CHARLES V. VVCERD, CF VVALTHAM, MASSACHUSETTS, ASSIGNOR TO AMERI- CAN WATCH COMPANY, OF SAME PLACE.
IMPROVEMENT IN STEM-WINDING WATCHES.
Specification forming part of Letters Patent No. 161,725-, dated April 6, 1875; application iiled February 19, 1874.
To all whom lt may concern:
Be it known that 1', GnnnLEs V. Women, of XValtham, in the county of Middlesex and State of Massachusetts, have invented certain improvements in Stein-Winding Watches, of which the following is a specification My invention relates to the combination of finger-catch and cam, with spring-lever for yengaging and disengaging the handsetting mechanism to and from the stem or windingarbor, with the Watchease, in such a manner that the linger-catch is entirely covered by the case-cover when the case is closed.
rEhe object of my invention is to bring the Enger-catch out oi' sight, and to cover the saine by the watch-case, and thus improve the appearance of the Watch over Watches ot'this kind, in which the finger-catch is on the outside ot' the case, and interferes with the smooth surface and `finished appearance of the Watch 5 jfurther, to reduce the cost of Watch-cases, and to enable the watch-maker to use the watclrcases as they come from the case-maker, Without requiring extra drilling and iitting in order to make the connection of Enger-catch with cam through the case.
Another object ot my invention is to simplify the combination ot' ringer-catch and cam with spring-lever, to reduce the number ot pieces, and also to protect the inside oi" Watches ei'tectualiy from dust and dirt.
Figure 1 represents an enlarged drawing of the Watch and handsetting mechanism embodying my invention. Fig. 2 is a section of a portion of the same.
teferring to the drawings, a is the upper movementplate; b, the stem-windingmechanism, substantially the same as described in the Letters Patent No. 118,415, granted to me August 22, 1871. c is the spring-lever, which with one end operates into the clutch t, and engages and disengagcs the hand-settin g mechanism, and with the other end is firmly attached to the rim of movement-plate a. rilhe pin d, forming part of spring-1ever c, is acted upon by cam e. The latter, being pivoted to movement-plate c, is provided With two points and intervening cavity, conforming to the curvature of pin d, and an arm with finger-catch f, extending through a slot in Watch-case.
'Vhen the hand-settin g mechanism is disengaged,the arm and Enger-catch f is pushed by the shutting of the case-cover or by the ringer closely against the projecting rim of movementplate, and into a recess of frame holding the glass covering, and when the metallic cover is closed, it will shut over the Enger-catch and arm, and hide it entirely from view. rhe spring-lever f, being released from thepressure ot' cam e against pin d, throws the clutch t', and thus disen gages the h an d-settin g from the stem- Winding mechanism.
When the finger-catch f is pushed outward, the point ot' contact of cam c with pin d., the center of pin, and pivot of cam are brought into position ot' a straight line, thus locking pin d, and causing the spring-lever c to shift clutch i in the opposite direction, and engagin g the hand-settin g mechanism with the Winding-stein.
The Watch-case, forming a separate branch of manufacture, and coming otteu from a distance, requires no extra Work by the case-maker, as the slot and recess for arm and 'linger-catch fcan be easily cut by the Watch-maker.
It Will be seen that when the Watch is closed the cover will it closely around the Watchcase, and that theinside work is perfectly protected from dust and dirt, which cannot be done with Watches Where the ringer-catchv or knob is on the outside of the case.
I do not claim a mechanism in connection with a Watch-case in which the shutting ot the Watch-cover changes automatically the hand-setting to the stem-Winding mechanism, as this has been done before by others; but
What 1 do claim, and desire to secure by Letters Patent, is-
rEhe means for actuating the mechanism whereby the Watch is changed from a stem- Winder to a stein-setter, consisting of the combination, with a Watch, of a cam, c, and thumb-catch f, for actuating the cam, and the flattened surface or landing c, whereby the cam is caused to rest steady, after being raised, until again pressed back into the case, sub stantiaily as and for the purpose described.
