Title: Improvements relating to the dynamo-electric braking of electrically propelled railway vehicles
IPC: B60L7/22
Filed: 1954-08-24
Abstract: 751,925. Control of D.C. motors. KINGS MILL, H. L. Aug. 24, 1954 [Sept. 11, 1953]. No. 24570/54. Drawings to Specification. Class 38(3) Relates to a system of combined regenerative and rheostatic braking for traction motors with series-parallel control, the range of speed and braking-effort obtained during series regeneration being extended to include the range normally covered by parallel regeneration by the inclusion of substantially the whole of the starting resistance in series with the motor armatures. After the motors have been initially' connected in series for regenerative operation, the field strength is automatically increased and then the series resistance is gradually removed as the speed is decreased, whereupon a transition to rheostatic braking is effected, the fields of the motors being deenergied before rheostatic braking connections are established and re-energized as soon as these connections have been made. Maximum field strength is maintained during removal of the rheostatic braking resistance, which is controlled by sequentially-actuated contactors, until only one section of resistance remains in circuit with each motor for a period whereupon this section is removed and the fields of the motors are weakened. When the motors are initially arranged for regeneration and the voltage' developed by the motors does not reach a sufficient value in a given time interval. the line connections are not completed and the rheostatic braking circuits are established. The time interval referred to may be measured bv the rate of growth of field current acting on a relay. An over-voltage relay interrupts the field circuits of the motors and makes the rheostatic braking connections when there is an over voltage during regenerative operation. The speeds of the motors are regulated during braking operation by means of a current limit relay which controls the rate of increase of field strength and removal of series resistance, and this relay may have a bias coil which is excited in different directions' and in different degrees according to the position of a brake controller whereby the permissible braking current is altered on different notches of the controller. Alternatively, the contacts of the current limit relay may be supplied from a contact on the brake controller which can be opened when it is desired to reduce the rate of deceleration. A constant voltage exciter may be provided for the motor field windings, the field strength being varied by means of a series resistance controlled by sequentially-actuated contactors.

[Also in Division H1] A valve actuator comprises a worm (31) mounted on shaft 30 coupled to the output of a gear-box having a clutch which determines whether an electric motor or a hand wheel is effective to drive shaft 30. The latter is carried in slidable bearings 33 and supports a non- rotary slider 62 on bearing 76. Belleville springs 106 resist axial movement in either direction of slider 62 and shaft 30 until the torque on the worm-wheel (32) is such as to cause axial movement of the worm (31) and shaft 30. A groove 112 in slider 62 receives the end of pin 114 (Fig. 4) so that axial movement of shaft 30 pivots crank arm 116 to rotate spindle 118 to rock arm 124 to actuate switch lever 132 to stop the motor. In Fig. 5, shaft 150 drives valve shaft 163<SP>1</SP> through screw 152 and nut 158. Excessive torque causes axial movement of shaft 150 and slider 166 against Belleville springs 198 or 204 and causes actuation of switch (209) as above.

The rods 18 are of a nickeltitanium alloy which, below a certain critical temperature, exhibits a low-strength monoclinic structure whereby spring 15 can extend the rods to an extent allowed by slots 22 and unseat the closure member 27. Above the critical temperature, the alloy changes to a cubic structure and the rods revert to their original length, thereby reseating the closure member against spring 15. An overtravel spring 26 allows the closure member to be unseated by excess pressure. In a first modification (Fig. 3, not shown), each rod can consist of three endwiseconnected lengths having different critical temperatures, and flange 13 is axially adjustable to determine which lengths are to be effective. In another modification (Fig. 2, not shown), two concentric sets of rods are disposed in series to increase travel of the valve stem.
