AND HERDMAN MOKAY, OF SAME SPECIFICATION forming part of Letters Patent No. 508, 544, dated Novernber 14, 1893. Application filed August 10, 1893 Serial No. 482,801- (No model.

To all whom it may concern:

Be it known that I, THOMAS B.l IUns"r1s,ef Boston, 1n the county of Sufiolk and State of Massachusetts, have invented a new and use ful Machine for Making Toe-Oalks for Horse 1sfhoes, of which the following is a'specificaion.

It is well known to those skilled in the art to which this invention relates, that the short piece of steel which constitutes the toe calk is provided with a spur at one end which is driven into the heated shoe and serves to hold the calk in its proper place until the calk and shoe are welded together.

The spur has heretofore been forged upon one end of the calk by hand and the object of this invention is to provide a machine for forming the spur and severing the calk from its stock with the expenditure oflittle time and labor.

One feature of the invention is the combi stock from which the calk is made; Fig. 2 a detail of the finished calk; Fig. 3 a side view of the machine; Fig. 4 an end view of the same looking in the directionof arrow 4t,Fi 3. Fig. 5 is a view of the opposite end; Fig. 6 a plan view; Fig. 7 a partial section on line 7 -7 of Fig. 6; and Figs. 8 and 9 details of two of the cams. v

The driving shaft or has a pulley a, and pinion a? driving gear b of cam shaft 12 which is supported by hangers c c from bed 0. A frame at is secured upon bed 0 and supports the fulcrums of levers e, f, g, h, and 2'. The periphery of cam 12 moves lever g which carries the adj nstable clamp g, link and pawl g presently to be described. A roll I) on cam b moves lever 'i which carries shears t" by whichthe calk is severed from the stock. Gain 12 has four swells and operates lever e anvil.

securely upon the anvil.

on which is mounted the movable rest 6'; cam b has four swells of increasing radii to impart a greater thrust to die f upon each movement toward the rest 6. Cam I) is a disk with the swells b upon its face actuating lever h which carries die h. Levers g and h are retracted by springs s and s and levers e and f are connected below their fulcrums by coiled spring 8 to maintain the 19- vers in contact with their cams. Frame cl has an upright 01' which supports the anvil k and a stop or guide is which overhangs anvil k and is secured by bolts k which also secure anvil la in place. A plate t is supported by bolts 11 upon upright d and this plate constitutes the secondmember of the shear 77.. A plate m slides in a groove on the upright d, and is held in place by pin m and retracted by spring m when released by pawl g after the pawl has been actuated by clamp lever gto displace the finished calk from the The calks are usually made from a strip of steel of the proper shape and this strip is laid upon anvil it. The mechanism being in operation, the clamp g descends and holds the strip. The rest 6' and die f then move together, die f pressing the material out from the end or the steel strip. The rest e and dief then separate'and die it acts upon the end of the strip to point the spur u. The rest 6 and die f acts four times, die f entering the'steel a little farther at each stroke, and die h acting three times.

'When these dies have completed their work shears t" act to sever a sufficient length from the strip for a calk and as lever g recedes, pawl g pulls plate m with it, pushing the calk ofi of the anvil whence it falls into a proper receptacle underneath the machine. A stationary cam m raises pawl g and plate m returns to its first position.

It will be observed that levers f and 72 are fulcrumned at some distance from the anvil and this is a feature of my invention because the dies are thus caused to travel downwardly when acting upon the material of the calk and the spur is thereby more readily drawn down from the body of the calk instead of relying entirely upon the inclination of the faces of the dies to effect their purpose.

What I claim is- 1. In combination a moving rest; a clamp and a pair of dies acting respectively upon the sideand end of the bar, substantially as and for the purposes described.

2. In combination a clamp; a moving rest; a pair of dies acting respectively upon the side and end of the bar and a severing device, substantially as and for the purposes described.

3. In combination, an anvil; a clamp; a inovable rest and die opposed to each other and THOMAS B. HUES'IIS.
