STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 414,697, dated November 12, 1889.

Application filed July 10, 1889.

To all whom ifmay concern:

Be it known that I, ISAAC GODDARD, of Richmond, in the county of Henrico and State of Virginia, have invented new and use- 5 f ul Improvements in Watches; and Ido hereby declare the following to be a full, clear, and exact' description of the same, reference being had to the accompanying drawings, forming a part of this specification,and to the figures and letters of reference marked thereon.

In the accompanying drawings, Figure l is a front elevation of a portion of a watch of the Elgin pattern, showing the application of my improvement. Fig. 2 is a transverse section on line w in Fig. 1. Fig. 3 is a detail view of a part of the plate and the pinionshifting spring. Fig. at is a side elevation with the plate removed, showing the lever for stopping the scape-wheel and second-hand. Fig. 5 is a front elevation of a watch with the dial removed, showing amodified form of my improvement; and Fig. 6 is a view of the inside of the front plate of the same, showing the stopping-lever. Fig. 7 is a plan View of a \Valtham watchmovement to which a modification of my improvement has been applied. Figs. 8 and 9 are transverse sections taken on line as a: in Fig. 7, showing the stop in two positions. Fig. 10 is a plan view of a \Valtham movement provided with a slightly different form of the invention. Figs. 11 and 12 are transverse sections taken on line 1 y in Fig. 10, showing the stopping device in different positions; and Figs. 13 and 14c are transverse sections showing further modifications of the invention.

Similar letters of reference indicate corresponding parts in all of the views.

Although the better grades of watches are constructed to run very uniformly, it is well known that the majority of watches, even of the best construction, will gain or lose time to a greater or less extent, according to their perfection and according, to the manner in which they are used; and, while in many kinds of business (especially in railroading) exact time is absolutely essential, it is not practicable for an ordinary watchwearer to make allowances or computations each day to ascertain the exact standard time. It is therefore recognized as the sim- Serial No. 317,017. (No model.)

plest and safest way to have the watch set periodically by a reliable standard time.

Recent improvements in the construction .of watches provide for winding and setting through the case-pendant, and even the lever formerly used in stem-winding watches to disengage the winding mechanism and engage the hand-setting has been dispensed with. This form of movement construction has allowed the use of cases made in such a way as to render them more thoroughly dustproof than cases of ordinary construction; but the construction by which the advantage of tightness is secured has of necessity made it more difficult to gain access to the secondhand of the watch for the purpose of accurate setting.

To obviate this disadvantage and to provide a simple, safe, and reliable means of setting watches to the exact second without requiring immediate access to the second-hand is the object of my present invention, which consists in the use of devices for instantly stopping the movement of the train of the watch and also of setting the hands at the desired point and then starting the watch at the instant desired, the mechanism consisting in a lever arranged to be operated by the winding-stem and carrying a delicate brake for engagement with the scape wheel or pinion or any other movable portion of the train; also, in the combination, with the said lever, of devices for throwing the winding mechanism out of gear and throwing the hand-setting S5 mechanism into the position of use, these devices of course being varied to conform to the form and construction of the particular watch to which the movement is applied.

The winding-stem A is provided with a stop, which permits of its being withdrawn a short distance.

To the inner surface of the upper plate of the watch is pivoted alever B, the arm a of which rests against the inner end of the wind- 9 5 ing-stem A, and the arm I) of which carries a delicate spring 0 for engagment with the scape-wheel d, and the arm 6 of which serves as a stop.

In a cavity in the outer face of the upper 10o plate are arranged the usual dial-wheels fg, also the wheels h t', which communicate with the wheel j upon the barrel-arbork, and upon a stud l in a cavity m of the upper plate is placed a spur-pinion a, which is capable of engaging one of the wheels 9 71-. The pinion 72 carries a cone 0, which is engaged by a le ver 1), pivoted on the screw q, the said pinion being pressed upward by a springr. The lever 19 is provided with a studs, which extends through the plate and is engaged by the lever arm I), and spring 2, connected to the upper plate, bears upon a shoulder of said lever 19. A yoke u, arranged to turn up a pivot concentric with the wheel 71, carries the wheel '1', the said yoke being normally held in such a posi tion as to cause the engagement of wheels t' and j by means of a spring r, secured to the upper plate, and when in this position the opposite end of the lever 10 is in engagement with the end of lever 19, which projects over the pinion n. In the under surface of the lever 19 is formed a conical cavity adapted to engage the cone 0, carried by the pinion 11. Normally the stem A is pushed in, thereby turning the lever 19 out of engagement with the yoke u and bringing the wall of the eoni cal cavity in the said lever p into engagement with the cone 0 on the pinion n,thereby pushing down the said pinion, so as to disengage it from the wheel g. By turning the stem A while the wheel h is in engagement with the beveled pinion w on the said stem the spring in the barrel is wound through the medium of the wheels 72 \Vhen it is desired to set the hands, the stem A is pulled out, thereby allowing the spring 0 to come into contact with the scapewheel cl, balance, escapement, or any portion of the train, at the same time liberating the lever 17, so that it allows the spring r to press the pinion n upward into engagement with the wheel g, at the same time turning the yoke 16 so as to disengage the wheel i from the wheel j, when the hour and minute hands may be turned, while the second-hand is held still by the engagement of the spring 0 with the scape-wheel (7, balance, escapement, or any portion of train.

111 the modification shown in Figs. 5 and t5 the yoke u is arranged to turn on a pivot concentric with the wheel 71 and the said yoke is provided with three arms a a '20, the arm a carrying the wheel 1', which meshes into the wheel 71 and engages the wheel j on the winding-arbor, and the arm a carrying the pinion a, which meshes into the wheel 7:, and the wheel g, which is engaged by the pinion n. The arm a" is pressed by a curved spring '0, which tends to throw the wheel 1' into engagement with the wheel j and to hold the wheel g out of engagement with the wheel f on the minute-hand arborf." Upon the extremity of the arm n, is formed a cam a, which is engaged by a finger I), carried by the lever B, pivoted to the front plate and provided with a curved arm h, which extends through the rim of the watch and is provided with a thumb-piece t". On the inner surface of the plate is pivoted a springbrake-lever c, which is capable of engaging the periphery of one of the wheels or pinions, escapement, or balance of the trainthe fourth wheel (Z, for example. The longer arm of the lever c, which contacts with the wheel, is made so light as to prevent it from injuring the gearing, and the opposite end is slotted to receive a pin .9, which projects from the lever B through the front plate of the watch-movement. The wheel h is engaged by a pinion w on the winding-stem A, as in the other case, so that whenever the stem is turned the said wheel will also be turned. It the stem be turned while the lever 3 is pushed in and the wheel I: is in engagement with the wheel j, the mainspring will be wound. \Vhen the lever 13 is pulled out, the engagement of the cam a on the end of the arm to by the finger I), carried by the said lever, will turn the yoke a on its pivot, thereby disengaging the wheel 2 from the wheel j and bringing the wheel g into engagement with the wheel f on the minute-hand arborf. Just before the wheel g is brought into engagement with the wheel f the leverc' is pressed against the wheel (1, thereby stopping the watch with the second-hand in the desired position. The watch may now be set in the manner before described, after which the lever Z) will be pushed in, releasing the wheel d and throwing the wheel i again into engagement with the wheel j, so that thewatch is in condition for winding. The lever c in either of the forms we have described may be arranged to touch any suitable \vheelpinion of the move ment or any other suitable moving part, as the eseapement or balance.

In the modification shown in Figs. 7 to 9, inclusive, an angled spring-arm B is secured to the inner surface of the upper plate of the watch-movement, as shown in dotted lines in Fig. '7. The free extremity of the angled arm is furnished with a conical bearing-point 0, which projects through the plate and is ca pable of touching the under rim of the bal ance, the spring-arm being arranged to hold the point C normally away from the balance, as shown in Fig. 8. To the angle of the arm is secured a stud D, which projects downward into the space between the back and front plates of the watch into the path of the setting-stem E. The said setting-stem E is provided with a flange F, which rests upon a spring Gr, held in a recess of the lower plate. The point C is preferably made of yielding material, so that when it is pushed forward against the balance it can be done no injury. \Vhen the stem E is drawn out, throwing the setting mechanism into position for setting the hands, the spring-arm asserts itself, and the point C is brought into contact with the under rim of the balance-wheel, as shown in Fig. 9.

In the modifications, Figs. 1.0 to 12, inclusive, the construction is the same as that already described, with the exception of the substitution of the delicate curved spring 0' for the point C, and in Figs. 13 and 14 the construction is similar to that shown in Figs. 10 to 12, inclusive, the only difference being that the spring C is reversed on the springarm 13 I do not restrict myself to the precise forms of construction shown and described, as it is evident that watch-movements of different forms of construction will require modifications in the application of my device, and which can be done without departing from the spirit of my invention.

Having thus described my invention, whatI claim as new is- 1. In a watch-setting mechanism, the combination, with the hand-setting mechanism, of a brake operated thereby to arrest the movement of the train while the hands are being set, substantially as described.

2. In a watch-setting mechanism, the combination, with the dial-wheels and Windinggear, of the Winding-stem, a shifting-gear and mechanism engaging therewith for moving said gearing into engagement with the winding-gear or dial-wheels, respectively, and a brake operated thereby for arresting the movement of the train while the gear is in engagement with the dial-wheels, substantially as described.

3. In a watch-setting mechanism, the combination, with the winding-stem and. dialwheels and gearing between said stem and wheels for setting the hands, of a brake moved by the winding-stem for arresting the movement of the train while the hands are being set, substantially as described.

4. In a watch-setting mechanism, the combination, with the longitudinallymovable winding-stem, dial-wheels, and winding-gear, of a shifting-gear gearing with and moved by the winding-stem into engagement with the dial-wheels or winding-gear, respectively, and a brake moved by said stem for arresting the movement of the train while the stem is in engagement with the dial-wheels, substantially as and for the purpose set forth.

5. In a watch-setting mechanism, the co1nbination, with the dial-wheels, train-wl'leels, winding-stem, and gearing adapted to communicate motion from the winding-stein to the mainspring-arbor and t0 the dial-wheels, of a yielding brake-lever arranged to contact with one of the wheels of the train, substantially as specified.

6. In a watch-setting mechanism, the combination, with the dial-wheels, train-wheels, winding-stem, and gearing adapted to communicate motion from the winding-stem to the mainspring and to the dial-wheels, of a yielding brake lever arranged to contact with one of the moving parts of the movement when the winding-stem is engaged with the hand setting mechanism, sbstantially as shown and described.

7. In a watch-setting mechanism, the combination, with the hand-setting mechanism, of a yielding brake-lever moved thereby for stopping the movement of the train when the hand-setting mechanism is operative, substantially as described.
