JOSIAH L. BLAOKWELL, OF NEW YORK, N. Y.
ELECTRIC-RAILWAY TROLLEY.
SPECIFICATION forming part of Letters Patent No. 389,282, dated September 11, 185 8.
Application filed August 9, 1888. Serial No. M82369.
To all whmn it may concern.-
Be it known that I, JOSIAH L. BLAOKWELL, a citizen of the United States, residing at New York. in the county of New York, State of New York, have invented certain new and useful Improvements in ElectrieRailway Trolleys, of which the following is a specification.
My invention relates to contact devices for maintaining electrical connection with suspended supply-conductors, and as illustrated in the accompanying drawings, wherein- Figure 1 is a transverse section on the line or y of Fig. 2. Fig. 2 is a transverse longitudinal section, and Fig. 3 is a detail showing different positions of the contact-piece.
It has been found that when a trolley is employed to travel along a suspended supplywire of an electric railway and lead the current therefrom to a vehicle the movement of the trolley, especially at high speed, communicates a vibration to the wire which is extremely disagreeable to hear, and which extends for a long distance in advance of the vehicle. To obviate this annoyance I have provided a trolley with bearing-wheels of rubber, wood, or other non-resonant material, and provided small sliding brushes or shoes, which maintain the electrical connection.
In the accompanying drawings, A represents a supply-wire.
B is the frame of the trolley.
(N0 model.)
C C are wheels, of wood or rubber, jonrnaled in frame B.
D D are transverse pins extending between the opposite sides of frame B, each provided with a loosely-hung contact shoe, E, adapted to travel upon conductor A. Each shoe E has at its upper end a long loop passing around pin D, so that, as shown in Fig. 3, its position may be automatically reversed with reversal of the direction of movement of the trolley.
F is a traveling link or wire of any wellknown description.
\Vhat I claim as new, and desire to secure by Letters Patent, is
1. The combination, with a suspended supply-wire for an electric railway, of a contacttrolley therefor having a wheel of non-resonant material, and a supplementary contact device for maintaining the electrical connection.
2. In a contact-trolley for an electric railway, the combination, with frame B and a bearing-wheel, O, of the controlling contactshoe E, having a loop or slot connection atits upper end with frame B, whereby it is automatically reversed with a change in the direction of movement of the trolley.
