UNITED STATES PATENT @Erica CHARLES E. JAGOT, 0F CHAUX-DE-FONDS, SVITZERLAND, ASSIGNOR TO SALTZMAN, JACOT & CO.

IMPROVEMENT lN .WINDING AND SETTING-WATCHES.

Specification forming part of Letters Patent No. 114.4193, dated September 27, 1864.

To a/ZZ whom it 71mg concern:

Be it known that I, CHARLES E. Jnoo'r, a citizen of the United States, residing in ChauX-de-Fonds, Switzerland, have invented, made, and applied to use a certain new and Improved Means for Winding and Setting Watches; and I do hereby decla-re the follow` ing to be a full, clear, and exact description of the said invention, reference being had to the annexed drawings, making part of this specification, wherein- Figure l represents my improvement as complete on the plates of a watch. Fig. 2 is a section at the winding-stem. Fig. 3 is a plan, and Fig. 4 is a side view, of the swinging plate carrying the intermediate wheels.

Similar marks of reference denote the same parts.

The nature of my said invention consists in an arrangement of gearing, actuated by a stem or winder passing to the outside of the case, said parts being applied in such a manner that the stem can be employed for winding the watch or for setting the hands, and in case the stem is turned in the wrong direction it is inoperative, as the turning motion separates the gears, and in setting the hands the spring is not wound up, neither are the hands moved by the act of winding' the spring. The mechanism for effecting these opera-tions is complete in itself, and does not have to be removed in taking the works out of the case or in replacing the same, as the stem is movable and is to be introduced in its place after the works are putin the case.

In the drawings, c is the main plate of the watch. b is a secondary plate or rim, and c is the arbor-plate or upper plate of the works. d is the spring-barrel, with the pawl o, taking the teeth of the wheel e, which wheel e is affixed to the arbor of the spring-barrel d. fis a wheel on the arbor of the minute-hand. The other wheels, pinions, balance, arbors, dre., comprising the watch-movement itself, may be of any desired character, as the same does not form any part of my said invention.

On the plate c is a stud, t', securely attixed and sustained at its upper end in the plate c. Upon this stud i is a miter-wheel, li, that is formed with a circular hub passing through a corresponding hole in the swinging gear earlier-plate 7c, and Z is a gearwheel secured to L by screws atl 1, so that the two (l and 7i) move together, and the said plate kis between them. This plate k is formed with two gudgeons, Zand 3, (see Fig. 4,) upon which are placed the intermediate wheels, m and n., and secured by screws passing into said gudgeons. This plate L' is pressed by the spring p, (see dotted lines, Fig. 1,) so that the wheels n and e remain geared together but if the pushing-pin q is pressed upon, the wheels n and e are thrown out of gear, and the wheel m comes into gear with the wheel as, that is sustained by a screw or pin on the plate c, and is in gear with the wheelfon the arbor ofthe hands. This pushing-pin q is retained in place, but allowed a certain amount of end motion by the small screwthat takes between the shoulders formed by a flattened space on said rod, as seen at et.

1' is a miter-gear formed with a hub on each side of the gear, which hub is conned by and turns in bearings formed in the plate c and a block, s, which block and plate are both inortised or slotted to allow themiter-gear to turn freely. The hub or arbor of this unter-ger.L is formed with a square or polygonal hole, receiving the end of the stem t, which end is of acorrespondin g polygonal shape, and a groove turned in said stem at yu receives the point of a screw, so that said stein is free to turn, but cannot be withdrawn, except after the screw has been removed.

It will now be seen that the works of the .wa-tch, including this winding apparatus, can

be introduced in the ease without the stem, and then said stem be entered through a hole in said case into the unter-wheel r, and there retained by the screw in the groove u.

It will now be understood that when the hands are to be set the pin q is to be pushed in, which connects the gearing from the stein with the hands and disconnects the windingwheels. Ordinarily the winding-wheels remain in gear; but there is no motion to either ot' them, except when winding the watch. Therefore there is nothing to interfere with the correct movement of the watch, and in case the shank is turned in the wrong direction the teeth of the wheels will not be injured, but the wheel n, tending in that case to turn the wheel e against the pawl o, cannot turn it in that direction, but the power rolls the wheel n out toward the edge of the watch, because the plate 7c, with these two wheels m and n, swings on the stud i as its center against the action of the spring p, and the teeth of n and e separate. This motion, however, is not sufficient to cause the wheels m and x to gear together.

What I claim, and desire to secure by Letters Patent, is-

l.v The mitm-gears IL and r and shank t, applied as speeilied, in combination with the wheels laudn, acting upon the wheel e, to wind the spring, as set forth.

2. In combination with the foregoing, the swinging plate 7c and gear m, to operate on the hands when desired, as set forth.

In witness whereof I have hereunto set my signature this 5th day of July, 1864.

CHASE. JAGOT.
