Application iiled October 31, 1908. Serial No. 460,533.

viLLn, a citizen of the United States, residi ing at Lancaster, in the county of Lancaster v and State of Pennsylvania, have invented l tangular'quadrilateral in 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, s uch as it appertains to make and use the saine.

The main object of this invention is to provide for brushing and polishing boots and shoes on the wearers feet by means of pairs of brushes 'acting on the sides of said shoes and additional brushes for the tops of said shoes,

the foot rests and the chair for each wearer being carried along by mechanism so as to bring the shoes properly into contact with said brushes, the chairs and foot rests being afterward moved around the chair track to their first position. To effect this general object, I provide certain novel devices for thus carrying said chair and foot-rests in guide ways constituting an enduntil their work is done, then movin@ them vout of the way of the shoes for the Ifoot to pass and'temporarily holding them in such position out of use and linally automatically restoring them to their operative position ready for the next pair of shoes.

My invention also consists in divers details and incidental improvements of said machine substantially as hereinafter set forth and claimed. y

In the accompanying drawings Figure l represents a plan View, partly broken away of a machine embodying my invention; Fig. 2 represents a side elevation of the same, also partly broken away; Fig. 3 represents a section of the same on the line 3--3 of Fig. 1;

Fig. I represents a vertical longitudinal section of a part of the same on line M of Fig. l; Fig. 5 represents a plan View of o ne of the top brushes and proximate parts; l"rg. a top brush lifted by the shoe, with other parts:

Fig. 7 represents a detail side elevation of the locking devices for a top brush; Fig. S

represents a detaii section of parts of the io will enable others skilled in the artto. which i gearing and Fig. 9, a side View of the slotted plates for one of the side brushes.

A designates the elevated platform of myv inachine,which is preferably an elongated recform, having steps a at each end for conveniently ascending and descending, and sides A, said steps, sides and platform constituting a hollow casing for the two sprocket wheels B, their shafts C and S and their endless chain D, whereby each chair E is carried along by contact of any lug-Z of a series raised at. intervals on saidchain with a block or lug c extending downward from said chair through a slot f of a guide-rail or track I1` fixed to platform A, said slot and rail being endless ai'id of elliptical form. One side of this elliptical track is directly over the said chain.' The said wheels are faston their shafts, one of these shafts being the main driving shaft of the machine, so as to,v keep up the forward motion of the chain and of all chairs in position to be acted on thereby. For convenience of illustration only one chair is shown in the drawings, but of course there may be several, all traveling along together. Said driving shaft may be actuated by a motor S through suitable gears s or in any other convenient way.

G designates a pair of vadditional rails or tracks for the shoe supports or foot rests Il, which are connected to the chair by arms /i and run on said tracks. Each of these additional rails or tracks has a longitudinal slot g throughout its length and these slots receive small lugs ll on the bottoni of toot rests H, which lugs extend a slight distance down intovtheni, in order that the said rails may guide as well as support said fool rests, l I

though readily permitting their disengagement at will by manually tilting the chair on its rollers E, which run on track F. That part of said track on which the chair is drawn forward by said chain is located between these two additional tracks or rails.

vI designates a pair of upwardlyY tapering brushes which receive a shoe between them and polish the"`saine as the foot rest inoves on as hcreinbelore described. These brushes are carried by shafts J, which are drawn toward each' other b v an intervening spring K sind connected by universal or double joints L to short verl ical shafts M, journaled in bearings m which are fastened on frame N. A shaft O, extending transverselyof the machine and turning in bearin s n on said frame, carries beveled pinions engaging similar pinions m of shafts M, and thus drives a pair of rotating side brushes I. S: 'd' shaft O is driven by the main shaft S thr= ugli suitable intermediate gearing. Ireferably as shown, a longitudinal shaft P s employed for this purpose, connecting with all the shafts O by bevel gear pinions p and p and having as many pinions p as there are shafts O. Bevel gear pinions p2 p2 connect shafts S and P for transmitting rotation to the latter. 'Ihe first pair of side brushes I in the order of travel is generally used for cleaning the shoe, the second for applying blacking, the third for polishing and the fourth for completing the polish. The material of the brushes may vary accordingly.

devices for operating each y pair of side brushes are the same, only those for one pair have been shown in full.

Each side brush shaft J turns in a bearing or bushing z' of a plate I, movable transshaft J of that pair, giving itmore or less.

lateral inclination. f A stud J on iixed plate Q passes up through slot I2, so that the late I is permitted to slide laterally over pate Q with such lateral pivotal movements 0f shaft J and is guided in such sliding by said stud and the walls of slot Q2, the double or universal joint L permitting such movement without bindingwvhile the shafts J and M rotate together as described. The forivard movement of foot and shoe with the foot rest forces the pair of brushes I apart against the pull of spring K-and the latter holds them yieldingly against the shoes at less inclination than before. After the shoe vpasses the two brushes rest evenly against each other from end to end. The tapering shape and inclined position of said brushes are found to best adapt them for fittingI against the inclined and hollowed surfaces ofthe inner sides of the shoe. The slot.Q'- in each fixed plate Q is made broader than the diameter of said shaft., to allow play of such shafts thus jointed, and the stud J permits slightpivotal movement of late I corresponding to such movement o said shaft.

A belt 1' from a pulley O2 turning with shaft O, to pulley R2 on a vertical shaft R drives the latter in its bearings carried by the frame. A pinion R of the latter shaft meshes with a pinion t on the shaft T of the upper or top brush T, which operates B ut these are matters of conf venience and choice, not obligatory. As the onthe top of the shoe a. littlebeyond 'the pair of side brushes- I in 'the direction of travel. This top brush has a concave sur-lv face, to lit better on the rounded surface of the instep. Its shaft T is mounted for rotation in horizontal bearing t of an angular bracket U', which moves as one piece with a sleeve U, surroundin the upper part of shaft It and having slig t vertical play thereon. This play suifices to allow a tooth U2 of said bracket below said bearing to settle into a notch V of a fixed horizontal semi-circular bai` oi' rail V, or to ride up on the said bar out of said notch, as the said sleeve, bracket, shaft and vbrush are lowered or raised vand turned, all together. Said sleeve has a grooved pulley W and a wheel lV mounted on it, so that-it and these two Wheels turn together. A cord W2 is connected to said pulley W and asses around the same and around a gui e pulley W3, mounted horizontally at a fixed point to one of the tracks G last mentioned, its other end being connected to the. rear end of a bar X which slides in guide ways X of said track. An arm X2 of said bar, pivoted thereto, carries a stud y which extends upwardly through a longitudinal guide slot Y of the said track into the path of the footrest travelin thereon. The forward `end of said gui e slot is inclined laterally at Y. A replacing spring Z is connected to wheel W in vsuc manner as to act in o 'osition to the pull ofthe bar X 'on pulley and sleeve U as said bar moves forward, the other end of said sprin being fastened to the frame The ppleration of these devices is as follows. en the shoe having been acted on by the rotating side brushes, reaches the' top brush, thelatter, also rotating, brushes the top of the shoe andthe instep. The Wedge like action of -said instep then raises said brush and its shaft and said bearing, thus freeing toothfU2 from notch V and the forward pressure ofthe travelingV foot rest against study carries said stud along the longitudinal part of guide slot Y with similar motion of arm X2 and bar X and vconsequent pull on cord W2 and pulley W,

turning sleeve U and bracket U', so as to turn shaft T. and top brush T laterallysout of the path of travel of the shoe. As the stud y reaches the laterally inclined end Y of slot Y, the pivotal attachment of arm X permits the rounded corner of said foot rest to force said stud into said inclined end of the slot and said foot-rest holds it there until it passes said stud, the top brush being quite out of the way during this pei'iod.- As soon as the font rest has passed the said stud the" laltter'isrfi'ee. The action of the replacing springnthen first draws it again into the bar and connected parts to their first or nor'- next customer takes his seat in it.

Amail position. At the beginning of this replacing movement the said pivoted arm yieldsas before to permit thereturn of the stud y from the laterally inclined end of the slot into the main longitudinal part thereof. During the above described action of the said side and top brushes on one boot or shoe, theA corresponding brushes are of course acting in the same Way on the other shoe and passing through'the same successionof movements simultaneously to effect the same' end. .This is repeated with eachsuccessive two pairs of side brushes and their top brush. Of course it is possible to dispense with all except the first set of side brushes and top by. hand or otherwise before their action. At the end' of the brushing journey the occupant ofeach chair leaves it, passingv down the steps; an attendant tilts the chair slightly to -remove the lugs H from the slot-s and then moves the chair on its rollers around to the other side of the platform and to the end from which they start. One chair is always near thestarting point. The

The attendant pushes it far enough forward for the block e to be caught by the next lug (l of the chain so that the latter will carry the chair and its footrests forward as described. In the meantime theA next chair has been pushed to thepface at first. occupied by the first chairf'and this is repeated as often as customers appear or until all the chairs are in use. `The return side of the elliptical I track constitutes a source of supply of chairs awaiting occupants.

I The gearing of the machine is calculated to 'rotate the brushes much faster than the sprocket wheel driving the endless chain. I do not conne myself to any particular form of frame or shafts or brushes oi' bearings, thoughthe forms shown are generally preferred.
