E. T. BENNINGTON CURRENT COLLECTOR Filed Sept. 5, 1924 27 ,2 1O 27 La ue n73 Patented Jan. 26, 1926 UNITED STATES 1,570,933 PATENT OFFICE.
EARL T. BENNINGTON, OF WILIIOUGHBY, OHIO, ASSIGNOR TO THE CLEVELAND CRANE & ENGINEERING COMPANY, WICKLIFFE, OHIO, CORPORATION OF OHIO.
' CURRENT COLLECTOR.
Application filed September 5, 1924. Serial No. 736,040.
To all whom it may concern:
Be it known that I, EARL T. BnNNINcroN, a citizen of the United States, residing at Willoughby,. in the county of Lake and State of Ohio, have invented a certain new and useful Improvement in Current Collectors, of which the following is a full,
clear, andexact description.
This invention relates to current collectors such as employed for conducting current from a conductor wire or rail to the operating motor of an electrically propelled vehicle, andmore particularly to current collectors for use in various kinds of overhead carrier systems such as monorail, vtelphers and cranes.
It is the object of the invention to provide a current collector which is simple in construction,.which is economical to manufacture and which is efficient in. operation.
More specifically it is an object of the invention to provide a current collector which maintains at all times a firm contact with the conductor from which current is taken so that it is practically sparkless in operation even when used in connection with badly aligned conductor rails.
A further object is to provide a current collector which is so mounted that the trolley wheels are held firmly in engagement with the conductor at all times so that'the collector will not jump out of engagement with the conductor wire or rail. I
With the above and other objects in view the'invention may be said to comprise the device as illustrated in the accompanying drawings hereinafter described and particularly set forth in the appended claims, together with such variations and modifications thereof as will be apparent to one skilled in the art to which the invention ap pertains. y Reference should be had to the accompanying drawingsforming a part of thisspecification in which Fig. 1 is a side elevation of a carrier supportedfrom an overhead rail and receiving current for operat- '.ing the mechanism thereon from an overhead conductor rail parallel with the supporting track; Fig.2 is a side elevation on an enlarged scale of the current collector, a portion being broken away to show the yieldably mounted trolley supporting post in section; Fig. 3 is a topplan view of the trolley wheel support; Fig. 4 is a transverse section on line it-'4: of Fig. 2; Fig. 5--is a side elevation of a trolley wheel.
Referring to the accompanying drawing, Fig. 1 shows an overhead carrier 1 supported from an overhead track 2 and receiving current for operating the mechanism thereof from a conductor rail 3 which extends parallel with the supporting rail 2. The specific construction of the carrier and of the operating mechanism thereon is immaterial in so far as the present invention is concerned, the present invention relating solely to the current collecting device by means of which current is conveyed from the conductor rail 3 to the mechanism upon the carrier 1. v
The current collector is carried by a rigid arm 1 integral with the frame carrying one of the carrier supporting wheels. Rotatably mounted in the arm 1 is a horizontally ex' tending shaft or arm 4 which carries at its outer end a socket member 5 from which the trolley wheels are supported. The socket member 5 has a laterally extending sleeve portion 6 which is fixed upon the outer end of the arm 4 by means of a transverse pin or rivet 7 whereby the socket member 5 is rig idly secured to the arm 4 to be turned therewith. At right angles to the sleeve portion 6 the socket member 5 has a clamping sleeve 8 which is split along its outer side and provided with outstanding ears 9 which receive a clamping bolt 10. Rigidly clamped within the sleeve 8 is a tubular insulating member 11 which is closed at its lower end, the insulating member 11 being formed of suitable insulating material. Rigidly secured within the insulating tube 11 is a metal tube 12, preferably copper tubing which extends to the lower closed end of the insulating 95 tube 11 and projects somewhat above the upper end thereof; Slidably fitting within the tube 12 is a second metal tube 13 which may also be of copper and which forms the supporting post for the trolley wheels. 9 Within the upper end of the tubular post 13 is a filler 14 of insulating material which is engaged by the upper end of a compression coiled spring 15 which rests at its lower end upon a metal washer 16 upon the bottom of 195 the insulating member 11. The compression spring 15 forms a yielding support for the post 13 and acts at all times to press the trolley against the conductor rail 3.
The tubular supporting post 13 slotted at diametrically opposite points at its upper end and the opposite walls are flattened to provide spaced ears 17 which receive between them the rigid trolley supporting arm 18. The trolley supporting arm is formed of two side bars 19 which have central depressed portions 20 which are secured together in, Contact between the ears 17 of the supporting post by means of a transverse pivot pin 21. The outer ends of the side bars 19 are spaced apart and carry transverse pintles 22 upon which the grooved trolley wheels 23 are rotatably mounted. The pivotal mounting of the trolley wheel carrying arm 18 permit-s relative vertical movement between the front and rear trolley wheels so that in passing over a joint in' the conductor railv 3 or over any irregularity in the rail, the trolley wheels will both be maintained in. engagement with the rail. The coiled spring 15 acting to press the supporting post 13 toward the conductor rail applies substantially equal pressure to both trolley wheels at all times so that irregularities in the conductor rail will not cause the trolley wheels to be thrown from the is connected so that the post supporting spring does not have current pass therethrough. For receiving current from the trolley wheels, the projecting upper end- I of the fixed metal tube 12 has a clamp 24 secured thereon, the clamp 24 being in the form of a metal strip, preferably copper encircling the tube 12 and clamped thereto by means of a bolt 25. The two trolley wheels 23 are connected to the clamp 24 by means of flexible conducting wires or pig tails 26 which have terminals at one end beneath the head and nut of the bolt 25 and the terminals at the opposite ends secured to the ends of the pintles 22 by means of binding screws 27. The current for operating the mechanism on the carrier 1 is taken from the clamp 12 by a suitable conductor such as 28 in Fig. 4.
Having described my invention, I claim: 1. A current collector comprising a supporting member mounted to swing laterally and having a socket substantially at right angles to the pivotal axis thereof, apost slldably fitted in said socket, a spring acting upon said post to yieldingly press the same outwardly with respect to the socket, a rigid member pivoted mtermediate its ends to said post and trolley wheels carried by said member on opposite sides of the post.
