EPECIFICATION forming part of Letters'Patent No. 298,484, dated May 13, 1884-.

Application filed October 17, 1883. (No model.) 7

To all whont it may concern:

Be it known that I, ISIDORE LEGAY, of the city, county, and State of New York, have invented a new and useful Improvement in Heel- Burnishing Machines and I do hereby declare that the following is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to that class of shoeheel-burnishing machines. in which the shoe is supported upon an oscillating shaft in suitable position to bring the heel of the shoe in line for contact with an adjustable burnishing or finishing tool.

The object of my invention is, first, to facilitate the attachment of the shoe to the oscillating shaft; second, to produce an automatic bearing of the burnishing-tool upon the heel; and, third, to permit the tool and its guide and frame to be swung out of the way, so that the burnished heel may be readily finished upon the machine by an application of hand-tools where required; and it consists in the construction and adaptation to these ends of the mechanism hereinafter described and claimed. I

In the accompanying drawings, Figure l is a perspective view of my improved machine complete. Fig. 2 is an enlarged view of the burnishing-tool, and Fig. 3 is an elevation of the movable stay-block which actuates the burnisher and its gearing detached.

A A A represent a suitable base and standards, upon which is mounted an oscillating shaft, B. An oscillating movement is imparted to this shaft 13 by means of a cog wheel, 0, fitted thereon, and which is interposed between toothed racksD D, adapted to reciprocate freely between suitable vertical guides arranged on opposite sides of the wheel, and to engage the same. To one of these racks, D, is suspended a weight, D. The lower end of the opposite rack, D, is connected by means of a cord or rod, D with a treadle, E. The pressure of the operators foot, when applied to the treadle IE, will serve to counterbalance the suspended weight D", and to produce, by the operation of the treadle, an alternate reciprocation of the two racks DD, which will operate to produce an oscillation of the shaft B. One end, B, of the shaft is made to project beyond its bearings, and upon this projecting end is fitted a sliding collar, F, carrying a dog or clamping-arm, F, adapted to project beyond the end of the shaft, in line parallel therewith, and which is so bent, as shown in Fig. 1, as to permit of the insertion of a shoe upon the end of the shaft inside of said arm. The free end of the clamping-arm or dog F is carried upward, so as to bring it into line with the axis of the shaft, andit terminates in athreaded nut, F through which works a threaded clamping-bolt, F, whose axis coincides with the axis of the shaft 13. The end of this clamping-bolt F projecting toward the main shaft terminates in a disk presenting a fiat surface perpendicular to its axis. The opposite end of the bolt is fitted with a crank or hand-wheel, F, for its rotation. The sliding collar F, by which the dog or clamping-arm is supported upon the shaft B, is secured, when adjusted, by means of a setscrew, F

The burnishingtool and the movable stayblock by which its position upon the heel is adjusted are supported by means of a frame carried upon the upper free end of an arm, G, pivoted to swing in a plane at a right angle to the axis of the shaft B upon a vertical rod, G mounted upon a standard, G, supported upon the base A of the machine in line with the standards A A, and the oscillating shaft B, supported thereby. The rod G is made adjustable vertically in the standard G by means of a capstan-headed screw, a, fitted to the lower end of the rod with a socket-joint, and which works in a tubular threaded seat or recess in the upper end of the standard. The arm G is guided in its vibration by means of a plate, G, attached at its lower end to the upper end of the vertically-adjustable rod G in a plane at right angles to the axis of the shaft B, and against which the arm swings under a parallel bar, 12, secured to the upper end of the plate, as illustrated in Fig. 1, the

arm being pivoted at its lower end to the face of the plate G", immediately over the top of the rod G", so as to admit of being brought into a vertical. position coincident with the axis of said rod and in line with the axis of the shaft 13, and to swing out thence to an angle of forty-five degrees, more or less. The

a shaft, H, is mounted in suitable bearings.

parallel with the shaft 13, and by the vibration of the arm G this shaft may be brought into a position directly over the prolonged axis of the shaft B. Upon the body of this shaft H is mounted a cog-wheel, I, firmly attached thereto, and the face of this wheel, in line parallel with its axis, is equal to or greater than the height of the shoe-heels to be burnished. The shaft II is adapted to traverse longitudinally in its bearings, and it is threaded at its inner end to engage a threadedseat in its inner bearings, so that it shall be fed for ward or backward therein by its simple rotation. Its rotation is produced by means of a second cogwheel, J, of a larger diameter than the cog-wheel I, and which is mounted in the same frame to gear into said wheel, and is actuated by means of a hand-wheel or crank, J placed upon the end of its shaft.

A stay block or plate, K, is supported upon the ends of two parallel rods, K K, which are arranged to slide in line parallel with the shaft II through bearings in the frame which carries the wheels I and J. This block K is moved backward and forward over the heel of the shoe, when it is clamped to the end of the main shaft B, by the reciprocating movement of the screwshaft II, whoseinner' end engages a socket in the end of the block.

Attached to the frame upon the upper end of the arm G, and projecting upward therefrom, is an arm, L, terminating at its upper end in a threaded nut, L, through which works a transverse bolt, M. Upon one end of this horizontal bolt is formeda hand-wheel,

M, and to its opposite end anannular plate or I disk, M is attached with a pivot-joint. (See Fig. 1.) Through this annular plate M as a collar, a weighted rod, N, passes loosely, and terminates at its lower end in a weight, N, in

the lower side of which is formed a socket adapted to receive the shank of the burnishingtool 0. By an adjustment of the weighted rod N and of the horizontal screw-bolt M the disk M may be brought in proper position over the heel of a shoe clamped upon the end of the main shaft 13, so that the tool will drop and rest automatically with its full weight smooth and the angles neatly rounded, to present a polishing-surface to the heel to be operated upon.

In operating my improved machine the shoe, either with or without a last, is placed over the projecting end B of the main shaft B, with the heel out, and the clamping-arm or dog F is moved inward nn til the disk on the end of its clampingbolt F rests against the outer end of the heel of the shoe. The clampingarm is then made fast by means of the setscrew The bolt F" is then-screwed up until the shoe is firmly held against the end of the main shaft, so as to rotate therewith. If, now, the arm G be swung into position to bring the lmrnishing-iron O, clamped to the weighted rod N, in position, with its V-shaped notch embracing and resting upon the front edge of the heel of the shoe, and the movable stayblock K is carried forward against the lower end of the burnisher O as it thus rests on the edge of the heel, the machine is ready for the operation of burnishing. An oscillating motion being imparted to the' main shaft B by means of the treadle and the racks D D, the shoe is made to rotate reciprocally, the burnisher bearing thereon with its full weight added to that of its weighted rod N. Meantime the burnisher is made to traverse back. ward and forward upon the heel by means of the plate or rest K, which, being carried forward by the rotation of the screw-shaft H through the agency of its operating-wheels I J and crank J will move the burnisher back over the heel, and, being withdrawn, will allow it to slide forward by reason of its weight over the slope of the heel. WVhen the heel is sufficiently polished by the burnishing-iron, the latter is removed, and the arm G, carrying the stay-plate K, is unclamped and swung back out of the way, so that a finishing-tool may be applied by hand to the still rotating heel.

I reserve the right to cover the burnishingtool formed with a V-shaped recess in its lower edge, to rest upon and embrace the curve of the shoe-heel, in a future application for Letters Patent; and

I claim herein as my invention- 1. In a shoe-heel-burnishing machine, the combination, with the oscillating main shaft, of an adjustable shoe clamp or dog fitted upon the end of said shaft by means of a sliding collar encircling the shaft and fixed by a clamping device, substantially in the manner and for the purpose herein set forth.
