ADJUSTABLE DIAL FOR WATCHES.
. SPECIFICATION formingpart of Letters Patent No. 227,415, dated May 11, 1880.
Application filed February 9, 1880.
To all whom it may concern:
Be it known that we, EDGAR O. OOVELL and WILLIAM F. CHASE, of Laconia, in the county of Belknap and State of New Hampshire, have invented an Improvement in Watches; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification Figure 1 being a view of so much of the movement of an American stem-windin g watch as will show our invention in connection therewith, the view being toward the inner side of the bottom plate; Fig. 2, a view of the outer side of the bottom plate, showing the few changes in its construction requisite for applying our invention, the part of the movement above the said plate being omitted in the view; Fig. 3, a view of the inner side of the dial, showingits construction as adapted to our invention.
Like letters designate corresponding parts in all of the figures.
The purpose of our invention is to so construct a watch and its movement that without any change thereof it is adapted to be used either in an open-face case, with the pendant over the figure 12, or in a hunting-case, with the pendant in line with the figure 3, the dial being movable from one position to the other, and all the parts of the watch being ready for its arrangement in either position.
In the accompanying drawings, A repre sents the bottom plate of the watch; B, the dial, and O the pendant. The large centerwheel D, which receives its motion directly from the spring or drum wheel, gears into the pinion a of an intermediate wheel, E, which gears into the pinion b of the fourth or secondhand wheel G, which gears into the pinion c on the staff of the escape-wheel. The above is the ordinary arrangementfor a huntin g-case watch, and we do not change it; but we add another wheel, H, with a pinion, (i, into which the center-wheel D gears, and another second-hand pivot or staff, I, with a pinion, f, thereon, into which the wheel H gears, the said wheel and pinions being of proper proportional size to give the same rate of motion tolhesecond-hand on this staff as on the ordinary staff. No gear-wheel is used on this additional second-hand staff, since it does not require to be connected directly with the staff of the escapement-wheel, which receives its motion through the regular train. Little or no additional poweris required with this additional second-hand gear, and the regular train is uninterrupted. The position of the second-hand staff I is at the same distance from the center pivot of the watch as the regular second-hand staff and one-fourth of a circle from it in circumferential direction. The additional gear is represented as being between the plates of the watch; but it may be between the bottom plate and the dial.
In connection with the additional secondhand gear, we employ a shifting dial, which may be placed either in position for an openface case or a hunting-case without any disturbance of the parts or movementof the watch.
For this purpose it is arranged to be mounted in positions one-fourth of a circle apart, so that the figure 12 thereon may come in line with the pendant, or the figure 3 in line therewith. As the simplest and best method of effecting this purpose we make four holes, 1 g g, in the bottom plate at one-fourth of a circle apart in convenient positions, and arrange two feet, h h, on the under side of the dial, diametrically opposite to each other, as shown in Fig. 3, so that these two feet will have two holes in the plate to fit into in either position of the dial.
\Ve also make recessesi i in the back of the dial, to receive, one or the other, the secondhand pivot not in use, in the two positions of the dial. The second-hand, of course, is to be secured on the pivot which comes in the hole of the dial in the respective positions thereof. lVe do not confine ourselves to the precise number of feet and feet-holes for shifting the dial represented in the drawings, but may adopt any number or arrangement that will provide holes for the feet in both positions of the dial, or any equivalent of the device therefor herein described. In lieu of this part of our invention, two dials might be used with the other feature of our invention.
\Vhat we claim as our invention, and desire to secure by Letters Patent, is-
1. In combination with a watch having a second-hand on a separate staff in a position outside of the center, a watch-dial constructed and adapted to be applied to the Watch in either of the positions employed for an openface or a hunting-case. substantially as and for the purpose herein specified.
2. The additional secondhand gear and staff, in combination with the regular secondhand movement, and adapted to receive the second-hand interchangeably with the said regular movement, substantially as and for 10 the purpose herein specified.
The foregoing specification signed by us this 30th day of December, 1879.
