HEEL-BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,480, dated December 5, 1882.

' Application filed April 24, 1882. (N0 model.)

To all whom it may concern:

Be it known that I, WILLIAM GORDON, of Boston, in the county of Suii'olk and State of Massachusetts, haveinvented certain Improvements in Heel-Bnrnishing Machines, of which the following is a specification.

This inventionconsists, first, in producing a heelburnishiug machine with atool having a substantially vertical burnishing-face and a substantially vertical reciprocating movement, so as to enable the operator to hold the boot or shoe without the use ofajack and present the heel to the best advantage to the burnishing-tool.

a The invention consists, secondly, in the provision ot'a rest under the tool adapted to support the heel while it is being acted on by the tool, as I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a heel-burnishing machine embodying myinvention. Fig. 2 represents a side view of the head of the machine enlarged. Fig. 3 represents a top view of the same. Fig. 4 represents a section on line am, Fig. 2.

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

In carrying out my invention I provide a suitable standard ort'rame to supportand mechanism to operate a buruishing-tool, A. Said tool has a substantially vertical burnishingface, a, and a verticallip, a, at the edge of said face, and is adapted to reciprocate vertically, or nearly so. This arrangement of the burnishing-face and lip and the direction of the movement above described enable the operator to watch the burnishingface of the tool during the operation, so that hecan see that the work is being properly performed, and also to hold the bed in a vertical plane and press it horizontally againstthe burnishing-face ot'the tool,

so that his own weight can be utilized in exerting the desired pressure.

The means for supporting andreciprocating the'toolmay be variously modified without departing from the spirit of my invention. In the present instance the tool is mounted on a frame, 0, pivoted at D D to fixed standards E E, and adapted to oscillate vertically. The frame is oscillated by an eccentric, F, on a shaft, G,journa-led in hearings in the post H,

said eccentric bearing on cross-bars i i of the frame G. The shaft G is provided with apulley, J, which is belted to a driving-pulley, K. L L are guides to prevent the lateral movement of the burnishing-tool.

The improved arrangement and direction of movement of the hurnishing-face is especially adaptedfor heel-burnishing in which the work is performed without lateral movement of the heel in a direction at right angles to its tread or bottom surface. Hence no particular ditficulty is experienced in keeping the bottom of the heel against the lip of the tool. The same arrangementand direction ot'moveuient would not be'applicable to sole-edgeburnishing machines, because the curvature ot'a sole is such that nearly or quite as much effort is required in keeping the bottom of the sole in contact with the lip as in keeping the edge ot'the sole in contact with the burnishing-t'ace. Hence in sole-edge-burnishing machines employ log areciprocating tool without a jack the tool is always reciprocated horizontally, its burnishingface and lip being substantially horizontal, so that the operator can exert at the same time an upw'ard pressure on the burnishing-l'ace and an inward pressure on the lip. While thelastnamed arrangement and movement of the tool is the best that is known for sole-edge burnishing, it is not suitable for heel-hurnishing for the following reasons: First,the bottom surface of the heel which is pressed against the lip is more abruptly curved at its margin, so thatit would be easily displaced and caused to slip oflf the lip by the horizontal movement of the tool and, secondly, the operators weight cannot be utilized in pressing the edge ot' the heel againstthe burnishing-t'ace; third,theburnishing-l'aceisnot visible to the operator during the operation.

It will be observed that by reciprocating the tool vertically liability of the bottom of the heel slipping oft from the lip of the tool horizontally is mainly avoided, there being no horizontal change in the position of the lip or tool.

R represents a. fixed rest, which is suitably attached to the standard H, and projects under and in front of the operating-face of the tool A,

so as to form a support for the heel while the latter is being acted on by the tool, and prevent the heel from slipping downwardly from the tool. The rest is preferably a metal arm, and the portion of it on which the heel hears is preferably eonvexed and smoothly finished.

It will be seen that the rest enables the operator to exert his whole force in pressing the heel against the tool, no effort being required by him to prevent the heel from slippingdownwardly, as it would naturally have a tendency to do ifthe rest were not employed.

I claim 1. In a bnrnishing-machinc, the bnrnishingtool A, the burnishing-face aand lip a of which are in a substantially vertical plane, combined With the tool-carrying frame 0, having the horizontal pivots D D and cross'bars I I, and the operating-eccentric F, arranged upon a driver-shaft, G, to impart to said frame a vibratory movement in a vertical plane, substansesame tially as shown and described, and for the purpose specified.

2. In a heel-burnishing machine, the frame supporting the bnrnishing-tool and the devices for reciprocating it vertically, and provided with a fixed rest, R, extending outward below and beyond the tool, and adapted to afford a bearing beneath for the heel in a line with the path traveled by the tool and beyond the outer face of the latter, as specified.

In testimony whereofl have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of April, 1882.

WILLlAM GORDON.'
