Description

WATCH SETTING LEVER.
APPLICATION FILED JAN. 7. 1918.

UNITE STATES PATENT ()FFICE.
WILLIAM W. JORDAN, OF DELI-II, LOUISIANA.
WATCF-SETTING LEVER.
Application filed January '2, 1918.
To aZZ whom it may concern Be it known that I, l/VILLIAM W. JORDAN, a citizen of the United States, residing at Delhi, in the parish of Richland and State of Louisiana, have invented certain new and useful Improvements in Watchetting Levers, of which the following is a specification.
This invention relates to watches and has for its object to provide an improved setting lever.
Another object of the invention is to provide a lever for stem setting watches which may be operated without removing the watch bezel.
Another object of the invention is to provide a setting lever for watches so formed that when closed in no opening remains in the frame whereby moisture or dust may enter into the works.
Vith the above and other objects in view 1 have invented the device illustrated in the accompanying drawings in which Figure 1 is a plan view of a watch with certain parts removed to show my invention.
Like reference characters indicate like parts throughout the following specification and in the drawings in which 1 is a watch case and 2 the movement, the face and certain other parts being removed to show the winding and setting mechanism. Mounted upon the plate 3 is a slide or lever 4 having a right angular head 5 operating in a slot 6 projecting through the bezel ring 7. The slide 4 is provided at its inner end with an elongated slot 8 through which the screws 9 and 10 project, whereby said slide is held to its place on plate 3. The heads of said screws may frictionally hold the slide against accidental movement if necessary. Said slide 4 is provided on its edge 11 with a rack 12 which is geared with. the segmental gear 13 formed on the arm 14: of the bell-crank lever 15 pivoted upon the screw 16. Rotatably mounted upon the end of arm 17 of said bell-crank lever is a gear wheel 18 so positioned that it is at all times in mesh with the stem operated gear 19, also rotatably mounted on the screw 16. The gear 18 is normally in engagement with the gear 20 which winds the watch spring (not shown).
Specification of Letters Patent.
Serial No. 210,724.
When the slide 4 is pulled out by means of its head 5, the rack 12 operates rack 18, causing arm 14 of bell-crank lever 15 to be thrown outwardly and its arm 17 to be thrown inwardly, throwing gear wheel 18 into mesh with the transmission gear 21 which is in mesh with the gear 22 of the cannon pinion 23, then the operation of the stem head 2% will set the watch, the rotary movement being transmitted to the cannon pinion instead of to the spring operating gear. By again pushing slide 4L in, the transmission is again changed to the spring operating gear 20.
While the above described setting mechanism is especially adapted for use in connection with my air and moisture proof watch case covered by Patent 1,208,707, yet it can be used to very great advantage with all stem wind and set watches as the straight movement of the setting slide or lever makes a much stronger and more preferable device for all makes of cases, asthe open slot in which the arcuate lever operates is done away with and the opening through which the slide operates is kept entirely closed by my form of setting device.
Having now described my invention, that which I claim to be new and desire to procure by Letters Patent is A watch setting device including a bell crank lever having one arm thereof provided at its swinging end with a segmental rack, a pivot pin upon which the bell crank lever is mounted, a shifting gear carried by the other arm of the bell crank lever, a stem operated gear mounted upon the pivot pin and meshing with the shifting gear, a rectilinearly movable slide formed with a rack meshing with the said segmental rack and cooperating therewith to swing the bell crank lever, a spring winding gear arranged to engage the shifting gear at one position of the bell crank lever, and a setting gear arranged to engage the shifting lever at the other position of the bell crank lever.
In testimony whereof I affix my signature in the presence of two witnesses.
WILLIAM W. JORDAN. Witnesses:
