Abstract: 834,387. Axle mountings for railway vehicles. HUNSLET AFRICA (PROPRIETARY) Ltd. June 16, 1958 [June 24, 1957], No. 19179/58. Class 103(6) [Also in Group XXXI] An arrangement for setting the axles and so tensioning the chains of a chain-driven locomotive comprises a cross-shaft connected to the boxes of each chain driven axle by a pair of cranks and connecting links whereby rotation of the cross-shaft causes lateral motion of the axles. As shown, a locomotive 1 has axles 2 and 3 driven from a gear box 4 via sprockets 5, 6, 8 and 9 and chains 7. A cross shaft 10, at 90 degrees to the length of the frame, is connected to the axle boxes 13 of each axle by cranks 12 attached to the ends of the shaft, and links 16. A lever 17 is attached to the shaft and to an adjusting screw 19. Limit stops 20 may be provided. To take up wear in the chains, the axle mountings are loosened and the screws 19 tightened until the desired tension is obtained whereupon the screws 19 are locked and the axle mountings are secured. The axles are mounted upon resilient rubber pads, or, in a modification, upon leaf springs, one end of each spring being connected to the respective crank upon the cross shaft while the other may slide in a suitable guide. Alternatively, each chain driven axle may have its axle boxes removably clamped to the leaf springs so that to adjust the chain the axle boxes must be loosened, set and reclamped along the lengths of the springs, the axle boxes being connected to the cranks upon the cross shaft. The cranks may be replaced by eccentrics and the cross shafts 10 may each carry a disc provided with a series of circumferential holes through any one of which and a hole in the frame a locking pin may be passed.

Abstract: 699,958. Windscreen cleaners. O'SHEI, W. E. Nov. 5, 1951 [Aug. 4, 1950; Sept. 5, 1950; Sept. 7, 1950], Nos. 19549/50, 21881/50 and 22074/50. Class 138 (i). A dual windscreen wiper unit comprises a frame carrying two wiper arm spindle bearings positioned at an angle to one another, the spindles in said bearings being driven from a common oscillable driving spindle carried by the frame between the wiper spindles, through a mechanical transmission connecting the driving spindle to the wiper arm spindles, wherein the portion of the frame to which at least one of the wiper spindle bearings is attached is connected to the remaining portion of the frame through a hinge or a flexible or easily bendable connection so that the angular inclination of that spindle bearing relative to the frame may be altered. The frame comprises a thin sheet metal bar 1 with central strengthening flanges 1a and end portions 3, 3a which are flexible or bendable so that the wiper spindle bearings 5, 5a and spindles 4, 4a may be adjusted angularly when mounting the unit in the vehicle. In a modification one or both portions 3, 3a may be separate from the central portion and connected thereto by a hinge formed by a length of flexible strip material. Alternatively the ends may be entirely of such strip material riveted or welded to the ends of the central portion. A motor 2 is supported centrally of the frame 1 and a crank 7 on its spindle 6 reciprocates a connecting rod 9, the bent ends 10, 10a of which connect with cranks 8, 8a on the wiper spindles. Since transverse twisting of the rod 9 must take place, as shown at 11, 12, in Fig. 2, when the rod reciprocates the connection between the rod and the pin of crank 7 is made sufficiently free to permit such twisting and thus prevent binding. In another modification the central portion of the rod 9 may move in guides and each of the ends 10, 10a are pivotally or flexibly connected to the central portion so as to pivot or flex about a substantially vertical axis when the rod reciprocates.

Abstract: 222,612. Britt, T. Aug. 1, 1923. Hand actuation; force-transmitting mechanism. -Brake mechanism for railway and road vehicles comprises a main rotatable member provided on both sides with helical cam faces co-operating with corresponding cam faces on a pair of cam members one or both of which are moved laterally to effect the application of the brakes upon rotation of the main cam member. Locking mechanism for the brakes which is adapted to be disengaged by movement of the hand lever to release the brakes is also described. Fig. 2 shows a main rotatable cam member A provided with three helical cam faces on each side, co-operating with a pair of laterally-movable cam members B, C provided with similar cam faces and connected by links or push-rods K to the brake blocks of a railway wagon. The cam faces are stepped as at F so that a relatively-quick initial movement is given to the cam member B, C to bring the brake blocks into engagement with the wheels. Returning springs G are disposed between the cam members B, C and a fixed frame member D in which these members are mounted. The cam member A is adapted to be turned by the usual side lever of the wagon by means of a link L<1> connected to the lever and to an arm on the member A. One form of locking mechanism comprises a pawl Q, Fig. 5, arranged to engage teeth P formed on the cam member A and controlled by the engagement of a pin Q<2> on the pawl with a slotted lever R pivoted on the cam-actuating arm L. The link L' from the hand lever is connected to the lever R and has also a lost-motion connection with the arm L so that the pawl is disengaged by the initial movement of the hand lever to release the brakes. With this arrangement, operation of the brakes from either side of the wagon can be effected. According to another form of locking mechanism, the hand lever T, Fig. 7, and an arm W are both secured to a shaft U upon which an arm V connected by the link L<1> to the cam member A is freely mounted. Projections W<1> on the arm W provide a lost-motion connection between this arm and the arm V whereby the pawl V<1> which engages teeth on the arm V is tripped during the release movement of the lever T by the engagement of a projection W<2> on the arm W with a member X pivoted upon the arm V. When it is desired to operate only a single pull-rod by the cam mechanism, as in the case of a brake for a motor road vehicle, one of the cam members B, C is fixed to the frame D and the pull-rod is arranged to pass through the three cam members and to bear by means of a nut upon the outer laterally-movable member.
