ADOLPI-IUS J. LUSTIG, OF NElVARII, NEW JERSEY.
WATCH-C ASE SPRING.
SPECIFICATION forming part of Letters Patent No. 466,527, dated January 5, 1892. Application filed March 17,1891. Serial No. 385,413. (No model.)
To all whom it may concern:
Be it known that I, ADOLPHUS J. LUSTIG, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Watch-Case Springs; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.
The present invention, set forth in detail hereinafter, relates to improvements in watchcase springs, the invention being designed to provide a simple and easy means for securing the case-spring within the Watch-spring.
The invention is illustrated in the accompanying sheet of drawings, in which similar letters of reference are employed to indicate corresponding parts in each of the several views.
In said views, Figure 1 is a vertical section of a watch-case with my improved spring attached, clearly illustrating the manner of securing the spring in position by means of a saddle or block. Fig. 2 is a front elevation of the spring, and Fig. 3 is a top view of the same, the saddle or block being indicated in dotted lines. Figs. 4 and 5 are a front view and plan of a slightly-modified form of spring, and Fig. 6 is a view similar to that shown in Fig. 1, illustrating the manner of securing the spring shown in Figs. 4 and 5 within the watch-case. Figs. 7 and 8 are views similar fied form of securing the watch-spring in which the use of the saddle or block is entirely dispensed with.
In the drawings, Aindicates the watch-case, which is of any ordinary construction.
a is my improved spring, bent to conform with the contour of the watch-case and provided with a centrally arranged recess or cutaway portion a, and provided with the usual tongue a adapted to press against the lid or cover of the case and operate the same in the usual manner. The spring is secured within the case by means of a saddle or block 1), provided with a slot 1), into which the spring a .away or recessed portion is fitted, so that said saddle 12 projects down on opposite sides of the spring, the edges a and a of the recess a preventing the displacement of the spring when in position in the slot in the saddle. Said saddle or block is provided with a threaded hole 13 and by means of a screw 0 I secure said saddle or block to the casing, as clearly shown in Fig. l, and hence the spring is properly held in its position and successfully operates the lid or cover of the watch-case.
In Figs. 4:, 5, andG I have illustrateda modified form of construction in which Ibend that portion of the spring directly beneath the recess a backwardly at a into which the saddle or block b may be fitted, as clearly shown in said Figs. -5 and 6. In this case I avoid the use of a slot in the saddle, which is secured within the case by means of the screw 0 in the same manner as has just been described.
My improved Watch-case spring is also provided on its under side with a second cuta whereby the much narrower at its middle than at its immediate connecting portions. This is of great advantage in the form of spring provided with a backwardly-bent portion of, which must project upon the narrow space or rim of the watch-case center, as willbe evi= dent.
Instead of securing the spring shown in Figs. 4 and 5 in the above-described manner, I can entirely dispense with the use of the saddle b. As illustrated in Figs. 7 and 8, the pin or screw 0 is made to enter in front of the depression a in the spring, which causes the latter to be held in position in the case between said screw and the inner surface of the watch-case, as will be evident from Fig. 8.
Heretofore it has been the practice to provide the steel springs in their edges'with a threaded perforation, into which the screw 0 is fitted to secure the spring within the case. This has been difficult to make, and in tempering the spring the threaded perforation would very often become damaged. In my present invention there are no holes in the spring, such holes being made in the saddle, which in this case can be made from soft metal and hence more readily drilled. Thus spring is I have devised a very cheap and sure means for securing the spring within a watch-case, whereby the spring action of the tongue end readily forces open the lid or cover when the crown of the Watch-case has been depressed.
From Figs. 2 and 4 it will be seen that the spring is provided with the cut-away portions a and (1. which are essential in enabling the steel spring to be bent into the proper curve, whereby said springis caused to conveniently rest above the movement of the watch.
Having thus described my invention, what I claim is- 1. AWatch-case spring provided with a backwardly-bent portion, in combination with a saddle or block adapted to lit in said backwardly-bent portion, a threaded perforation in said saddle or block, and a screw for securing said saddle or block to the watch-case, substantially as set forth.
2. A watch-case spring bent to conform with the contour of the watch-case and consisting of an arc-shaped spring having a tongue at one end and a centrally-disposed recessed portion a and bent baekwardly, as at a toward the rim of the watch-ease, as set forth.
3. The combination, with a Watch-case, of a spring having a tongue at one end and a centrally-disposed recessed portion bent backwardly, as at a, toward the inner face of the rim of the watch-case, and means for securing said spring in position, substantially as and for the purposes set forth.
A. A watch-case provided with abackwar ly-bent portion extending toward the inner face of the rim of the watch-ease, bent at a right angle, or approximately so, substantially as set forth.
5. A watch-case spring consisting of an areshaped spring having a tongue atone end and oppositely and centrally disposed recessed portions to and a and bent backwardly, as at (0, whereby said portion is adapted to project into the narrow portion of the watch-case center, as and for the purposes set forth.
6. A watch-case spring provided with a back- Wardly-extending bend at some point in its length, said bend being greatly reduced in width as compared with the width of the spring, as and for the purposes set forth.
In testimony that I claim the invention set foith aboveI have hereunto set my hand this 7th day of March, 1891.
