STEM-WINDING WATCH.
:SPECIFICATION forming part of Letters Patent No. 723,123, dated March 17, 1903.
Application tiled June 2, 1902. Serial No. 109,834. (No model.)
To all whom, it 71mg/ concern,.-
Beit known that I, ANDERS AUNE, of Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in'Watch-Setting Attachments, of which the following is a specitication.
This invention relates to stem winding mechanism for watches, and has for its object the production of a simple, compact, and ornamental mechanism, all the parts of which may be mounted upon one side of the front plate of the watch-movementand which will provide for positively holding the clutch when in gear with the setting-train, so that if any member of the latter should be tight there will be no liability of the resulting friction causing a slipping of the clutch.
To these ends the invention consists in the construction and combination of parts substantially as hereinafter described and claimed. Y
In the drawings, Figure l represents a plan of my improved mechanism and of so much of a Watch-movement as is necessary to illustrate the adaptability and the operation of the invention, the parts being in position for setting. Fig. 2 represents a similar view with the parts in position for winding.
Similar reference characters indicate similar parts in both the figures.
The front plate of the watch-movement is indicated at a, and said plate supports the winding and setting mechanism, as hereinafter described. The arbor b, having a square portion b for the sleeve, is provided with the usual crown c and has its inner end or head b2 adapted to operate the sleeve-shif tin g mechanism, as will presently appear. The pinion for the winding-train is indicated at d and is provided with teeth CW, adapted to mesh with the teeth e' at the outer end of the sleeve e, said sleeve having teeth e2 atits inner end and a peripheral groove e3.
All of the parts so far described are or may be of an ordinary construction, as indicated in the drawings.
It is to be understood that in practice the arbor b will be suitably supported in a bearing, such as two half-bearings formed by oppositely-arranged grooves in the pillar and top plates. As such arrangement forms no part ot' the present invention, I have omitted an illustration of it in order that the parts which do embody-,my invention and which will now be described mayappear more clearly in the drawings.
A lever g, pivoted at g/ to the front plate, has its inner end g2 projecting into the path of movement ofthe end or head b2 of the arbor and has its outer end g3 formed with a preferably curved surface, as indicated, said lever having also a shoulder g4. A spring 7L is secured by means of a screw h to the front plate ct and is preferably steadied in position by means such as a dowel-pin. The outer or free end of the spring bears against the shouldergl of the nlever g and normally acts to hold the lever g in the position shown in 'Fig'. l. A sleeve-operatin g lever i is pivoted to the plate d at t" and has its longer end entering the peripheral groove e3 of the sleeve. This lever t' is located in a recessf, formed in the plate a, said recess being of such a depth that the lever will be substantially flush with the said plate a, so that all the parts will occupy a very small space. Secured to said lever 1l, as by a screw 7a and asuitable dowel-pin, is a spring 7c, having its'intermediate portion curved or bent, so that no contact will be made with the end of the lever g excepting at the iixed and free ends of said spring k. The fixed end of the spring lc is formed to present an abutment 7a2 for the end of the lever g, and adjacent to said abutment is a cam-surface k3. When the crown is pushed inward so that the end or head b2 swings the lever g to the position shown in Fig. 2, the outer end of said lever g engages the free end of the spring k, andl through said spring yieldingly moves the sleeve-operating lever t', so as to slide the sleeve into position where its outer teeth e will engage the teeth cl' of the pinion d. When the parts are in this position and the arbor is being rotated backward, the spring 7c permits the lever il to yield with the sliding movements of the sleeve-clutch. Upon pulling the arbor outward the spring h causes the lever g to swing, so that its end g2 follows the movement of the arbor, and the outer end g3 of said lever g is carried from the position shown in Fig.
IOC
2'to the position shown in Fig. l, its outer end act-ing against the cam-surface 7a3, and consequently oscillating the lever t', and inally coming to a stop behind the abutment k2, entirely leaving the free end of the spring 7c. The swinging of the lever t' throws the sleeve to a position so as to disengage it from the teeth ofthe pinion CZ of the winding-frame, and carries the teeth e2 of said sleeve into engagement with the teeth of one of the pinions of the settingtrain in the usual manner. Since the outer end of the lever g is opposite the abutment 7a2, Which, as above stated, is fixed on the lever 1'., the said lever t' is held positively in the position shown in Fig. l, so that if any member of the setting-train tends to Catch or stiel( the resistance afforded thereby cannot cause a slipping of the clutch-teeth e2, for the reason that the sleeve e is held firmly by said lever 'L'.
Having now described my invention and set forth one embodiment thereof, I Wish it to be understood that I do not limit myself to the specific construction illustrated and described, as the same may be modied toi more or lessextent Without departing from the spirit of my invention.
I claim- A stem Winding and setting mechanism for Watcl1es,oomprisingalongitudinally-movable stem-arbor, a sleeve-clutch thereon adapted to alternately engage the Winding and setting trains, the lever g having one end in the path of movement of the stem-arbor, and having a shoulder g4 between its end and the pivot, the lever t' engaging the sleeve-clutch to reciprocate it and provided with an abutment and an adjoining cam-surface to be engaged by the adjacent end of the lever g, said lever ft' being provided With a spring extending from the abutment to the opposite side of the pivot and adapted to be engaged by the end of the lever g alternately With the engagement with said abutment.
In testimony whereof I have allxed my signature in presence of two Witnesses.
ANDERS AUNE.
