DIE FOR FORGING CARRlAGE-SHACKLE BLANKS.

SPECIFICATION forming part of Letters Patent No. 325,073, dated August 25, 1885.

Application filed July 18, 1854.

T0 aZZ whom it may concern:

Be it known that I, PETER GILLICK, of Southington, in the county of Hartford and State of Connecticut, have invented a new 5 Improvement in Dies for Forging Carriage- Shackle Blanks; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a perspective view; Fig. 2, a perspective view showing the under face of the 1 upper die; Fig. 3, aperspective view showing the upper face of the lower die; Fig. 4, a perspective view of the blank.

This invention relates to an improvement in dies for forging blanks for CZtITlilgGSllfiCklGS.

The blank to be produced is seen in perspective, Fig. 4, and is the usual form for these blanks, and which blanks are bent in dies constructed expressly for the purpose,to turn the ears A A up at right angles to the plane 2 of the body B. Such bending-dies are common and well known, and constitute no part of my invention.

The object of my invention is to form this blank from a single piece of metal and by two operations only; and it consists in the construction of the (lies, as more fully hereinafter described.

The dies consist of two parts or blocks, 0 D, 0 representing the upper and D the lower part of the die, these two parts being arranged in drop-presses in the usual manner of arranging forging-dies.

in one end of the two parts is a cavity corresponding in outline substantially to the out line of the blank to be produced. One half of this recess, E, is in the upper and the other (No model.)

half, F, in the lower part, the division being in a longitudinal central line through the ear portion, and so that the recess has the form of the blank standing in a vertical position. This recess is open at the end, as seen in Fig. 1, and constitutes whatI term the break-down die.

The bar or piece of metal from which the blank is to be formed is introduced between the two parts E F of the cavity when the parts 50 of the die are separated, and then as the dies come together they strike the blank and bring it to an outline of the cavity E F.

Upon the upper face of the lower part, D, I form a cavity, G, in outline and depth corresponding to the shape of the completed blank, as seen in Fig. 4. The corresponding or under face of the part 0 is flat.

The partially-formed blank as it comes from the cavity E F is laid into the cavity G in a horizontal plane. Then the part 0, struck thereon, will bring the blank to the shape of the cavity G, and as seen in Fig. 4. If in this last operation there be a fin left around the blank, that will be trimmed in the usual manner.

While I prefer to make each part of the block in a single piece, the open cavity E F may be formed in blocks separate from the block having the cavity G in its horizontal face.

I claim- The herein-described die for forging carriage-shackle blanks, consisting of the two parts, each constructed with like cavities, E F, in a vertical plane, the cavity open at one 75 end and one part with a cavity, G, on its horizontal face, the corresponding face of the other part flat, substantially as described.

PETER GILLICK.
