Filed: 1922-02-11
Abstract: 197,406. Gill, J. F., and Chaviara, J. N. Feb. 11, 1922. Electromagnetic clutches; homopolar machines. -In an electromechanical power-transmission apparatus comprising a homopolar generator and a homopolar motor one or more of the elements which carry both flux and current are constructed of intersecting steel and copper portions. In the construction shown :in Fig. 1, in which two double C-shaped electromagnets a of cast steel are mounted on separate shafts b, the outer part d of each magnet is formed with teeth which pass through holes in a copper ring c<1>, and a stationary steel ring g in each machine is formed with holes through which pass portions of a copper cylinder e. The outer portions e<2> of the cylinder e and the outer surfaces of the rings c<1> are continuous. An outer copper element L is provided to complete the current circuit and is mechanically connected with, but insulated from, the cylinder e. Each magnet is provided with an annular polepiece l held in position by bolts m and around its outer periphery each pole-piece is formed with slots l<1> to diminish armature reaction. The magnets are excited by stationary windings n. Electrical connection between the stationary and rotating copper conductors is obtained by means of mercury or an amalgam of mercury and other metal. Rings t are provided for retaining the mercury near the spaces s when the machine is stationary. The parts in contact with the mercury may be nickel plated. The machines may be cooled by means of a fan u and water-jackets w. In another construction, one or more generators are made smaller than the motor, and are eccentrically positioned in relation thereto. The rotor 13 of the motor, Fig. 15, consists of a copper ring cast on to a radially slotted steel ring 10. The peripheral portions 11, 12 of the copper ring form the outer and moving parts of the mercury collectors 7, S. The magnet y is excited by a winding 4 and comprises a radially slotted steel ring with which are incorporated copper conductors 3 and a second radially slotted ring 6 having a solid face 28. The generator construction is the same as that shown in Fig. 1. A regulator for regulating the current in the generator and motor field windings so as to vary the speed, torque or direction of motion comprises a wire resistance coil 28, Fig. 18, wound on a drum 27 so as to subtend at the centre an angle of 90‹ and connected at its ends to copper quadrants 29, and four equally spaced contact brushes 31 connected in pairs to the field windings 32, 33. The resistance wire is of graded section and decreases in thickness from the outer to the inner turns.

[Class 38 (v).] A tilting mercury tube carried in a rocking- member operated by a solenoid having a gravity return, has the current leads from the tube connected to terminals which are also mounted on the rocking-member. A mercury tube switch 7 is fastened by clips 5a, 5b, to a channel-shaped rocking- member 5 pivoted on a pin 4. The core 15 of a solenoid 14 is connected by a fibre link 20 to the rocking-member 5. On the other end of the core 15 is a felt washer 22 which serves to damp the action of the core as it falls to its lowest position. Leads 10, 11 from the mercury switch 7 are brought out to insulated terminals on the carrier 5 so as to prevent constant flexure of the leads. In Fig. 1, the circuit is arranged for use on a flashing sign and one of the leads from the mercury switch passes through the solenoid 14. Thus, on switching on the solenoid is raised, the tube 7 is tilted and the circuit is broken. The core 15 then falls and the operations are repeated. A member 16 working between stops 17, 18 serves to limit the movement of the mercury switch.
