IPC: B61G1/08
Filed: 1920-07-07
Abstract: 160,397. Mackinnon, F. A., and Hampson, J. July 7, 1920. Couplings, automatic.-In an automatic coupling for railway and like vehicles wherein each vehicle is provided with a draw-bar with hook, a link and arrow headed hook member are pivoted to the same pin on the draw-bar so that on collision the link of one vehicle is guided into engagement with the hook of the draw-bar of the other vehicle whilst the link of the latter is simultaneously moved into a position to engage with one of the hooks on the pivoted hook member. On meeting, the link e of one vehicle strikes the inclined surface c' of the opposing hook c, slides up and raises both the tumbler hook F and link e, and drops behind the hook c. The tumbler hook F then falls and secures the link e and at the same time the raised link e falls over the surface f<2> of the tumbler hook F of the other vehicle enabling a double coupling to be effected. In uncoupling, the handle l of the transverse shaft secured to the vehicle a<1> is depressed, the lever k<2> tilts the cheek f<3> of the hook F and ejects the link e from engagement with the hook, the link e at the same instant being raised clear of the surface f<2> of the opposing tumbler hook. Means are provided to retain the handle l in the depressed position when necessary. The coupling may also be combined with central buffing gear.

Title: Improvements in or relating to pneumatically and similarly operated vehicle brakes
IPC: B60T13/36
Filed: 1929-06-24
Abstract: 314,305. Skoda Works, Plzen. June 23, 1928, [Convention date]. Fluid-pressure.-Control valve mechanism for fluid-pressure operated brakes is adapted to establish a pressure in a chamber 10 dependent upon the position of the operating member 7 of the control valve mechanism, while slide valves 9 simultaneously operated by the member 7 through lever 6 and rod 5 directly control communication between chambers 1, 2, 3 connected to the corresponding brake cylinders and the chamber 10. The pressure in the chamber 10 is determined by inlet and outlet valves 12, 17 loaded by springs 14, 18, the pressure of which on the valves can be adjusted by the control member 7 and sleeves 15, 19. The spring 14 acts in opposition to a closing spring 13. The chambers 1. 2, 3 are normally open to the atmosphere by slide valves 8. By operating the member 7 these valves are closed and the valves 9 are opened. At the same time the pressure of the valve springs 14, 18 is increased so that the valve 12 is opened and compressed air is admitted to the chamber 10 until the pressure therein corresponds to the reduced spring pressure acting on the operating member 7. The pressure in the chamber 10 may be gradually reduced in a similar manner by returning the member 7, the reduction of the pressure of the spring 18 permitting the exhaust valve 17 to open until a corresponding reduction of the air pressure in the chamber has been effected. The valves 8, 9 directly control the outflow and inflow of the pressure medium from and to the chambers 1, 2, 3.

Title: Improvements in and relating to variable speed transmission control mechanisms
IPC: F16H61/30
Filed: 1936-07-16
Abstract: 476,820. Controlling change - speed gearing; valves. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. July 16, 1936, No. 19741. Convention date, July 17, 1935. [Class 80 (ii)] [Also in Group XXIX] Fluid-pressure means for actuating a gear-shifting member 18 comprises a cross-shift motor 26, which, for selection amongst three gear-strikers 5, 6, 7, turns the member about the common rod 16 of gear-establishing pistons 14, 15, which thrust the member longitudinally in either direction, an additional pair of simultaneously energized pistons 77, 78 being provided, coaxial with the pistons 14, 15, for neutralizing. The neutralizing pistons 77, 78, abut loosely against the gear-establishing pistons 14, 15, and are of smaller area than the latter so that they are overridden during a gear-establishing operation. For cushioning the final gear-engagement, each neutralizing piston carries a conical needle 79, which progressively closes the air outlet 80 towards the end of the gear-establishing stroke. Supplementary one-way valves 83 may be provided for energizing the neutralizing pistons. The cross-shift motor 26 comprises a double-acting piston 27, biassed by springs 28 into a central position, so as to select the middle fork 6 when de-energized. On operation of a mainclutch pedal 55, controlling a cut-off valve 54, compressed air is supplied from a reservoir 56 to a motor 10 for disengaging the main-clutch at 9 ; to both neutralizing pistons 77, 78, and to the two valves 36, 38 of a manual selectorunit 8, which lead to the gear-establishing pistons 14, 15. The remaining two valves 37, 39 of the selector-unit 8, lead to opposite sides of the cross-shift motor 26 and are directly energized from the reservoir 56, so that, although energization of the gear-establishing and neutralizing motors must await disengagement of the main-clutch, the crossshift motor can be energized at any time. The selector-valves 36.. 39 are operated through cam-mechanism, not described, by a universally-mounted gate-guided lever 40. The valves themselves are self-lapping and each include a piston 61, Fig. 3, operated through a spring 68 by the cam-follower 46, and serving, when depressed, to seat an exhaustvalve 69, cutting off communication between atmosphere above the piston, and a lower outlet-chamber 63 leading to the appropriate gear-controlling motor. Further depression of the piston opens a spring-loaded inlet-valve 70, integral with the exhaust valve and controlling a pressure-inlet 71. Pressure thus supplied to the outlet-chamber 63 acts under the piston to lap the inlet-valve 70, necessitating further pressure to be exerted by the operator for the inlet-valve to re-open. Preselection from neutral is possible, and the clutch-control valve 54 is of the progressive type described in Specification 471,999.

Title: Improvements in or relating to knitting machines and methods of knitting
IPC: D04B9/26
Filed: 1931-07-09
Abstract: 381,599. Knitting-machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H.; 55, Cooke Street, Pawtucket, and Cloutier, A. N.; 495, Broad Street, Lonsdale, both in Rhode Island, U.S.A.) July 9, 1931, No. 19752. Convention date, Aug. 13, 1930. [Class 74 (ii).] In machines for the production of plated work at times, and of plain, i.e. unplated work at other times, the yarns are laid or passed over or to the back of the sinker nibs 40 so as not to be caught by them, e.g. during reciprocation, by advancing the sinker cap as described below, or otherwise. The plating loops are drawn out so as effectually to cover the ground yarn, which is under substantial tension. The plating guide is placed out of action, prior to knitting plain courses, by a vertical sliding movement. During the last complete circular course preceding the knitting of the heel a cam-controlled abutment lever 21 is lowered and this permits the sinker cap 4 to move forward until arrested by the impact of the adjusting screw 32 against the yarn lever box 30, Fig. 8 (not shown). The sinkers are thus advanced earlier than would otherwise be the case, and their nibs 40 pass beneath the heel and toe yarn, in the same way as, during reverse plating, they pass beneath the ground and plating yarns. During the reverse strokes, the sinkers are advanced by a cam 94. The heel and toe yarn is also kept clear of the sinkers companion to the instep needles during reciprocating. Scissor action of the latches on the plating yarn is reduced or avoided by making the inner edges 104 concave. The adjacent faces of latch and needle shank are inclined at an angle of 22‹ when the latches are closed. A relatively short latch is used. Specifications 20101/09 [Class 74 (ii), Knitting &c.], and 357,314 are referred to.
