PHILLIP H. WHEELER, OF SPRINGFIELD, ILLINOIS.

STEM-WINDING WATCH.

SPECIFICATION forming part of Letters Patent No. 238,464, dated March 1, 1881.

Application filed December 11, 1880.

To all whom "it may concern Be it known that I, PHILLIP H. WHEELER, of Springfield, in the county oi Sangamon and State of Illinois, have invented a new and valuable Improvement in Stem-Winding Watches; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference beinghad tothe annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

The figure of the drawing is a plan view of the mechanism.

This invention relates to the setting devices for stem-winding watches.

The invention consists in the construction hereinafter described, and particularly pointed out in the claim.

Inthe drawing hereto annexed, A is the pillar'plate.

B is the yoke, pivoted at a, and carrying the bevel -wheel 0. Through this the pendant winds and sets the watch.

Upon end D of yoke B is journaled the bevel-wheel D, through which wheel 0 winds the watch. The other end, E, ofsaid yoke carries another bevel-wheel, E, journaled at c to mesh with wheel 0. This end extends beyond said wheel E into a recess, f, of the pillarplate A. This extension is beveled off at e, and has the corner cut off at g.

G is a pawl pivoted near the bevel e, and when loose its end h is forced by a spring, H, against such bevel.

I is a finger-bar pivoted at it, and when shoved inward, having its end 70 hearing against the end E of the yoke and a thumbpiece, I, projecting through opening a in the (Model.)

watch. \Vhen this finger-bar is shoved in it presses pawl G from off end E, releasing the yoke B, and permitting spring N to hold the wheel. D into engagement with awheel within for winding the watch. When finger-bar I is withdrawn spring H throws pawl G around, and its point h, riding up bevel c. forces the end E of the yoke B in, releases wheel I) from engagement, and rests upon the cut-off corner g. This action throws bevel-wheel E into engagement with the minute-wheel, when, by operating the pendant, the hands can be turned in either direction and the watch set.

It will be noticed that when the finger-bar I is shoved in and pushes the pawl Gr away said pawl bears, by its end,p, against the fin- &

ger-bar, and by its friction prevents the accidental displacement of the same.

A swing-yoke in a stem-winding and handsetting watch has heretofore been held and released by a pivoted lever, and I claim protection only for the peculiar construction herein shown, described, and specifically claimed.

What I claim is- In a stem-winding watch, the combination, with the yoke B, having one extension carrying a wheel, D, and an opposite extension beveled at its end at c, and cut away at g. carrying a bevel-wheel, E, of the springs H and N, pivoted pawl G, and pivoted fingerpiece I, substantially as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

PHILLIP H. WHEELER.
