To (1f/J. whom t may concern:

Beit known that I, ROBERT O. HAMMOND, acitizen of the United States, residing a't Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Slice-Polishing Machines, of which the following is a specification.

This invention relates to shoe-polishing machines; and it has for its primary object the production of a simple automatic Inachine which can be operated by electrical energy when an electric circuit is closed and in w iic-h the electric circuit is broken by the reir-oval of 'ones foot from the foot-rest.

` Other objects are to provide sim le and eflicient means to swing the polishingrushes against the shoe when the person desiring to have the shoe polished places one foot on the foot-rest, to provide sin-ple and eiiicient means for supporting the brushes to permit of their swinging toward and from the footrest while maintaining operative connection with the source of power, and to otherwise improve and simplify machines of this type.

Tothese ends the invention consists of the novel arrangement, construction, and comscribed, and 'fully pointed out in the appended clair i is.

Fie'. 7`is a vertical section taken on line X 1\,`Fig. 8, showing a front elevation of the mechanism for mailling` and breaking the electric circuit. Fig. 8 -is a vertical section on line Y Y, Fig. 7, lookin f tov the right. 9 is a lvertical section ta en on line Z '/i, Fig. 7, looking toward the left.

Fig. 10 is a plan view of the coin-receiver formed on or secured to one end of the contact or balance lever.

f sired. bination of parts, as will `be hereinafter de- Referring to the drawings indetail, correspondin numerals of reference refer to correspon ing parts in the several figures.

The reference-numeral 1 designates the casing in which the mechanism is housed, and at its lower end it has, preferably,-a forward extension' 2 with yan inclined top 3, which isv provided with an opening 4, into which a person desiring his shoes polished will place his'foot. f By arranging the-upper wall of the forward extension on an incline one can conveniently insert his foot into the casing whether in a standing or sitting position. A hand rail or support 5 is secured to the front of the casing, which may be taken hold of to support one when in a standin f position with one foot supported on the ootrest.

Beneath the opening 4 and substantially parallel with the upper inclined wall of the forward extension is an inclined yieldin 4 foot-rest 6, on which the shoe to be polishe `is placed. Two cross-bars 7, suitably supported in a fixed position, have each espiral spring 8 secured thereto, against which ,the foot-rest 6 bears or is secured as may be de- The foot-rest is thereiore yielding to pressure exerted thereon by the person having his shoes olished. f

A toe-brus 9 and a heel-brush 10 are located at o posite ends ofl the foot-rest and are secured) to parallel transversely-disposed

shafts

11 and 12, respectively. The shaft 11, carrying the toe-brush, is journaled in suitable fixed bearings 13, secured to the easing, while the lshaft 12 is journaled in the ends of corresponding arms of two bell-crank levers 1.4, similarly disposed and pivotally secured Patented Nov. 6, 1906. l

to the sides of the casing. The ends of the l other arms of said levers are connected by a bar 16, which passes underneath the foot-l rest and is held thereagainst by a cli 17 or' other equivalent nzeans to compel t e said bell-crank levers to be moved bv the footrest. This movement of the bell-crank levers swings the heel-brush inward against the shoe, and the pressure applied can be regulated by the pressure exerted against the footrest.

18 designates the two inclined side brushes, which are arranged lengthwise of the footrest o n opposite sides thereof and secured to Ico' l thus causing suitable shafts ia The said side brushes are substantial?7 parallel and each 'shaft thereof is ournale 1n corresponding arms of two Abel crank levers 19, suitably pivoted -to the action o the foot-rest when raised by the springs 8 or lowered by pressure applied against lthe upper side thereof.

It is'apparent from the foregoing lthat nor mally the foot-rest is elevated by the springs 8, and the side brushes and heelbrush arev swung outward, owing to the bell-crank levers 14 and 19a being connected to said foot-rest and when the person havin his shoes polished places his foot upon the footrest the said brushes are swunf' inward against the shoe and the amount ofa pressure desired can be easily regulated-'by exerting more or `less pressure onthe foot-rest.

The brushes may be revolved by any suitable source of powerand by any practical transmissionniechanism from the. source of power; but Nieve-devised a simple and novelarrangement which will permit the revolving of the side brushes and heel-brush irrespective of their positions,A `hich can be varied to suit the different size? of shoes being polished. ,It is obvious that 1n order to polish asmall shoe the foot-rest must be lowered farther than when a large shoe is being polished and in all cases the exten-t of inward. movement of the side brushes and heelbrush is always proportionate to the movement of the foot-rest. In the dra-win s I have shown an electric motor 23, to the s aft of which is securedaJ bevel-gear 24. A vertical shaft 25 is journaled in suitable brackets 26, and at its upper end 1t has a bevel-gear 27, which meshes with the bevel-gear 24.011 the motor-shaft'. At its lower end the shaft 25 is provided with two bevel-

gears

27a and 2,8, the latter meshing with a corresponding gear 29, secured to a transverse shaft 30 and the former meshing-'with two bevel-gears 31, secured to flexible shafts 32, coupled to the shafts carrying the side brushes. The transverse shaft 30 is provided with a sprocketwheel 33, around which and a sprocketwheel 34, secured to the transverse shaft '11 a sprocketfchain 35 passes. The transverse shaft 11, which carries the toe-brush, is provided with a second sprocket-wheel 36, and secured to the shaft 12, carrying the heelbrush, is a sprocket-Wheel 37, around which and the sprocket-Wheel 36 a sprocket-chain 38 passes. Movement is therefore transmitted from the motor 23 to the vertical shaft 25, with which the shafts carrying the the side brushes to respond to lmea-ns of said flexible essere side brushes are flexibly connected, and by connection said side brushes are revolved irres ective of what their positions may be. rom the vertical shaft movement is imparted to the transverse shaft 30, which transmits movement through the medium of the sprocket-chain 35 to the sli-aft 11, carrying the toe-brush, which in turn transmits movement through the medium of the chain 38 to the shaft carrying the heel-brush. The heel-brush when swung inward will still be revolved, even though the chain 38 be slackened, the weight of the same causing the slackncss to a pear between the two sprockets over which 1t rides.

' A pan 39 is located in the bottom of the V casin and in said pan a supply of water may be he d. When the brushes remove the dirt and dust from the shoes, it will settle and drop into the water and become moistcned. This prevents the dust and light particles of dirt from being carried about in the casing by the air-currents caused by the revolving of the brushes.

'It is of course necessary to provide means for revolving the brushes, but only when the machine is in use, and this is controlled by the deposit of a coin of predetermined denomination. y

46 designates a coin-chute Whichhas its upper end extending out through the casing. Beneath vthe lower end of said coin-chute is a coin-receiver 41, formed on or secured to a balance-lever 42, fulcrumed on a stud 43, projecting from the wall of the casing. The opposite end 44 of the balance-lever acts as a contact, which is adapted to be swung against a fixed contact 45 secured to the casing. Suitable circuit-wires 46 connect the contacts with the motor and supply-wire, and to assure a break or interruption of the current when the coin is removed from the coin-receiver the contact end of the balancelever is weighted, as at 47, When the coin deposited is of light weight, the Weight 47 may be dispensed with and the lever fulcrumed to keep the coin-receiver elevated until a coin is deposited. On depositing the coin in the coin-receiver an electric circuit is established, and the motor and poiish` brushes are consequently revolved and continue to revolve until the coin is removed from the coin-receiver.

48 designates a bell-crank lever secured to the casing in rear of the foot-rest, and it has one arm connected to the foot-rest by a link 49 and its other arm connected to the lower end of a rod 50, which is pivotally connected at its upper end to a ratchet-arm 51, held loosely on a shaft 52 and having a pawl 53 pivoted thereon, which engages a ratchetwheel 54, secured to said shaft. The latter has also secured thereto a gear-wheel 55, and it is journaled in suitable bearings 56, secured to the casing of the machine.

IOO

' 57 designates a shaft suitably. 'ournaled and allranged parallelto and pre erably in advance of the shaft 52, and it as secured thereon a pinion 58, -which meshes with the.

gear-wheel 55, anda cam 59, which is adapted to release the coin from the coin-receiver..

The propertion'of the gear 55 to the pinion 58 is'suchas to.- cause the shaft 57 to make two complete revolutions While the shaft 52 makes one revolution. v 1

The coin-receive is separable and has its walls inclined inwardly and-downwardly to form a hop er-like receptacle, and one side `wall ther'eo .is ivotally attached by a pivotin-60, aroun which a spiral s ri 61 is eld, which tends to keep saiv si e -wall closed. The freeend of the ivoted side wall is'provided with a lip 62, w 'chthe cam 59 is adapted to. engage and cause the said Wall to swing open and release the coin de- .'posited therein, when it drops into asecond coinchut`e 63 and is delivered `to a coin-rece tacle 64.

he operation of the machine is as follows: On depositing a coin in the coin-chute it enters the coin-receiver, tilts the balancelever, and causes.- the contacts to coact, thereby establishing an electric circuit, which causes the motor to revolve. The polishingbrushes are therefore revolved through'the medium of 'the intervening transmission mechanism. 0n exerting pressure on the foot-rest, on which the person having his shloes 'shmed may now place his shoe, or on which he may have placed his shoe previous I to`depositing the coin, the brushes areswu inwiardagainst the shoe with the desire cot-rest `,causes the ressure. The downward movement of the over one tooth on the chet-Wheel 54, whic it then engages. When one shoe is polished, it is with rawn and .the other foot p aced on -the foot-rest. During the time this change is made the springs 8 elevate the footsrest` and cause the pawl 53 to revolve the shaft 52. The -placing of the otherl foot on lthe vfootv rest causesa return movement ofthe said pawl, and when the second shoe is polished and the foot removed the foot-rest 1s again elevated and the pawl causes the shaft to revolve another. portion of a revolution. The proportion of the parts is such that the shaft 52 is caused to revolve one-fourth of a revolution while two shoesare shinedkan'd the shaft 57 is therefore caused to revolveone-half al revolution'. The releasing-cam 59 is provided with two opposite steps 65, .and

consequently a coin deposited in the coinreceiver is discharged when the lshaft 57 makes one-half revolution, which causes the bell-crank levers arrange contacts to separate, and thus v-break the electric circuit.

Having thus described my invention, what I claim is i 1. In a shoe-polishing machine, the combination of a spring-supported foot-rest, a

fixed transverse vtoe-bru longitudinal side brushesmovable toward and from the footrest, a transverse heel-brush movable toward and from the foot-rest, and means for revolving said brushes. l e
