Walls 14; secured to a frame structure I12, and a bottom wall 28 having casters I6 ailixed thereto for the rolling support" of the cabinet from one place. of use to another. A compartment or chamber 18 is provided in the uppermost part of the cabinet [0 for housing, shoe. cleaning and polishing accessories within the same, access being had to its interior through front openings normally closed by doors 20. The'. front side of the cabinet H)- includesan inclined" central wall 24 connecting the upper portion below the doors with a. lower vertical wall pore tion 26.
vided with an open'ing 92 through which.v the} Interiorly of the cabinet l0, upon its bottom wall or floor 28, is mounted an electric motor 30] having itsv rotor shait 32 provided with a grooved, pulley. 34 to drive a 'V'-belt 36. The belt 36 6.0. meets the pulley 34 with a smaller grooved. pulley 3 8 keyed. ona line shaft 40 which is supported in bearings 42 secured; on the floor 28. A second grooved pulley M approXimating the pulley 3.8' on the line shaft 43 insize, is also keyed. oa hs. line shaft 40; and isf connected by a, V-beltlJG. to. a large sized grooved-pulley 4 8, which is keyed to asha'it 5B having a crank 52. This s arpen. is journaled in bearings carried by. standards .orposts 54 arising from the 11001728.
Thecrank 52 is proyidedwith a'bearing 58 for one end, of a pitman' or arm 56 which has.. its other end providedwith a channeled cross-arm 6G for the securement oi one end of a shoe shining cloth or web 62 in its channel. The web 62 extends. upwardly from the cross-arm. and has a central portion fhorizontally disposed and. supported, by elastic straps 64. engaged on studsor pins 66 projecting". from a. horizontal frame member 68. The opposite end portion ofi the web fit depends fromthe supporting straps G4 andis secured by a. plurality of elastic straps 72 which have their ends clamped between aplate l4 and the floor 28 by fmeans of. bolts 16. Thus, the. web t2v is of inverted. U' configuration as. shown in Figure 1, withits bight 18 of suflici'ent length to providespaee between its pendent por tions' for the positioning. of the foreshoe therein for polish; g. I
A foot support i cured to the lower front wall 26' andon'e of th posts. 54 and extends horizontally beneath the bight 1B of the polishing. web 62. A substantially U-shaped spring 84 is mounted onthe margin- 82 of the heelportion oi'I the foot support 80 and has its uppermost-[leg- BB en'gaged by a rod aafa d its other iegjsc prorod loosely depends. I 'herbd 86 also loose depends through an. openingfld formed in thei heel margin 82'ofthefoot support 80 and extends downwardly for connection with the blade 98 of a knife switch 98 that is mounted on theiiocr 28.
A tension spring; lllfl lilias' one end c'onne'cted by a pin I02 to the rod 86 and itsother end. by a pin I04 to the lower front wall 26. Pressure of the heel of the foot resting on" the suppflrt 80' on the uppermost leg 88 of the spring 84 depresses the rod 86 to close the switch blade 96 on the contacts of the switch 98. and places the spring (0!) un'dert'en'si'on and this, uponflthe removal orheelpressure from the leg 88';j of. the spring 84; returns the rod 86 to" its" norniali'y part of -aj 3 elevated position, the upward motion of the rod 86 withdrawing the switch blade 96 from the switch contacts to open the circuit on the motor 30.
A coin receptacle or box I06 is mounted within the cabinet I and has a hinged. bottom I08, which isto be locked in closed position by means of a padlock (not shown) engaged with a hash I I0. A coin chute I I2 leads from the receptacle and connects with a receiving slot II4 opening through the inclined wall 24 of the cabinet The coin chute I I2 includes front and rear walls I I6 and I I8, respectively, connected by side walls I20. These walls are made from an insulating material, and the rear wall H8 is hingedly connected. as at 8', with the inclinedwall 24, and it, together with the front wall II6, carry electrical conductors I22, substantially asisbest shown in Figure 2. These conductors I22 coriverge in a downward direction, so as to hate their lower ends spaced apart sufficiently only to be bridged by a coin passing downwardly "of the chute II2 from the receiving slot II4."
jFixedly secured to the rear wall II8, of the chute II2, is a trip arm. I24 that has its outer end, resting upon a spring stop I26 whichsis secured to a frame member I28. A tension spring I30 has one end'anchored to a side wall of the coin receptacle I06 and its other endtfo the trip arm I24 to normally hold the latter engaged with the stop I26, the arm I24 being provided with a bumper I32 to absorb the'shock incident to its engagement with the stop'j I26.
A shaft I34 is rotatively supported in bearings I36 mounted on a frame member I38 and carries a ratchet wheel I39 that is engaeedwitha pawl I40 ;.which is pivoted on a lever I42 having a hub I44, intermediate its ends, rotatively" mounted on-the"shaft"l34.- A second pawl I46 engages the ratchet wheel I39 and is pivotally mounted on a bracket I48 carried by a frame member I60. By this arrangement, counter-clockwise motion of the lever: I42 imparts a similar motion to'theratchet wheel I39 and, consequently,1to v the shaft I34,. thef second pawl I46 acting on the ratchet wheel" I38 to'prevent its clockwise motion.
{:A tension spring [52 has one end connected with thejlever I42 and its other end to avertical frame member I54. One end of a'cable I56 is attached tothe lever I42 and passes about a grooved pulley I58 supported from a side of-the foot support 80, as best shown in Figures 2 am 5, and downwardly therefrom for connection with a pin I60 carried by the channeled crosshead 60. A tension spring I62 has one end connected to the pin I60 and its other end anchored to the foot support 80. A buffiing wheel I64 is keyed on the shaft and extends partially 'throughIan opening I66 formed in the lower front wall 26, of the cabinet III, the extended portion of the buffer wheel and the opening being normally closed by a cover I68 that is hinged, as at I68,- to the adjacent side edge of the cabinet. v
.'I he electrical circuits of the machine, thus provided, are graphically depicted in Figure 6, and, as shown, lead-in conductors I12 and I14,
connects with one terminal I18 of the knife switch 98, the blade of which is adapted to engage with the terminal I18, when the rod 86 is depressed by the pressure of the footed shoe on the upper leg '88, of the spring 84, when the foot is resting on the support 80. A conductor I80 leads from the terminal I18 and connects a contact I82 of a manually actuated switch I10,
which may be of the snap type, and is mounted exteriorly of the inclined wall 24 of the cabinet I0. The other contact I84, of the switch I10, is connected by a conductor I86 to the other terminal I88 of the knife switch 98, which terminalis in electrical connection with the blade 96 and, by a conductor I90, with the other terminalof the motor -30.
In the operation of the machine, a coin is inserteddownwardly of the slot II4 (Fig. 2) and passes downwardly of the chute II2 towards its lower end where it establishes electrical connection between the conductor strips I22. At the same time, a foot is inserted inwardly of an open-.-. in: formed in the lower front wall 26 to position on the support 80, the said opening being nor-. mally closed by a hinged door I92. The toe re-' gion of the footed shoe, when properly-positioned on the support 80, engages beneath the bight 10' of the polishing web 62, and downward pressure of the heel of the shoe depressesthe upper leg 88, of the spring 84, and also the rod 86, causing the switch blade 86 to bridge the contacts I18, I88, of the knife switch 98, and close the circuit on=themotor 30. Motion of the rotor shaft 32, of the motor 30, is transferred to the crankshaft 50, the crank 52 of which impartsa reciprocating'motion to the arm 56 and through it to the web 62, when the bight portion of the latter will perform its polishing function, it being understood thatppri'or to the introduction of the footed shoefto the support 80, polishing material will have been applied to the shoe. The bight portion of the web 62 is permitted to act after the mam cover I68 is moved to open position for the ex:
posure of the protruding portion of the .bufling wheel 164, at the outer side of the lower front wall portion 26, so'that the foot can be manipuwhich may take the form of a conventional elec- I trical cord carrying a plug connector (not shown) for attachment to a wall or other power service outlet, pass to and respectively connect "with ,one ofthe conductor strips I22 and one terminal Of the motor 30. A conductor I16 leads from the other of the conductor strips I22 and latedto present these portions of. the shoe to the which shunts the line current about the knife switch 98.
: Continued operation of the motor:30 now actuates the lever I42 to effect rotation of the ratchet wheel I39 through one revolution, and, through it, the actuation of a coin release mechanism.
This mechanism is comprised in a trip I94 that.
is fixedly secured to the shaft I34 and lies in. the path of the spring stop I26. As the trip I94 engageswthe spring stop I26, the latter is flexed downwardly and, as the trip passes beneath the arm of the spring, the arm recoils and strikes the trip arm I24 and pivots the chute wall II8 away from. the front wall II6, ,thus spreading these walls at their lower ends and releasing the coin from between the contact strips I22. The
coin passes from the chute into the receptacle I06 and breaks the circuit on the motor 30. Access to the interior of the cabinet, below the storage compartment at its upper end, is to be had through two doors I96 hinged, as at I98 on the side walls I 4 of the cabinet Ill. The two doors I96 when in closed position form the rear wall of the cabinet l0.
Without further elaboration, the foregoing disclosure so fully illustrates my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. I 1
