SECONDARY ELECTRIC-CLOCK MOVEMENT.
SPECIFICATION forming part of Letters Patent No. 456,325, dated July 21, 1891.
I Application filed November 8, 1890. Serial No. 370,763. (No model.)
To ctZZ whmn it may concern.-
Be it known that I, BENEDIKT I-l'ABEErniiE, a citizen of the Swiss Republic, residing; at Breitenbach, Canton of Soleure, Switzerland, have invented certain new and useful Improvements in Electrical Secondary Clock- Works, of which the following is a specification.
This invention relates to secondary electric clocks with a striking mechanism.
Figurel 0f the accompanying drawings is a front elevation of the mechanism partly broken away. Fig. 2 is a rear elevation thereof. Fig. 3 is a'vertical transverse section on the line 3 3 in Fig. 2. Fig. 4 is a vertical transverse section on the line i at in Fig. 2.
The clock shown is adapted to be actuated by an electric impulse sent over a circuit at intervals of one minute or other suitable intervals.
In addition to the usual electromagnetic mechanism for imparting motion to the hands, the improved clock has a striking mechanism which continually rewiuds itself through the action of the electro magueticallydriven clock mechanism. The electro-magnet B is fastened by its pole ends a a to the base-plate A. The coil of the electro-magnet is in an electric circuit which is closed every minute by an electric standard clock. On the lower pole end a two angular supports b" l) are screwed, and in the latter turn the pivots c c of an angular armature-lever (l, which is connected at thetop with an arm d. The movement of this arm d, and therefore of the armature-lever C, is limited on the one hand by a shoulder e of the upper pole end a, and on the other hand by the face of a regulating-nut E on the screw D. The upper end of the arm (Z is connected by a connecting-rod F with one end of a leverG of the first class, which can turn on a pivot fon the plate A, and which lever carries at its other arm a pawl H, operating on a ratchet-Wheel I. A spring g presses the nose lb of the pawl 11 continually against the teeth of the ratchetwheel I, and by means of a stop-pin "i the motion of the pawl II is limited to the extent of one tooth of the ratchet-wheel I at a time. A stop-pawl E, opposite the pawl ll, prevents the backward motion of the ratchet-wheel I. The latter is designed to be actuated from the standard clock once each minute, and has therefore sixty teeth. It is fixed on the minute-arbor J, which has bearings in the bridge j of the base-plate. The minute arbor .l carries a wheel 0, whose rotation is transmitted through the wheel Z, pinion n, and wheel on to the hou r-arbor K, as in any ordinary hand-operating mechanism. The pinion n meshes also with the wheel 7;, which is fastened on the arbor L of the spring-barrel of the striking mechanism and transmits the motion of thehandoperating mechanism to the last-mentioned arbor L. The arbor L, Fig. 3,has bearings at opposite ends in the bridges p q, and the spring-barrel M turns loosely on this arbor. One end of the spiral spring N is fastened to the arborL, while the other end is fastened to a projection of the spring-barrel M. The rotation of the spring-barrel M is transmitted by means of the wheel 0 and the intermediate wheels and pinions r r, s s, and t t t to the fly or regulator PjFi gs. 1 and 2, so that the rotation of the spring-barrel is regulated by the latter. The arbors of the wheels and pinions 2" r, s s, and t if t have bearings at one end in the base-plate A and at the other end in the bridges Q and Q. Two or more stoppins it connect the spring-barrel M with the striking-wheel R, which is provided with seventy-eight teeth, and carries on its rear surface tw'elve stop-pins o to @2 The intervals or successive distances of these stop-pins correspond with the successive numerals 1 to 12, the first two o and o being separated the width of one of the teeth of the wheel, the second two '0 and o the width of two teeth, &c. A stop-hook S on an arm pivoted on a stud y engages any of the stop-pins t" to r", and its arm is connected by means of a sleeve with a lever-arm T, having a tooth The other lever-arm V is connected with a spring U in such a manner that the hook S and the lever-arms T V can turn around the stud y on the base-plate. The lever carries a spring 00, the end of which is bent down close to the hook S, serving to reduce the shock of this hook when it strikes the pins '2) to @2 ()u the stud Z, which is fastened to the plate ISO A, is pivoted a movable block Z, having a nose ,2. This block Z carries the hammer \V, which can strike against a gong X. The nose 2 is kept in mesh with the teeth of the wheel R by means of its own weight or of a spring.
On the ratchet-wheel I is provided a disconnectingarm \V, having a projection it at its rear end, and at the end of each rotation of the wheel I-that is, at the beginning of each hourthe arm IV strikes the end tooth z of the lever-arm T, by means of which the hook S is shoved aside, so that the striking- Wheel R is freed, whereupon this wheel turns, under the tension of spring N, until the next stop-pin is engaged by the hook S, which arrests it.
The operation of my electric secondary clock is as follows: At the end of every minute the armature O is attracted by the electro-magnet B, and its motion transmitted by means of the connecting-rod F to the lever G, the pawl II, the ratchet-wheel I, and then to the hand-operating mechanism, so that the minute-hand moves the distance representing one minute. This motion of the hand-operatin g mechanism is transmitted to the wheel 0 on the arbor of the spring-barrel M, and thereby the spring N is wound up partly after every minute. On the expiration of every hour the disconnecting-arm \V of the wheel I strikes the lever-arm T, and thereby the hook S is displaced to one side, so that it is moved out of the way of the stop-pins t" to 11 so that the strik ng-wheel R is free and turns by means of the tension of spring N. By this turning motion the teeth of the striking-wheel R operate on the nose .2" of the movable block Z, so that the hammer strikes the hour on the gong X. As on the one hand the spring-barrel makes a complete turn in twelve hours, and on the other hand, in consequence of the operation of the handbperating mechanism on the spring-barrel arbor L, the latter also makes a complete revolution in twelve hours, it is obvious that the tension of the spring N is always the same at a certain hour of the day. Instead of the bridges Q Q, fastened on the rear part of the plate A, a second plate may be provided.
I claim as my invention the following defined novel features, substantially as hereinbefore specified, namely:
1. In an electric clock, the combination, with a hand-propelling mechanism and electro-magnetic means for driving it, of a striking mechanism, a motor-spring therefor, and mechanical means in connection with said hand -propelling mechanism for rewinding said spring.
2.

3. In a secondary electric clock, the combination of a hand-propelling mechanism comprising a minute-arbor, a ratchet and pawl, an electro-magnet for operating the 'pawl, a striking mechanism, the motor-spring thereof, the arbor of said spring geared to the handpropelling mechanism, whereby said spring is rewound by said latter mechanism, and a projection carried by the minute-arbor adapted to release the striking mechanism.
at. In a secondary electric clock, the combination of an actuating-magnet, a pawl and ratchet, a minute-arbor carrying a projection, a striking mechanism comprising a strikingwheel having stop-pins, a stop-lever having a hook engaging said pins, and a tooth adapted when engaged by said projection to release said hook, at motor-spring for said striking mechanism connected thereto at one end and to a motor at the other, and gearing connecting said arbor with the minutearbor, whereby said spring is periodically rewound.
5. In a secondary electric clock, the combination of an electro-magnet B, its pivoted armature G, opposite stationary stops e and E for limiting the vibration of said armature, lever G of the first class connected at one end to the armature-lever, a pawl H, connected to its other end, and a ratchet-wheel I, adapted to be advanced by said pawl during the attractile stroke of the armature.
6. In a secondary electric clock, the combination, with a hand-propelling mechanism comprising a minute-arbor carrying a projection to, of a striking mechanism comprising a striking-wheel having stop-pin s, a stop-lever having a hook S for engaging said pins, a spring 50, carried by said lever, bent down close to the hook, so that it shall reduce the shock when the hook strikes the stop-pins, a spring U for imparting a tension to said lever, and a tooth .2, carried by said lever and engaged by said projection r11, for displacing the lever to disengage said hook.
