UNrrED STATES PATENT OFFICE.
EDUARD WVENSOH, OF VIENNA, AUSTRIA-HUNGARY, ASSIGNOR OF ONE HALF TO JOHN JAMES HANHART, OF SAME PLACE.
ESCAPEMENT FOR CLOCKS AND WATCH E S.
SPECIFICATION forming part of Letters Patent No. 256,418, dated April 11, 1882.
Application tiled December 12, 1881.
To all whom, it may concern Be it known that I, EDUARD WENsGH, engineer, subject of the Emperor of Germany, residing at Vienna, Empire of Austria-Hungary, have invented certain new and useful Improvements in Escapements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as 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 letters or figures of reference marked thereon, which form a part of this specification.
The object of my invention is to provide a new and improved escapementfor watches and other machines, in which the power is not transmitted directly from the escapementwheel to the balance or pendulum, whereby the movement of the watch, clock, or other machine will be more regular and uniform than that of watches or clocks provided with the ordinary eseapements.
This invention is an improvement on the escapement for which Letters Patent No. 247,721 have been issued to me on the 27th day of September, 1881, and it consists in a balancewheel provided with an eccentric pin, and with an eccentric on its arbor, the latter eccentric being between the prongs ofa fork on the upper end ofapivotedanchorprovided with twoteeth, and an arm for checkin g'the escapement-whcel at intervals, and locking, releasing, and pushing back a pivoted lever provided with a projection, and operated by a spring or weight, which lever acts on the eccentric pin of the balance-wheel, which is thus not operated by the motor of the clock or watch and independently of the power of this motor.
In the drawings, Figures 1, 2, and 3 show plan views of my improved eseapement, showing the same in its various positions. Figs. 4 and 5 show modifications of the lever for actuatin g the balance-wheel.
The balance-wheel b is pivoted to the top of the plate P of the works and to the bridge k,
and is provided with ahair-spring, s, in the ordinary manner.' A small eccentric, e, is mounted on the shaft or arbor of the balance-wheel, and is surrounded 0r embraced by the prongs of a (No model.)
fork at the end of a rod or anchor, g, pivoted to the plate P at w, and provided equidistant above and below the pivot or with a tooth, p and p, respectively, these teeth being slightly curved and inclined toward each other. The upper tooth, p, is provided with a curved arm, a, above the escnpement-wheel r, pivoted to the plate 1. A rod or lever, f, is pivoted at its lower end to the plate P, and is acted upon by a spiral spring, S, or equivalent device, which turns or presses it in the direction toward the escapement-wheel. This lever f is provided with a tooth, stud, or shoulder, a, directly above the periphery of the escapementwheel. An eccentric pin or stud, 1', projects from the central plate of the outer or upper surface of the balance-wheel b.
The operation is as follows: As shown in Fig. 1, the eccentric has reached its maximum of movement toward the left, and the escapement-wheel is engaged with the teeth of the anchor. As the wheel 9' is rotated in the direction of the arrow a by the works the tooth 3 of this wheel a" will rest against the tooth p of the anchor g. The tooth l of the wheel r strikes against the projection or stud a of the lever f, which lever is moved toward the right, whereby the spring S is increased in tension. The stud i is diametrically opposite the end of the lever f, and is at its greatest possible distance from the end of this lever.
The balance-wheel b swings back in the direction of its arrow, and the parts will be in the position shown in Fig. 2, and the eccentric will have obtained its maximum movement toward the right. The eccentric c has moved the fork of the anchor toward the right, and the tooth p of the anchor has been moved toward the escapement-wheel 1', whereby the tooth 3 of this wheel will be disengaged and will rotate in the direction of the arrow to until the tooth p of the rod g arrests the tooth 2 of the escapement-wheel. The tooth 1 of the escapement-wheel has passed under the projection a of the leverf, whereby this lever is liberated, but is immediately checked by the arm a, which has moved downwardzso as-to strike against the projection to. The studz' passes the leverfeasily without changing the positions of the other parts; Now thebalancewheel swings backward, as shown in Fig. 3, whereby the eccentric moves the fork of the anchor toward the left again,and removes the end of the arm n from the projection a without disengaging or liberating the tooth 2 of the escapement-wheel r. The lever f is pressed against the stud t by the spring S, and gives an impulse to the balance-wheel I) until the projection a strikes against the tooth 5 of the escapement-wheel. B y further rotation orswin ging of the balance-wheel b in the direction of its arrow, as shown in Fig. 3, the tooth 2 of the escapement-whecl will be disengaged, and the escapemcnt-wheel rotates in the direction of its arrow at until it is checked by the tooth 1) of the anchor or rod g, against which the tooth 4 ofthe escapement-wheel strikes; but in the meantime the tooth 5 of the escapementwheel has moved the leverf toward the right again, and has the same position that the tooth 1 of the escapement-wheel has in Fig. 1, and all the other parts are in a corresponding position, as shown in Fig. 1, and in this manner the escapement operates as long as it is im pelled by the works of the watch or clock.
In place of the spring S, the leverf can be provided with a rectangular arm carrying an adjustable weight, G, as shown in Fig. 4; or the lever f can be replaced by a spring-strip f, provided with a projection to and attached to an angle block, W, (attached to the plate P,) as in Fig. 5, the operation being the same as described above.
The escapement-wheel r can in no manner transmit the power of the motor to the balancewheel I) but the movement of this balancewheel depends entirely upon the power or tension of the spring S, (or its equivalents, such as the weight G or spring strip f,) which power always remains the same independently of the power of the motor. The rotations or oscillations of the balance-wheel will thus never vary, and the movement of the escapement-wheel is checked atintervals, constantly remaining the same, and governed by the balance-wheel b.
This device, when slightly altered, can be used with apendulum as well as with a balancewheel. 7
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the balance-wheel b and the escapement-wheel r, of the pivoted lever f, provided with a projection, a, and means for pressing it toward the escapementwheel, the pin i, the pivoted rod 9, provided with teeth 1) p, and an arm, a, substantially as herein shown and described, and for the purpose set forth.
2. The combination, with the balance-wheel b, having an eccentric pin, 1', and with the escapement-wheel r, of the eccentric 0 on the shaft of the balance-wheel, the pivoted rod g,
provided with a fork and with teeth 1) p, and
an arm, n, and of the pivoted lever f, provided with a projection, a, substantially as herein shown and described, and for the purpose set forth.
In testimony whereofI aflix my signature in presence of two witnesses.
