To all 1.1171. out it nt/u cortcerrt: both directions, the upper bar a of said frame Be it known that I, HENRY A. SEYMOUR, of constituting a support for a trolley-wheel C. \Vashington, in the District of Columbia, The trolley-wheel C is mounted upon a sleeve have invented certain new and useful Imor carrier 1), and the latter is located loosely 5 provements inTrolleys forElectrie Railways; on the bar or support a of the rectangular and I do hereby declare the following to be frame B, so as to have a free sliding move a full, clear, and exact description of the inment thereon, From this construction and vention, such as will enable others skilled in arrangement of parts it will be seen that when the art to which it appertains to make and the car is rounding a curve the trolley-wheel IO use the same. will be permitted to have free lateral move- My invention relates to an improvement in ment, so as to readily accommodate itself to electric railways, and more particularly to the curved trolley-wire and thus be prevented trolley devices therefor, the object of the infrom accidental escape from the latter. vention being to provide simple and efficient It may be found desirable to provide means 15 means whereby to prevent the accidental eswhereby to normally retain the trolley-wheel cape of the trolley-wheel from the wire, especentrally between the ends of the rectangular cially in rounding curves. frame or support when it is running on a lVith this object in view the invention constraight trolley wire or conductor, and for sists in the oombination,with a trolley-pole, of this purpose coiled springs c 0 may be em- 20 an elongated support attached to the upper ployed, as shown in Fig. 1. 7

Figs. 2, 3, 4, 5, O, and 7 are views In the form of the invention shown in Fig. illustrating modifications. 6 the elongated frame 72, employed is some A represents a trolley-pole which may be what similar to the frame B, (shown in Fig. connected with the roof of a car in any de- 1,) but instead of being secured to the trolsired manner. To the upper end of the pole ley-pole its lower bar *6 is adapted to slide in 50 A a rectangular frame B is secured and a sleeve j, secured to the top of the trolley adapted to project laterally from the pole in pole, and the trolleyflvheel 7c is mounted on an arm m, projecting from the upper bar at of the frame. Thus, instead of permitting a lateral movement of the trolley-wheel on its support, as above described, the necessary lateral play is'accomplished by permitting a movement of the trolley-wheel support.

In the form of invention shown in Fig. 7 an arm 0 is pivotally connected to the upper end of the trolley-pole, and to one end of said pivotal arm the elongated frame or support 13 is secured at a point centrally between its ends, or, if desired, the supports shown in Figs. 2 and 4 might be attached to the pivoted arm 0. The free end of the pivoted arm 0 may be provided with a Weight 19 and connected with the end of the car by a cord q for insuring the proper contact of the trolley-Wheel with the trolley-Wire.

Various slight changes might be made Without departing from the spirit of my invention or limiting its scope, and hence I do not Wish to limit myself to the precise details of construction herein set forth.

' Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a trolley-pole, of an elongated support attached to the upper end thereof, a carrier adapted to travel on said support and a trolley-wheel mounted on said carrier, substantially as set forth.

2. The combination With a trolley-pole and an elongated support at the upper end thereof, of a carrier adapted to travel on said support, a trolley-wheel mounted on said carrier and means for normally maintaining said carrier and trolley-Wheel in and automatically returning them to their position centrally between the ends of said elongated support, substantially as set forth.

3. The combination With a trolley-pole, of an elongated support attached to the upper end thereof, said support being inclined in both directions from the center, a carrier mounted to travel on the support, the opening through said carrier being enlarged at both ends and a trolley-Wheel mounted on said carrier, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

HENRY A. SEYMOUR.
