DANIEL E. SHOOP, OF TURTLE CREEK, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO JOHN F. BAXTER, OF PITTSBURG, PENNSYLVANIA.
ELECTRIC-RAlLWAY APPLlANCE.
SPECIFICATION forming part of Letters Patent No. 654,105, dated July 1'?, 1900.
Application tiled December 9, 1899. Serial No. 739,788. (No model.)
To all whom, t may concern,.-
Be it known that I, DANIEL E. SHooP, of Turtle Creek, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Electric-Railway Appliances, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a diagrammatic plan View illustrating my improved trolley and system of overhead conductors adapted to be used in connection therewith. Fig. 2 is a side elevation of the trolley and a portion of the overhead system. Fig. 3 is an end elevation showing a double-track system and a cross-line.
The objects of myinvention are to provide a simple and effective trolley mechanism and a system adapted to be used in connection therewith, whereby the tendency of the trolley to leave the wire is reduced to a minimum. I also dispense with the necessity for the strong springs used upon under-running trolleys, whereby the contact between the trolleywheel and the conductor is maihtained and which when the trolley runs off the conductorwire damages the span-Wires and often breaks the conductors.
My invention is designed to overcome these and other difficulties and provide an overrunning trolley in conjunction with a system of overhead wires especially adapted to be used in connection therewith, and my invention also reduces the wear upon the parts,
and hence repairs and cost of maintenance.
In the drawings, 2 represents the conductors of an overhead electric system supported from span-wires 3 by hangers 4, said hangers being formed with a shank 5, an outwardlyextended arm 6, and an upwardly-extending portion 7, to which the conductor-wire 2 is:
secured.
At crossings a modified form of hanger 4E is used, whereby the conductors 2', crossing the conductors 2 at an angle, are placed at a different level, and a gap 8 is made so as to provide for the passage of the trolley-pole 10, and said hanger 4: has a shank 5', which is made so as to permit the trolley-wheels 11 to pass through. The hangers 4c are provided with outwardly-extending portions 6 and the upwardly-extending portion 7', to which conductor 2' is secured.
The trolley-pole 10 is provided, preferably, witha pair of wheels 11, mounted at right angles to the overhead conduction-wire in suitable bearings at the free end of the pole 10, which is placed betweeh them. This pole is hinged at 12 to lugs or ears 13, extending upwardly from a base 14, rotatably secured to the top of the car by a stud or bolt l5. The base 14 has secured to it a spring 16, which extends between said base and the trolleypole 10, to which it is secured by a suitable clip or fastening. The trolley-wheels run upon the upper side of the conductor-wires 2 or 2', and the wheel which is in contact with the wire, being located at one side of the pole lO instead of centrally, passes freely over the conductor, the extension 6 6 of the hanger giving the requisite clearance for the wheel l1.
By using an overrunning trolley I am e11- abled to use a comparatively-light spring 16, as the weight of the trolley-pole tends to preserve contact, it only requiring a light pressure to give the required contact and in case of the trolley leaving the wire to give a quick downward action, and thus prevent any possible injury to the overhead system.
By being able to use a light spring the wear upon the conductor and trolley wheel is lessened to a great extent and the necessity for repairs is lessened and the cost of renewal is greatly reduced, as only enough pressure need be maintained in order to insure proper electrical connection.
Should the trolley become displaced or it is desired to remove it, it may be done by the rod 17 attached thereto.
By the use of. two trolley-wheels the car is enabled to run in either direction by merely swinging the trolley around, and their close juxtaposition, as shown, permits of their easy passage over or through the cross wires, switches, &c.
The system I have devised of overhead wires and supports permits my improved trolley to be used under all conditions, as the brackets are designed to permit the unobstructed `passage of the trolley wheel and pole.
The operation from the foregoing descripf tion is apparent, and its advantages willV be appreciated by those skilled in the art and are cognizant of the diculties of present overhead constructions `and underrunning trolleys;
I am aware that it is old to use a plurality of trolley-Wheels in tandem, and I do not wish to be understood as claiming that form of device, since the same is radically dier-- ent from the idea of my invention as expressed in the claims;
Many changes will suggest themselves without departing from the spirit and scope of my invention, since I claim--Y 1. The combination with an overhead electric system, having its conducting-wires supported from beneath, of a trolley mechanism comprising a pole having at the free end thereof two trolley-wheels having a common center of rotation, adapted to engage alternately the upper side of the conductor-wire; substantially as described."
2. The combination of an overhead electric system, having its conducting-wires support# ed from beneath, of a trolley mechanism, and
comprisinga pole havingat the free end there-l of; and located at one side", a trolley-wheel adapted to engage the upper side of the con In testimony., whereof I have hereuntosetw 4o my hand.
