INSULATING-BLOCK FOR ELECTRIC CON DUCTORS SPECIFICATION forming part of Letters Patent N 0. 761,877,. dated June '7, 1904.
Application filed My 7, 1903. Serial No. 164,559. (No model.)
I 1'0 tall whom it mcty concern.-
' Be it known that I, CHARLES M. CLARK, a citizen of the United States, and a resident of .South Orange,.New Jersey, have invented certain new and useful Improvements in Insulating-Blocks for Electric Conductors, of which the following is a specification.
My invention relates to conductors for supplying currentto motors, and is intended primarily for telpherage systems.
It has for its immediate object to provide an insulation-block in the conductor, so that the -.motor will be automatically stopped at prede In the drawings forming part of this specification, Figure 2 is a view of the bottom of the insulation-block. Fig. 1 is a diagram showing the invention. Fig. 3 is a View, partly in perspective, showing the switch and connections to the motor.
A represents the line-wire, and B the insulation-block, and C the line-wire beyond the same.
D represents the telpher which travels along the track E, said track forming a part of the return-circuit with a ground-wire at F.
G and H represent wires conveying the current to and through the motors, and included.
in the circuit of these wires is a solenoid I. To the core of this solenoid is attached a lever or pawl J engaging with the ratchet K on the reversing-switch. This reversing-switch is of the common and well-known kind whereby rotation of the switch in one direction will reverse. the motor. As shown in the drawings, when the solenoid is energized the core rises against the force of the spring L, the pawl sliding over the ratchet-teeth. When the solenoid is deenergized, the spring L forces the core down and through the medium of the pawl J turns the switch, as will be readily observed. The switch is of an ordi- D the wire running from nary type and illustrated in Fig. 3, in which Z represents the disk having contact-pieces d i, in contact with which are the brushes 6 0 IL in. The ratchet-wheel is indicated by K and the shaft on which said wheel and disk are secured by K. The circuit through the motor is as followsi from the current-wireAthrough the trolley-pole a, wire 6, brush 0, contactpiece d, brush a, wire f, motor D, wire g,
brush 7t, contact-piece e', brush 70, wire a, to the track E, thus completing the circuit. The position of the contact-pieces and the cir-,
cuit through the motor when the switch is in I the other position will be readily observed. The line-wire C is connected by means of a wire M to the source of current-supply, and in this wire is the solenoid N, having a contact-pieceO, adapted to be engaged by the armature I. A branch wire Q runs from said wire M to said contact-piece O. The insulating-block B is formed of wood or any other suitable material, in which the ends of the wires A and U are embedded. On the bottom of said insulation-block and running the length thereof is a supplemental wire A, so placed that the trolley of the motor engages with both wires. Connected to this supplemental wire A is a wire B, the other end of which is in electrical connection with the armature P.
C- represents the usual resistance-box, and
thence to the conductor A. v
The operation of the device is as follows: Supposing the telpher to travel from left to right, looking at Fig. 1. Upon the trolley striking the insulation-block the current is cut off and the motor will reverse, as heretofore described. The inertia of the telpher will carry it along until the trolley makes contact with the Wire C, and the motor now acting as a brake will stop the car; but as the wire 0 is energized through the wire M the circuit.
through the motor is immediately established and the telpher starts to travel back. At the same time, as heretofore described, the core of the solenoid I will be drawn up in readiness to operate the switch, when the circuit is again broken. It is obvious that under these conditions the motor would be again reversed When the trolley struck the insulation-block; but it Will be noted that as the circuit is established through the motor and the return- Wires the solenoid N becomes energized, drawing up the armature P in contact with the contact-piece 0. Through the branch wire Q and wire B the wire A becomes energized, and as the motor travels along the trolley engages the wire A before it leaves the Wire C. Consequently as the trolley passes along the insulation-block the current is maintained through it, and as the trolley strikes the wire A before it leaves the wire A the current will be constantly maintained until the motor is stopped at some predetermined point.
