THE AUTOMATIC ELECTRIC SHOE POLISHIN'G MACHINE COMPANY, OF BRYAN, I

TEXAS, A CORPORATION OF TEXAS.

SHOE-POLISHING MACHINE.

Application filed December 7, 1920. Serial.No. 428,991.

T all whom it may concern:

Be it known that I, CLIFFoRn A. HARRIS, a citizen of the United States, residing at Bryan, in the county of Brazos and State of Texas, have invented a certain new and useful Improvement in Shoe Polishing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to apparatus for cleaning and polishing shoes, and is primarily concerned with a paste feeding mechanism adapted to be operated by a; coin controlled means, which governs the operation of the cleaning and the polishing mechanism. My invention as relating to the novel paste feeding mechanism is well adapted for use in connection with such a polishing machine as shown and described in the copending apconsistency and degree of adhesiveness thereof.

Anot'herobject is the provision of simple and effective mechanism for causing the operation of the paste feeding means, which mechanism is adapted to be governed by a coin controlled mechanism.

In this machine the whole operation results automatically from the operation of an electric motor,the circuit of which is closed by the deposit of a coin, this motorreciprocating the brushes and paste feeding mechanism and the latter being actuated, consequent upon such reciprocation. means for effecting the reciprocation and for terminating the operation are included within my invention.

The means for effecting the positive feeding, and for carrying out the other operations -referred to, willbe fully set forth-in the following description, which relates to the paste.

The

the drawings, and the essential novel characteristics thereof will be set forth in the claims.

In the drawings, Fig. 1 is an elevation in the natureof a section thru a polishing mach1ne,.embodying the features of my inventlon; Fig. 2 is a plan of the machine having the cover thereof removed; Fig. 3 is a section thru the machine taken on the line 33 in Fig. 1; Fig. at is a fragmentary view showing an elevation of thepaste feeding mechanism; Fig. 5 is a plan of the mechanism, adapted for reciprocating the polishing brushes; Fig. 6 is a section of the paste container; Fig. 7 is an end View showing the method of supporting the orifice-end of the The front of thiscasing supports a stool 11 for the customer, while at the rear is an. elevated portion 14 adapted to house the op- -erating and controlling -mechanism. The

brushes and paste carrier are suitably supported on a carriage 15, having wheels 16, which travel on a trackway 17.

The motor 12 is shown in Fig. 1 as connected thru suitable gearing to a shaft 18, i

which shaft may be supported at one end by a bracket 19 and at the other end by brackets 20, 21, carried by the carriage 15. I have shown. beveled gearing 22, for transmitting rotary motion from the shaft 18 to the shaft 28 on the carriage. This latter shaft is suitably geared for rotating a vertical shaft 23 to operate the vertically disposed'brushes 13. The horizontally disposed brushes24 are adapted to-be rotated thru a sprocket chain 25, connected with a sprocket wheel on a shaft 26, which in turn may be driven by a sprocket chain 27 from a shaft 28.

To reciprocate the carriage, I have shown in Fig. .5 a worm 29. mounted on the shaft 26, and engaging a worm wheel 30. This worm wheel is supported by a shaft 31 in a bracket 32, which bracket may constitute a part of the carriage 15. Extending from the lower end of the shaft 81, I provide a crank arm 83, which is connected to a block 34, which block is adapted to slide in a.

container 39, mounted on the carriage 15.

This container is shown as supported at one end by a clamping member 36, carr ed by .a bracket 37, on which bracket the horizontally disposed brushes24 are mounted. The.

other end of the paste feeding container is positioned by a stirrup 38, which may also be carried by the .bracket 37. As the car-. riage is reciprocated, the paste feeding .mechanism is therefore moved siun1ltaneously therewith, so that the discharge end of the feeding mechanism is adjacent the vertical brushes onto which the paste is tobe deposited.

The container 39, which is adapted to retain a mass of paste, is provided with a piston 40, which moves in the container and longitudinally thereof. A continuously threaded rod 41 extends thru the container and co-operates with the piston to move it within the container. for rotating the plunger rod, at periodic n-. tervals, to eject a predetermined quant ty of paste from the container, will be hereinafter described. I i

The container 39 preferably comprlses a cylindrical member, equipped at one end with a removable cap 42, and provided at the other end thereof with a tapered orifice member 43. The tapered member 43 is adaptedto extend from an aperture 44, in the stirrup 38, and to be held thereagainst by a spring 45, which bears againstthe cap42.

By virtue of' the close fitting engagement between the piston and the walls of thecontainer, I provide a positive feed of the paste against the brushes 18. To prevent the plunger 40 from. rotating within. the container, I provide a gulding member or strap 46 secured to the inner surface of the container and occupying a groove in the piston. The piston rod 41 is supported at 47, by the cap 42, and is equipped at the extreme inner end thereof with a spring 48, and a collar 49. This spring serves as a yielding member against which the piston may abut wheni ever it reaches the end of the feeding stroke.

That portion of the rod on which the yielding member is mounted is not threaded, and the piston may therefore ride onto that portion without endangering the threads on the rod, or, causing jamming.

To enable the container to be removed from its support for refilling, and at the Suitable mechanisnr masses same time to permitthe' plunger rod to be effectively rotated, I provide, as shown in Fig. 6, an interengaging connection between the plunger rod and its operating shaft 50.

.This interengaging connection may comprise a sleeve 51, yieldingly mounted on the rod 41. This sleeve may be provided with one or more slots, which extend from the end '52 thereof and are of a size sufficient to permit the pins 53, 54, to be inserted therein. Thepin 53 is rigidly connected with the rod 41, while the pin 54 is rigidly supported on the shaft 50, and consequently whenthe container is in operative position, the sleeve 51 is normally held in engagement with the pin 54, and a positive drive is therefore effected between the drive shaft and the plunger rod. The simple movement of the sleeve toward the container releases the connection. In a number of containers are shown in position upon the carriage 15, and the operating mechanism for each container is shown as constituting a shaft on which are mounted the beveled gears 56, coacting with gears 5.7, mounted on the drive shafts 50. lit will be understood, therefore, that each ,piston is simultaneously operated to eject a mass of paste against the respective brushes. To operate the shaft 55, T provide a ratchet wheel 58, as'shown in Fig. 9, and it provide a pawl 59, which co-operates with the ratchet wheel to rotate the shaft 55, and thereby cause the feeding operation.

In Fig. 12 the feed ratchet wheel 58 is.

shown as rigidly connected with the shaft 55 and ad a-cent the bearing block 60. This bearing block may constitute the end of a standard 61, which projects upwardly from the carriage '15, and is, therefore, adapted to be recip'rocated therewith. Adjacent the feed ratchet wheels, I provide another ratchet wheel, which will be designated the master wheel 62. This master wheel controls the feeding and stopping mechanism in a manner that will be now described.

Toactuate the master ratchet wheel, I provide,; as shown in Fig. 4, a pawl 63, pivoted at- 64, to a bracket'65, which bracket may be rigidly secured to the casing 10. A spring 66 normally urges the tootlrof the pawl 63 upwardly, and enables it to engage a tooth in the master wheel when the carriage is in its rearmost position. This rearmost position is shown in Fig. 1 and also. in Figs. 8 to 11. Whenever, the wheel is engaged by the pawl, it is advanced a distance the number of the reciprocations.

I have shown the master wheel having twelve teeth, one of whichas at 67,'is cut deeper than the other teeth. When the pawl 63 drops into the tooth 67 then the nose of van'ce it. I

gage the lowermost portion of an arm 68. This arm is loosely mounted on the shaft 55 intermediate the ratchet wheels 58 and 62 and carries a pawl 59. This pawl is pivoted at 69 and is normally held against the feed ratchetwheel 58 by a spring 70. The upper end of the arm 68 may be attached to the endof a spring, as at 71, the other end of the spring being secured, as at 72, to the bearing block 60. The face of the pawl 63 possesses sufficient, width to permit one side thereof to engage the notched end of the arm 68, whenever the nose of the pawl drops into the tooth 67. This causes a feeding of the aste on one stroke of the carriage. en the pawl 63 is in contact with any .of the teeth of the master ratchet except the deep tooth 67, it is adapted to clear the arm 68 and to cause only the master wheelto be advanced one notch. Such a condition .is shown in Fig. 10, wherein the pawl is .about to engage the master wheel andi to ad- To regulate the-flow of paste from the container, I provide adjustingmechanism comprising preferably an adjusting screw 73, supported in the bearing block 60 and equipped with a lock nut 7 4. The retaining g'pring, attached to the upper end of the arm 68, urges the portion 7 5 thereof against the lower end of the adjusting-screw, so that it is possible toregulate the number of teeth to be engaged by the pawl 59 by manipulation of the adjusting screw 73.

In operation, assuming that a coin 76 is inserted in a coin chute 7 7 then the circuit is completed between the contact points 78, 79, and the motor 12 is-set in operation. Due to the mechanism heretofore described, the carriage 15 is caused to reciprocate on the trackway 17, 'and.the master ratchet wheel 62 to engage, nearthe end of its rearward stroke, with the pawl 63, carriedby the stationary member 65. A further rearward motion 'of the-carriage causes the master wheel to be advanced one notch, and when the pawl engages the tooth 67, then the arm 68 is moved, simultaneously with the wheel 62. Movement of the arm 68 causes the feed ratchet 58 to be rotated. The shaft is rotated with the ratchet wheel 58, which motion is transmitted thru the gears 56, 57-, to the plunger rod 41 to cause the piston to move inwardly within the container and thereby to eject a predetermined uantit of paste.

During the cycle of operation. above described, the coin 76 remains betweeirthe contact point 78, 79. To remove the coin from this position and to bring the operat ing mechanism to a stop. I provide a pin 80. which pro ects outwardly from one side of the wheel and is adapted to be engaged by 'Fig. 1, while the bell crank may be. connected-by suitable mechanism to a lever 85, on which the contact point 79 is mounted.

This system of levers and 'links is so arranged, that rearward movement {of the lower part of the arm 82, causes the lever 85, carrying the contact point 79, tobe oscillated, whereby the'coin 76 is dropped into a suitable receptacle, and the current is cut off from the motor 12, stopping the machine. 1 The pin 80 which determinesthe point of stopping and starting, is so positioned-on the master wheel, that one or more reciprog motions of the carriage must ensue e, the paste feeding operation occurs. rovides for cleaning the shoes of a cati "customer prior to the application of paste and subsequent polishing operations.

To refill the container 39, the operator unclamps the yoke 36, which yoke is constructed in two parts, one hinged upon the other, as at 86, and clamped preferably by a winged nut, as at 87. He then moves the sleeve 51 toward the container against tension of the spring 45 until it is disengaged from the pin 54 and the end 52 thereof clears the end of the shaft 50, thereupon the container may be tilted about the aperture 44 in the inner supporting bracket 38 and the entire container moved rearwardly and lifted from the machine. The cap 42 may then be removed and the filling operation quickly accomplished. The piston is then spun back-on the threaded rod and re-inserted in the casing. The container is then inserted in the machine'whereupon the latter is ready for continued use. a

From the foregoing description it will be seen that I have provided apaste-feeding mechanism that is capable of operationirrespective of the consistency of paste to be applied; that I have provided a feeding mechanism which may be conveniently ad'- justed to regulate the quantity of paste to be ejected, and that my paste feeding mechanism is well adapted for use with a polishing mechanism having a carriage reciprocated under the control of a deposited coin.
