IMPROVEMENT IN DIES FOR FORGING CARRIAGE STAY-ENDS- Specifi cation forming part of Letters Patent No. 176,718, dated April 25, 1876; application filed April 6, 1876.

To all whom it may concern Be it known that I, WILLIAM S. WARD, of

-Plantsville, in the countyof Hartford and State of Connecticut, have invented a new Improvement in Dies for Forging Carriage Stay-Ends; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and

" exact description, andwhich said drawings constitute part of this specification, and represent in'- Figure 1, ,face view of one part; Fig. 2, face view of the other part of the die; Fig. 3, a section on line a .70 of Fig. 1; Fig. 4, a transverse section of 'the'same, Fig. 4:, a transverse section on line 22; Fig. 5, perspective view of the stay-end; and in Fig. 6,"a transverse section of the plate, as formed by the usual construction.

This invention relates to the construction of dies for forging what are termed carriage stay-ends,th'at is to say, the foot or plate whichis attached to the side of the perch and a portion of the brace which forms the stay, such as seen in Fig. 5, a. being the plate and b a portion of the brace.

.In this condition the article is furnished to the trade, and the smith welds to thebrace to give it the required length.

In the usual construction of the dies fornaking this article, the dies are divided in a central plane through the plate and brace. This necessarily makes the fin at the center of the plane side of the plate, as seenin Fig. 6, and in order that the (lies may separate after striking the piece, it is necessary to make that plane surface slightly inclined irom the center outward, as seen in Fig. 6, some-' what magnified, which requires that that surface of the plate shall, be filed or dressed fiat, or that the wood be cut so that the plate will fit.

seen in Figs. 3 and'4.

The object of the invention is to overcome this diificulty; and it consists in the dies as hereinafter described and as shown in the accompanying illustration.

The lower part Fig. 1 has a plane surface,

A, in .this a cavity, c, is formed, corresponding to the plate a, and from thisa branch cavity, d, corresponding to the shape of the brace. The brace, as here represented,- is made octagonal at its junction with the plate, and this cavity 01, in transverse section, corresponds to five of the eight sides, as seen in Fig. 4, hence a little more than half of the brace and plate will lie below the plane A. In rear of the cavity 0 the die is raised, as at B, so as to make the back of the cavity 0 correspond to the entire surface of the plate a, as

, In the second part of the die the surface D D corresponds-to the plane A A of the first part, and a cavity, E, is formed corresponding to the raised portion B, and a branch cavity, d, corresponds to. the cavity 01, and in form for the completion of the brace. V

By this construction, the fin on the plate a, which is formed from the surplus metal, will be forced between the two parts of the die and at the upper edge of the plate, and from there may be easily removed bythe usual clipping 7 dies, and the surface of the plate will be per fectly fiat, Without the 'usually required fin-
