MANUFACTURE OF LACING=STUDS.

SPECIFICATION forming part of Letters Patent No. 415,297, dated November 19, 1889.

Application filed March 18, 1839. Serial No. 303,775. (No model.)

To all whom it may concern:

Be it known that I, IRA F. PECK, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented it new and useful Improvement in the Hanufacture of Lacing-Studs, of which the following is a specification.

IIeretofore lacing-studs provided with an attaching hollow shank have been made, either from sheet metal, or from a solid rod of suitable size, which rod was turned down and drilled to form the required hollow shank. The lacing-studs, when formed of sheet metal, are comparatively weak and do not present the required regular outline and solid appearance desired for many uses, and the operation for making the lacing-studs from a solid rod, though performed by means of automatic machinery, is a comparatively slow and expensive one; and it is the object of my invention to produce solid lacing-studs in a more rapid and economical manner than heretofore.

My invention consists in forming up the lacing-studs in suitable dies from pieces of solid wire of small diameter, as hereinafter fully set forth.

Figure 1 represents a side view of the cylindrical piece of solid wire from which the lacing-stud is to be made. Fig. 2 represents a side view of the blank after the first operation of the dies. Fig. 3 represents a side view of the blank after the second operation of the dies. Fig. 4 represents a side view of the blank after the third operation of the dies. Fig. 5 represents a side elevation, and

Fig. 6 a top view, of the lacing-stud completed at the fourth operation of the dies.

In the accompanying drawings, A represents a cylindrical piece of solid Wire cut off at the proper length to form the desired lacing-stud, having a hollow attaching-shank, and in carrying out my invention the Wire A is first placed in suitable dies, and one end portion a of the same pressed to form the flattened eccentric disk Z), Fig. 2, after which the disk I) is to be drawn up in suitable dies to cup form, as shown in Fig. 3, thus forming the eccentric cup c,which subsequently forms the attaching-shank B of the lacing-stud. Then the cup is to be upset, so as to form the annular flange d, and then the remaining portion a of the original blank A is to be upset to form the hook-head G, as shown in Figs. and (1.

Solid lacing-studs with hollow attachingshanks can be very rapidly and economically manufactured by the method described, the studs so made being of improved quality, and in their manufacture the comparatively slow and expensive process of drilling out the hollow of the attaching-shank, as heretofore, is avoided.

I claim as my invention- The described process of manufacturing lacing-studs, which consists in first upsetting one end of a solid wire blank to form a flattened eccentric disk, then drawing up the said disk to form an eccentric cup, then upsetting the cup to form a flange at its base, and then upsetting the remaining solid portion of the blank to form the head of the lacing-stud.
