,'pecication of Letters Patent.

Application led August 24, 1912. Serial No. 716,835.

To all whom it may concern.'

Be it known that I, CHARLES PEASE, a citizen of the United States, residing at Salem, in the county of Essex'and Commonwealth of Massachusetts, have invented certain Imrovements in Shoe-Finishing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several gures.

This invention relates to shoe finishing machines and is herein disclosed as embodied in a machine for burnishing the edges of the heels of boots or shoes. Machines of this character usually comprise a rotary tool having a working face adapted to give the heel edge the desired finish, and a rest positioned for engagement with the tread face of the heel during the nishing operation to aid the operator in properly presenting the heel to the tool.

It is usual in nishing heels on machines of the character above designated to keep the working surface of the tool covered with a coating of melted wax or other liquid finishing material. If this material is supplied too abundantly, or if the speed of rotation is excessive, the wax will be thrown from the surface of the tool, to the great annoyance and inconvenience of the workman.

It is an object of this invention to provide a guard for catching any wax that may be thrown off the tool in this manner.

Referring to the accompanying drawings which illustrate one embodiment of the invention, Figure 1 is a perspective view of the head of a heel finishing machine, and Fig. 2 is a plan view of a portion of the machine head, certain parts being shown in section. Y

The machine illustrated in the drawings is provided with a rotary burnishing tool 1 of a type commonly employed in machines of this character. This tool is mounted upon the forward end of a shaft 2 journaled in bearings 3 on themachine frame. In order to assist the operative in properly presenting the work to the burnishing tool 1 the machine is provided with a rest 5 arranged to engage the tread face of the work, herein shown as a heel. A split collar 7 which encircles a reduced portion ofy a hollow cylindrical extension 8 of one of the shaft bearings 3 and is secured in adjusted position by a binding screw 9, is provided with a lateral extension 10 consisting of a dat plate arranged to support a carrier 11 for the tread rest 5. The carrier 11 is mounted for free movement in a single plane on the extension 10 to permit the tread rest 5 to be adjusted longitudinally of the axis of rotation of the burnishing tool and radially toward and from' said axis of rotation. To this end the carrier 11 is provided with a longitudinalslot 12 through which looselyextends the screw threaded shank of a clamping device 13, said shank being threaded into the extension 10. With this construction the carrier 11 may be moved in a direction to cause the shank of the clamp 13 to traverse the slot 12 to adjust the tread rest 5 longitudinally of the axis of rotation of the burnishing tool 1, and the carrier 11 may also be swung about the shank as a pivot to adjust the rest 5 radially toward and from the burnishingtool.

In orderto.y clamp the carrier 11 in the desired adjusted position the clamp 13 loosely carries a washer 111 arranged to engage the upper face of the carrier 11. Interposed between the washer 1411 and a shoulder 15 formed on the shank of the clamp is a split spring ring 16. The clamp is also providedl with a laterally extending handle v17 to enable the operative to rotate it and thereby` to clamp the carrier 11 between the extension 10 and the washer 14 through the pressure'exerted by the .spring ring 16.

In order to permit the angular adjustment of the tread rest 5 on the carrier 11 to bring the rest 5 into positions of diderent inclinations to the plane of rotation of the tool the upper end of the tread rest 5 is provided with a shoulder 18 arranged to engage the lower face of the carrier 11 and it also carries a bolt 19 which extends through a hole 2O formed in the forward end of the carrier 11. The tread rest 5 is frictionally clamped to the carrier 11 bymeans of-a stiff spring 21 encircling the bolt( 19 and maintained normally compressed between the bottom of a recess 22, formed in the carrier 11, and a washer 23 interposed between the spring and the head of the bolt 19. With this construction the tread rest 5 is normally held in fixed position on the carrier 11, but by inserting a lsuitable adjusting pin (not shown) into a hole 24 bored in the tread rest 5 the rest may be angularly adjusted into any desired position of inclination to the plane of rotation of the tool.

As customary in machines for burnishing the heels of boots and shoes the machine of the drawings is provided with means for supplying wax to the face of the rotary tool 1. rIhe means shown comprises a wax reservoir 25 in which a supply of wax is kept melted, a rotary disk 26 for transferring the melted wax from the reservoir to the tool 1, and a reciprocating brush 27 for spreading the wax over the working face of the tool. During the operation of the machine the wax is delivered upon substantially the central portion of the working face of the tool as the latter rotates in the direction vof the arrow, Fig. 1, but this wax is not spread over the working face of the tool until the wax covered portion of the tool reaches the spreading brush. The tool usually is of a frusto-conical shape and its rotative movement causes the wax to travel toward, and frequently to iy o, the larger end of the tool before the brush 27 has an opportunity to spread it over the face of the tool. In order to catch the wax thrown 01T the tool in this manner, the machine shown is provided witha splash guard 28 secured to the collar 7. This guard consists of a plate curved about the periphery of the tool 1 and has a width suilicient to cover a considerable portion of the working face of the tool at its larger end. The ends of the guard terminate adjacent to the wax delivery and wax spreading points respectively.' To permit theV operation of the brush 27 the guard 28 has a piece 29 struck up from its body to form a slot 30 through which the brush may project.

In order to return the wax collected on the splash guard to thewax reservoir, the end of the guard adjacent the wax delivering point is provided with an extension plate 31 having a slot 32 formed therein enabling it to straddle the disk 26. The plate 31 has its end portions on opposite sides of the slot 32, bent upwardly to form troughs 33 each inclined toward the disk 26 and serving to conduct the wax collected on the splash guard back to the wax reservoir.

As well known to those skilled in the art the wax reservoir 25 and wax delivering disk 26 are usually adjustable longitudinally of the axis of rotation of the tool 1 to cause the disk 2G to deliver wax to the central portion of the working face of the tool. To permit the plate 31 to follow the adjustment of the wax reservoir and wax delivering disk the extension plate 31 is provided with a slot 34 (see dotted lines, Fig. 1) through which extends a bolt 35 carried by the guard 28. To lock the extension plate in adjusted position the bolt 35 carries a wing nut 36 arranged to clamp the plate 31 to the guard 28.

lVhile the invention has been illustrated and explained in its application to a burnishing machine it will be apparent that some of the features of the invention may be embodied in machines for performing other operations upon a shoe.

I do not claim lherein the novel tread rest disclosed, since I have claimed it in my application No. 865,505, filed October 7, 1914-, which is a division of this application. Y

It will also be apparent to those skilled in this class of machines and with the general objects of the present invention in view, that many changes may be made in the details of construction without departing from thespirit of the invention.

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

A machine for operating upon shoes, having, in combination, a rotary wax applying tool, a wax reservoir, means for withdrawing wax from thereservoir andV delivering it to said tool, a splash guard for collecting the wax thrown o the tool by centrifugal force, and a device for conducting the wax collected on the splash guard back to the reservoir, substantially as described.
