Specification of Letters Patent.

Application filed June 16, 1909.

To all whom it may concern:

Be it known that we, lVAL'rnn B. Mnnn and lViLIJAiM: H. Ennnnann, citizens of the United States, and residents of Waltham, in. the county of llliddlcsex and State of Massachnsetts, have made and invented certain he and useful Improvements in atches, of which the following is a specification.

Our invention relates to an improvement in watches, the object being to overcome certain dil'liculties heretofore experienced in the manufacture of watch movements, and more especially in the production of cheap or low grade movements, and further, to devise such improvements as will. lend to the completed watch better time keeping qualities, without in any way adding to the cost of production, and in fact, materially decreasing such cost.

A further object of our invention. is to give to a cheap watch all the appearances and advantages in time keeping qualities of a much higher grade and more costly move ment, and with these and other ends in view, consists in certain novel features of construction and combinations of parts, will be hereinafter fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a. watch movement con structed in accordance with our invention, looking at the train side thereof. Fig. 2 is a sectional view taken on the line 2*). of Fig. 1. Fig. 3 is a detached plan view of the pendant set mechanism looking at the dial side of the movement, and the parts in their winding positions. Fig. l is a sectional view of the pendant set mechanism in its winding position, and taken on the line l:-l of Fig. (3. Fig. 5 is a similar view showing the parts in the hand-setting position. Fig. 6 is a top end view showing the mechanism illustrated in F igs. l and Fig. '7 is a sectional view taken on the line 7-7 of Fig. 5, looking in the direction as indicated by the arrow. Fig. 8 is a sectional view taken on the line 88 of Fig. 4. Fig. 9 is a seetional view taken on. the line 9 9 of Fig. 5, looking in the direction as indicated by the arrow. Fig. 10 is a detached perspective view of the setting lever spring.

Heretofore in the construction of the higher grade, or more expensive watches,

the winding and setting mechanism has been so constructed and assembled that when it is desired to set the hands, the winding arbor or stem is pulled outwardly and automatically locked or held in such adjustment, whereby the setting train or pinions are brought into engagement with the hand setting pinions. After the hands have been set, the winding stem or arbor is then pushed inwardly, bringing into proper relative positions the winding mechanism. in the cheaper watches, however, it has been the practice to so construct and assemble the mechanism that in order to set the hands, it is necessary to push inwardly the winding stem or arbor, and to manually hold it in such position while the hands are being set, the spring being employed to return the winding stem or arbor to its normal or winding position.

One object of our invention is to substitute for this characteristic feature of the cheap watch, mechanism which. will operate in every way the same as that employed in the pull-out mechanism of the higher grade watch, and at a cost lower than that at which the cheaper mechanism has heretofore been produced, and in carrying out this feature of our invention, we employ a post 23, one end of which projects through an elongated slot 2% in the top plate 25, and has tightly secured thereto by means of the screw 26, the winding wheel 27, the opposite end of said post 23 projecting through the elongated slot 28 formed in the dial plate 29, and to which end is tightly secured by means of the screw 80, or otherwise, the setting wheel 31, the elongated slots 2 t and 28 formed respectively in the top and dial plates, permitting of a certain lateral movement of said post and its attached wheels or pinions, for the purpose hereinafter described. li ithin slots formed in the top plate 25, lit the edges of the two plates 32, 83, the opposite edges of said plates 32, 33, being formed with projecting lugs or ends 34- (Fig. 3), passing through openings formed in the dial plate 29, and between which plates is contained the winding pinion 35, the teeth of which extend through a slot in the top plate and mesh with the teeth of the winding wheel 27, as illustrated in Figs. 1 and 2 of the drawings.

In the plates 32, 33, employed for the purpose of retaining in position the winding pinion 35, are formed openings through which the winding arbor or stem 86 passes, the latter also passing through a squared opening formed in the winding pinion 35, and thereby adapted to turn with said arbor when the latter is rotated, as in the act of winding the movement or setting the hands. A portion of this winding arbor 3G is cut away, as illustrated at 87, (F'gs. at and Si, forming the upper shoulder 38 and lower shoulder 39, and in this recess or cut-away portion, fits one arm d0 of a bell crank lever, tulcrumed on the stud 'it, the extreme end of the other arm as hearing against the post 23.

4-3, formed integral with or secured to the plate a l, as clearly illustrated in Fig. 10, this plate being formed with the projecting ends or lugs 45 frictioned in holes or openings formed in the dial plate 29 to receive them, as illustrated in Fig. 9 of the drawings, the opposite end of said plate it fitting in a recess 4 6 formed in the top plate whereby said plate and integral spring are securely held in their proper positions.

From the foregoing it will be understood that when lilQWlHCliHg stem or arbor 36 is pulled outwardly, the arm 4-0 of the bell crank lever will strike against the shoulder 39, thereby raising said arm it). as illustrated in Fig. 5, and causing the end of the arm t2 bearing against the post 23, to force said post 23 to the opposite end of the elongated slot 28 formed in the dial plate 29, all as illustrated in Fig. 5. As the post 23 travels to the opposite end of the slots 28 and 2-1, it necessarily carries with it the winding wheel 27 and setting wheel 31 secured to said post, thereby taking the winding wheel 27 out of mesh with the ratchet wheel 4E7 and causing the setting wheel 31 to engage with the intermediate setting wheel $8. The parts are held in this hand-setting position by reason of the upper free end of the spring 4E3 snapping under the outer end of the arm etO of the bell crank lever, the parts being so held until pressure is exerted on the winding stem or arbor 36 to force the same inwardly into the normal position, as illustrated in Fig. 4e. As this winding stem or arbor 36 travels inwardly, the shoulder 38 resting against the arm l0 of the bell crank lever, carries said arm inwardly or downwardly, the curved outer end of said arm forcing the free end of the spring outwardly until the extreme end of said arm engages in the bend at) thereof. At the same time the extreme end of the arm d2 of the bell crank lever travels outwardly, or in a direction away from the post 93, the latter being caused to assume its normal position at the ends of the slots 28, 2%, by means of the spring 50, one

Engaging with the outer end of the arm 40 ot' the bell crank lever, is a spring end of said spring being partially wrapped around said post 23 and the opposite end around a pillar 51, as illustrated in Fig. 6. It will therefore be plain that by means oi these few parts, cheaply made and assembled, we have provided a movement with winding and setting devices of the type usually employed in high grade 'atches, and overcome the objections to that type oi? mechanism wherein it is necessary to force the winding stem or arbor inwardly in order to set the hands; furthermore, we have provided means whereby the winding stem or arbor is easily and readily attached to or detached from the movement. these means comprising the stud ll, one end of which, as illustrated in Figs. 6 and 8, is mounted in the dial plate 29, and on which stud is threaded the bell crank lever 4:ll2, the opposite end of said stud 1-1 being mounted in the top plate If the stud be turned or rotated in the plates 25, 29, the bell crank lever is caused to travel toward the dial plate 29, as illustrated in Fig. 8, that is, away from the reduced portion 37 of the winding stem or arbor 3G, permitting the shoulder 39 to clear the arm etO of said lever, and said arbor to be removed or detached from the movement. \Vhen the winding stem or arbor has been inserted into place, the stud l-l may be turned or rotated in the opposite direction, thercby causing the bell crank lever ll-5 2 to be brought in contact with the shoulder or enlarged portion of the stud, and also bringing the arm it) of the said lever into the groove or recess of the winding stem or arbor 36, as illustrated in Figs. 4c, 5 and G of the drawings. It will thus be seen that by the manipulation of this one stud ll, the winding stem or arbor is easily and quickly inserted into or removed from place.

Having fully described our invention, what we claim as new and desire to secure by Letters Patent, is

1. In a watch movement, the combination with a dial plate and top plate, oi a post laterally movable in elongated slots formed in said dial and top plates, and having the winding wheel secured at one end thereof and the setting wheel at the opposite end, a bell crank lever fulerumed between said dial and top plates, a winding arbor provided with a recess in which tits one arm of said bell crank lever. the opposite end of said lever engaging said laterally moving post whereby when said winding arbor is pulled outwardly, said post. with its attached wheels is caused to travel in one direction in said slots, a spring secured between said dial and top plates and engaging with said post whereby to return the latter to its normal position when said winding arbor is pushed inwardly, and aspring, one end of which engages the end of lv tit) one arm of said bell crank lever to hold the I will. be caused to travel into and out of enlatter in its ditlerent positions, substantially as described.
