UNITED STATES PATENT OFEIcE.

o. W. SMITH, or EVANS, NEW YORK.

Specification forming part of Letters Patent No. 21,781, dated Octobcr12, 185B.

ing-wires, in which circuits are included devices for lighting street-lamps by electricity,

in such a manner that a portion of the streetv lalnpsof a citvmaybe lighted at a time, thus obviating the necessity of employing a battery of inconvenient and expensive size; secondly, in the combination of conducting-wires with such circuit changer or changers in such a manner that the latter may be operated by means of electricity at a part of the city remote from the operator; thirdly, in arranging the parts of a gas-lighter in such a manner that they will be more compact and less liable to .get displaced than heretofore, as will be de-- scribed.

To enable others skilled in the art to make and use my invention, 1 will proceed to describe its construction and operation.

Figure l is a plan view of the apparatus for lighting street-lamps.

At B is seen'the circuit-changer oi the central station, which is operated by hand. The electric current starting from the battery A proceeds along the conducting-wire to the central pivotofthe circuit-changer; thence through the radial armC to the metallicsegnients D D E E, &c.; thence through the conductingwires which radiate to diflerent secondary or district stations. It will be observed that two of these wires proceed to each district station. One of'these wires, as D, is used to turn around the district circuit-changer, so as to make a connection between the wire D and the different segments of the changer, which communicate also through radial wires with the different circuits of wires in which are included the lamps, one of which circuits is represented on a reduced scale at R. The lamps in this cirthus moves around the radial arm 0 until, by

a succession of strokes, it is brought in contact with the segment communicating with an other circuit; In this manner the different districts and the different sections of each district can be lighted in rapid succession by a battery which would prove wholly inadequate to light them all at once. Sosoou as thelam ps are all lighted, the conducting-wires may be put in connection with the electrograph l P, and thus be used for transmitting signals until the. lamps are tn be rwtinguislmd, vho11 the same operation is to be repeated.

I have alsomade some improvements in the construction of the gas-lighters which are operated as described above.

I place the temporary magnet A, Fig. e, immediately above the supply-cock 13 instead of beneath, as has been done heretofore in all cases, I believe, when a LJ-magnet has been use and support it there by means of the brass plate 0, slips of which are cut and bent so as to form a fulcrum for the lever D and a guide to the pawl E. The devices are thus rendered extremely simple and compact, and it becomes impossible for them to get displaced.

WhatI claim as my invention, and desire to secure by Letters Patent, isi 1. The combination and arrangement of a circuit-changer with different circuits of conducting-wires, in which are included a number of street-lamps, in such a mannerthat the lamps in one circuit only may be lighted simultaneously by means of the battery-current 2. The combination of conducting-wires with devices for operating, by electricity, such a ciredit-changer at a station remote from the operator.

The arrangement of the magnet A, the brass plate 0, the lever D, and the pawl E, substantial] y as and for the purposes described.

CHARLES W. SMITH.
