MACHINE FOR FORMING CAR-FOLLOWERS.

SPECIFICATION forming part of Letters Patent No. 320,502, dated June 23, 1885.

Application filed April 2-2, 1885. (No model.)

To all whom it may concern.-

Be it known that I, HENRY RHYN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Machine for Forging Gar-Followers, of which the following it a specification.

This invention relates to the class of machines which are used to form and punch followers with theaid of the steam-hammer, and of which the following is a description, which is as full and clear as I am able to give, reference being had to the drawings hereto annexed, ot'which- Fig. 1 is a perspective view of the entire machine; Fig. 2, a sectional view of the blocks A and B and pin-punch O and iron H.

I-Ierctofore followers have been first formed with one device and then punched with another. Thus in using two devices it requires two operations. \Vith my new machine the forming and punching is done in one operation. This I accomplish with only three parts, viz., one upper block, A, lower block '13. and pin-punch O.

pin-punch O is larger at the punching end a,

so that when this large end is driven through the iron H by blows of the steam-hammer it will readily fall out of the iron and through the block B.

The thickness of the blocks A and B and the depth of the flanges a a, also the length of the pin-punch 0, depends upon the thickness of the follower to be forged.

It will be seen that if the blocks are made proper size, the block B is placed upon the anvil K of the steanrhammer, when the iron is laid upon said block and the block A upon the iron H in such a way that it will match the block B. Then the pinpunch O is inserted into the hole of block A, and by blows upon the top w of the machine a follower is formed and punched.

In order to facilitate the handling of the blocks, so as to have them always ready for operation, I fix a springhandle, G, to the projections a and b, with two set screws, g g. Said handle is bent at q, as shown.

To maintain the blocks in a true position to each other, a stud, E, is fixed into the pro jection b of block B, which stud extends into a hole in the projection a of block A. Said stud E serves also in holding a spiral spring, F, in position.

As the flanges of the upper block press against the ends of the follower in the operation, two straps, D D, are placed over the iron H, and the ends of said straps fastened to the sides of block B, when the spring F releases the flanges of the upper block from the follower.

To prevent injury to the straps, I form 1 grooves a a into the under face of the upper block, by which means all the extra force of the blows of the hammer is brought upon the whole face of the follower.

The edges of the flanges a a of block A and straps D D are of a proper and even distance from the upper face of block B, so that the iron will pass through freely.

After the iron is forged to its proper size, it is inserted between the blocks, and the pinpunch placed in the hole of the upperblock, as shown in Fig. 1, and by one or more blows of the hammer on the top a; of the machine the flanges and pin-punch are driven through the iron, as is seen in Fig. 2, when the machine is partially removed off the anvil K, so as to allow the punchings h and pinpunch G to fall out, and, by inserting the iron for'the next operation, the finished follower in the machine is easily removed.

I am aware that the pin-punch 0 could be screwed into or fastened otherwise to the block A at its place of the hole; but I prefer to use the pin-punch independent and disconnected of the blocks A and B, as, by reason, a tapering hole, 7), projection b, straps D D,

the pin-punch being larger at its end 0, it and the block A, having a straight hole,

will be free of any pressure from the follower, grooves a a, flanges a a, projection a, and

and said follower is correspondingly easier pin-punch 0, formed with punching end e. 15 5 released from the block A, having the flanges. with spring-handle Gr, stud E, and spiral I elaimspring F, all as drseribed, and for the purpose 1. The combination of the blocks A and B, set forth. having holes and pin-punch O, the block A, HENRY RHYN. having flanges a a serving as cutting-edges, \Vitnesses: 10 substantially as set forth.

2. The combination of the block B, having NELSON \VASS.
