SPECIFICATION formingpart of Iietters Patent No. 232,737, dated September 28, 1880.
Application filed June 21Y 1880. (No model.)
To all whom it may concern:
Be it known that I, HENRY A. LUGRIN, of the city, county, and State of New York, have invented certain newand useful Improvements in Stop-Watches, of which the following is' a specification.
This invention relates to improvements in stop-watches in which the timing attachment is thrown in or out of gear with the watchmovement by means of two toothed wheels and an intermediate double-beveled pinion; and the invention consists of a timing attachment consisting of a toothed wheel on the arbor of the fourth wheel, of an intermediate doublebeveled 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 quarter-second hand at its opposite end. The arbor of the split quarter-second hand passes through the hollow arbor of the quartersecond hand, the latter being provided with a shifting mechanism, lifting-lever, and spring to throw its toothed wheel in or out of gear with the pinion, while the arbor of the split quarter-second hand has a stop-disk at the top of the movement. The arbor of the minutehand is provided with a stop-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-hand 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 face view of my improved stopwatch on an enlarged scale. Fig. 2 is a vertical central section of the same. tail side views of different forms of the motiontransmittin gwheels and double-beveled pinion and Figs. 5 and 6 are, respectively, a bottom and a top view of the movement, showing the mechanism for stopping the split minute-hand 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 second-hand, and which is made either with tion by throwing the toothed wheel A Figs. 3 and 4 are destraight or beveled teeth or in the nature of a crown-wheel, as shown, respectively, in Figs. 4, 2, and 3. The toothed wheel meshes, by a small intermediate double-beveled pinion, B, with a second gear-wheel, A, which is keyed to a hollow arbor, G, 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 suitably-graduated auxiliary dial that encircles the face-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 of the quarter-second hand.
The quarter-second hand D is set into mointo gear with the intermediate double-beveled pinion, B, which is accomplished by the withdrawing of the beveled lever a from a liftingspring, I), and the action of a spring, (I, interposed between the toothed wheel and frame of the movement.
By throwing the lever a under the spring b the spring I) lifts the hollow arbor O and gear-wheel A, so that the connection with the double-beveled pinion is interrupted and the motion 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 movement and sent after the quarter-second hand by the usual spring and cam. Both hands D and D are then returned jointly to the starting-point by the usual return-lever g and heart-shaped cam g on the arbor of the quarter-second hand employed in stop-watches.
The arbor of the minute-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 quarter-second hand, as follows: When the quarter-second hand is set in motion the return-lever g is carried away from the heartshaped cam, and, pushing against a lever-arm,
g throws a lever-arm, g, at the opposite end of its shaft against the disk h of the split min to stop it. The minute-hand while the split minute-hand is When the return-lever g, at the end lite-hand, so as then goes on, stopped.
of the observation, falls back to its first position on its cam the lever-arm releases the disk h, which, by means of its spring, sends the splitminute-hand into line with the minutehand and returns simultaneously therewith the quarter-second and 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 second-hand and of an intermediate double-beveled transmitting-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 set forth. 2. In a stop-watch, the combination of the hollow arbor of the quarter-second hand, passmg through the hollow arbor of the minutehand, and being connected thereto at the top of the movement, with transmitting-gearing and mechanism for throwing the hollow arbor in or out of gear therewith, as set forth.
3. In a stop-watch, the combination of the hollow arbor of the minute-hand, carrying a disk and split minute-hand, with a stop-lever and shifting mechanism working jointly with the shifting mechanism of the quarter-second hand, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 16th day of June, 1880.
HENRY A. LUGRIN.
