JOHN M. LOCKWOOD, OF SAN FRANCISCO, CALIFORNIA.
ELECTRIC-LIGHTING SYSTEM.
SPECIFICATION forming part of Letters Patent No. 472,623, dated April 12, 1892.
Application filed June 22, 1891. Serial No. 397,145. (No model.)
To all whom it may concern:
Be it known that I, JOHN M. LOOKWOOD, of the city and county of San Francisco, and State of California, have invented certain new and useful Improvements in Locating and Indicating Disturbances in Electric Circuits, my invention being specially designed for 10- cating and indicating such disturbances in electric-light circuits.
To this end my invention consists in the means and apparatus illustrated in the accompanying drawings, in which Figure 1 represents a front view of my improved device or apparatus with the front of the casing removed, showingthe operative parts thereof; and Fig. 2 represents a perspective view of a portion of the device or apparatus.
Referring to the drawings, the letter A indicates a board or support for the parts of my device.
A indicates a solenoid of the usual construction, the terminals I J of which may be placed inthe main line of an ordinary electric circuit.
The letter B indicates a soft-iron bar, which is located within the interior of the solenoid and is adapted to move freely therein vertically. The said bar at its lower end is secured to the bent end a of a bar I). The said bar Z) is set between guides or ways b secured to one side of the frame A which supports the gearing of the device. The bar 5 at one side is provided with a series of teeth a, which intergear with the teeth of a cogwheel C, mounted upon a shaft D, having its j ournal-bearin gs in the frame A before mentioned. The said shaft has mounted thereon a cog-wheel e, which intergears with a pinion c on a shaft having its journal-bearings in the frame A The shaft 0 projects at one end beyond its bearing and has mounted upon its projecting end a disk 6', the periphery of which is provided with a series of teeth corresponding in number to the number of the station in the system.
The letter It indicates a brush secured to a block H of insulating material, the said brush being located so that its free end will be in the path of the travel of the disk 0 in such manner that the teeth of said disk, when the same is rotated, will come successively in contact with the brush, in order to give a stepby-step signal at the main station in case of any disturbance in the circuit. The brush has connected to it a conductor L, and the frame A a conductor K, which may be placed in a circuit leading to the source of generation of current of the main line.
The letter E indicates a cog-wheel mounted on the shaft 0 which intergears with a pinion c mounted upon a shaft 0 which carries a cog-wheel F, intergearing with a pin- 7 ion B mounted upon the shaft B which has its journal-bearings in the frame A To the upper end of the bar I) is secured a plate I), which oversets the wheel G, and by coming into contact with the same arrests the gearing of the device when the proper signal has been given.
Ordinarily the regulators of this class have been provided with gearing operated by a spring. Such devices have to be wound to be put in operative condition- By my improvement it will be perceived that the device is automatically wound or set and arrested at the proper time.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
The device herein described for indicating and locating disturbances in electric circuits, the same consisting in the combination of a solenoid connected in the main circuit, a bar adapted to move therein, a train of gearing adapted to be automatically wound by the movement of the bar, a rotating disk and brush adapted to be connected in circuit with an alarm or indicator at the source of generation, and a plate atthe upper end of the bar, adapted to arrest the movement of the gearing when the signal has been given, substantially as specified.
In testimony whereof I have signed the foregoing in presence of two witnesses.
JOHN M. LOCKVVOOD.
