Specification forming part of Letters Patent No. 142,756,dated Septemberl, 1873; application filed June 28,1873.

To all whom it may concern.- r

Be it known that I, CHARLES J. ADDY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Machine for Trimming and Burnishing the Edges-of Boots and Shoes, of which the following is a specification:

The nature of my invention consists, first, iu/new devices for holding the shoe while be.

lng operated upon; second, in new devices by which the cutter or burnislier lcan be adjusted to the work to be accomplished.

Figure 1 is a plan of my machine. Fig. 2 is'a cross vertical section of the same. Fig. 3 is a front elevation, showing the burnishing or cutting arbor.

A B represent the frame of thel machine. D and Dl aretwo standards, through centersvof the upper ends of which two arbors pass, said arbors being operated by the gearwheels F and F. At the inner end of the arbor, which passes through D, a crank-arm, E, is attached. From the end of this arm E the lastpsupporter E1 extends andrigidly holds the last E2, as shown in Fig. 1; The arbor that passes through Dl has-a crankarm, E3, anda pattern-supporter, E4. As the arbors that pass through D and D are centered exactly in line with each other,` and are bothdriven .by the shaft H, which acts through the gears El1 H2, O1 G2, F and-F', it will be seen that their movements are precisely the same; hence the pattern attached to the supporter E4 will move in exact accordance with the shoe attached to the last E2. The pattern -supporter E4 slides freely through the arm E5, and is held in position by the pin or key g, which is attached to and swings with the arm G.

To jack a shoe, I remove the pin g, which allows the supporter E4 and pattern E to slide back from the last E2. Now, the shoe may be placedupon the last and the pattern E5 brought Vup against it, where it is held lirmly by replacing the pin g, the pin g being made wedge-shaped, so that it can be pushed in until the desired pressure is exerted against the sole of the shoe. Motion is communicated tothe shalt H hy the pnlcutteror burnisher.

ley Il, this pulley being connected, by a sleeve, 12,'to the pulley I and to the ratchetclutch I3. H3 is a fixed clutch on the shaft H. I4, Figs. .l and 2, is alever arranged tol l operate on the clutch l5. By pulling the np-` per end H5 of the`-lever I4 outward, the 'clutch I3 is made to engage the clutch H3,

`thus causing the shoe and pattern to revolve. This revolution will continue until the shoe gets around into a horizontal position. Then'the pin z' willfall into avnotch in the wheel E5. This will allow the lever I* to spring downward and release the clutch I", and thus stop the revolution of the shoe.

The action ot' the pin c' also serves to hold.- the shoe in position until the presented edge.

is trimmed or burnished. To restart the shoe, I have simply to draw out the upper part H5 of the -lever H4. This will engage the clutch, as before,'and the shoe will con-V tnue to revolve until the other side is pre-- sented to the burnisher. Then the pin t' falls into thenotchprovided for it and the machine which serve --to keep the frame L steadily up to the lever L1. The lever Ll Lz has a counlterpoise, L5, to balance the weight of the burnishing-arbor. The lever L1 LZ L5 is hung on the lowerend of a link, L4, which is suspended from the standard P, so that the lever can be drawn backward and forward to suit the work expected of the cutter or burnisher.

Motion is communicated to the arbor K by a system of belts and pulleys, M N M', Sac. i

The standard P revolves on a vertical axis, P', Fig. 2.

I claim as my invention- 1. 'lhe combination of the clutch ln H5 and the lever I4 115 with the pin 'i and wheel 195,2'

vWedge shaped key g, substantially as described, ztnd for the purpose set forth.

4. The combination of the frame L, springs YS S, and balanced lever Ll L3 with the revolving standard P, substantially as described, and for the purpose 'set forth;
