T 0 all 117/2077? it may concern:

Be it known that I, CHARLES F. Bonn imu'r, a citizen of the United States, residing at New York, in' the county of New York and State of New York, have invented certain new and useful Improvements in Shoe- Polishing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a machine for polishing shoes and it has the object to provide a simple, ellicient and durable machine be polished by a combined rubbing and whipping action of the band, cloth'or wiper relatively to the shoe in imitation of this action as now connnonly' practiced wh en polishing shoes by hand.

shoe for polishing the same. In addition to wrapping the rubbing band around the toe part of the shoe an oscillating motion is imparted to the same in a. direction rrosmvise of the shoe so as to bring all of raid parts of the shoe under the action of the rubbing hand and the latter is also moved bodily in a vertical direction toward and from this shoe in imitation of the action Which is practiced by bootblaclzs, this having the eliert of rendering the polish more brilliant. The preferred means for thus operating the rubbing band comprises a support which consists of a major or main part l havinglhc l'OllH of a vertically swinging arm which is pivoted at its rear end on a fixed horizontal axis arranged transversely to the shoe supporting stand, and a minor or auxiliary seotic-n 5 having rn'eiterably' the form of an :ll'lll which supports the polishing band and is pivotally connected with the front end of .the main supporting arm so as to turn about a rmrnially horizontal. axis which is arrangcd at right angles to the axis of the main arm. In the preferred construction of pivotal support, for the main arm the same is hung at its rear end on a horizontal. driving shaft (3 which is joiirnalcd in 'a' trans verse barring 7 mounted on the adjacent part 8 of the stationary frame of the machine so that this arm can swing vertically about this shaft. The auxiliary arm is preterably L-shaped and provided with a horizontal upper front portion and a depending rear portion which latter is pivotally connected with the front end of the main arm by means of a rock shaft S) journaled lengthwise in bearings 10 on the front end of the main arm and connected with the lower end of the vertical portion. of the auxiliary arm. A rising and falling motion is imparted to the su porting arms for producing the whipping ell'ect of the rubbing cloth on the shoe, which u'ioveinent is preferably, though not necessarily, produced by means of a crank shaft ll arranged and a. link 12 connecting the crank 13 of thecrank shaft with the main arm, as shown. inl ig. 1. I Any suitable means may be employed for rotating the crank shaft 11, those shown in the drawings,

being suitable and comprisan electric motor 1 and a belt 15 passing small pulley 16 on the motor in g around .a

at its front end shaft and a large pulley 17 on the crank This electric motor is included in an.

shaft.

- electric circuit containing a generator 18 or Y so that the same 'shoe while in other sourc-g of electric energy and a switch .19 arranged on the upper part of the frame, preferably-above the shoe supporting stand, is in conyenicnt reach of the person whose shoes are being shined and thus enable this person to start and stop the motor at will.

Variousmeans may be provided for yieldingly connecting the rubbing or polish ng band or cloth. with the auxiliary arm' of the support so that this band while in engagement with the shoe and oscillating transversely relatively thereto will be able to con form to the shape of the shoe and thus permit all parts of the same to be reached and thoroughly polished. vThe preferred means for thus yieldingly connecting the polishing band with the auxiliary arm'of the support comprises two ClOVIlWflICll) bowed springs 20 21 preferably of the leaf type which are secured respectively to the front and rear ends of the upper horizontal part of ihe auxiliary arm, and two longitudinal stretching bars 22 arranged on opposite sides of the auxiliar 7 arm and each connected with one of the corresponding pairs of ends of the springs and also with the adjacent end. of the rubbing or polishing band. Although various means may be employed for connecting the polishing band with the stretching bars this is preferably effected by providing each of these bars on its outerside with a longitudinal undercut channel or groove 38 which opens downwardly and providing the polishing cloth with thickened longitudinal edges or ribs 39 each of which is arranged in the enlarged part of one of the undercut channels while the adjacent narrow part of the cloth is arranged in the narrow or contracted throat of thc channel, as best shown in Figs. 7 and 8. This thickening of the cloth is preferably produced by folding the edge of the cloth around a cord 40 and curing the same together by stitching orotherwise. This construction permits of readily attaching a cloth to the springs and removing the same therefrom when the cloths become worn and require renewal. The front ends of the stretching bars and the channels thereon are bent or turned downwardly, as shown in Figs. 1 and 3, for the purpose of causing the rubbing cloth to conform substantially to the top and sides as well as to the front end or toe part of the contact with the same and promote the polishing action of the same. In the modification of the fastening for the polishing cloth shown in Fig. 8 the corresponding ends of the springs 20, 21 are connected by bars 37 each of which is rovided with a longitudinal row of perfiira tions 23, and the respective end of the polishing band is'secured tothis bar by means of stitches passing through the band and the openings of the companion bar 37.

As the rubbing band is brought down upon the shoe the central part thereof is deflected upwardly relatively to the lateral or longitudinal edges thereof so that the band is wrapped more or less around the shoe and the rear part of the band is also bent or wrapped downwardly over the front end of the toe of the shoe, as shown in Figs. 1, +l and 5, this being permissible owing to the yielding support forthe rubbing band which is furnished by the springs. The latter at this time are drawn together with their ends and strained so as to maintain the rubbing band constantly under tension while in this position. Inasmuch as the rear part of the rubbing band must be capable of wrapping around the front end 'of the toe in addition to conforming to the upper surface of the toe while the front part of thisband need only be wrapped crosswise over the top of the shoe adjacent to the instep of the same, it is desirable to render the rear spring more elastic than thefront spring so as to permit the rubbing band to conform itself readily to these parts of the shoe. The preferred means-for accomplishing this purpose consists in constructing the front bow spring 20 of a larger number of leave." than the rear spring 21, as shown in Figs. a and 5, thereby rendering the front spring stiffer than the rear spring and causing the front part of the polishing band to be held more taut than the rear part thereof, whereby this band is enabled to adapt itself readily to the chang ing formation of the exterior of the shoe as it sweeps in a curved path back and forth around the same. The two sets of leaves of the front and rear springs are preferably.

held in place by engaging the upper or main leaf of each springwith the underside-of the horizontal portion of the auxiliary supporting arm and holding the same in this position by means of a. longitudinal clamping bar 24L engaging with the underside of the inner leaves of these springs and connecting this clamping bar with the auxiliary supporting arm. by means of clamping bolts 25, as shown in the drawings, or by any other suitable means.

The rocking movement of theshaft 9 for causing the polishing; cloth to sweep back and forth crosswise of the shoe may be produced by various means but preferably by end of the intermediate shaft with the gear rack, and a pair of inter-meshing bevel gear wheels 33 secured respectively to the driving shaft and the rear end of the intermediate shaft. The driving shaft is preferably operated from the same motor which raises and lowers the polishing mechanism, the means for this purpose shown in the drawings consisting of a-belt 34: passing around pulleys 35, 36 mounted respectively on the motor shaft and the driving shaft. By this means a continuous rotary movement is imparted from the driving shaft to the intermediate shaft, a reciprocating movement is transmitted to the gear rack by the crank 32 and link 31, and an oscillating movement is imparted to the rock shaft and the polish ing cloth connectedtherewith by means of the pinion engaging with the gear rack. This oscillation of the polishing cloth (301ltinues uninterruptedly during the rising and falling movement of the same inasmuch as the driving connection between the intermediate shaft and the motor is not disturbed during such movement.

During the operation of this machinethe patron places his shoe upon the the polishing cloth is in an elevated position after which the switch is closed so as to start the motor. Thereafter the polishing cloth will be moved slowly toward and from the shoe on the .stand with a whipping action and at the same time this cloth will be oscillated in a direction crosswise of the shoe,- as shown by dotted lines in Fig. 3, so that while the cloth is depressed into engagement with the shoe the latter will receive a plurality of polishing strokes. This is repeated during each subsequent depression of the polishing cloth upon thr shoe andrcsults in quickly producing a high polish on thr shoe. It will be noted that when the support of the polishing cloth is in its lowest posiiion the same brushes or rul the shoe with the heaviest pressure, which pressure is grzu'lually reduced and causes the cloth to bear very lightly on the shoe as the same is being lifted therefrom, thereby rubbing the polishing material vigorously into the shoe during the initial part of the polishing operation and then gradually relieving the pressure so as to leave the surface of the shoe brilliant. After the shoe has been polished the motor may be again stopped by opening the switch. If desired, however, the motor may run continuously, in which case the patron will place hisshoe upon the stand during the upstroke of the polishing band and also withdraw the same from-tho polishing position while the polishing band is in its elevated position.

This construction of shoe polishing machine is i'aomparativcly simple, the same is not liable to get out of order by ordinary usage, there is no liability of injuring the stand while foot while using the same and it operates to produce a very satisfactory and high polish on the shoe in a comparatively short time, thereby enabling a large number of customers to be handled expeditiously and profitably.
