HENRY MAYO HAINES, OF \VALTHAM, IvlASSi LGHUSETTS.
STEM WINDING AND SETTING MECHANlSiwl LLPECEFICATEQI'F forming part of Lett F0 a WATCH es.
Patent No. 308.,09, dated ETovember 25, 188%.
Application filed A pril i7, lrSl. (X0 model To aZZ 1072 0172, it may concern:
Be it known that I, HENRY M. HAINES, ot XValtha-m, county of Middlesex, State of Massachusetts, have invented an Improvement in \Vatches, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the d rawings representing like parts.
My invention, relating to stem winding and setting watches,is intended as an improvement in watches of that class in which the stem act uates a gear or toothed wheel, which in turn actuates other toothed wheels supported on a movable plate or swinging yoke operated by a shifting-lever, by means of which one or the other of the latter wheels may be placed in position to actuate the mainspring windingshaft or the hands, according as it is desired to wind or set the watch.
The invention consists, mainly, in a novel construction of the devices by which the hands are engaged, and of the shifting-lever, and in the combinatiomwith the said lever and mechanism controlled by it, of a locking device ("or holding the said lever in its diiferent positions,
the object of such novel construction beingto at't'ord increased convenience and certainty in operatiomas well as greater convenience in assembling the parts in the watch.
Figure l is a plan view of a watch containing winding and setting mechanism embodying my invention, the shifting-lever being in contact with the yoke and locked, with the winding mechanism out of engagement and the setting mechanism in engagement. Fig. 2 is a similar view showing the winding mechanism in engagement and the setting mechanism out of engagement.
In the annexed drawings, it represents the ordinary bevelpinion, with which the stem (not shown) of the watch is connected, and which engages the bevel-gear a, loose on the huh I), carrying the yoke 13. arranged above or outside of the bevel-gear, (also not shown,) the said yoke having the winding intermediate c, meshing with the gear a, and when the yoke is in its normal position, as shown in Fig. 2, also meshing with the mainspringgear 0 to complete the train of mechanism from the stem to the mainspring-shait,whereby the Winding of the mainspring is effected. The usual pawl, c, actuated by a spring, 0",
engages the mai nspring-gear 0 to prevent backward movement thereof, and the yoke 13 has an arm, 2, which extends beyond the winding intermer'liate to engage a stud, 3, and limit the inward mcvement oi" the yoke when the wind ing mechanism is thrown into engagement, as shown in Fig. 2. Iiiotiou is transmitted from the gear a, loose on the hub Z), to the minutehand shai't by means oi two intermediate or toothed wheels, (5 (1, arranged one above the other, and connected to rotate together on a common arbor or journal, which is support ed in an extension oi the yoke 13 on the opposite side to that carrying the winding intermediate 0, the upper or outer intermediate, (l, meshing with the gear a, and the lower or inner intermediate, (1, having pointed or V-sha ed teeth to engage similar-shaped teeth on the disk 0, fixed on the minute-hand or cannon-pinion a. The V- shaped teeth i'acilitate the engagement of the intermediate (1 with the disk 0 when it is desired to throw the setting mcelmnism into engagement, as will be presently indicated, and produce no jumping or turning of the hands when thesetting mechauisuris thrown into or out oi engagement therewith. Theyokell is loose on its hub, and normally the winding mechanism is retained in engagement and the setting mechanism kept out of engagement (see Fig. 2) by means of a spring,- secured to the frame, and hav ing its free end engaging a pin, f, fastened to the yoke, as indicated in the drawings.
To reverse the position of the parts, or throw the winding mechanism out of engagement and the setting mechanism into engagement, I provide shifting-lever, ii, pivoted at 11, and constructed substantially as shownthat is to say, substantially of Z i'ormthe arm '5 thereofpassi ng through the side or rim of the frame, to enable it to be caught by the operator and drawn outward to bring the other arm, ,into engagement with a projection, 4-, on the yoke B, and cause said yoke to swing or partially rotate on its hub,whereby the winding intermediate will be withdrawn from engagement with the mainspring-gear O to disconnect the winding mechanism, and the inner intermediate (1, having the v'shaped teeth and journaled to the opposite end of the yoke, will be I brought into engagement wit-h the toothed disk 0 on the minute-hand arbor, when the setting mechanism will be in condition to be opyokeactuating spring causes the projection et erated, all as fully shown in Fig. 1. The arm 2' of the shitting-lever is rigid, and, in acting on the projection t of the yoke or plate .lhturns the said yoke positively tor a definite distance sufticient to engage the teeth of the disk 0 and intermediate d, without, however, pressing the teeth together, so as to bring a lateral strain on the arbor that carries thehands, and the shitting-lever is easily op rated, as it has but slight force to overcome. A spring, 7;, formed in the present instance in one piece with the spring f, has a V-shaped projection, 7;, on its end, to engage the pin, 7F, on the under side of the lever i and hold said lever in engagement with. the projection on the yoke B, as shown in Fig. 1, whereby the p: rts are locked in such position until it is desired to again put the winding mechanism into position to operate, which is :mcomplished by pressing on the arm t to disengage the lever from the projection on the yoke, the pin 7. sliding over the projection 71; on the spring 7;, when the springf will cause the yoke to move on its hub, as stated, to engage the winding intermediate with the mainspring-gear. When the parts are in the normal )tlSlldOll shown in Fig. 2, the minutehand shal't,with its toothed disk, may be removed from the frame without disturbing the described winding or i-ietting mechanism, the two intermediates d (1 being sufficiently withdrawn from the disk on the minute-hand arbor to readily permitsuch manipulation of the parts. The pinion a on the minute-hand arbor engages with train for imparting movement to the houuhand,which is not herein shown. The setting-disk c is securely fastened to the minute-hand arbor or cannoirpinion a, and the setting intermediates (1 d are also securely fastened or staked together, so that they rotate as a single piee By having the two intermediates (ii (l the former may have line-pointed teetlnwhich are easily brought into engagement and operate more perfectly than a single intermediate adapted to engage both the actuating-gear a and a pinion or toothed wheel on the minutehand arbor.
(treat dil'ticulty has heretofore been e.\'pe rieneed in setting mechanism applied to watches on account of the ".nnping or move ment of the minntehand upon connecting the setting mechanism therewith to set the hands. To eti'ectively overcome this di'l'ticulty l propulled out to move the swinging yoke. The
on the yoke to be closely pressed or held against the inner arm of the shitting-lever as locked by too lockingspring, whereby I. am enabled to attain a hill and delicate engage ment of the setting intermediate with the setting-disk of the minute-hand arbor, wherein the teeth of the pinion are prevented from bottoming in the teeth ot' the setting-disk. ]l' the pinion and disk were brought into close contact, so that the teeth of the one bottomed in those of the other. roughness of action between the two would take place, and would show itself in the jumping ot' the minute-hand when the setting mechanismwas broughtinto engagement with the minute hand arbor. Further, it is important that the lever should be securely locked al'ter having been brought into engagement with the projection t of the yoke; otherwise by the action of the yokeactuating spring the lever would be caused to slip from the projection ":L, and thus throw the parts out of engagement. "Without the locking-spring the lever would have to be of such increased length as to force the setting intermediate and disks rigidly together in order to make the lever hold on the projection 4-, and the consequence of this would be a jumping oi the hands when the setting mechanism was thrown into as well as out of engagement with the minute-hand arbor.
l elaim- 1. 'ihe combination, substantially as de scribed, ot' the swinging yoke provided with a projection. -:t, the spring f, engaging said yoke, the actuating-le er, substantially of 2 form, with one arm adapted to engage the projection on the yoke, and the other arm passing the rim of the frame or casing, and the spring 7:, having the protection In, adapted to engage the pintfon the underside of the lever, for the purpose set forth.
2. The ininnte-haiul arbor provided with a toothed settingdisk, and the actuating-gear and swinging yoke provided with a setting intermediate, combined with the shitting or actuating lever adapted to engage the said yoke and move it a detinitedistance, and the spring with a V-shaped projection co-operating with the said lever, substantially as described.
in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
