ELECTRIC RAILWAY.
$PECIZE'ICATION forming part of Letters Patent No. 338,174, dated March 16, 1886.
Application filed May 11, 1885.
To all whom it may concern:
Be it known that I, WALTER H. KNIGHT, a citizen of the United States, residing at Cleveland, Ohio, have invented certain new and useful Improvements in Electric Railways, of which the following is a specification.
My invention relates to devices for maintaining electrical connection between an electric locomotive and the electric conductors that extend along the line of the railway.
In the accompanying drawings, Figure 1 is aside view of the device. Fig. 2 is a section of a single plow. Fig. 3 is a side view of the device when thrown out of position. Figs. 4, 5, and 6 are details.
The general arrangement of my device is similar to that shown in my Patent No.305, 731, September 23, 1885, there being a slotted conduit inclosing the conductors and 2. depending carrier extending into the slot, to which is attached an insulated conductor terminating in a contact device adapted to slide along a conductor fixed to the wall of the conduit.
My invention is not limited to two fixed conductors in the slotted conduit, for the conduit itself or the track-rails, or both, may take the place of one conductor.
In Fig. 1, x y represent the line of the conduit-top, and A A are the depending carriers, or plows, as they are preferably termed.
E is a supporting-frame, hung from fixed parts 0 O of the locomotive by the pivots ee, about which as a longitudinal axis it is free to swing. To this frame E the plows are attached by means of rigid connections F F, which are pivoted to the frame so as to swing freely about a transverse axis, the two plows being connected together by pivoted connecting-bar G,
so as to havea parallel movement about the 'are beveled, so that when the plows meet an obstruction the lever is thrown out of the notch and the plows come up through the slot into the position shown in Fig. 3.
Each plow consists of the solid metallic 5o shank extending through the slot and taking the wear against the sides. To the lower end Serial No. 165,103. (No model.)
of this shank is hinged afoot, B, of insulating material, by means of spring-hinge D, and a metallic contact-shoe, O, is fastened on the shoe, so as to be pressed constantly against the main conductor by the said spring-hinge. Through the shank and the foot B is drilled a small hole, as shown in Fig. 2, (which is a section on line 2 2, Fig. 1,) and a small insulated conductor, L, is passed through it, and connected at its lower end to contact-shoe O and at its upper end to binding-post M, whence a flexible conductor leads to the motor on the locomotive in the usual manner. By this arrangement the motor is kept in constantcou nection with the mains as it advances, the two plows connecting with the twomains, respectively.
When the plow is thrown out, as shown in Fig. 3, it is desirable that the motor-circuit should be broken at the same time, and this is accomplished by placing a switch in the circuit, which is automatically operated by the movement of lever K in either direction from its vertical position.
In the drawings, S is an insulatingbase holding two contact-plates, s 8, connected to the two terminals of the motor-circuit. This base is fastened to frame E, so as to move with it, and the lever K, whenin its normal position, closes the circuit between the plates 8 s, but breaks the circuit when thrown over, as in Fig. 3.
It will be seen by reference to Fig. 2 that the insulating-foot B is larger than the contact-shoe O; and in Fig. 5 it is shown that the shoe is not of a sufficient length to bridge the space between the conductor and the edge of the slot, but that the foot is, so that the foot and shoe may be inserted or withdrawn from the conduit and no electrical connection be made between conductor and conduit, for the insulatingfoot will guide the shoe onto the face of the conductor, and the conductingshoe will not bridge across from slot to conductor. The foot B is preferably made of vulcanized fiber.
Several features of the plow above de scribed are shown but not claimed in an application filed herewith.
The following mattcrshown herein is reserved for claim in application Serial No.
165,102, of even date herewith: The combination,wit-h a railway and an electric locomotive thereon, of a stationary supply conductor parallel with the railway, and a contact-conductor resting constantly upon said supplyconductor and supported from the locomotive by a connecting device capable of lateral movement about a longitudinal axis.
