My invention relates to safety catches for pins, and consists in the constructions, arrangements and combinations herein described and claimed. r 5 It is an object of my invention to provide a pin-keeper embodying a swingable hook member frictionally retained in locked po sition, thus preventing accidental disengage,- ment of the pin from the keeper.

A'further object of my invention is to provide a simplified construction of pinkeeper in which the pivot for the swinging hook member is positioned a substantial distance from the base of the keeper, thus-obviating damage of the pivot during mounting of the keeper upon an article of jewelry.

A still further object of the invention is theprovision of a safety catch wherein outward swinging movement of the pin will tend keeper. I a i Additional objects, advantages and features of invention will be apparent from the following description, considered in conjunction with the accompanying drawings, wherein: i

Figure 1 is a side elevation of an article of jewelry embodying my safety catch;

Figure 2 is an enlarged cross sectional view, on the line 2-2 ofFigure 1;

Figure 3 is a cross section on the line 33 of Figure 2; j

' Figure 4 is a detail perspective viewof the keeper member with the hook member detached. e

.In carrying out my invention I provide an article of jewelry, generally indicated by' the reference character 1, upon one end of which there is swingably mounted a pin 2 having'a piercing point '3confined within a keepers a I 7 The keeper 4 in the present instanceis formed from a single piece of material having a'base portion 5 adapted to be soldered or otherwise secured to the bar 1. The keeper i 4 is bifurcatedlongitudinally of its length to stud ;,member's extended therefrom, certain provide aslot 6 for reception of the pin 2,

the bifurcations extending from the outermost part of the keeper 4 and stoppingshort 5c of the base 5, as clearly. sho'wnin Figures to more efiectively lock the pin within the 'the keeper hook 11 so as to disengage the 2 and lj *Aslotlis also formed in the material 5 and extends at'right angles to: the slot 6 and-is of a width to accommodate a'keeperhook; The keeper being thus formed, studs 8 and 9' areprovide'd,extending at right angles to the base.-"' The studs 8 are apertured adjacent their'outerends, adapted to receive a pintle 10 uponwhich there is swingably' mounted a keeper-hook 11 e o 1 'iThe hookll has abill portion 12 adapted to flie jwithin the boundries of the' stud when'in: closed position, and one side of the bill is recessed, as at 18, adapted to register with a'lprotuberance 141 of the-stud 9; By; this construction-it will-be seen that the keeper=hook-11 will' be 'frictionally: held against accidental movement. 1 a Opposite. the bill 12;the-hook has asha'nk 15'of a length to extend closely adjacent the "E0 base 5,. and has an offset portion 161 definin v a gripping means 17 for swinging the 1100i 11. Iii-desired a kerf 18 may be formed in the offset {portion to accommodate a. finger nailof the user, forrmanipu'latingthe hook. As shown @111 Figure 2,the ofl'set portion 16 projects slightly inward of the base 5, forming a heel 19' resting upon the base 5 whenthehook is in closed position. With the heel'1'9 engaged with'the base as described,.outward pressure of thepin 2011 the bightfportionoi the bill 12'will efiect 10K}: positive; locking of the heelf19 with-the ase5.r

pin 2 engaged within the keeper 4, and it is desired to release the pin, the finger nail of the user is inserted in the kerf 18 and pressure exerted outwardly away from the bar 1. Such pressure will swing 90 protuberance 14 and aline the bill 12 with the studs8. With the partsin this position, the pin 2 will be free to move outwardly through the slot 6. i I claimt j 1'; A safety catch comprising a base having of which define 1a pin-receiving slot and others of which define ahook-receivingslot,

slot and arranged to extend across said first named slot, and said hook having a shank provided with a member projecting in an opposite direction to the bill of the hook end serving as a means for swinging the hook and as a means for limiting the swinging movement of said hook in one direction.

2. A safety catch comprising a base having an outwardly extending slot to receive a 7 pin, a hook swingably mounted on said base adjacent the outer end ofthe slot and ar-' ranged to close said slot at times, and said hook having an extension projecting inan opposite direction to the bill of the hook end adapted to engage said base to'prevent swinging of said; hook in one direction.

3. A safety catch comprising a keeper having a pin-receivingslot, a hook swingably mounted on said keeper, a friction detent between saidlhook and keeperto hold said-hook in closedposition, andsaid hook having an extension provided with a heel arranged to positively engage said keeper upon swinging movement'of said hook in one direction.

4. A safety catch comprising a basehaving a, pin-receiving slot, a hook member swingablymounted on saidbase, said hook member having an extension projecting in a direction opposite to thezbill of the hook end provided with a hee-li-adapted to engage said base in one movement thereof, and grip means on saidi extension outwardly of said heel for manipulating said hook. a

5. "A'safety catchcomprising a base provided'with studsprojecting therefrom and v defining slotszat right angles toone another,

a hookpivot'edrinone slot to the outer ends of twojvstuds, and having its bill normally lying" in'the slot between two, other studs, said hook extending over the other slot, the hookbeing'providedwith a straight shank normallyilying between the studs and having at its inner end on the side. opposite the bill of the hook, an; outwardly projecting member for operating the hook, the inner portion of the member engaging the base and limit- 7 ingthe inwardlyswingin of the hook. l
