WATCH.

Application led June 18, 1924. Serial No. 720,841.

To all whom t may concern.'

Be it known that I, SAMUEL KREssnR, a citizen 0f the United States, and a resident of the borough of Manhattan, city of New York, county and State of New York, have invented certain new and useful Improvements in Watches, of which the following is a specification.

This inventionl relates generally to watches and more particularly to bracelet and wrist watches (or pendant watches) and coordinately resides in the provision therewith in watches of this class of second hand indicators and dials for use of physicians, nurses, etc., whenever there are the lrequlrements for Seconds units readings or indications of the operations of thewatch.

It is common practice to build separate and distinct `'seconds unit dials and main face dials, but these do not present a symmetrical appearance and are also objectionable because the main face is subordinate and the seconds unit dial is dominant to vision. The movement for such watches is also not adapted for standard forms of cases. Seconds unitV dials have been placed on circular watches. seconds unit dial being disposed radially from ythe center or concentric, is consequently almost always tangential to the main circular dial, with the result that in viewing the watch face, -the main dial is dominant visually and the seconds unit dial is subordinate largely because the radial markings are prone to be coincident with the. radial movement ofthe hour and minute hand. Thi-s visual subordination is particularly more pronounced in watches of such diminutive sizes a'sare ordinarily used in wrist orJ bracelet watches.

I have found that by elongating the main 'watch dial or face symmetrically, a seconds Aunit dial marked on such a ,face and disposed vfrom the position concentric to the path made by the hands at the center of the watch, will no longer assume -the subordinate visual position but will receive prominence and conspicuousness and serve its utilitarian purpose most readily.

I have further found that the visual prominence of the seconds unit dial is accent'uated if the seconds unit dial is not located upon the main coordinate axes passing through the center of the watch.

I have found further that not only is this optical prominence accentuated if the In such cases, the` seconds unit dial is not located upon the main coordinate axis passing through the center, but that in symmetrical non-circular dials whereinthe numerals are not equidistant from the center and fall outside the reach of the hour and minute hands in reading, obscurity is prevented and accuracy is assured if the seconds unit dial is not located so as to interfere with vision between the hands and the' markings most divergent which are located radially from the center.

rIherefore, the object generally of my invention is to augment the conspicuousness or visual prominence of the seconds unit dial and indicator upon watches in relation to the main hour dial.

further object of my invention is the combined augmenting of conspicuousness and visual prominence of the seconds unit dial and indicator and ready facility yin reading of hour and'minute reading` in noncircular watches.

A still further object of my invention is the provision of a combined symmetrical non-circular watch-face dial and certain improved mechanical details in watch movements.

For the attainment of these objects and such further objects as may appear herein after, I will now describe my invention, making reference to the following drawing by way of illustration in which- Fig. l represents a front face view of a non-circular octagonal watch;

Fig. 2 represents a rear view of a movement as shown in Fig. l;

Fig. 3 represents a front face view of an oval non-circular movement; i

Fig. l represents a rear face vie-w of a movement as in Fig. 3;

Fig. f-fis a section taken on line 5-5 of Fig. 2. Y,

In the drawings, 10 represents a noncircular or oblong watch face within casing axes. Upon such form of watch face I locate the seconds unit dial 14 preferably with the usual divisions of 60 seconds. This dial is preferably located so that it is disposed or oset from at least one main axis,

vthough if such seconds unit dial is symmetrical in shape, the dial may be placed upon any of the main axes if the hourand minute dial is of unequal diameters.

To produce a disposition of the seconds unit dial from both the major and minor axes, I preferably associate with the dial of the above-mentioned character, a lwatch movement whose train of gears do not have the line of center of the stem wind 13, the pivots of the main hands O and the seconds unit gear coincident with either one of the coordinate axes. The line passing through stem wind shaft 13 and the center of the main hands O may be coincident with either one of the axes but the third point of the center of the seconds unit gear must then be o' the axes.

In the drawing 15 is the seconds unit gear which is shown disposed from the main axes X-X, Y-Y.

The seconds unit gear 15 is driven by the minute hand gear 16 through the Vintermediate gear 17 and controlled by the escapement 18 and the balance wheel 19. The shaft of the seconds unit gear 15 is extended at 20 through the front face jewel or bearing 21 and slightly beyond the main bearing plate 22 and is coincident with the opening 23, the center of the seconds uni't dial 14.-. The seconds hand or indicator 24 is mounted on the sleeve 25 frictionally en gaging the shaft 20 for turning therewith.

The movement plates' 22 are preferably made of the same geometric shape as the casing 11 and made to snugly fit said casing. However, movements having lother shaped main bearing plates than the noncircular main face dial may be used, provided the seconds unit gear shaped center and the main hands shaft center will not coincide with the main coordinate axes of the dial of the non-circular shape chosen when these parts are xedly engaged to each other.

Though I have shown in Figures 1 and 2 a 4symmetrical octagonal Watch and movement, any symmetrically formed geometric figure having unequal diameters taken on the major and minor axes at right angles to each other will serve equally Well.

In Figures 3 and 4 I have illustrated an oval watch movement having unequal diameters in which the arts corresponding in function to those in igures-1 and 2 are marked with like numerals primed.

The main face dial or hour and minute i dial has inscribed upon the same the hour and minute markings disposed lradially from the center and following in form the contour of the perimeter of the particular' geometric figure chosen.

Though I prefer to have the seconds unit dial and indicator disposed or offset from both the coordinate major and minor axes, I may'locate the seconds unit dial upon one of the main axes provided it is located upon the sections of the main face dial whose radial hour and minute markings are not substantially the most divergent.

In the drawings, I have practically this condition and for purposes of illustration have shown the dial between the IX and XII position with the XII and VI falling on the major axis. The most divergent radial markings of hour and minute dial will fall on the longer diameters passing through the center O. Thus disposed from the most divergent markings, the accurate reading of the time when the hands point in positions intermediate between the major and minor axes is assured and made facile. The visual lining-up of the hour or minute hands with the minute or hour markings furthest from the center is not obscured by positioning the seconds unit dial near the short diameter of the non-circular symmetrical dial.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is 1. A watch dial ofy a non-circular symmetrical geometric form whose diameters along coordinate axes are unequal, and a seconds unit dial offset from a position on .the coordinate axes.

2. A watch dial of oblong form having an aperture therethrough arranged to receive a seconds unit indicator therethrough, said aperture offset from the major and minor coordinate axes thereof.

3. A watch dial of oblong form having the major axis lon er than the minor axis and a seconds unit dial offset from the major axis.

4. A watch dial of oblong form having the major axis longer than the minor axis, an aperture through said dial arranged to receive a seconds indicator therethrough, said aperture o'set from the major axis.

5. A Watch dial of a non-circular symmetrical geometric form whose diameters along coordinate axes are unequal, hour and minute markings thereon, arranged along substantially the same contour as the dial and arranged to receive a seconds unit indicator therethrough at a position offset from the axes.

6. A watch movement, a stem wind gear, and wind shaft therefor, a line therethrough forming with the center of the hour and minute hand drive thereof one of the coordinate main axes, the seconds unit gear shaft thereof extended through the front face bearing thereof, arranged to engage dial as set forth in claim l.

an indicator, said seconds unit gear shaft offset from one of the main coordinate axes Said movement adapted to be used With a 7. An oblong Watch and dial whose markings are arranged near the edge of the dial in substantially similar contour including a movement Whose train of gears are arranged in substantially the same contour as said Watch, a seconds unit gear having its shaft extended through the front face bearing thereof, said shaft arranged to drive a seconds unit indicator through said dial.

8. In combination a Watch, movement and case therefor, a Watch dial of oblong form having the major axis longer than the minor axis, a seconds unit dial offset from one of the axes mentioned, an aperture through the second mentioned dial, said movement having the seconds unit gear shaft thereof extended through the front face bearing thereof arranged to engage an indicator and a seconds unit indicator mounted on said shaft through said first mentioned dial and aperture.

9. in combination, a Watch, movement and case therefor, a Watch dial of oblong form having the major axis longer than the minor axis, a seconds unit dial offset from the axes, an aperture through the second mentioned dial, said movement having the seconds unit gear shaft thereof extended through the front face bearing thereof arranged to engage an indicator and a seconds unit indicator mounted on said shaft through said first mentioned dial and aperture,

In Witness lwhereof, I have signed this specification, this 10th day of June, A. D. 1924.
