Letters Patent No. 93,951, dated August 24,1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come: k

Be it known that I, HENRY M. BEECHER, of I Plantsville, of thevcounty of Hartford, and State of Connecticut, have 'made a new and useful invention,

having reference to Dies for the Formation of Car-` riage-Shaft Connections or Shackles; and do hereby declare the same to be fully described in the following 1 specificatiom and represented in the accompanying drawings, of whieh- Figure l is a front-end view,

Figure 2, a bottom view, and

Figure 3, a top view of a shaftfshackle blank, as it is swaged out preparatory to having its arms bent up, with respect to the shank, in manner and by mechanism as hereinbefore'desclibed.

Figure 4 is a top view,

Figure 5, a side'elevation, and

Figure 6, a frontend view of the shaft-shackle blank, as bent and formed by the said mechanism.

Figure 7 is a top view,

Figure 8, a transverse section, and

Figure 9, a longitudinal section of the lower or stationary die, employed in effecting the bending `and formingof the blank. Y

lFigure l0 is an under-side View,

Figure l1, a side View, and

Figure l2, an end View Of the dropdie. y The object of the stationary and drop-dies to be hereinafter desclibed, is to impart to the article, or shackle-blank, as exhibited by figs. l1, 2, and 3, the form of that shown in figs. 4,' 5, and 6. In these latter figures it will be observed that the arms a a of the cross, shown in figs. 1, 2, and 3, have been bent up into, or, about into. parallelism with each other, and so as to stand at right angles, or thereabout, to therhottom of the shank b, the vertices of the angles of the shank, and arms being completed.

It will be seen` that the arms are pressed' down, so as to project at equal distances from the shank.

The blank, shown in figs. 1, 2, and 3, is rst swaged with projections o c, which, when the arms are bentA as described, serve to filloutandcomplete theup blank at and near the vertices of the arms andshank.

The plate of thelower or stationary die is shown at A, as' provided with a semi-cylindrical recess or die, d, which,with another such recess or die fl, formed in the drop-die B, serves to complete the round part or head e ofthe cross.

angles of the This plate A may be in one piece with the bedblock C, or it may be separate therefrom, and be slid into a groove or channel, f, made through it.

VAnn-dies!! g are arranged on opposite sides of the channel f,and extend up from the plate A, in manner as represented.

They co-Operatewith the palt '71 and two semicircular arches or'upsetting-ydies, i fi, formed in the drop-die B, in manner as represented. v Leading upward from the arm-dies, and (formed in manner-as .shown) in posts k k, erected On the bedblock, are two recesses or bending-guides l Z, curved and otherwise formed, as shown in the drawings.

There is, a -hollow or die n, in the bottom of the drop-die, such being to operate with the flat surface 11, of the plate A, in giving form to the shank b of the shaft-shackle, as shown in gs. 4, 5, and 6.

In using the dies, the blank is to be so laid on. the lower one, with the arms resting in the bending-guides, after which the drop-die is to be forced down upon the blank, so as to crowld it down into-thebed-block, and the aim and head-dies thereof, so as to-cause the arms to bend up into right angles with the. shank and enter the upsetting-dies, and be crowded'down to a level with each otberby them.

I claim as my invention, in the above-described mechanism, the following, Viz:

The combination and arrangement of the bendingguides l l, and the arm-dies g g, with the' bed-plate A and the drop-die B.

Also, the combination and arrangement of the upsetting-dies i. i, with the drop-die B, and with the arm-dies g g, bending-guides l Z, and die-plate A of the bed-block.

Also, the combination of the head-dies d il', with the die-plate A, thel drop-die B, the arm-dies g g, the bending-guides l l, and the upsetting-dies t i.

Also, the combination and arrangement of the' shankfdies n p, the head-dies d d', thel arm-dies g g, the upsetting-dies 'l t, and the bending-guides Z l, the whole being applied'to the bed-block and the dropdie substantially in manner and so as to operate as and for the purpose Or purposes hercinbefore specified.

HENRY M. BEECHER.
