IMPROVEMENT IN DIES FOR FORGING HAMMERS.
Specification forming part of Letters Patent No. 186,590., dated January 23, 1877; application filed January 5, 1877.
and useful Improvement in Dies for Forging Hammers, of which the following is a specification, reference being bad to the accompanying drawing, making part of this specification, in
Figure l is a perspective view of the two dies separated. Fig. 2 is a front view of the same closed on the blank. Fig. 3 is a vertical section at 3 3, Fig. 2. Fig. 4 is a perspective viewof the blank as it appears before the ac- Fig. 5 is a perspective View of the blank as it appears after the action of the dies. a
In forging the eye of an adz-eye hammer by the processes described in my application filed 23d of November, 1876, it becomes necessary or advisable to contract the blank somewhat at the point b 12 where the adz-eye is to be formed, previous to the final drawing down of the same, as therein described; also,
. after the preliminary punching of the taper hole, as therein described, it becomes necessary to correct the bulging thereby created by exposing the bar flatwise to the action of flat dies. 'To effect both objects at one and the same motion of the press the rises or projections B B on the dies A A have beendevised. G is the gage, (usually made adjustable,) against which the side of bar is laid, the preliminary taper hole therein being tilled with a mandrel, H, with a fleam-shaped or taper point. So much of the bar'as is exposed to the action of the flat surfaces of dies A A described, with projections B B for thinning the blank at b 12 in the act of pressing the bar flatwise to correct the bulging produced in the punching of the preliminary taper hole.
