SPECIFICATION forming part of Letters 3? Application filed October 6, 1881. Serial No. 251.6!2.

To all whom it may concern:

Be it known that l, CHARLES TESKE, a citizen of the United States, residing at Hartford, in the county of Hart-ford and State of Connecticut, have invented certain new and useful Improvements in Spring Catches for .Vatch- Cases, of which the following is a specification.

My invention relates to spring-catches for watch cases; and the main objects of my invention are durability and general efficiency in operation and simplicity of construction.

In the accompaning drawings, Figure l is a plan View of my catch and attached dust-rim as applied to a watch-case, the latter being I mainly in section. Fig. 2 (which, as well as all the following figures, except Figs. 45 and 46,is on an enlarged scale) is a front elevation of my catch, the push -pin being shown in transverse section. Fig. 3 is a transverse section of the supporting-rim for my catch, the plane of section being near one end of said rim. Fig. t represents in detached plan views the catch, the springs, and the supportingrim, together with the ends of the dustband secured thereto. Figs. 5 to 47 represent various modifications of my improvements, which figures will be more particularly referred to in describing each modification.

A designates the watclpcase provided with the ordinary windingstem, which also serves as the pnshpi n a. My improvement, however, is not to be confined to stenrwiuding watches, as any push-pin that will move the catch inwardly to disengage it is for the purposes of my invention the full equivalent of the pushpin a. In this connection it should be noticed that the puslrpin need not be located within the stem of the ring orbow, but may be attached directly to the catch and project through the case at one side of the stem, as shown in Fig. 43. g

The engaging end of the catch B is substair tially of ordinary form, while its body portion is provided with laterally-extending arms I) b. The body of the catch and its arms I) b are fitted to notches and recesses in the supportingrim 0, to which rim I prefer to secure the dust-band c by attaching its ends to the respective ends of the rim 0. While the dust band makes the device more complete, it is evident that my supportingri m and catch may stem: No, 388,157, dated August 21, 1888.

be used without the dnstband. The support ing-rim is intended to be received in the usual space within the edge of the case and firmly secured to the ease in the position shown in Fig. 1, the dust-band covering and closing that portion of the space that is not closed by the supporting-rim. The shape in cross-section or end view of the supporting-rim is shown in Fig. 3, from which it will be seen that the upper and lower flanges of the rim form a longitudinal recess that is open at the outer edge of said rim.

lose the terms upper and lower with reference to the position illustrated in Figs. 2 and 3. The middle portion of the upper flange is cut away or notched, as at c, Fig. 4, to permit the body of the catch to be received therein, while the arms I) I, on each side of the catch lie within the recess in the supporting rim. \Vithin this recess I also secure a suitable spriug or springs-ms, for instance, the springs d d-secured by screws to the rim 0, with their ends pressing outwardly against the arms bl) of the catch. The push-pin a is arranged to press against the catch,so that pushing inwardly on said pin will move the catch inwardly against its springs and release said catch from the lid of the case, (the catch may be applied to either the front or back lid,) and when the push-pin is released the catch will be returned to its normal position by means of the springs. In closing the case the lid strikes the bevel of the catclnand causes it to slideinwardly. Meanwhile the arms and base of the catclnresti ng upon thelower llangeof the supportingrim, furnish a firm support for the catch and prevent it from moving in the same direction as the contacting edge of the lid which is pressed upon it, and therefore it cannotmove away from said lid except by sliding inwardly. As soon as the projection on the lid has passed by the lip on the catch, the lat ter snaps into place under the influence of its springs. By this construction, which thus holds the catch closely against the lid, the lid can be titted to shut very tight and close and yet have the catch properly engage therewith.

While I prefer the COllStIllClilOll illustrated in Figs. 1, to 4,inclusive,a1:id will base my most limited or specific claims thereomit is evident that some features of my invention have a broader application and that some of the advantages of my improvement may be reaped from modified constructions, some of which are as follows:

Figs. 5, 6, and 7 show one modification, in which Ipreferably attach the same dust-band c in the same way, the supporting-rim O and catch B being shown separately in Fig. 5. The rim is of H form in cross'section, as shown in Fig. 6,thereby forming recessesin the top and bottom. It is notchedin the middle to receive the body of the catch, and the arms I; I) rest and play in the upper recess and are pressed upon by springs which are the same as those first described and act in the same way. In order to hold the catch from working upwardly I secure to its under side the plate f, Fig. 7, which rests in the under recess or groove of the supporting-rim. In this Fig. 7 the supporting-rim O is illustrated in a central longitudinal section and the push-pin a in transverse section.

Figs. 8 and 9 illustrate the supporting-rim O as made with only one flange forming the recesss in the form of a rabbet, as shown by the transverse section, Fig. 9. The catch B and rim 0 are shown detached in Fig. 8, the middle portion of the rim being notched to receive the body of the catch B, as before described, the same springs (Z (I being attached to press upon the arms I) b of the catch, as before described. The arms I; I) rest upon the bottom flange of the supporting-rim and support the catch against moving with the lid; but the upper side of the arms will rest directly against the case on that side of the rim.

Another modification is shown in Figs. 10

and 11, which is the same as the construction first described, except that instead of the arms b b to hold the catch within the supportingrim it is held by guide-pins y g, which enter corresponding holes in the catch B. Fig. 10 shows the rim and catch detached, the position of the holes in the catch for the pins be ing indicated by broken lines; and Fig. ll'is a transverse section of the supporting-rim 0.

Another modification is shown in Figs. 12, 13, and 14, inwhich the supporting-rim is recessed at the bottom, as shown by the transverse section, Fig. 13, and the catch B is supported therein so as to slide out and in on the pins h h, which extend through corresponding holes in the body of the catch, as shown most clearly in the transverse section, Fig. 14, one of said pins being shown in elevation in said figure. Fig. 12 shows the catch and supporting-rim detached. Springs like springs (Z (Z are designed to be secured within the recess of the rim with their free ends pressing against the back of the catch at each end.

Fig. 15 illustrates another modification, the rim 0, spring j, and catch B being shown sepa rately. The supporting-rim is provided with projections k, which enter corresponding holes in the arms I) b of the catch B, said holes being indicated by broken lines. A spring, 3', liesbetween these projections and presses against the back of the catch B. It is prevented from working out of place by two pins, Z Z, which extend through holes in the spring, the body of the catch being also provided with holes to register with the pins Z Z.

The modification, Figs. 16 and 17, is practically nothing but an inversion of the parts shown in Figs. 1 to 4, the recess being on the inside instead of the outside of the supporting-rim, a section of the rim being shown in Fig. 17 and the parts being separately shown in Fig. 16. i

Figs. 18 and 19 show a modification in which the supporting-rim O has a single flange, m. notched at the middle to receive the body of the catch B,while the arms?) I) of the catch are recessed to fit said groove,as shown by the re spective sectional views through said rim and one arm of the catch in Fig. 19. The springs d cl, as before described,bear against said arms. Pins or projections g g, with corresponding holes in the catch, may be employed, ifdesired;

but the arms b b, recessed as described, and resting on the flange on, will furnish a proper support for the catch without these pins.

In the modification, Figs. 20 and 21,the supporting-rim is grooved or recessed at the top, as shown by the section, Fig. 21. The rim and catch are shown separately in Fig. 20. The arms I) I) rest in the groove and are acted on by the springs d d, as before described, and the upper sides of the arms rest against the case to hold the catch in, as in the construction shown in Figs. 8 and 9.

In the modification, Figs. 22 and 23,the supporting-rim is recessed on the inner edge, as shown by the section, Fig. 23, similar to the modifieation Figs. 16 and 17; Instead, however, of the arms I) b,1 provide the catch with pins gg,which are guided by holes in the rim, or vice versa, and the springs cl press upon the back of the catch at each end. The catch and supporting-rim are shown detached in Fig. 22.

The modification shown in Figs. 24 and 25, plan and front views, respectively, consists merely in widening or elongating the catch B, so that it has two holdinglips instead of one to catch upon the inside of the lid. Such a catch may be mounted in accordance with any of the modifications herein described, in which the arms b I) rest within a recess in the rim. The catches in the other modifications may also be provided with two holding-lipsinlike manner.

The modification shown in Figs. 26 and 27 is similar to that shown in Figs. 18 and 19; but instead of the arms sliding on the flange m the body of the catch is recessed on its back to fit said flange, as most clearly shown by the sectional view, Fig. 26,which shows the support ing rim and catch detached, the plane of sec tion being transversely through the middle of said parts. The springs can be attached as in Fig. 18, but made long enough to bear upon the body of the catch.

Figs. 28 and 29 are corresponding views ICC IIO

showing, practically, the same thing, but reversed, so that the flange m is on the inside of the rim 0 instead of the outside.

In the modification, Figs. 30 and 31, the rim is made of two parts secured together by screws or rivets, the inner part having a groove for the springs, as shown by the transverse section, Fig. 30. The detached plan views of the rim 0 and catch B in Fig. 31 show the slot or hole in the middle of the rim for the body of the catch to work in, and the guide-pins gg, secured rigidly to the catch and moving in holes through the rim, or vice versa.

In the modification, Figs. 32 and 33, I also form the supporting-rim O of two parts, but with both of them grooved, as shown by the transverse section, Fig. 33, in which the division is vertical. Fig. 34 shows a like view of the same kind of a rim, but divided horizontally instead of vertically. In such a rim the internal space is larger than in Fig. 30, so that there is room for the arms I) Z) of the catch and also for the spring j. The parts detached are shown in plan view in Fig. 82.

Another modification is shown in Figs. 35 and 36, the former showing the supportingrim and two parts of the catch in reverse plan, and the latter showing a transverse section on line x .r of Fig. 35 of said rim when in a corresponding position. lhe rim is recessed or grooved on its under side, the solid top being cutout, as indicated by broken lines at the middle of the rim 0, Fig. 35, to admit the body of the catch. Instead of making the arms I) I) integral with the body of the catch I form them of separate pieces and fasten them together by screws through the holes a. The under side of the latch and inner ends of the springs (Z (Z are covered and supported by the plate 0.

In Figs. 37 to 42, inclusive, I support the catch 13 on a stud, q, either on the rim, as in Figs. 37, 38, 39, and 40, or on the catch itself, as in Figs. 41 and 42, and corresponding holes in the catch or rim. I have shown these studs and their holes as square; but they may be of any other form, preferably angular or oblong. Such modifications may be made with rims recessed in different styles; but I have illustrated it as applied to rims in cross-section substantially like Fig. 3. Fig. 37 shows a detached front elevation of the catch B; Figs. 88 and 40, plan views of the rim with springs attached; Fig. 39, a rear elevation of the catch, middle portion of the rim, and attached springs; and Figs. 41 and 42 show plan views of the rim and catch detached from each other.

Fig. 43 shows the same construction as in Fig. 1, excepting that the supporting-rim and catch occupy a different position in the case, and that the push-pin a is rigidly connected with or formed on the catch 13. This arrangement is more especially adapted for the lid at the back of the watch case.

The modifications in Figs. 44:, 45, and 46 show catches which swing inwardly on apivot instead of sliding bodily. In all of them the supporting-rim G is of the form in cross-section shown in Fig. 3, and is represented as partly or wholly in horizontal section, with the catches in plan view. In all of them the catch rests upon and is supported by the lower flange of the rim 0, as is the construction first described.

In Fig. 44 the push-pin a acts upon one end of an intermediate lever s, the other end of which acts on the short end of the catch,there by forcing its longer end having the holding lip inwardly against the spring (Z.

In Fig. 45 the catch is in the form of a simple lever with the push-pin pressed directly against the body of the catch.

In Fig. 46 the push-pin acts against the intermcdiate levers, s, the same as in Fig.44,excepting that there are two levers and two catches.

Fig. 47 shows a plan and front view, respect ively, of a catch adapted for use with a rim like that shown in transverse section in Fig. 19, the flange at being notched in the middle to receive the body of the catch, while the notched arms I) Z) rest in the rabbets or recesses above and below said flange. Springs will be applied as before described. Such a catch is applicable to a rim having the flange at either on the outside or inside edge.

I claim as my invention 1. The combination of the supporting-rim O, recessed substantially as described, the catch having arms I) b resting in the recess of said rim, and the spring or springs for pressing against the catch, suhstantiall y as described, and for the purpose specified.

2. The combination of a watch-case, the sup porting-rim, the springpressed catch mounted therein, and the dust-band secured to the re spective ends of said rim, substantially as de scribed, and for the purpose specified.

3. The combination of the supportingrim stationarily affixed in a watch-case, the catch moving inwardly and outwardly and supported in said movement by said rim, and the spring or springs for pressing against said catcli,sub stantially as described, and for the purpose specified.

4. The combination of the supporting-rim having lateral flanges forming a groove or recess at the outer edge of said rim, the catch having its body working in a notch in the upper flange of said rim, and the arms 0 1), working within the groove on each side of said notch, substantially as described, and for the purpose specified.
