CATCH.

lApplication tiled January 26, 1925. Serial No. 4,780.

loss of'ornainentality or facility in connection and disconnection, which may be simple in'construction, not hable to loss of any of its parts when disconnected, and which shall` be practically indistinguishable except on close examination from the other portions of a bracelet.

For purposes of illustration one illustrative form of the invention is shown in the accompanying drawings, in which'z Fig. 1 is an elevation of the invention, with its parts in closed position, showing its relation to other links of a bracelet;

Fig. 2 is a corresponding view of the invention with its parts in released position;

Fig. 3 is an end view;

Fig. 4 is a rear View; and

Fig. 5 is a top edge view of the invention;

Fig. 6 is an elevation of a locking plate;

Fig. 7 is a horizontal section on the line 7-7 of F 4;

Fig. 8 is a vertical section on the line 8-8 of Fig. 4;

Fig. 9is a vertical section on the line 9-9 of Fig. 4; yand Fig.`10 is an edge view of the cover element of the lock.

The'illustrative embodiment of the invention consists of a main, base, or body portion 1, and a cover portion 2. The main or base portion consists of a base plate 3 approximately twicethe length of an Ordin bracelet link section B. To the plate 3 at a point substantially midway between its center vand one end is pivotally secured upon a rivet 4 a swinging lock plate and lever element comprising a portion 5 ofa length in one dimension about equal to one-half the length of the base plate 3 and of a width equal to the width of the latter. l Portions of the opposite ends of the lock plate are adjacent bracelet section or with the other parts of the base portion.` From the plate 5 a lever portion 5 projects at one corner and provides a button 7, due to a thinning of the material between the button and the main body of thev plate 5'. The plate 5 is provided with a pair of arcuate slots struck from the center of the rivet 4., these slots being substantially smaller at one end than at the other and each including a practically circular openingl Sinerging into an arcuate slot 9 substantially narrower than the diameter of the circular recess. @ne of the slots also includes at the opposite side of the circular opening from the arcuate slot 9 a relatively narrow curved slot 10 which cooperates with an upset boss 11 on the base plate 3 to stop the swinging movement of the plate 5 in a position in which the portions 8 of the slots will overlie a pair of openings 12 in the base plate 3. rlhe juncture of the slot 10 with the larger portion 8 of the slot is marked by a shoulder 13. This shoulder cooperates `with the boss l1 and serves to provide a yielding detent for the plate 5 when the latter is in locking` position. rEhe cover portion 2 has an offset end 15 with a slot` 15 therein to provide a connection to one end of a bracelet and has a pair of parallel pins 16 projecting therefrom. The pins 16 have enlarged heads 17 of a size to pass through the larger portions 8 of the slots in the plate 5 and through the openings l2 in the base plate 3, while the shank portions of the pins are slightly smaller than thel portions 9 of the slots in the plate 5. lff desired the surfaces of the heads 17 towards the cover plate 2 may be slightly beveled to facilitate initial movement of the plate towards locking position.

At the opposite end ofthe plate 3 from the plate 5 a plate 13 is mounted in spaced relation to the plate 3 to providev a recess 19 in whichl a guard 2O is pivoted. The plate 18 has at either end reduced shoulders 21 bent at right angles to the plate and seating against the plate 13. The shoulders 21 terminate in further reduced tongues 22 one of which passes through a recess 23 and the other through a notch 24 at the end of the plate 3, and when bent fiat these tongues loch the parts together. The plat-e 3 has recesses in which the tongues seat. Between the plates B and 18 the guard 2O is pivotally mounted. The guard is, as villustrated, made from a stamping which at one end has had ears 2i' bent together to form a portion substantially filling transversely the space between the plates 3 and 1S. The other end of the guard has an elongated naroiv slot 28 adapt-ed to spring over the button 7 When the plate 5 is in locking position. The guard pivots on a sWaged projection '29 extending into an openingBO in the plate 3. The outer surfaces of the plates 2 and 18 may be engraved, oi decorated in any desired manner to harmonize with the general design of the bracelet and the opposite ends of the bracelet secured in any suitable manner to the members 1 and 2.

The mode of operation of this catch Will 'be readily apparent. With the parts in the posi-tion shown in Fig. 2, lthe plate 2 may be moved to pass the pins 16 through the slot-s in Ithe plate 5 and through 4the openings 12 in the plate 3. The plate will then be swung to a position in which the button 'i' projects vertically upward yand the slots 9 will thereupon pass under the heads 17 of the pins 1G and-lock the latter against Withdraival. The boss 11 `Will cooperate With the shoulder 13 to lock the plate 5 non-positively in the position it then occupies, but the guard 2O may be swung doivn and its slot sprung over the button 7 to prevent positively the swinging of the plate 5 requisite-for release of the element 2. "When it is desired to release the clutch, the operations Will be reversed.

l/Vhile I have herein described one specific embodiment which my invention may assuine in practice and Which Well fulfillsthe objects set forth above, it will be understooi'l that various Lmodications falling Within the scope of the appended claims may be made Without departing from the invention.

l claim:

1. A safety catch comprising a pair of cooperating separable elements, one carrying a pivoted locking member, and the other a vplurality of projecting portions simultane- Aously engageable by said pivoted locking member to 'hold said elements together.

2. A safety catch comprising a pair of co gage at least two of said portions to lock said elements together, and means cooperat ing` with' one of said separable elements to prevent movement thereof during its engagement with the other of ksaid separable elements.

4. A safety catch comprising a pair of cooperating separable elements, one carrying a plurality of projecting portions, the other having recesses receiving said portions and also carrying means pivot-ally movable to engage each of said projecting portions to lock said elements together.

6. A safety catch comprising` an elementv having a pair of recesses therein and carrying upon a pivot intermediate said recesses a locking plate provided `With a ypair of slots swinging over said recesses on movement of said plate relative to said element, and a second element carrying projections insertible through said slots into said recesses, said plate vinterlocking With said projections on pivotal movement thereof in one direction.
