Description
BACKGROUND OF THE INVENTION
One of the most disagreeable household tasks yet unaided by the
advance of science, is the shining of shoes, a fact believed to
result from the lack of creativity and invention contributed to
data in the field.
The present inventions relate generally to the use and refinement
of manually operated shoe polishing devices employing an aerosol
can containing shoe polish. Though obvious in concept, utilization
of the aerosol can as such in this context does not, to applicants'
knowledge, reflect in any prior invention, although Petion, U.S.
Pat. No. 2,972,768, issued on Feb. 28, 1961, does refer to a
"pressurized container" which in the drawings resembles a small
cylinder tank with a novel escape valve. However, in Petion the
need to use both hands to (a) depress a knob (No. 54 on Sheet 1) on
the cover and (b) to simultaneously turn the elongate base plate
from one position to another, made it impossible for a person to
perform all of the traditional operations in the polishing of a
shoe without causing the hand holding the shoe to repeatedly divert
its grasp to engage in extrinsic tool manipulations. The inventions
claimed in our copending application, as further improved by novel
and useful additions and changes now to be described, permit the
hand holding the shoe at all times to retain its grip firmly on the
shoe while the hand holding the device never loses contact with it
during the entire sequence of traditional cleaning and polishing
operations.
In a context in which millions of persons can be immediately
assisted at low cost to conserve time and strength, any useful
improvement admittedly novel should warrant serious patentable
consideration. Each of the novel features now to be discussed
contributes to make more accessible (because of their economical
cost), more convenient and more useful, shoe shining devices
containing an aerosol with polish. It is believed that taken as a
class these devices stand as the first significant technological
advance in the art for centuries.
SUMMARY OF THE INVENTION
It is a general object of this invention to provide novel
integrated shoe cleaning-polishing devices which may be held in one
hand through the traditional sequence of cleaning and polishing
procedures while the other hand at all times retains its original
fast grip on the shoe, completing all of said tasks in a simplified
and economical manner, and some embodiments of which devices
accomplish all of the foregoing steps without allowing the motor
hand to be dirtied by direct contact with the dauber, brush or
buffer.
A purpose of the inventions claimed is the disclosure of new means
of securing a fabric (lambswool, cloth, etc.) shoe polishing buffer
onto a housing contoured to the circumference of an aerosol can
containing shoe polish, contributing to create thereby an
integrated device for the polishing of shoes.
It is a further specific object of this invention to suggest means
of attaching a shoe polishing brush to said device, by which the
device may be more expeditiously constructed and an improved
aesthetic appearance achieved.
Yet another object teaches means of receiving and retaining aerosol
cans in durable housings formed and contoured to the approximate
circumference of said cans, allowing their insertion and removal
without undue pressure or other strain on said housings.
Yet another object of the inventions here described is the use of
identification windows within a sleeve-housing utilized as a shoe
cleaning-polishing device, providing a means of
contents-identification as well as economy in manufacture.

DETAILED DESCRIPTION
Referring now to the drawings more in detail wherein like numerals
designate like elements throughout the various figures, FIGS. 1
through 6 show a preferred embodiment of the present invention
reflecting improvements contained in this continuing application.
It will be noted that this device is in effect a sleeve housing 11
in which a replaceable aerosol can 15 is lodged. The lower end of
the sleeve-housing is closed, and protruding from said end a dauber
17 is positioned under a removeable protective cap 19 to be
conveniently used also as a base. As FIGS. 1 through 6 incorporate
most of the novel features claimed herein as invention, they will
now, following this initial general disclosure, be examined in
greater detail as the subsequent drawings and explanation make this
preferred embodiment the more easily understood.
In FIG. 1 we look down at the same device pictured frontally in
FIG. 3 as it stands in an upright position on its lower
dauber-protective cap 19. In FIGS. 1 through 4, an aerosol can 15,
containing an expressible shoe polish, is shown in planned
conjunction with the housing: The broken-away portion of FIG. 2
illustrates the manner of firmly lodging the can within the
housing, namely by employing bosses 20 in wedging relationship with
its lower chime 38.
One notes in FIG. 3 the cut away portion of the compensator ring
(coordinate plastic ring-collar) 14. Once this compensator ring 14
is placed upon the aerosol can's upper chime 38, the can is in
condition to be inserted into the sleeve housing 11. It is in this
closed position that the can, the ring and the housing appear in
assembled relationship in FIGS. 1, 2 and 4.
Affixed to this sleeve housing 11 are a buffer 12 and a
longitudinal brush 13 as well as dauber brush 17. In some
embodiments it will not be necessary to utilize the dauber brush
17, which would in turn obviate the necessity for dauber protective
cap 19: Under such circumstances, the added diameter footings 18
permit the unit to stand upright freely without additional support.
The inventions contained in FIG. 5 are explained in greater detail
in the multiple blown-up Figures appearing hereinafter.
BUFFER ATTACHMENT MEANS
The attachment of a buffing surface to a buffer handle has been
traditionally achieved thusly: A lambs-wool or other fleecy
material is positioned over a cushioned under-bed, then fixedly
attached at both ends of a rectangular, flat backing. In the case
of a plastic sleeve-housing into which neither nails, staples nor
screws can be reliably fastened, different means must be supplied
by which to fasten the buffing material to the housing, it being
operatively insufficient that said ends be simply glued or sewn
onto the top and ends of the under-bed. Several such novel means
are now described, without attempting thereby to limit the scope of
the invention as hereinafter claimed.
FIG. 7 shows the buffer 12 on its traditional under-bed 21: FIG. 8
shows a cushioning material split equally into two parts 21
longitudinally, placed over a plastic under-bed in the nature of a
platform which is similarly split longitudinally and raised above
the level of the upper wall of housing 11. This leaves a passageway
or channel 25 between the raised plastic underbed and the housing
shell, as well as a slight separation between the divided underbed
halves. This divided resilient support remains capable of
cushioning the buffing fabric 12 despite the presence of the center
air strip running its entire length.
A strip of buffing material 12 (FIG. 9), somewhat longer than the
whole length of the buffer bed, is made into an endless belt (FIG.
10) by sewing to each of its two ends, one end of a piece of
elasticized material 12A. Taking the buffer shown in FIG. 10 in two
hands, with the thumb and forefinger of each over the sewn joint,
it can be seen that the elastic 12A may be pulled apart a
sufficient distance to allow it to pass between the divided plastic
under-bed platform of the sleeve-housing, over each side of which
the sponge rubber strips 21 have been placed. As thus extended the
elastic is moved longitudinally in a sliding motion through the
free air space between the sides of resilient supporting material
21, twisting down into passageway 25 where it is allowed to
contract thereby pulling closer together the ends of buffer 12 and
creating a snug total relationship with the sponge rubber 21 and
plastic under-beds.
This solution provides a convenient and aesthetically refined
buffer-attachment by a means requiring a smaller amount of
resilient supporting material 21 (due to the dividing air space),
and whereby the buffer ends finally are securely affixed in the
interior of the housing at a spot not otherwise accessible. The
buffer 12 may be removed by again stretching the elastic 12A,
allowing it to be easily slid out between the supporting sponge
rubber 21 and plastic under-bed sides. This solution would as a
practical matter not be possible if only the lambs wool or other
fabric were utilized in an endless belt, due to the difficulty to
be encountered in gluing the supporting resilient material onto the
plastic bed and at the same time achieving a snug fit of the buffer
fabric over the resilient supporting material 21: The passageway 25
dimensions would not only have to be measurably increased to
accommodate lambs wool which varies between five-sixteenths to
three-fourths inch in thickness, but a long aperture of a depth
suitable for such heavy material would be aesthetically
unattractive, yet necessary to prevent the crowding of the
material.
It will be also noted that upon use many buffing fabrics elongate:
Where the ends are fixedly attached at the ends of the buffer bed,
the growing slack in the material becomes offensive, yet there is
no provision for its disposition. The use of elastic 12A in the
buffer 12 under-structure (see FIG. 10) automatically contracts the
exposed buffer surface to obviate this "surplus goods" problem
produced by elongation through use.
Other means of attaching buffing material 12 to a plastic base of
housing 11, where a supporting resilient material 21 must cushion
the buffer, is shown in FIGS. 12 through 16a. Here resort is taken
to a plastic wedge 26 having teeth 27 which engage with similar
teeth 27A on the interior sides of the passageway 25A. By first
placing the ends of the buffer in passageway 25A, then compressing
wedge 26 and causing it to pass into the passageway 25A, the wedge
26, having increasing width and increasing thickness (see FIG. 15),
securely fastens the fabric at the end of the channel. Once the
teeth 27 of the wedge engage with the teeth 27A of the interior of
the passageway, the buffer is held securely by pressure of the
wedge. Note that this solution does not contemplate a divided bed
of resilient material 21, but rather a solid bed 21A over a
passageway 25A which no longer needs to be split to allow
longitudinal sliding entry of the elastic.
Another species of wedge 26A is shown in FIG. 16 and 16a, in which
the teeth 27 of the wedge engage against similar teeth 27A in the
lower bed of channel 25A (in FIG. 16), compressing hard sponge-like
material 28 between the jaws of the wedge, with the reversed upper
teeth 27B of the wedge preventing the withdrawal or slippage of the
buffer fabric once the wedge 26A is properly positioned. In both
this and the preceding embodiments the wedge may be withdrawn and
repositioned at any time to take up slack in the buffer 12 created
through use. on
A further means of attaching buffing material to a plastic housing
for use as a shoe polishing device is shown in FIGS. 19 and 20.
Lambs-wool 30 or similar fleecy fabric is cut to a width slightly
greater than that of the under-bed 21A, and a length greater than
that of its bed 11A, with the excess goods at both ends being
turned under and sewn transversely at 32A into an open loop 32
(FIG. 19). Such a loop, when slid over the end pins 31 shown in
FIG. 20, provides a solid means of affixing the buffer to the
device, and permits easy replacement of the buffer when it has
become worn.
Each of the aforesaid means of attaching the buffer to the device
performs useful purposes not otherwise nor previously achieved by
any buffer or similar device known to applicants.
BRUSH ATTACHMENT MEANS
The attachment of a polishing brush to a sleeve-housing of this
character, purposing to achieve thereby a shoe polishing device at
least partially integrated, presents a fastening or adherence
problem aggravated by the active use to which the brush will be
put.
Reference is made to a commercial product sold under the trademark
BRUSHLON (FIG. 17), consisting of an underlayment of urethane 29
into which are adhered thousands of bristles 13 in intensive
placement thereon. The BRUSHLON underlayment 29 is of uneven
height; viewed from the side (FIG. 17) its base presents an
undesirably irregular appearance when used as a basic part of a
consumer product such as a shoe shining device for personal use.
However, the use of BRUSHLON in the present integration is
otherwise advantageous because it may be easily cut to any size,
and may be readily glued.
FIG. 18 shows a cut-away upper portion of a sleeve-housing 11
running the approximate length of a coordinate aerosol can. The
gallery 11B surrounding its upper perimeter is believed to be both
novel and useful in the following respects: First, it places a wall
in front of and slightly above the brush's underlayment 29 around
its entire edge, thereby concealing its irregularity as well as the
rough jointure of the otherwise flat backing of the device 11 with
the flat base 29 of the brush. Second, in the production process
where manual or even machine placement of a brush element on an
otherwise flat surface is necessary, misplacement may easily occur:
Where there is a known recess of fixed dimension and shape into
which an object of similar size and contour can be quickly placed,
the problem of misplacement is avoided inasmuch as the brush can
only be lodged accurately within the recess if it is to be placed
there at all. Third, the capability of the brush, when used, to
withstand lateral and longitudinal pressures and movements is
greatly increased where its sides are encased within and lodged
against firm walls: The gallery 11B provides a solidity without
which the effectiveness of the BRUSHLON material for such purposes
is significantly diminished. Fourth, a device of this character
receives hard handling; while in use it is in almost constant
contact with shoes. Were the gallery not utilized, the corners
especially of the brush material would receive incessant bumping
and knocking; by utilizing the gallery or "shield" around its
corners the brush will not be repeatedly thus pried loose from
adherence to the base.
AEROSOL CAN INSERTION AND RETENTION MEANS
It has been found that the sleeve-housing device pictured in FIGS.
21 and 23 may be most economically cast first in two lateral halves
as the cost of an injection mold (for quantity production of
plastic pieces) is greatly increased by its depth; the halves are
then joined by gluing. When a can is inserted into the housing, the
upper end of this device (it being there just large enough to admit
the can) is subjected to a strong horizontal outward pressure at
the moment of the passage of the chimes 38 (the enlarged diameters
of metal at top and bottom of can). Unless precautions are taken
such lateral force being often reapplied must in time separate the
upper portion of the longitudinal halves of the housing at their
common joint.
Applicants have devised a novel means of harmlessly diverting this
separating force caused by the can's insertion and removal, without
impeding the convenience of its use. Reference is made to the six
(which number may be greater or less than six) flexible extensions
33 appearing in FIGS. 21 and 23, which extensions are integrally a
part of housing 11. A circle may be drawn touching the innermost
tips of the aforesaid extensions 33: This circle, being of lesser
diameter than the circle formed by the chime 38 of the inserted can
15, must be increased in size in order to permit the can's
insertion. At the moment of insertion the angle of force upon the
extensions 33 lies in a horizontal plane: However, this force does
not act directly on the joint which adheres both halves of the
whole housing, but rather simply pushes back the six raised,
flexible extensions 33, resulting in a fulchrum or hinge effect at
their bases. After the chime passes, the extensions return to their
original positions and serve to hold the can firmly within the
housing.
The profile construction of the extensions 33, as shown in FIGS.
24, 25 and 26, discloses that their thickness increases generally
as they ascend, then attenuates at their tip. Upon upward removal
of the can the lateral pressures commence just above the level of
the housing top; these grow more severe as the can rises, reaching
their most destructive force at the upper level of the extensions
33 where the sideward force is imparted least of all to the main
device's common longitudinal joint, being spent instead in the
flexing of the extensions.
FIG. 27 discloses a type of protrusion or extension different from
the others pictured in that the "nib" or plastic extension points
downward rather than up. This configuration operates especially
well if the sleeve housing has an open lower end on which similar
protrusions have likewise been placed so that the can is retained
by such protrusions at both ends serving to retain it snugly from
within.
As an alternate construction, the extensions 33 may be affixed to
an annular upstanding neck such as neck 24 pictured in FIG. 34 (but
without machicolations), or as integral parts of a separate ring
affixed to the said neck.
COMPENSATOR RING (COORDINATE RING-COLLAR)
TO ACCOMMODATE VARYING CAN DIAMETERS
The importance of the aforesaid destructive force is greatly
aggravated by one condition which prevails generally in the United
States today within the can industry. For reasons peculiar to their
own steel procurement and manufacturing processes, the large "tin"
can companies such as American Can Company and Continental Can
Company refuse to warrant the outer dimensions of the chimes of
cans of the general sizes here under discussion. Not only will
these can companies not assure purchasers of a responsible
tolerance in said diameters, as, for example, plus or minus one
thirty-second inch; but the can companies will in fact not warrant
or even express these outside dimensions within any tolerance
whatever.
It is obviously difficult to design plastic sleeve-housings to
snugly accommodate cans of great potentially varying diameter; if
such housings are merely designed for cans of the "usual" external
dimensions, a minority of cans might be of a width, say, one-eighth
inch greater than the average and these few could critically damage
the sleeve-housings upon their forced insertion and removal. One
novel and useful method of achieving secure retention of the can
yet with a flexibility sufficient to allow cans of varying external
chime dimension to be reliably inserted into a sleeve-housing
having a neck of constant circumference, involves the utilization
of a compensator ring as now described. See FIGS. 28-34.
A ring 14 made of a flexible plastic-like material is affixed to
the top chime 38 of the can of polish by means of multiple hooks 35
which descend at planned intervals from the ring's inner
circumference. These hooks are of a length and shape such as to
flexibly accommodate the forced insertion of cans of varying
diameters, said hooks 35 gripping the can 15 from underneath the
upper chime 38 when the ring is forced solidly down over the top of
the can. See FIG. 32. The can is prevented from moving upward
relative to the ring 14 by arcuate lips integrally a part of said
ring.
Whereas the housing neck 24 is greater in diameter than the inner
circumference of the compensator ring 14 and than the circle (of
flexible diameter) of hooks descending therefrom, it is less than
the diameter of the ring's outer circumference from which a side
wall descends. (FIG. 32) When assembled, an annular protrusion 36
on the inside of the outer wall of the ring forms an interference
fit with a similar raised circumference 37 on the outside of the
neck of the housing; both pieces preserve a constant diameter and
their respective raised circumferences 36 and 37 coact compatibly
to insure the can 15 being held securely within the device.
As alternatively shown in FIGS. 33 and 34, the neck 24 of the
housing 11 may be of a slightly lesser diameter, but slotted with
machicolations 39 of a size, shape, placement and number determined
by the size and positions of the hooks 35 descending from the
inside circumference of the snap ring compensator. When the ring is
positioned on the can and the can inserted into the housing (FIG.
33), the backs of the hooks protrude laterally from the can's upper
circumference into their respective slots cut out of the neck
specifically to accommodate such protrusions. Where an unusually
large chime diameter 38 forces the hooks far backward, the
machicolations in the neck easily accommodate the excess by
permitting the backs of the hooks to further enter the cut-out
voids 39.
Under both alternatives described above, whereas the tips of the
hooks 35 (normally but not necessarily spaced equidistant about the
inner circumference of the ring) can create circles of different
diameters depending upon the diameter of the inserted can, by means
of the novel compensator ring described the can is lodged solidly
within the ring (by its circle of hooks) and the ring itself is
thereafter lodged firmly over and on the housing by means of its
outer rim of constant diameter interacting with the constant
diameter neck 24 of housing 11 being both unaffected by variances
in chime 38 diameter.
IDENTIFICATION WINDOW FOR AEROSOL HOUSING
Reference is made to FIG. 35 in which an aerosol can (15, in dotted
line) has been placed within a sleeve-housing 11 which provides
circumferential backings upon which the polishing tools (brush 13
and buffer 11) are conveniently placed. The use of such a housing
normally creates a problem of contents-identification in that, if
made solidly, the walls of the housing preclude the user or viewer
from reading or otherwise learning the contents of the enclosed can
as described on the can's label. This defect is better understood
in the knowledge that the sleeve-housing is designed to accommodate
easiest insertion and withdrawal of random aerosols, thereby
encouraging it to serve as a vehicle to dispense and to apply
polishes of different colors, e.g., black, brown. Thus one
utilizing the device occasionally with different aerosol inserts
would not be able to know from looking at the outside of the
device, what the color then contained in it might be. To alleviate
this problem and achieve other useful purposes now described, an
identification window is disclosed in FIG. 35 by which the viewer
or user may at once determine the nature of the contents simply by
looking "through" the window of the device at the contained can's
trade dress.
The cost of devices of this character, manufactured for consumption
on a mass basis, is in large measure determined by the weight of
plastic used therein. By creating a window in one (or more) side of
the device, a significant amount of plastic is saved without
sacrificing strength or function. A further economy is achieved in
that by utilizing the trade dress already on the can anyway, it is
unnecessary to place lettering or an identifying label on that side
of the shoe device. Labels of a type appropriate for this usage
cost in quantity from 1 to 3 cents each, possibly more depending
upon the material used: But even the most durable commercial
labels, e.g., printed foil, do not withstand the expected heavy
manual use of this type of device, as after even mild use these
become tattered. Cost-savings directly flowing from the omission of
such a label on the device and from the reduction in weight of the
plastic material required, are such as justify the use of such an
identification window on an economic basis alone, quite apart from
the functional contribution of the window.
The window pictured in FIG. 35 does not exhaust the scope or nature
of the invention described. The window may thus be long and narrow,
or there may be two or more windows critically placed on the
housing device to disclose information or serve other express
purpose. See FIGS. 36 and 37. The identification window concept can
be also embodied on a second or even three or four sides of any
housing in which an aerosol can is contained for storage or
utilitarian purposes. It is clear that the scope of the invention
in relation to housings for aerosol cans goes farther than
reference solely to shoe cleaning and polishing devices.
A full explanation of the identification window must include
reference to the trade dress used upon the can placed within the
device. It will be noticed that the dimensions of the window in
FIG. 35 are of a specific, known size: In the unrolled, flat
representation (FIG. 38) of the trade dress (which in production
would be either printed directly on or in the form of a label
wrapped around the aerosol can as in FIG. 39), these same
dimensions are directly adopted for correlation with the window
aperture. The trade dress pictured in FIG. 38 is divided laterally
into segments of equal size; the size of the segments is determined
by the size and text requirements of the label interacting with the
window shape and configuration of the housing. It is stressed that
the correlated trade dress or label and identification window are
co-equal features of the invention and coordinate parts
thereof.
AEROSOL SHOE SHINE DEVICE WITH DIRT-FREE HANDLE
It will be noticed in FIGS. 2, 3 and 4 of this continuing
application, for one to clean and polish shoes utilizing the
devices there pictured presents the possibility of dirtying the
motor hand (i.e., the hand holding the device) by its contact with
longitudinal brush or buffer. It has been found through extensive
experiment that with aerosol devices employing buffer, brush and
dauber virtually no dirt does in fact reach the hand when holding
the device from either the brush side or the buffer side. However,
some persons will no doubt dispute this, and large numbers of
persons will conclude, however erroneously, in considering the use
of these devices, that their hand would become dirty by touching
the brush or the buffer.
A perhaps unreal, but nevertheless practical problem therefore
tends to thwart public acceptance of this device, in that there is
a natural disinclination on the part of many persons to permit
their hands to fall in contact with a surface which, rightly or
wrongly, they consider to be dirty. The inventions pictured in
FIGS. 40 and 42 solve this problem. A person grasping handle 43 has
at his immediate control without changing the hand's position on
the device, both brush and buffer: In neither case does the hand
come in contact with an offensive surface.
A further embodiment of the "aerosol side handle" concept is
pictured in FIG. 41, in which to obtain a slightly more comfortable
working position than is available in the configuration shown in
FIG. 40, two handles have been constructed, each directly opposite
a working surface. Hand contact with any working surface is again
totally avoided. Although this device becomes somewhat more
cumbersome in its employment, it nonetheless presents the same
dramatic capability of the other devices pictured in this entire
application, in which it is possible for one hand alone, without
for an instant losing physical contact with the device, to perform
all of the multiple steps in the polishing of a shoe while the
other hand at no time relinquishes its grip upon the object
shoe.
FIGS. 44, 45 and 46 show alternative handle designs that may be
employed with the embodiments of FIGS. 40 and 41.
The scope of the inventions described is set forth in the claims
hereinafter following, and is not confined merely to the precise
alternatives described above.
