WALTER H. FITZ GERALD, OF BROOKLYN, NEWV YORK, AND EDXVARD A. MARSH, OF \VEST NEVTON, MASSACHUSETTS.

STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 338,946, dated March 30, 1886.

Application filed October 3, 1885.

To all whom it may concern:

Be it known that we, WALTER H. FITZ GERALD, of Brooklyn, in the county of Kings, State of New York, and EDWARD A. lVIARSH, of \Vest Newton, in the county of Middlesex, and in the State of Massachusetts, have invented certain new and useful Improvements in Stem\Vinding and Setting-\Vatches; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of the operative parts of our mechanism separated from each other and from the case. Fig. 2 is a like view of the same when combined for use. Figs. 3 and 4 are plan views of a watch-movement inclosed in a case-center, and show, respectively, the stem-driven train in engagement with the n'iainspring-wheel and the dialwheels. Fig. 5 is a perspective view of our intermediate device as arranged for attachment to a hunting-case, and Fig. 6 is a like view of the same in position within such case center.

Letters of like name and kind refer to like parts in each of the figures.

Our invention is an improvement in stem winding and setting watches in which the winding and setting train is placed in engagement with the winding wheel or the dialwheels by the longitudinal movement of a rotatable stem arbor; and it consists, principally, as an improvement in stem winding and setting watches, in the combination of a rotatable longitudinally movable stem arbor which has no positive connection with the watch-movement, a device which is pivoted within the case-center and adapted to communicate the longitudinal movements of said stem-arbor to the winding and setting train, and a stationary stop that is engaged by said pivoted device and operates to hold the latter at the limit of its motion in either direction, substantiallyas and for the purpose hereinafter specified.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a longitudinally-movable stem-ar-- bor which has no positive connection with the watch movement, a device that is pivoted Serial No. 178,936. (No model.)

within the case-center and by a movement upon its axis is adapted to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, means, substantially as described, whereby the longitudinal movements of said stem-arbor are communicated to and cause said pivoted device to turn upon its axis, and a stationary stop which is engaged by said pivot-ed device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose hereinafter shown.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a longitudinal]y-movable stem-arbor which has no positive connection with the watch movement, a device that is pivoted within the case-center, and by a movement upon its axis is adapted to permit the winding and setting train to be changed from engagement with the dial-wheels to the windingwheel, means substantially as described,'whereby the longitudinal movements of said stemarbor are communicated to and cause said pivoted device to turn upon its axis, and a stationary stop which is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as andfor the purpose hereinafter set forth.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a winding and setting train which is normally in engagement with the windingwheel, a device that is pivoted within the case-center, and, by a movement upon its axis,

is adapted to change the engagement of the winding and setting train from the windingwheel to the dial-wheels, a rotatable longitudinally-movable stem-arbor which has no positive connection with the watcl1-1nove1nent, and by its longitudinal movements is adapted to turn said pivoted device upon its axis, and a stationarystop that is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose hereinafter shown and described.

It consists, further, as an improvement in stem winding and setting watches, in the combination of a winding and setting train which is normally in engagement with the windingwheel, a device that is pivoted within the case-center, and, by a movement upon its axis, is adapted to permit the winding and setting train to be changed from engagement with the dial-wheels to the winding-wheel, a rotatable longitudinally-movable stem-arbor,wl1ich has no positive connection with the watch-movement and by its longitudinal movements is adapted to turn said pivoted device upon its axis, and a stationary stop that is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose hereinafter specified.

It consists, finally, as an improvement in stem winding and setting watches, in a watchcase provided within its pendant with a rotatable longitudinally -movable stem -arbor, which is adapted to engage with a suitablyconstructed watch-movement, without having a positive connection therewith, a lever that is pivoted within the inner face of the case-center and is adapted to communicate the longitudinal movements of said stem-arbor to the winding and setting train, and a stationary stop, which is secured within said casecenter in position to be engaged by the outer spring end of said lever and operates to hold the same at the limit of its motion in either direction, substantially as and for the purpose hereinafter shown.

In the carrying of our invention into practice, we employ an ordinary case-center, A, provided with a stem, B, and stem-arbor O. Pivoted near one end within the inner face of said center A, at one side of the axial opening 2; of the stem B, is a lever, D, which has its said end 01 adapted to engage with a circumferential groove or rib, c, that is formed within or upon the periphery at or near the inner end of said stem-arbor G, the arrangement being such that a longitudinal movement of the latter will cause the outer end, d, of said lever to be moved in a relatively opposite direction. The outer end, d, of the lever D engages with the rounded or pointed end, 0, of a pin or screw, E,which is inserted within the case-center A and projects downward into the path of said lever, where its said end 6 occupies a position midway between the limits of the motion of said lever end d. The screw E operates as a stop for and holds the lever D at the limits of its motion in either direction, and, in order to enable the latter'to be moved upon its axis, its central portion is made thin enough to enable its outer end to be easily sprung downward over said stop whenever the stem-arbor O is moved longitudinally, the strength of such spring being governed by the amount of resistance which it is desired that there shall be to the longitudinalmovements of said stem-arbor.

The case thus provided is intended for the reception of an ordinary watch-movement, F, in which the winding-wheel G and dial-wheels H are, when desired, connected with the stemyoke N may be respectively brought into engagement with the winding-wheel G or the dial-wheels H. A spring,0, operates to hold said yoke with a yielding pressure in position to cause said pinion L to engage with said winding-wheel, so that the winding and setting train is normally in position for winding the mainspring.

The movements of the lever D are utilized for changing the engagement of the winding and setting train from the winding-wheel to the dial-wheels by providing upon the end of the yoke N, adjacent to the pinion M, an arm, n, which extends outward to position for engagement by the outer end of said lever, the arrangement being such that an inward movement of said lever will turn said yoke to the position shown in Fig. 4, while, when said lever is moved outward, said yoke will be turned to the position seen in Fig. 3 by the operation of the spring 0.

The construction described is-adapted for cases for open-faced watches.

For hunting-cases, where the interior of the case-center A is provided with an annular recess, a, the lever D is pivoted upon a block, P, as shown in Fig. 5, which block is fitted to said recess a, andis preferably secured therein by means of screws, as seen in Fig. 6.

This improvement adapts the watch-case to receive any movement which 'is designed for it, and renders the insertion therein or removal therefrom of a movement as easy as would be the same operation in case of keywinding watches.

Having thus described our invention, what we claim is- 1. As an improvement in stem winding and setting watches, the combination of a rotatable longitudinally-movable stem-arbor which has no positive connection with the watch-movement, a device which is pivoted within the case-center and adapted to communicate the longitudinal movements of said stem-arbor to the winding and setting train, and a stationary stop that is engaged by said pivoted device and operates to hold the latter at the limit of its motion in either direction, substantially as and for the purpose specified.

2. As an improvement in stemwinding and setting watches, the combination of a longitudinally-movable stem-arbor which has no positive connection with the watch-movement, adevice that is pivoted within the case-center and by a movement upon its axis is adapted to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, means, substantially as described, whereby the longitudinal movements of said stem-arbor are communicated to and cause said pivoted device to turn upon its axis, and a stationary stop which is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose shown.

3. As an improvement in stem winding and setting watches, the combination of a longitudinally-movable stem-arbor which has no positive connection with the watch-movement, a device that is pivoted within the case-ecu ter and bya movement upon its axis is adapted to permit the winding and setting train to be changed from engagement with the dial-wheels to the winding-wheel, means, substantially as described, whereby the longitudinal movements of said stem-arbor are communicated to and cause said pivoted device to turn upon its axis, and a stationary stop which is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose set forth.

4. As an improvement in stem winding and setting watches, the combination of a winding and setting train which is normally in engagement with the winding-wheel, a device that is pivoted within the case-center and by a move-- ment upon its axis is adapted to change the engagement of the winding and setting train from the winding-wheel to the dial-wheels, a rotatable longitudinally-movable stem-arbor which has no positive connection with the watch-movement and by its longitudinal movements is adapted to turn said pivoted device upon its axis, and a stationary stop that is engaged by said pivoted device and operates to lock the same at the limit of its motion in either direction, substantially as and for the purpose shown and described.
