SPECIFICATION forming part of Letters Patent No. 743,835, dated November 10, 1903.

Application filed July 16, 1903. Serial No. 165,719. (No model.)

To 00% whom it may concern:

Be it known that I, CHARLES JOSEPH DIEGES, a citizen of the United States,residin g in the city, county, and State of New York, have invented certain new and useful Improvements in Automatic Catches for Badge- Pins, &c., of which the following isa specification sufficient to enable others .skilled in the art to which the invention appertains to make and use the same.

The object of my invention is to afford a positive automatic catch for brooch, badge, and other similar pins used to secure such articles in place; and it consists, essentially, in the special construction and arrangement of parts hereinafter described and claimed specifically.

In the accompanying drawings, Figure 1 is a view of the back of a plate to which my improved pin catch is applied; Fig. 2, an edge view of the plate. Fig. 3 is an end view of the plate, showing the pin secured. Fig. 4 is a transverse section upon plane of line 4 4, Fig. 1, showing the catch-lever and spring in elevation and the pin locked in position. Fig. 5 is a view similar to Fig. 4, showing the catch-lever depressed and the pin released. Fig. 6 is a view of the blank from which the socket-piece is formed. Figs. 7 and 8 are respectively views showing opposite edges of the socket-piece. Fig. 9 is a view of the under side of the plate and socket-piece with the catch removed. I

B represents the backing or plate of abrooeh, badge, or other similar article, to which is pivoted the usual pin P, formed with the toe p, which rests against the under side of the plate B when the pin is pressed 'inward,so

' that the elasticity of the metal of which the or otherwise rigidly secured to the back of theplate-B. Thus, as shown in Fig. 6 of the drawings herein, a blank S may be stamped 0 at with the curved central projection s, cheekpieces 3 .9, slot 3 and tongue 8 the central projection when the blank is folded constithe other figures, while the edge 5 of the slot 5 becomes the fulcrum upon which the catchlever C articulates. The tongue 3 being folded over at the rear of the socket-piece S,serves to retain the 'locking-sprin g L, which is thus held loosely in the lower part of the socketpiece below the catch-lever O, which it tends constantly to maintain in its normal position, as shown in Figs. 4: and 5.

The catch lever G is formed with a notch c at or near its lower extremity, the edge of which notch engages with the fulcrum edge 5 of the socket-piece S. The catch-lever is also formed with the locking-h 00k 0' and finger-bearing 0 The upper surface 0" of the hook c is curved or inclined for the purpose of facilitating the depression of the catchlever 0 when the pin P is forced down upon it.

The operation will be readily understood. The depression of the catch-lever against the resistance of the spring L by pressure applied to the pin P not only throws back the hook 0, but also bends the pin by reason of the engagement of its toe p with the rear side of the plate 13. W'hen the pin P is depressed below the point of the hook c, the latter is forced upward and forward by the lockingspring L securing the pin against the guide 3.

WVhen it is desired to release the pin P, the

catch-lever O is depressed by means of the finger-bearing 0 As soon as the point of the hook c clears the pin P, the latter owing to its resilience springs outward clear of the catch, and upon the release of the finger-bearing 0 the locking-spring throws the catchlever 0 back into its normal position. It is thus apparent that the articulation of the catch-lever is effected with the least possible latter feature is of especial importance in the case of very small catches in which the parts are necessarily minute and delicate, it being understood that the accompanying drawings show the device upon an enlarged scale and that in practice it is frequently necessary to make the Whole catch of no greater dimensions than one-eighth of an inch in any direction. Hence the elimination of the pivot is of practical importance in a commercial sense, since the initial cost of manufacture is not only reduced, but all danger of the catch being rendered inoperative and useless by reason of the looseness or loss of the pivot is avoided, as well as the tightness and stiffness in action which are apt to arise between the parts by the binding action of the pivot. In my device the catch-lever and its spring rest loosely between the inner side walls of the socket-piece and have but slight frictional contact therewith.

What I claim as my invention, and desire to secure by Letters Patent, is i 1. The combination with the plate and the pin pivotally connected thereto, of a socketpiece integral with said plate and formed with a fulcrum edge, a catch-lever supported in said socket-piece and formed with a notched bearing for engagement with the said fulcrum edge, and a spring in said socket-piece arranged to hold said catch-lever in its normal position, substantially as set forth. 7 2. The combination with the plate and the pin pivotally connected thereto, of a socketpiece integral with said plate and formed with knife-edge fulcrum, a catch-lever supported in said socket-piece and formed with a notched bearing for engagement with said knife-edge fulcrum, and a spring in said socket-piece arranged to hold said catch-lever in its normal position, for the purpose described.

3. The combination with the plate and the pin pivotally connected therewith of a socketpiece made of a single piece of sheet metal cut and bent into the desired shape and secured rigidly to the said plate, a catch-lever engaging with a fulcrum edge formed on said socket-piece, and a spring in said socket-piece arranged to hold said catch-lever in its normal position for the purpose set forth.

4. The combination with the plate B, and the pin P, pivotally connected therewith, of the socket-piece 0, formed with the fulcrum edge .3, the catch-lever 0, formed with the notch c, for engaging with said fulcrum edge 8 and the locking-spring L, for the purpose described.

5. The combination with the plate B, and the pin P, pivotally connected therewith, of the socket-piece 0, formed with the fulcrum edge 3 and guide 8, the catch-lever G,formed with the notch c, hook c, and finger-bearing c and the locking-spring L, for the purpose set forth.
