To all whom it may concern:

Be it known that 1, CHARLES J; LEYERS, a States, residing at East Rutherford, county of B rgen, and State of New Jersey, have inven i certain new and useful Improvements in Apparatus for Making \Vire-C-ore Hair-Pins, of

which the following is a full, clear, and concise description.

This invention relates to the manufacture of hair-pins, and more particularly to the construction of hair-pins of plastic material reinforced by a central longitudinal core of wire embeddedyor formed into the same, whereby the article "is strengthened against fracture and is capable of various useful manipulations, the object of the invention being more especially to produce a hair-pin of celluloid in imitation of tortoise-shell or amber which may be readily bent into any desired shape without danger of cracking or breaking .or other deterioration.

block being supported Referring to the accompanying two sheets of drawings, which form a part of this specification, Figure 1 is a view in perspective of" an apparatus for making the article. Figs. 2, 3, and 4 are transverse vertical sections on the line a a of Fig. 1, showing said apparatus in successive stages of operation upon a blank. Fig. 5 is a detail and modification of the frame and forming-dies, and Figs. 6 and 7 are respectively the article straight and bent.

The apparatus comprises a lower block 1, which is preferably mounted, as a laten, upon a fixed support, and an upper b ock 2, which may be moved toward the lower block by any suitable mechanism, such as a system evers operated by a oot-treadle, the said y a central pillar guided in the framework to permit of such movement. The lower block or platen 1 is provided at its opposite ends, respectively, with a headed stud 3, and the frame containing the forming-dies is adapted to be inserted upon the block under the heads of said studs, as shown in FigL-l. The said frame comprises two end'pieces 4, united by a pair of'spring-straps 5 and 6, and the forming dies are disposed between the end pieces and under the straps, being'permanently united to the latter by screws or rivets 7 at substantiall their central points. i

ll;- e forming-dies are identicalin shape an flat'end faces in contact with the flat'sides of the end pieces 4 4, as shown in Fig. 1, or they determined 'yond the endedge of the heads of the studs as the frame is construction and may be provided with may be providedwith a suitable dovetail or tenon 8, engaging m a corresponding channel or mortise in the sides of the end pieces,

(indicated in Figs; 1 and 5,) but permit them to approach and come into operative e'ngagement with each other, as shown in Fig. 4, the resiliency of the-straps being sufiicient to retract the dies to their normal open positionwhen the closing force has been removed. The proper position of the forming-frame under the heads of the studs 3 3 is gaged and by means of the end portions 9 of which are extended over and bepieces 4 and strike against the the strap 6,


The upper or cam block 2 is recessed or channeled longitudinally on its under-surface to receive the creaser-bar 10, which latter is preferably of slightly less length than lthe dieblocks and is supported by two vertical posts 11, extending upwardly therefrom through the roof of the recess and normally pressed in an upward direction by means of the spiral springs 12, interposed between the heads of the posts and suitable brackets secured-to the block. The postsll are each provided with transverse notches adapted to be engaged by the spring-catches 13 for holding them, and consequently the creaser-bar, in a depressed posltion, protruding somewhat beyond the opening of the recess, the springcatches 13 being provided with convenient thumb-pieces overlapping the end of .the upper block. The tapered pins 15 at the four corners of the block 2 are adapted to enter. the recesses 16 in the lower block a greater or less extent and upon a sufficient relative movement of the two parts are adapted to engage the backs of the forming-dies and cam or wedge them together. In operation the two blocks 1 and 2 are first separated, and a strip of celluloid previousl cut of the pro er size and of uniform thickn ssfor the wor in hand is placed upon hexrawe mid 15 thus rim-a1 the top of Lhe forming-dies iwiax'wii spring-straps above mun mmi, the in normal opcn position, 501 Fm (mv What I proper placing 0f the imp.
