United States Patent 3,048,867 SHOE CLEANER Paul Counts, RFD. 4, Box 62, Jonesboro, Ark. Filed Oct. 3, 1966, Ser. No. 60,164 8 Claims. (Cl. 15-36) This invention relates to a novel and useful shoe cleaner and more specifically to a shoe cleaner assembly which is adapted to be recessed within a section of flooring with the upper surfaces thereof substantially planar with the upper surfaces of the flooring.

The shoe cleaner is designed to take its place in the modern type of living of today and the future and for use in both public and private life. It is constructed in a manner whereby its initial cost of manufacture and maintenance cost will be maintained at a minimum and its installation in at least public places will result in savings in cleaning maintenance that will more than offset the cost of the shoe cleaner. It will hereinafter be readily apparent that the shoe cleaner can be made in any size to suit the present demand and that the portions of the shoe cleaner which are visible may readily be designed to pro vide a pleasing appearance.

The main object of this invention is to provide a shoe cleaner which will be completely automatic in operation and be highly effective in removing dirt and other foreign material from the soles of shoes worn by persons walking over the shoe cleaner.

A further object of this invention, in accordance with the immediately preceding object, is to provide a plurality of brush rollers each equipped with brush bristles which when disposed immediately beneath a grillwork with the upper end of the bristles carried by the upper portions of the rollers projecting through the grillwork and rotated will be highly efiicient in removing foreign material from the undersurfaces of shoe soles positioned on the grillwork.

A further object of this invention is to provide a means for resiliently mounting the grillwork of the shoe cleaner for limited vertical movement whereby a motor means for the brush rollers may be actuated by a switch engageable by the grill work as it is depressed when a predetermined amount of weight is placed thereon.

Still another object of this invention is to provide the shoe cleaner with receptacle means for collecting foreign material removed from shoes and means for mounting the receptacle means immediately beneath the brush rollers whereby the receptacle will collect substantially all of the foreign material removed by the shoe cleaner.

A still further object of this invention, in accordance with the immediately preceding object, is to provide the receptacle means disposed beneath the brush rollers with suitable heating elements in good heat exchange relation with the interior of the receptacle means and the undersurface of the frill whereby snow and ice clinging to the soles of shoes positioned on the grill may be melted.

A final object to be specifically enumerated herein is to provide a shoe cleaner which will conform to conventional forms of manufacture, be of simple construction and automatic in operation so as to provide a device that would be economically feasible, long-lasting and capable of operating only when necessary.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which: FIGURE 1 is a perspective view of the shoe cleaner;

FIGURE 2 is a longitudinal vertical sectional view of the shoe cleaner on somewhat of an enlarged scale taken substantially upon a plane passing through the longitudinal center line of the shoe cleaner;

FIGURE 4 is a side elevational view of the shoe cleaner with parts thereof being broken away and shown in section showing a modified form of shoe cleaner construction utilizing a vacuum for discharging the foreign material removed by the brush assembly of the shoe cleaner and heating elements for melting snow and ice from the shoes positioned on the grillwork of the shoe cleaner;

FIGURE 5 is a side elevational view similar to that of FIGURE 4 but of a shoe cleaner not provided with the vacuum means;

FIGURE 6 is a fragmentary enlarged vertical sectional view showing the manner in which the grillwork of the shoe cleaner is resiliently mounted for limited vertical movement; and

FIGURE 7 is a perspective view of the removable portion of the receptacle used in connection with the forms of the invention illustrated through FIGURES 1 through 3 and FIGURE 5.

Referring now more specifically to the drawings the numeral 10 generally designates the shoe cleaner comprising the instant invention which includes a mounting plate 12 comprising a top wall for a housing generally referred to by the reference numeral 14 including

opposite end walls

16 and 18,

opposite side walls

20 and 22 and a bottom wall 24. An opening 26 is formed in the mounting plate and a grillwork generally referred to by the reference numeral 28 is disposed in the opening and includes a generally rectangular framework 30 including a plurality of parallel longitudinal grill elements 32 which are interconnected by means of a plurality of longitudinally spaced and transversely extending parallel grill elements 34.

With attention now directed more particularly to FIG- URE 6 of the drawings it will be noted that the frame work 30 includes a depending peripheral flange 36 which extends about the outer peripheral edges of the frame 30. The frame 30 includes a plurality of depending guide rods 38 which are secured at their upper ends to the frame 30 in any convenient manner such as by welding 40. The mounting plate 12 includes a plurality of opposite side and end L-shaped mounting flanges generally designated by the reference numeral 42 which each have the upper end of their vertical leg 44 secured to the undersurface of the mounting plate 12 adjacent the edge of the opening 26 formedtherein. The horizontal leg 46 of each bracket '42 is provided with at least one bore 48 through which the lower threaded end portion 50 of a guide rod 38 is slidably disposed. A stop member in the form of a nut 52 is threade'ly engaged with the portion of the guide rod 38 extending below the horizontal flange 46 and a compression spring 54 is disposed about the guide rod 38 and has its opposite end in frictional engagement with the undersurface of the frame 30 and the confronting surface of the apertured end wall 56 of the sleeve 58. The remote surface of the end wall 56 is in surface to surface contacting relation with the upper surface of the horizontal flange 46 and the upper end of the sleeve 58 comprises a stop for limiting downward vertical movemeut of the grillwork 28. The coil springs 54 normally resiliently urge the grillwork 28 toward its upper limit position defined by the nut 52 and thus it will be seen that the grillwork 28 may be urged downwardly against the coil springs 54 upon the placement of a given amount of weight on the grillwork 28.

The housing 14 includes a pair of longitudinally extending support angle brackets 60 which each has secured thereto a plurality of bearing journals 62. Each bearing journal 62 on one of the angle members 60 is aligned with a corresponding journal 62 on the other angle member 60. Aligned pairs of bearing journals 62 rotatably journal the opposite end portions of a plurality of roller shafts 64 which each have mounted thereon between their opposite ends a brush roller member generally referred to by the, reference numeral 66 including a plurality of radially extending brush bristles 68.

' The. brush rollers 66 are disposed between adjacent transverse grill elements 34 and the upper ends of the bristles 68 thereon project above the grillwork 28 between adjacent transverse grill elements 34 as can best be seen in FIGURES '1 and 2.

The end of each roller shaft 64 is provided with a pulley 70 in alignment with the drive pulley 72 carried by the output shaft 74 of a conventional form of electric motor 76. and an endless flexible belt 7 8 is utilized to drivingly connect the drive pulley 72 with the pulleys 70 on the roller shaft 64. Attention is directed to FIGURE 2 of the drawings wherein it will be noted that the endless flexiblemem'ber 78 is engaged with the pulleys 70 in a manner whereby adjacent brush rollers 66 are rotated in opposite directions.

With attention now directed to FIGURES l and 2 of the drawings it will be noted that the motor 76 includes a junction box '80 and that a pair of

conductors

82 and 84 extend from the junction box 80 to a pressure switch 86 mounted beneath and for engagement by the lower edge of a portion of one of the peripheral flanges 36 of the frame 30. The junction box is connected to a suitable source of electricity by means of suitable conductors (not shown) and the pressure sensitive switch 86' is disposed in the electrical circuit for the electric motor 76 and is normally open. The placement of a predetermined amount of weight on the grillwork 28 will urge the latter downwardly against the tension of the coil springs 54 and engage the pressure sensitive switch 86 to close the circuit to the electric motor 76. Also interposed in the electric circuit to the electric motor 76 by means of conductor 88 is a toggle switch 90 whereby the electrical circuit of the electric motor 76 may be opened upon actuation of the toggle switch 90.

Receptacle means in the form of a receptacle housing generally referred to by the reference numeral 92 and including a pair of downwardly

convergent side walls

94 and 96 and interconnected by means of a pair of downwardly convergent end Walls 98 and 100. The lower edges of each of the walls 94100 terminate in inwardly directed support flanges 102 by which a removable receptacle 104 is supported in the lower end of the housing 92. The wall 100 has a plurality of laterally struck

portions

106 and 108 defining an opening 1:10 through which the receptacle 104 may be removed by means of elongated handle 112 secured at its lower end to the outturned upper lift 114 of the receptacle 104. The mounting plate 12 is provided with an access opening 116 having a closure therefor hinged as at 120. The hinged closure 118 may be opened in order to remove the handle 112 and the receptacle 104 from the housing 114. In this manner, the foreign material removed from shoes by means of the roller brushes 66 may be periodically removed from within the housing 92.

With attention now directed more particularly to FIG- URES 4 and of the drawings there will be seen two modifications of the shoe cleaner which are identical in substantially all respects as the previously described shoe cleaner 10. The shoe cleaner illustrated in FIGURE 4 is generally referred to by the reference numeral 122 and instead, of being provided with the receptacle 104 at the lower end of the housing 92, the shoe cleaner 122 is provided with a vacuum assembly 124 having a blower member 126 disposed therein and driven by a suitable electric motor 128. The vacuum 124 is provided with an outlet conduit 130 extending through the end wall 132 of the shoe cleaner 122 and may be communicated with any 4 desirable container for receiving foreign material removed thereby. The electric motor .128 is provided with a suitable conductor 164 connected to the junction box whereby the motor 128 may also be actuated by a pressure sensitive switch (not shown) connected to the conductors 32 and 84.

The electric motor 128 is also provided with a junction box 136 from which a conductor 138 extends and is connected to a third junction box 148. A plurality of

electrical heating assemblies

142, 144 and 146 are provided with

conductors

148, 1150 and 152 respectively and are secured to selected walls of the housing 154. The

conductors

148, 150 and 152 are each connected to the conductor 138 within the junction box 140 and a suitable toggle switch 156, see FIGURE 1, is disposed in the electrical conduit 134 whereby the toggle switch 156 may be utilized to render the vacuum means 124 and the

electrical heating elements

142, 144 and 146 inoperative. It is of course to be understood that the

heating elements

142, 144 and 146 could alone be operatively connected to the toggle switch 156 whereby the toggle switch would then be operatively connected to the electric motor for driving the rollers brushes of the shoe cleaner 122 and the vacuum 124 of the shoe cleaner 122. In this manner, the electrical heating elements could be disconnected during the warmer months.

With attention now directed to FIGURE 5 of the drawings there will be seen a still further modificaction of the shoe cleaner generally referred to by the reference numeral 158 which combines the removable receptacle feature 104 of the shoe cleaner 10 with two of the

heating elements

142 and 144 of the shoe cleaner 122. The shoe cleaner 158 also includes the wall of the housing 92 which is provided with the laterally deflected

portions

106 and 108 whereby the receptacle 104 may be removed by means of the handle 112 through the hinged closure 118 which is also provided in the shoe cleaner 158.

Thus, it may be seen that the

shoe cleaners

10, 122 and 158 are similar in many respects with the shoe cleaner 158 differing from the shoe cleaner 10 only in the addition of the

heater elements

142 and 144 together with the suitable controls therefor. The shoe cleaner 122 differs from the shoe cleaner 158 by the provision of an additional heater element and the vacuum 124 and the control therefor.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
