STEM W'iNlNG N SETl'lNG lrV/iTCl-li SPECIFICATION forming part of Letters Patent No. 392,580, dated November 6, 1888.

Application filed Nay 5, 1388. Serial No. ilill. (No model.)

To aZZ whom it may concern.:

Be 1t known that I, GASPAR Krsrnnn, a citi-- `zen of the United States, residing at Sterling,

in the county of "Whiteside and State of Illinois, have invented certain new and useful Improvements in Pendant Setting and TVinding IVatches; 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 figures of reference marked thereon, which form a part of this specification.

My invention has reference to certain improvements in pendant winding and setting watches, and pertains more especially to mechanism for optionally communicating the motion from the winding-pinion to the winding mechanism and setting mechanism, respectivel y, and for disengaging the outer and intermediate winding mechanism from the works when such works are removed from the ease, and therefore not controllable from the winding-stem.

In reference to the first part of my invention-that of alternately and optionally connecting the winding-stein to the winding mechanism and the setting mechanism-my invention relates to certain novel mechanism for placing and holding the usual oscillating yoke, which carries the intermediate winding-wheel and intermediate setting-wheel at its opposite extremities, in such position that said intermediate wheels may be optionally thrown in or out of engagement.

It is well known that the works of watches are sold and handled and regulated largely outside ofand independent of any special case. ,Vhen the yoke above referred to is controlled wholly from the winding-stem, such works are uncon` trollable when removed from the case, and, the intermediate setting-wheel being normally in engagement with a pinion which receives rotation from the hand-wheels, the running of the works, when separate from the case, involves the movement also ofthe main windingwheel and winding-pinion and the intermediate winding and setting wheels. This is more mechanism than the mainspring is required to operate when the works are in the case, inasmuch as in the latter situation the windingstem is utilized to hold the intermediate setting-wheel out of engagement with the handwheels. Therefore it frequently results that when the works have been regulated independent ofthe case and are subsequently placed in the case the less work required of the mainspring in the latter situation results in the watch running at a greater velocity.

In the drawings, Figure l a view of the front side of the ordinary pillar-plate ofa watch provided with my invention, a portion ofthe case and said plate next the windingstem bcing cut away to more fully illustrate the posi tion and operation of my devices. Fig. 2 is a view of the opposite side of said pillar-plate, showing the location of the bell-crank lever S, one end of which is projected through the winding-pinion in position to be oseillated inward by end pressure from the winding-stem. Fig. 3 is a detail of the lever S. Fig. el is a detail of the rim of the case, showing the location and mode of seating the forked oscillating lever 9, the fork of which bestridcs the usual annular recess in the winding-stem. Fig. 5 is a detail of saidlever 9. Fig. G is a detail of a section of the outer edge of the pillar-plate, showing the location therein of the spring-lever 10. Fig. 7 is a pian view showing (enlarged) the oscillating yoke and parts adjacent thereto.

XVhen the works are in the case, the springlever l0 permits the curved spring ll to rise to the upper smaller portion ol" the lug l2 on lever S, in which condition said lug is withdrawn from contact with the adjacent end of the yoke 4., and the curved spring 13, inserted in said yoke near the intermediate windingwheel, draws that end of the said yoke inward and disengages the intermediate setting-wheel; but when the works are in the case the latter forces the outer end of the short lever 10 upward, and thereby forces the spring ll down behind the larger portion of the lug l2, when the adjacent end of said yoke is thrown inward'and the intermediate setting-wheel controlled from the winding-stem, as hereinafter stated.

l is an ordinary watch-case.

2 is the pendant, in which is longitudinally loosely seated the winding-stem 3.

e is the usual oscillating yoke, carrying at one end the usual intermediate winding-wheel, 6, and at the other end the intermediate setting-wheel, 7, and under said yoke is centrally pivoted the usual main winding-wheel, 25.

8 is a bell-crank lever suitably pivotcd at IOO its vangle to the pillanplate 11 near the edge ofthe latter, and has one of its arms projected inward and furnished with a post or lug, 12, which latter is projected through said pillarplate in position to be forced to or from the adjacent end of the yoke 4.

9 is a slightly-curved lever, (see Fig. 5,) which is centrally pivoted on the rear side of the front flange of the case center and near the opening in said case, through which the winding-stein 3 is projected, and in such relation to the latter that the forked end 1.5 of lever 9 bestrides the stern fitting into theusual annular recess, 16, formed in said windingstern. The movement in and out of the winding-stem 3 imparts oscillation to the lever 9 about in the plane of the rear side of the pillarplate 111-.

17, Fig. 4, is the pivotal seat of lever 9, and is a screw set in the ease 1 from the rear.

19, Fig. l, is a short post formed on the rear side of the front flange of case 1 in such relation to the adjacent end of lever 9 as that said end of said lever in its oscillations passes over post 18, and is held by the latter at the differcnt ends of the arc of oscillation of said lever.

The lever 9 is reduced in thickness near the end adjacent to post 1S, which permits said end to spring slightly in passing over post 1S. The outer side of the post 18 has a beveled formation, and the outer side of the adjacent end of lever 9 is also beveled, such beveled ends assisting, respectively, the adjacent end of said lever to rise over said post in each direction.

The purpose ofthe lever 9 and post 1S is to limit the inward and outward movement of the windingstem 3 in changing the position of the latter from winding to setting, and vice versa, and also to hold said stern at the limit of its in and out thrusts, and particularly to prevent said stem from working outward during the process of winding. The forked end of the lever 9 may also abut against the wall of the case 1 in the outward throw of said forked end. rlhe back of the cavity in the crown of the windingstem abuts against the end of the pendant and also limits the inward thrust of said stem.

The bell-crank lever S is pivotally seated against the side of the pillar-plate 1-fi,and one of its arms, 19, is projected along the rear side of said plate to a point opposite tothe central opening in the winding-pinion 20, and said arm 1.9 is there bent at a substantially right angle outward and extended wholly through the windingpinion 29 in position to be pushed inward by the inward thrust of the windingstem 3. The other arm, 21., of lever S is projected inwardly from the pivotal seat of said lever, as aforesaid, along the rear side of plate 14, and there is there formed on the front face of said arm a lug, 12, which projects through said pillar-plate and lies against the outer side of a lng, 22, formed on the adjacent end of said pillar-plate. The lug 12 is formed with an outward shoulder, 5, near its base, against which shoulder the free end of' the curved spring 11 rests when the windingstem 3 is drawn outward, in which position the spring 11 forces the lug or post 12 against the adjacent end of the yoke 4 and thrusts such end inward, carrying the intermediate settingwheel into engagement with the pinion 23, adapted to engage the usual hand-wheel, the latter not being shown.) i In the construction shown in Fig. 1 a pinion, 23, is used between the intermediate setting-wheel, 7, and the hand-whcel; but theintermediatc scttingwheel, 7, can as readily be adapted to engage directly with one of the hand-wheels, as is'very frequently the case.

then the winding-stem 3 is pushed inward, its i nner end presses against the outwardlypro jeeting end of arm 19 of lever 8, and by the oscillation of lever 8 throws the opposite end of said lever outward, carrying the lug or post l2, and with it the spring 11, outward, so-as to release the adjacent end of yoke et from outside pressure, in which condition the usual spring, 13, acting on the opposite end of the yoke-1, draws said end inward and the intermediate winding-wheel into engagement with the winding-ratchet; lout the-spring 11, being stronger than spring 13, the spring 1.1, when permitted to rest against its adjacent end of said yoke 4, will force such adjacent end inward notwithstanding the resistance of 'said spring 13 at the opposite end of said yoke.

A short post, 22, formed on the front side of' the pillar-plate near the free end of the spring ll and on the inside of the latter, serves to limit the inner movement of said spring when the winding-stem is drawn out and said spring permitted to throw the intermediate setting-wheel into operation. The post or stop 22 prevents the free end of spring 1 1 from pressing against lug 12 beyond a certain amount, and thereby prevents too great pressure of the intermediate setting-wheel upon the pinion with which it engages.

rlhe spring 11 is so formed and seated as that its free end if unresisted would rise on lug 12 abovethe shoulder 5 thereof and rest against the apex or smaller upper portion of saidlug, in which position the spring 13 at the opposite end of yoke 1 would draw its adjacent end of said yoke inward and disengage the intermediate setting-wheel. This is the condition when the works are separate from the case, and therefore said works may be regulated independently of the case and disconnected from the yoke i and its adjacent mechanism, andin precisely the same situation and condition in which said works will be required to operate. In order to control this upward tendency of the free end of the1 spring 11 when the works are in the case, and to compel said spring to remain in contact with the shoulder 5 of lug 12 on lever S, I provide a radial lever, 10, piv oted centrally on the front side of the pillarplate 1l, with its inner end resting upon the upper side of the free end of spring 11 and its outer end in position to be engaged and forced IIO upward by the adjacent llange of the case l. when the works are placed in the ease. The upper forcing of the outer end of lever 10 of course forces the inner end of said lever downward and presses and holds the free end of spring 11 down behind and in contact with the shoulder 5 on lug 12, and junction being now formed with the winding-stem, the intermediate setting-wheel can be disengaged through the medium of said stem; but when the works are removed from the case or before they are placed therein the inner end of lever 10 is free to rise with the upward pressure of spring 11, and thereby permit the latter, as aforesaid, to rise to the smaller portion of lug 12 and permit the disengagement of said intermediate settingwheel by the inward draw of the spring 13.

As the residue ofthe watch not specially described herein consists of the usual and wellknown parts, I do not deem it necessary to show or describe the latter.

Then my invention is used on hunting-case watches, the inner end of stem 3 is projected through the usual shoulder on said stem actuates said spring.
