FREDERICK W. COLE, OF NEWTON, MASSACHUSETTS, ASSIGNGR TO THE GAME'WELL FIRE ALARM TELEGRAPH COMPANY, G1 NEW' YORK, N. 2., A CORPORATION OF NEW YORK.

SUPERVISORY SIGNALING DEVECE FGR CLOCKS.

To all whom it may concern:

Be it known that I, FREDERICK V. COLE, of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Supervisory Signaling Devices for Clocks, of which the following is a specification.

This invention relates to supervisory signaling-devices for clocks or other timingmechanisms, and has for its object to provide a signaling-device adapted to be operated to cause a notification signal to be given or transmitted to a central-station, especially in case the clock or other timingniechanism becomes disabled. It is of especial value in connection with automatic fire-alarm and watchmans supervisory signal-systems in which the continual operation of timing-devices is depended upon for sending signals or causing signals to be sent, and also for recording the signals. The invention is also applicable to other systems and apparatus embodying a timing-mechanism, when it is desired that notification shall be given when said mechanism becomes disabled or runs too fast or too slow.

The invention consists in embodying a timed-supervisorymechanism in connection with the timing-mechanism, and a signal ingdevice for indicating the stopping; of the timing-mechanism, or of either the timing-mechanism or the timed-supervisorymechanism, and also for indicating when the timing-mechanism and timed-supervisory-mechanism are running out of synchronism., so that in case of any trouble whereby the timing-mechanism is disabled or its control affected, notification will be. given.

A signaling-device is preferably employed and its circuit is adapted to be operated or controlled by the joint action of said timing-mechanism and timed-supervisory-mechanism, so that it may be oper ated by either, in case one ceases to operate, or in case they run out of synchronism. The signaling-device employed will prefer ably be a code-signal transmitter, and in such case several may be connected in a single circuit connected with a central-station, and when more than one transmitter is employed different identification signals will be sent. The code-signal transmitter is aplapted to be released or otherwise operatec.

Figure 1 is a. front view of a suflicient portion of a watchmans clock to illustrate this invention, together with means embodyingthis invention for operating a sig- 112ill11'*(lQVlCG in case said clock stops or runs too fast or too slow. Figs. 2 and 3 are details to be referred to. Fig. 4 is a side view of the parts shown in Fig. 1. Figs. 5, 6 and 7 are details to be referred to. Fig. 8 is a diagram of the circuit to be referred to. Fig. 9 is an enlarged detail of one of the contact-members, together with a diagram of a circuit having a modified form of signalingdevice, and, Figs. 10 to 15 inclusive are details showing modified forms of circuit-opcrating devices for the circuit of the signaling-device.

(4 represents the removable dial of any usual or suitable watchmans clock, or equivalent timing-mechanism, and a" one of several electro-magnetically operated markers for marking or puncturing .the dial or otherwise indicating a signal thereon in re sponse to the operation of a circuit, such as n, Fig. 8, by a watchman.

(4 represents a toothed wheel which may be secured to the minute-shaftof the timing-mechanism, which is engaged by an idle pinion (4 which in turn engages a toothed wheel a, secured to a shaft 0", so that said toothed wheel a revolves in synchronism with the toothed wheel a making a complete revolution once an hour. A hand a is secured to the shaft a which moves over a small dial c lVith the exception of moving the minute hand a to one side of the center of the clock-train and mounting it on an independent shaft instead of connecting it with the shaft bearing the toothed wheel (4 the timing-mechanism thus shown is constructed as the ordinary watchmans clock, but is here shown particularly for illustration. Hence my invention is not limited to any particular construction of timing-mechanism, or to the employment of a dial and cooperating devices whereby it is adapted to serve as a. watchmans clock.

Z) represents one of the train-wheels of a timed-supervisory-mechanism of any usual or suitable construction. and l) the minuteshaftthereof. A pendulum clock is here shown as the timed-supervisory-mechanisin, merely for the purpose of illustration. Said timed-supervisory-mechanism is timed to run in synchronism with the aforesaid timing-mechanism, and, as here shown, is designed to be employed as a controller for said timing1nechanism, and also to be controlled by said timing-mechanism. In carrying out. this part of my invention, as shown in Figs. 1 to 9, the minute-shaft a of the timing-mechanism and the minuteshaft 6 of the timedsupervisory-mechanism, each having secured to them a disk, and said disks, represented at c and 6!, respectively, are arranged eccentrically on their shafts and in the same relative positions. The eccentric disk 0 is embraced by the forked end of a lever c, pivoted at a and having an upwardly extended arm 0 provided with a bifurcated laterally extended finger 0*, which embraces an ear 0', arranged at the lower end of and projecting at right angles from an upright shaft. 0", supported by suitable end bearings, so that as the minute-shaft c revolves, said lever moves back and forth slowly on its pivot, making one complete vibration during each complete revolution of the minute-shaft, and the shaft a correspondingly reciprocates rotarily, moving through a short are. The eccentric disk (Z is embraced by the forked end of a lever cl, pivoted at (F, and having a downwardly extended arm (Z composed of insulating material, which bears a pair of contact-pens (Z (Z the ends of which are extended below the end of the arm and are spaced apart. As the shaft 6 revolves the lever (Z moves back and forth slowly on its pivot, making one complete vibration during each complete revolution of the disk and the arm (Z bearing the contact-pens correspondingly vibrates. The upper end of the reciprocating shaft 0 bears a short arm 0 see Figs. 5, G and 7, which projects therefrom at right angles, and bears a contactpen 0 which projects into the space between the two contact-pens (Z (Z and normally occupies a middle position therebetween.

Assuming the timing-mechanism and timed-supervisory-mechanism to be set at unison, and the contact-pen c disposed midway between the contact-pens d, (Z it will be seen that as long as they run in synchronism, the levers will be moved by the eccen tric disks and the relative positions of the contact-pens d, (Z and 0 will remain unchanged, see Fig. 5, and the circuit m of the signaling-device will not be operated, but in case the timing-mechanism stops the contact-pen 0 will cease to move and will be soon overtaken by one of the contact-pens (Z or (Z and engagement effected, see Fig. 6, whereby the circuit in see Figs. 8 and 9, including said cont, ct-pens will be operated, and in case the timed-supervisory-mechanism stops the contact-pens (P, (Z will cease to move and one of them will be soon overtaken by the contact-pen 0 and said circuit m operated. Or, in case either the timingmechanism or timedsupervisory-1nechanism runs out of synchronism with the other, as for instance, too slow or too fast, the contact-pen will be moved relatively to each other and into engagement to operate said circuit in. Thus the signaling-device is prevented from operation by the timing-mechanism and timed-supervisory-mechanism, acting conjointly, when running in synchronism, but is permitted or caused to operate whenever either stops or when they run out of synchronism, the means to operate said signaling-device being automatic.

The circuit 127., includes a battery m, and may include a releasing-magnet m, see Fig. 8, for a code-signal-transmitting-device m whereby a code-signal, for instance an identification-number, will be sent over a circuit m, which will operate the recorder m, or other signaling-device. In lieu of employing a recorder as a signaling-device, the circuit m may directly include a bell. m, or other form of alarm apparatus, see Fig. 9. Thus, in case either the timing-mechanism or timed-supervisory-mechanism stops, or runs out of synchronism with the other, the sigiulling-device is operated to give notification of the trouble. '7

In lieu of the means above described for operating the signal-circuit, the form shown in Fig. 10 may be employed, wherein the aforesaid eccentric disks 0 and (Z are re spectively arranged to directly operate pivoted levers e and 6, bearing electric contacts for the signal-circuit. Or the form shown in Fig. 11 may be employed wherein the eccentric disks 0 and (Z respectively operate spring-acting pivoted levers c and c, bearing electric contacts for the signal-circuit. Or the form shown in F 152 may be employed wherein one of the contact-pens, as f, for the signal-circuit, is connected with "the minute-shaft of the timed-supervisorymechanism, and its cooperating contact pen f is connected to a sleeve f mounted on said shaft, and is operated by the minute-shaft of the timing-mechanism by belt or other suitable means, said contactpens being insulated from each other and arranged to engage each other in case either the timingmechanism or timed-supervisory-mechanism stops or runs out of synchronism with the other. Oathe form shown in Figs. 13 and 14, may be employed wherein one of the con tact-pens, as g, for the signal-circuit is fixed and the other, as g, is movable, and said movable contact-pen engages a cam-disk 9 arranged on a sleeve on a shaft g", and said disl-c bears a bevel pinion g, which is interposed between a pair of bevel-gears y, one connected with the minute-shaft of the timing-mochanism and the other with the minute-shaft of the timed-supervisorymechanism, so that in case either tl1eti1ning mechanism or timed-supervisory-mechanism stops or runs out of synchronism with the other, said bevel -pinion g will travel around the bevel-gears, and the cam disk to which it is connected will be rotated to lift the contact-pen g and operate the signalcircuit. Or the form shown in Fig. 15 may be employed, wherein two circularly arranged sets of contact-plates 7L and h, are provided, one for the timing-mechanism and the other for the timed-supervisory-mechanism, over which move contact-pens or wipers 7L2, h which are connected respectively with the minute-shafts of said timingmechanism and timed-supervisory-mechanism, and said contact-pens are connected in the signal-circuit, as shown, so that said circuit may be operated by either wiper.

From the many modifications shown, it will be apparent that I do not desire to limit my invention to the particular means here shown for operating the signal-circuit, as long as said means is arranged and operated by either the timing-mechanism or timedsupervisory-mechanism, in case the other stops or runs out of synchronism.
