CATCH FASTENER WITH LOCKING DEVICE FOR PINS, BROOCHES, ANI) THE LIKE.

Application filed .Tune 8, 1920. Serial No. 387,333.

To all whom t may concer/a.' within said box 7 by any suitable way, for Be it known that l, GUs'rAvn AN'roiNn instance by means of a stud 8 on its base,

RENAULT, a citizen of the French Republic, retaining a small helical spring against a residing at Paris, Rue Reaumur 37, Seine, small shoulder 10, and also by means of two in State of France, have invented certain lateral feathers ll-lQ, fastened on box 7, 50 new and useful Improvements in Catch corresponding with two notches 13 14, on Fasteners with Locking Devices for Pins, the strap. Said notches are vsomething Brooches, and the like; and do hereby dewider than the feathers, thus providing for clare the following to be a full, clear, and the required amount of clearance.

The system above described is able to be used for many various appliances, namely as a point-cover or protector for hat-pins.

What I regard as new and desire to secure by Letters Patent is:

l. A pin having a pocket, a yieldable catch normally urged into said pocket and adapted to be disengaged from the pocket upon a rotary movement ot' the pin, and a case for the catch adapted to guide the catch into the pocket upon a longitudinal movement of the pin and catch in the direction to remove the pin from the case.

2. A device of the character described comprising al pin` having a pair of pockets at diametrically opposite points with walls rounded longitudinal andl circumferential, the portions of the pin between the openings being left blank, a strap of resilient material having jaws at its tree ends adapted to yieldably engage in said pockets and guided by the curved walls of the pockets out of engagement therewith when the pin is turned, and a case receiving the strap and acting to force the jaws more firmly into the pockets on withdrawing movement olr the pin.

3. In combination'with a pin having a lateral pocket, a yieldable catch normally urged in the pocket and adapted upon a rotary movement of the pin to be disengaged from said pocket, a case to receive the pin and to hold the catch, said case and catch having' mutually tapered walls adapted to guide the catch into the pocket automatically upon an axial movement of the pin in a direction to withdraw the pin from the case,A

and yieldable means for independently urg ing the catch against the tapered wall of the case.

In testimony whereof I ailiX my signature in presence of two witnesses.
