CHARLES H. MEYLAN, OF NEV YORK, N. Y., ASSIGNOR TO MATHEY BROTHERS, MATHEZ d? OO., OE SAME PLACE.
WATCH-BARREL.
SPECIFICATION forming part of Letters Patent No. 410,32*?, dated September 3, 1889.
Application filed June 8, 1889. Serial No. 313,545. (No model.)
To all whom it may concern:
Be it known that I, CHARLES H. MEYLAN, of the city and State of New York, but temporarily residing at Brassus, Switzerland, have invented an Improvement in Spring- Barrels for lVatches, of which the following is a specification.
In watches that contain two trains of gearing for independent or split seconds in stopwatches and for striking the time in repeating-watches two spring-barrels have been made use of, one spring-barrel giving motion to the main train or time gearing and the other to the independent seconds-hand or to the striking devices. These barrels, however, have been upon separate arbors and have occupied considerable space in the watch, and the devices t-hat communicated motion from one spring-barrel to the other, whereby only one movement was necessary in winding, have been complicated.
My present improvement is for simplifying the construction and lessening the cost of manufacture and for lcssening the space occupied by the spring-barrels. I place the two springs and the two spring-barrels around one arbor, and in consequence of the second spring having comparatively little work to perform it can be made quite narrow, and hence the space occupied by the two springbarrels on one arbor is` but little increased, and I take the movement for one train of gearing from awheel around the edge of each spring-barrel.
In the drawings, Figure l is an elevation illustrating the connections to the winding mechanism, and showing the relative positions of the two spring-barrels. Fig. 2 is a plan view of the mainspring -barrel, and winding-gearing. Fig. 3 is a section, in larger size, of the spring-barrels; and Fig. at is a plan view of the secondary-spring barrel and its spring.
The niainspring-barrel A is provided with gear-teethB around its periphery, from which the necessary movement is given to the train of gearing extending to the escapement and balance, and the secondary-spring barrel O hasgear-teeth D around its periphery, which give motion to the train of gearing extending to the independent seconds or striking mechanism. These trains of gearing' and devices employed in connection with them may be of any desired character and do not form a necessary part of the present invention. The arbor E passes through the two barrels A and O, and its ends are suitably supported, usually in the plates or bridges. of the watch, and upon the hub 3 one end of the mainspring 4 is hooked, and the other end of such mainspring #i is hooked inside of the springbarrel A. This spring and the hooks may be of any desired character.
Upon the arbor F is a hub 5, preferably screwed thereon, and to this hub 5 one end of the secondary spring 6 is attached, and the other end of this secondary spring Gis turned outwardly at right angles, or nearly so, and catches into one of the notches 8 within t-he barrel C.
It will now be understood that when the arbor F is rotated to wind up the mainspring the secondary' spring G will also be wound up; but after this secondary spring has been wound up to the proper point, if the winding of the mainspring is continued, the outer end of the secondary spring G will slip out of one of the notches S, and continue to slip from one notch to the other until the winding ceases, and in this operation the secondary spring will not be injured, and it will be wound up to a sufhcient extent for performing whatever duty is required of it in moving the parts that receive motion from the secondary` spring barrel.
It is tobe understood that the arbor F, as it is rotated, is to be held by a suitable ratchet and pawl; hence the inner ends of both springs are held rigidly when the winding operation ceases, and the mainspring uncoils itself in the ordinary movement of the watch, and the secondary spring may or may not be brought into operation before the watch is wound up again; and it is to be understood that this secondary spring is to be of sufficient length and strength for any duty that may be required of it between one winding and the next of the mainspring-barrel. I prefer to make use of a square 10 upon one end of the arbor F, upon which is a gearwheel Il, having a square hole to fit the square lO, and a surrounding hub passing into ahole IOO in the bridge or plate K, and this wheel H has teeth that are adapted to receive a pawl or clickL upon the plate or bridge K, and this Wheel H is geared 'into the Wheel M, that receives motion from the gear N of the stem- Winding` mechanism. These parts may be of any desired or ordinary construction in stein- Winding Watches, and it will be apparent that the arbor F might be wound by an ordinary key, if so desired.
In many instances the spring-barrels of Watches are provided with a stop mechanism,
2. The combination, with the arbor F, of Y the mainspring' and spring-barrel A, for giving motion to I[he ktime mechanism in a Watch, the hub 5, surrounding the Windingarbor F, the secondary barrel C, and gear D, also surrounding the arbor F, and the spring 6, connected at one end to the hub 5 and having a projecting end that catches into notches in the interior of the secondarybarrel C,sub stantially as set forth.
3. The combination,With the Winding-arbor F, mainspring and spring-barrel A, around such arbol', of the secondary spring and spring-barrel C, also Iaround the arbor F, a Wheel H, having a central opening setting over the square end of the arbor, and a circular hub entering a hole in the Watch plate or bridge, and a pawl for holding such wheel H, substantially as set forth.
Signed by me this d3d day of May, 1889.
