HENRY M. BEECHER, OF PLANTSVILLE, CONNECTICUT.

Specification forming part of Letters Patent N 0. 123,079, dated J anuary. 30, 1872.

To all whom it may concern:

Be it known that I, HENRY M. BEEGHER, of Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Forging Carriage-Spring Clips, of which the following is a specification:

My invention consists of the improvement in forging carriage-spring clips by means of the dies herein shown and described.

In theaccompanying drawing, Figure l is a face view of the several die-blocks embodying my invention, and employed in the practice thereof. Fig. 2 is a vertical section on line a a; of Fig. 1, when arranged in proper position and closed; and Fig. 3 is a side elevation of the blank from which one style of clip is formed.

A designates the die-block, which forms the head or top of the clip, which die-block I prefer to arrange at the bottom, in the manner shown in the drawing, and secure it rigidly to the bed of the machine in which it is to be used. Upon the face of the die block A I form an elevation, at, the face of which is equal to the width, inside the head, of the clip designed to be forged by said dies. The sides of the elevation a are inclined at an angle of about forty-five degrees to its face. B designates Y the central die-block, which is of the same width as the face of the elevation at, and has vertical sides. In case the block A is rigidly secured, as suggested, the block B will be arranged so as to be raised and lowered by a drop or press. C C are the side die-blocks with vertical sides, and their lower inside corners inclined to match the inclined sides of the elevation at, so that the several blocks will all fit together, as shown in Fig. 2. In the face of the blocks A and C C I form one or more dies or grooves b b, of any form that may be desired, to form the body of the clip. Two different forms are shown in the drawing. If it is desired to form a groove in the under side of the clips head I form a bead or beads, c c, on the face of the block B, but this bead may be omitted. The respective die-blocks may be arranged in any suitable machine which is capable of giving the side dieblocks a lateral or swinging motion, and the block B or A a vertical motion. I usethese dies in the machine for forming carriage-shackles patented to myself June 20, 1871.

The operation of these dies is as follows: The block B is elevated above the other diebloclrs, and'the side die-block C C swung or thrown open, as indicated by broken lines in Fig. 2. For a clip formed of half-round iron and formed by the die I), the blank consists of a simple straight piece of such iron; but for a clip the body of which is triangular in form,

like the die b, I previously form the blank D, as shown in 'Fig. 3. After bringing a blank to a proper heat it is placed over die-blocks O A C, and the die-block B forced down upon it, and the side die-blocks forced toward the block B, as shown in Fig. 2. When the body of the clip is formed I force the blocks B and C C simultaneously upon the block A.

It will be noticed that the inclined sides of the elevation at are at the miter corner of the clip formed therein, and that the blocks open and close at said point in forging each clip; therefore a portion of the surplus metal or the fin, as it is called, will be thrown out at said corners-that is, at the point upon which the inclined or mitered portions of the blocks 0 C and A meet each otherand thus always insure a full corner.

I claim as my invention The improvement in forming carriage-spring clips by means of the die-block or plunger B and die-blocks A C C, provided with dies 11 or b, which open and close upon the lines, substantially as specified, whereby a fin is thrown out at or near the outside miter corners of the clip formed therein, substantially as and for the purpose set forth.

HENRY M. BEECHER.
