DIE FOR MAKING CANT-HOOK CLASPS.

SPECIFICATION forming part of Letters Patent No. 706,691, dated August 12, 1902.

Application filed October 12, 1901. $erial No. 78,402. (No model.)

To (tZZ whom it may concern:

Be it known that'LOLE RUDD, a citizen of the United States, residing at West 'Duluth, in the county of St. Louis and State of Minnesota, have invented certain new'and useful Improvements in Dies for Making Cant-Hook Clasps and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its especial object to provide improved dies for forming cant-hook, clasps; and to this end it consists of the novel devices and combinations of devices hereinafter described, anddefined in the claim.

The invention is illnstratedinthe accompanyin g drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view, principally in front elevation, but with some parts sectioned, showing my improved dies and illustrating their action in forming the cant-hook clasps. Fig.

2 is a view, partly in side elevation and partly in section, on the line .50 m of Fig. 1. Fig. 3 is a section on the line :0 m of Fig. 1, the upper die being shown in full. Fig. 4 is a plan View of the lower and relatively fixed die. Fig. 5 is a bottom plan View of the two upper dies. Fig. 6 is a planview of the clasp completed except for final bending, and Fig. 7 shows the completed clasp in side elevation.

The construction of the cant-hook clasp which is to be formed will first be considered.

This clasp involves a thin split collar or sleeve l, at the ends of which are perforated ears or flanges 2, between which the cant-hook is adapted to be pivoted. To properly space these ears 2 and prevent the same from being clamped against the cant-hook, they are provided with cooperating spacing-lugs 3. My

improved dies are intended to properly form the ears 2 and lugs 3 at the ends of the split collar or sleeve 1. The intermediate body portion of the sleeve or clasp 1 may be prop erly reduced and drawn out in the ordinary way. s

The character a indicates the lower or relatively fixed anvil member of the dies, the

same having depressions a, which at their outer edges are rounded upward to form bending-shoulders a Each depression or pocket that is, each is adapted to form one end of the clasp.

For cooperation with each die pocket or recess a, is a vertically-movable die-block. I), which is provided with a depending plungersection b. The plunger-section b of each dieblock b closely fits the cooperating pocket or recess a, but in vertical length is much less than the depth of the pocket or recess a. At their outer edges the portions b are cut away or beveled on a curved line, as indicated at o for cooperation with the corresponding rounded bending-shouldercfi-of the die-block a.

The manner of forming the ends of the clamp is as follows: Before being presented to the dies the blank from'which' the clasp is formed has at both ends approximately the form indicated at the left-hand end of the blank shown in Fig. 1. While the ends of the blank are properly heated, so as to make them pliable, they are subjected one after the other or in any desired order to'the respective dies which are to properly form them. By the action of the dies theheaded end of the blank is reduced to proper form and size within the recess or pocket at, anda portion thereof is forced into the countersunk section a so as to form the spacing-lugs 3, as indi oated in Figs. 1 and 2. Also by the cooperating bending-shoulder a and beveled portion b of the movable die the body of the clasp,

adjacent to the ear 2, is bent and reduced, ap-

proximately, to the desired form or size.

The dies may of course be operated by the steam-hammer, drop-forge, or any other suitable device. It will also be understood that their use is not necessarily limited to forming so-called cant-hook clasps.

What I claim, and desire to secure by Letters Patent of the United States, is-as follows:

The combination with a die block or section having the rounded bending lug or shoulder a and an adjacent recess a with counterdie I) and bottoms of recesses a, a substansunk 1ug-forming seat a of the die-section b tially as described. IO having the depending plunger portion 6 fit In testimony whereof I affix my signature ting said recess a, and beveled or cut at b for in presence of two witnesses.

cooperating with the said rounded shoulder OLE RUDD.

apart said surfaces a 1) and the end of said T. TARALDSEN.
