SYSTEM VOF ELECTRIC DISTRIBUTION FOR MOVING TRANSLATING DEVICES.

SPECIFICATION forming part of Letters Patent No. 466,368, dated January 5, 1892. Application ned April 2, v1891. serial No. 387,330. (No moda.)

To all whom, t may concern:

Be it known that I, NELSON W. PERRY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certainnew and useful Improvements in Systems of Electric Distribution for Moving Translating Devices, of which the following is a specification.

My invention relates to the distribution of electricity by a 'current which remains constant in quantity, while the transmitting devices are arranged in series with each other and with the dynamos. l

In my application for Letters Patent of the United States for an improvement in systems of electric distribution filed March 2, 1891, Serial No. 383,350, I have described a system of electric distribution which involves the employment of a 'current-conveyer made in sections, each section being normally connected electrically with the adjacent sections, two lines of working conductors arranged in pairs, each working conductor being normally insulated from the others, switches normally connecting the sections of the main current-conveyer, provisions for automatically opening the switches and diverting the current from the main current-conveyer in such manner that it will pass through the translating de'- vice and return to the normal circuit, and meansfor maintaining the continuity of the current. y

The present invention is designed as animprovement upon the system therein set forth; and it consists in the improved system of distribution hereinafter set forth and in the various circuits and instrumentalities employed relatively to the switches which connect the sections of the main current-conveyer. 5, 6, 7, 8, and 9 are diagrammatic views rept resenting my invention as applied to a single-track road and showing the pathsof the Figs.

current with the motor in several positions relatively to the switches as it travels from left to right. Figs. 10, 11, 12, 13, and 14 are like views showing the paths of the current as the motor travels from right to left. Fig. 15 shows a preferred form of switch. Fig. 16 shows the switch open. Fig. 17 is a diagrammatic view showing the 4trolley and switch connections. Fig. 1S is a like view showing also a local battery.

A A A2 represent sections of the main current-conveyer or normal circuit. Each ot' these sections has at its ends mercury-cups b, separated. by a space from the cups at the ends of the adjacent sections. Into the pairs of adjacent cups normally' take U-shaped double-pole contacts B B B2, &c., which bridge the spaces between the sections and render them electrically continuous.

O C2 C4, &c., represent one line of Working conductors, and C C2 C5, che., another line. Each line of working conductors may be made mechanically continuous by connecting the adjacent ends with insulating material.

D D D2, &c., are solenoid magnets, whose armatures are connected with levers E, with which the forks B are also connected. These magnets are adapted when vitalized to lift the forks from the mercury-cups, thereby opening the switches.

Section A of the main conveyer is electri.;

cally connected with working conductor C by.

means of awire ac, and section A with working conductor G2 by a wire cZc2, dac. IVorking conductor C is connected with section A of the main conveyer through Wire c CZ,-1n`.'algrv1 etz D, and wire da, and working conductorfQSg with section A2 through wire c2cZ,magnet D',

and wire cZa2.

F is a motor provided with trolleys f and f or other current-gathering,devices and adaptl ed to contact with one Of the lines of working conductors. Each working conductor laps the adjacent conductors of the same line, as shown at Z, Z2, Z', and Z2. The laps are so arranged that with the car traveling inthe direction of the main current one trolley-wheel will embrace the lap of the wire connected with the switch before the other trolley-wheel reaches the other lap, and that the trolleywh eel first to embrace a lap will not pass from IOO that lap before the other trolley-Wheel emning cars in different directions upon the` braces its lap. It results that the motor is never without current. With the electrical connections as above described, and a motor upon the sections C C' of the working conductors and in series with the generator or dynamos, the path of the current will be through section A of the -normal circuit, wire ctc, working conductor C, trolley f, motor F, trolley f', working conductor C', wire cd, magnet D, and wire de to section A of lthe normal circuit. When the trlley f reaches a lap Z', the current, after passin g through the motor, momentarily divides, part continuing its former course and part going vict working conductor C3, wirecStZ, magnet D', and wire da? to the normal circuit. The latter current will energize the magnet D and open switch B. When switch B is opened, the current through magnet l) will be cut out of circuit and fork B will drop, closing the switch; but the trolley f will then be in contact with the lap Z, and the current will continue through working conductors C and C3 and magnet D to section A2 of the main current-conveyer. Vhen the trolley f passes from its lap Z, the switch B being closed and the switch B open, the path of the current will be through normal circuit-sections A and A', wire afcz, workf ing conduc'torC2, trolley f, motor F, trolley f', working conductor C, wire cid', magnet D', and wire (Za2 to section A2 ot the normal circuit.

The arrangement thus far described is applicable when cars are to be run in but one direction, as in belt-lines or double-track roads. 'lo adapt the system for use in runsame track additional provisions are requisite. G G G2 are supplemental conductors arranged parallel with but insulated from the working conductors C C3 C5. The supplemental conductors and the laps in the working conductors are so placed relatively to each other that when a ear is traveling in the direction of the main current, as the trolleys approach a lap the trolley traveling upon the line of working conductors connected with the switch will contact with the supplemental conductor before reaching the lapping portion ot` the working conductors, and the companion trolley will reach its lap after the iirst trolley has reached its lap and before it has passed beyond the supplemental conductor, while with the car traveling in the opposite direction the order will be reversed, the trolley upon the line of working conductors not connected with the switch first reaching `its lap, after which its companion trolley reaches first its lap and afterward the supplemental conductor. For example, as the trolleys traveling in the direction of the current approach the laps Z Z', trolley f first contacts with supplemental conductor G with the lapping portion of working conductor U3. After .f is in contact with C3 and before it has passed beyond either C or G, trolley j" contacts with the lapping portion of C2 and maintains its'contact with the lap Z until f has passed beyond the supplemental conductor and the lap Z. When the trolleys approach the laps in the opposite direction, the order of contact is reversed, trolley f reaching its lap first and maintaining contactwith the lap until trolley f has reached in succession its lap and the supplemental conductor and lpassing from its lap before f has passed from its lap or from the supplemental conductor. The magnets which control the switches are wound with two independent coils of wire, the coils being wound in the same direction and insulated from each other. The connections of one coil (hereinafter called coil l are the same as represented in Figs. l and 17. Coil 2 is connected at one end with the supplemental conductor G by a wire gd, and at the other end with the main circuit bya wire cZu2, taking around the switch B4, as shown in Figs. 5 and 1S, short-circuiting switches B and B'. When the trolleys of a motor travcling with the current are in Contact only with opposite sections ot the working conductors, the path of the current is the same as shown in Fig. l. When the trolleyf con tacts with G, the current, after passing through the motor, divides, part following its old course through c'cZ, coil l, and da to A', and part passing vict supplemental conductor G, wire gd, coil 2, and wire daz to A2. Whenthe trolleys embrace C, C', C3, and G, three paths are momentarily open to the current, the two just mentioned and a third through C3, wire 03d', coil l of magnet E', and wire cZot2 to the main circuit.` The latter current will vitalize the magnet D and lift fork B. This stops the current through coil l of magnet D; but the circuit through supplemental conductor Gand coil 2 to main circuit-section A2 is still closed. Then the trolleys embrace the sections C, C2, C', and C3 and the supplemental conductor G, the courses ofthe currents remain the same. When the trolley leaves G, magnet D is cut out of circuit and allows fork B to drop, thereby closing the switch. While the fork is dropping, the circuit is maintained through working conductor C, motor F, workin g conductor G3, wire 03d', coil l of magnet D', and wire cZa.2 to the main circuit. When the trolley has passed IOO IIO

the lap Z, the switchB will have closed, and

the current passes through sections A and A of the normal circuit, wire aci, working conductor C2, the motor, working conductor C, wire ccZ, coil l of magnet D', and wire (Zt2 to section A2 of the normal circuit. When the car is traveling in the opposite direction,

with a two-way switch, .one of the connections from which is through the motor and the other through a local battery traveling with the car to the other trolley, the normal position of the switch being such as to keep the motor in circuit and the battery7 out of circuit. In the formA shown H, Fig. 19, repre-` sents a battery carried bythe car. One pole of this battery is connected with trolley f',

While the other is connected with a contact h, adapted to be engaged by a key I,but normally out of engagement therewith. ,The

trolley .connection f is divided, one part f be ing connected with the key I and the other is thrown into series.
