WATCH REGU LATO R.

SPECIFICATION forming part of Letters Patent No. 355.093, dated December28, 1886. Application filed August 19, 1885. Serial No. 174.788. (No model.) Patented in France October 17?, 1e84, No. 164,879.

To aZZ whom it may concern.-

Be it known that I, J ULns CHARLES Lnvlis- SEUR, of Milianah, Algeria, have invented a new and Improved lVatch Regulator, (for which I have received Letters Patent of France, No. 16%,879, dated October 13, 1884-,) of which the following is a full, clear, and exact descrip tion.

The object of my invention is to provide means for adjusting the balance-regulator of a watch without opening the case.

The invention consists of a segmental'gear' wheel attached to or formed upon the regulator,and mechanism in gear therewith, whereby the regulator maybe adjusted by means of the winding-stem when arranged for setting the hands, or by an independent stem fitted in the case; also, in the combination therewith of an index or tell-tale visible on. the dial to indicate the position of the regulator; and, finally, in the construction and combination of parts, as hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a face view of a stem-winding watch to which my improvement has been applied. Fig. 2 is a rear view of the same, parts being broken away to reveal the construction. Fig. 3 is an edge View of the same, partly in section, on the broken line a" :r, Fig. 2. Fig. 4 is a front View, the case and dial being partly broken away to disclose the arrangement of parts; and Fig. 5 is a rear view of a keywinder, the case being partly broken away to show the application of the improvement.

In the case A of the stern-winder is mounted the usual winding-stem, B, connected with the mainspring mechanism,and adapted to be disconnected from the same and geared with the hand-setting mechanism by means of the usual push-button, 0, all in the ordinary manner.

On the arbor D of the minute-hand is fixed the pulley E, around which is passed an endless chain, F, which also passes loosely around a pulley, G, mounted on an arbor, H, on which. is also mounted a spur-wheel, l. The spurwheel I engages with a pinion, J, mounted on a spindle, J, on which is also mounted a second pinion, K, which engages with a segmental gear-wheel, L, attached to or formed upon the l regulator L. The latter is of the ordinary description for adjusting the tension of thehairspring acting on the balance-wheel.

The pinion J on the spindle J is in gear with a segmental rack or gear wheel, M, fixed upon a spindle, M, mounted in suitable bearings in the casing of the works. The forward end of the spindle M projects through the dial and carries a pointer or index, M, which registers with the divisions of a se mental scale, M, on the face of the dial. The index M thus turns with the regulator and serves to indicate the position of the same, the scale M being marked in the usual manner to indicate the direction and distance the regulator is to be turned to make the watch run slower or faster. With the pinion K, with which the rack L is in gear, also engages a crown-wh eel, N,mounted on the inner end of a stem, N, turning in suitable hearings in the works and having its outer en (1 ing through the rim of the case A.

To the inner end of the sliding head N is attached the free end of a hat spring, 0, fixedin the casing, which spring tends to hold the head in its outer position projecting from the easing, so as to be capable of easy adjustment by the fingers. The spring 0 is pressed inward, to withdraw the head N within the casing, by a button or push-piece, P, mounted to slide on the rim of the case, and provided on its inner part with a cam-piece, P, which, when operated, acts upon the flat spring 0 to retract the head N the button P sliding over the end of and concealing the same.

Adjacent to the endless chain F is pivoted an angle-lever, Q, the outer arm of which projects through the rim of the case and carries a sliding button or push-piece, Q.

Theinner arm of the lever Qis made springy, and carries a small rotary disk or pulley, Q, adapted to be pressed against and tighten the endless chain F when operated by the button Q, thus causing the spur-wheel I, in gear with the regulator, to turn coincident-1y with the minute-hand arbor when the hands are being adjusted by means of the winding stem In Fig. 5 I have illustrated a key-winding watch to which my device has been applied, the arrangement of the independent adj ustingstem N and its crown-wheel Nbeing the same squared to receive a sliding head,l l projectas in the stem-winder, except that the sliding head N is omitted and the stem squared to re ceivethe l;ey-shanl or such head may be used, if desired. The stem, when not in use, is con cealed by the sliding button 1?.

If preferred, the regulator may also be connected with the hand-arbor, as in the stenr winder, and in the same manner.

The operation is as follows: To adjust the regulator without disturbing the hands, the sliding button P is pushed back to allow the head N of the stem Ix" to be projected from the rim of the case by the spring 0, and the stem N is then rotated by its head to turn the segmental rack on the lQglllfltOF-SPllltllG to the proper position, as indicated by the index on the dialiace. To adjust the regulator when the hands are being set forward or backward, and thus make the watch run taster or slower, respectirely, the puslrbutton C operated to disengage the winding mechanism and throw the hand'arbor in gear with the stem 13, in the usual manner. The button (,1 is also moved to tighten the endless chain and connect the 1ninute-hand arbor with the regulator, as before stated, so that when the minutehand is turned the regulator is adjusted simultaneously therewith, and the error and rate of the watch are compensated for coineidently. The chain 1*, when free from its tension-disk, is slack, and the hands can then be set in the usual manner without disturbing the regulator.

Having thus fully described my invention, Iclaim as new and desire to secure by Letters Patenty 1. In a watch, the combination, with the hand-arbor niechanisi'n and the balance-regulator, of gearing connecting the regulator with .gear with the latter pinion, and an index or pointer turned by the latter rack and registering with a scale on the watch-dial, snbstan tial'ly as shown and described.

3. In a watch, the combination, with the case and the balance-regulator, of an exteri- Orly-adj ustiable stem connected with the same, a sliding operating-head on the stem, a spring connected with the sliding head, and a sliding button acting on the spring and arranged to cover the head, substantially as shown and described.

l. In a watch, the combination, with the case, the balance-regulator, and the minute hand arbor, of gearing connecting the same with the regulator, pulleys, and an endless chain or belt interposed in said gearing, and a pivoted lever carrying a friction-disk for tightening the belt and prorided with a push piece for operating it, substantially as shown and described. I
