PRQCESS OF MAKING SPLlT-SHANK CURTAIN-KNOBS.
SPECIFICATION forming part of Letters Patent No. 788,552, dated May 2, 1905.
Application filed May 31, 1904. Serial No. 210,495.
To all whom, it may concern.-
Be it known that I, FRED A. NEIDER, a citizen of the United States of America, and a resident of Augusta, county of Bracken, State of Kentucky, have invented certain new and useful Improvements in Processes of Making Split-Shank Curtain-Knobs, of which the following is a specification.
The object of. my invention is a means of making a split-shank curtain-knob in a few simple steps. This object is attained in the manner described in the specification and by the steps illustrated in the accompanyingdrawings, in which Figure 1 is an elevation of the blank after the first step. Fig. 2 is a similar view after the second step. Fig. 3 is an end view of the blank shown in Fig. 2. Fig. 4 is a view, partly in elevation and partly in section, showing the third step of the operation. Fig. 5 is a side elevation of the blank after the step has been taken. Fig. 6 is a view, partly in elevation and partly in section, of the completed knob. Fig. 7 is an inverted plan view of the collar. Fig. 8 is a plan view of the jaws for compressing the shank.
In the first step a head A is formed upon a metal rod, preferably of wrought metal, whose circumference is that of the neck a of the completed knob. In the second step a sliver of metal a is removed from the transverse diameter of the rod from theend up to the neck a. Then the end of the rod is compressed to form shank a" 11 leaving a shoulder a" between it and the neck a. The compression of the end of the rod to form the shank may be accomplished by forcing it into a bell-mouthed die B whose circumference is that of the shank of the knob and whose upper edges are beveled olf to render it bellmouthed in shape, or the compression may be made by means of two movable jaws C O, having semicircular grooves c 0 upon their meeting faces, and. which are beveled upon their upper edges similarly to the die B to form shoulder a. After the shank has been formed by compressing the lower end of the rod collar Dis forced over the end of the shank against the shoulder a to complete the knob. It is seen by this operation the operation of milling down the end of the rod to form the shank is obviated and that the operations are simpler than would be the operations in such a process wherein the shank would have to be milled down and split to form the knob of this character.
What I claim is- The process of making a split-shank curtain-knob which consists in forming a head upon a rod, cutting a sliver of metal out of the interior of and compressing the opposite end of the rod to form the shank.
