ELECTRIC CLOCK.

SPECIFICATION forming part of Letters Patent No. 750,492, dated January 26, 1904.

Application filed May 9, 1908. Serial No. 166,477. (No model.)

To (Z7, whom, it may concern:

Be it known that I, FRED SCHMIDT, a sub ject of the Emperor of Germany, residing at Oak Station, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Mechanisms for Electrically Operating Clocks, of which the following is a specification- This invention relates to certain new and useful improvements in mechanisms for electrically operating clocks and is also adapted for use in connection with the operating of watches or wherever it is applicable.

The invention aims to construct a new and novel mechanism adapted for use for electrically operating clocks or watches, said mechanism dispensing with the use of the ordinary springs, weights, or other like devices generally employed for operating clock or watch movements.

The invention aims to construct a mechanism for the purpose herein specified, which shall be extremely simple in its construction, strong, durable, efficient in its operation, and comparatively inexpensive to set up or manufacture.

To this end the invention consists of the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification and illustrating my new and novel mechanism for electrically operating clock or watch movements as applied to a clock-movement.

In the drawings, Figure 1 is an elevation of the operating mechanism as applied to a clock-movement. Fig. 2 is a perspective view of the operating-lever of the movement-operating mechanism. Fig. 3 is an elevation of the circuit'forming arm of the movement-opcrating mechanism. Fig. 4: is an elevation of the movement impulse-wheel of the movement-operating mechanism. Fig. 5 is an elevation of a portion of the movement-operat- Figs. 6 and 7 are elevations Fig. 8

' is a modified form of operating-lever used in connection with the impulse-wheel shown in Fig. '7.

Referring to the drawings by reference characters, 1 denotes a suitable clockmovement, provided with a spring-actuated balancewheel 2, which cooperates with the escapement-lever 3, the latter forming a part of the operating mechanism for the movement 1.

Arranged in suitable relation and forming a part of the operating mechanism for the movement 1 is a magnet at, having acounterbalanced armature 5 cooperating therewith. The reference characters 6 7 denote the leading-in or circuit-forming wires and which communicate with a source of electrical energy. The leading-in wire 6 is suitably connected to the magnet A, and the connection formed by the leading-in wire 7 will be hereinafter referred to. If desired, a suitable switch 8 maybe employed for cutting out the circuit entirely.

The armature 5 is mounted upon a rockshaft 9 and has its outer end provided with a weight 10, and its inner end extends over the top of the magnet 4. The position of the armature is such that when the magnet is energized it will be attracted thereto and rock the shaft 9, as the armature is fixed to the shaft 3). The latter is suitably insulated from its supports. The rock-shaft 9 has mounted thereon the eseapement-lever 3, the latter being insulated from the shaft 9. The free end of the lever is bifurcated and is adapted to be engaged by the balancewheel 2, so as to rock the shaft 9 in an opposite direction to that given the shaft when the armature 5 is attracted by the magnet. The function of this movement will be hereinafter referred to. The shaft 8 also carries an upwardly and outwardly extending supporting-arm 11, which is suitably insulated therefrom and has its free or outer end connected, by means of the spring 12, to the operating-lever 13. The spring 12 is electrically connected to the rock-shaft 9 by means of the wire 14:. The lower end of the lever 13 terminates in a hook 15, the latter being insulated, as at 16, for a function to be hereinafter referred to.

The reference character 17 denotes the impulse-wheel for the movement 1, and this wheel 17 may also be termed the circuit breaker and maker. The wheel 17 is mounted upon and suitably insulated from the shaft 18, which is provided with the pinion 19, meshing with the gear-wheel 20 of the movement 1.

impulse-wheel 17, the pinion 19, meshing with the gear-wheel 20,will impart movement thereto, thereby operating the movement 1. The impulse-wheel 17 is toothed, so that the teeth thereof can be engaged by the hooked end 15 of the operating-lever 13, and when the lever is elevated through the rocking of the shaft 9 when the magnet 4 is energized and the armature 5 attracted thereto the hooked end 15 of the lever 13 will carry the impulse-wheel 17 therewith and rotate the shaft 18. The impulse-wheel 17 has one face thereof provided with a series of insulations in the form of disks suitably spaced apart, as at 21, and these insulations are adapted to break the circuit in a manner as hereinafter referred to. The face of the impulse-wheel, which is provided with the insulations, is engaged by the lower end 22 of the circuit-forming arm 23. The latter is formed of spring metal, so that it will always bear against the insulated face of the impulse-wheel 17. The upper end of the circuit-forming arm 23 is secured to a connecting-arm 2 1, the latter in turn being attached to the leading-in wire 7.

The insulation of the hooked end 15 of the lever 13 is such that when the lever 13 is elevated the non-insulated portion of the hooked end 15 will contact with one of the teeth of the impulse-wheel 17; but when the lever 13 is lowered the insulated portion 16 of the hooked end 15 will ride over the teeth of the impulse-wheel 17. \Vhen the impulse-wheel 17 is rotated, or rather when an impulse is given to the wheel 17, the circuit-forming arm 23 or the lower end 22 of the circuit-forming arm will ride against the insulated face of the impulse-wheel 17, and when the end 22 of the circuit-forming arm bears against the non-insulated portion of the insulated face of the impulse-wheel 17 the circuit will be closed; but as soon as the end 22 engages with the insulations the circuit will be open. The impulse given to the wheel 17 by the operatinglever 13 is such as to carry the insulation in the form of the disk 21 past the hooked end 22 of the circuit-forming arm 23, and just as this movement is accomplished the insulated portion 16 of the hooked end 15 of the operating-lever 13 will be in engagement with the impulse-wheel 17, thereby opening the cir cuit. If this insulated. portion 16 of the lever 13 were not in contact with the impulsewheel 17, then the circuit would be closed, for the reason that the end 22 of the circuit-forming arm would be bearing against an uninsulated portion of the insulating-face of the impulsewheel17. When the circuit is open, the shaft 9 is rocked in a counter direction, owing to the armature 5 being counterbalanced and also owing to the assistance of the balance-wheel 2, which acts upon the esca )ement-le\ 'er 3.

From the foregoing description it is evident that when the circuit is formed the arma- VVhen the shaft 18 is rotated by means of the ture will be attracted, thereby elevating the lever 13, and the latter carries the impulsewheel 17 therewith, consequently operating the movement 1, and that when the circuit is open the lever 13 will be lowered, owing to the action of the counterbalanced armature and escapement-lever 3 and balance-wheel 2, and that when the end 15 of the level-13 rides over the teeth of the impulse-wheel 17 until the uninsulated portion of the hooked end 15 contacts with the teeth the circuit will be again closed and the impulse-wheel 17 again operated in the manner as set forth.

In Fig. 6 a modified form of impulse-wheel is shown, which is indicated by the reference character 25. In this construction of impulsewheel contacts 26 are provided instead of in sulations. This is obtained by insulating entirely one face of the wheel 25 and providing said wheel 25 with the raised contacts 27, which extend through the insulations.

In Fig. 7 another modified form of impulsewheel is shown, which is indicated by the ref erence character 28, and this modified construction consists of providing the upper portion of each of the teeth with an insulation, as at 29'.

In Fig. 8 is illustrated the form of operating-lever employed in connection with the modified form of impluse-wheel shown in Fig. 7. This modified form of lever is not insulated-that is to say, the hooked end 31 thereof is not insulatedas it is not necessary, owing to the fact that the teeth of the impulse-wheel 28 are suitably insulated in the manner just referred to.

The circuit passes through the armatureshaft 9, wire 14, spring 12, lever 13, impulsewheel 17, connecting-arm 20, and wire 7, as well as wire 6, to the magnet 1.

hen my improved mechanism is used in connection with a watch, a sn'iall battery is mounted therein to supply electrical energy. The various parts forming the mechanism for operating a watch-movement are arranged within the watchcase. This can be accomplished by the removal of the various parts of the watch-movement which are not necessary, owing to the fact that the necessary parts of the movement are operated by the mechanism hereinbefore set forth in connection with the operation of the clock-movement.

It will be evident that the operating mechanism hereinbefore described can be applied to any sized clock or watch nlovenwnt without changing or enlarging the size of the said movement and that it is also particularly adapted for use for operating old clock or watch movements, for the reason that no additions are necessary simply the removal of certain parts of the movement and the application thereto of the operating mechanism hereinbcfore described, which can be readily placed in position or attached to the movement.

It is thought the many advantages of my improved mechanism for electrically operating clock or watch movements can be readily understood from the foregoing description, taken in connection with the accompanying drawings, and it will furthermore be evident that changes, variations, and modifications can be resorted to without departing from the spirit of the invention or sacrificing any of its advantages, and I therefore do not wish to restrict myself to the details of construction hereinbefore described, and as shown in the accompanying drawings, but reserve the right to make such changes, variations, insulations,

and modifications as come properly within the scope of the protection prayed.
