' SAFETY-CATCH.

Specification of Letters Patent.

Application filed May 14, 1920. Serial No. 381.268.

To all whom it may concern:

Be it known that I, LOUIS A. PAGE, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.v

This invention relates to improvements in so-called safety catches for pins such as cuff pins, beauty pins and the like; and has for its object to provide simple and effective means for closing the catch and preventing the point of the pin stem from being inadvertently removed therefrom.

The nature and advantages of the invention will be better understood when the following detail description is taken in connection with the accompanying drawings, the invention residing in the combination and arrangement of parts as claimed.

In the drawings forming part of this specification, like numerals of reference indicate similar parts in the several views and wherein Figure 1 is a side elevation of a pin-body, illustrating my improved catch as retaining the pointed end of a pin-stem.

Fig. 2 is a plan View showing the double hook-shaped arms as struck from sheet stock.

Fig. 3 is an elevation showing these arms as bent up forming a single central hookshaped body-member.

F ig. 1 is a front edge view of the hookshaped central body member, showing the side arms as bent up with their inner faces abutting each other.

Fig. 5 is a plan View showing the two gateforming arms struck from sheet stock.

Fig. 6 is a rear view of the body portion, showing the gate-member as straddling the same.

Fig. 7 is a side elevation of the body portion, showing the gate hinged thereto and in closed position.

Fig. 8 is the same as Fig. 7 but showing the gate as moved to open position.

Fig. 9 is a perspective view of the gatemember showing the swinging end of the two arms as connected together by a crossbar.

With reference to the drawings, 10 illus trates the base or body of a pin to which the usual pin-stem 11 is pivoted in the joint member 12, the opposite end of the pinstem being retained in my improved safety catch member 13. v The body portion of this catch member is preferably struck fromsheet stock first into the form illustrated in Fig. 2, providing two hook-shaped arms or wings 14 which are folded inwardly toward each other on the center line 15 between them, forming a central hook-shaped-body portion having an open mouth 16 for the reception of the pointed end of the pinstem 11.

The outer walls of this central body member are reduced in thickness or recessed as at 17, the depth of each recess being subarms 20' which are folded upward towardeach other on the lines 21, as shown in Fi 5, leaving the arms spaced apart to stradd e the recessed portion 17 of the body member, these two arms being connected together at their swinging end by'a cross-bar 22.

The outer ends of these arms are provided with a pivot hole 23 through which a pin 24 is passed through the eye 18 of the body member thereby attaching this gatemember to the body. A projection 25 is formed on the edge of each of these arms, which may be engaged by the thumbnail for readily swinging this gate either to closed or opened position on its pivot pin 21.

The cross-bar 22 serves to limit the outer swinging motion by bringing up against the inner edge of the body portion. In order to hold the gate in open position I have provided a slight protuberance 26 on the inner face of each arm of the gate, which will frictionally engage the body in swinging past it. This protuberance also serves to lock the gate in closed position as illustrated in Fig. 7, to prevent accidental opening thereof.

The base portion 27 of this body member may be secured in any suitable way to the body of the pin.

My improved safety catch is simple, prac- Patented Aug. 3, 1920.

tical and inexpensive in construction and by its use the pin-stem is securely retained in the catch against accidental removal therefrom.

The description is directed solely toward the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims I claim 1. A safety catch comprising two integral" hook-shaped arms folded closely together to form a central body member, a gate member in said recessed portion to either close or open the mouth of saidhook. I

3'. A safety catch comprising two hookshaped arms folded closely together to form a hook-shaped central body member, a gate member having a pair of arms straddling said body and pivoted thereto to' swing and close the mouth of said hook, and a cross bar connecting the swinging, ends of said arms arranged to engage the body portion and limit their opening swinging motion.

L A safety catch comprising two hookshaped arms folded closely together to form a hook-shaped central body member, a recessed portion on opposite sides of-said hook body, a gate member having a pair ofarms straddling said body and pivoted to swing in said recessed portion' to either close or open the mouth of said hook, and a detent for retainingsaid gateeither in-open or closed position.

In testimony whereof- I aflix my signature.
