SAW-SWAGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 355,912, dated January 1], 1887.

Application filed June 4, 1886.

Serial No. 204,148. No model.) Y

T0 at whom it may concern:

Be it known that I, WILLIAM G. BAUM GARDNER, of Filer City, in the county of Manistee and State of Michigan, have invented a new and Improved Saw-Swaging Machine, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved saw swaging machine which is automatic in operation and adjustable to saws of any size or shape.

The invention consists of a sliding swagegate carrying a stationary anvil-die, of an oscillating die operated from the main shaft, of anautomatic clamp-lever, of an adjustable saw-blade holder, and of a device for moving the saw.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my improvement. Fig. 2 is an end view of the same. Fig. 3 is a rear elevation of the same, parts being removed. Fig. 4 is a detail View of the dies and the swage-gate. Fig. 5 shows detail views of the oscillating die and its carrier; and Fig. 6 is a sectional view of the main shaftand the friction-roller operating the swage-gate.

On the main frame A, of suitable construction, is mounted the, main driving-shaft B, rotated either by means of a pulley, O, or a crank-arm, O. The front end of the shaft B is provided with a crank-arm, B, on which is mounted the friction-roller D, operating in the cam-groove E, formed in the swagegate .F, sliding in suitable bearings on the frame A. To'the swage-gate F is secured in an inclined position the stationary anvildie G, of suitable The oscillating die H is held in a head, I, attached to a shaft, I, mounted in a bearing, F, on the swagegate F. The shaft 1-is' provided with a sector-gear, J, which meshesinto a sector-gear, J, secured to the main shaft B, and with a tripping -lug, K, which engages with the arm K, secured to the frame A, and having an upwardly-projecting inclined part, Kfl'on which rests the set-screw .L, screwed in the upper end of the clampinglever L, pivoted on the front of the swagegate F.

The main shaftB is provided with aneccentric, M, having the eccentric -strap M, the lower end of which is pivotally connected with the arm N, secured on the rocking shaft N,

mounted in abearing on the main frame A and carrying an arm, 0, on the upper end of which is pivoted thefeed-arm P,.oneend of which engages with the teeth of the saw V to be swaged, and rests on an arm, Q, rigidly secured to the side ofthe frame A. In suitable bearings on'thefront of the frame A-slides the saw-gage plate R, provided with the adjust= v able cross-head S, which is raised andlowered by the screw T, having a crank-arm, T, and mounted on the frame A. The saw-rest U is also adjustable on the gageplate R. The main frame A is providedwith a set-screw, U, on which rests the swage-gate F when in its lowest position.

The operation is as follows: The saw V to be swaged is placed in the saw-gage plate'R,

and rests with its lower edge on the saw-rest V ,U, the dies H and Gare'set to the shape of the teeth of the saw to be swaged, andthe feed-arm P is adjusted on the, arm 0 so as to move the saw vV one tooth for every revolution of the main shaft B. The stationary anvildie G rests against the front end of the tooth of the saw V, and the lower end of the clamplever L rests on the outside of the tooth of the saw and prevents the tooth from. bending sidewise under the pressure of the oscillating die H when the tooth is swaged. It will be seen that when the main shaft B is rotated the'friction-roller D will raise the swage-gate F, and at the same time the sawV will be moved the distance of one tooth in the direction of the of the tooth by the action of the screw L on the inclined arm K When the swage-gate F is in its lowest position, the sector J on the rewolvingmain shaft 13 engages the sector J on the shaftl, and thereby turns the latter, so that the die If passes over the upper end of the respective tooth of the saw V and swages the same. The swage-gate F is firmly held at rest during this operation and during one-fourth of the revolution of the main shaft B by the peculiar form of the cam-groove E in the swagegate F. The action of the friction-roller D in the cam-groove E then raises the swage-gate F, and the tripping-arm K comes in contact with the lower end of the stationary arm K, whereby the shaft I is turned to its former position and the sector J is again moved to such a position that the sector J will engage the sector J in the next revolution of the shaft B.

The saw V is moved the distance of one tooth by the action of the feed-arm P, as above described, so that the next tooth of the saw is swaged when the swage-gate F returns to its lowest position, as before described. The throw of the arm P can be regulated by the adjustment of its pivot in the apertures O of the arm 0, or by adjusting the pivot of the eccentric-strap M in the apertures N of the arm N.

It will be seen that a saw of any size or shape cl ailn be automatically swaged by my device.

e tooth imparts a very fine steel-drawn temper to the cutting-edge of the tooth.

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 combinatlon of a sliding swage gate carrying a stationary anvil-die, and a clamp-lever with an oscillating swaging-die, substantially as shown and described.
