SAW-SWAGE.

SPECIFICATION forming part of Letters Patent No. 297,698, dated April 29, 1884.

To aZZ whom it may concern:

Be it known that I, SIMON KINNEY, of the city and county of San Francisco, and the State of California, have invented an Improvement in Saw-Swages; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful saw-swage of that class in which, through compound levers, power :is acquired to operate clamping devices to hold the sides of the tooth, and pressure devices to swage it.

My invention consists in peculiar swaging devices, and in the means for operating both them and the clamping devices, together with minor details, all of which I shall hereinafter fully explain.

The object of my invention is to provide a machine adapted to receive, clamp, and swage a saw-tooth to the best advantage and with small exercise of the original power.

Referring to the accompanying drawings, Figure 1, Sheet 1, is a perspective View of my saw-swaging machine. Fig. 2, Sheet 2, is a rear elevation of same. Fig. 3, Sheet 3, is a perspective view' of the bed-plate, the faceplate being removed to show the clamping and swaging devices. Fig. at is an end elevation of the machine- Fig. 5 is a detail of the end of the die-lever, the anvil, and the stop.

Ais the bed-plate, faced by a heavy plate, 13, which is spaced from the bed-plate by the intervention of blocks a,Figs. 1, 3, and is properly bolted thereto by bolts a. The bed-plate is bolted to a suitable standard-foundation, C, in the position shown in Figs. 1 and 4.

Into the face of the bed-plateis let a stationary clamp or shoe, D, and through the face-plate is inserted a sliding clamp-bar, D, the end of which is corrugated, and is adapted, when forced inwardly, to bind or clamp the saw-tooth between itself and shoe D. This clamp-bar D is held out away from the shoe D by means of a spring, d, Figs. 1,4, operating against a small lug thereon.

Under the sliding clamp-bar or vise is a bar,

- E, forming the anvil, upon which the sawtooth rests. This anvil-bar is flattened on top and extends through the face-plate and bed- Applicaiion filed August 4, 1883. (No model.)

plate in a socket, in which it may be turned slightly by means hereinafter described.

F is a lever pivoted between the two plates by a bolt, f, Fig. 3, and adapted to play be.- tween the space-blocks at. end of this lever is curved, as in Fig. 5, and forms the die, which bears down upon and .swages the saw-tooth between itself and the anvil-bar.

G, Figs. 3, 5, is a stop curved about the semi-circumference of the anvil-bar, and partly lying in the curved end of the die-lever F. It is secured to said lever by a spring, g, which permits it to be forced back by the tooth when necessary, but which normally holds it in position as a stop or limit to the entrance or insertion of the tooth. -A small set-screw, g, the end of which impinges against the anvil, enables me to make any adjustment of the stop, forward or back, which maybe required. When the saw-tooth is inserted, its sides .are first clamped by the vise, consisting of the two clamps, and then the short or die end of the lever F is forced down upon its edge with sufficient pressure to swage it. This is the general operation; but it will be observed that a peculiar advantage follows the operation of this die-lever, by reason of its pivot-point, which, while its end is being forced down, causes it to describe a small are or curve,

which draws upon the tooth in the direction the insertion of the tooth, and clearing itself when the lever is pressed down.

The short or inner I shall now describe the means by which I r ,H, between which is secured a pivot-shaft, h,

upon which is mounted the main operatinglever I. This lever extends below as well as above its axis, as seen in Fig. 1. It carries a cam, J, Figs. 1, 4,upon which a roller, K, on the end of a bar, L, impinges. The other end of this bar is pivoted at Z to a bearing on the face-plate, and impinges against and holds the outer end of the sliding clamp. Upon drawi ng back the lever I, it forces inward the bar L against the end of clamp D,which binds upon and holds the side of the tooth. This action takes place at once upon the movement of lever I. A set-screw, m, through the bar L, is made to impinge upon and adjust the movement of the sliding clamp.

To the lower end of lever I is pivoted a slotted arm, M, by means of a bolt, a, passing through its slot. The end of this arm is pi"- oted to aswinging arm, N, in the end of which is also pivoted an arm, 0, the upper end of which is pivoted in a block, 1, Fig. 3, in which the end of die-lever 1* is pivoted.

By reason of the slot in the arm M the movement of lever I, which first affects the clamp D, does not at once affect the die-lever; but as soon as the end of the slot is reached the arm M is raised, forcing back swinging arm N, raising arm and block I, and lifting up the end of lever F, which action forces down its die end to swage the tooth. Great power may be gained by this combination of levers. It may be necessary to adjust the width of the opening between the anvil and the die-lever to admit of larger or smaller teeth. The means I employ are shown in Fig. 2. The anvil-bar extends through the back of the bed-plate, and has keyed upon ita lever, Q, the end of which is set by two screws, passing through lugs q on the back of the bedplate. By properly adjusting these screws the anvil-bar may be turned slightlyto incline its flat upper surface more or less,for the pn rpose designated.

In constructing these machines I deem it preferable to make both ends of the lever F alike, in order that it may be reversed to utilize either end as the swagedic.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a saw-swaging machine, the clamp or shoe D and sliding clamp D, by means of 5 which the sides of the tooth are held, the anvilbar E, and pivoted lever F, in combination with the stop G on said anvil and die-lever, and secured to said die-lever by a spring, g, substantially as shown, and for the purpose described.

2. In a saw-swaging machine, the plates A B, spaced-by the blocks a, the stationary clamp or shoe D, and sliding clamp D, in combination with the lever I, havingacam, J, and the swinging or pivoted bar L, havinga roller, K, substantially as shown and described.

3. In a saw-swaging machine, the plates A B, spaced by the blocks a, the former having the stationary clamp or shoe D, and the anvilbar E, having a flattened upper surface, in combination with the sliding clamp D, the pivoted die-lever F, the clamp D being adapted to be operated by the lever I, having cam .T, the pivoted bar L, having roller K, and means for operating the die-lever after the operation of the clamp, consisting of the arm M, lever I, arms N O, and block P, all arranged and operated substantially as herein described.

4:. In a saw-swaging machine, the spaced plates A B, anvil-bar E, the die-lever F, pivoted to said plates, and adapted to swage the tooth by means of the fulcrumed lever I, arm M, swingingarm N, arm 0, and block I, all arranged and operated substantially as described.

In witness whcreof I have hereunto set my hand.

SIMON KINNEY.
