HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,930, dated July 19, 1887.

Application filed December-27, 1886. Serial No. 222,586.

To all whom it may concern.-

Be it known that we, JOHN H. CONNOR, THOMAS F. BLESSINGTON, and STEPHEN G. BLESSINGTON, of Havcrhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements 1n IIeel-Burnishing Machines, ofwhich the following is a specification.

This invention 'relates to heel-burnishing machines in which a burnishingtool is supported by an arm or holder attached to an oscillating shaft, whereby the tool is reciprocated in the are of a circle of smaller diameter than the width of the heel, the tool being provided with a yielding movement, whereby it is enabled to conform to the curvature of the heel. A familiar example of this class of machines is the so-called Tapley Heel-Burnishin g Machine.

In particular our invention relates to a machine of this class in which the burnishing tool not only reciprocates in the are of a circle, but yields to conform to the curvature of the heel, and also rotates on its own axis while re- 2 clprocatlng.

Our invention consists in the improvements in machines of this class which we will now proceed to describe and claim.

Of the accompanying drawings, forminga part of this specification, Figurel represents a side elevation of a heel-burnishing machine embodying our improvements. Fig. 2 represents a perspective view of that part of the machine to which our improvements are confined. Fig. 3 represents an enlarged side elevation of the part shown in Fig. 2. Fig. 4 represents a sect on on line as m, Fig. 1. Fig. 5 represents a section on line 9/ 3 Fig. 1.

The same letters of reference indicate the same parts in all the figures.

In the drawings, or represents the stand or pedestal, having arms I) b at its upper end,conraining bearings in which is journaled ashaft, c. Said shaft is rocked or oscillated in its bearings by any suitable mechanism, that here shown being a lever, (I, mounted to oscillate on a stud, e, on the standard a, and provided at its upper end with a segment-gear, f, meshing with a pinion, g, on the rear end of the 50 shaft 0, as shown in dotted lines in Fig. 1.

The lever (Z is oscillated, and. thus caused to (No model.)

rock the shaft c, by a connecting-rod, i, jointed to the lower end of said arm, and a powerdriven shaft, j, having a disk, It, on which is an eccentric wrist-pin, Z, engaged with said connecting-rod.

The mechanism thus far described is substantially the same as that embodied in the well known Tapley machine, and of itself forms no part of our invention.

m represents an arm affixed to the shalt c, and projecting laterally therefrom. The outer end of said arm is formed as a guide to hold and permit the sliding movement of a box or bearing, n, in which is journaled a shaft or spindle, 0, carrying at one end a burnishingtool, 1).

q represents another arm affixed to the shaft 0 at a suitable distance from the arm or and bifurcated, as shown in Figs. 2 and 4. Said bifurcations receive trnnnions r r on a swiveled bearingbloek, s, in which the burnishen spindle 0 is journaled.

The swiveled bearing 3 is formed as a frame surrounding an opening, which receives a pinion, t, affixed to the burnisher-spindle, said spindle having its bearings in two of the side pieces of the swiveled bearing.

it represents an internal gear-segment meshing with the pinion t and affixed to the standard a, preferably by means of a socket, a. formed on the rear side of said segment and fitting upon and screwed to one of the arms b. (See Fig. 5.)

It will be seen that the rocking motion of the shaft 0 causes the arms M q, carrying the burnisher-spindle, to oscillate and reciprocate said spindle and the burnishing-tool in the arc of a circle. It will also be seen that the engagement of the pinion on said spindle with the fixed internal gear, a, causes the spindle and burnishingtool to rotate while reciprocating, the direction of the rotary motion being opposite to that of the progressive motion of the tool, each reversal of the progressive mo -tion of the tool being accompanied by a re- IOO ture of the heel, which generally varies from the arc of a circle.

The spindle and tool are pressed inwardly to give the toolthe required degree of pressure on the heel by springs 10, each attached at one end to a counter-balance, m, on the arm on, and at the other end to an arm or lug, a, on the sliding box it.

The boot or shoe is supported by ajack during the burnishing operation. Said jack, as here shown, does not differ from the jack used with the Tapley machine, and, as it forms no part of our invention, need not be here described.

lVe prefer to-give the teeth of the pinion t on the tool-carrying spindle a convex curvature and the teeth of the fixed internal gear a corresponding concave curvature, so thatthe outward and inward swinging movements of the spindle will not effect the engagement of the pinion and gear.

Our improvements, as here shown, are capable of being applied to the oscillating shaft 0 of the Tapley machine without any change in the construction of the machine excepting the removal of the-non rotating burnishing-tool and its supports from said shaft and the substitntion therefor of the arms on and q and their bearings n and s and the tool carrying spindie 0, and the attachment to the standard a of the fixed internal gear, a.

It is obvious that various changes may be made in the details of construction without departing from the spirit of our invention.

' We prefer to limit the inward movement of the burnishingtool, caused by the. springs 10, by adj ustablc devices, so that the tool may be adjusted to different sizes of heels. To'this end we provide the sliding hearing it with a lug, a, in which works an adj listableset-screw, I), arranged to bear in a lug or projection, c,

- on the arm m, said lug and screw constituting an adjustable stop. WVe also prefer to make the tension of the springs 10 adj ustablc to increase or diminish the pressure of the burnishing-tool on the heel, or to permit the tool to yield or move outwardly without an undue increase of pressure when used on larger heels. This adjustment of the springs We effect in the present instance by forming the eyes with which the ends of said springs are engaged on rods d cl, which are adjustable in the lug n andcounter-balance mrby means of nuts on the threaded outer ends of said rods or in any other suitable manner.

The counterbalance m on the arm at may be formed in a single piece with the similar counter-balance, g, on the arm 'q, as indicated in dotted lines in Fig. 3.

silt

posed. to makea burnishingmachine havinga rotating wheel which is carried back and forth over the heel and has its rotation reversed with each reversal of its progressive movement; hence we do not claim this, broadly, as our invention;

We claim- 1. The combination of the oscillating shaft having arms or holders in q, the sliding hearing it and the swiveled bearings, supported, respectively, by said arms, the tool-carrying spindle journaled in said bearings and provided withapinion, t, the fixed internal gear, 9', meshing with said pinion, and a spring or springs, 10, whereby the sliding bearing is pressed'i'nwa-rdly, as set forth.

2. The combination of thesupportingstandard having the arms I) I), the internal gear, it, having upon its rear side a socket, a, formed to receive one of said arms, the oscillating shaft 0, journaled in said arms, and the shaft 0,

journaled in bearings supported and oscillated by the shaft 0, and provided at one end with a pinion, t, meshing with'the said internal gear and at the other end with a bu'rnishingtool, as set forth.

3. The combination of the tool -carrying spindle 0, oscillating shaft 0, arms m q, pinion t, and fixed internal gear, a, the swiveled bearing s and the sliding bearing a for said spindle, the springs 10 w, whereby said bearing a and spindle 0 are drawn toward the center of said are, and adjustable devices, as the lug c and screw 1), for arresting the inward movement of the spindle, as set forth.

4. The combination of the tool-carrying spindle, the means for reciprocating the same in the arc of a circle, thesliding bearin'gn for said spindle, the springs 20 10, whereby said bearing and spindle are drawn toward the center of said are, adjustable devices, as the lug c and screw 1), for limiting the inward movement of said spindle, and adjustable devices, substautially as described, whereby the tension of thesprings may be adjusted to correspond with variations in the limitation of the inward movement of the spindle, as set forth.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 18th day of December, 1886.
