IMPROVEMENT IN STEM-WINDING AND SETTING-ATTACHMBNT TO WATCHES.

The Schedule referred to in these Letter! Patent and making part 'of the sama.

To all whom it may concern;-

Be it known that I, VITALrs HIMMER, of Brooklyn, in the county of Kings, and State of New York, have invented a new and improved W'indingand Set ting-Attachment to IVatches; and I vdo hereby declare that the following is a full, clear,l and exact description thereoi`,iwhich will enable others skilled in the art to .make and use the same, reference being had to the accompanying drawings, forming p'art 0f this specification, in which- Figure l represents an enlarged face .view of a watch provided with my improvements.

' Figure 2 is a central section of the same, taken on the plane of the line x x, tig. 1.

Figure 3 is a detail transverse section of the same, taken on the plane of the line y y, fig. 1;

Similar letters of reference indicate cones'pondin parts.

This invention is based upon the improvements in stem-windingwatches for which Letters Patent No. 86,751 were granted to me, on the 9th day of February, 1869, and has for its object to simplify the winding-attachment'therein described,.to make both the setting and wi:Kling-attachments controllable .by the stem of the watch, and to prevent the closing of the ease in hunting-case watches, as long as the setting-attachment is in gear.

The invent-ion consists, first, in the use of a jointed plate, iu place of' the spring-plate acted upon by the pin on the drum. Thereby less friction and consequent easier action are obtained.

The invention also `consist-sin av novel manner of hinging, or rather fastening the' aforesaid jointed plate.

A, in the drawing, represents the case of the watch.

B is the upper plate, under the dial.

C-is the stein, and

a, the crown-wheel turned by the same.

The stem is so arranged, that it .will slide in the case, and is polygonal where it fits loosely through the crown-wheel. 1t will, therefore, not affect the p0- sition of the same, when moved longitudinally, while, when turned, whether drawnrout or pushed in, it will always turn the crown-wheel.

. The stem is cylindrical outside of the crown-wheel, as shownin iig. 2, and has-a groove, b, cut around it, into which a pin, o, projecting ii'om a plate, D, is fitted.

The plate D is, by a pin, (l, pivoted to the plate B, and is, when the stem is drawn out, swung out against the riln ofthe case.

A pin, e, fitted loosely through the rim oi' the case, is connected with the plate D, and is pushed out when the stern is drawn. The outward motion ofthe stem is arrested by the plate D, when the same strikes against-the rim of the case.

The crown-wheel'a meshes into the teeth of a'wheel, f, which turns on the plate B, and which transmits motion to oneof two pinions, g and h.

The pinion g is hung on an elbowplate, IJ, which is pivoted at i to the plate B, and which, by a pin, j,.is connected with the plate D. 4When the stern is drawn ont, the plate E is so 'swung by D that its pinion g is thrown into gear with the'pinion k, on the minutel f pushed out of the oase, and prevents the locking of the case. The setting-apparatus can, therefore, not be aecidentally retained in gear after the hands are set, as the case cannot be closed. For hunting-case watchesv this device is of great value. For open-cased onesit is, of course, to be dispensed with.

The drum H' of the watch carries the fingered wheel x substantiallyas described in my aforesaid Letters Patent, and acts on the pin m to elevate the same,

when the spring is Wound up, as fully described'there- The pin lm, when piished up, acts on a plate, I, that is, by a pin, n, pivoted to the plate G. 'lhe plate G is fitted upon a pin, 0,' that is the centre oi' the wheel f. The pin o locks to theplate B a small plate, p, which fits into a slot of the plate G, and over a crossba'r, o', formed on the same, as indicated in fig. 2', and by dotted lines in i'g. 1. lhe plate G can thus swing on the pin o with the plate p, and can also swing rertieally on the cross-bar r.

The pinm, when pushed up, mises the plate I, which Aforms part of G, and'thereby causes .the latter to swing up on r. When the plate I is lthus raised, its end slides, on the vbevelled end of a pin, u, and it is thereby pushed in toward the stem:` But as adirect motion cannot thus he produced, the plate I will turn on its pivot n, to make a knee, and the plate G. will also turn in a similar manner on the pin o, and will thereby throw the wheel h-out of gear with the wheel s, that is mounted on the spindle of the mainspring.

lhe winding-attachment is, therefore, disengaged as soon as the main-spring is entirely wound up. -It is also disengaged when the stem is drawn out, as then the plate D will act on the plate p, to swing G, whereby the wheel h is carried away from S.

A spring, t, has the tendency to hold the plate G in such position that the winding-attachment is in gear.

The pin u is connected with a. strong spring, V, to be yielding to a certain degree.

The wheel g rests on an inclined snrfaceras in g. 2, to be in gear with the wheels f and le, which are in different planes, as shown.

lhe stem-head wis for hunting-ease watches, movable on the body ofthe stem, to operate independently of the mechanism for opening the case;

Instead of the jointed plate G I, a spring plate may be used, substantially as in my formen patent.

Having thns described my invention,

I claim as new, and desire to secure by Letters Patent- 1. The jointed plate G I, acted upon by the pin m of t-h'e main-spring drum, for throwing the windingattaehment out of gear, substantially as herein shown and described.

2. The plate G, when slotted and fitted around the swivellcd plate p, which rests on a cross-bar r of the plate G, so that the letter can be turned horizontally and vertically, substantially as herein shown and described.

VITALIS HIMMER.
