Abstract: 290,152. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Young, H. S.). May 7, 1927, [Convention date]. Electric operation and control.-Controlling apparatus for electric motors operating railway points and crossings are connected to the motors through unidirectional conducting devices arranged as described in Specification 278,667, [Class 38 (iii), Electric motor control systems &c.], to take the place of local reversing switches. In the arrangement for controlling a direct-current reversible motor M operating points A, as shown in the Figure, the pointsman's controller consists of a group of electric contacts NB mounted on a shaft having a handle L, and an additional contact 29 operated by a lost-motion cam 24 on the same shaft. The main controller contacts, when the handle is moved from the position N to the position R, make reversing connections for the motor through a two-way switch 5 and four unidirectors 6 - - 9 arranged as shown with respect to the motor-field and the armature M. The auxiliary contact 29 energizes a locking and unlocking magnet 21, provided that the position of the points A correspond to that of the handle L. Free movement of the handle between intermediate positions B, D is allowed in order that the points may be given partial backward and forward movement when required to clear obstructions. The arrangement is provided with a circuit-breaker G arranged to open automatically if a cross connection or short-circuit arises on one of the lines 10, 11. A track-signal controlled by the relay K may be used to give indication of the fault. In a modified arrangement the controller and the unidirectors are, connected to a wound-armature. electromagnet which actuates switches for connecting the points-motor to a local source of current. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a motor having two field-windings respectively in series with two unidirectors, which may use half-waves of an alternating current supply. This subject-matter does not appear in the Specification as accepted.

Patent GB-361204-A (GB)
Title: Improvements in or relating to steering gear
IPC: B62D3/06
Filed: 1931-02-06
Abstract: 361,204. Motor vehicle steering- gear. DOUGLAS, J. G., Lansbury, Avenue Road, Leagrave, Luton. Feb. 6, 1931, No. 3824. [Class 79 (v).] Comprises screw - andnut steering-gear in which the translative movement of the nut is applied to .the arcuately-moving part of a rocker arm, characterized by the nut being adapted to rotate about its own axis during its movement of translation to compensate for the arcuate travel of the rocker arm. Thus, with a constant speed of rotation of the screw the rocker arm has an accelerated or decelerated movement as compared with the normal screw-and-nut gear. In the construction shown the steering-shaft carries a screw 1 engaged by a nut 7 free to slide and rotate in a fixed casing 3, the nut being formed with a radial bore 8 engaged by a ball 10 fixed to the rocker arm 12 mounted on a shaft 13. The drop arm 14, fixed to the shaft 13, steers the road wheels in the usual manner. As the screw rotates the nut travels along the screw, but its connection with the ball 10 also causes it to rotate about the axis of the screw. The casing 3 is provided with an arcuate slot 16 through which the ball 10 is passed. The midposition of the rocker arm 12 may be arranged to be at right-angles to. the axis of the screw as shown, so that rotation of the nut takes place on both sides of this position, or the mid-position may be arranged to occur when the arm is inclined to the screw so that no appreciable rotation of the nut takes place on one side of the mid-position. In the latter case the radial directions of the rocker arm 12 and drop arm 14 would not be parallel. The lower end of the screw 1 may be centred by a projection formed on a cover-plate 5 of the casing 3. In order to avoid back-lash the nut 7 may be split or slotted as shown at 18, 19 in Figs. 5 and 6, the split edges being drawn together by a screw 23. The screw 23 is turned to adjust the nut 7 by a tool 25 which can be inserted through an aperture in a boss or bosses 29 formed on the casing 3.
