SHOE-POLISHING MACHINE.

Specification of Letters Patent.

Patented Dec. 13, 1921.

Application filed December 10, 1919. Serial No. 343,775.

T 0 all whom it may concern:

Be it known that I, JosnPH HENRY KARP, a citizen of the United States, residing in the city of New York, borough of Manhattan, county and State of New York, have invented a certain new and useful Shoe- Polishing Machine, of which the following is a specification.

This invention is a shoe polishing machine, and, speaking generally, the object of the in.- vention is a machine of the character specified which will automatically polish shoes, and the like, in an expeditious, thorough, economical and generally eflicient manner.

Shoe polishing machines have heretofore been suggested, but their structures have been so complicated and their cost so excessive, which disadvantages, coupled with the inefficiency of operation of the machines, have precluded their commercial use..

Among the important features of the invention, though not the exclusive ones, may be mentioned the manner of mounting and operating the cleaning and polishing brushes, the means for automatically feeding the polishing material to the brushes, the mechanism for operating the brushes and associated devices and the manner of controlling, by means of a coin or similar member, the motor for driving the various mechanisms inherent in the machine as a whole.

The driving mechanism is preferably coin controlled, though thisjfeature, when the machine is used in certain environments may be dispensed with.

Features of the invention, other than those specified, will be apparent from the hereinafter detailed description taken in conjunction with the accompanying drawings.

In the accompanying drawings, I have illustrated different practical embodiments of the invention, but the construction therein shown is to be understood as illustrative only, and not as defining the limits of the invention.

In the drawings, Figure 1 is a plan View of the machine. I

Fig. 2 is a sectional side View; a

Fig. 3 is a sectional end view;

Fig. i is a plan View of the cam releasing and electric switch mechanism;

Fig. 5 is an end view of the mechanism shown in Fig. 4;

Fig. 6 is a plan view of a modification of the machine; and, I

Fig. 7 is an end view of said modification.

Referring to the drawings, 1 is a casing within which the operating mechanism is housed, and 2 a coin box of any desired mechanical type, having a shaft v3 extending downwardly through the top of casing 1 to a bearing bracket l. Keyed to shaft 3 is a rocker arm on which is mounted a releasing pawl 6. The bearing bracket 4 carries a cam 7 upon which the releasing pawl 6 rides, and which releases a rocker arm 8 through the medium of pin 9, for the purpose herein after described. Arm 8 is loosely mounted upon shaft 3 and is returned to'its original position by means of a suitably mounted spring. A connecting rod 10 connects the arm 8 .with a stop pawl 11 supported on bracket 12, see Fig. 2, the end of which pawl rides on a stop cam 19 Pin 13, carried by the connecting rod 10, actuates the electric switch pawl 14: which has integral therewith the bus-bar 14: of the electric switch 15.

The electric switch pawl 14: is supported by a bracket 16. An arm 17 which is keyed to electric switch pawl 14L rides on the switch releasing cam 18 for thatpurpose. .A shaft '20 which is free to rotate in bearings 21 and 22, see Figs. 2 and 3, has keyed thereon a worm wheel 23, a cam 24;, the stop cam '19, the switch releasing cam 18and a foot operating cam 25.

A worm 26, meshing with the worm wheel 23, is keyed on shaft 27 its bearing being part of the bearing 21. -The opposite end of shaft 27 has positioned thereon a gear 28 which meshes with a spur gear 29 on the "drive shaft of electric motor 30. A lever 31, carried by a pivot bracket 32 has thereon a cam roller 33 which-rides on cam 24%. A push rod 34, supported in bearings 35 is connected to lever 31 by means of a pin 36 which operates in the slot 36 formed in one end of said lever, the purpose of which is to prevent undue friction or binding incident to the movement of said lever and push rod. A spring 37 is fastened to the end of lever 31 in order to keep the roller 33 in engagement with the cam surfaceof thecam 24:, and which also serves the function of pulling push rod 34 back with it.

Pawls 38 arein mesh'with ratchet gears I 39, which have a female screw threaded portion to fit the screw threaded stems on the plungers 40. These plungers, as clearly appears from Fig. 2, operate in the bottle containers 41 may be filled with the paste by moving the screw plug 41, said containers having distributers 42 attached thereto, which serve to deliver the paste to v the brushes 58. Containers 41, plungers 40, and ratchet gears 39 are supported by brackets 43. A bracket 44 has pivoted thereto a lever 45, and the latter carries a cam roller 46, which is actuated by the cam 25. V The lever 45 is slotted on one end in order to allow a free forward movement of a foot piece 47 to which it is attached, said foot piece having sliding movement in the grooved portion of a bracket 48 for that purpose.

The shaft of motor 30 has mounted thereon' a bevel gear 49, meshing with bevel gear 50, which drives a pinion gear 51, both of which latter gears are keyed to shaft 52. Pinion gear 51 meshes with a gear 53 on a shaft 54, which, in turn, meshes with gears 55 which are centrally pivoted about the gear 53 by means of pivot arms 56. Shaft 57 to which the gears 55 are keyed runs freely in the pivot arms 56, the upper ends of said shafts having attached thereto polishing brushes 58.

The shafts or spindles 57 are thus supported by the arms 56 for. bodily pivotal movement about the common axis of the shaft 54 and are preferably normally impelled in a direction toward the shoe support 47 by means of a pair of springs 56 shown best in Figs. 2 and 7. Each of'the springs 56 is-secured to one of thelower arms 56 at one of its ends and at its other end is anchored the upstanding web which supports the bracket 48 of the shoe support. The brushes will accordingly be automatically maintained by the springs 56 in a position to cotiperate with the shoe resting upon the support 47, but said springs will permit the brushes to retract slightl to compensate for shoes of different sizes and to permit of variations in the longitudinal cross sections of the shoe as the shoe is moved back and forth between said brushes during the polishing operation. 7 7 r n Figs. 6 and 7, which show a modification of the invention, like numerals represent like parts in Figs. 1, '2, 3, 4 and 5. In this modified construction, a collar 59 is inserted between the cam 25 and the cam 24 as a substitute for theswitch throw out cam 18 and the stop cam 19 and an electric plug 60 and wire 61 are employed instead of the construction as described From the foregoing description of the mechanism, its operation w ll be readily understood, but it maybe described briefly, as'follows Y ,When it is desired to operate the machine,

' acoin of predetermined denomination is in- The coin makes a mechanical connection with the operating parts in said box thereby permitting shaft 3 to be rotated by the hand lever 2., said'shaft acting upon the arm 5, pulling the arm 8 backward, thus releasing the pawl 11 from the cam 19. During the 7 drives the worm wheel 23, mounted on the shaft 20. Cam 25 being fast on the shaft 20 will also rotate, and the cam action of said cam upon the roller 46 will pull the lever 45 backward moving the foot piece '47 forwardly between the brushes 58. The cam 24 has also come into action, being on the same shaft, with the worm wheel, the surface of which acts on the roller 33 pushing the lever 31 in such direction that the action of the pawls 38 on the ratchet gears39 will advance the plunger 40 upward by means of the screw threaded stems 39 thus forcing the polishing paste through the. distributors 42 upon the surface of the brushes 58. These brushes are rotated when the motor 30 is operated, through the medium of the train of gears 50, 51, 53 and55. The brushes 58 being pivotally mounted on arms56, and being under light spring tension, operate with uniform pressure upon the shoe, as the foot supporting member 47 reciprocates between them. The cam 25 makes one complete revolution to shine both shoes; there being a pause or dwell in the cam action to allow for the shiftbackward, whereupon the connecting rod 10 is pulled forward. Thepin 13 will then be retracted from the electric switch pawl 14', allowing the lever 17 to which it is attached to be thrown outward by the action of the cam 18, thus breaking the circuit and stopping the machine.

To operate the modified form of machine,

shown in Figs. 6 and 7, the plug 60 on elec-.

tric wire 61 is screwed into an electric socket. The switch is turned on, whereupon the machine will operate continuously until the switch is turned off manually. V

It will be understoodthat the specific invention described may be modified in formal respect, such as by the substitution'of equivalents and that parts of the complete mechanism described may be used alone, or in other environments, without departingffrom the spirit or substance of the broad invention, the scope of which is commensurate with the appended claims.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

1. In a shoe polishing machine, a foot support, a pair of rotatable brushes mounted for swinging movement toward and away from the foot support, means for yieldably moving the brushes toward said support, a prime mover, gearing connections between the prime mover and the brushes for imparting rotation to the latter, a cam also operated by the prime mover, and a pivoted rocker arm secured to the foot support and cooperating with the cam, whereby the foot support is reciprocated between the brushes while the brushes are rotated.

2. In a shoe polishing machine, a foot support, a pair of rotatable brushes mounted for swinging movement toward and away from the foot support, means for yieldably moving the brushes toward said support, a prime mover, gearing connections between the prime mover and the brushes for imparting rotation t the latter, a cam also operated by the prime mover, and a pivoted rocker arm secured to the foot support and cooperating with the cam, whereby the foot support is reciprocated between the brushes while the brushes are rotated, in combination with means, automatically operated by the prime mover, to supply polish to the brushes.

3. In a shoe polishing machine, a foot support, an upstanding spindle, a pair of brushes, arms pivoted to the upstanding spindle and carrying the brushes and means associated with the arms for impelling the brushes toward one another, in combination with an electric motor, operative connections between the motor and the brushes for imparting rotation to the brushes, and additional operative connections between the motor and the foot support for reciprocating the latter to and fro between the rotating brushes.
