
heaviest and with the next narrowest angle, preferably about
25.degree., and the sprays from the upper nozzles 53 and 56 are the
least heavy and the largest angle, preferably about 40.degree.. The
sprays from the nozzles 53 to 58 being progressively heavier
proceeding downwardly, the scrubbing action is progressively more
intense proceeding downwardly along the sides of the car.
The pipes 50, 52 and 70 are each continuously oscillated through
ranges of about 60.degree. as the car 110 is moved to the arch 22
and therethrough. The oscillations are effected by an arm 112 (FIG.
11) keyed to the pipe 70 and the bevel gear 74 and connected by a
link 114 mounted on a crank member 116 driven through a reduction
gear 118 driven by an electric motor 120. The oscillation
preferably is at a rate of about 79 oscillations per minute. The
electric motor 120 is mounted on a plate 122 hinged at its top end
by a pintle 124 carried by a bracket 126 secured to the frame 46 of
the arch. The plate 122 is pivoted relative to the frame 46 to
shift the ranges of oscillation of the pipes 50, 52 and 70, and the
position of the plate 122 relative to the frame 46 is controlled by
a bell crank lever 130 mounted pivotally on a bracket 132 and
driven by a water driven cylinder 134 controlled by a solenoid
operated three-way valve 135 (FIG. 8). When the car 23 is
approaching the arch 20 and until it has passed halfway through the
arch 20, the plate 122 is in the raised, full line position thereof
shown in FIG. 11 in which the nozzles 53 to 58 and nozzles 140,
141, 142 and 143 (FIG. 10) carried by and supplied with soapy water
by the pipe 70, are moved through a range directed generally
rearwardly relative to the travel of the car and such that the
fan-like streams from the nozzles are directed from 30.degree.
relative to the direction of movement of the car 23 to 90.degree.
relative to the direction of the car 110 through the arch. Each of
the nozzles 140 and 143 emits a spray 106 subtending an angle of
about 30.degree.. While the rear half of the car is passing through
the arch and for a short time thereafter, the cylinder device 134
holds the plate 122 in its lower, broken-line position thereof
shown in FIG. 11 in which the nozzles 53 to 58 and 140 to 143 are
oscillated in a range from one extreme in which the streams are
perpendicular to the side of the car to a second extreme in which
the streams are directed forwardly relative to the car at an angle
of 30.degree. relative to the direction of movement of the car. The
angles of the fan-like streams or sprays 106 are quite narrow and
such that the streams themselves never overlap at any one instant,
as illustrated best in FIGS. 12 to 17. However, the nozzles are
oscillated to oscillate the streams to cover zig-zag swaths, one
stroke of the swaths being shown approximately at 150 (FIG. 12).
The swaths are canted or sloped relative to the direction of
movement of the car and the car moves slowly through the arch,
about 16.8 feet per minute being preferred. Since the nozzles are
oscillated relatively rapidly, as compared to this movement of the
car and the swaths are canted, the swaths 150 overlap each other
and all portions of the side of the car are covered by the swaths.
Similarly, the swaths from the nozzles 140 to 143 overlap each
other as do also the swaths from the nozzles 56 to 58. All portions
of the forwardly facing surfaces of the car of the half of the car
adjacent the pipe 50 also are covered by the sprays as these
portions of the car approach the arch 20. By having the relatively
narrow angle sprays which do not themselves overlap, the streams
may be maintained as heavy, thick, high volume, high velocity, high
momentum streams which serve to efficiently scrub the car while
using a minimum of water, and by having the swaths canted so that
the swaths from adjacent sprays overlap so that each portion of the
car is covered by the sprays or streams, the entire car is scrubbed
with the heavy, high velocity streams of hot, soapy water and is
very effectively cleaned, while a minimum number of nozzles is used
and a minimum capacity of the plant 105 is required.
As the car 110 approaches the arch 20, the valve 90 (FIG. 8) is
opened and hot, soapy water under a high pressure is supplied to
the pipes 50, 52 and 70 (FIG. 9) and the motor 120 is turned on.
The cylinder device 134 is extended by the water under pressure
supplied thereto to hold the plate 122 in its full line position as
viewed in FIG. 11, which is the front half or approach position in
which the nozzles of the arch 20 are directed in a range varying
from one extreme of about 60.degree. in a rearward direction
relative to the travel of the car to a second extreme in which the
nozzles are perpendicular to the car, and the nozzles are
oscillated back and forth in this range. As the car approaches the
arch 20 the heavy, high velocity, high momentum streams of soapy
water are directed against the front and grill of the automobile,
and then, as the car continues to travel and the nozzles oscillate,
the nozzles direct the streams against the sides and the top of the
front half of the automobile. Then, as the car, which is moving in
accordance with the lighting of the lamps 32 with the driver
keeping approximately abreast of the lamp just lighted, comes to a
position in which it is centered longitudinally in the arch 20, the
cylinder device 134, by cutting off the supply of water under
pressure thereto, is actuated to move the plate 122 and the motor
120 to the broken line positions thereof shown in FIG. 11. This row
sets the range of oscillation of the nozzles 53 to 58 and 140 to
143 so that they are directed at their forward extremes about
60.degree. forwardly in the direction of advance of the car 23, and
the nozzles are oscillated between this forward extreme and a
rearward extreme in which the streams from the nozzles are directed
perpendicularly toward the car.
The forwardly directed oscillation range of the nozzles is
continued until after the car has passed out from under the arch 20
and the rear end of the car has been thoroughly scrubbed by the
heavy, high momentum streams of hot, soapy water. Then the valve 90
is turned off and the car travels to the rinsing arch 22 which is
substantially identical in construction and operation with the arch
20. The rinsing arch is supplied with only hot, clear, rinsing
water, and the rinsing water is applied thoroughly to the car as it
travels through the arch 22. The rinsing arch has nozzles 161 (FIG.
8) identical with but mounted by oscillated pipes 163 so staggered
relative to the nozzles 53 to 58 and 140 to 143 (FIG. 9) that the
central portions of the sprays of clear water from the rinsing arch
impinge on the car midway between the areas on the car on which the
central portions of the sprays of soapy water from the soaping arch
20 have impinged. Thus, the central portions of the sprays from the
nozzles 161, which are, of course, the heaviest and most efficient
portions of the sprays, scrub the areas which have been thoroughly
covered and soaked with soapy water but not so thoroughly scrubbed
by the central portions of the sprays from the soaping arch.
As the car approaches the rinsing arch 22 and for the first portion
of the travel of the car through the rinsing arch, the nozzles 161
(FIG. 8) of the arch 22 direct the heavy, high velocity, high
momentum streams of hot water over a range varying from 60.degree.
rearwardly to the direction of travel, to the perpendicular to the
car. During the last portion of the travel of the car through the
rinsing arch 22, the range of oscillation of the nozzles of the
arch 22 is changed to a range from perpendicular to the car at one
extreme to 60.degree. forwardly relative to the direction of
advancement of the car at the other extreme of the range. In order
to flush all the soapy water completely off the top and side
windows of the car, the nozzles 161 are oscillated in their
rearwardly directed range for substantially greater than one-half
of the travel of the car through the rinsing arch, preferably until
almost the entire top has passed the nozzles. Then the range of
oscillation of the nozzles is changed from rearward to forward, but
by this time all the soapy water has been flushed off the top and
side windows of the car so that the forwardly directed nozzles do
not carry any soapy water forwardly along the top and side
windows.
The programmer 31 (FIG. 7) operates to turn on the lamps 32 one
after another at time intervals, starting at the lefthand end lamp
32, as viewed in FIG. 7, and proceeding to the right along the
apparatus. The driver of the car drives the car so that he keeps
abreast of the most extreme lamp 32 that is lighted. The programmer
also sets the range of oscillation of the nozzles of the arch 20
and the supply of soapy water thereto while the car travels through
and beyond the arch 20, and then similarly controls the ranges of
oscillation of the nozzles of the arch 22 and the supply of water
thereto in synchronization with the lighting of the lamps as the
car approaches the arch 22, travels through the arch 22 and leaves
the arch 22. Prior to starting the cycle of the programmer 31, the
driver of the car drives the car to the coin box actuator 30 at
which a "stop" lamp 162 for lighting a "Stop" sign 172 is darkened
and a "go" lamp 175 is energized to illuminate a "Go" sign 176. The
driver stops, places a coin in the coin box actuator 30, which is
of a well known, commercially available type having a timer
therein, and this actuates the timer of the actuator 30, which
timer is adapted to run for about one-third of the cycle
encompassing the period of operation for one car to pass through
and be washed and rinsed by the car washing apparatus.
When the coin box actuator 30 is actuated, the timer thereof
immediately closes contacts 169 and 170. The closing of the
contacts 170 completes a circuit through contacts 186 to a
programmer motor 182 to start the motor 182. The contacts 169 start
the timer motor (not shown). At this time the motor 182 is
connected across powerline conductors 184 and 185 through contacts
186 which are permitted to be closed at this time by a cam 188
driven by shaft 189 driven by the motor 182. The cam 188 permits
the contacts 186 to be closed from before the start of the car
washing operation through about the first 10 percent of a complete
revolution of the shaft 189. The shaft 189 also has cams 190 to 214
which bring in contacts 220 to 244, except for the contacts 234, at
4 percent intervals of the revolution of the shaft, to light the
lamps 32 one after another, proceeding from left to right as viewed
in FIG. 7, the motor 182 driving the shaft 189 one complete
revolution for one cycle of the controller 31. The driver of the
car merely drives so that he is abreast of the latest lighted lamp
32 always.
Cams 251, 252, 253, 254, 255 and 256 also are provided on the shaft
189 and are driven thereby. The cams 251 to 256 control contacts
261 to 266, respectively, which are connected to a powerline
conductor 267 which is at the same voltage as the powerline
conductor 184. The contacts 261 are in series with the "Go" lamp
175 and are closed during the last fraction of 1 percent of one
cycle to the first 4 percent of the succeeding cycle. The contacts
262 are closed from 30 to 56 percent of the cycle, the contacts 263
are closed from 92 to 99 percent of the cycle, the contacts 264 are
closed from 58 to 99 percent of the cycle, and the contacts 266 are
closed from 4 to 99 percent of the cycle.
When the contacts 264 are closed, the motor 120 is energized and a
solenoid winding 270 is energized. The motor 120 oscillates the
pipes 50, 52 and 70 (FIG. 10) and when the solenoid winding 270 is
energized, it opens the valve 90. Thus, the first arch 20 runs from
4 to 58 percent of the cycle, with soapy water being sprayed and
the oscillation of the nozzles of the arch 20 being effected
through this portion of the cycle. The car travels halfway through
the arch 20 during the portion of the cycle from 4 to 30 percent of
the cycle, and during this portion of the cycle the nozzles are in
their rearwardly directed range of oscillation, the cylinder device
134 being supplied with the water under pressure to keep it
extended and to keep the plate 122 swung counterclockwise to its
extreme upward position, as shown in full lines in FIG. 11. Then,
at the end of the half of the movement of the car through the arch,
the contacts 262 are permitted by the cam 252 to close to energize
solenoid 274, which actuates the valve 135 (FIG. 10) to close the
supply of water off from the cylinder device 134 and drain the
cylinder device of water. This causes the cylinder device 134 to
contract and swing the bell crank lever 130 clockwise, as viewed in
FIG. 11, as the plate 122 with the motor 120 thereon bears against
the bellcrank lever 130 and moves to the lower positions thereof
shown in phantom lines in FIG. 11 to change the oscillation of the
nozzles 53 to 58 and 140 to 143 from the rearwardly directed range
to the forwardly directed range thereof.
After the car has been moved a short distance beyond the arch 20,
which is sufficient to thoroughly wash with the hot soapy water the
rear portion of the car, the contacts 262 and 264 are opened, to
de-energize the motor 120, de-energize the solenoid 270 and
de-energize the solenoid 274. The solenoid 270 closes the valve 90
to shut off soapy water from the source 106 (FIG. 8) and stops the
oscillation of the nozzles of the arch 30, and the de-energization
of the solenoid 274 opens the valve 135 (FIG. 8) to the cylinder
device 134. At this time the car is approaching the rinsing arch 22
and the cam 255 permits the contacts 265 to close, and they remain
closed 58 to 99 percent of the cycle. When the contacts 265 are
closed, a motor 280, which oscillates pipes 163 (FIG. 8) carrying
the nozzles 161 of the arch 22, is energized, the motor 280 being
identical in construction and operation to the operation and
construction of the motor 120. Closing of the contacts 265 also
energizes solenoid 282 to open valve 284 (FIG. 8) in the hot water
line 104 to supply the pipes 286 of the arch 22 with hot rinse
water, which is applied to the car by the nozzles 161 of the arch
22, the nozzles being directed rearwardly toward the front end of
the car as the car approaches and travels most of the way through
the arch 22 to scrub and flush all of the soapy water off the front
portions, all of the top and substantially all the sides of the
car.
After the car has passed somewhat over two-thirds of the way
through the arch 22, the contacts 263 are closed. Closing of the
contacts 286 causes energization of a time delay relay winding 290
which closes contacts 292 and opens contacts 294. Opening of the
contacts 294 opens one circuit to the lamp 175. Closure of the
contacts 292 causes energization of a relay winding 296 to close
contacts 298 and 300. Closing of the contacts 300 closes the
circuit to the "Stop" lamp 162. Closure of the contacts 298 closes
a circuit to the motor 280 in parallel to the contacts 265 in order
to drive the motor 280 for a short time after the completion of the
cycle, the time delay relay 290 delaying dropping out for a few
seconds after the motor 182 has stopped. When the contacts 292 are
closed, a solenoid 302 is energized, which so adjusts the position
of the motor 280 of the arch 22 that the oscillation of the spray
nozzles of the arch 22 are through a range of from perpendicular to
the car to 30.degree. to the line of travel of the car and in the
direction of travel of the car. Thus the rear half of the car is
rinsed by streams of rinse water having substantial portions of the
oscillation components in the same direction as the travel of the
car. The rinse spray is continued until the car has traveled out of
the arch 22 and the rear end of the car has been rinsed. At the end
of the cycle, or the 100 percent mark, the contacts 220 open to
stop the motor 182 at the zero position, the contacts 170 having
been opened previously by the timer of the coin box actuator 130
having timed out. The relays 290 and 296 also drop out a few
seconds later to de-energize the motor 280 and the solenoid 302.
The operation described above then may be repeated with another
car.
The programmer 31 is mounted in a cabinet 310 (FIG. 4) to which is
secured the coin box actuator 30. The motor 182 is mounted on a
panel 312, and drives the shaft 190 through gears 314 and 316. The
shaft 189 is journaled in bearings 318 carried by a frame 320
secured to the panel 312, and the contacts 186 and 220 to 244 and
261 to 266 are mounted on bars 322 and 324 of electrical insulating
material secured to the panel 312. A hinged cover 326 provides
access to the controller 160. The lamps 32 are supported in an
elongated sheet metal housing 328 having a translucent cover 330
facing the path of the car and enclosing the lamps 32 while making
light from them visible to the driver of the car. The housing 328
forms a continuation of the cabinet 312, and posts 331, 332 and 334
(FIG. 1) support the cabinet 312 and housing 328 along with the
arches 20 and 22, the housing fitting into notches 340 and 342 in
the arches 20 and 22, respectively. The housing 328 with the lamps
32 is positioned above the nozzles 53, 54 and 55 as illustrated in
FIG. 11 but sufficiently low as to be readily visible to the driver
of the car, preferably being at or slightly above the level of the
eyes of the driver.
The above-described car washing apparatus, by having only a small
number of nozzles which have the relatively narrow, fan-like sprays
106, requires only a small capacity pump and a small capacity
heater (not shown) of the known unit 105 forming the source of the
hot water and soapy water. Since the nozzles are few and the sprays
narrow, the sprays are kept thick, and high velocity is maintained
without using excess water, and this keeps the scrubbing or washing
ability of the sprays at a maximum. While the sprays do not
themselves intersect and provide complete coverage, they do by
their oscillation form the canted or inclined swaths to completely
cover the car as the car moves therepast. Since the rinsing nozzles
are staggered relative to the soaping nozzles, the entire car is
scrubbed hard by the central portions of the sprays from the
nozzles. Since the entire top of the car and the entire side
windows are flushed completely by rearwardly directed streams of
water from the nozzles of the rinsing arch before the nozzles are
shifted to their forward directions, no soapy water is pushed back
onto the side windows and front portions of the car.
It is to be understood that the above-described arrangements are
simply illustrative of the application of the principles of the
invention. Numerous other arrangements may be readily devised by
those skilled in the art which will embody the principles of the
invention and fall within the spirit and scope thereof.
