Description
UNITED STATES PATENT CFFIGE.'
HENRY HARRISON WARREN, OF BRIDGEWATER, CANADA.
IMPROVEMENT IN DIES FOR FORMING HAMMER-EYES.
Specification forming part of Letters 'Patent No. 146,217, dated January 6, 1874; application filed Novcnib`r 8, 1873.
To all whom it may concern:
Be it known that I, HENRY' H. WARREN, of Bridgewater, in the Province of Ontario and Dominion of Canada, have invented a new and useful Improvement in Dies for Forming Hammer-Eyes, of which the following is a specification The object of this invention is to furnish an improved vmeans for forming the eyes of nail and other hammers, of the shape and style of the adz-eye; and it consists in constructing the dies with recesses or formingsurfaces which will give the eye of the hammer-blank the preliminary form necessary to the proper action of a punch or plunger employed to fmish the eye.
In the drawing, Figure 1 is a perspective view` of the upper and lower dies connected, as when in use. Fi g.--2 is a vertical cross-section of Fig. 1. Fig. 3 is a vertical longitudinal section of the same. Figs. 4, 5, and 6 show the form of the eye during the different stages ot' the process. Figs. 7, 8, and 9 are perspective views, showing the hammer-blank as it passes from one stage to another in the process of forming the eye.
Similar letters of reference indicate corresponding parts.
A is the bed-die; B, the upper or movable die. The former is provided with grooves C, to adapt it for attachment to a power-press, and has a socket or recess, E, to receive the punch or plunger F of the upper die. D is a groove for holding the hammer-blank in posi- I B. By these supplementary die-surfaces, the
eye of the first hammer-blank, Fig. 7, is crushed and shaped both endwise and sidewise, to bring it to the form shown in Figs. 5 and S. The action of the punch F is subsequent to this shaping process, and reduces the blank to the form shown in Fig. 9. I
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The' dies A B, as described, having cavities or recesses I and J therein, as and for the purposes described.
HENRY HARRISON VARREN. Witnesses:
E. C. FLINT, J. L. STAMFORD.
