UNITED STATES EDWARD M. BENTLEY, OF NEW YORK, N. Y.
ELECTRIC RAI LWAY.
SPECIFICATION forming part of Letters Patent No. 389,279, dated September 11, 1888.
Application filed August-3, 1888. Serial No. 281,884. (No model.)
To all 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 NewYork, have invented certain new and useful Improvements in Electric Railways, of which the following is a specification.
My invention relates to electric railways; and it consists in certain newand useful features of construction in the slotted conduit containing one or more supply-conductors for a railway, and also in a new and useful form ofeontact device to extend into the slot of a conduit and connect with the supply conductor or conductors inclosed therein.
My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a transverse section of a conduit on the line 1 1, Fig. 2. Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1. Fig. 3 is a side elevation of my contact device with a transverse guide therefor in section. Fig. 4 is an end elevation of the said contact device. Fig. 5 is a side elevation of a contact device in which two insulated conductors are employed. Figs. 6 and 7 are enlarged details of the contact-piece. Fig. 8 is a transverse sec tion on the line 8 S of Fig. 3. Fig. 9 is a de tail view of the insulator.
The main feature of my new conduit consists in a yoke adapted to support the slot rails and form with them the main skeleton of the conduit, the yoke having on one or both of its upper ends an enlargement reaching to the surface of the road-bed and hollowed out to form an inclosure for the insulator. This box has a removable cover accessible from the surface of the roadway, and within it is supported one or more insulators, from which a rod extends beneath the slot rail into the conduit and carries at its extremity the main conduetor.
The contact device or plow whiehlhave devised is an improvement upon the plow of the general type shown in Patent No. 338,175, issued to \Valter H. Knight, March 16, 1886.
The two main features of the contact de vice are, first, that the conductor, extending into the conduit, forms in itself a main supportingshank, the insulation and the guard being attached to it independently of the main support from which the whole device is hung; second, that the contact-shoes pivoted to the lower end of the conducting-shank have a spring-hinge normally holding the shoes out at substantiallya right angle to the shank, so that when inserted in the conduit the shoe will bear down upon the upper edge of the main conductor instead of on the lower edge of the conductor with an upward springpressure, as is the case in the said patent. WVhile the contact-shoe is normally held out by the spring in a horizontal position, it can be turned in either direction against the force of the spring, so as to be folded up into the shank or bent down vertically into line with the shank. By this arrangement the plow can be readily inserted or withdrawn through the slot of the conduit at any point, the shoe folding up into the shank when the plow is inserted and bending down into line with the shank when the plow is withdrawn.
Referring, now, to the drawings, A and B represent two slot-irons of a conduit in the form of an obtuse angle-iron.
O is the yoke,adapted to be placed at intervals and support the slot-rails A and B. The two ends of yoke G are enlarged into box 1), which extends to the surface of the roadway, where they have removable covers E. In box 1) is a ring-insulator, F, supported in an eye, G. Through the center of F extends a rod, H, which hasa second bearing in a notch on the top of insulator I.
J is the main conductor, having a loop, K, behind, which fits over the bent end of rod H. The rod H, havinga slight lateral movement in the notch of insulator I, permits of com pensation for any expansion or contraction which may take place in conductor K by reason of variations in temperature.
L represents a sheet-iron bottom which fills out the conduit between successive yokes C.
It will be readily apprehended that by the construction described each insulator along the line will be easy of access from the street by the removal of cover E. Since the rod H,
carrying conductor J, extends from within box B beneath the slot iron A, the latter can also be readily removed without any interference with the conductor or the insulator.
Referring, now, to the contact device, M rep- M and bolted thereto.
Q is a guard adapted to embrace insulation P and be bolted or riveted thereto. At its upper end shank M is provided with transverse pins RYR, which engage with openings on a sliding head, S, adapted to move in hollow transverse guide T, bolted to the vehicle.
In Fig. 5, where two conductors are employed in the contact device, they are insulated' from each other and from the frame, while the whole device is suspended by a piece corresponding to the shank M of Fig. 3, this piece having a sliding head engaging with the guide and performing the same functions as does the traveler in the device previously described.
It will be readily seen that the device described may be readily inserted or withdrawn through the slot of the conduit, and when in place the contact-shoe will bear down upon the upper edge of the conductor J, as is shown in Fig. 1. \Vhen the plow is to be inserted, the shank is simply pushed through the slot, the contact-shoe automatically folding up, as shown in dotted lines in Fig. 7, into the fork of the shank. After passing through the slot, the shoe springs out until it strikes the conductor, as seen in Fig. 1. To withdraw the plow, it is simply pulled upward, when the shoes strike the under edge of the slot and are bent down, as shown in the full lines of Fig. 7, until they are in line with the shank and pass through the slot without difficulty. It will also be seen that as the main conductingshank M passes directly up to engage with the transverse guide T the current is to be taken oft from the guide, and the usual flexible connection now employed to connect with the plow as it moves from side to side may be dispensed with, which is a feature of much practical value.
