JAMES- H, BAKER, OF WVESTVILLE, OHI O.

FORGE-HAMMER.

SPECIFICATION forming part of Letters Patent No. 297,659, dated April 29, 1884.

v Application filed October 24, 1883.- (No model.)

die-blocks for forge-hammers; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forth,

and pointed out in the claims.

Reference is to behad to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a perspective view of a die and die-block anvil, anvil-support, and part of the forge-hammer provided with my'improvement. Fig. 2 is'a'side view'of the same, the hammer being omitted.

The die A, which is shaped and formed according to the size, shape, and form that the clip, &c., are to have, is placed on a die-block,

B, and is held on the same by suitable devices. The die-block is provided with track-bars C, projecting from the bottom and sides of the die-block, the lower edges of which track-bars rest on rollers D, journaled in vertically-ado justable brackets E, held on the sides of the anvil I. If desired, the rollers D can be held in grooves in the top of the anvil. and flanges may be provided on the sides of the die-block in place of the bars 0.

On the front of the die-block B a rack, F, is secured parallel Withthe' said front, and in such a manner that the rack projects the dis tance of its width from the front of the said die-block. The rack can be fastened on the die-block in any suitable manner, or can be made integral with the same. A short shaft, G, of any desired length, is journaled in the upper end of an upwardly-projecting arm or plate, H, secured to the front of the anvil I, and on the inner end of the said shaft G a pinion, J, is rigidly mounted, which engages with the rack F, and on the outer end of the shaft G ahand-wheel, K, or a crank-handle, or analogous device, is rigidly mounted, by means of which the shaft G and the pinion J can be turned 0r revolved. By revolving the pinion the die'block B will be moved laterally-that is, in the direction of the length of the rack and at right angles to the longitudinal axis of the striking-surface of the hammer L, held above the die, which hammer can be arranged to swing or reciprocate vertically. The dieblock can thus be shifted slightly after each stroke of the hammer, and thus the stock held in the die will be struck in a different place, if desired, at each stroke, and will be widened, flattened, or plated out, as is necessary in making wagon-clips, plates having stems, and like work.

If desired, the anti-friction rollers track-bars C can be dispensedwith.

The rack and pinion can be combined by suitable mechanism with the hammer, to shift the die-block automatically after each stroke of the hammer.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination, with the movable dieblock 13, of the rack F, secured on the same, the shaft G, the pinion J, mounted on the same, and engaging with the rack F, and of the hand-wheel K on the outer end of the shaft, substantiallyas herein shown and described. v

2. The combination, with the anvil I and D and the movable die-block B, of the rack'F, se-

curedon the die-block, the arm H on the an vil, the shaft G, held to turn in the arm H, the pinion J, mounted onthe shaft G and engaging with the rack, and of the hand-wheel K, mounted on the outer end of the shaft G. substantially as herein shown and described,

JAMES H. BAKER.
