SAFETY-CATCH.

To all whom t may concern:

Be it known that I, SALOMON UNGER, a subject of the King of Austria, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Safety-Catches, of which the following is a specification.

My invention relates to improvements in safety catches, and more particularly to devices of this character adapted to be used in connection with breast pins, and the like, which will elastically hold the pin in the catch and prevent accidental movement.

A further object is to provide a device of this character in which the movable member comprises an angular pivoted guard which is provided with a spring tongue movable over a shoulder on the catch so as to hold the guard in either` its open or closed position.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In theV accompanying drawings: Figure 1 is a perspective view of a breast pin illustrating my improvements in connection therewith. Fig. 2 is a view in section on the line 2 2 of Fig. 4:. Fig. 3 is an end elevation of the device shown Vin Fig. 1. Fig. Ll is a view in section on the line M of Fig. 3. Fig. 5 is a perspective view of the catch, and Fig. 6 is a perspective view of the guard.

l represents a breast pin having a pin 2 connected thereto by a hinge 3. The pointed end of pin 2 is adapted to be positioned in a catch 4, and held against accidental displacement by means of my improved guard 5.

The catch 4 comprises a shank 16 having a hook shaped pin-receiving outer end 6, and at the juncture of said hook shaped outer end and the shank, the catch is formed with an integral rectangular enlargement 7 forming two iat faces 8 and 9 at right angles to each other and meeting at a rela-l tively sharp shoulder 10. The shank 16 isv provided with an opening l1 for the recep- Specication of Letters Patent.

tion of a rivet 12 to pivotally connect the guard to the catch. The guard is composed of spring metal of general U-shape in cross section with its side members preferably of somewhat triL ngular form as indicated and having openings 13 to receive the rivet l2 when projected through the opening 11 and pivotally connect the guard in place. The guard, at its angles, is split from its lower end upwardly the desired distance as indicated at 14 to form a spring tongue l5, and this spring tongue elastically bears against the flat surfaces 8 and 9 to hold the guard either in its closed o-r open position, and said tongue is caused to move outwardly when the guard is swung to either position by reason of the shoulder l0.

When the pin 2 is to be inserted' in the catch, the guard is swung down to a hori- Zontal position with its spring tongue 15 engaging the flat surface 9. When the pin 2 is in place, an upward movement of the guard will cause the spring tongue 15 to ride over the shoulder 10, and will then elastically bear against the flat surface 8 and hold the guard in closed position. It will thus be noted that with my improvements, it will be impossible for the guard to accidentally open, but when opened, will remain in such a position so as not to interfere with the entrance of the pin and the catch. These are features of importance, and as such features are embodied in a construction which is of eXtreme simplicity, they produce vastly improved results.

Various slight changes might be made in the general form and arrangement of parts described without departing vfrom my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

The combination with a catch comprising a shank having a hook-shaped pin-receiving outer end, and an integral rectangular enlargement at the juncture of said shank and hook-shaped outer end forming two flat faces at an angle to each other, of a guard of' gen- I in testimony whereof I have signed my eral channel shape pivotally connected to name to this specification in the presence oi 10 the shank, said guard having its 1nter1netwo subscribing Witnesses.
