ELECTRIC-CAR TROLLEY.

SPECIFICATION forming part Of Letters Patent NO. 564,395, dated July 21, 1896. Application filed October 31, 1895. Serial No. 567,5974. (N0 model.)

To aZZ 1071,0717, it may concern.-

Be it known that 1, WILLIAM H. RUSSELL, of Newcastle, in the Province of NewBrunS- wick and Dominion of Canada, have invented certain new and useful Improvements in Electric-Oar Trolleys; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part hereof.

My invention, which will be hereinafter fully set forth and claimed, relates to trolleywheels for overhead wires for electric cars.

The object of my invention is a trolley v wheel carrier or bearing that shall make the wheel less liable to be thrown off the wire.

Figure 1 is a side elevation of my improved trolley, shown on the trolley-arm. Fig. 2 is a front view of the same without the trolleyarm and without guard. Fig. 3 is a rear view of the same. Fig. 4 is a vertical section of the same through the center parallel to Figs.

2 and 3. Fig. 5 is a vertical section of the same through the center parallel to Fig. 1. Fig. 6 is a transverse section of the same on line 6 6, Figs. 2 and 3; and Fig. 7 is a top view of the guard, taken approximately at a right angle to the trolley-arm.

A frame of three parallel tubular bearings, a small one, A, 011 each side and a thicker and longer one, A, in the center, is formed by connecting them rigidly by two cross-pieces A, one at each end of the short tubes, allowing the long one to project below. To this frame is rigidly secured a hub B by means of a plate I) integrally formed therewith, and which is bolted or screwed to the lower cross-piece A and to two intermediate cross-pieces A, said hub forming a socket for convenience of attachment of the frame to the end of the trolley-arm T. A wheelfork is formed of a cross-head C with two tines or arms C, in which the trolley-wheel thus between arm and wheel.

lock-nut d, a central slide D, adapted to slide freely in the central tubular bearing A. This central rod .is of the same thickness as the side rods, although 7 the bore of the central tube is larger, but it is longer, to suit the greater length of the bearing. Upon said central slide-rod is coiled a spiral spring D, abutting at the upper end against the locknut d and at the lower end against a collar a, secured to the end'of the hearing A and having a bore reduced to the diameter of the slide-rod D, for which it forms a bearing or guide. A collar or lock-nut d is secured upon the lower end of said central slide-rod D to prevent said rod leaving its bearing.

. It will be seen that the spring D extends into the barrel or central tube A and coin 'trols the position of the fork O O relatively to the frame A A A, which is fast on the trolley-arm T, causing the fork to slide freely on the frame and forming a yielding or elastic connection between frame and fork, and This elastic connection will prevent, or at least largely help to prevent, the wheel V leaving the conductor WV.

To bridge over the angle between the trolley-arm T and the arms 0' of the wheel-fork, or rather the wheel 7, a guard G is provided, as shown in Figs. 1 and 7. This is a light rod having one end g forked and the fork ends pivoted to a sleeve or clip G, placed upon the trolleyarm and the other end formed into a long hook g, adapted to hook and slide upon a bail G, which is rigidly secured to the fork-arms C in an upwardly and forwardly slanting position. Should the trolley leave the conductor WV and run against a cross-wire, the guard G will cause the latter to slide over the wheel W and prevent it entering the angle'formed by the trolley-arm and the bearing A B O and wheel V, while the hook g, sliding upon the bail G, will allow the guard G to yield with the spring hearing.

I claim as my invention 1. The combination with a trolley-arm of a frame rigidly connected with saidarm and consisting of three tubular bearings connected by cross-pieces, a fork consisting of a cross-head having arms or tines in which the wheel is journaled and three slide -rods adapted to slide in the tubular bearings, a spring coiled upon the central rod and pass ing into the central bearing of larger bore and greater length, a collar at the end of said central bearing forming a bearing for the rod and stop for the spring, a trolley-wheel journaled in the arms or tines of the fork, a guard-rod forked at one end and hooked slidingly at the other, a sleeve or clip upon the trolley-arm to which the forked end of the guard-rod is pivoted and a bail rigidly secured to the arms of the Wheel-bearing passing around the trolley-wheel in front and supporting the hooked end of the guard, substantially as set forth.

2. The combination with the trolley-arm of a frame rigidly connected with said arm and consisting of three tubular bearings connected b'y cross-pieces, a fork consisting of a cross-head having arms or tines in which the wheel is journaled and three slide-rods adapted to slide in the tubular bearings, a spring coiled upon the central rod and passing into the central bearing of larger bore and greater length, a collar at the end of said central bearing forming a bearing for the rod and stop for the spring, and a trolley-wheel journaled in the arms or tines of the fork, substantially as set forth.

The combination of two parallel slidebearings connected by cross-pieces, a springbarrel between said bearings, a hub or socket the central barrel and a collar at the end of said barrel forming a stop for said spring and a bearing for said slide, substantially as set forth.

4. The combination of a frame consisting of parallel tubular bearings rigidly connected transversely, a spring-barrel between said bearings, means of connecting said frame to the trolley-arm, a cross-head having rods slidingly supported in the tubular bearings, a central rod on said cross-head passing into the spring-barrel, a spring upon said central rod bearing against a tubular collar at the end of the spring-barrel, means of contact with the conductor on said cross-head a sleeve or clip on the trolley-arm, a guard-rod pivoted to said sleeve or clip and means of supporting the upper end of said guard-rod in line with the contact-piece substantially as set forth.

In testimony whereof I have signed in the presence of the undersigned witnesses.

XVILLIAM H. RUSSELL.
