SPECIFICATION forming part of Letters Patent N0. 760,330, dated May 17, 1904.
Application filed May 28, 1903. Serial No. 159,200. (No model.)
To all whom it may concern.-
Be it known that I, J AMES FURGASON, a citi zen of the United States, residing at Montour Falls, in the county of Schuyler and State of New York, have invented a new and useful 'lrolleydole, of which the following is a specilication.
This invention relates to trolleys; and the object to be attained is to provide a trolley which will maintain a constant contact with the conductor, so as to materially reduce the liability of the arc being formed, which results from the usual type of collector.
Another object of the invention is to provide means whereby the harp will be free to swing, so as to remain in contact while rounding curves.
Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims, it being understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the sp1r1t or sacrificing any of the advantages of this invention.
In the drawings, Figure 1 is a side elevation of the lnvention, the pole being shown 1n section; and Fig. 2 is a fragmentary view, partly the harp 5 is limited by a pair of depending radial stops, (designated as 7 and 8,) between which an abutment 9 is arranged and carried by the frame. The abutment 9 is illustrated as being in the form of a bolt projecting through the forked frame 2, and the stops 7 and 8 are provided with flat sides to contact with the abutment.
The flat springs 10, carried by the inner sides of the arms of the harp, have openings through which the shaft 16 projects, permitting the free ends of said springs to bear against the ends of the wheel, whereby rattling-is prevented.
11 designates a ring which is connected to the harp and adapted to receive one end of a rope whereby the trolley can be moved out of contact with the conductor.
The swinging connection for the harp permits the wheel to assume any position to relieve any resistance to which a device of this character would be subjected, thereby efficiently preventing the breaking of the contact between the wheel and the conductorwire.
I claim 1. Thecombination of a trolley-harp comprising agstrip bent to form parallel arms and an intermediate loop,a forked pole, a pin pressing through the forked pole and through the loop, threaded pins carried by the loop and a stop-pin carried by the pole and interposed between the pins.
2. The combination with a trolley-liar p comprising a strip bent to form an intermediate loop, and parallel wheel-carrying arms, a bifurcated pole, and a connection between the harp and pole.
In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
JAMES FURGASON.
