Application filed February 16, 1914. Serial No. 818,995.

ence marked thereon.

This invention relates to machines for blacking and polishing shoes. The machine is of that type designed to perform the several functions while the shoe is held on a suitable rest, and if desired while on the foot of the wearer. The invention is an improvement upon the shoe blacking machine set forth in mv prior Patent No.A 900,448, dated October' 6, 1908.

Objects of the invention are to simplify the mechanism and so construct and arrange the saine as to increase its durability and adaptability for the functions to be performed, and at the same time bring the cost of manufacture within reasonable limits; to provide a machine with which the blacking may be eifectively distributed to the brushes and applied to the shoe at a number of different points yaround the same, thus insuring a uniform distribution of the .blacking over the surface of the shoe; to provide a machine in which the rotation of the brushes for blaeking and polishing the shoe may be increased without increasing the rate of travel of said brushes around the shoe; and to insure a uniform pressure of the brushes against all parts of the shoe without the employment of guiding means for the brushes, other than the shoe itself. Other objects of the invention will appear from they following specification and claims.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described and pointed out rparticularly in the appended claims.

Referring to the accompanying `drawings,- Figure 1 is a top plan view of a machine embodying the present improvements, but omitting the casing, motor, toe biusli,black ing receptacle and distributer and certain parts which would complicate the illustration, but which are embodied in other views.

Like letters of reference in the several iigures indicate the same parts.

rlhe machine of the present invention is designed to be mounted in a suitable cabinet, not shown, in such position that a shoe, preferably, but not necessarily, on the wearers foot, may be placed on a suitable foot-restand through the manipulation of control mechanism which may be governed by a lever, push button or a coin or token device, inaugurate the operation of the machine to clean, black and polish the shoe placed on the foot rest. The general arrangement of machines of this type, in sov .far as the features referred to are concerned is wellunderstood in the art. land hence in illustrating the present improvements it has been deemed unnecessary to'show either the cabinet or the initial control devices, the illustration being therefore limited to the actual operating parts of the machine proper. By reference to Figs. 1, 2 and 3', it

will be seen that' the mechanism is mounted upon a suitable base or bottom plateat the rear portion of which there is a motor sup port consisting of rightA and left hand frames 2 and 3 forming at their upper ends a platform 'upon which an electric motor of any suitable character may be 'placed Vin proper position for driving a main shaft 37 journaled in suitable bearings 4 on the forward side of the frames 2 and 3. The connection between the motor and shaft 37 con- 5 veniently embodies a belt and a driving pulley 72 on the end of the shaft. The shaft 37 yis adapted through a worm and wqrm wheel l to drive a countershaft 94 arranged below and at substantially right angles to the shaft 37, where it is supported in suitable bearings or shaft supports 24 and 26. This shaft 94 is in effect the main shaft. of the machine, inasmuch as all of the driving connections are taken from it, but through differentand independent sets of gearing. One

set of gearing operates to rotate the blacking and polishing brushes on their individual axes, another set of gearing operates to move the blacking and polishing brushes bodily around the shoe being operated on at a relatively slow speed, and another set of gearing operates to rotate the toe polishying brush first in one direction and then in the other. All'of the movements are carried on simultaneously and provision is made for automatically arresting the movement of the parts when the polishing operation is completed, or, if the brushes become jammed or' their movementsarrested by a, misplaced shoe or other accidental cause.

The foot rest, which is indicated in outline only at A in the accompanying drawrings, is mounted on the upper end of a central upright 4l, preferably a tubular upright which is anchored in a central'base piece or support 40, the said base or support and upright serving 'also as the supporting journal about which the several mechanisms, including the brush supporting spi- 40 der and gearing for rotating said spider and brushes and for rotating the brushes themselves, are adapted to rotate. The

brush support proper, which is preferably in the form of a three-armed spider 51, is

keyed on the upper end of a sleeve 42 journaled on the central support before referred to, preferably through the medium of suitable ball bear/ings of ordinary construction.

They lower end of the sleeve 42 is flanged outwardly toform a support for the attachment of a plurality of gear wheels 45 and 46 and fortheattachmentof a toe brush cam 44 to be presently described. The gear wheel 46 is a worm gear with which a worm 69 on a secondary shaft 77 is adapted to mesh, said secondary shaft being driven from the shaft 94 through a train of - spur gear wheels 70, 73 `and 75, whereby thesleeve and brush supporting4 spider' 5l willg be given a comparatively slow rotation around the central support belowfthefoot rest.

- In addition to the spur gear '70 the shaft 94 is provided with a bevelpi'nion 48 'adapted to mesh with acorresponding gear wheel 4T mounted on a secondary'bearing sleeve the bearing sleeve 42 before referred to and adapted to carry a relatively large gear wheel 49.

J'ou'rnaled in each of the arms of the spider 70 5l is a short vertical shaft 54, upon the lower end of which is mounted a spur gear 50 meshing with the large spur gear 49. Upon the upper end of each shaft 54 there is mounted a pulley 55 adapted for a driving 75 belt leading off to a corresponding pulley on the rotary brush shaft. The rotary brushes 74 are each mounted on vertical shafts journaled in the ends of brush carrying arms 53 and 53, said arms being journaled around 80 the bearings in the ends of the brush carrying spider arms 51, whereby they may swing toward and from the foot rest, light springs 53h (Fig. 7) being provided to hold them pressed inwardly with a very light pressure which does not vary materially as they move outwardly.

The brushes being free to swing on their arms independently of the brush carrying spider, the springs 53b urge them lightly into 90 contact with the surface of the shoe throughout the entire movement of the spider in carrying the brushes around the shoe. In this construction the shoe itself on the foot rest A acts as a cam for guiding the brushes in their movement, a most important result, for the brushes are made to contact with every kind of shoe, regardless of shape or size, and consequently the machine operates with equaleiliciency under all conditions.

In the operation of the machine the brush carrying spider is rotated in a direction which will cause its brush carrying arms to trail behind their points of attachment, and thus the brushes are drawn around the shoe placed on the foot rest instead of being pushed around the same, as has been the common practice in machines of the prior art. By drawing the brushes around the shoe there is less danger of a jam occurring such as might alarm the user or even injure his foot, and the action secured is correspondingly softer, lighter and more effective, for it is found with the arrangement shown the shoe may form the sole guide for the brushes, yet they will bear on the shoe with practically a uniform pressure and with no liability to jump in passing around the heel and toe. From an inspection of Fig. 2 it will be seen that one of the brushes 74 is 120 mounted in a plane somewhat higher than the other two brushes, being thus adapted to clean and polish the upper portion of the shoe, or the portion above the sole, while the other two brushes operate more particularly 1.25 on the lower portion of the shoe and edges of the sole. One of the lower brushes con-- veniently forms the blacking applying brush or dauber, and in the present machine it is designed that the dauber `shall have blacking supplied thereto at periodic intervals, and when in different positions around the foot rest, so as to secure a more even distribution of the blacking. With this ob- 'ect in view, the arm 53a on which the dauber rush is journaled is provided with a blacking receptacle or cylinder 89 from the forf ward endvof which a discharge duct 90 leads up into proximity to the surface of the brush. This discharge duct 90 is adapted for the reception of a polish distributer tube 82 which distributer tube is a cap-like strucl ture having a series of perforations 82a therein and a series of peripheral teeth 82".

The teeth 82b serve to separate the bristles of the brush 74 and thereby assist in thoroughly impregnating the brush with the polish. Itis loosely mounted on the d1scharge duct and is adapted 'to be rotated by contact with the periphery of the brush, with the result that polish dischargedV from the upper end of the duct' will be caused to work downthe interior of the distributing tube and will be ground and forced out through theperforations therein by the action of the tube in traveling between the duct and surface of the brush.

In order `to feed the polish or blacking from the containing cylinder 89, the cylinder is provided With a pistony or plunger having a screw threaded stem 892L working through a threaded opening in the head 89b and sur rounded by a sleeve 84 having thereon a star or toothed Wheel 85. The outer end of the 'sleeve 84 is journaled ina bearing91 pivotally mounted on the inner end of the brush carrying arm 53a and the star or toothed wheel 85 is in position to coperate with an operating pawl 83 mounted on the upper end of a stem 83a.L extending vertically through the shaft carrying the gear Wheel 50 and pulley 55, all as shown clearly in Figs. 4, 5, 10 and 11. The operating finger or pawl 83 while free to move vertically into and out of position to coperate with star wheel 85, is caused to rotate in unison vwith the pulley through the medium of pins 83h, and the raising and lowering of said pawl or operating finger is controlled automatically through connections to be presently described. The sleeve 84 is provided with an internal square shaft 84b on which the threaded stem 89a slides whereby rotary motion of the sleeve 84 is transmitted tothe stem and the latter is free to move longitudinally.

vA bell crank lever 86 is pivotally mounted in the end of the brush carrying spider arm on `which the dauber brush is mounted, one

Aend of said lever extending under the vertical shaft 83a on which the operating pawl or finger is carried, While the other end of central support and having in their periph` eriesnotches 59a into which the end of the pawl or lever may drop under the influence of a coil spring 81a, but which may be debarred from entering said notches byf'displacing the cams with relation to each other, so as to close the notches. One of the cams, that numbered 59, is a other, numbered 58, is adjustable so as to open or close the notches, and it is preferably actuated automatically so as to open the notches during -a-portion of each operation 0f the machine, as for example, when black-v ing is to be supplied to the dauber and to close the same automatically when the blacking has been supplied, the design of the machine being to supply blacking during one or more revolutions of the brush aroundv connected with thegcamy through the mediumv of a transverse lpin 87 extending out through slots 87'i in the central'support and at its,l

fixed cam, while the lowerend provided Withan-operating arm or secondary lever 76, extending out through an opening in the basev support 40 and connected with one end vof a lever 60 through the medium of a link 93, (see Figs. 1 and 3). The lever 60 is periodically'oscillated during each operation of the' machine by co7 operation with a cam 63 to be presently referred to.

The container 89 has been referred to as struction the Whole `container may be swung upthrough a suitable opening in thecasing to facilitate relling. v The spur gear `45 is adapte'dto mesh with a timing gear 65 mounted on a vertical axis f at one side of the central support 40 and provided with aV sleeve hub-having at its lower end a pinion 66 meshing with a -large gear wheel` 62, `the whole train of gear,

Wheels 62, 65 and 66 constituting a timing train adapted to control the period during Which the machine shall run for f one opera-v tion. The control mechanismenibodies va'- timing cam vo4 mounted `on the gear wheel 62 and adapted to rotate in unisontherewith. The timing' cam 64 is located above the polish control 'ca-m 63, before referred to, and the starting and stopping mechanism is adapted to cooperate with the timing cam.

This mechanism is show-n in" Fig. y3 and in detail in F ig. 6, fromV which it will be seen that a switchlever 7 pivot-ally mounted on the base isadapted to cooperate with switch contacts 7l, utilized for controlling the current supplied to the elec-tricnaotor,l whereby the mechanism Vis operated. Thel switch lever is moved by spring 7a into position for closing the. circuit, andis `adapted to be moved on its pivotto'fopen said circuit by means of a catch or cut-out `finger 67 pivotally mounted on the -end of a time lever 61,.

The time lever, by reason of the tension ofv its spring 61a, norinallypresses .against the periphery of the time cam y64. When the depression insaid cam permits,the lever is drawn downwardly `in Fig. 6, the hook `or catch end 6.7 on the cut-out finger engages a projection 67h on the switchlever and moves said lever to its open ,position against the tension of its springfa. y For holding the switch lever in its open or circuit breaking position it is j )rovided with an arm 7" having a lnotch or shoulder7c thereon for cooperation with Aa head 22a-on a starting lever 22 to hold it in its operated position. When the parts -arein .the position shown in full lines in Fig. 6, the switch contacts are closed andthe machine is in operation. Assuming that 4'the cam is rotatedto a point where the time lever may move downward-ly, such movement will swing 'the switch lever to open the circuit through the connections aforesaid and will simultaneously release the shoulder 7C from its `engagement with the starting lever 22, and the latter, under the influence of its spring 22h, will swing back to the position shown in dotted lines, thereby holding the switch lever in its open position. Simultaneously with the movementof the starting lever 22 to the position shown in dotted lines, the catch 'orcut-o-ut finger 6T will be released from its engagement with the projection 67" on the switch lever through the engagement therewith of the, arml 22c ofthe starting lever, leaving the :parts in position to have the circuit again established by the simple return of the starting lever to the position shown in full lines. In thelatterposition, however, with the time lever depressed, the cut-out finger is out of engagement with the projection 67", and in order that it may be positively moved back into engaging position when the time lever is elevated, the arm 22c of the starting glever is provided with a projection 22d, with which an incline 67C on the cut-out linger isv adapted. to coperate, so, as to move 'the hooked projection 67a backto the positionk indicated in full lines. The starting lever 22 is provided with a pull rod 92 which extends off to any suitable mechanism, or to a hand lever by which the operation of the machine may be inaugurated.

For polishing the upper surface of the toe of the shoe a vertically movable rotary toe brush 2G*I is mounted on a toe brush spindle 2O journaled to rotate and move longitudinally in a bearing 20h carried by `a forwardly projecting extension of the motor supporting frame. Conveniently, the toe brush spindle 20 is mounted to slide vertically' in a sleeve journal 21 directly journaled in the bearing 20h, the spindle and sleeve journal being connected to rotate in unison. For rotating them, the sleeve ournal is provided with a belt pulley S around which :a belt 8a passes from a belt pulley -9 on the drive shaft 94. Said belt 8f* in passing between the said pulleys is deflected around idler sheaves or pulleys 13 mounted in clevises 12 having spindles 10 j-ournaled in suitable diagonal bearings in the motor supporting frame. The brush is made vertically movable in order that it may be lifted when the :machine is stopped, so as to facilitate the placing of a shoe in position for polishing and also to permit of the passage of the high side polishing brush. In order to 'accomplish the lifting action for the two purposes mentioned, an automatic lifting mechanism is provided, timed to lift the brush at the moment when the high side polishing brush is passed under the same, and a second lifting mechanism is provided for lifting the brush when the nia.- chine is brought to rest after a complete operation.

The upper end of the toe brush spindle 2() is provided with a groovedcollar 18 with which the forked end of a toe brush lever 6 is adapted to cooperate. This toe brush lever is pivoted intermediate its ends at 14 on a bearing carried by the `motor frame and its rear end is connectedby a long link 96 with one arm of a bell crank lever or crank arm 68 pivotally mounted near the bottom of the motor supporting frame and having its other arm connected by a long link 95 with a toe brush cam lever 23. The cam lever 23 is pivotally mounted at oneend on the base plate with its opposite end projecting in proximity to the staring lever 22 and in position for coperation with a toe brush cam 44 mounted on the sleeve 42, preferably beneath the work and spur gears 46 and 45, hereinbefore referred to. The form of the toe brush cam 44 is such that during its rotation the toe brush lever 23 will be moved ina direction to effect a pivotal movement of the lever 6', to ythereby raise the toe brush, and the timing is such that the toe brush will be raised intermittently and at the proper time to permit of Ithe passage of the high side polishing brush beneath the same. The ends of the bristles of the toe brush preferably ordinarily travel in light contact with the upper portions of the low side rpolishing brushes and dauber, and from the latter take a certain proportion of the polish which is distributed thereto by the polish distributer, although it is obvious that, if so desired, the upper end of the `polish distributer may be provided with an opening at 82f through which polish will feed directly to the toe brush.

As before stated, it is desirable that the toe brush shall be in elevated position when the machineis brought to rest after a complete operation, and this result is effected through an operating connection between the toe brush cam lever 23 and the starting lever 22. The connection is kconveniently in the form of a lug .23a on the starting Y lever adapted to engage the inner sidel of thetoe brush cam lever, the arrangement-being such that the toe brush cam lever is free to follow the confgurationof the toe brush cam,

but when the'starting lever 22 is retracted by `its s ring 22 for stoppingjthe machine,

as be ore described, the lug 23L will draw the toe brush cam lever away from' the cam-and v elevate the toe brush `to its greatest height. l :In the practical voperation ofthe machine it isfound highly desirable to reverse' the direction of rotation of thetoe brush during each operation so that all parts Vof the shoe surface will beequally polished, especially where a soft brush is employed. This reversal of rotation is effected by mounting the pulley 9 loosely on the shaft 94 and providing means whereby it may be rotated either by-being clutched to the shaft orto a reverse gear, an automatic shifting mechanism being provided whereby the brush will b e rotatecl'yin each direction during approximately one half of reachfull operation. By reference to Figs. 1, 2, 3 and 9 it-wlll be seen that the pulley 9 is provided with oppositely disposed clutch faces 9 adapted to engage with clutch faces 9" and 9, one

' rfast onl the shaftA 94 and the `other loose thereon# A reverse drive is provided for v,the `loose clutch face 9c,which maybe, for example, the 'spur gears 9S and 9e, the latter being fast on lthe shaft 77 although any `-ordinary or preferred form of reverse gearing may be employed. rDhe pulley 9 has a grooved hubV for co eration with the forked rshifting lever 146 see Figs. land 3)`the outer end of which projects through the side frame and is bifurcated to form a fish tail 1468. An operating arm or crank 145 (Fig. t

,3) on the upper end of an oscillatory sha 145 serves to swing the shifting lever and move the pulley 9 into engagement with either clutch/9b or 9c as the case may be, and to lock4 it in such engagement through the well known locki'n action of a fish tail shifting device. haft 145 is connected through a crank arm and link connection 144 l other and through the connections described shifts the pulley 9 to drive the toe brush in one direction or the other. The cam 141 moves in unison with the control caml and reverses the toe brush at the proper time to cause it to rotate approximately half the period in each direction.

The toe brush should operate with a soft action on the shoe and to provide for this it is yieldingly supported on its shaft 20, the preferred form of supporting connection being shown in Fig. 12.l Referring to this figure it will be seen that the brush 2()a is held in horizontal position or at right angles to its shaft by a spring K surrounding the shaft and pressing against a center. plate L on the brush. The plate L forms a part of or is attached to an annulus vM loosely surrounding the shaft'and connected through a gimbal joint N with the lower endvof the shaft whereby perfect flexibility is provided for the brushV to tilt or ride over the shoe and at the same time it is forced to rotate with the shaft.

In operation, the foot is placed lon the rest between the side polishing brushes and dauber and the machine is started in operation by a pull on thelstarting'rod 92. By pulling on the starting rod 92 the starting lever 22 is swung to the position shown lin full lines in Fig. 6, and as shown in Figs. 1 and 3. This movement permits the vswitch lever 7 to advance under the influence of its spring 7aL so as to close the circuit to the motor, shown diagrammaticallyl at in Fig. 6, and with the parts in this position the motor becomes effective to rotate the driving shafts 37 and 94, and through the shaft 94 to operate the several brushes.

Through the independent'trains of gearing tained and made possible by the arrange- -ment of driving gearing, and' it will be noted that the large gear wheel 49 revolves at a much higher speedfthan the brush carrying spider, and the spider and gear travel in opposite directions.

The trains of gearing employed may be proportioned to rotate the brush `around the foot rest or shoe at practically any desired speed and also to rotate the brushes on their own spindles at any speed found necessary to accomplish the desired ends in the most perfect manner. In other words, the two movements are practically independent of each other, and in this respect the machine differs from the prior machines wherein the Speed of the brushes on their own spindles could not be changed without correspondingly changing the rate at which the brushes are rotated around the shoe. As the machine continues its operation the time cam 64 rotates until it releases the timing lever 6l and the latter, under the iniuence of s rino 61aL and throu h the connectiony formed by the latch 67 moves the switch lever 7, so as to break the motor circuit, the parts then assuming the position shown in dotted lines in Fig. 6,

In connection with the machine, various safety connections are provided for preventing injury should the foot of the person whose shoe is being polished be misplaced in such wise as to block the rotation of the brushes, or if, for any reason the machine becomes jammed so as to stop the movement of the operative parts. Such safety devices embody, for example, the worm sleeve 1, which is held up to its. work on the shaft by the coil spring 1l and in such position is coupled to the shaft by the driving ratchet 86. A very similar arrangement is illustrated in my prior patent before referred to, although the present construction of the device is more efficient in that the driving ratchet will become effective at pratically any angular position with relation to the shaft. One end of the worm sleeve is provided with a groove for the upper forked end of a lever 150 pivoted on the side frame and at its lower end engaging a horizontal lever 151 pivoted on the base and having a projection 151a adapted to cooperate with the switch lever 7. Should the machine jam, a longitudinal movement of the worm sleeve will swing the lever 151 and draw the switch lever 7 away from the contacts thereby interrupting the motor circuit to instantly arrest the machine and prevent any possible injury or alarm to the user who has his foot and lshoe on the rest.

Having thus described my invention, what IY claim as new and desire to secure by Letters Patent of the United States, is:
