WWNMNON NNM ted tes This invention relates to shoe polishing stands of the type generally referred to as automatic in that upon depositing a coin in a slot brushes or other devices are operated to polish shoes positioned on shoes receiving plates of the machine.

The purpose of this invention is to provi-de a shoe polishing machine in which, with the shoes of a customer positioned upon the plates in the machine polishing material is sprayed on the shoes and the shoes are brushed upon depositing a coin in a slot.

Various types of shoe polishing machines have been provided, however with the conventional type of machine it is difiicult to polish the forward and rear portions of the shoes at the same time. With this thought in mind this invention contemplates a shoe polishing machine having brushes positioned to reciprocate laterally across the forward portions of shoes with additional brushes positioned to travel longitudinally over the rear portions of the shoes and with spray nozzles positioned to deposit polishing fluid upon both the rear and forward portions of the shoes.

The object of this invention is, therefore, to provide means for operating shoe polishing brushes whereby some of the brushes reciprocate laterally in relation to the shoes and others longitudinally of the shoes. i

Another object of the invention is to provide a shoe polishing machine in which upon insertion of a coin in the machine a polishing liquid is sprayed with compressed air over both the forward and rear surfaces of shoes, positioned in the machine.

A further object of the invention is to provide an improved shoe polishing machine which is of a comparatively simple and economical construction.

With these and other objects and advantages in view the invention embodies a shoe polishing machine having a substantially box-like housing with an upright portion having a coin slot therein and also havingy a polishing liquid tank in the upper part thereof, a seat positioned whereby a customer positioned on the seat may place his feet through openings in the upper surface of the lower part of the stand, and motor actuated instrumentalities in the lower part of the stand for laterally reciprocating brushes across the forward parts of the shoes and for longitudinally reciprocating brushes over the heels of the shoes.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Referring now to the drawings wherein like reference characters denote corresponding parts the shoe polishing stand of this invention includes a box-like housing having a base 10 with side walls 11 and 12, end walls 13 and 14 and an upper panel 15, a seat 16 positioned on the panel 15, an upright section 17 in which a coin slot 18 and a polishing liquid tank 19 are positioned, brushes 2@ and 21 f-or polishing the forward parts of shoes, brushes 22 and 23 at one side of the machine for polishing heel of a shoe and similar brushes 24 and 25 in the opposite side of the machine, plates 26 and 27 positioned to coact with the brushes, spray nozzles 28 and 29 at the front and 36 and 31 at the rear, and a motor 32 for operating the parts.

The motor 32, which is mounted on the base 1@ is provided with an extended cam shaft 33 which is operatively connected to a transversely disposed shaft 3ft with beveled gears 35 and 36 and the opposite end of the shaft 34- is operatively connected to a shaft 37 with gears 33 and 39.

The shafts 33 and 37 are provided with eccentrics 40 and 41, respectively and, as illustrated in Fig. 2, the cams or eccentrics 4t) and il are positioned to engage vertically disposed arms 42 and i3 which are connected to the brushes 20 and 21, respectively with L- shaped brackets 44 and 45. The arms 42 and 43 are carried by rods 46 and 47 slidably mounted in bearings S8 and 49 and the rods are resiliently held with the arms 42 and 43 in extended positions against the small radius of the cams with springs 50 and 51, respectively. The inner ends of the rods 46 and i7 are provided with heads 52 and 53 and the heads are positioned to engage resilient elements 54 and 55, By this means as the shafts 33 and 37 are rotated by the motor the cams di) and 41 rotate forcing the arms 42 and i3 inwardly toward the center of the machine from the position shown in Fig. 2 whereby the brushes Ztl and 21 are reciprocated laterally across shoes positioned upon the plates 26 and 27.

During this movement the shaft 34 rotates an eccentric shaft 56 through gears 57 and 58 and also an eccentric shaft 59 through gears 60 and 61. The shaft 56 is mounted on the base 10 with bearings 62 and 63 and the shaft 59 is also mounted on the base with a bearing 64.

Discs 65 and 66 with pins 67 and 68 eccentrically positioned therein are mounted on the shaft 56 and a similar disc 69 with a pin 70 eccentrically positioned therein is mounted on the shaft 59. With the parts positioned in this manner the eccentric pins are positioned to engage levers 71, 72, and 73 which are pivotally mounted with pins 74, 75 and 76, on the base 10.

As illustrated in Fig. 6 the lever 71 is engaged by the pin 68 on the disc 66 and upon engagement of the lever 71 with the pin 68 the lever, in cooperation with the levers 72 and I3 slides shoes or blocks 77 on bars 7S of a frame including side bars 79 and 80, to which the ends of the bars 78 are connected and which is supported from the base 10 with posts 81 and 82.

The sliding blocks 77 carry the brushes 22 and 23 at one side and 24 and 2S at the other, the brushes being mounted on the blocks with bars 83 and resiliently held from the shoes with springs Se, as shown in Fig. 4.

The upper ends of the levers 71 are provided with slots 8S into which pins Se on the blocks 77 extend, as shown in Fig. 6 and the levers 71 are urged toward the retracted position as shown in Figs. 3 and 6 with springs S7. By this means the heel polishing brushes 22, 23, 243, and 25 are actuated by the shaft 3e whereby the brushes are reciprocated over heels of shoes on the plates 26 and 27.

The shaft of the motor 312 is also provided with an erf;- tension 8S, which extends from the end of the motor opposite to that from which the shaft 33 extends and the extension 8S is provided with a compressor S9 through which air, drawn through an intake 9b in an opening 1 of the end wall 11, is supplied to the upper end of the tank 19 to which the compressor is connected with a tube 92. By this means air under pressure is provided in the upper end of the tank 19 and when a ball valve g3 is actuated by a solenoid 941 polishing liquid in the tank 19 is sprayed, under pressure7 from the nozzles 28, 29, 3l? and 31 upon shoes on the plates 26 and 27.

The ball valve 93 is positioned to Contact a seat 95 in the lower end of the tank 19 and the valve is urged to the closed position with a spring 96. The spring 96 is positioned in a tube 97 extended from the tank 19 and the lower end of the tube is connected by a tube 98 to a header 99, on the ends of which the nozzles ..18 and 29 are carried, and to a header 1th) on the ends of which the nozzles 3@ and 31 are positioned. The tank 19 is provided with a tilling plug 161 and a safety relief valve 192.

The upright section 17 of the housing is provided with a cover 103 that is secured to the housing with a hinge 104, and as illustrated in Fig. 4 the lower part of the housing is provided with a door 1% that is secured to the housing with hinges 141e, at one side, and with a lock, as indicated by the numeral 107 at the opposite side.

The coin slot 18 is formed, as illustrated in Fig. 5, with an inclined section that leads into a straight section 19d and from the section 168 coins drop into a coin pan 109.

The section 1133 of the coin chute is provided with an opening 111% through which a contact arm 111 that is pivotally mounted on the chtite by a pin 112 extends. The contact arm is positioned to engage a contact 113 as it is moved from the position shown in `full lines in Fig. to the position shown in dotted lines whereby a circuit is completed between wires 11d and 11 The wire 114- extends to an electric cord plug 116 and the other Wire from the plug, which is indicated by the numeral 117 extends to the motor 352 being connected d1'- rectly to one terminal of the motor. The other terminal of the motor is connected by a wire 118 to the wire 115 which extends from the contact 113. By this means a circuit is completed to the motor as a coin, as indicated by the numeral 119 moves the contact arm 111 against the contact 113.

The motor 32 rotates a Contact disc 121) whereby a contact 12.1 of the disc moves from the position shown in Fig. 8 to that shown in Fig. 9 whereby the contact member engages a brush 122 which is connected by a wire 123 to the solenoid 94 whereby a circuit is completed to the solenoid and the solenoid raises the stern 124 of the ball valve 93 so that shoe polish is discharged through the nozzles upon shoes on the plates 26 and 27. The circuit through the solenoid is completed with the parts as shown in Fig. 9 wherein one terminal of the solenoid is connected by the wire 123 to the brush 122 which is in contact with the member 121 that engages a contact ring 125. The contact ring 125 engages a brush 126 which is connected to the wire 114 with a wire 12 whereby the circuit is completed to one side of the plug 116. The circuit from the other side of the plug Vis connected to the opposite terminal of the solenoid 94 by a wire 12S which is connected to the wire 117. rl`his circuit is completed only,

for an instant, at which time liquid polish is sprayed upon shoes on the plates 26 and 27.

As the coin leaves the position shown in Fig. 8 it releases the contact arm 111 whereby a spring 129 returns the Contact arm to the position shown in full lines in Fig, 5 with the arm breaking the circuit to the contact 113 in the motor. For this reason the contact disc is also provided with a ring which has an insulated section 131 therein upon which a brush 132 rests with the parts in the position shown in Fig. S, however, as the disc is rotated the insulated section 131 leaves the brush 132 whereby a circuit is completed to the motor with the brush 132 connected to the wire 118 with a wire 133 and with the brush 126 connected to the wire 114 with the wire 127. The brush 126 engages the ring 125 and the ring 125 is connected to the ring 130 with the contact member 121 whereby the motor circuit extends from the plug 116 through the wire 114 to the wire 127 and from the brush 12e to the ring 125, through the member 121 to the ring 13u, and from the ring 13@ through the brush 132, Wire 133, and wire 11S to one terminal of the motor, the opposite terminal of the motor being connected to the plug 116 with the wire 117.

The motor circuit will remain completed until the disc 120 makes a complete revolution at which time the insulating section 131 engages the brush 132 to break the circuit. At this time the parts are in the position as illustrated in Fig. 8.

The disc 120 is rotated from the shaft 137 With a worm 134, on the shaft 37 and the worm meshes with the worm gear 135 on the shaft 136 on which the contact disc 120 is mounted, as shown in Fig. 4.

Operation With the parts mounted and actuated in this manner a coin dropped into the chute 18 closes a circuit to the motor and solenoid whereby liquid polish from the tank 19 is sprayed with compressed air over shoes positioned on the plates 26 and 27 and as the operation of the motor continues the cams 40 and 41 reciprocate the frames 44 and 45 on which the brushes 20 and 21 are carried whereby the brushes travel laterally across the forward parts of the shoes. At the same time the gears on the shaft 3d, as illustrated in Fig. 7 actuate the eccentric levers 71, 72 and 73 whereby the brushes 22, 23, 24, and 25, carried by the shoes 77 on the bars 7 8 are reciprocated longitudinally of the shoe carrying plates whereby the brushes travel over the rear portion of the shoes. By this means the shoes are completely polished and after the disc 121) makes one complete revolution the circuit is broken to the motor and the contacts set whereby upon the insertion of another coin in the chute 1S the cycle of operations will be repeated.

1t will be understood that modications within the scope of the appended claim, may be made in the design and arrangement of the parts without `departing from the spirit of the invention.
