To @ZZ zowm, it 12a-Cty concern:

Be it known that I, CHARLES J. ADDY, of Malden, county of Middlesex, aud State of Massachusetts, haveinvented an Improvement in Burnishingirlachines, of which the following description, in connection with theaccoinpanyiug drawings, is a specification, like letters on the drawings representing like parts.

rlhis invention in machines for bnrnishing boot and shoeheels is an improvement upon the machine shown and described in United States Patent No. 127,414, dated June el, 187,2. In the machine described in the said patent the shoe is oscillated and the burnishing-tool is moved across the heelsedge by hand.

My invention has for its object to automatically operate the burnishing-tool; and my invention consists, essentially, of mechanism, as will be described, to cause the burnishiug-tool to move transversely or horizontally on the heel-edge to polish the same, the said mechanism being made adjustable, so that the bnrnishing-tool may be made to bear upon and polish uniformly heel-edges of varying sizes and shapes.

Figure 1 is a side elevation of aburnishing machine constructed in accordance with my invention, one of the standards being broken off at its upper end; and Fig. 2, a section of Fig. 1 on the line x oJ-,looking toward the left.

The base A, provided, as shown, with two standards or pedestals, A A, to support suitable bearings, o', for the rockershaft c2, and the carriage or jack c, attached to one end of the said rocker-shaft to carry the boot or shoe, are substantially as shown and described in the patent referred to, the said shaft being rocked or rotated by means of a toothed sector, (LX, mounted upon thestudl2 and engaging the pinion a on the rockshaft, the said toothed sector being connected by the link c5 to the crank-pin c (see Fig. 2) oi the crank or disk el, fast on the main shaft B, the latter being supported in suitable bearings, I), and provided. with drivingpnlleys b', the said parts bei ng and operating substantiallyr as shown and described in the said patent.

The standard A has pivoted toit at its top one end of a horizontal bar or carrier, c', extended across the machine and entering between the projected ends 2 of the standard A?.

The carrier c at its front end has pivoted to it, as at c, a tool-carrier, If, provided, as shown, with a longitudinal opening, through which a rod, A5, is extended.

The rod 5, as shown, is reduced in diameter for a portion of its length, as at 6, which latter is extended up through a narrow portion of the opening referred to, and is provided with a pin, t6, extendedthrough slots bin the Sides of the tool-carrier b", only one of said slots being shown in Fig. 1.

The rod 5 has secured to its lower end, as herein shown, by set-screw 7, the iron or other usual burnishing-tool, b", which in operation is normally pressed against the heel bya spring, bl, the latter encircling` the narrow portion 6 of the rod 5, and having one end bearing against the upper wall ofthe opening' through which the rod 5 is extended, the lower end of said spring resting on the pin b5.

The bar or carrier ois recessed at its under side to receive a spring, c2, encircling` a post, c3, extended upward from the standard A2, the said spring normally acting to raise the carrier o. The tool-carrier li' is also pivoted at its upper end, as at d, to a lever, d', having its free end adjustable in a slotted arm of a lever, d2, pivoted at di' to an arm, d", the latter being attached, as herein shown, by screws d5, to an arm or bracket, t, secured to the upright A. 'The lever d2 at one end has a stud, c, (see dotted lines, Fig. 1,) which enters a camgroove. e, in a disk, c2, attached to or forming part of a wornrgear, ci.

The worm-gear c and disk cZ are rotated by a worm, e5, on a shaft, e", having bearings in the arm or bracket al, the said shaft having mounted thereon pulleys f, connected by belt f2 to pulleyj3on the main shaft, there being a fast and slow pulley on each shaft, to produce a fast or slow movement of the mechanism operating" the burnishing-tool.

During the rotation of the worin-gear the lever d is turned on its pivot, the outer periphery of the cani-groove acting on the stud e, and as the said lever is turned on its pivot the tool-carrier b'i is rocked or moved forward and backward on the pivot o through the lever d', the backward and forward movement of the tool-carrier causing the tool to travel laterally or substantially horizontally over the IOO heeledge of the boot or shoe held in the jack, as hereinshown, by the screw l0, the tread of the heel resting against `the pattern-plate 7L of the said jack.

By adj ustiug` the free end of the lever din the slotted arm of the lever d by means of the setscrew 8, the stroke of the burnishing-tool b laterally over the heel-edge may be varied, so as to enable -heels of various heights or sizes toV beburnished or polished uniformly and equally well.

In operation theboot orshoeisjacked and the burnishing-tool is brought down incontact with the heel-edge bythe operator pressing upon a foot-lever, h', fuloruuied to the base A and connected to the carrier c by rods 71,2, as in the patent referred to, the said foot-levcr having erected upon it a shipper, if, to ship the belt from the loose to thefast belt-pulley as the carrier is depressed. The foot-lever is maintained depressed and in operative position by means of a catch or stop, herein shown as a rod, 7.

The pivotal point d3 of the lever d2 and the slot in the said lever are all so constructed and shaped that in any adjustment the stroke of the tool-carrier and tool is such as to always come back to and stop at the patternplate, against which the tread end of the heel rests, or, in other Words, the inward stroke of thetool b3 is always to the same point; .but its outward stroke may be varied more or lessby altering the position of the set-screw 8 inthe slot of the lever d2.

1.l In a machine for burnishing heels of boots and shoes, the jack or carriage and means to oscillate it, a burnishing-tool, a4 pivoted car-` rier therefor, a cani, `andnieans, substantially i cillate it, a burnishing-tool, a carrier `for it, a

lever, c, on Whiehlthe said carrier is pivoted,

an'd means, substantially as described, to depress the said lever to force the tool against the heel/combinedwith the lever d" and with a 11 second lever having one end secured to the pivl oted toolcarrier and its other end adjustable on the llever d2, toopcrate substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES J ,i ADDY.`
