SPECIFIGATION forming part of Letters Patent No. 532,448, dated January 15, 1895. l Application filed March 30. 1894. Serial No. 505,745- (Nomodel.)

To all whom itl may concern:

' Be it known that I, WILLIAM TAsKER DU# vLANY, .T r., a citizen of the United States, residing at New York city, in the county of New York, State of New York, have invented certain new and useful Improvements in Electric-Railway-System Conduits, of which the following is a specification, reference being had therein to the accompanying drawings.

The objects of my improvements are to provide in connection with two conductors or trolleywires placed within a conduit and insulated therefrom, a trolley standard containing within the wearing plates, at metal plate conductors made in series with fuse blocks or cut outs above and also under the points of contact'of the standard with the slot of the conduit, so that if the wearing plate on one side of the standard becomes cut while a car carrying the standard makes one of its trips, the plate conductor on the opposite side will continue to transmit power to the motor of said car. l

Another object is to provide the portion of the standard within the conduit with water and mud detlecting shields to protect the fuses of the plate conductors and the journals of the trolley and prevent short circuiting.

Another object is to provide a cross fuse connection between conductor fuses g g to connect them so that if a section conductor in the conduit becomes grounded or dead on one side, and the wearing plate Von the opposite sideof the standard becomes worn through and ground7 that the said cross fuse connection becomes operative and supplies the necessary current to operate the car motors by crossing the current from right to left in the conductor plates and vice versa.

Another object in making cross connection between fuses g g is to'supply four paths for the current to travel in case of accidents to tb o standard and conduit system before reaching ,switches for the car: namely, up either one side or both sides of standard if no fuses are burned out and up standard from right to left through cross fuse if the section fuse of conduit on left side and the lower fuse g and the upper fuse h on the right side of standard are burned and vice versa.

Another obj ect is to divide the conduit system into sections; said sections being connected through suitable fuses to their respect- Ive feeder conductors and said feeders are Yconnected at their switch board terminals with, and made to pass through ampere meters to easily localize from said terminal any defect or ground on a section or part of the system.

I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is a transverse vertical section of a` trolley standard constructed in accordance with my invention,said standard having only one of the trolley arms mounted thereon. Fig. 2 is a side view of the lower portion of the trolley standard. Fig. 3 is a top view of the standard. Fig. 4 is atop view of the front (or rear) bar of the standard with portions of the wearing plates and insulated conductors. Fig.. 5 is a front View of the lower portion of the series of plates constituting the conductors on one side ofthe standard, with the fuse blocks uniting two plates of said series. Fig.

6 is a transverse vertical section of the lower portion of thevstandard showing a cross fuse connection between the fuses g g to illustrate the method of`orossing the current from the lower conducting plates c2, to the upper conducting plates e inthe standard, this modified construction being preferred for the purpose of crossing the currentin saidstandard if one or the other of the section fuses is burned out. Fig. 7 is a transverse vertical section of the track showing the two trolley wire conductors withinv the conduit and the feeder cables of the conductors. Fig. 8 isaplan view of a series of sections of trolley conductors, each Lsection being shown connected with a switch board terminal or ampere meter. Fig. 9 is a perspectiver view of the conduit cleaning brush t0 be attached to the lower end of the Standard.

In said drawings A representsfthe trolley standard, and B the trolley journal bearings that are projecting from the sides of the standard adjacent to the bottom thereof and aresecured thereto by means of llanged cap plates a. The standard consists of side plates kthat are bolted to the front and rear bars K, each of said bars being provided with a IOO tongue, as shown in Fig. 4 that extends some distance between the plates k, and to which the latter are bolted, the space between the tongues of the bars K and the side plates 7c constituting a rectangular conduit for the reception of the pair of flat conductors e e2 and their mica insulators f and f 2. The central insnlatorf separates the conductors e and e2 and the insulators f2 protect them from contact with the side plates 7c and from contact with the tongues of the bars K. The inner end of cach trolley journal B is provided with a flanged head to permit it to be secured to the plate conductors e2 by means of the cap plates a; but upon each journal B and around the flange of; its head is placed a sleeve b of insulating material that protects it from con-V tact with the side plates 7a and with the capplates c.

Each conductor consists of two lengths e and c2 that are united together by means of fuses (cut outs) g and g2 of any suitable construction. as consisting of short lengths of wire g3 having one end secured to the central portion of the conductor e by wrapping said portion around said end, while the opposite end is embedded in the easily fusible plug g secured to the end of the opposite section e2 of the conductor. The location of the fuses g is shown to be at a short distance above the trolley journals B, and the location of the cross fuse g2 is shown in Fig. 6 connecting fuses g to each other. They may be at a higher point but said point must be below the location of the wearing plates 7a2, and beneath the shield J. Said plates 7a2 of the standard are located thereon when in use on the level of the edges of the slot of the underground conduit.

The upper end ot' the standard is received in a metal head-block P, said block having pendent therefrom a rectangular sleeve p vthrough which bolts p2 are made to pass horizontally to engage with the bars K of the standard and fasten the trolley standard to head block P. The head of the block P has bolts p3 passing vertically therethrough to secure it to the frame of the car. The head block of the standard is also provided with fuses (cut outs) 7L nearly similar to the fuses g, the electric current passing thence through wires h2 to the switches and motor of the car.

To prevent mud and water that may be descending upon the standard from reaching fuses g g or the trolley journals and their arms and producing a short circuit, shields J are bolted to the side plates 7c of said standard a short distance above said trolley journals and fusesg g. Said shields consist of arches formed of angle bars bent suitably with their outer iiange turned up nearly parallel with the standard, and the lower portions of said arches extend a suitable distance in front and rear of the standard.

The trolley arms d are pivotally mounted upon the outer end of each journal B and are They are shown in this instance retained thereon by means ol' a washer n and nui n2. Each trolley arm (l is provided with two grooved rollers d2 connected in tandem to better facilitate their passage over the ends of each independent section conductor in the underground conduit without interrupting the electric current.

To keep the rollers d2 normally pressed upon the conductor wire, a wire spring C is coiled upon the end ot each journal B andhas one end secured to said journal while the opposite end bears upon the inner end of each arm d.

Fig. 9 shows a t'an shaped brush Q having a metal back Q2 to be bolted to the bottom or lower end of the standard between its two plates 7c projecting from the bottom of said standard beyond its conductors for the pnr-,

pose of sweeping (cleaning) the dirt or mud out of the conduit and depositing the same in catch basins, not shown, situated at suitable distances apart and having conduits connecting'both tracks, one with the other. Said conduits are to have a man hole plate between said tracks for the purpose of better facilitating the removal of the same and to prevent clogging up of the conduits by the dirt, dsc. The back of the brush has openings a' to receive bolts a2 made to pass through them in fastening the same to the plates K of the standard A.

The trolley conduit D has plates D2 on top thereof at a suitable distance apart to provide between them the slot for the passage of the standard A; and said conduit has laterally extended bars D3 that connect it with the rails e3 of the track. Said bars rest upon yokeplates M to which are attached brackets m, the inner ends of which enter the conduit and support insulators m2 for the trolley conductors N. Said brackets also carry on suitable standards and insulators m3, the distributing feeder conductors N2 that carry the electric current from the power station to each section ofthe trolley wire ofthe underground system. For this purpose the yoke-plates M have large perforations m4 on each side of the conduit. They have also openings m5 that may be used for the passage of properly insulated telegraph and electric light wires or cables. The conduit D is provided at suitable distances apart with drainage pipes d4 that are connected with sewers d5.

To facilitate the detection of any defect in any of the sections of the trolley conductors N each conductor N is connected by means of its feeder conductor N? and through suitable fuses at their switch board terminal, with, and through ampere meters F preferably love-fed in the power-house or office of the railway" w line, and thus prevent any car from being stalled for any great length of time upon any part of the line as the defect can be immediately perceived and located and repairs be promptly made by the employs.

Having now fully described my invention, I claim- IIO Mw.. i n
