SAFETY CATCH Filed July 17, 1954 Patented June 11, 1935 UNITED" STATES SAFETY CATCH Clarence S. Oakey, Oriskany, N. Y., assignor of one-half to Samuel McL. Birch, Clinton, N. Y.

Application July 17, 1934, Serial No. 735,641

4 Claims.

My invention relates to a safety catch and I declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing in which like reference characters refer to like parts throughout the specification.

The object of the invention relates to a device that is applied to broaches, fraternity andother similar pins, or necklaces, whereby to lock the pin stem within its post and thereby prevent the accidental displacement of said stem with the consequent loss of the broach or other pin.

Furthermore, the'catch is simple in construction. It is made removable, whereby it can be easily replaced when worn or at the will of the user.

The object will be understood by referring to the drawing in which:

Fig. 1 is a perspective view of the device shown applied to a broach.

Fig. 2 is a detailed view showing a perspective of the locking device.

Fig. 3 is a detailed view showing a perspective of the safety keeper.

Fig. 4 is a detailed view showing a perspective of the post or employed member.

Fig. 5 is a detailed View showing a perspective of the safety keeper with the members spread apart to expose the interior.

Referring more particularly to the drawing, the device embodies a post I which is soldered to the broach 2 at 3. Post I is made in the form of a hook having its free end 4 open for the reception of stem 5 of broach 2 when the broach is Worn.

There is a rotatable keeper member I2 cooperating with post member I, whereby to effect a lock. Laterally extending annular bosses I3, I3 are formed integral with the inner surface of the rotatablekeeper member I2, whereby to hold said keeper I 2 in rocking relation to the free or upper end 4 of post I. To'this end annular bosses I3, I3 fit into the annular opening 6 of end 4 of post I which forms a bearing for said bosses and holds said keeper I2 in place with relation thereto.

Keeper member I2 is made with two duplicate parts l4 and I5 that are joined together by a part I6 and then bent to be in parallel relation to each other, part I6 forming in this latter instance a U shaped member. Parts I4 and I5 are circular and each has a central open aperture I'I- formed therein for the projection of stem 5 therethrough. Part I4 of keeper I2 is shorter than part I5. Its free end is bent inward at I8, to engage complementary notches I9 and 20 formed in the free end 4 of post I, whereby to hold keeper I2 in either open or closed position.

The upper edge of joining part I6 is enlarged at 29 to provide a finger catch to aid in rotating keeper I2. Keeper I2 is mounted upon post I by pressing it into place thereon. Parts I4 and I5 will yield sufficiently to allow bosses I3, I3 to snap into the bearing part 6a of post I. It can be removed likewise by pulling it from its assembled position. 5

In operation the user presses stem 5 through the cloth of his or her coat or dress and engages the free end 24 of stem 5 into the open free end 4 of post I. Keeper member I 2 is then rotated from dotted line position illustrated in Fig. 1 to full line position, whereupon end I8 of its member I4 will engage in notch 20 to hold said keeper I2 in locked position. End I8 will ride in and out of notches I9 and 20 when said member I2 is rocked the proper degree by hand.

It will be observed that keeper I2 can be mount ed to post I after said post I has been soldered or otherwise secured to broach 2.

Heretofore, some difficulty has been experi enced in mounting safety catches where the keeper I2 and post I are joined and then post I soldered tov broach 2. In this instance, the solder flows down and interferes with the working of keeper I2, whereas in the present invention, post I is mounted to broach 2 I2 mounted on post 2 afterwards by hand.

Having thus described my invention whatI claim as new and desire to secure by Letters Patent is as follows: v

1. In a safety catch, a post member having an open aperture therein, a rock member mounted on said post member, said rock member formed with duplicate parts having laterally extending shoulders that fit within the open aperture of said first named member, whereby to form a bearing and means for holding said members in given relation to each other.

2. In a safety catch, a post member having an open aperture therein, a rock member mounted on said post member, said rock member having parts with open apertures formed therein, lateral- 1y extending lugs formed on said r-ock member, whereby to fit within the aperture of said post member to form a bearing and means for holding said rock member in predetermined relation with said post member.

3. In a safety catch, a post member mounted on a broach, a rock member mounted on said post member, recesses formed on said post memby soldering and keeper her, and a yielding end on said rock member for engaging the recesses formed on said post member, whereby to hold said rock member in an open or closed position with relation to said post member.

4. In a safety catch, a post member having an open'aperture therein, a, rock member formed with duplicate parts and having open apertures in said duplicate parts being bent to engage said post member, said rock member being mounted on said post member and a third part joining said duplicate parts of the rock member to aid in rotating the same with respect to said post member, whereby to open and close the aperture in said post member.
