EDVARD M. BENTLEY, OF NEY YORK, N. Y.
ELECTRIC RAILWAY.
SPECIFICATION forming part of Letters Patent No. 426,580, dated April 29,' 1890.
Application iiled January 20,1888. Serial No. 261,357. (No model.)
To a/ZZ whom, it may concern.-
Be it known that I, EDWARD M. BENTLEY, 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 Electric Railways,
' of which the following is a specification.
companying drawings, wherein-- Figure 1 is a transverse section through a contact or junction box. Fig. 2 is a diagram of the connection at two successive junctionboxes. Fig. 3 is a plan of the apparatus on a curve. Fig. e is a plan of a junction-box. Fig. 5 is a section on the line 5 5 of Fig 4, and Figs. G and 7 are respectively end and side views, showing the means of connecting the contact-conductor to the car.
In the drawings B is the main supply-conductor, which is completely inclosed and insulated except at intervals of about fifteen feet, where there is an exposed point or contact and a contact-box inclosing it.
D'is a contact-conductor, slightly longer thanthe intervals between the exposed points. Itis suspended from a traveling vehicle by insulators H and is lconnected to one terminal of the propelling-motor ot the vehicle. At each junction-box provision is made for establishing a connection between the exposed point in the box and the eontact-con ductcr D as the vehicle moves along.
In Fig. l F is a-leverpivoted at L and carry ing at its lower end a metallic contact-piece C, which is connected to the main conductor B by the flexible insulated wire G. The point O is insulated from the lever F by a bushing M.
A represents the walls ofV the box which extends through the paving, iiush with the street-surface, and connects with a drainage pit or pits R located below the pavement,
On the top of the box is an opening adapted to receive the socket N at t-he end of the lever F.
lll( is a trip extending horizontally through an opening in an oiset of the box where itis readily accessible from the surface of the street. The inner end of this pin bears against the shorter arm of ylever F and when forced in throws the lever up intothe position shown by the dotted lines. In this position of lever F the contact-pin O is raised above the surface of the roadway through the openings in the junctioirboxes, where it may come into contact with D and be held ,against it by the resiliency of the spring forming the longer arm of lever F.
E is a circuit-controller, carried by the vehicle and corresponds in length with conductor D, from which it is insulated. dThis circuit-controller is carried by the vehicle in such a position that it will strike the outer end of trip Il and forcing it inward throw the pin C against the conductor D. By this means an electric connection is established between the inclosed conductor B and the motor of the vehicle.
The conductor D is of such a length that it will -be in contact with two successive pins O at the same time, so that the connection between the motor and the supply-conductor is constantly maintained. The other terminal of the motor may be connected with asimilar apparatus, so as to be in connection with a corresponding supply-conductor, or the return-circuit may be through the rails or the metallic inclosnre of conductor B.
In Fig. 2 the conductor D is shown dia grammatically in contact with two points O. W'hen in its normal position, as shown in Fig.` l, the contact-point O is out of the path of travel of the contact device and in a position. inaccessible thereto. It is also ont of line with the opening in the top of the box, and any water or other substance which may enter said opening falls into the pit R, where it may be taken out at will without having caused any leakage or other trouble with the electrical arrangements. It desired, a cover may be provided for this opening, which will be operated by the circuit-controller E simultaneously with the trip H', This is shown IOO in Figs. 4 and 5, in which O is a sliding cover which takes the place ot the trip H. It is operated by a projection Q, which extends into the path of circuit-controller E. In passing around a curve the length of the circuitcontroller and contactconductor makes it necessary that the boxes be placed nearer together and in a curve which is eccentric to lthe curve of the track, as is shown in Fig. 3.
It will be 'seen from this figure that the circuit-controller is firmly held in an operative position by the springs S, which constantly tend to draw it to one side of the vehicle, so that the T-shaped points Pniay rest in corresponding sockets K. In rounding a curve the circuit-controller will take the position shown in dotted lines, while the trips ll or the offsets Q will have their corners rounded to meet the controller.
The means for connecting the contactdevice and circuit-controller to the vehicle are more clearly shown in Figs. 6 and 7. They are attached to opposite sides ot' an insulating block or blocks H, from which there extends upwardly the arm 7L, provided with an angle portion h', which rests uipon and is free to slide along the strap T, attached to a suitable portion U ofthe car structure. A spring s, connected at its respective ends to a bracket t and the arm 7L, normally-holds the contact device and controller in the position shown in Fig. 3.
