Description
BACKGROUND OF THE INVENTION
The present invention relates to improved machines for blowing
bubbles as well as to improved machines for providing water spray
for amusement. The invention has particular application for use
with bubble solution of the type used by children in blowing
bubbles.
It is well known that bubble machines have existed for some time
and are commercially available in a variety of embodiments. Prior
to applicant's co-pending application, and other applications by
applicant which have matured into U.S. patents, these bubble
machines have been of a type and geometry which provided no
resistance to spillage of liquid contents of the machine. In
addition, a variety of water toys have long existed that provide an
amusing spray of water as well actuate movement of cartoon
characters or cause the cartoon characters to spray water.
SUMMARY OF THE INVENTION
The present invention relates to an improved fluid powered bubble
machine having various impellers, fans, axles and gear working in
combination and wherein water from a source such as a garden hose
activates the bubble machine to generate a continuous stream of
bubbles. The machine can be used in combination with a sprinkler to
generate both a stream of bubbles from one end on the machine, and
a stream of water from the other end. In different embodiments of
the present invention, selective channeling of the sprinkler
portion of the bubble machine creates amusing and intermittent
streams of water. In some instances, only the bubble portion of the
machine is in use and the sole result is a pleasing, continuous
stream of bubbles. In other instances, only the sprinkler portion
of the machine is in use and the sole result is the generation of
streams of water useful for either water play or for watering the
lawn or other vegetation. In yet another embodiment, the water
sprinkling portion of the apparatus has a non-fluid powered bubble
machine, such as a battery powered bubble machine mounted on top.
In its ideal use, both the sprinkler and bubble portion of the
bubble machine are in use resulting in both a continuous stream of
bubbles and streams of water, thereby maximizing the pleasure
potential and utility of the invention.
In a preferred embodiment of the present invention, the fluid
powered bubble machine comprises an impeller housing which encloses
an impeller and which has a threaded opening for connection to a
standard garden hose. On one side wall of the housing is another
opening that forms a channel for providing fluid communication
between the inner cavity of the housing and a fluid tank. Water
flowing into the bubble machine from the garden hose or other water
source flows past the impeller causing the impeller to act as a
hydraulic motor which powers other portions of the bubble machine
which are described below. In the preferred embodiment, a hollow
cylinder is provided for rotation within the fluid tank. The hollow
cylinder rotates in response to torque from the hydraulic motor and
causes a constantly changing portion of ports to be alternately
open and closed. This, in turn, causes the water streams to be
intermittent. Throughout the rotation cycle of the hollow cylinder,
there are always one or more ports in the open position, so as to
allow the water to flow continuously. After flowing past the
impeller, the water flows into the hollow cylinder within the fluid
tank and is ported out via a plurality of channels that guide the
water into streams emanating radially outward and upward from the
fluid tank.
On a second side wall of the impeller housing is a sealed, second
opening for a geared axle. The axle is attached to the impeller at
one end thereof, and is rotatably connected to a second impeller or
fan. While the second impeller is not hydraulically ported to the
hydraulic motor, torque from the hydraulic motor rotates the geared
axle causing the second impeller to turn. Rotation of the second
impeller generates an air stream. A bubble solution container is
attached to the upper end of the bubble machine. The bubble
solution container has an opening in the top surface and a funnel
depending from the top surface into the inner cavity of the
container. A bubble wheel, having bubble openings at the periphery
of the bubble wheel, is positioned within the funnel and is
rotatably connected to an extension of the geared axle. Rotation of
the geared axle thus synchronously rotates both the second impeller
and the bubble wheel. The diameter of the bubble wheel is
sufficiently large such that an upper portion of the bubble wheel
is continuously outside of the bubble container and is thereby
exposed to the continuous air stream generated by the rotation of
the second impeller. When a thin film of bubble solution adheres to
the bubble openings at the periphery of the bubble wheel, the
continuous air stream generated by the second impeller creates a
continuous stream of bubbles.
Accordingly, in the preferred embodiment of the present invention
wherein both the bubble machine and the sprinkler portion are in
operation, it is an object of the present invention to provide a
fluid powered bubble machine with spill-proof capability by
connecting the lower impeller housing spout to a pressurized fluid
or water source. The water will turn the impeller, exit the
impeller housing through the upper impeller housing spout, enter
the fluid tank through the fluid tank attach spout, fill and
pressurize the fluid tank, exit through one or more aligned fluid
passage holes and fluid passage slots, and create amusing streams
of water. In response to the rotation of the impeller, the impeller
forward gear will turn the fluid drum gear. Turning of the fluid
drum gear will cause various fluid passage holes and fluid passage
slots to constantly align and misalign in a predetermined or random
pattern. The rotating rearward impeller gear will cause the coupled
female fan gear and fan to rotate. Rotation of the fan creates an
air stream directed at the bubble wheel. Rotation of the fan, fan
axle, and male fan gear also causes rotation of the bubble wheel
through the bubble trough. A plurality of bubble orifices placed on
the outer periphery of the bubble wheel thus rotates into the
bubble trough, picks up a thin film of bubble solution, continues
its rotation within the rectangular funnel until the bubble
orifices are protruding outside of the container. The air stream
"blows" bubbles with the bubble film thereby vacating the bubble
orifices. Continued rotation of the bubble wheel results in a
continued exposure of bubble film to the air stream.

the center, at least one bubble retaining flange 96 on the end of
the bubble wheel axle 94, and a bubble wheel gear 98. The male fan
axle 86 is adapted to mesh with and provide torque to bubble wheel
gear 98.
FIG. 2G shows a bubble solution container having a lower solution
container shell 100 and an upper solution container shell 110. The
lower solution container shell 100 is further defined as a shell
having a bubble solution trough 102, a connecting flange 104, an
attach receptacle 106, and a fill line 108. The attach receptacle
106 is adapted to snappingly attach to and supported by base attach
pin 26.
As is also shown in FIG. 2G, the upper solution container shell 110
is further defined as a shell having a funnel 112, a upper funnel
opening 114, a lower funnel opening 116, bubble wheel axle
retaining slots 118, a connecting flange 120, a fan axle trough
122, fan axle retaining flanges 124 and 125, and a filling spout
126. The lower solution container shell 100 and upper solution
container shell 110 are adapted snappingly attach together by
connecting flanges 104 and 120. The fill spout 126 is adapted to
threadingly attach to a cap 130. The bubble wheel axle retaining
flange 118 is adapted to snappingly attach to and support rotation
of the bubble wheel axle 94. The fan axle retaining slots 124 and
125 are adapted to snappingly attach to and support rotation of fan
axle 82.
The operation of the present invention can be seen by reference to
FIG. 1. When a pressurized fluid source is connected to the lower
impeller housing spout 54, the fluid will cause the impeller 70 to
rotate by creating a pressure differential on the impeller blades.
As impeller 70 rotates, male impeller gear 72 that is coupled to
female fan gear 87 causes the fan 80 to rotate. The rotation of
impeller 70 also causes impeller forward gear 71 which is meshed
with fluid drum gear 42 to rotate the fluid drum. The rotation of
fan 80 causes fan blades 88 to generate an air flow in the
direction of bubble wheel 90. As fan 80 rotates, male fan gear 86
that is meshed with bubble wheel gear 98 causes bubble wheel 90 to
rotate. The rotation of bubble wheel 90 causes bubble orifice 92 to
continuously travel through and be immersed in bubble solution in
bubble solution trough 102, to travel above funnel upper opening
114, and to expose refreshed bubble orifice 92 to the air stream,
thus creating bubbles. After entering through lower impeller
housing spout 54 and rotating impeller 70, the pressurized fluid
exits upper impeller housing 60 through upper impeller housing
spout 61 and simultaneously enters fluid drum 30 through fluid drum
attach spout 35.
After entering and pressurizing fluid tank 30, the fluid exits the
fluid tank through one or more fluid passage holes 32 and through
one or more fluid passage slots 46 and sprays outward. Fluid tank
30 and fluid drum 40 are adapted such that at any given point in
the bubble creation cycle and the fluid flow and spray cycle, at
least one fluid passage hole 32 and at least one fluid passage slot
46, will always be lined up with one another so to create a
constant fluid flow path.
As can be seen by reference to FIG. 2, bubble wheel gear 98 has a
diameter less than the diameter of the bubble wheel 90. The bubble
wheel 90 is prevented from inadvertently becoming detached from
bubble wheel axle retaining slots 118 by bubble wheel axle
retaining flanges 96. Retaining flanges 96 also act to keep bubble
wheel 90 from rubbing against the sides of funnel 112. Bubble
solution is poured into the interior of upper container shell 110
through fill spout 126 to a predetermined level as indicated by
fill line 108. The maximum fill line 108 is placed no higher on
lower shell 100 than to equal the volume defined by the maximum
liquid that can be held in the machine without running out of
funnel 112 when oriented in any position.
FIGS. 3-5 illustrate the additional unique advantages of spill
resistance when fluid is filled at or below the fill line 108 in
the subject invention regardless of the various possible
orientations. As is apparent from FIG. 3, when the invention is in
the upright position liquid will always be below the lower edge 116
of funnel 112. When machine 10 is in the upside down position as in
FIG. 4, the liquid will occupy the space immediately around funnel
112 but not be able to enter funnel 112 for discharge through
opening 114. When machine 10 is in a sideways position as in FIG.
5, the liquid level will always be between the side of the funnel
112 and the lower side of the two container shells 100 and 110.
Furthermore, when the machine 10 is oriented in any of an infinite
variations of the above described positions, it will behave in a
like manner and prevent the spillage of the solution.
As is seen by reference to FIGS. 1 and 2, in the preferred
embodiment, the fluid powered bubble machine of the subject
invention is mounted on a base with bubbles being blown from one
end and fluid emanating from the other. However, other embodiments
of the subject invention could readily be adapted to have the fluid
emanate from a vertical fluid tank and the bubble blowing portion
of the machine could be mounted above the fluid tank so as to
increase the elevation of the bubbles being blow. The entire
machine could also be readily adapted to take the from of a fire
hydrant, a cartoon character, or other aesthetically pleasing
shape.
Lastly, the preferred method of fabrication would be injection
molding for high volume low cost production. The material used
could be any of a variety of materials such as polyethylene,
polypropylene, polyester, nylon, etc. that are compatible with the
injection molding process.
While there is shown and described herein certain specific
structure embodying the invention, it will be manifest to those
skilled in the art that various modifications and rearrangements of
the parts may be made without departing from the spirit and scope
of the underlying inventive concept. The subject invention is not
limited to the particular forms herein shown and described except
insofar as indicated by the scope of the appended claims.
