IMPROVEMENT IN -SIEM-WINDING WATCHES.

TO ALL WHOM IT MAY CGNCERN:

Be it known that I, ARTHUR Wanswoaru, of Newark, in the county of Essex, and State of New Jersey, have invented a new auduseful Improvement in Watches and I do. hereby declare that the following is s full, clear, and exact description thereof, which will enable those skilled the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification.

The present invention relates to that class of watches for the winding and setting of which no key is required, and in which both operations are performed by simply turning the pendant to the watch-case; and this invention consists, rst, in an improvement upon the manner of hanging the adjustable gears interposed between the pendant and the main-spring axis and-the handairbor, respectively, whereby their arrangement is much simplified and rendered more convenient in use; secoild, in combination with a pendant arranged to turn, a pusher so connected as to turn in conjunction therewith, and thus through it turn the main-spring axis or the hand-arbor, accordingl to which is in connection with such pendant, while at the same time the pusher is free to play in and out for opening the watch-case, as in watches opening through a p'usher; third, in applying a packing-ring about the pusher and between it and the pendant, to prevent dirt and dust from passing through the same to the watch movement. In the accompanying plate of drawings, my improvements in watches" are illustlated- Figure I' being an inside view of the watch with the dial-face or plat-e removed, showing the arrangement and connection of parts between pendant and main-spring axis and hand-arbor for winding and setting.

Figure 2 is a section taken in the plane of the line :v z, iig. I, which is across the watch-case, and in aline at right angles to the length and direction of the pendant-pusher.

Figure 3, a plan or top view of the pusher, the pendaut-ring, and the portion of pendant inwhich the pusher is arranged to move.

Figure 4, a section through pendant, taken in the plane of the line y y, iig. I; and

Figure 5, a view of one face of the wheel with which the pendant is connected, and through which the main-spring axis and hand-arbor are operated by the intermediate gears between them and the said wheel, engaged with the pendant.

Similar letters of reference indicate corresponding parts.

A, in the drawings, represents the rim or body to a watch-case, B the pendant, and C the pendant-ring; D, a plate secured in watch-case rim A, on which plate the parts for winding and setting are arranged, as will be now explained. E, the main-spriug axis, carrying gear-wheel F of suitable size; G, the hand-arbor, also carrying gear-wheel H; I and I2, two gear-wheels of similar size. These gears I and I2 are hung to a common bar, J, placed across the plate D at right angles to the length and direction of the pendant, and with its two ends projecting through ways a, cut in the flange b to the watch-case rim A. This bar J is secured to the plate D by a set-screw, c, that passes through a longitudinal slot, d, in the bar, bywhich screw and slot it is guided in its movement across the plate. The bar J is also so located as to have its gear I in connection with the gear or main-spring axis with the other gear I2, through its concentric pinion d, secured to its under side, out of connection with the gearf andpinion g, interposedibetween it and the gear to the hand-arbor; K, a bent spring, secured at one-end to the inside of the watch rim A, with its other end engaged with the cross-bar J, hereinbeL fore referred to. This spring, while acting to hold the gear Iz of the bar J disengaged from the train of gears between it and the hand-arbor, yet allows the said bar vto be moved suiciently to bring the said gear I, by its pinion, into connection with the hand-arbor, and a gear-wheel, L, arranged to turn upon an axis of the watchplate D, at the same time disconnecting the gear I from the gear-wheel L, just above referred to. With the gear-wheel L, by crown-teeth upon its under side or face, as shown in iig. 5, a pinion, M, engages, which is secured to the lower end of a stem, N. This stem is secured in the pusher O to the pendant in a similar manner to that described in the Letters Patent hereinbefore referred to as granted to me, so that while the pusher can have a. lateral play upon such stem, if theV pusher is turned such stem will be turned with it, and thus through its pinion turning the gear with which it is connected, as has been explained. The pusher 0 extends through the pendant, projecting at its outer end therefrom suiiiciently for its inward movement to operate the catch= spring to the watch-caso ss in ordinary hunters watchesr Z,` a rib along one side of pusher-0, by which rib vthe pusher is engaged with a corresponding shaped groove, m, in the portion P of the pendant, as shown in iig.

3 more particularly. This part P of the pendant is hung on the other part O, fixed to the watch-body A so that it can be turned around thereon,and thus, through it, the pusherl O, because of its connection by a. spline- `ioint therewith, and through such pusher the pinion and other parts which may be in connection therewith. S, a. packing-ring of rubber or other suitable material around pushei` O, and between it and the pendant, to prevent dirt or dust from passing through the pendant to the watch-movement. By the arrangement of' the bar J carrying the gears I and I2, the main-spring can be wound at any time, Whether the watch-case is opened or Y closed, by simply turning the pendant in the proper direction therefor, it being impossible to wind it in the Wrong direction, even if the pendant is so turned, as the power exertednpon the wheel L and the connectinggear Ispends itself upon the spring R, that is connected with the bar T, causing the said gear I to turn upon the wheelF to the main-spring axis without moving such Wheel. To set the hands the bar .I at its end T is first pressed inward suicient to establish the necessary connection of parts lbetween them and the pendant, at the same time breaking the connection between the pendant and the main-spring axis, and then the pendant turned to the right or left, as maybe necessary.

I claim' as new, and desire to secure by Letters Patent-- 1. The bar J, carrying Wheels and I2, interposed between the pendant and the :nain-spring axis, and handarbor, respectively, of a watch-movement, substantially as and for the purpose described.

' 2. The combination of a turning-pendant and pusher, when connected together in n. watch, substantially as described for the purpose specified.

3. The packing-ring s, or its equivalent, between'the pendant and pusher of a Watch-case, substantially as and for the purpose described. l

The above specification of my invention signed by me this 16th day of May, 1867.
