JOHN J. SAVIliLl AND JAMES H. \VINSPEAR, OF OMAHA, NEBRASKA.
ELECTRIC CONDUCTOR.
SPECIFICATION forming part of Letters Patent No. 417,095, dated December 10, 1889.
Application filed March 11, 1889.
To aZZ whom it may concern.-
Be it known that we, JOHN J SAVILLE and JAMES H. WINsPEAR, citizens of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have jointly invented a new and useful improvement in conductors for conveying electric currents from a dynamo to street or railway cars for motor purposes, of which the following is a specification.
Our invention relates to a system of appliances by which electric force is taken from an underground insulated conductor, entirely covered and embedded in insulating material, from points at various distances apart, and conveyed to an electric motor upon a street or railway car. Said appliances and conductors may be placed and operated wholly or in part above orbelow ground. We attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of our device attached to the trucks of a motor-car and in position for operation. Fig. 2 is a plan view of the carrier-frame and carrierbar in place upon car-trucks. Fig. is a transverse sectional view of our device on line 1 2, in position and in proper relation. Figs. 4 and 5 show power-wire F and lateral wire q with insulating material removed and a section of power-wire and lateral wire; Fig. U, enlarged view of hinge or joint of carrierbar; Fig. 7, enlarged view of clamp. Fig. 8 is a sectional elevation of the transmitter. Fig. 9 is a plan of the transmitter. Fig. 10 is a section of the transmitter on the line a. Fig. 11 is a section of the transmitter on line 5 (3. Fig. 12 is a perspective view of rubber seat and casing Z. Fig. 13 is a perspective view of journal-box '1.
In Fig. 1, A is an iron frame, which rests upon and is attached to the axles of the cartruck inward from the wheels by boxes to a. I) b are arms extending down from frame A and united by a cross-bar, (not represented in this view, but represented and marked 0 in Fig. 3,) which serves to support the can rier-bar B, and is thus placed in order to avoid the motor machinery, which is placed about the truck-axles. It is obvious that the construction of this frame may be varied to meet the requirements of differently-con- $erial No. 302,900. No model.)
stucted motors. The carrier-bar B is iron and in three sections, united by hinges or joints 6 c, which are so constructed as to permit the end section to move vertically and laterally to accommodate the carrier to the curves and grades of the track. (See Fig. 6.) The middle section is attached to the cross-bars c c, Fig. 3, by a box (Z d, which permits a slight sliding lateral motion to accommodate the carrier to the side motion of the trucks from any unequal distance of the rails from the center line of the track. The arms ff are attached to the middle section of the carrier-bar B and terminate in a clamp 9, (see Fig. 7,) to hold and carry the conducting-wire G. The arms f f are similar to f fin all respects, except that they are attached to the end sections of the carrierbar B by a bolt, which permits a slight backward and forward motion of the arm to prevent strain upon the conducting-wire when passing around curves. The guide -wheels 7L hare attached to the arms f f to keep the conducting-wire in constant proper relation to the transmitter E. The guards 2' i are attached to the ends of the carrier-bar B by a round belt, which permits a lateral mot-ion to accommodate it to curves, but does not permit a backward or forward motion. It is slightly curved and grooved to receive the conducting-wire, and serves to protect the wire from injury. It also serves as a fixed point for the spring 7.1, which draws the arms f f" forward, holding the conducting-wire taut. The insulating material is removed from the conducting-wire C. of zinc or other metal, soldered to the conducting-wire C and covered with vulcanite or other insulating material, and are constructed with a bead at the upper edge to fit the clamp g, Fig. 7; The rod m m, with a sliding head n, passes through a hole in the carrier-bar B, serves to hold in place the spring 0, which presses down the carl'ienbar, and keeps the gnidewheels h in place on its track. p is a slot or opening into the conduit D, through which the arms fff f and guardsi '0' pass to carry the conducting-wire C along the conduit. The guide-wheel h runs upon the bars which form this slot, thus guiding the conducting-wire O and holding it'at the proper height to form a contact with the transmitter Z Z Z Z are plates,

E. In the box G the power-wire F is placed for protection from moisture and other inj urious influences. Itis broken to show the power-wire F where it is attached to the trans- The power-wire F is placed in any convenient position relative to the transmitter to permit the lateral wire g, which is attached to and is a part of the power-wire F, to enter an opening in the side of the case-box K (see Figs. 8, 9, and 10) to connect with the transmitter, as shown in detail in Fig. 8. The power-wire F and the lateral wire 1 are 011- tirely covered and protected by proper insulating material except at point of contact in the transmitter, as shown in Fig. 8.
In plan view, Fig. 2, the carrier-frame is shown resting upon and attached to the truck-axles by boxes a a a a. c is the crossbar connecting the arms 1), extending down from frame A, and supports the carrier-bar 15, which is attached to c by the sliding box (1, permitting a slight lateral motion, as described above. The axle is broken to show the cross-bar c beneath. e e are the hinges or joints of the carrier-bar B.
n is the sliding head of the rod on, Fig. 3; f f, arms of carrier-bar, and h guide-wheel.
In Fig. 3, n is the sliding head to rod 111. It consists of an iron frame having three antifriction wheels 0 r r, is placed upon the end bars of the carrier-frameA, and has a lateral motion, carrying the rod m and spring 0, to keep them in position relative to the carrierbar B as it moves from side to side in curves of the track. The purpose of this attachment as a wholeis to press the carrier-bar 13 down, so as to keep the guide-wheel h in position on its track. E is the transmitter, suitably located or positioned to hav'e contact with the conducting-wire O. F is the insulated wire having a lateral wire-connection q with the transmitter E.
In Fig. 8, II is a compound wheel composed of a copper wheel 5 and axle on one side 5', which isinsulatcd by rubber or other insulating material 6 6 from the iron casings u 11, which are firmly riveted together, the rivets also being insulated from the copper. This wheel is mounted in an iron frame I by means of sliding journal-boxes r n, resting on the spiral spring 10 U. The frame I is held in a casing-box K by grooved recesses 50 in the side of the box. On a bench y on the side of the frame I is a rubber seat and casing .2, upon which rests the end of the lateral wire q. The end of the wire (1 is grooved to fit the copper axle s, and the rubber seat and casing z surrounds the wire q and the axle s',thu s entirely insulating them and protecting them from all external objects. L is a glass cap over the compound wheel H, to protect it and to form an insulating-guide to insure contact of the conducting-wire C with the copper wheel 5 of the transmitter. The glass top is bolted to the top of the casingbox K.
The action of the transmitter is as follows: The conducting-wire C, passing over and pressing on the wheel II, forces the axle 8 down upon the lateral wire (1, thus forming continuous electrical connection from the power-wire F through the lateral wire q, the copper axle s, the copper wheel 5, and the conducting-wire C, to the motor on the car. As soon as the pressure of the conductingwire C is removed, the spring 10 to acting upon the sliding journal-boxes "r, raises the axle s from the lateral wire q, thus entirely breaking electrical connection between the power-wire and external objects.
The usefulness of our invention consists of the use of a conductor entirely covered by and embedded in insulating water-proof material, whereby it may be placed under ground and thereby protected from accidental contact with persons and animals, whose lives might be thus endangered; also, whereby the loss of electric force may be prevented from leakage, or from water, ice, vapor, or other conductors coming in contact with it; also, by action of the transmitter a constant electric current is carried to the motor, the wheel of the transmitter preventing friction and sparking as the conducting-wire comes in contact with it.
\Vhat we claim, and desire to secure by Letters Patent, is
1. The combination of the transmitter E, the power-wire F, lateral wire q, covered and embedded in insulating water-proof material, the frame carried by the car-truck and having pendent arms connected by cross-bars, the carrier-bar formed of sections, having lateral and vertical. movement arms depending from said carrier-bar and having clamps, and the conductor-wire, substantially as set forth.
