SPECIFICATION forming part of Letters Patent No. 390,333, dated October 2, 1888.

Application filed July 27, 1387. Serial No. 245,415. (Xo model.)

To aZZ whom it may concern:

Be it known that I, ABRAHAM M. Baen- RACH, of the city, county, and State of New York, have invented certain new and useful Improvementsiu Attachments to Time-Pieces, of which the following is a specification.

This invention relates to an improved attachment to Watches and clocks, by which is indicated on the dial Whether the movement has run down and requires rewinding, so that the watch or clock is wound up at the proper time, and by which, furthermore, the overstraining of the mainspring in Winding up the same is obviated.

rlhe invention consists of an attachment to the movements of watches and clocks, which attachment is operated by the driving meehauism, and which comprises a toothed segment that is loosely applied to the arbor of the hour-Wheel, said segment being provided with a smaller segment that meshes with a pinion on the arbor ofa pointer that is moved along an auxiliary dial on the face ofthe main dial, said auxiliary dial and pointer indicating at any time the number of hours which the movement has been ruiming. rlFhe toothed segment and pointer are set to their initial or starting position, when Winding up the Watch, by the action of the spring-barrel and suitable intermediate mechanism, and moved by the hour-Wheel and suitable intermediate gearing. To permit the setting ofthe hands by the handsetting devices without moving at' the same time the toothed segment and pointer, the segment is moved out of gear with the motiontransmitting mechanism by the handsetting lever, as will be fully described in detail here inafter, and iinally pointed out in the claims.

In the accompanying drawings, Figure l represents a front elevation of a Watch with my improved attachment for indicating the time which the movement has been running. Fig. 2 is a front view of a Watch-movement with my improved attachment, the dial being removed and the watch shown in the act of going. Fig. 3 is a detail vertical transverse section on line x m, Fig. 2; and Figs. 4 and 5 are top views of the movement with myimproved attachment, showing the same, respectively, in the act of winding it up and in the act of setting the hands.

Similar letters of reference indicate corresponding part-s.

In the drawings, A represents a Watch or clock movement of any approved construction. To the arbor d of the hour-Wheel A] of the same is loosely applied a toothed main segment, B, which is provided nearer to said arbor With a smaller toothed segment, Z), concentric to the former. The toothed segment?) meshes with a pinion, b, on the arbor bz of a pointer or indicator, b, the arbor passing through the dial D, Which is provided with an auxiliary dial, D', of semicircnlar or circular shape at that portion diametrically opposite to the seconds-dial, said auxiliary dial being preferably depressed, so that the pointer bf' can move over the same Withoutinterfering with the hour and minute hands of the movement.

Itis preferable to make the auxiliary dial Dof semicircular shape, as shown in full lines in Fig. l, though it may also be made in eircular shape, as indicated by dotted lines in Fig. l.

rilhe depressed auxiliary dial D" consists of an honrgradnation that runs up to thirty, forty-tivo, or more honrs, according to the time for which the Watch is to rnn. At one end of the dial is arranged the capital letter S, indicating stop,7 and at the other end the capital letter XV, indicating wind, which indicatc, when the pointer arrives at the same, that the time-piece is Wound up sufficiently or that it needs rewinding.

The main segment B is set in motion by a gear-Wheel connection With thehour-wheel A', so as to move with the movement, which gearA Wheel Connection consists of an intermediate pinion, d', a gear-Wheel, d, and a pinion, di, on the arbor oi the gear-Wheel (7F, the pinion dX meshing with the main segment B, as shown clearly in Fig.2. The arbor ofthe gear-wheel d and pinion d3 is supported in bearings of afulcrumed lever, E, which is composed of two parts that are connected by an intermediate spring portion, E', the latter serving to keep the pinion da in mesh with the teeth of the segment B, except when the same is Withdrawn from the same while winding up the movement or setting the hands. As the main segment B is moved by the gears d d2 cl3, connected with the hour-wheel of the movement, it is obvious that the pointer moves over the auxiliary dial D and indicates clearly the condition of the mainspring-that is to say, how many hours the same has been running and how many hours it has yet to run. Vhen the pointer arrives at the opposite end of the auxiliary dial D', the movement is nearly run down and requires rcwinding. The main segment B has then arrived in the position shown in Fig. 4, and has to be returned to its initial or starting position (shown in Fig. 2) by the winding motion of the spring-barrel F and a suitable motion-transmitting mechanism. This mechanism is` interposed between the mainspring-barrel and the segment B, and consists of a gear-wheel transmission, c' e2 e el, supported 011 a pivoted lever, c, and of a pawland-lever connection, ff, between the barrel ofthe mainspring and the fulcrumcd lever E. The gear-wheel transmission consists of a gearwheel, e', that meshes with the ratchet-wheel e on the spring-barrel F, the arbor of the gearwheel e carrying a central pinion, e2. This arbor is supported on the pivoted and springactuated lever e3, which is arranged in a depression of the main plate of the movement. To the outer end of the lever ci* is attached a shorter arm or bridge, c", that carries an arbor, e5, to which are applied a gear-wheel, e, that meshes with the pinion e?, and a pinion, el, that meshes with the main segment B when the mainspring is to be wound up andthesegment returned to its initial position. The bridge e4 is provided with a guard, es, that eX- tendsover the main segment B, and serves as a guide for the same duringits motion in either direction.

During the winding-up motion of the barrel F the main segment movesin the direction f, that engages the teeth of the ratchet-wheel c of the spring-barrel F. Theopposite end of the fulcrumed pawl j is pivoted to a connecting-army, which is guided by a slot, f2, in its opposite end on a headed screw, f3, at one end of the fulcrumed lever E. This end of the lever E is also connected by a pivot-link, f4, with the lever e3, so that by the oscillations of the spring-pawlfin following the motion of the spring-barrel the connecting-arm j" oscillates the end of the lever E, and nieves thereby the pinion el in mesh with the segment B and the pinion d out of mesh with the same, as shown in Fig. 4. At the intervals of time during which the spring-barrel in Winding is at rest the pinion d3 is in mesh with the main segment B and the pinion c7 out of mesh with the same, as shown in Fig. 2.

For the purpose of permitting the setting of the hands without interfering with the attachment that indicates the condition of the mainspring, the pinion d" has to be temporarily moved out of mesh with the main segment B, which is accomplished by an arm, El, that eX- tends from the lever E toward the yoke G of the usual stem-winding and hand-setting mechanism of the movement. The yoke G is provided with a lug, g, that engages the outer end of tlA arm E2 when the hand-setting lever G is pulled out, as shown in Fig. 5. By pulling out the hand-setting lever G the hand-setting attachment is thrown in mesh with the gearwheels of the hands, and simultaneously the lug g ofthe yoke G pressed against the outer end of the arm 2, so that by the spring action of the middle portion, E', the pinion cl3 is removed from the teeth ofthe main segment B, as shown clearly in Fig. 5. In this position the toothed segment B is entirely at rest, and is not moved in either direction while the setting of the hands takes place. As soon as the hand setting lever is returned to its normal position, the arm E2 is released and the pinion Z3 returned to its normal position of mesh with the segment Bby the action of the spring portion E of the lever E.

The attachment described is located below the dial and in full view when the same is removed, so that it can be conveniently repaired in case it should be out of order. The indicating attachment is reset while winding the movement, and is moved by the mainspring simultaneously with the hands of the movement, so as to indicate at any time the exact state of the mai nspring and the exact time when it is necessary to rewind the same. It also acts as an indicator, by which the straining of the mainspriug in winding up the same is obviated, and thereby the iuyuri ng or breaking of the mainspring prevented.

I am aware that it is not broadly new to use in connection with watchesa winding-indicator by which the condition of the mainspring is indicated, said indicator being set in Inotion by the movement from the hour-wheel and returned into its position by a suitable connection with the ratchet-wheel of the spring-barrel, and I therefore do not claim this feature, broadly, but confine myself to the construction of my winding-indicator.

Having thus described my invention,I claim as new and desire to secure by Letters Patent-A l.
