STEM WINDING AND SETTING WATCH.

SPECEFICATION forming part Of Letters Patent NO. 728,090, dated May 12, 1903.

Application filed May 28, 1902. Serial No. 109,332. (No model.)

To LtZZ whom, it may concern:

Be it known that 1, WILLIAM W. DUDLEY, of Trenton, New Jersey, have invented certain Improvements in finding and Setting Mechanism for Watches, of which the following, in connection with the accompanying drawings, is aspecification, like characters on the drawings designating like parts.

This invention relates to watches, and has for its object the production of a simple, inexpensive, and efficient winding and setting mechanism for movements designed for use interchangeably in cases of different manufacture, but having pendants with reciprocating winding-stems of standard types, usually with squared ends and of a length suitable to permit readyinsertion and withdrawal of the movement, the novelty of myimprove-.

ments residing in the construction and arrangement of parts, to be illustrated and described fully in the accompanying drawings and specification and pointed out in the claims.

In the drawings, Figure 1 is a view in side elevation of one of the plates of a watch in the construction of which my improved Winding and setting mechanism has been embodied, only enough of the parts being shown to enable the invention to be understood; and Fig. 2 is a view in side elevation of the reverse of the same plate and parts.

In the embodiment of my invention selected for illustration and description as a convenient form to enable a ready understanding of my improvements the part designated by the reference-numeral l is a winding-arbor, which is seated in a groove a in the plate A of the watch-movement, in which groove it is free to reciprocate axially, its actuation being accomplished through the arm 3 of a bell-crank lever 4, which arm enters a groove 2 in the arbor, this lever being pivoted at 5 to the plate A and having a post 6, which projects through a hole ct in the plate.

The actuating means consists of a strong spring 7 upon the opposite side of the plate A from the lever 4, the free end 8 of this spring bearing against the post 6 and tending normally to throw the arbor outward toward the periphery of the plate, this movement of the arbor being controlled by the poanism.

sition of the stem, as usual in Watches of this type, but not shown in the drawings, forming no part of this invention.

It will be understood by those familiarwith the art that the stem is contained in the pendant ot the watch, having means to retain it in a pushed-in position and a pulled-out position, and that when in the pulled-out position it will permit the arbor to respond to the action of the spring 7 and take the position illustrated, while when the stem is in the pushed-in position it will hold the arbor in its innermost position against the action of the spring 7.

Upon the arbor 1s a clutch-sleeve 9 to engage the winding and setting mechanism, re spectively, and having a groove 10 to receive the free end 11 of a lever 12, which lever is extended past the post 6 and is actuated by the same when the latter is operated by the spring 7, the clutch at such time being thrown down into engagement with the setting mech- The lever 12 may have a cam-surface 13 to be acted upon by the post, or other suitable arrangement of the lever-su rface may be adopted. When the arbor is returned to its innermost position, the spring 7 is forced back positively, and thelever 12 and clutchsleeve are thrown bya spring 14 into engagement with the winding-ratchet, the spring 14: serving as a click-spring in well-known fashion. An arm 15 on the spring 7 serves to retain the setting-wheel 16 in place.

Having thus described my invention fully, what I claim, and desire to secure by Letters Patent, is

l. A winding and setting mechanism for watch-movements; comprising a grooved, reciprocating winding-arbor; a bell-crank lever one arm of which enters into said groove on said winding-arbor, the other arm having a post to pass through a plate of said movement; a movement-plate provided with a bearing for said arbor and having a hole to permit projection of said post to the other side of said plate; a grooved clutch-sleeve movable axially on said arbor into winding and setting positions; a clutch actuating lever having a cam-surface to be acted upon by said post; a spring mounted on said plate and bearing against said post, said spring tending ICO 10 tnate said lever having an arm that extends 1 over said wheel and retains the latter in place.

Signed at New York, in the county of New York and State of New York, this 20th day of May, A. D. 1902.
