SAFETY-CATCH.

' Specivation 0f Leftfslatent Patented June 28, 1921.

Application filed November 24, 1920. Serial No. 426,887'.`

To @ZZ whom t may concern:

Be it known that I, JOHN FIELDING, `a

citizen of the United States", residing Vat Providence, in the county of Providence and `State of-Ithode Island, have invented certion will be better understood when the fol-V 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 several views and wherein l Figure 1 is a side elevation Vshowing -my improved catch as mounted on. a base with the pin stem in engagement,therewith.

Fig. 2 is an end view of my improved catch member. I

Fig. 3 is a view illustrating the catch member as cut from sheet stock before being folded into finished shape.

Fig. 4L is a modified formof my improved catch. Y

IVith reference to the drawings, 10 desig nates a base plate which may be considered as representing` a brooch, cuff pin` or the like, to which the base portion 11l of my improved catch member may be attached or connected in any suitable way. This catch member is preferably formed of sheet stock having a body' portion 12 with two laterally, oppositely-extending wings 13 and 13. The upper end of this body portion is then bent over into hook form as at 111 providing aA broad-faced, hook-shaped hood with its upper lip or engaging edge 15 formed on an angle relative to the base of the brooch, the edge 16 of the lip Anearest the joint end .17 ofthe brooch `being longer or extending vnea-rer to the base than the opposite edge the end of the pin stem 2O may seat to be Y guided laterally into and out of the catch after its body portion has been sprung down to proper alin'ement-y to pass ksaid opposite lips as presently described.

It will be noted that the lower guide lip 13 on the edge of the catch opposite to that o f the downwardlyextending portion 16 on the hood, is somewhat longer thanthe lip '13'Llv opposite this downwardly extending portionl, whereby an angular space 21`is formed between the upper and lower edges or lips of the mouth or opening into the hook, necessitating the bending or springing downward the body portion of the pin stem, or that portion of the pin stem intermediate the catch and joint, out of its normal alineg ment or toward the base, to permit its end portion to pass said opposite extensions 13 and 1G in either ,entering Orleaving the catch.

I do not wish to be restricted to the angular shaping of the lips at the mouth, as any oppositely-projecting extending portions on the opposite lips such for instance as that illustrated in Fig. 4, which are out of Vertical alinement with each other and are so arranged that the'body of the pin stem must be sprung inwardly out of its normal aline ment toward its base, to permit its end portion to pass these said extensions in either entering or leaving the catch, will fall with- :in .the spirit and scope of this invention.

It is found in practice that normally when the brooch or pin which is inoperative position andthe pin stem 10 has been passed through the fabric-to which the brooch is atltachedy a bunch-of the fabric between the base 10 and pin stern 2O normally crowds or forces the pin stem up into the hood portion ofthe catch member and the natural pressure of this fabric against the pin stem is to bow orbend it outwardly or away'from the base, or inthe direction opposite to that necessary to cause it to be released by the Cat/Ch! Y it is necessary to be pressed and sprung inf wardly by the hand of the userin order to which effectuallyprevents the ina place it in the necessary alinement to be released from the catch.

The device is extremely simple andypractical in construction and effective in its'operation and by its use a safety catch device is provided without the use of movino' parts7 dvertent release of the pin stem from its catch.

The foregoing description is directed solely toward the' construction illustrated, but I desireit 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 appendedclaims.

I claim: i

l. ,A catch member for pin tongues com prising a broad-faced hook-shaped hood, a lower guard and lguide lip extending forwardly beyond the front edge of said'hood, and oppositely projecting extending portions o n said hook and lower lip out of vertical alinement with each other guarding the mouth of the catch and so arranged that the body portion of the pin tongue must be sprung inwardly out ,of its normal alinem'entto permit its end portion to pass said extensions in either entering `or leaving said catch.

Q. A catch member for pin tongues havingv 'a base, a-hoolrshaped hood portion'open at i being both set at an angle to theplane of theL base, whereby the body of the pin tongue must be sprung inwardlyl out of its normal ahnement to elther enter or leave said catch. 3. A catch member for pin tongues having a base, a hookashaped hood portion open on.

its vside to receive the pointed end of the pin tongue, said catch being provided with a pair of spaced apart'lower guard and f guide lips extending forwardly vbeyond the front edge of the hood vto engage. and guide the pin' tongue laterally into the hood, the entering edge of .said hood and said lips beV ing set to forma laterally-inclinedV mouth to either enter or leave said catch.

In testimony whereof IY aiix m signature. v JOHN FI LDING.
