SPECIFICATION forming part of Letters Patent No. 351,392, dated October 26, 1886.

Application filed January l1, 1886. Serial No. 188,160.

To all whom it may concern:

Beit known thatI, CrmnLEs F. MonniLL, a citizen of the United States, residing at Boston, in the county ofSuffolk and State of Massa` chusetts, have, invented certain new and useful Improvements in Pendant Vinding and Setting Vatches; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in l pendants 7 and pendantarbors, so-ealled,

for watches, whereby the watch may be wound,

i the hands operated or set, and when the device is attached to a hunting-watch case the cover thereof may be opened.

My invention consists particularly in the method of maintaining` the pendant or winding arbor normally in position to actuate the winding mechanism. l Moreover, this arbor is spring-actuated when out of its usual normal position, and thus is compelled to return automatically to a fixed determinate place. An

outward or endwise movement oi' said arbor serves to engage and operate the handsetting devices, while an inward thrustof the pendant crown and arbor effects release of the casespring to open the cover in the event of my device being attached to a hunting-case.

Briefly stated, the operation of setting the hands is accomplished by the pendantarbor against the pressure of aspring-actuatedloose annular sleeve, while release of the case cover is eiiected bysaid arbor against the case-spring itself; hence by the arrangement of parts this loose sleeve compels the arbor to return to its normal position for winding the watch upon release of the pendant-crown, the latter, before such release, standing in its extreme outward movement in position for operating the hands. 'Thus it is evident that by no possibility, can the arbor be lettin the wrong position, as new sometimes occurs by carelessness or Oversight; otherwise it might be left on the hand-set connection, which would at once stop 5o the watch.

In the drawings, Figure jl. represents a central vertical section ot' a pendant and pend- (No model.)

In said drawings, A represents a portion of a stem-winding hunting-watch case, to which is secured a pendant, B, of any ordinary censtruction, and provided with the boreaforadmission of the arbor into and within the watch case proper. Furthermore, this is hollow or chambered at b, which is interiorly screwthreaded for a short distance at its outer end, or otherwise adapted to engage and receive a solid plate or button, d. This plate is centrally perforated to admit of easy passage through it of the arbor O, which is threaded at its extremity, and thus attached to the pendant-crown D. The pendant-arbor is shown as provided within the neck or contracted portion a of the pendant B with a collar, c, or this may represent the size et' the metal, which is reduced or turned down throughout its remaining portion.

Vithin the chamber b of the pendant B is placedA a loosely fitting tubular sleeve, E, which is somewhat shorter than the corre` spending internal dimension of the said pendant. This loose sleeve is closed at the end adjacent to the watchcase, with the exception of a hole through which the pendantarbor plays. The upper end is open, through which aeoiled spring, g, is introduced into the sleeve, and this spring is then reta-ined between the closed end of the latter and the plate ci, before mentioned as aiiixed to the end of the pendant.

By reference to the drawingsit will be seen that the loose sleeve is supported against the pressure of the spring g by the inner end of the pendant f, and thus no pressure is permitted upon the pendant-arbor-whenyin its normal position.

In Fig. 2 is shown the mechanism which n connects the pendant-arbor with the hand operating and winding parts. This consists ci a yoke-plate, F, and spiingactuated lever G, the yoke-plate carrying a pair of gears or toothed-wheels, h c', the former of which is adapted to normally engage with a toothedwheel, H, for winding the watch.

IOO

Thus the operation of my device is as follows, with the parts shown in their normal positions. As before explained, the springactuated sleeve prevents endwise movement of the arbor, except when desired, and thus' maintains it normally in action for winding the watch. In the event ol' a desire to actuate the hands, the pendant crown and arbor are drawn outwardly, the enlarged portion e of the arbor engaging with the under side of the closed end of the sleeve I,which is carried endwise against the tension of the spring g until it strikes the plate d. Simultaneously therewith the lever G is released by the endthrust of the pendant-arbor, and the gear is then meshed with the pinion I, carrying the post to which the hands are secured. Immediately upongthe proper adjustment of the hands the crown is released and the tension ofthe spring g again returns all the parts to their normal position. Thus the watch is always in condition to be wound, and there can be no liability of the user operating the hands in lieu of the winding mechanism.

At .I is shown the case-spring, and j is the catch thereof, since in the present instance I assume that the drawings represent a hunting-case.

One advantage derived from my present improvement is that the enlarged portion e of the pendant is retained between the catch j of the ease-spring and the closed end of the movable sleeve, which latter removes all pressure from the pendantarbor and the latter is easily turned by the crown D. The squared or soelieted end of the arbor projects through a slot formed in the casespring, as usual. Furthermore, the pendant-arbor is not only employed in its normal position to wind the watch, but by a slight outward pull can be changed into such position as to actuate the hand-setting mechanism; and, again, a third function of said pendant-arbor is to release the ease-spring catch from the cover of a hunting-case. This is easily accomplished by pushing the crown and pendant arbor inwardly until the enlarged portion, e, of the arbor strikes against and advances the casespring J inwardly,when the cover is released. rIllte reaction of said spring returns the pendant-arbor to is normal position.

In the event of employing a pendant winding and setting arbor of the above descrip tion with a heavy watch-case, it will be found necessary to move the pendant-arbor a greater distance inward in order to actively induce the ease-spring to release the cover; hence there is danger of advancing the extremity oi` the arbor, if formed of a single piece, too tar within the movement. To obviate any such difficulty I have constructed the pendant-arbor of two parte, (see Fig. 3,) wherein the squared part s of the arbor is spring-actuated. Thus, when the arbor has advanced as lar as is deemed expedient, this part s yields and retreats within the arbor proper, and thus permits the enlarged portion c to advance a suiicient distance to compensate for the greater movement oi` the case-spring required by the additional thickness of the case.

The mechanism for retaining the piece s is a pin secured to the part e, and engaging with a longitudinal slot eut in said part s, thus endwise movement of the latter is permitted, while its rotation is effected by the arbor proper secured to the crown D.

l. The eonlbinatiomwith thependant, pendant-arbor, and crown, ol' the loose spring-aetuated sleeve operating within and supported by the pendant, whereby all pressure is removed from the arbor while the latter remainsV in its normal position for winding, substatitially as herein described.

2. The crown and winding arbor, in com bination with the pendant B, the sleeve E within said pendant and surrounding said arbor, and a spring forcing said sleeve against the bottom or inner end ot' the pendant, said spring and sleeve exerting normally no pressure 0n said arbor, but preventing the latter from being` accidentally drawn back beyond a certain point, substantially as set forth.

3. In combination, the pendant, its loose spring-actuated sleeve, and the crown wit-h its arbor, all operating, as herein described, to return the arbor automatically to its normal position after operating the hands, substantiall y as stated.

et. The combination, with a pendant inclosinga loose spring-actuated sleeve, a pendant winding and setting arbor, of the case spring catch adapted to be actuated by said arbor, substantially as herein described.

5. A pendant winding and setting arbor provided with an enlarged portion, which shall engage a loose spring-actuated sleeve in the act of setting the hands, substantially as explained.

6. A pendant winding and setting arbor provided with a collar or enlarged portion, which shall normally remain free from pressure between a loose spring-actuated sleeve andthe case-spring, wherebyit is compelled to return to its normal position in the event ofendwise movement in either direction, substantially as explained.

7. A pendant-arbor composed of two parts, the inner extremity of one portion being eularged and recessed to receive and permit re# treat ot' the other, in combination with a spring in said recess for purposes explained.
