3 Claims.

My invention relates to shoe shining facilities, and has among its objects and advantages the provision of an improved shoe shining machine embodying a coin controlled electric circuit for setting the motor in operation upon insertion of a coin of predetermined denomination.

In the accompanying drawings:

Figure 1 is a front elevational view of a machine in accordance with my invention;

Figure 2 is a sectional view taken along the line 2-2 of Figure 1;

Figure 3 is a rear view portion broken away for the purpose of illustration;

Figure 4 is a sectional view taken along the line 44 of Figure 2;

Figure 5 is a sectional View taken along the line 55 of Figure 4;

Figure 6 is an enlarged sectional view taken along the line 66 of Figure 3; and

Figure 7 is a diagrammatic view of the electric circuit.

In the embodiment selected for illustration, I make use of a cabinet IB- having a frame structure I2 to which are secured side walls I 4 and mounted on caster wheels I6. The top structure of the cabinet includes a chamber I8 for contain ing shoe polishes and polish applying brushes and the like. Two doors 20 are hingedly connected to the front wall section 22. The front of the cabinet includes an intermediate inclined wall 24 and a lower wall 26.

Inside the cabinet It and upon its floor 28 is mounted an electric motor 30 having its rotor shaft 3'2 provided with a small grooved pulley 34 for driving a V-belt 36. Belt 36 passes around a, somewhat larger grooved pulley 38 keyed to a line shaft 48 supported in bearings 32 mounted on the floor 28. A second small grooved pulley 44 is keyed to the line shaft 40 for connection with a V-belt 46 passing over a large grooved pulley 48 keyed to a shaft 50 having a crank 52 formed therein. Shaft 59 is rotatably journaled in posts 54 secured to the floor 28.

An arm 56 has a bearing 58 connected with the crank 52 and is provided with a channeled crosshead 60' at its opposite end within the channel of which is fixedly connected one end of a shoe shining cloth or web 62. Web 62 extends upwardly from the channel 60 and is supported intermediate its ends by elastic straps 64 and Ma, the former being hooked over ends 66 on a horizontal frame member 68 located above the footstand BI], and the latter being connected to a frame member 6B located forwardly of the footstand. To the depending run I0 of the cloth 62 is secured a plurality of elastic straps 12 having .2 their ends clamped between a plate I l and the floor 28 through the medium of bolts I6.

The cloth 62 is of U-shaped configuration, when viewed according to Figure 3, with its bight I8 of sufficient length to provide room between the two vertical runs of the belt for easy entrance of the shoe being polished. One of the straps 64 is secured at its lower end to the bight 18 at the transverse center of the bight and near the rear edge thereof. The remaining straps 64 are secured at their lower ends to the bight near the rear edge of the bight and the sides of the web 62. These straps normally support the rear edge of the bight l8 sufiiciently above the footstand and in such manner as to enable the shoe to be conveniently placed 0n the footstand within the bight. The strap 64 which is secured to the bight 18 at the front edge of the bight, supports the front edge of the bight slightly above the footstand 80 and normally prevents the rearward displacement of the bight with respect to the footstand.

The footstand or stool 80 is secured to the lower wall 26 and one of the posts 54, which stool is arranged substantially horizontally and eXtends underneath the bight I8 of the polishing cloth. Upon the heel margin 82 of the stool 8D is mounted a U-shaped spring 84 having one end of a rod 86 engaging the uppermost leg 88 of the spring 84, the leg 98 of the spring being provided with an opening 92 through which the rod 86 extends loosely. The rod also extends loosely through an opening 94 in the heel margin 82 and extends downwardly for connection with the blade 96 of a knife switch 98 mounted on the floor 28.

One end of a tension spring I00 is connected with a pin I 02 attached to the rod 86 and the other end of the spring is connected with a pin I04 attached to the bottom wall 26. Spring I00 exerts a pull on the rod 86 when pressure is released from the spring 84 for opening the switch 98.

Inside the cabinet II] is mounted a coin box I86 having a hinged bottom Hi8 which may be-locked in its closed position by inserting a padlock through the hasp I10. A coin chute I I2 has communication with the coin box I66, and thewall 24 is provided with a coin slot IIII through which a coin may be inserted.

Coin chute H2 includes front and rear walls H6 and II8, respectively, located between side walls I20. The walls of the coin chute are formed of insulative material, and the rear wall II8 is hingedly connected at I22 with the wall 24. To each of the Wall H6 and II8 is secured a conductor I22. Figure 6 illustrates the normal relative positions of the conductors I22, wherein the conductors converge downwardly so as to be slightly spaced one from the other at their lower ends. The spacing is such that when a coin, such as a one-cent piece, is dropped into the chute II2, the coin will electrically bridge the conductors I22.

To the wall H8 is fixedly secured a trip arm I24 having its-outer end resting on a spring stop I26 in the nature of a strap having one end fixedly secured to a frame member I28. A tension spring I30 has one end anchored to the coin box I06 and its other end secured to the trip arm I24 for holding the latter in engagement with the spring stop I26, the arm I24 being provided with a bumper element I32 contacting the spring stop.

A shaft I34 is rotatably supported in bearings I36 mounted on a frame member I38, and a ratchet wheel I39 is secured to the shaft I34 and is engaged by a pawl I40 pivoted on a lever I42 having a hub I44 intermediate its ends rotatably mounted on the shaft I34. A second pawl I46 engages the ratchet wheel I38 and is pivotally mounted on a bracket I48 mounted on a frame member I50. Thus counter-clockwise rotation of the lever I40, when viewing Figure 6, imparts similar rotation to the ratchet wheel I38, and the ratchet wheel is restrained from clockwise rotation by reason of the pawl I45.

A tension spring I52 has one end connected with the lever I42 and its other end attached to a vertical frame member I54. One end of a cable I56 is attached to the lever I42 and passes around a grooved wheel I58 attached to the stool 80, see Figures 2 and 3, and downwardly for connection with a pin I60 attached to the channel 60. A tension spring I62 has one end connected with the pin I60 and its other end anchored to the stool 80. 1

To the shaft 40 is secured a bufilng wheel I 64, the wall 26 being provided with an opening I66 normally closed by a cover I68. Wheel I64 extends partially through the opening I66. A switch I10 is mounted on the wall 24.

Figure '1-illustrates the electric circuit, wherein the wires I12 and I 14, which may be in the nature of a conventional electric cord adapted to be plugged into a wall socket, respectively lead to one of the conductor strips I22 and the motor 30. A wire I16 connects with the other conductor I22 and with a terminal I18 of the switch 98, the blade 96 being adapted for engagement with the terminal I18 when the rod 86 is moved downwardly. A wire I80 connects the terminal I18 with a contact I82 of the switch I10, the contact I84 of this switch being connected with a wire I86 electrically connected with the terminal I88 to which the blade 96 is also connected. A wire I90 leads from the terminal I88 to the motor 30.

In operation, a coin is dropped into the chute H2 and the toe portion of the shoe, while on the foot of, the wearer, is placed on the stool 80. A hinged door I92 provides accommodation for the foot when placed in position on the stool. The toe region of the shoe fits snugly within the bight 18. As heel pressure is applied to the spring 84, the rod 86 is pressed downwardly for closing the switch 98 to energize the motor 30, since the coin bridges the two conductors I22. Energization of the motor 30 imparts rotary motion to the crank 52 for drawing the polishing cloth 62 back and forth on the toe region of the shoe. The elastic straps 64 and the straps 12 yield to accommodate reciprocatory motion of the arm 56 4 connecting the polishing cloth I56 with the crank 52.

Continued operation of the motor 30 actuates the lever I40 for rotating the ratchet wheel I38 one revolution. To the shaft I34 is fixedly secured a, trip I94 arranged in the path of the spring stop I26. As the trip I94 engages the spring stop, the latter is flexed downwardly, and as the trip passes beneath the spring arm, the spring arm recoils and strikes the trip arm I24 for pivoting the wall II8 away from the wall II6, thereby releasing the coin lying in engagement with the two conductors I22 for breaking the circuit through the motor.

When polishing the sides and back portions of the shoe, the cover I68 is moved to an open position for exposing the buffing wh'eel I64, so that the shoe may be manipulated about the bufling wheel for polishing purposes. When employing the bufiing wheel I64, the circuit is closed through the motor 30 through the medium of the switch I 10 so that the motor may be operated independently of the switch 98.

The rear wall structure of the cabinet I0 comprises two doors I96 hinged at I98 to two corners of the cabinet. The doors I96 lend access to the interior of the cabinet.

Without further elaboration, the foregoing will so fully illustrate my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service.
