Specification of Letters Patent. Patented June 6, 1922.
Application med June 3, 1921. serial No. 474,623.
To allie/"tom it may concern:
i Be it known that I, ..Orro DoLL, a citizen of the United States of America, residing at Greenwich, Fairfield County, Connecticut, United States of America, have invented certain new and useful Improvements in Dial Trains; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specificaton.
My invention relates to dial trains for time pieces, and more especially for such time pieces as are provided with an extra hand carried by one of the hands normally present in the time piece, or carriedv by a sleeve on which a normal hand is mounted. Such time pieces, watches or clocks, are usually provided with an extra hour hand to show differences in standard times, differences in dz light saving time, handicap for races, &c.
.ly invention consists in providing mechanism for setting this additional hand so that such hand can be conveniently set with respect to the hand with which it is associated, without having to goto a watch- -maker or jeweler to have this done.
I have chosen to illustrate my invention in connection with a watch, and the additional hand moves in unison with the *hour hand. The additional hand maybe associated with any other hand if so desired.
Referring to the drawings, in which like parts are similarly designated- Figure l is a cross section of the dial train illustrating means for setting the additional hand from the watch stem.
Fig. 2 is a perspective View showing a modification.
Fig. 3 is a plan view of a watch showing means independent of the stem for setting the additional hand.
Referring to Fig. 1, the watch movement is represented diagrammatically at 5 as having the usual winding spindle 6, and the head 7 held projected by a spring 8. In such a stem-winding watch the head 7 is turned to wind, and is pulled out to set, as is customary. In addition to this I provide a pinion 9 Which, upon pushing in thevhead 14 in the sleeve 15 of the usual hour hand 16. The sleeve 12 carries the auxiliary hand 17. D is the customary dial. f
The minute pinion e, with the reducing wheels f, g, and. h are those customarily used.
Said minute pinion e is here shown as provided with a sleeve 18 on which the minute hand m is shown fastened. This sleeve may be omitted, as is the case in many time pieces.
For' operation, the head 7 is pushed in and turned,thus causing pinion 9 to mesh with and rotate wheel 10, which in turn rotates wheel 11 and sleeve 12 that carries the additional hand 17. y
The sleeve 12 slips on the sleeve 15 of the hour hand 16.
In Fig. 2 I have illustrated lever mechanism for stepping wheel 11a by pressing the stem of the watch without rotating the stem. Or, in lieu of using the watch stem, a separate depressible pin may be used, as in Fig. 3. The head 7 is depressed against the action of spring 8 and rod 6it strikes the end of a bent lever 19 projecting through a hole 20 in the top plate t of the watch movement. This lever is pivoted at 21 and is urged by aspring 22. Pivoted to the end of lever 19 is a pawl 23 having a nose 24: resting against a stationary pin 25 in plate t and urged by a spring 26.
By pushing in the head 7, lever 19 is swung on pivot 21 against the action of spring 22, drawing the pawl 23 to the right. The pawl being urged by spring 26 against the pin 25, slides into engagement with ratchet wheel 11a and steps it, and thus moves the additional hand step-by-step.
In Fig. 3 I have illustrated a modification of the stepping mechanism for the additional hand 17. i
` In the watch case rim there is a depressible pin 28 having a head 29 that rests on a bellcrank lever 30 pivoted at 31 to the upper plate of the movement. This lever is urged by a spring 32 against the head 29 and holds the pin 28 normally projected. On the end of lever 30 is pivoted a toggle pawl 33 urged against a pin 34 by a spring 35.
By depressing the pin 28 pawl 33 is pushed forward to step the ratchet Wheel ll for setting the additional hand 17.
Other modifications may be employed for setting the additional hand independently of the main or usual hands of the time piece Without departing from my invention.
I claim I l. In a dial train, the combination With hour and minute hands and their driving;
wheel on said sleeve and a toggle pawl for stepping said ratchet wheel.
3. In a dial train, the combination with hour and minute hands and their usual. driving` mechanism including a sleeve upon Which the hour hand is secured; of a sleeve in frictional engagement with the Virs't sleeve, an additional hand thereon and a rate-het wheel thereon, a pawl, a pin, a springr to urge 'the paWl against said pin, a bellcrank lever to Which said pawl is pivoted, a spring to urge said level: and a pin for operatii'ig said lover to cause the paWl to step said ratchet wheel and. set the additional hand.
In testimony that I claim the foregoing as my invention, I have signed my name hereto.
OTTO DOLL.
