EDGE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No, 285,303, dated September 18,1883.

Application filed January 19, l8ii3. (No model.)

T aZZ 2071/0/12 it may concern.-

Be it known that I, Enos PATTEN, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Edge-Setting Machines, of which theffollowing, taken in connection with the accompanying drawings, is a specification.

This invention relates to that class of machines commonly used for the purpose of burnishing the edges of boot and shoe soles and heels.

The invention consists in the details of construction and in the arrangement of the varirious parts, as will now be fully described and specifically claimed.

In the accompanying drawings, Figure 1 gives a perspective side view of a machine embodying my invention. Fig. 2 is a front view of the tool-bearing head and its component parts, while Fig. 3 illustrates the method of attaching the tool toits carrying-shaft.

The shaft A is supportedby and adapted to turn in the frame-work B. It is provided with a pulley, (not shown) to receive the drivingpower of the machine applied in the usual and obvious way, and it is also provided with a fixed pulley, O. Said pulley O is connected by suitable belt, a, to a pulley (not shown) on the shaft D, which shaft D is arranged to turn, as represented, in the frame E, and said frame E is arranged upon and supported by a second 'frame, F, which in its turn is mounted on the shaft A, so as to permit of being tipped or oscillated thereon. Said frames E and F are connected together by means of a swivel-pin, I), so as to allow the frame E to be turned slightly in reference to frame F, while a counter-weight 011 thebottom end of frameF servesto keep the same in a nearly vertical position normally.

So much of the machine as is thus far described is found in those machines heretofore in use, and is not therefore of my invention;

stiffness and lack of flexibility in the movements thereof. The effort was made to avoid this by using in place. of the belt a jointed metallic arm-connection, reaching from the shaft D to the tool or tool-bearing shaft in the head. This resulted in a machine having less vibration and jar in, the head, but which must necessarily be worked at a less rate of speed on account of the wear and liability to break the jointed arm-connections. To construct a machine having all the desirable features of these two styles of construction, and at the same time to obviate the undesirable qualities there of, is the main object of this my present improvement. To that end I locate the toolbearing shafte in a suitable head having a rearwardly-extending arm, f, and in the rear end of said arm f is a shaft, 71 carrying pulley m. Said shaft is further provided with an ordinary eccentric and pitman-rod, 1-. The opposite end of the pitman r is connected to pin s, which projects into the tool-bearing shaft 6. Motion is transmitted from the pulley d to the shaft h by means of belt I, and from this shaft 71/ motion is transmitted through the pitman 9' and pin 8 to the toolbearing shaft 6, so as to oscillate in its bearings while the shaft h re.- volves.

The tool-bearing head is connected to its supportingarm H by means of pin joint R, and permits of being slightly turned to either side in an obvious manner. fore end of the tool-bearing head is a rod, T, adapted to reach forward and bear against the arm of the operator while he holds the handle 3, and so assists the workman to steady and manipulate the machine. The supporting- Attached to the arm H is suspended at its rear end from the 6. The inner ends of said latches are pivoted.

to the shaft 6, while their outer ends project slightly beyond the end of the shaft. The spiral spring 7, arranged, as represented, between the latches, operates to open or expand their outer ends, as in Fig. 8, to hold the burnisliertool 2.

The burnisher-tool 2 consists of a small inetallic button having its working-faces shaped in the usual manner, and is provided with a central longitudinal bore, to receive the end of the shaft 0. The tool, when slipped onto the end of the shaft 6, is retained in position by the latches 6 6, as shown in Fig. 3. The hole in the tool for receiving theshaft e is made tapering, its inner end being larger than the shaft 0, so as to permit of certain loose motion, so as to adapt itself while in operation to the curves and inequalities of the sole-edge.

The operation of the machine is similar to those now in use, and will be obvious to those skilled in the art.

I claim and desire to secure by Letters Patent 1. The combination of the shaft 6, latches G 6, suitable means to expand or open the said latches, and the burnishing-tool 2, all substantially as described.

2. The combination, with the shaft 6, of the burnisher-tool 2, having the conical base, whereby it is loosely mounted upon its shaft, for the purpose set forth.

In testimony whereof I have signed this specification.

ENOS PATTEN.
