I UNITED STATES PATENT OFFICE.
WVILLIAM O. MILLER, OF ALBANY, NEIV YORK.
TROLLEY.
SPECIFICATION forming part of Letters Patent No. 432,063, dated July 15, 1890.
Application filedApril 8, 1890. Serial No. 347,099. (No model.)
To all whom it may concern.-
Be it known that I, \VILLIAM C. MILLER, a citizen of the United States, residing at the city and county of Albany, State of New York, have invented a new and useful Trolley Attachment for use on Electrical Railway-Oars,
of which the following is a specification.
My invention relates to improvements in trolleys; and the objects of my invention are to provide, first, an attachment to a trolley at tached to an electric car, by means of which a sliding contact is made with a trolley-wire; and, second, to provide a means for separating ice or sleet from the trolley-Wire, and at the same time furnish such aconnection with the wire that the movement of the car will not be retarded. I accomplish these objects by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 shows a trolley provided with my invention in contact with a trolley-wire; Fig. 2, an elevation of the connecting-bar; Fig. 3 a front elevation, Fig. & a side elevation, and Fig. 5 a rear elevation, of my invention.
Similar letters refer to similar partsthro ughout the several views.
T represents an ordinary forked trolley. Between the tines Y of the forked trolley T, I place the holder II, held in position by means of thebolt B, passing through the holder and tines of the fork near their end and prevented from longitudinal movement by in cans of the pins 1. Thelowerportion of the holder II is provided with a metal plate h, which extends beyond the tines of the fork Y and presses against said tines, thus increasing the conductivity. The holder His provided with the sleeves S, one placed near the upper portion of the holder and the other in contact with the plate h. Into the sleeves S, I place the metallic connecting-bar M, held in position by means of the thumb-screw V in one of the sleeves S. The metallic connectingbar M is slightly curved above the sleeves S in the direction toward which the car moves and provided at its end with a groove G, cut to fit the trolley-wire. The metallic connecting-bar M is adjustable in the sleeves S, and may be readily removed from the sleeves and replaced by another, when desired. The holder H, through which the bolt B passes, may be very quickly removed, in order that a trolley-wheel may be substituted therefor in the fork. It very frequently occurs that the trolley wire becomes coated with ice and sleet, which forms an obstruction to the ready passage of the electricity from the wire to the motor when a trolley-wheel is used, and it is particularly for the purpose of removing this obstruction that I have constructed my attachment. I find, however, that the sliding contact provided by my metallic connecting-bar with the trolley-wire is quite as practical and performs its function of transmitting the electric fluid from the wire to the motor quite as satisfactory as the trolleywheel nowin use and I therefore do not limit myself to the use of myinvention for removing obstructions from the wire.
IV hen a trolley is provided with my invention, the metallic connecting-bar M is placed in contact with the trolley-wire, the wire fitted in the groove G at the end of the connectingbar, the plate It at the lower portion of the holder II is pressed firmly and securely in contact with the sides of the trolley-fork, and the electric current connects with the trolley not only through the bolt B, which passes through the holder II, but also through the plate h, connected to the holder and in contact with the trolley.
IVhatI claim as my invention, and desire to secure by Letters Patent, is
1. A trolley provided with a metallic bar having a groove cut at one end, in which the trolley-wire passes, said metallic bar being connected to a trolley by means of a bolt passing through the fork of the trolley, substantially as described, and for the purpose set forth.
2. In a trolley, the combination of a holder secured within the fork of a trolley and provided with a metallic plate in contact with the sides of a trolley, with a metallic bar secured to said holder having its end in contact with the trolley-wire, all substantially as de scribed, and for the purpose set forth.
3. The combination of an overhead trolley; wire with an under-riding metallic bar making a sliding current collecting connection therewith, said bar attached to a trolley-arm, all substantially as described, and for the purpose set forth.
