STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 451,600, dated May 5, 1891.

Application filed May 26, 1890. Serial No. 353,223. (No model.)

To ctZZ whom it may concern:

Be it known that I, ROSWELL E. MORELAND, a citizen of the United States, residing at Trenton, in the county of Mercer, in the State of New Jersey, have invented certain new and useful Improvements in Stem Winding and Setting \Vatches, of which the following is a specification.

My invention relates to an improvement in stem winding and setting Watches, containing an interchangeable stem-wind and means for adapting a movement containing a stem winding and setting mechanism to open face or hunting-case at pleasure; and the object of my invention is to provide and connect certain operative parts of the winding and setting mechanism which will assemble and work interchangeably in both hunting-case and open-face watches without requiring the addition or subtraction of any part in either situation, as set forth substantially in this specification and the accompanying drawings, in which- Figure l is a plan view of my improved setting and winding mechanism in its normal or winding position in an open-face watch. Fig. 2 is a plan view of mysaid improved mechanism in setting position in an open-face Watch. Fi 3 is a similar view of said mechanism in winding position in a hunting-case watch. Fig. 4 is a similar view of said mechanism in setting position in a hunting-case watch, and Fi 5 is a vertical plan view of a movement containing my improvement and showing the two positions of the windingbridge.

In the drawings like letters indicate like parts.

A is the plate; B, the yoke; a, the hourwheel; I), the cannon-pinion; c, the minute- Wheel; cl, the ratchet-wheel; e, the windingpinion; e, the slot for winding-pinion in hunting-cased movement; 0 the slot for wind ing-pinion in open-faced movement; f, the ting-lever; g, the click; 72, the click-spring; the stein-arbor; j, the crown; 7c, the first intermediate wheel; Z, the stud for intermediate setting-wheel, and m the stud for the minutewheel in an open-faced movement; a, the stud for the minute-wheel, and 0 the yoke-screw hole in plate in a hunting casecl movement; 19, the yoke-screw hole in plate in an openfaced movement; q, the yoke-screw; r, the intermediate setting-wheel; s, the second intermediate wheel; '6, the yoke-spring; it, the slot for the yoke-spring in a hunting-cased movement; n, the slot for the yoke-spring in an open-faced movement; 10, the slot for the lever in a hunting-cased movement; on, the slot for the lever in an open-faced movement; y, the lever-screw hole in a hunting-cased movement; 11 the lever-screw hole in an open-faced movement; .z',the winding-bridge in an openfaced movement; 5, the winding-bridge in a hunting-cased movement, and I, II, and III are studs in the yoke.

I11 Figs. 1, 2, 3, and 4 the yoke B is simply outlined, and the wheels covered by it are shown in their different positions. In Fig. 1 the stem-wind train is shown in winding position in an open-face watch, the second intermediate wheel 8 being meshed with the ratchet d and out of gear with the intermediate setting-wheel 4". By pulling out the lever f the winding-train mounted on the yoke B is-thrown into setting position, as shown in Fig. 2, the second intermediate wheel sbeing thrown out of gear with the ratchet-wheel d and into gear with the intermediate settingwheel 1'. In each position of the train the yoke 13 is maintained in its place by the yokescrew q, and its points bearing against the peripheral wall of the plate A regulate the depthings in the winding and setting positions. By removing and reassembling the parts of the winding and setting mechanism in the manner hereinafter described the openface movement may be changed to ahuntingcased movement. (Shown in Figs. 3 and 4.) In Fig. 3 the stem-winder changed to a hunting movement is shown in its normal or winding position, the second intermediate wheel 5 being shown meshed with the ratchet-wheel (Z on the side thereof opposite to the position indicated in Fig. 1. The minnte-wl1eel c having been removed from its position in Fig. 1 and mounted on the studn, (shown in Fig. 1,) by pulling out the lever f, the winding-train is thrown out of gear and the intermediate setting-wheel ais meshed with the minutewheel, as shown in Fig. 4. To make these changes possible a peculiar construction of parts of the plate A and the winding and setting mechanism is essential. There are two slots in the plate A for the winding-pinion c, the slots used in the hunting movement being indicated by c in Figs. 1 and 2, and that used in open-face being shown at e in Figs. 3 and 4. There are also two holes to receive the yoke-screw q, that used in the hunting movement being shown at 0 in Figs. 1 and 2, and that used in open-face is shown at p in Figs. 3 and 4:. There are two holes to receive the lever screw, one for the hunting case, (shown at y in Figs. 1 and 2,) and the other for open face,(shown at y in Figs. Sand 41.) There are, as well, two studs for the minute-wheel c on the plate A, that used in the hunting move ment being shown at n in Figs. 1 and 2, and that used in open face being shown at m in Figs. 3 and at. The plateA also bears a stud, on which the intermediate setting-wheel r is mounted in the open-face movement. (Shown by Zin Figs. 3 and at.) The peripheral wall of the plate A is provided with duplicate slots in the proper positions for open-face and hunting movements for the lever f, the click g, the click-spring h, and the voke-spring t, as 2 5 shown in the drawings. The yoke B contains three threaded holes, marked, respectively, I II III, into which are screwed the studs on which are mounted the intermediate wheels. There are but two of these yoke- 0 studs necessary. That marked I is permanently seated in the yoke, and against which the spring 15 bears in the open-faced movement, but carrying the wheel .9 in the hunting-case movement, while the other yoke-stud 3 5 is attached at II in the open-face movement to carry the wheel 9' in its different positions, and at III in the hunting movement. The wheels 0' and s are preferably of the same size, so as to be readilyinterchangeable. On the under side of the plate A are two sets of screw-holes for attaching the winding-bridge in its two positions, (shown by and .2" in Fig. 5.)

Having thus referred to and described the parts of my interchangeable stem winding and setting mechanism, I shall now describe the manner of changing the winding and a setting mechanism in an open-face movement to a hunting movement and from a hunting 5o movement to an open-face movement.

To change to the hunting movement from the open-face movement, (indicated in the drawings in Figs. 1 and 2,) first remove the barrel-bridge. (If in a full-plate movement,

5 remove the top plate.) Then change the winding-pinion e to the slot 6, (indicated in Fig. 1,) as shown in Fig. 3, the winding-bridge being thus shifted from .2 to .2" in Fig. 5. Then change the lever f and attach the same at le ver screw-hole 3 (indicated in Fig. 1,) as shown in Fig. 3. Next remove the yoke and change stud II to the hole in the yoke designated by III, and place the intermediate setting-wheel r, Fig. 1, and the second intermediate wheel 3, Fig.1, on the studs I and III i11- differently, if the wheels are alike. Then place first intermediate wheel 7c in position over yoke screw-hole 0, (designated in Fig. 1,) as shown in Fig. Next place the yoke in position, pass the yoke-screw (1 through the yoke and intermediate wheel 7t, as shown in Figs. 3 and 4c, and screw fast. Then remove yoke-spring if from its position in Fig. 1 and insert itin the slot u (indicated in Fig. 1) and adjust the same, as shown in Fig. 3. Finally, shift the minute-wheel c from its position (indicated in Fig. 1) to the stud n, (indicated in Fig. 1,) as shown in Fig. 3. This completes the change from open-face to hunting move ment.

To change the stem-wind from hunting to open-face movement, first remove the barrelbridge (or top plate) of movement, as above described,and change thewindii'ig-pinion from the slot 6 to the slot 0 (designated in Fig. 3,) as shown in Fig. l, the winding-bridge being thus changed from .2" to (Shown in Fig. 5.) Next change the lever f to the lever screwhole t (indicated in Fig. 3,) as shown in Fig. 1. Then remove the yoke and change stud III to stud-hole II in yoke and place the first intermediate wheel 713, Fig. 3, over yoke screwhole 19, (indicated in Fig. 3,) as shown in Fig. 1. Then place the other stein-wind wheels in position, as shown in Fig. l, and screw on the yoke. Then change the yoke-spring t to the slot Q) (indicated in Fig. 3) and adjust the same to the yoke, as shown in Fig. 1. Finally, change the minute-wheel c, Fig. 3, to stud 'm, (indicated in .Fig. 3,) as shown in Fig. 1, and the change is complete.

I consider it preferable that the wheels 7;,

r, and s be made of one size; but this is not essential, as by slightly changing the position of the studs the wheels may be made of different sizes. I have also shown the winding-pinion e and the first intermediate wheel 7o with straight teeth; but it is obvious that they may be made with beveled teeth.

It is obvious that the mechanism shown and described by me may be varied in its details to a greater or less degree without departing from the spirit of my invention, and I do not desire to be confined to the use of all the de tails herein shown, nor. to the exact forms thereof; and

that I claim as new, and desire to secure by Letters Patent, is

1. In a watch-movement comprising stem winding and setting trains, the combination, with a plate forming a permanent part of the framework and having duplicate bearings for the shiftable parts of the movement, of a shiftable winding and setting stem and a yoke having bearings for wheels comprised in the winding and setting trains, said yoke adapted to be shifted from one bearing to another on the plate and the wheels on the yoke adapted to be arranged in the bearings, so as to mesh with the winding and setting trains in either position of the yoke, substantially as described.

2. In a watch-movement comprising stem winding and setting trains, the combination,

with a plate forming a permanent part of the frame-work and having bearings for part of the wheels of the windin g and setting trains, of a yoke also mounted in bearings on said plate and carrying bearings for other wheels of the winding and setting trains, the bearings on the plate forthe yokebeing duplicated, so that it maybe shifted from one position to another, and the bearings on the plate for the shiftable wheels of the setting-train being also duplicated, so as to permit the rearrangement of the winding and setting trains to correspond with the altered position of the yoke, substantially as described.

3. In a stem winding and setting watch, the combinatiomwith a supporting-plate forming a part of its permanent frame-work, of winding and setting trains comprising a mainspring-drum and hour-wheel mounted in permanent bearings upon said plate, a minutewheel shiftable upon said plate, and a yoke bearing wheels comprised in said trains and intermediate between the winding-stem and mainspringdrum and minute-wheel, said yoke being shiftable upon the Permanent plate, the permanent plate being provided with bearings for interchangeably assembling the winding and setting trains either for an open-face Watch or for a hunting-case watch, substantially as described.

4. In a stem winding an d setting watch, the combination,withaplateforminga permanent part of the frame-work and having bearings adapted to receive the changeable parts of the movement in different positions, of a fixed mainspring-d rum, a shiftable yoke, and wheels comprised in the winding and setting trains carried by the yoke for winding the spring and setting the hands in either position of the yoke, substantially as described.

5. In a stem winding and setting Watch, the combination, with a plateformin g apermanent part of the frame-work and having slots and bearings for the changeable parts of the movement, of a fixed mainspring-drum, a changeable yoke carrying wheels comprised in the winding and setting trains, and a changeable minute-wheel, substantially as described.

6. In a stern winding and setting watch, the combination, with a plate forming a part of the permanent frame-work and adapted to receive changeable parts of a movement in their different positions, and a fixed mainspringdrum, of a shiftable yoke carrying wheels comprised in the winding and setting trains, said yoke being pivoted eccentrically to the mainspring and adapted to vibrate during the back action in winding the watch, substantially as described.

- 7. In a stem Winding and setting watch, the combination, with a supporting-plate forming a permanent part of its frame-work, of stem winding and setting trains having interchangeable wheels, a yoke mounted in bearings on said plate and adapted to be shifted to the required position for either an open-face or a hunting-case movement, part of the wheels of the winding and setting trains being carried by the yoke and part mounted in bearings on the plate, the bearings for the yoke and the wheels being duplicated, so that the wheels of the winding and setting trains may be shifted and interchanged to correspond with the altered position of the yoke, substantially as described.
