ELECTRIC CLOCK -SYNCHRON|ZER.

. SPECIFICATION forming part of Letters Application filed May 16,1901.

To all whom, it 71mg colwrrlt:

Be it known that I, CHARLES F. MEARS, a i citizen of the United States, residing at Silver l City, in the county of Mills and State of Iowa, have invented a new and useful Electric Clock-Regulator, of which the following is a specification.

This invention is an attachment to be used purpose of regulating the same.

The object of the invention is to provide an attachment which can be arranged at the base of any pendulum clock and connected to a telegraphic line, which in turn connects to a central regulating-station, so that by closing the circuit at the central station any and all clocks in electrical connection with the main line will be regulated or started synchronously.

With these objects in view the invention consists in the peculiar construction or" the various parts and in their novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a diagrammatic view illustrating my invention. Fig. 2 is a side elevation of the central-station mechanism arranged in connection with the sounder. Fig.

echanism detached from the sounder.

In carrying out my invention I employ an ordinary telegraphic sounder A, which is connected with the line B, having batteries 0 an ranged therein and also a push-button or circuit-closer D. An electromagnet E is also arranged upon the sounder-frame and in electrical connection therewith. This electromagnet E is employed for the purpose of setting and releasing the regulating mechanism, which is electrically connected to one or more attachments arranged in connection with one or more pendulum clocks.

F indicates an operating-arm to the upper voted a lever G. The end G of said lever G is adapted for" contact with the sounder-arm, while the end G? is made hooked and is intended to engage thebevel endof the arm H, pivoted at its lower end, as shown at H, and carrying an armature I,

is pressed in adva which is adapted to be attracted by the elec- Patent No. 702,666, dated June 17, 1902. Serial No. 60,581. (No model.)

tromagnet E. A lever K is pivoted to the upright arm F about midway its height, the forward end of said lever being bent back upon itself, as shown at K, to provide a book which engages a lug H carried by the arm H, thereby holding the said arm in its proper upright position, and a lever L also rests upon the lever K,'thereby holding the hooked end in contact with the lug II". The lever L is attached to a bracket L, which is pivoted to the upright arm F. One end of said lever bears upon the end G of the lever G.

M indicates the line extending from the central station to thesubstation containing the clock to be regulated, said line being connected to the electromagnet N, which operates the armature-lever O, which in turn releases an arm P, arranged upon the wheel Q, said wheel having alaterally-projecting restpin R, upon which bears the long arm or the lever S, the short arm S of which contacts or projects into the path of the pendulumrod T.

U represents a bell, and W spring mechanism for sounding the'same, said mechanism being operated by contact therewith of the long arm of the lever S as it falls after being released from the pin R.

In operating my invention the clock to be regulated is stopped a few seconds prior to the time of regulation and the pendulum swung to one side or out of plumb and held in that position by engaging with the short arm S of the lever S, the long arm of said lever being supported by the pin R. The levenH is swung up into position in front of the magnet E and held there by swinging the lever K into its horizontal position and cansing the hook K to engage with the lug H This will necessitate the raising of the lever L until one end of it will engage with the end of the lever G and hold it down out of contact with the sounder at one end and hold the other end of the lever high enough to permit of'the passage of the end of the lever H. At the same time that'this arrangement of parts takes place the hands of the clock should be moved forward to the hourat which the clock is to be started. When the push-button D uce of the time for regulation, the magnet E is energized, drawing the armature I thereto, andthe lug H is thereby moved into a position which releases the lever K, and the weight of the lever L will throw the said lever K downwardly, and at the same time the lever G is released by the lover L, and the end G will drop into engagement with the upper end of the arm- H. At the hour of eleven or twelve or any other hour which may be selected as the time for regulation the circuit is closed by the operator at the central regulating-station, as Vashington, D. (3., Which will operate all theinstrumerits upon the line, and the sounder of each instrument operating upon the end G of the lever G raises thelend (33, so that when the circuit is broken the arm H will drop and its contact-point H will contact with the platinum point M, which forms one of the terminals of the li'ne M. The circuit being thus closed,' the ma 'net N is energized, attracting the armature which immediately releases the arm P, causi-n the Wheel Q to rotate sufifeiently to move t e pin R from beneath the arm S, and the said arm dropping releases the pendulum and at the same time operates the striking mechanism and sounds the bell. The clock will thus be started and the bell sounded at the exact moment of sounding the signal from the main or central station, and it will of course be understood that any number of regulating mechanisms maybe operated from one main or central station.

It will also be understood that the means for setting and releasing used in connection with the sounder may be changed or varied somewhat Without departing from the broad principles of my invention.

Having thus fully described inyinvcntion, What I claim as new, and-desire to secure by Letters Patent, is

1. In adeviceofthe kind described,thc combination with the sounder, an electromagnet arranged in connection therewith, an armature arranged in connection with the said magnet, an arm carrying the said armature, a lever mechanism for releasing the said arm, the elbow-lever for checking the motion of a pendulum, the electromagnetic means for releasing the said lever, the line connecting the said electromagnetic device, and the sounder, the swinging arm carrying a contact-point adapted to close the circuit, substantially as set forth.

2. The combination with a sounder, of an upright arm carrying a lever at its upper end and a lever intermediate its end, and a third lever adapted to hold the other levers in position, a pivoted arm carrying an armature, and a contact-point, the line-wires and air;

cuit-closer, the electromagnet and its armature, the rotating wheel carrying the arm and pin, and the elbow-lever adapted to rest upon the pin, and the bell. and striking mechanism, all arranged and adapted to operate, substantially as described.
