STEM \NiNDlNG AND SETTING WATCH.

SPECIFICATION forming part of Letters Patent No. 408,274, dated August 6, 1889.

Application filed March 30, 1889. Serial No. 305,435. (No model.)

To aZZ whom it may concern:

:le it known that I, ALBERT TROLLER, residing at Rockford, in the county of VVinnebago and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Stem \Vindin-g and Setting \Vatches, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is a plan showing the inside of the top plate and thebarrel-bridgeinacase. Fig.

2 is a plan showing theinside of the top plate.

Fig. 3 is aplan showing the outside of the top plate and the winding and setting mechanism in view. Fig. at is an under side view of the barrel-bridge. Fig. 5 is a perspective of the barrel-bridge and some other parts. Fig.

0 is a sectional view at line 6 of Fig. 1. Fig.

7 is a section at line 7 of Fig. Fig. Sis the same as Fig. '7, showing some of the parts in a diiferent position. Fig. 9 is a detail, being a section of the parts shown, taken at line 9 of Fig. Fig. 10 is the same as Fig. 9, the

parts being in a different position. Fig. 11 is a detail, being an elevation of the shiftinglever a and its spring. Fig. 12 is asection at line 12 of Fig. 11. Figs. 13 and 14 are details, being views of the switch-arbor. Figs.

1 to 7, inclusive, are somewhat enlarged.

Figs. 8 to 14, inclusi e, are about three times full size.

lVinding and setting devices which can be brought into position and operated by a longitudinally-inovable stem-arbor or stem-key are common, and cases for movements eontaining such devices are called pendantset cases. A stem-key which is not longitudinally movable is frequently used for winding and setting, the setting devices being brought into position by a lever operated by hand, and cases for movements containing such devices are known as lever-set cases.

The leading objects of my invention are to provide improved devices by means of which a stem-driven train in a pendant-set case can be brought into engagement either with a dial-wheel or the winding-wheel at pleasure,

and to provide awatch-movement containing the said improved devices, with devices which adapt it to be used in an eXclusivelylever-set case as well as in a pendant-set case, which I accomplish, as illustrated in the drawings and hereinafter described.

That which I claim as new will be pointed outin the claims.

In the drawings, A represents a portion of the center band of awatch-case provided with a pendant and a longitudinally-movable stemarbor, which may be con stru cted in any known suitable manner, and therefore I have not shown or described them in detail.

B is the top plate.

O is the barrel-bridge. The upper plate is not shown; but it and the barrel-bridge are both supported by the plate B. The two plates are recessed on theirinsides to receive the train. This construction, however, is made the subject of another application, and therefore these parts will not be here more fully described.

E is the stem-arbor or stem-key.

F is a yoke pivoted upon a hub and held by a cap and screw, as usual. At one end of this yoke there is a wheel G to engage with a Wheel attached to the mainspring-arbon At the other end of the yoke is pivoted another wheel H, which can be made to engage one of the dial-wheels. These two wheels G II are driven by an intermediate wheel, which is driven by the pinion I, as usual, which pinion is upon the piece which receives the inner end of the stem arbor or key, and is supported in the sleeve 'r, which is supported in a bearing formed in the barrel-bridge and plate B. 8 5

a is the lever that shifts the yoke when the movement is used in a pendant-set case. One

end of this lever is pivotally secured at 1) upon a wall formed in the barrel-bridge. The other end is free. 0

c is a spring, which, as shown, is made integral with the lever a.

(l is a recess or groove in the lever a.

e is a pin which serves the purpose of a stop. 5

f is a pin, which is secured to the yoke F and passes through a slot or hole in the plate B and projects beyond the inside of such plate. The end of this pin is beveled, and it is so arranged that the free end of the shifting-lever Ct can come in contact with and pass over such inclined end.

g is a sliding pin with which the inner end oi the stem arbor or key can come in contact to push itinward. The inner end of this pin is beveled and arranged to engage with a bevel r on the edge of; the lover a. (See Fig.

71 a switch-arbor, one end of which supported in the plate I). The other end passes through the barrel-bridge, and is provided with a notch to receive a screw-driver for the purpose of partially rotating the same.

i a pin which passes through the arbor h and projects from opposite sides thereof. One end of this pin is beveled to facilitate its passage into the groove (1 in the lever to.

J is a lever for the purpose of moving the yoke, so that the wheel II will. engage with the dial-wheel. This lever is pivoted at j, and is provided with an arm 7.:, which can be made to act upon the yoke by drawing out the arm. Z at the other end of the lever. This lever is not designed to be used when the movement is .in a so-called pendant-set case; but it is for use when the movement used in aleverset case.

In Fig. 1 are two letters P and L. \Vhen the notch in the switeluarbor his in line with the letter 1, the movement is adapted :l'or use in the pendant-set case. \Vhen such notch in. the switch-arbor is in line with the letter 11, the movement can be used in a leverset case, as will be hereinalfter more t'ully described.

s is a spring which acts on. the yoke F.

t is a spring which acts on the lever J.

The operation is as follows: Suppose the movement to be in a pendant-set case, the switch-arbor 71. being in the position shown in Figs. 1 and l and the stem-arbor pushed in as shown in Fig. 8, which will force the bew eled end of the sliding pin g over the incline r on the edge of the lever (I. Then the free end of the lever will be forced away fromthe plate B and pin and the spring 5 willbring the yoke into such. position that the wheel G will engage with the windingavheel attached to the 1nainspring-arbor, which is the normal position. of the parts, as shown in Fig. 10. It now the stem-arbor be withdrawn a littie, as shown in Fig. 7, the action. of the spring a will cause the free end of the lever (I to pass over the incline upon the end of the pin f, as shown in Fig. 9, which will force the yoke into such position that the wheel It will engage with one of the dial-wheels, ready for set-ting. By again pushing in the stemarbor the free end of: the lover a willbe again carried away from the pin 1'', and by the action of the spring .3 the wheel G will be again brought into engagement with the windingwheel. It will be observed that the shiftinglever a works at right angles to the stem-key.

If it be desired to use the movement in a lever-set ease, the lover a can permanently be brought out of action by turning the switcharbor 71. until the notch in the end l'llOl'OOii comes in line with. the letter L, which will cause the beveled end. of the pin i to enter the groove (Z in the lever (t, which will early the free end of such. lever (t away from the plate 13, bringing such lover a into an inoperative position, and then. the spring s will bring the yoke into the 'msition in which the wheel G will. be in engagement with the winding-wheel. The inclined end of the pin 1'. in the switch-arbtn: comes in. contiiwt with the switch c when the switch-arbor is in the position which it is to occupy when the move ment to be used. in a le\"e1.'setease, and the other end of such pin '1' comes in COlliflUi] with the same stop whenthe switeh-arbor is in the position which it is to occupy when the movement is to be used in a pendant-set case.

3y means of. the lever J the position of the yoke can be shifted, bringing the wheel ]I' into engagement with one of the dial-wheels, ready for setting.

\Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a stem winding and setting watch, a lever o acting at right angles to and ai'lapted to be acted on by a stenrlcey, in combinal ion with. a pinfon theyolce F, which pin passes through a slot or hole in the plate l and is arranged to be acted on by the shifting-lever, substantially as and for the purpose speci fied.

2. In a stem winding and setting watch, a stem-key having a beveled point, in combination with shitting-lever (I, with one edge of which the stein-key engages, aspring s, and a pinf, connected with the yoke F, which pin passes through the plate .13, and is arranged to be acted on by the shifting-lever (I, substantially as and for the purpose s j (.a.:ilicd.

3. In a stem winding and setting watch, the combination of a switch-arbor 71 with the shifting-lever a, for the purpose oi. holding the lever a out of action when. desired, where by the same movement is adapted to be used either in a pendant-set case or .in an exclusi velylever-setease, substantially as spcci lied.

In a stem winding and. setting watch, a switch-arbor 71, provided with a pin 1', in combination with a shitting-lever (I, provided with a groove (7, substantially as and (or the purpose specified.

5. In. a stem winding and setting watch, a shifting-leveru, in combination with a switcharbor 71, ctnistructed and arranged as do scribed, whereby such switch-arbor van be operated from the onlsideot lhe plate ll, snhstantially as speeiliml.
