SAFETY LATCH Filed Jan. 10, 1944 2 Sheets-Sheet 1 INVENTOR. farm; S/mfh 1? Patented Sept. 14, 1948 Aaron Shatkin, Matawan, N. J. Application January 10, 1944, Serial No. 517,647 I 6 Claims.

The present invention relates to latches par- I ticularly adaptable to articles of jewelry employing a pin for a fastening means, as on brooches and the like.

An object'of this invention is to provide a novel and improved latch for brooches and similar articles, which is easy to lock and unlock.

Another object hereof isto provide a novel and improved latch means of the character mentioned, in which the pinpoint is shielded while the latch is closed.

A further object of this invention is to provide a novel and improved article of the type set forth which is reasonably cheap to manufacture, simple to manipulate andeflicient in carrying out the purposes for which it is designed.

Other objects and advantages will become manifest as this disclosure proceeds.

To accomplish these objects, essentially, a pivoted pin is otherwise moveably mounted on a frame carrying a socket for receiving the free end of the pin which is pointed, and means to prevent movement of the pin when within the socket.

In the accompanying drawings forming part of this application, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 shows a closed latch embodying the teachings of this invention, partly in section.

Fig. 2 is a plan view of Fig. 1; the latter being a view which'also may be described as a section taken along lines II.

Fig. 3 shows said latch in open condition.

Fig. 4 is a perspective view of the pin-point socket employed in the article illustrated.

Fig. 5 is a side view of Fig. 4.

Fig. 6 is a view similar to Fig. 3 embodiment of this invention.

Fig. 7 shows the article of Fig. 6 in closed condition, partly in section.

In the drawings, the numeral I0 designates an ornament carried on a frame indicated generally by the numeral II, which has associated therewith a swingable pointed pin I2, for attachment to a wearer's garment for instance. One end of the pin I2, is pivotally secured at I3 to a link I4, while the other end of said pin is adapted to be received and housed in member designated generally by the numeral I5. The link I4 is provided with a longitudinal slot I6, through which is positioned a pin I'I, secured at its ends in a pair of bracket members I8 which are part of the frame. It is evident that the link I4 is both slidable and swingable about said pin with respect to the frame element II. The frame also includes I9, which serves as a socket or track to receive the of another link I4 therein and maintain same against rotary movement about its axis pin I1. The element 20, may be so bent in slight convergent relationship. with element II, that the fit of link I44 in .said socket is snug when shifted therein manually which may be facilitated by the tab I4. A second. tab I4" extending from said link, serves to limit the movement of the pointed pin I2ab0utitsaxis pin I3. The free end of element 20 and element II serve to limit the scope of rotary movement of the link I4 about its axis pin I'l.

The pin point housing I5, has a guide slot I5" which leads the point pin I2. into socket bore I5". Itis to be noted that axis pin I1 is intermediate the pin point socket I5 and I the. link socket IS, in close proximity to the latter.. The. tininess of the various elements and particularly in some constructions, the springiness of the pin member I2, permits proper operation of this latch, whose mode of use will now be set forth.

Taking hold of the article in condition as shown in Fig. 3 when the pin I2 is free of socket I5, and link I4 is not engaged within socket I9, and in position substantially normal to frame II, said pin is laced in the usualmanner through a fab-. ric. garment and swung about'pin I3 so that the pointed end thereof may be placed within slot I5 of the housing I5 which shall guide its movement into the socket bore I5. By turning the link I4 now, so that it shall lie in alignment with pin I2,

said link will enter its socket I9. The latch is now in closed condition as illustrated in Fig. 1;

the article is securely worn, and the point of pin I2 is safely housed. To open the latch and remove the article from the wearer, take hold of tab I4 and slide the link out of socket I9, whereby pin I2 will move further into its socket bore I5 which is purposely made long enough for such purpose, and when said link I4 is free of member 29, it is swung away from frame element I I' again into position as in Fig. 3, whereupon pin I2 will withdraw from socket I5, and the latch. will be open for withdrawal of pin I2 from wearers garment.

In the embodiment illustrated in Figs. 6 and 7, the pin 22 is pivotally mounted at 23 to a link 24, which in turn is pivotally mounted. to the bracket 28. The axis pin 23 also carries thereon pivotally mounted, a cam member 26 which is adapted to be shifted by handling prong 26', so that said cam. frictionally engage the bracket member 28 to lock the pin against movement after the pointed end of the latter is set within the socket member I5. The frame member is here indicated by the numeral 2|.

By turning cam 26 away from engagement with the bracket member 28 of the article of Fig. 7, the latch may be opened.

For purposes of definition in the claims, the bracket members l8 and 28, may be deemed as part of their respective frames.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the specific;

description herein be'deemed illustrative and not restrictive, reference being had to the following claims rather than to the particular embodiments herein to indicate the scope of this invention.

I claim:

grip ed by 'said arms.

6;In an article of the character described, a

1 frame, a link having a longitudinal slot, an axis 1. In an article of the character described, a

frame, a link, means on the frame holdingsaid link in swingable and slidable relation to the frame, a pin pivotally secured at one of its endsto the link; the axes of rotation of the pin with respect 'to the link and of the linkwith respect to theframe being paralleL'a member having a socket carried by the frame; the free end of the pin being" adapted to be positioned within said socket; and an element'carried by the frame in engagement with said link whereby the link is heldagainst rotary movement and against sliding movement away from the socket; said link being'adapted to be'slid towards the socket until released from the engagement element and free for rotary movement about its axis on the frame; the pin, when its freeend is within the socket, moving further into the socket during movement of the link away from the engagement element, and the pin-becoming free of the socket, upon movement .cf the link about its axis on the frame in a direction away from said socket.

'2. An article as defined in-claim 1,.including a stop means carried by the link in the locus of movement of the pin with respect to said link; saidy'stop means being adapted to restrain rotary movement of the pin about its pivotal connection on the link.

3. An article as'defined in claim 1, wherein the pin socket element is provided with an entrance slot communicative with the socket bore; said entrance 'slot lying in the locus of movement of the end portion or the free end of thepin.

pin fixedly mounted on the frame and positioned through the slot, whereby the link is slidable on said axis pin in a direction normal to the axis of said axis pin, and swingable about said axis,

,a pin pivotally secured at one of its ends to the link; the axis of rotation of the pin with respect to the link and of the link with respect to the frame, being parallel, a member having a socket carried by the frame the: free end ofthe pin being adapted to be positioned withinsaid socket;; and an element carried by the frame in engage-3 ment with said link whereby the linkisheld against rotary movement,- and against sliding movement away from'the socket; saidlinkbeing adapted to be slid towards the socket until re-.

leased from the engagement element-and free -for rotary movement about. itsaxis on the frame;

the pin, when its free end is Within the socket;

movement of the link about its axis on the'frame.

in a direction away fromsaid socket;
