To all whom it may concern.-

Be itkn own that LARCHIBAL'D BANNATYNE, of Waterbury, in the county of New Haven and State'of Connecticut, have invented a new Improvement in Stem-finding and Stem-Setting Watches; and I do hereby declare the following, when taken in connection with the accompanying drawings and the figures of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute'part of this specification, and represent, in

Figure 1, a View, partly in elevation and partly in section, looking at the outer face of the rear movement-plate of my improved watch with its segmental cap removed; Fig. 2, a view of the watch, partly in elevation and partly in Vertical central section, but showing only the winding and setting instrumentalities of the watch and some parts directly connected therewith; Fig. 3, a broken view, in inside elevation, looking at the coupling-head located upon the inner end of the winding and setting spindle; Fig. 4, a detached view showing the operating-spindle and the parts immediately associated therewith; Fig. 5, a sectional viewshowing the construction and arrangement of the inner and outer intermediate Winding-pinions; Fig. 6, a detached plan View of the spring of the operatingspindle; Fig. 7, a detached reverse plan view of the winding-pinion, showing its coupling-hub and the coupling-notches therein; Fig. 8, a detached perspective viewof the bridge in which the said pinion is mounted; Fig. 9, a detached view showing the mode of staking the main winding-wheel to the Winding-arbor; Fig. 10, a detached plan view of the segmental cap; Fig. 11, a detached reverse plan, view thereof; Fig. 12, a detached view showing a modified form of the parts represented by Fig. 4; Fig. 13, ayiew showing a modified form of the parts illustrated by Fig. 3; Fig. 14, a detached plan view of the modified coupling-head shown in Fig. 12; Fig. 15, a broken View of the front movement-plate to show the elongated clearance slot or opening formed therein for the ratcheting back of .the inner and outer intermediate windingpinions; Fig. 16, an enlarged sectional view through the rear and front movement-plates and through the. main arbor, the main winding wheel, the main time train -wheel, the mainspring, and the barrel inclosing the latter, together with a sectional view of the cap, which is lifted as preparatory to the removal of the said arbor and wheels without disturbing the front and rear movementplates.

lWIy invention relates to an improvement in stem-winding and stem-setting watches, the object being to produce a simple, durable, and reliable mechanism constructed with particular reference to reducing the number of parts to the minim um and to constructing and arranging those parts so as to avoid their derangement or breakage.

With these ends in view my invention consists in certain details of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I provide the crown 2 with a rotatable and longitudinally-movable Winding and setting spindle 3, mounted in the pendant 4, which carries thering 5 and which is secured to the ring-like central portion 6 of the watch case. A spiral spring 3, also located within the pendant 4, coacts with the said spindle,

so as to normally hold it at the limit of its outward movement. The projecting inner-end of the said spindle is furnished with a coupling-head 7, formed with a diametrically-arranged coupling slot 8, which receives a coupling-key SJ, formed integral with and extending directly upward from a setting-pinion 10, itself formed integral with the upper end of a longitudinally-movable and rotatable spindle 11, virtually constituting a continuation of the winding and setting spindle 3, with which it is arranged in line. For the sake of convenience I shall call this spindle 11 the operating-spindle. It will be understood that when the watch-movement is inserted into the watchcase the key 9 will be entered into the coupling-slot 8 of the coupling-head, whereby the two spindles will be coupled together, so that the rotation of the former will be .communicated to the latter.

A fiat sheet-metal spring-12, having ahead 13, is mounted between the front and rear movement-plates 14 and 15 of the watch, in a plane at a right angle to the planes thereof, in position for the engagement of the extreme end of the spring with the extreme lower end of the operating-spindle, which the spring exerts a constant effort to normally maintain at the limit of its longitudinal outward movement. For the purpose of being so mounted thehead 13 of the spring is formed at its opposite ends withlugs 13 13, which are entered intosuitable openings 13 formed in the plates l t and 15 aforesaid. The spindle 11 is provided below its longitudinal center with a coupling-pin 16,driven transversely through it and adapted to have its ends entered into the respective notches of two pairs of coupling-notches 17, formed in a coupling-hub 18, made integral with the lower face of the winding-pinion 1%,, through which the spindle 11 passes and in which it is free to have longitudinal movement, and in which it is also free to have rotary movement when it is pushed inward so as to clear the ends of thecouplingpin 16 from thenotches 17 of thehub 18. The said winding-pinion 19 is journaled, with a capacity for rotation, in a single sheet-metal bridge 20, located near the pendant 4 and at a right angle to the movement-plates l4 and 15, in which it is mounted, being constructed for that purpose withlingers 21, 22, and 22, formed upon its opposite edges and entered into suitably formed and arrangedopenings 22*, formed in the said mo vement-plates. For the purpose of mounting the winding-pinion 19 in the bridge itis constructed with an upwardly-projecting bearing collar or bushing 23, the edge of which bears upon the walls of a circular bearing-opening 24;, formed in the bridge, as clearly shown in Fig. 2. This collar terminates in aflange 25, engaging with the upper face of the bridge, as also shown in Fig. 2, whereby the winding-pinion 19 is held in place, but left free to rotate.

Normally the operating-spindle 11 will be held at the limit of its outward longitudinal movement through the medium of the operating-spindle spring 12, already described. At this time the ends of the coupling-pin 16 will be entered into a pair of thenotches 17, whereby the spindle 11 will be coupled with the winding-pinion 19, which through the medium of the said spindle will also be coupled with the winding and setting spindle 3, the turning movement of which in either direction will be transmitted to the winding-pinion l9.Thesaid pinion 19 is constantly in mesh with an innerintermediate windingpinion 26, bearing against the inner face of the inner movement-plate 15 and formed with a long outwardly-projeotinghollow hub 27, passing through an elongated slot or clearance-opeding 28, formed in the saidplate and permitting the hub to move back and forth in discharging the function known in this class of mechanisms as ratcheting back. The projecting outer end of thehub 27 has rigidly mounted upon it an outer intermediate winding-pinion 29, larger in diameter than thepinion 26 and bearing against the outer face of the movement-plate 15 and normally kept in mesh with the main winding-wheel 30 through the medium of aspring 31, secured to the inner face of theinner plate 15 and engaging with the innerintermediate pinion 26, as shown in Fig.1. Then the crown 2 is turned from right to left in the normal position of the parts of the winding and setting mechanism, theintermediate pinions 26 and 29 will be moved from right to left in theelongated slot 28, so as to carry the teeth of thepinion 29 into full engagement with the teeth of the main winding-wheel 30, which will then be rotated in winding the mainspring, which is not shown; but when the crown 2 is turned from left to right thespring 31 will yield and permit the intermediate winding-pinions 26 and 29 to move from left to right within the limits of the length of theelongated slot 28, in which thehub 27 has lateral as well as rotary movement, as already described. This movement of thewheels 26 and 29 from left to right permits the teeth of thewheels 29 to clear the teeth of the main wheel, whereby the function of ratcheting back is accomplished.

As clearly shown in Fig. 2, the setting-pinion 10 normally clears the intermediate setting-pinion 32, mounted upon the outer face of the front movement-plate 14- upon astud 33. The saidpinion 32 is constantly in mesh with a minute-wheel 34:, which is also constantly in mesh with the cannon-pinion 35, the said wheel 31- and cannon-pinion 35 being located upon the outer face of the front movement-plate 1'4. (Shown in Fig. 2.) Normally the rotation of the wii'iding and setting stem 3 has no effect upon thepinion 32, thewheel 34, and the cannon-pinion 35, inasmuch as the setting-pinion 10 is normally out of mesh with thepinion 32. \Vhen, however, it is desired to set the watch, the spindle 3 is forced longitudinally inward by pressure upon. the crown 2 against the tension of its own spring 3 and against the tension of theoperatingspring 12 of the operating-spindle 11, which is forced inward at the same time, whereby thesettingpinion 10 is brought into mesh with the intermediate setting-pinion 32, and whereby also the ends of the coupling-pin 16 are pushed out of engagement with thenotches 17 in thehub 18 of the winding-pinion 19. Now when the spindles are rotated in either direction through the medium of the crown 2, the setting-train, including thepinions 10 and 32, thewheel 34;, and thepinion 35,will be actnated,without,however,disturbing the winding-train, for the reason that tho operating-spindle 11 will rotate inside of the winding-pinion 10 and its bearing collar or bushing 23. Whenthe watch has been set,

the inward pressure upon the crown 2 is removed, permitting thesprings 12 and 3 to reassert themselves in moving both spindles outward, whereby the setting-pinion 10 is disengaged from the intermediate setting-pinion 32, and whereby the ends of the coupling-IIO pin 16 are entered into a pair of thenotches 17 in the coupling-hub 18 of the winding-pinion 19, leaving the watch again in its normal adjustment for winding.

The main winding-wheel 30 is staked directly onto the inner end of the winding-arbor 36, which for this purpose is formed with ashoulder 37, located adjacent to the inner trunnion 38 of the arbor, the said trunnion having hearing in abearing opening 39, formed for its reception in asegmental cap 40, the inner face of which is formed with arecess 41 to receive thewheel 30 and also with arecess 42 to clear the outer intermediate winding-pinion 29, the main winding-wheel pawl 43, and thespring 44 thereof. The rear movement-plate is cut away, as at 15, for the reception of the rear end of the drum which receives the mainspring, and which is shown by broken lines in Fig. 1, this opening 15 being spanned, as it were, by thesaid cap 40. The saidbarrel 30 is rigidly connected with the main time-train wheel 30 which is mounted so as to turn freely upon themain arbor 36, the forward end of which is formed with atrunnion 36, having bearing in the front movement-plate 14. The outer end of thespring 44 is connected with thebarrel 30, and hence with themain timetrain wheel 30 It will be seen from the foregoing description that the main windingwheel 80, the main time-train wheel 30", thebarrel 30*, and the mainspring 44 are all organized with themain arbor 36, so as to form, in a sense, an independent organization,which may be introduced into and removed from the watch-movement through theopening 15 in the rear movement-plate without being in any way dismembered, even to the removal of the main winding-Wheel 30. For the purpose, however, of introducing or removing this organization the cap must be removed; but that is a simple matter. The construction just described secures a marked economy of space and affords protection for the parts just mentioned, the cap being secured in place by screws passing through its screw-holes 45 and 46.

Instead of employing a coupling key 9, formed integral with the setting-pinion 10, I may, if preferred, provide the upper end of the spindle 11 with acollar 47, furnished with a coupling-pin 48, as shown in Fig. 12, and form the coupling-head 7 of the Winding and setting spindle 3 with aradial slot 49 for the reception of the said pin. Instead also of providing the operating-spindle 11 with a coupling-pin 16 I may provide it at its lower end with ahead 50, formed with a pair of coupling-lugs 51, arranged to enter the coupling-slots 17, formed in thecollar 18 of the winding-wheel 19.

In view of the modifications suggested and of others which may obviously be made, I would have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within thespirit and scope of my in vention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
