SQLE OR HEEL BURNISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 276,345, dated April 24:, 1883.

Application filed Febrnary'lQ, 1883. (No model.)

To all whom it may concern:

Be it known that I, HIRAM BOND, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain Improvements in Sole or Heel Burnishing Machines, of which the following is aspecification.

This invention has for its object to provide improved means for supporting and driving a rotary heel or sole edge burnishing tool, and permitting the same to assume all the different positions required to present it properly to all parts of the surface to be acted on.

The invention consists in the improved devices which I will now proceed to describe and claim. I

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation of a burnishing-machine embodying myimprovements. Fig. 2 represents a front elevation of the same. Fig. 3 represents an enlarged section on line at m, Fig. 1.

Fig. 4 represents a section on line y 3 Fig. 3.

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

In the drawings, 0 represents a fixed frame adapted for attachment to a bench or other support.

1) represents a driving-shaft journaled in fixed bearings in the upper part of the frame a, and provided with a fast pulley, c, and a loose pulley, c, for the driving-belt, and with a grooved pulley, d. a

e represents a laterally-movable shaft having on its ends friction-rollers ff, adaptedto run in fixed segmental slots in the direction of the length of the slots, tracks, or guides g g in the side pieces of the frame a. Said slots are segments of a circle whose center is the driving-shaft 1); hence the shaft 0, while it is free to move laterally in said slots, is kept thereby at a uniform distance from the shaft b, so that the belt that connects the pulley d on the shaft b with a pulley, d, affixed to the shaft 0 is not afiected by the movements of the latter. The shaft 6 has no movement in the direction of its own length or crosswise of the slots 9 g. l

h represents the rotary stock or shaft which holds the burnishing-tool i. Said stock is provided with a pulley, l, belted to a pulley, m, on the shaft e, and is journaled in ahead, 12, which is provided with a handle, q, for the operator to grasp, and a 'bail,-r, attached to a spiral spring, s, which constitutes a yielding support for the head and stock. The head 2 and shaft 0 are connected by the following devices, viz: two U-shaped arms, at, journaled, respectively, on the shaft 6 and head 12, and a rod, to, passing through slots aa/ in theouter or swinging ends of the arms a v, and having hooked ends engaging with eyes I) b, attached to said arms inside of the slots to a, as shown in Figs. 3 and 4. The slots 01. a are so formed that they will allow the rod w no vertical play in them, but are elongated to allow said rod a considerable lateral play. This form of the slots and the connection of the rod to the arms a '27 at points inside of the slots at a, or between the slots and the parts to which said arms are pivoted, prevents the arms a '11 from sagging downwardly. The arms a o and rod to constitute a connecting device between the head 12 and movable shaft 6, which causes said stock to move back and forth, said shaft thus keeping the belt that rotates the stock in a uniform state of tension, and also enables the stock to move laterally in a vertical direction and longitudinally in a horizontal direction, and to be tipped or inclined, all independently of the shaft 0, said independent movements being sufficient to enable the tool to assume all the positions required in performing its work.

The toolz' may be of any desired shape, and has a shank which is inserted in a socket in the stock h, in the usual manner.

The boot or shoe issupported by a suitable rotary jack during the operation, and the tool is moved by the operator as required.

I prefer to interpose a spring, 8'', between the arms a o, as shown in Figs 3 and 4, said spring being supported by the rod wand press ing in opposite directions against the arms a 01, thus keepiugthe hooked ends of the rod in in contact with the outer portions of the eyes b, and preventing said ends from rattling or moving in said eyes enough to vary the tension of the belt that drives the tool-stock.

I claim 1. In a burnishing-machine having as elements the driving-shaft b, journaled in fixed bearings, the laterally-movable shaft 2, hav

inga pulley belted to a pulley on the shaft b, the tool-carrying stock h, supporting apulley belted to a pulley on the shaft 0, the head 12, supporting said stock, and connected to the shaft 0 by ajointed connection, substantially as described, the combination, with said elements, of the friction-rollers ff on the movable shaft 0, and the fixed segmental tracks or guides g g for said rollers, whereby the shaft 0 is kept at a uniform distance from the driving-shaft, and is guided in its lateral movements, as set forth.

2. The combination of the movable shaft 0, belted to a driving-shaft, the tool-carrying stock h, belted to themovable shaft 0, the head 4 12, supporting said stock, and theintermediate connecting devices composed of the arms 11-12,.

to this specification,in the presence of two subscribing witnesses, this 14th day of Feb- 25 ruary, 1883.
