Be it known that I, ARTHUR JUNGHANS, watchn1anufacturer, of Schramberg,Kingdom of Viirtemberg, Germany, have invented certain new and useful Improvements in Watches, of which the following is a specification.

My invention consists of a watch mechanism having the following advantages: first, possibility of providingthe watch with a very strong mainspring; second, easily working winding-up mechanismin spite of the extraer dinary strength of the mainspring, in combination with a mechanism for setting the hands by the pendant; third, strong toothed wheels and a cheap escapement can be employed which work with the utmost precision,notwithstanding their nish and cost.

In the accompanying drawings, Figure l shows the winding-up mechanism as it may be seen on the movement when thelatter is taken out of its case. Fig. 2 shows the barrel and the mainspring after removing the windingup mechanism. Fig. Sis a section through x y of Fig. 1. Fig. 4 is a view ofthe work after removing the plate B. Fig. 5 shows the wheels placed under the dial. Figs. 6, 7, and Sshow separately the pieces which compose the watch-case and the winding-up ring. Fig. 9 is a longitudinal section through the case, and Fig. l() is a cross-section of the same.

In all the figures similar letters refer to similar pieces.

. The movementis between two plates, A and B, which are connected together by four pillars, b. The works are held within the case M either by means of three projections, c, formed upon the periphery of plate A, resting upon flanges s of the case M, or in any usual manner employed for fastening the movements into watch-cases. On the center of plate B there is affixed a pillar, C, which becomes the pivot for the barrel-wheel D, the ratchet-wheel E, and the winding-up lever F,

Fig. 1.

The barrel D is composed of a large gearwheel having ve pins, d. The outer end of the mainspring G is affixed to one ot those pins. The other pins are intended to maintain the mainspring in place when the same is unmoved. The inner end of the mainspring 1857. Serial No. 228,021. (No model.)

G is affixed to a sleeve, e, which is of one piece with the ratchet-wheel E, Fig. 2. A clickspring, g, affixed to plate B, prevents the turning back of the ratchet-wheel E, and a lever, F, which is provided with a click, f, which moves upon the pivot C, causes the ratchet E to turn and to wind up the mainspring when it is moved back and forth. This motion is produced by'means ofthe stem J. The pendant K is affixed to the ring-L, Fig. 7, which slides on the periphery of the watch-case M, between the iillet m and glass-bezel N.

The case M is provided with a slit, n, in which the stem J slides. The crown K is connected with the stem and pinion Z, which pinion is upon the stern and acts upon the usual hand-setting gear-wheels through the medium of a pinion, r, and a sliding crownA pinion, c', when the pushpiece I and lever are acted upon and the crown turned.

The setting of the hands canonly take place when the pinions Z and r are in gear. This is the case when the pendant is placed bey ond twelve o clock. The barrel-wheel D gears into a double pinion, O, placed on the border of the plate, and which transmits the motion of barrel-wheel D tothe pinion of the center wheel, P, by means of an intermediate wheel, 0. Wheel P acts upon the pinion of a second wheel, Q, which engages with the pinion of a third wheel, R. The latter drives the pinion and escapement-wheel S, which, as well as the balance-wheel T, is the plate A.

The arbor of the escapementwheel S and balance-wheel T are supported at one end by the plate B andat the other end by the bridges U and V. (See Fig. 5.)

The large dimensions of the parts render the manufacturing of this watch so easy that no special workmen are required.

The winding up of the mainspring--that is to say, the to-and-fro motion of the lever F and of its click f-m21y also be produced by turning to and fro the metal case M of the watch`case constructed as shown in Fig. 10.

The mechanism of the watch is affixed by means of screws n to a ring, L, which carries two guide-blocks, m', in which slide the in-` wardly-turned edge u of the metal case M.

placed in an opening inv ICO The latter is provided with a pin, m, (see Fig. 9,) which engages with thelever Fin any desired manner, so as te transmit to the latter its own to-and-fro motion to Wind up the malnspring.

'Ihe pendant II is afixed through the ring L to the ring Lby means of ascrew, k, which secures at the same time the rings L and L together. The spring g, which prevents a back motion of the ratchetwheel E, is affixed to ring L or to the plate ofthe Worlz.

I claim as my invention- 1. In Watches, the combination of the pillar C, placed in the center of the Watch, With a barrel-Wheel, D, having five or more pins, d, a strong mainspring, G, a ratchetwheel, E, the click-spring g, and the ratchet-lever F, having a elickspring,f, substantially as shown and described, and for the purposes set forth.

2. The combination, with the case M, having a slit, a, the ring L, pendants K,and crown K, of a stem, J, ratchetlever F, and ratchetwheel E, for winding up the mainspring, the pinions Z and 1', push-piece I and its lever, and the crown-pinion z, for setting the hands upon the shifting of the lever F, substantially as and for the purposes specified.

3. The combination of a case, M, having a slit, n, a ring, L, bearing the pendant K, provided With a Crown, K, a stem, J, and pinion I, and pinion r, and the bezel N,substantially as shown and described, and for the purposes specified.

4. The combination, with the case, ring L, having the work-guides m m', which. slide, the edge a of the metal case M', and pin m, the Winding-up lever F, and mechanism connected therewith and to the mainspring, as shown and described, and for the purposes set forth.
