IMPROVEMENT lN SAW-SWAGES.

Specification forming part of Letters Patent No. 210,127, dated November 19, 1878; application filed July 8, 1878.

To all whom it may concern:

Beit known that I, SIMON KINNEY, of Bay City, in the county of Bay, in the State of Michigan, have invented certain new and useful Improvements in Saw-Swages; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of this invention is to cause the swaging of a saw-tooth to be more eft'ectually performed by the operation of a lever mechanism; and my invention consists in a peculiar construction and combination of parts, which will first be described,and then pointed out in the claims.

Figure l is a side view of my improved swage. Fig. 2 is a plan view of the bed detached from the lever mechanism.

The frame is composed of a bed, A, to which a cap, B, is secured by bolts passing through the holes a a, said cap cast with a vertical standard, C, to which is fulcrumed the main lever D, connected by a horizontal lever, E, to the top end of a post, F, the lower end ot' which is pivoted in the bifurcation c in the bed-plate by a horizontal pin, G.

H is a horizontal clamp-plate, secured to the bed A, and I a clamp, sliding vertically in the cap B, to hold the saw-tooth interveningly when the clamp I is forced down by a cam-arm, J, one end pivoted to the standard C and the opposite end beveled to engage with a roller, K, pivoted to the post F, so that when the lever D is depressed the cam.- arm J is moved downward, thereby causing the clamp I to descend. Z1 is a set-screw in the cam-arm J, above the head of the clamp I, to adjust the length of the stroke of its depression according to the thickness of the saw-plate. L is a spring to raise the clamp I after the pressure thereon has been removed.

M is the anvil-bar, adjustable vertically in the base A and cap B, and held tixedly by a suitable key. The anvil M is iiattened on the side in juxtaposition with the clampI, and has a recess of the width of the thickness of a saw-plate, which recess is brought to a level with the plate H when hooked teeth are to be swaged; and when straight teeth are to be swaged the anvil M is adjusted so that the recess shall be below the plate H, whereby the saw-tooth will be pressed against its plain face.

Nis a guide-block, held in contact with the anvil M by a spring, O, and it has a screw, d, to adjust it to snit the saw-tooth, so as to stop at the required place. This guidebloek is caused to recede from contact with the anvil M by the swage when it is advanced to its work by the pressure or" the block R, the spring O being forced back by the same operation to allow of such backward movement.

P is a ilat plate, secured to the bed by bolts c c or other means, and lies in a recess in the cap B, for the purpose of holding` the underlying swage-block Q, in place when the pressure of the levers is on the side clamps H I, which pressure causes the cap B to slightly yield or spring from the base A during the swaging operation. The swage-block Q bears on a recess in the base A, and is retrograded, after swagin g pressure is removed, by a spring, f. The swage-block is constructed oi' upper and lower plates, and an intervening bar, g, having a beveled swaging end integrally formed or bolted thereon.

R is a block lying loose between the upper and lower plates of the block Q, so as to allow of a thin packing, g', to be inserted between it and the swage-bar g. S is a knuckle-block between the block It and post F, so that when the lever D is depressed the post F is drawn inwardly, and causes the knuckle S to push against the block It, and thus thrust the swage-block against the saw-tooth inserted against the anvil M.

In operation, the .depression of the lever D slightly moves the post F, which causes the cam-arm J to move downward by the roller K pressing on its beveled end, and forces the clamp I to hold the saw on the clamp H Xedly. The roller K then passes on top ot the cam-arm J without relaxing its pressure thereon, and the continued movement of the post F acts on the knuckle S and forces the swage-block Q, by its bar g, to swage the sawtooth against the anvil M.

I claim as my invention- 1. The combination, with the base A, 112W- d, sWage-blocl; Q, and clamps H I, arranged ing; @lmnp-plate H, and cap B, having stzmdand operating' substantially ns and for the ard C, of the cam-arm J, post F, roller K, link purposes set forth.

E, and lever D, to operate the clamp I, the SIMON KINNEY. songe-block Q, and n-nvil M, as set forth. Titnessesz 2. The combination of the vertically-zuljustl. B. ZEIGLER,

able anvil M, guide-block N, spring O, screw J. F. LANG.
