BRACELET-LOCK. I

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed ctober 24, 1916. Serial No. 127,415.

To all whom t may concern:

Be it known that I, EDMUND R. NnELiNG, a citizen of the United States, and a resident of the city of New York, Woodhaven, borough of Queens, in the county of Queens and State of New York, have invented a new and Improved Bracelet-Lock, of which the following is a full, clear, and exact description.

My invention relates to a lock for bracelets. The object thereof is to provide a lock which cannot be accidentally operated and thereby unlocked. u

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the'novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

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

Figure 1 is a top plan view of the socket, certain parts of which are broken away to show the details of construction;

Fig. 2 yis a top plan view of the stud plate cooperating with the socket and complementing the same to form the lock;

Fig. 3 is a side view of the stud plate;

Fig. t is a section on line 1 -4, Fig. l;

Fig. 5 is a bottom plan view of the socket, the slide or bolt being shown in a different position from that shown in Fig. 1;

Fig. v6 is a section on line 6 6, Fig. 5;

Fig. 7 is a cross section similar to Fig. 1, the stud plate being shown 'in engagement with the socket and locked thereto by the slide;

Fig. 8 is a section on line 8 8, Fig. 5;

Fig. 9 is a section on line 9-9, Fig. 1; and

Fig. 10 is a perspective view of the slide or bolt.

Referring to the drawings, the socket 11 is in the shape of a shallow casing the contour of which may vary in accordance with the shape of the bracelet to which it is to be attached. The socket is preferably open at the end where it ,is provided with a loop 12 by means of which it is attached to the structure of the bracelet. A pair of parallelly-spaced strips 13 are provided within the socket to extend from the front to the rear edges thereof. These strips reinforce the top and bottom of the socket and constitute the guides for a slide or bolt 14 for which the front edge has an opening, through which opening the lid 15 of the slide projects toforma grip for manipulating the slide. The movement of the slide in the socket is limited by the engagement of a slot 16, providedv in the bottom of the socket, with a pin 17 provided in the slide.

The top of the soc'ket is rendered yielding and rmade to bear on to the slide 14 so that the friction between the two is increased and, consequently, a greater effort is necessary to move the slide from the position shown in Fig. 1 to that shown in Fig. 5. To further assure the difficulty of an accidental displacement of the slide in the socket, the slide isprovided in the bottom thereof with a groove 18 which is engaged by a projection 19 provided on the bottom of the socket. This projectionsnaps into a depression 20 in the groove 18 when the slide is fully engaged in the socket, and in which position there will be but slight possibility of displacing the slide accidentally.

The socket 11 has a pair of spaced openings 21 traversing the top and bottom of the socket. Each opening severs the adjacent strip 18 into two parts so that a portion of each of said openings is obstructed by the slide 14 (see Fig. 1). The slide is provided with circular recesses 22 adapted to clear the openings 21 when the slot 16 and the in 17 prevent a further outward movement of the slot (see Fig. 5).

In this position the stud plate 23 may be engaged to the socket as the studs 24 of the plate are spaced so as to enter the spaced openings 21 in the'socket. To lock the stud plate to the sockets, the studs 24: are notched to allow an inward movement of the slide 14 while the studs are in the opening 21. The notches 25 are preferably arcuated so that there is a wedging action between the slide and the stud. This action further increases the resistance to an accidental displacement of the slide when it is pushed home, as shown'best in Fig. 9. The stud plate is provided with suitable means whereby it may be attached to the'bracelet structure; and it is self-evident that the shape of this plate, aswell as the shape of the socket, will vary in accordance with the design of bracelet with which it is to coperate.

I claim:

1. In a lock of the class described, a socket in the shape of a shallow casing, a slide in said casing' presenting alip at one edge thereof whereby the slide may be manipulated in said socket, means limiting the movement of the slide in the socket, said 'casing having' an opening` and said slide havinga circular notch adapted to register with said opening' in a predetermined position of said slide, and a plate having a stud for engaging' the aperture of the socket, said stud being notched to clear the way for the movement oi' the slide in the socket whereby said plate may be locked to the socket, said socket having' yielding means for engaging the slide to oiier a greater resistance to the movement of the slide in the socket, said socket and slide having' coperating means influenced by the yielding' means of the socket to offer a greater frictional resistance to the slide when the same in the socket.

2. In a lock of the class described, a socket in the shape of a shallow casing, parallellyspaced guiding strips in said socket, a slide in the socket l0uided by the strips, said socket having a pair of spaced openings, each of said openings severing' a guiding is fully engaged strip, said slide having' a notch at each of its longitudinal edges adapted to register with a corresponding opening' in the socket, means limiting` the movement of the slide in the socket whereby the notches may be brought into register or out of register with the openings or' the socket, said slide having' a groove, said socket having a projection engaging' the groove, said projection normally forcing' said slide against the top oi" the socket, said socket having' the top thereof yielding to increase the resistance to displacement ot the slide in the socket, said groove in the slidehavinga depression at one end thereot1 adapted to be engaged by the projection under the action of the yieldingr top and thereby further increase resistance to the displacement of said slide in the socket, and a plate having' spaced studs adapted to engage the apertures in the socket, each ol" said studs having a notch for clearing the slide whereby said slide may be moved while the studs are engaged in the openings of the socket, thereby locking' the plate to the socket.
