STOP-WATCH.
SPECIFICATION forming part of Reissued Letters Patent No. 10,770, dated September 28, 1886.
Original Neils-3,737, dated Scplcinlmr 2S, 1880. Application for reissue L led May 2?, i886. Serial NoflOfiAfiS.
To all whom it may concern:
Be it known that I, A. LUGRIN, of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Stop atches; and I do hereby declare that the following is afull, clear, and exact description of the invention, that 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 the let ters of reference marked thereon, which form a part of this specification.
This invention relates to improvements in stop-watches in which the tiniing attachment is thrown in or out of gear with the watchmovement by means of the two toothed wheels and an intermediate double-beveled pin-ion; and the invention consists of a liming attachment consisting of a toothed wheel on the arbor of the fourth wheel, of an intermediate double-beveled transmitting-pinion, and of a second toothed wheel'which is applied to a hollow tubular arbor that passes through the hollow tubular arbor of the minute-hand and carries the quartcrsecond hand at its opposite end. The arbor of the split quarter-second hand passes through the hollow arbor of the quarter-secom'l hand, the latter being provided with a shifting mechanism, liiting'lcver, and spring to throw its toothed. wheel in or. out of gear with the pinion, while the arbor of the split qi'iarter-sccond hand has a stop-disk at thetop ol' the movement. The arbor of the min ute-hand is provided with astop-disk and with a sleeve-shaped arbor which carries a split minute-hand. A spring-arm bears on the disk and stops the split minute-halal when it is desired to use the split quarter-second and minute hands. The split minute-hand is carried up to the minute-hand when the stop-disk is released by the usual shifting mechanism.
In the accompanying drawings,Figure 1 represents a faceview of myimproved stop-watch on an enlarged scale. Fig. 2 is a vertical central section of the same. Figs. 3 and; are detail side views of different forms of the motiontransmitting wheels and double-bcveled pinion; and Figs. 5 and 6 are respectively a bottom and a top view of the movement, showing the mechanism for stopping the split minutehand and shifting it to the minute-hand.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, A represents a toothed wheel which is keyed to the arbor of the seconds-hand, and which is made either of a crown-wheel, as shown, respectively, in Figs. 4, 2, and 3. The toothed wheel meshes, by a small intermediate (1 ouble-beveled pinion, B, with a second gear-wheel, A, which is keyed to a hollow arbor, C, that passes through the hollow arbor of the minute-hand and'to the other side of the movement, and carries at its opposite end the quarter-second hand D, which moves along a suitablygraduated auxiliary dial that encircles the race-dial of the watch. The split quarter-second hand D is arranged on the same side of the movement, its arbor D being passed through the hollow arbor ol' the quarter second hand.
The quarter-second hand D is set in motion by throwing the toothed wheel A into gear with the intermediate double-beveled pinion B, which is accomplished by the withdrawing of the beveled lever a from the lifting-spring Z), and the action of a spring, (I, interposed be tween the toothed wheel and frame of the movement.
By throwing the lover a under the spring I) the spring I; lifts the hollow arbor G and gearwheel A, so that the connection with the double-beveled pinion is interrupted, and the 1110- tion of the quarter-second hand stopped.
The split quarter-second hand is stopped in the customary manner in stop-watches by a friction-disk, e, and lever f at the top of the 'movcment, and sent after the quarter-second hand by the usual spring and cam. Both hands D and D are then returned j ointly to the starting-point by the usual return-lever, y, and heartshaped cam g on the arbor of the quarter-second hand employed in stop-watches.
The arbor of the minnte-hand E carries a disk, h, to which the split minute-hand E is connected by a sleeve.
The split minute-hand works in connection with the quartersecond hand, as follows: When the quarter-second hand is set in motion, the
with straight or beveled teeth or in the natureretnrn-lever g is carried away from the heartshaped cam, and, pushing against a lever-arm, g, throws a 1ever-arn1, 9*, at the opposite end of its shaft against a disk, h, of the split minute-hand, so as to stop it. The minute-hand then goes on while the split minute-hand is stopped. When the return-lever g at the end of the observation falls back to its first position on its cam, the lever-arm g releases the disk h, which, by means of its spring, sends the split minute-hand into line with the minnte-hand, and returns simultaneously therewith the quar; ter-seeondand split quarter-second hands to the starting-point.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent 1. In a stop watch, the combination of a toothed wheel on the arbor of the seconds-hand, and of an intermediate double-beveled trans mitting-pinion, with a toothed wheel on the arbor of the quarter-second hand, and with a lever and spring devices for throwing the toothed wheel of the quarter second hand in or out of gear with the transmitting-pinion, as
9 set forth.
2. Ina stopwatch, the combination of the hollow arbor of the minute-hand, the hollow arbor of the quarter second hand passing through the hollow arbor of the minute-hand, transmitting gearing located at the top of the movement, mechanism for throwing the arbor of the quarter-second hand in or out of mesh with said gearing, the arbor of the splitqnar- HENRY A.
