JOHN C. HENRY, OF WESTFIELD, NEW JERSEY.

OVERHEAD ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 501,009, dated July 4, 1893.

Application filed September 2'7, 1889. Serial No. 325,244. (No model.)

county, New Jersey, have invented certain new and useful Improvements in Electric Railways, of which the following is a speci-' fication.

My invention comprises certain improvements in electric railway systems which I will first describe with reference to the accompanying drawings, in which- Figure 1 is an elevation of one post and portion of guy-wire of my system. Fig. 2 is a horizontal sectional view of the post on the line 2-2, Fig. 1. Fig. 3 is a similar view on the line 3-3, Fig. 1. Fig. 4 is a similar view on the line 4-4:, Fig. 1. Fig. 5-is a side View of one end of an electric car, and the traveling trolley or contact-device, attached thereto. Fig. 6 is a detached end view of a trolley, line-conductor and hanger. Fig. 7 .is a plan view of a circuit.

In carrying my invention into practice, I bury in some convenient position, parallel with the track, a large continuous insulated conductor (feeder) preferably of the form and in the position shown in Fig. 1. The conductor 1, here shown, is an old worn out railroad raila cheap material which can be obtained ready-made and which is of sufficient size to convey a large current. I surround it with asphaltum 2, or other insulating material, taking first the precaution to place under the conductor, glass or other hard insulating supports 3, to prevent the sinking of the conductor 1 in the asphaltum, and insure insulation below. The whole is inclosed in a wooden box 4. I thus provide a conductor of large carrying capacity, thoroughly insulated, Posts or poles are arranged along the line of roadway to support the working conductor or conductors over the track. These posts I construct of light weight and calculated to withstandstrain, transverse of the roadway, but without reference to strain longitudinal of the track. Thus the pole is made up of gas or other wrought iron pipe 5, on which are cast ribs 6 and braces 7, and

' when the post is set in the ground its braces are as shown-placed transverse of the roadway. Flanges 8 and 9 of considerable area in the position shown on the front and rear of the-post at and near its bottom, serve as deadmen or splay-feet to maintain the post upright. I

The guy-Wire (cross-wire, rod or cable from which the working conductors are suspended) is shown at 10, Fig. 1 supported at the sides of the street by insulators 11 at the top of the posts 5. On these guy-wires are supported adjustable and flexible hangers. Each hanger consists of a sleeve 12 through which the guy-wire passes and each is adapted to be fixed at any position on said guy-wire over the track by set screw 13. Pendent from the sleeve 12 is an arm 14 carrying two crimped sheet metal arms 15 which carry the working conductors 16. The working conductors 16 are flat and, for a straight portion of the road, consist of horizontal ribbons of great tensile strength adapted to receive, and constitute an aerial track for, a trolley or contact-device of the construction shown in Fig. 6. Here 17 is the frame of the trolley which moves along under the working conductor and embraces its bottom and' sides. This frame is supported from the working conductor by contact and Wear plates 18.

Lubricators 19, 19 are supported on the contact-plates 18 to lubricate the sliding contact surface of said plates. This expedient increases the life, both of the contact plates and working conductor, but the contactplates are, as shown, removable so that they may be replaced by fresh ones when worn. By keeping the working conductor constantly lubricated also and covered with oil, the adherence of moisture and ice thereto is prevented and a good contact is always assured. This matter is the subject of an application filed by me the 13th of August, 1890.

As seen in Fig. 5, the trolley is sectional, its two parts being hinged together at 20, so that-the trolley of any desired length will more readily conform to the curves and undulations of the working conductor as it is pulled along the same. The trolley is connected to the car by flexible conductor 22 and mast 23. g The latter is mounted in a socket 24 at bottom and has a spring clamp 25 at its mid-length, so that the mast may be readily movedfrom end to end of the car or to another car when it is necessary. The spring clamp 25 is in circuit with the motor, and automatically completes the circuit to the working conductor by contact with the terminal band 22 of tow -line 22. To strengthen the mast the wire is wound around it from the top down to band 22.

Referring now to Figs. 1 and 7, it will be seen that the main feeding conductor 1 is connected at intervals to the guy-wire 10 by insulated branch feed conductors 10, passing up through the hollow posts 5. The posts are staggered on opposite sides of the street as shown in Fig. 7. Aless number of posts may be used thus than in the ordinary way as each supports the working conductors at two points. The guy-wire 10 is continuous, passing around insulators 11 at the tops of posts 5 and is bent diagonally back and forth across the track. It supports from each stretch a pendent hanger for the working conductor or conductors and thus places the latter in electrical connection with the feeder 1 and one pole of dynamo 24. The other pole of the dynamo may be connected to the track-rails which may serve as the return conductors from the car motor or motors. By forming the guywire continuous I mean that it affords a continuous pathway for the electric currentwithout regard to the mechanical continuity of the wirethough it is obvious that the best result will be obtained ordinarily by using a continuous wire bent from post to post of one strip except for necessary splicing together of its lengths. By the diagrammatical view Fig. 7, it is seen that the dynamo current is divided between the working conductors, the overhead zig zag. conductor and the underground feeding conductor. The zig zag wire thus forms one of the feeding conductors as well as affording branch conductors between the underground feeder and the working conductor. In Fig. 7 also, I have shown staywires 26 for supporting the tops of the posts 5 from adjacent buildings or structures. It will now be seen that the electric circuit is from the stationary dynamo or other source of electricity through main feeder 1 to the several branch feed wires 10, guy-wires 10, hangers 12, 1 1, 15, working conductor or conductors 16, trolley 18, 17 and tow-line 22 to the car-motor, whence it passes by the rails or the return conductors back to the dynamo.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
