I. Application May 9, 1935, Serial No. 20,625 2 Claims. My invention relates to improvements in spring catches for use in detachably securing the ends of bracelets, chains and other articles together. It is preferably constructed in a form to detach 5 ably secure the ends of flat articles together, such as a bracelet made out of pierced flat members hingedly secured together, after said bracelet has been laid around the wrist. An object of my invention is to provide a catch for use in detachably securing the ends of said articles together, the prong portion of which may be an integral part of, or be rigidly attached to 1 an adjacent flat article portion and the compart ment portion of which may be rigidly attached to an adjacent fiat article portion, preferably rig idly attached in such a manner that the catch itself may appear to be a component part of the adjacent flat members and which is so designed to be of such small proportions as not to inter 20 fere with the pierced or other designs on the flat adjacent portions of the bracelet or article. A further object of my invention is to provide a spring catch, sure and positive in its action and constructed of a minimum number of parts. A further object of my invention is to provide 25 a spring catch which will automatically lock, be permanently retained in locked position by a spring and which may be readily and easily de tached after depression of the slide member 30 thereof. A further object of my invention is to provide a catch means which will permit pivoting be tween the parts thereof in a locked position in order to readily bend around the wrist. 35 These and such other objects of my invention as may hereinafter appear will be bestI under stood from a description of the accompanying drawing which illustrates an embodiment thereof. In the drawing, Fig. 1 is a front elevation of 40 my improved spring catch in locked position with both the prong means and compartment por tion thereof rigidly attached to the adjacent flat bracelet portions. Fig. 2 is a rear elevation of the parts of my 45 invention shown in Fig. 1. Fig. 3 is a perspective view of the parts of my invention shown in Fig. 1 with the prongs de tached from the compartment portion. _ Fig. 4 is a vertical, longitudinal sectional View 50 taken along the line Ll-ll of Fig. 3 through the (Cl. 24-230) adjacent thereto and about to be inserted within the slots of the compartment portion. In the drawing, wherein like characters of ref erence indicate like parts throughout, Ill gener ally indicates a spring catch constructed in ac- 5_ cordance with my invention, as stated adapted for use in detachably securing the ends of bracelets, chains or other preferably flat articles together, comprising prong means I2 and a compartment member I4. As stated hitherto, my invention is 1o particularly adapted for use in. bracelets, having flat pierced or otherwise ornamented portions hinged together to make up the bracelet, or other solid portions immediately adjacent the catch I0 and as shown in my preferred embodiment l5 includes the rprong means I2, rigidly projecting from one end I6 of a flat article, and the com partment member I4 of my invention having the inner vertical edge 20 thereof integrally attached to the other end 22 of the bracelet or other Ilat article, each end I 6 and 22 in the embodiment shown comprising the flat members I6 and 22 of a bracelet each having respectively, the prong means I2 and compartment member I4 integrally attached thereto. 25 In the preferred embodiment of my invention shown, I provide two flat prong means I2, each vertically spaced from the other and rigidly pro~ jecting from the end I6 of said fiat article, ñrst outwardly as rat 24 substantially in the plane 3 thereof and then substantially at right angles forwardly as at 26 and with the front 28 thereof terminating in a cam surface 30 inclined rear wardly from the top to bottom. Each forwardly projecting portion 26 is also provided with an 35 indentation in a horizontal edge thereof, in my preferred embodiment the indentation 32 in the bottom edge thereof. The other cooperating por tion of my invention rigidly attached to the oppo site end 22 of said bracelet comprises in. the.v em- 40 bodiment shown an oblong hollow compartment member I4 having the inner vertical edge 20 thereof rigidly secured by solder or by other means to said end 22 of said bracelet to integrally project therefrom, it being obvious that if de- 45 sired the entire ñat portion 22 of the bracelet and the compartment member It may be stamped or molded from flat stock and the compartment member formed by bending the ends and edges thereof over to form said compartment member 50 compartment member. I4. Fig. 5 is a vertical cross-sectional view taken along the line 5--5 of Fig. 4 through the com partment member, showing in sectional elevation with slot means 36 in a vertical wall thereof, in the embodiment shown the aligned slot means 36 and 31 in the rear and front Walls thereof sim the prong means of my invention immediately ilarly spaced to receive the forwardly projecting 55 Said compartment member Ill is provided 2,098,46 1 2 portions 26 of said prong means I2. Said com partment is also provided with a hole 38 in a curely lock said prong means within said com partment member. horizontal wall thereof, in my preferred embodiment the hole 38 in the top wall 40 thereof. To provide the positive locking member of my invention, I provide a preferably flat slide mem ber 42 vertically slidably mounted in said com To release the portions 56 of said slide from within the indentations 32 of said prong means ' to permit said prong portions 26 to be withdrawn rearwardly from the aligned slot means 36 and 31 in said compartment member and aligned partment member and of a size to substantially. fill the center and one end of said compartment, holes 48 in said slide member, the extension 54 is manually depressed to bring said slide slot means 10 in my preferred embodiment the center and upper partment slot means 36 and 31 to permit ready withdrawal of said prong means I2 from said aligned slot means 36, 31 and 48 and thus from said compartment member I4. It is apparent 48 into alignment with said front and rear com end of the compartment 44 of said hollow oblong>` compartment member I4. In the preferred em bodiment shown, said slide- member `42 is pro vided with an aligning lug 46 projecting verti-` ythat if desired, the cam surfaces 33 on the end 15 cally therefrom, in my preferred embodiment of the-prong ,means I2 and the cam surface 52 the aligning lug 46 projecting vertically down-ï. on the rear surface of the portions 56 of said slide wardly centrally thereof. Said slide member 42w i means >may be dispensed with, in which case in is also provided with slot means 48, in my pre secure the prong means I2 within the ferred embodiment similarly vertically spaced to _orderrto compartment member I4, it will be necessary to 20 said prongs I2 and compartment slots 36 and 31. the extension 54 to depress said slide 42 To permit the automatic locking of my improved depress to bring the aligned slot means 48 thereof into prong means I2 within said compartment mem alignment with the aligned slot means 36 and 31 ber I4, I provide the rear portions 50 of said on the front and rear of said compartment mem slide immediately adjacent saidslot' means 48, in ber I4 when said prong means may be readily in 25 my preferred embodiment immediately below serted within said aligned slots and after inser said slot means, with outwardly, in my preferred embodiment downwardly tapered cam surfaces 52 adapted to cooperate with the cam surfaces 3Q on said prong ends 28 on insertion of said 30 prong means l2 through said compartment slots 36 to abut the adjacent'portions of -said slide member 42 to cause vertical movement of said slide member 42, to align the slot means48 there in with the slot means 36 and 31 in said com partment member to permit the prong means 26 to pass through said then aligned slot means 36, 48 and 31 for locking purposes. Said slide mem ber 42 is also provided with an extension 54 pro 40 tion thereof pressure may be released on the slide extension 54 permitting the spring means to raise said slide member 42 to permit the portions 50 thereof to slide into the indentations 30 32 of said prong means I2. While I have shown the spring means 56 as being mounted on the' lower portion of the compartment member I4, it is obvious that it may be mounted in the upper portion of the compartment member I4, the ex 35 tension 54, hole 38, indentations 32, cam mea-ns 3!) and 52 being correspondingly reversed and if desired, it is also obvious that the prong means . To normally urge the slide 42 to bring the por-v may be straight throughout and inserted laterally within the compartment member I4. 40 It is apparent, therefore, that I have provided a novel type of spring catch, particularly adapted in detachably securing the ends of bracelets, chains and other preferably flat articles together tions 58 thereof within the indentations 32 of said prong means, I provide the spring lmeans 56 having one end thereof adapted to» abuta com parts, positive in its action and which may be readily mounted on the ends of articles and be partment end and the other end thereof vadapted of such aY small size as not to interfere in any jecting vertically, in my preferred embodiment upwardly through the compartment holev 38, said extension 54 being substantially the _height of the desired vertical movement of the slide 42. constructed of a minimum number of simple 45 to abut a slide member end, in my preferred em Y manner with the symmetry of design thereof and bodiment the spring 56 comprising a coil spring with the other advantages explained above. 50 50 mounted in the lower portion of the compartment It is understood that my invention is not lim 44 to have the lower end thereof rest on `the ited to the specific embodiment shown and that compartment bottom 58 and the upper end there various deviations may be made therefrom with 55 of surround said slide member aligning lug> 46 and abut the bottom surface 60 of said slide member. ~ . It is thus apparent that with this construction and employing the cooperating cams 30 and 52 on the respective prong ends 28 andslide portions 60 58 that as shown in Fig. 5 on insertion of the prong ends 28 through the compartment slots 36, the cam surfaces 30 will abut the cam surfaces 52 on the slide and cause downward vmovement of the slide 42 compressing the spring 56 until the forwardly projecting portions 26 of the prong means are completely inserted within the aligned slot means 36 and 31 in the rear and front of said compartment member I4 and the aligned slot means 48 in said thus depressed slide mem 70 ber 42 until the front ends 28 of said prong means project through said compartment mem. ber and the portions 50 of said slide member 42 are free under pressure ofthe spring means 56 to slide upwardly intofthe indentations 32> in 75 the lower surface of said prong means .I2 to se-k out departing from the spirit and scope of the appended claims.
