Specification of Letters Patent.

' Patented May 3, 1921.

Application filed October 8, 1920. Serial No. 415,661. p

Be it known that I, Louis A. P eE, a

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.

This invention relates to improvements in safety. catches for plnssuch'as cuff pms,

beauty pins and the like.

My present invention has for itsobject to provide an improved form of keeper orgate member which is designed to close the opening'in the keeper-member of the catch and effectually prevent the joint of the pin-stem from being inadvertently removed therefrom. I

The nature and advantages of the invention will be better understood when the fol lowing 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 severalviews and wherein Figure'l 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 Fig. 6 is an edge view of the catch-mem-- ber, showing the gate-member in closed position therein.

Fig. 7 is a side view of my improved catch-member, showing the gate in closed position.

Fig. 8 is a side view of my improved catch-member, showing the gate in open position.

Fig. 9 is an edge view showing the rear of my improved catch. V

Fig. 10 shows a modification in which the free end of the gate member is offset later-' ally slightly to extend past the overlapping portion at the hook-end without notching the same.- citizen of the United States, residing at With reference to the drawings, 10 desigf nates the base or body portion of a pin to which the usual pin-stemll is pivoted in the jointed member 12, the opposite endof the'pin-stem beinglocked and retained in. my improvedsafety catch member 13. The body or keeper portion of .thisbatch-miem b'er, is'prefe-r'ably struck from sheet stock,

first into the form illustrated in Fig. 2, providing two hook- shaped arms 14 and 15 which are subsequently folded up against each other on the center line 16.

The inner surface 17 of each of these arms is preferably recessed slightly so that when the two armsare folded together a slot18" will be provided between them for the recep- 7 tion of a gate-member, presently described, and when these arms are so folded they provide a hook-shaped body or keeper portion having an open mouth 19 for thejreception of the pointed end of the pin-stem 11.

In forming the hook-shaped ends of these arms I preferably mak'ethe end'of the arm 15 slightly shorter than that of the arm 14 thereby causing them to overlap one beyond the other. I

The gate-member 20 is preferably formed increscent shape and of thin stock, the same being pivoted at 21 to swing in the slot 18 between the side arms 14 and 15. The free end of this gate is ofiset as at 22 to serve as a stop, to engage the inner surface of one of the side arms of the keeper and limit the outward or opening swing of the gate. a

It will be noted that when the gate is in closed position its free end swings past the extending portion 14 of one of the arms of the keeper and abutsagainst the end of the opposite arm, whereby a broken joint is formed to prevent an outward strain on the pin-stem from acting'directly upon the free endof'the gate to move it toward open position. In other words such an outward strain will be taken'by the extending-end of the keeper instead of being exerted upon the opening of the same.

serves as a friction to retain it inits slot,

' used.

The inner edge of one of the arms of the keeper is shown as being notched as at 26 to receive the outturned end 22 of the gate.

In some cases I offset the end of the gate member laterally as shown at 25 in Fig.10, whereby it will pass by the extending portion ld of. the hook end and so save notching the same as shown in Fig. 6'. Then again this-offset on the end of the gate when swinging back to open position.

My improved safetycatchis simple, practical and inexpensive "in construction and by 7 its use a pin-stem may be securely retained in the catch against accidental removal therefrom.- 7 e The foregoing description is directed solely toward the ,7 construction illustrated,

but I desire it to be understood that I re- V susceptible, the invention being defined and serve the privilege of resorting to all the mechanical changes to which the device is limited only by'the terms of the appended claims.

m I claim: I r

l. Asafety'catch comprising a keepermember having two integral hook-shaped arms folded upon each other with a-space between them, and a gate-member pivoted to swing in said space between said arms from the back of the hook toward the front thereof to close it. 1

2. A safety. catch comprising a keepermember formed of a pair of integral hookshaped arms folded together, the inner side walls of said arms being recessed to provide a slot between them, and a gate-member pivoted to swing in said slot from the back of the hook toward the front thereof to close it. 7 7 7 3. A safety catch comprising a keepermember having two integral hook-shaped arms folded upon each other with a space between them, a gate-member pivoted to swing in said space between said arms from the back of the hook toward the front thereof, the free end of said gate-member being offset, to form a stop to limit the opening swing of said gate. 7 p

a. A safety catch comprising a keepermember formed of apair of hook-shaped arms set side by 'side, the inner side walls of said arms being spaced toprovide a slot between them, the end of one hook arm extending beyond that of the other, and a gate-member pivoted to swing between said arms from the back of said hook toward the front thereof to close it, the free end of said gate being adapted to swing past the longer hook and abut against the shorter end thereof when closed. e

In testimony whereof I affix my signature? Lorne A. PAGE.
