JEAN J. L. BRUN, OF HIGHLAND, ILLINOIS, ASSIGNOE OF ONE-HALF TO TIMOTHY GRUAZ,

OF SAME PLACE.

SELF-WINDING WATCH.

SPECIFICATION forming part of Letters Patent No. 271,030, dated January 23, 1683.

(No model.)

10 all whom at may concern Boit known that I, JEAN JAQUES Louis BRUN, a citizen of the United States, residing at Highland, in the county of Madison and State oflllinois, have invented certain new and useful Improvements in Self-Winding \Vatches; and I do 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 accompanyingdrawings, and

to the letters and figures of reference marked thereon, which form a part of thisspecification.

This invention relates to improvements in watches, and is self or automatically winding, and is adapted to indicate the length of time for which it is wound up, and to arrest the action of the winding mechanism at the proper time; and the nature of the invention consists in the employment of a vibrating weighted lever actuating a ratchet, pawls, and pinion gearing with a pinion on the mainspriug-axis, said lever beingsuspendedin position by means of a spring, while at points at the ends of its strokes are arranged spring rolls or cushions.

ltoonsists,also,ofatoothed segment-orquad' rant, engaging with a pinion on the mainspring-axis, and carrying an index or pointer registering with a graduated are on the watch face or dial.

It consists, further, in the employment of a two-armed plate or lever, suitably hung or pivoted in position, with one arm adapted to bear on a nut riding upon a screw-thread of the mainspring-axis, and the other arm to arrest the movement of the aforesaid lever after the winding up of the watch,substantially as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a face view of a watch-dial embodying my improvement in part, and Fig. 2 is a view of the inner disk or plate of a watch or its frame with the remaining parts of my invention applied thereto. Figs. 3 to 9 are detail views of my invention.

In carrying out my invention, I employ a lever, A, pivoted at one end upon an axis or pivot, a, supported in the disk or plate B of the watch-frame, and a bracket, b, secured to an additional piece of the watch-frame. Said end of the lever is secured to one end of a strong, powerful spring, 0, the opposite end of I which is fastened to the watch frame disk or tion. The spring G has a series of apertures in one end to enable the taking up the slack or regulating the tension. The lever A is also fastened at the same end to a ratchet, D, with which engage pawls d d, hung upon the inner circumference of an annular flange of a large -pinion,I l, said ratchetand pinion turning upon the axis or pivot a of the lever A. The wheel or pinion E is adapted to gear with a pinion, E,on the mainspring-axis 6, whereby its movement, received through the ratchet and pawls fronrthe lever, the operation of which will be presently described, is transmitted to and causes the winding up of the mainspring. The opposite end of the lever A has affixed to it a weight, A, to impart momentum thereto in its suspended position, and, held under the action of the spring 0, as the watch, with the lever, is carried in the pocket, partakesofthevibrations of the body of the carrier, whereby the operation of winding up the mainspring ot'the watch will be eflected automatically. The weightis prevented from striking the watch-case, and concussion thereof overcome by disposing frictional rolls A at the two extremes or points limiting the movement of the weight, said rolls being hung or having their bearings in the bifurcated ends of curved springs A, fastened to the disk 13 of the watch case or frame. The lever A has also at the latter end a frictional roll, a, which travels between and against the disk B, and a raised rail or bar, A, fastened to the said disk at its ends, and which prevents lateral or side movement of the lever.

The mainspriug F (seen in Fi 8) is incl'osed within a circular case, F, secured to the disk or plate B, while its axis 0 turns in a suitable bearing-plate fastened to the disk and in a bracket, 0, said axis being screw-threaded and carrying a nut, F The axis 0 extends a short distance beyond theinclosing-caseofthe spring its nut during winding and unwinding of the spring, the purpose of which will be seen directly. On the end of the axis 0 next to the dial is a small pinion,f, (see Fig. 3,) which engages with a toothed segment or quadrant, G, suitably hung or pivoted in position upon the plate B, and carrying upon its pivot, which projects through the dial, an index or pointer,

plate at c, which holds it in a suspended posi-' F, to permit the required movement thereon of II. This index or pointer registers with a graduated arc, I, on the dial, as seen in Fi 1, its graduation indicating, in the presentinstance, sixty (60) hours divided up into intervals of ten hours. It will be therefore seen that when the maiuspring or the watch is wound up the quadrant G will travel in one direction as the pinion f, with which it gears, is turned by such winding-up action of the spring, and thus cause its pointer or indicator H to move and register on the graduated are I on the watch-dial with the number indicative of the length of time for which the watch is wound up. Upon the unwinding of the spring or the running down of the watch it will of course follow that the movement of the pin- -ionfwill he reversed, and the quadrant will move in the opposite direction, carrying its pointer back to the starting-point, when it will be ready to'be again carried forward, as before.

J J are two arms,fastened toor formed with a connecting-piece at their upper ends, which is hinged or pivoted to the disk B, to enable the arms to swing outward therefrom at their lower ends. One arm, J, is curved inward, and bears against and enters a recess in the end of the nut F of the mainspring-axis c, said nut being prevented from turning, as it rides ontward and inward, upon said axis by a guidepin, 9, fixed to the case F, and projecting through an aperture or slot in said nut. The other arm, J, has a tooth, h, at its lower end, which engages with a series of teeth, h, on the inner surface ofa slightly-curved vertical crossbar, K, of the lever A.

It will be noticed that when the mainspring or watch has been wound up, at which time the nut F will have l'aveled to the outer end ot'its screw oraxis, as before explained, the arm J, bearing-against said nut, will be carried outward by the movement of the nut, which will cause its fellow arm J to have like movement and bring its tooth into engagement with the coincidentnotch between two of the teeth of the bar K of the lever A, and thus arrest further action or movement of the lever, and consequently stop the winding operation. By means of this invention an automatically or self winding watch is obtained, and one whereby also thelength of time for which it is wound up isindicated and the winding-up operation or tightening of the maiuspring is arrested at the proper moment. v

Having thus fully described my invention, 1 claim and desire to secure by Letters Patent of the United States- 1. In a 'atch, the combination, with the mainspring and its screw-threaded axis carry- 2. In a watch, the combination, with the mainspring having a screw-threaded axis carrying a nut, of the spring, pendulum-lever operating mechanism adapted to wind up or tighten the said spring, the toothed quadrant or curved rack gearing with a pinion on the maiuspring-axis and carrying a pointer or index, and the hinged or pivoted arms, one bearing against the mainspring-axis nut and the other adapted to arrest the movement of the pendulum, substantially as and for the purpose set forth.
