`The form and design .of'the outside'cabilnet or casing is immaterialjand' 'may be varied, therefore, j-'none-l is vshown -or described.'

There are-two side 7' brushes, Gxadapted i which is-fiXed a Jfoot pedestal,"P. Each o 4these brushes isv composed; of several sides arranged in polygon form having the bristles on one side of each somewhat longer than those of 'the other sides..- Each of these'8-5 brushes has al compound. motion, viz.,ga long gradual progressive movement `from the toe A to lthe heel of the shoe andl return, and asameplane as the progressive motion. There isone toe brush, H3,polygonal in form and adapted to travell from the toe to the l instepf ofi the shoe, and over and about the -top and sides'thereof. This brush also has scribe a semicircular movement about the heel. This vbrush .has a reciprocating curvilinear motion on a center coinciding with the center 'of the heel of the shoe. In action, ,both thetoe brush and the heel 105 brush Aextend to, cover .and overlap, within parts l65 i their respective zones, .the field covered by the side brushes, so that` -no portion of the shoe is left untouched in the operation. The

reciprocating action of the side brushes is vproduced'as follows :f4-The main drive shaft, A, 'having bearings in the .frame,.Z, andthe extension arm, Z2, respectively, receives the power from a-pulley, A1. Attached thereon by'a 1in in the keyway, a2, isthe traveling screw gear, A2, vforced to revolve with the shaft, A, thereby, but free to slide longitudinally thereon While revolving.4 l Meshed with said gear A2, is a screw gear, A3, fixed upon the .shaft,-B, said shaft lying a't right angles to the shaft, A, and arbored in the- 4 sliding arms A4, and A5. The sliding arm A4, is adapted to travel-along the v'shaft A,

carrying 'with it the lvvorm gear A2, enmeshed with the worm gear A3, and the arm A5, is adapted-.to travel along the sta'-v tionary guide rod a, which is parallel with the shaft A, and extends from the frame Z, to the extension thereof Z2.

.Each end of the shaft Bis provided with a balance crank wheel B1, having a crank pin b, and Voneach is pivoted a pitman b1. Supported in'standards'Z3, on each side of the frame Z, are the guide rods. C, upon which the side brush carriers'Cl, are mounted, so as to slide freely thereon. The pit- "men b1., are pivoted to these side brush car- Iriersre'spectively. It is therefore obvious horizontally .from the franie Z. On `the 4gear D2, in mesh with a fourth bevel gearv lower end of the ,shaft d, is a third" bevel D3 ai'iixed to one end of the horizontal shaft (Z1. The shaft (Z1, has its bearings .centrally in the arm a, extending vertically ,from the fra-me Z, and carries on-its other end a fifthl bevel gear D4'. This' bevel gear' D4,* is per-V manently in mesh with `the two oppositely facing bevelgears, E1 and E2, both of which last mentioned gears a-re-idlers on the screw shaft E. Within the inclosure formed by the three bevel gears D4, E1, and E2, and centered on the screw shaft E', is the reversing clutclrES.v This clutch is centered by means of a fin and a short keywafy in the shaft E, so as to ca'use the shaft E, to revolve with it and yet to be free to slidey longitudinally along said shaft between the 'bevel gears E1 4and E2, with each vof which it is adapted to engage through tlie ratchet teeth, e, with which it and said bevel gears are provided. Clutch E3, is also provided with the annular .slot e1, to' permit of thev introduction of the pins, e2, from the forked end -of the horizontal reversing lever F, which lever is` pivoted to a lug or post el,

- projecting from the frame. Z.

The screw shaft E, is suitably centered in vertical. bearings in standards, P and. Z4, -from the frame Z, and isprovided for the required distance with a screw thread g, adapted to actuate the-nut 'or traveling piece G, which is centered thereon and tapped with the necessary internal threadito engage therewith, Fixed yupon this traveling piece G, and extending upwardly are the aforesaid two arms' A4 and A5, carrying the shaft B, When,l therefore, the shaft E, is revolved by the action of the clutch E3, the

-traveling vpiece G, progresses slowly and carries along with lit the Vwhole construction actuating'the side 4 brushes heretofore described.

The eccentric action of the toe brush H3, is produced as follows :y On'the-shaft B, located about centrally, is diagonally fixed. the cylindrical compound eccentric cam H, adapted to revolve lwith said shaft. `lncasing this cam is the sleeve H2, adapted to be actuv ated by said cam and providedv with the .bifurcated brush extension rod H2, adapted i to rest upon the guide'bar 71 which extends `between the uprights, al, J, On the exv'treniityof this rod'H2, is mounted the toe brush H3. Thus, 'when the shaft B, is caused to revolve, the "cam H, rotating therewithcauses the sleeve H1 to oscill'ate transversely of the apparatus andalso to rock in a `vertical plane. The rod H2., resting upon the bar, ampli'fies `thisniotion at its outer end and causes the toe brush H3, to reciproc'atetransversely with a 'clipping motion as it approaches each extreme. At vthe same time this whole construction actuating the toe brush H3, progresses slowly, being carried-along by the traveling piece G, as hereinbefore described.

The semi-circular movement ofthe heel brush'Kl, is produced as followsvz-On. the

extreme endlof the screw shaft E, is the idler disk I, havingv the crank pin-engaging one end of'the rod or pitman 11. The other end .of this pit'man is freely pivoted to the vertical lever I2, which has' its ful# cruln at itslowerterminal in a lugv z5, and

extending l'upward from the bed plate of the frame Z. 'To this vertical .,leveil2, at a point above'the pivotof the pitman I1,'is freely pivoted the horizontal rod or link-I3,

which connects-said lever 12 with one'end Saidsector 'of the sector gear leven-1*. leveris pivoted'centrally to a standard G1,

from the standard. P, on the bed plate of the frame Z, and has at its opposite end the teeth meshmg with the teeth` of the pinion I3, whlch is freely centered inthe foot rest P, at a this pinion i5, is the heel brush carrier K. Centeredv by afn 'and keyway on .the

screw' shaft E,:immediately adjacent to the disk I, is the Q to tudinally thereon ,While so revolving and edrto the idler dislr'l, which, through thepitinan 11, is converted into a reciprocating inotion in the lever l2. This reciprocating motion is transinittted by thelink I3, to the oscillating sectorlever I4 and Athenceb the c i .Y

meshing teeth 2, to the pinion l5, imparting to' ysaid pinion and the heell brush carrier K,

' engaged by the' slide clutch L, by the vpressure of the spring Z2. 'This engagement 1s a reciprocating semifciroularmotion. 1

As it is desirabie to have the yside brushes shoe 1when operating, it is obvious vthat the 'oscillations of the heel brush must be suspended' at 'that stage, 4hence the disk, Lis

inadeto idle on the yshaft E,'.except when broken and restablishe'dby the following construction: In the clutch L, is the `annular slot-Z3,- adapted to engage'pins inthe biihircatedI lever L2, which is pivoted at its loWe-r' end to' the bed plate Z, and which .connected interinediately by thelinh L3, .to-`

the lower end the lever L4. This lever L4.,is pivoted centrally to an upright from `the bed plate Z5 and has itiipper end pro# vided With a, roller it, located iii-the. path of lthe beveled toe g1', projecting horizontally from ythe travelling piece @,'so as to be torwardly -depressed'around Lits .-ulcrum when said toe makes contact'with said roller' l1, and `to be so lretained until said Contact is renio'i'fed. 4{Bythisaction the' lower Vend -of-'the lever L4, is drawnA backward from the heel construction, pulling Withfit -the link L3, and the Ahii'urcated. clutch rod L2, with its clutch L, and thereby disengaging the -Contact thereoivvith the'. dislrl, and

This raising Aand'loweringis accomplished as follows: `aultably disposed, as on arms, Z1, r2, is a trip,- M*, beveled on its under side as shown. 1n Fig.4 1, so as to engage andwedge down the outer end of member, Mi,A when the i latter is brought beneath it by the recipromade at the llast swift reciprocal stroke of? theframe, C4, under the action of the pitcation .of the. frame C4. This contact is man, b1. The screw shaft, E, carries the traveling piece, G, `to a point where the next member, m2, asdescribed above. Vhile this is occurring, the reversing gears change the direction of rotation: of the shaft, E, and consequentlythe direction of the traveling piece, G, whereby-the frame, C, and member, M3, are withdrawn beyond possibility. of a second contact by M3 with trip M4. As-soon as the former is pulled from @beneath the-latter, the flat spring, m4, re-

stores the toeA of latch, m2, into its normal po/ sition with relation to the ridges, M2, leaving'V inf number, one for each side brush C2, and yare l located at nearly the end lof the long progressive trip of these brushes, at the the brush, C2, free to rotate in a proper direction to present the nextv brush face to-the shoe, and until impeded by' the following ridge,\M2, meeting .the latch toe, m2. This rotation is almost invariably accomplished by the inertia of the mass of the polygonal tum of its rapid reciprocal stroke. As soon as the brush face of C2 contacts' with "the shoe, this settingof `the parts, if not entirely accomplishedby lmomentum, is

completed by this contact so that the face in operation on the shoe-is held in proper p0- sition by the combinedeflects of the pawl,

V*M-l, on the rack, M, and the member m2 on the lug or ridge, M?, so as to be locked there- J ous thatv this releasing operation of the check on the rotation of brush,-C2, must be made atthe last reciprocation and must occur but once. Two or more lsuch operations might result in a turning about of two or -n1ore brush sides., as the throw caused by the rapid rcciprocations has a tendency to rotate The helical spring, m?, is also com-4 pressed for the next operation. It `1s obv1 consist of several component faces is to furrush one or more brushesto clean the shoe,

.then a dip or blacking supply I brush.

to apply the medium after which a series of brushesfto dry and bring up the polish. Inmy drawmgs I-,have shown six faces arranged as a regular hexagon, lbut itis ob- 4vious that 'any practical numberof faces 'may be-employ ed,-as the character of the expeditiously with more or less faces.

vThe dip brush face is composed of longer bristles than those used in the cleaning, drying and polishing, so that the extremities of'this face shall describe a larger circle in itsI intermittent rotation, than the circle described by the other brushes.` The reason for-this isl that it is necessary for thisface to makecontact with the blacking supply, which must, of necessity, be beyond the reach of the other faces, and it is further desirable that this brush should be brought in firmer contact and exert Aa greater pressure on the shoe, than the cleaning and polishing faces, to insure'an elicient application of the blacking to thel shoe. `The blacking supply receptacles are two heel 'end of the machina: They are mounted upon suitable projections from the bed plate Z, 'at a correct angle to present a fiat vertical plane surface of shoe blacking composition in a plane parallel to that of the face of the dip brush. Each'receptacle is com-l posed of a reservoir N, for water or other reducing liquid, and, directly underneatl1 a box N1, for the blacking. f The reservoir has ak small outlet provided with a valve n .the stern nl, of which protrudes into the line of travel of the lug n2, onthe bcxN1. This box, N1, which is provided with a wire gauze front wall n3, to be presented to the bristles of the dip brush, (Fig. 7a) is not lxed to any portion of the structure, but is merely yieldably fitted about or suspended uponv a T shaped plungerN. (provided with the hollow stock, N2) which lits snugly within it and forms its back wall. The blaclring material fills the spacel between this. plunger' and the gauze front. The stem of the plunger N2, is hollow and is fitted over the rod N4, projecting from the `support or. standard, from which it is forwardly urgedby the pressure of an expansion helical spring n4, but held in lilnit'by the pin a5, through opposite slots in the plunger stemt The plunger, N3, is also yieldable and the force of the helical spring, n, is transmitted to the llt box, N1. Thus the entire blocking receptacle eXuding moist blacking, is jolted by the rapid reciprocating strokes of the dip brush, the force vof the impact being directly through the massoi' blacking material and tending to force the material throughlthe gauze. When this brush, `carried along by its connectionsi with the traveling piece G, reaches the bla'cking supply, it jolts, by the action of the pitman b1, the Walla?. and

box, N1, to which the gauze is attached,. the

mass oi-blacking material Within, and the ranging the location of the receptacle nearer or farther from the extreme end of the slow progressive trip. I'f desired, the air space Ivvi'thin the Ireservoir N, maybe'compressed so asf to force out the liquid in jets, When'the so vvalve n, isopened. The two side brushes furnish the entire supply of blacking to the shoe, the toe and heel brushes, spreading it ontop and behind, by reason of th'e over-v lapping of ytheir respective ield's, on 'the I'side brush Zones,v as hereinbefore mentioned.l The successive sides of the toe brush H3, 'are alsopresented to' the shoe at 'periods corresponding. With the changes of they side brush lfaces. This brush is freely fcentered;

go-horizontally, within the bifurcated end of4 the rod H2, andl has fastened concentrically oiione end a radial rack h1, Fig.' 13, engaginga pawl 71.2, mounted on said rod H2,

, which acts to prevent' adverse action, as in e5 the case of the sidebrush construction ,as already described. On. the opposite end of fthe llnushfstock, H3, are arranged radial lugs or'A ridges, h3, (corresponding to lugs,

M2, inthe side brush construction) acted 50, upon by the slidable spring-latch, h4, (cor- "f lresponding 'to latch m2 in the side brush construction), Which is cariied by the spring lever., J2, (corresponding to lever lVP in the side brush construction), which in` turn is ,pivoted at T tov an arm of the bifurcated brush holder, H2, and Which extends rearward so as to be brought under and against` the fixedv trip, h5, (corresponding to M4, in function, of vthe side brush construction) $9 which extends from the bed plate. This trip is adjusted to so interfere with themo-vement of the lever, J2, imparted by its connection with the rod or holder, H2, .to which -it is pivoted, as to swerve 1t on its pivot, "ll, so that lthe tip of the latch, la?. .at

agitates the entire construction of the black. ing` container,V viz: the. gauzeA front, 11.3, theA` the plunger N3, on the rod N, and by ar the opposite end will lclear the lug, h3, with which it has just been engagedand be free .'to spring outwardly under the action ofthe helical spring, H5, and tojpassbey'ond said lug, so as t'o be ready when returned to nor- ,ma l position t'o impede progress of the4 suc'- -ceeding lug. 'lVhen, by the ombined results -I .ofthe rotation of. the cam, andthe return movement ofthe carrierGr, the lever, J 2, is freed from contact With trip, h5,'the pressure spring, J 3 causes it to return to its norreturn tto a place in the line of rotation of the next lug or ridge, h3. As`in the case of the side brushes, this action takes place but once, that is, at the 'last rapid reciprocamal position so that the tip of latch, vfwill tion transversely and While the reversing. I

gears are changing the directionof the movement of, the carriage, G. I,does not aid inpturning the toe brush, as is the' case in the side brush action, this toe.

brush does not att'ainj its proper position until contacting With they to'e of the shoe..

VVhen, howeyer,l this contact occurs, this brushimmediately ,assumes its proper angle withthe shoe, by rotation on its'axis, and

is then held locked between the' latch h4.

pressing the ridge h3, and the pawl, .12,2, pressing the rack, h1, on the opposite end of the brush stock, H3. Y

. VrIhe timing ofthe Amachineis such that the traveling-piece Gr shall. start ,at the toe end of 'the machine and shall make as many complete journeys to the heel end andreturn, as there are faces'on. the side (and toe) brush polygons, viz :in the hexagonal form, vsix complete trips, so as to gi've each re- A-s momentumI spective side acomplete period of activity on the shoe during an entire round trip. It is, of course, essentiall to stop the machine afterthe final trip, aty which time 'the side'- l' and toe brushes must be in the same posi-V tion as they Were when the operation began,

and .thusready fo.` another complete operation. 'This is' accomplished by mounting a cam, O, on a suitable bearing from the frame, Z, the periphery of which cam is in A' the contour of one complete turn of a regu- Ho, is produced. Concentric with 't is cam .and adapted to move with it andcarry it along ,is the ratchet Wheel, O1, having as many teeth as theside brushes have faces. Suitably attached to the traveling piece G is the 'spring paWl Q2, adapted to, engage, onewardly through guidev channelsin the pieces,

1 lar spiral', Where'by the inequalityof radii,

041, of, projecting from the frame, Z.. A t the beginning of thel operation, theroller end of the rod rests within the indentation 0. It

' is therefore evident that, as the ratchet O1 machine.

At the upper end of the rod O4 is' attached any of the conventional electric contact breakers, so that the drop of the said rodwill open the circuit and stop the As I do notfinclude any special form of v coin'controlled mechanism for connecting construction.

the motive power, I do not Vdescribe such The foot' rest'is placed'directly forward of the heel brushA construction, and in the path of the vtoe brush and between the line of travel of the two side-brushes. A yield4 5 ing and self-adjusting pressure to the shoe is imparted to each side brushby means of the pressure-spring Cf", one 'end of which is fastened to the side bnush carrier C?, and the other end presses against the `bifurcatedl frame C4, whereby the brush, C2, is urged ,toward the shoe. Y Freedom from lateral motion in `this respect is provided for by having the 'bifurcated frame C, adaptably adjusted to slide within the channeled guide piece, C, on the carrier, C1.

' A spring bar, H, mounted on uprights, J, and acted uponby the -helical springs, J1, supplies the pressurevnecessary to vkeep the toe brush in proper contact with the :front part of the shoe. If desired, thelast brush vface of the side and toe brushes may be provided w'ith a cushion, or other fabric suchas A canvas-ortough muslin, which may be substi'tuted for bristles to complete the polish.

By reason of the rapid reciprocations of the side and toe brushes, combined with the gradual progressive motion back'and forth along'theshoe, it Ais desirable, if not absoi '1utelyessenti'al, to provide a means for the instant stopping of all motion, should the footiof the.user,'for any reason, assume an improperp'osition on the Apedestal ror footrest,
