SPECIFICATION forming part of Letters Patent No. 289,352, dated November 27, 1883.

7 Application filed May 15, 1883. (Model.)

To all whom it may concern-.-

Be it known that I, EDMOND KUHN, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Watches, of which the following is a specification, reference being had to the ac companying drawings, in which- Figure 1 represents a face view of my improved watch. Fig. 2 is a face view of the same after the dial-plate and hands have been removed. Fig. 3 is a back view of the watch, showing the wheel for turning the springbarrel. Fig. 4 is a cross-section of the watch, the line of section being indicated at c c in I5 Fig. 2. Fig. 5 is a sectional view through the stem and spring-barrel on the linekk,

Fig. 3. Fig. 6 is a perspective view of the ring that supports the dial-plate.

This invention relates to improvements in stenrwinding watches, and has for its object to make such watches as inexpensive and simple in construction as possible.

The'invention consists in the employment of a certain ring having feet thereon for the purpose of supporting the dial-plate, all;as hereinafter more fully described.

In the accompanying drawings, the letter \V represents the watch-case, of suitable e011- struction, but with a recess in its inner side for receiving the wheel I).

S is the stern of the watch, swiveled so that it can be readily turned. This swiveled stem S carries at its inner end a toothed wheel or crown-wheel, Z), whichfis contained in the recess of the watch-case, as shownin Fig. 3, and gears directly into the toothed wheel A, that is mounted upon the spindle (Z of the drum B, that contains the mainspring, so that by turning the stem S the mainspring can be wound up, the wheels I) and A always being in gear with one another. A pawl, c, to prevent the wheel A turning backward, enters between its teeth, as shown in Fig. 8, but does not interfere with the proper winding motion of the said wheel. The train of wheels of the watch contains, also, a wheel, C, which fis mounted upon the spindle into which the geanwheel carried by the drum B meshes, which wheel Gjtransmits motion by a pinion, 50 f, which it carries to the toothed wheel 9, that carries the tubular projection h, 'upon which the hour-hand i is mounted. Through the tube h projects the spindle that carries the minutehand j, said spindle being mounted upon a toothed wheel, I, which meshes directly into the teeth of the wheel 0. The wheel G and its pinion f are frictionally fitted upon their spindlethat is to say, they are carried by frictional contact by said spindle which receives its rotation by other means from the mainspring, and are capable of revolving independent of or on said spindle whenever it is desired to set the hands. To this end a sliding rod, D, is fitted through the wateh-case \V, as shown in Fig. 2, and carries at or near its inner end a toothed wheel, m. Aspring, a, bearing against a fixed plate, 0, at its inner end, and against a shoulder of the sliding rod D, at its outer end, serves normally to keep the wheel in out of contact and away from the wheel C; but when it is desired to set the hands, the slide D is pushed inward until the wheels at and G gear into each other. as indicated by dotted lines in Fig. 4, and thereupon, by simply turning the slide D with the end of the finger that presses it inward, the wheel 0 will also be turned and with it the wheels and I. and the hands will be set, as desired. \Vhen pressure is taken off the slide D, the spring a at once throws the wheel m out of gear. The wheels 9 and Z and their respective tubular and solid spindles are united to the dial-plate E, which usually is made of paper. This dial E rests on a ring, F, which shown more clearly in Fig. 6, which ring has projecting feet a, that rest on the back of the bottom plate, G, of the watch-case. The feet a hold the dial plate E far enough from the plate G to leave room for the wheels and Z andf and G, as indicated in Fig. 4-. By setting the wheel 1) into the recess of the watchcase, room for placing the drum B nearer the edge of the watch is obtained, and an inner support for the stem S made unnecessary.

I claim- The combination of a watch case having plate G, with the detachable ring F, having feet a, and with the dial-plate E, resting on said ring, and with the wheels g I, substantially as and for the purpose specified.
