ELIAS B. DOUGLASS, OF CORTLAND, INDIANA.
STEM WINDING AND SETTING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 325,594, dated September l, 1885.
(No inodc'.)
To @ZZ whom t may concern:
Be it known that I, ELIAS B. DOUGLAss, a citizen of the United States, and a resident of Cortland, in the county of Jackson and State of Indiana, have invented certain new and useful Improvements in Vinding and Setting Mechanism for W'atches; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention has for its object the production of a combined winding and setting mechanism for stem-winding watches, whereby the watch may be set, as well as wound, by the same cap, thus dispensing entirely with the necessity of opening the watch, and avoiding the entrance into the same of dirt and moisture, while at the same time the watch may be more easily and rapidly set than by the old method.
To these ends my invention consists in the improved construction and combination of parts, which will be hereinafter fully de scribed, and particularly pointed out in the claims.
Referring to the annexed drawings, Figure l is a perspective view of a stem-winding watch provided with my improved n1echanism, portions of the watch-casing being removed to better illustrate the construction and arrangement of the various parts., Fig. 2 is a top view, with the winding cap shown in dotted lines. Fig. 3 is a perspective top view, with the winding-cap and adjusting-ring removed and portions ofthe watch-casing broken away. Fig. 4 is a sectional view taken on line x rr, Fig. 2; and Figs. 5 and 6 are detail views, in perspective, of parts of the mechanism which will be hereinafter described.
The same letters of reference indicate corresponding parts in all the figures.
Referring to the several parts by letter, A A represent the plates or casing between which the operative mechanism of the watch is placed, the said mechanism proper being of ordinary construction. To the outer casing, A, is centrally pivoted, at the point shown, the plate or yoke B, having pivoted upon it at its center the gcarwvheel C, adapted to mesh with the teeth of two pinions, C' and C2, pivoted one at each end of the plate B, as shown. The teeth of the wheel C also mesh with the teeth of a pinion, D, which is mounted upon a spindle or shank, D', having a central vertical aperture, D, square in crosssecti'on, in which the lower square end of the cap-spindle or stem E' fits, the pinion D being rotated by turning the cap E in the usual manner. One of the pinions, C', on the plate B is adapted to mesh with the teeth of a cog-wheel, F', on thc mainspring-shaft F, a spring, Gr, normally holding the said pinion in contact with the said cog-wheel, and when the plate B has been thus adjusted by turning the cap E the watch will be wound through the intervening mechanism just described. The other pinion, G2, on the plate B is adapted to be put into connection with the hand-setting mechanism (which is of the usual construction) through the intervening cog-wheels, H H', when the plate B has been swung to that side through thek intervening mechanism, which will be now described.
The upper part of the watchcasing is formed with the annular shoulder I, having the upward projections l' I', and the central aperture, I2, through which passes thc hollow shaft J. This shaft .I is formed at its upper end with the'wings J', extending at right angles thereto, and adapted to fit movably between the upward projections l' when in its operative position. The lower end of this hollow shaft J is provided at a point inside of the watclrcasing with the arm J2, extending at right angles thereto, and provided near its free end with a vertical aperture, j, in which fits movably the upper free end of an upwardly-projecting arm, B', formed on the plate B, near the center of the saine, as shown.
To the upper end ot' the hollow shaft J is attached the adjusting plate or ring K, which is ot' the form shown, and is provided with the down wardly-proj ccting pin l', adapted to enter either one of two small apertures, I3 I", in the upper surface of the annular shoulder I, the adjusting-ring being capable of being slightly raised to disengage its pin from either of the holes in which it is at the time resting, and to adapt the ring to be turned so as to in` sert the pin into the other aperture, for the purpose which will be hereinafter set forth, a
IOO
. D, as before mentioned.
Normally, the pin K of the adj Listing-ring rests in the aperture l, thus bringing the pinion C in contact with the cog-wheel F ofthe mainspring-shaft, so that by turning the winding-cap the watch will be wound through the intervening` mechanism previously described. Vhen, however, it is desired to set the hands of the watch, it is only necessary to raise the adjusting-ring sufficiently to clear its downwardly-projecting pin from the hole in which it is then resting, when by turning the said ring to the left the pin may be inserted in the other aperture, I, this movement of the adjusting-ring turning the hollow shaft J, and consequently the arm on its lower end in the same direction, and thus operating, through the upwardly-projecting arm B ofthe plate B, to swing the said plate on its pivotal point until the pinion C2 comes in Contact with the cog-wheel I-I, when by turning` the windingeap the hands of the watch can, through the intervening mechanism previously described, be readily and easily set.
From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of my improved mechanism will be readily understood without requiring further explanation.
It will be seen that my improved mechanism is simple in construction, being devoid of complicated parts,which are liable to break or get out of order, while at the same time it is very efficient in its operation. By its use the necessity for opening the watch iu order to set the hands is entirely obviatcd, thus preventing the entrance of dust or moisture.
The cap E screws down after winding or setting the watch in the usual manner, thereby preventing the entrance of dust into the watch.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-
l. As an improvement in stem winding and setting watches, the combination of the pivoted yoke having the gear-wheel and end pinions, and formed with the upwardly-projecting arm, the winding-stein having the pinion at its lower end, and the hollow shaft provided at its lower end with the operating-arm, and having at its upper cud the adjustingring provided with the retaining-pin, all constructed, combined, and arranged to operate in the lnanuer and for the purpose shown and set forth.
2. As an improvement in stem winding and setting watches, the combination of the pivoted yoke having the gear-wheel and end pinions, and formed with the upwardly-projecting arm, the spring for holding the yoke normally in contact with the cog-wheel on the end of the mainspring-shaft, the windingstem having the cap at its upper end, and provided at its lower end with a pinion, and the spring-actuated hollow shaft provided at its lower end with the operating-arm, and having at its upper end the adjusting-ring provided with the retaining-pin, all constructed, combined, and arranged to operate in the manner and for the purpose shown and set forth.
3. As an improvement in stem winding and setting watches, the combination of the pivoted yoke having the gear-wheel and end pinions, and formed with the upwardly-projecting arm, the winding-stem having the pinion at its lower end, the annular shoulder formed on the upper side of the watch-case and having the upward projections, and the hollow shaft provided at its lower end with the operating-arm, and having at its upper end the adjusting-ring provided with the retaining-pin, all constructed, combined, and arranged to operate in the manner and for the purpose shown and set forth.
et. As an improvement in stem winding and setting watches, the combination of the pivoted yoke having the gear-wheel and end pinions, and formed with the upwardly-projecting arm, the spring for holding the yoke normally in contact with the cog-wheel on the end of the mainspriug-shaft, the windingstem having the pinion at its lower end, the annular shoulder' formed on the upper side of the watch-case and having the upward projections, and the spring-actuated hollow shaft provided at its lower end with the operating-arm, and having at its upper end the adjusting-ring provided with the retainingpin, all constructed, combined, and arranged to operate in the manner and for the purpose shown and described.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
