Title: Improvements in and relating to car couplings
IPC: B61G1/08
Filed: 1919-08-26
Abstract: 154,331. Vinograd, E., and Groten, M. N. Aug. 26,1919. Couplings, automatic; draw-gear tensioning and slackening agents.-In automatic couplings for railway vehicles of the kind in which a clevis linked to a draw-bar is manually-operated into a raised position and is released so as to pull into engagement with the draw-hook of the other car by the compression of the contacting buffers, means are provided for elevating and manipulating the clevis additionai. to the main operating-means for raising and lowering the clevis and the links connecting it with the supporting draw-hook. Each clevis 30 is pivotally connected to a draw-hook member 20 by links 39, the clevis having a finger 30<a> which maintains the coupling-element rigid when the link is lifted. An extension 37 of the clevis is connected by links 55, 56 with a rock-shaft 57 operated from the side of the car to manipulate the clevis as desired On rotating a crank arm at the end of a shaft 45, the links and clevis are lifted through chains 42 on a drum 44 and a link 40, a detent 16 engaging a stop 17 to hold the coupling-members in the raised position for the coupling operation. As the cars come together, the buffers 13 are forced inwardly, the spindle 14 engaging an adjustable stop 50 to disengage the end of the pivoted arm 48 from the detent 16. This releases the shaft 45, and the link 39 is allowed to drop so that the clevis engages the draw-hook 20 of the other car. The detent may be released manually by handles 52, 51 on the detent and lever arm 48 respectively. When engaged, the clevis is prevented from uncoupling by retracting the hook 20 and draw-bar 19 by means of an eccentric 22 operated through a shaft extending to a hand-wheel at the side of the car, springs 54 being tensioned through a cross-bar 26. On the end cill, wing members 53 are provided at each side of the hooks to prevent disengagement of the clevis members when the cars are rounding a curve. In a modified arrangement for tightening up the coupling- elements, the draw-bars from each end of the car are oppositely threaded and engage a central nut, which may be operated through gearing from the side of the car.

Filed: 1930-07-11
Abstract: 356,866. Springs. RINGFEDER, GES. and HELD, T., Schutzerstrasse, both in Uerdingen, Niederrhein, Germany. July 11, 1930, No. 21075. Drawings to Specification. [Class 108 (iii).] In springs subjected to bending, differences between the tensile and compressive skin stresses are obtained by using cross sections such that the distances of the outermost tensioned and compressed fibres respectively from the neutral axis lie between the ratios 1:1À3 and 1:1À7. Alternatively the spring is treated in such a manner that the part under tension is tougher than the part under compression, the distances of the outermost tensioned and compressed fibres from the neutral axis being approximately the same. In a third method the spring comprises two different materials joined by rolling, welding or the like along the neutral axis.

Title: Improvements in and relating to indicating instruments
IPC: G01G1/18
Filed: 1937-07-30
Abstract: 495,134. Indicating - apparatus ; weighing-apparatus. TOLEDO SCALE MANUFACTURING CO. July 30, 1937, No. 21131. Convention date, Aug. 22, 1936. [Class 143] [Also in Group XIX] In an indicating instrument, for example a weighing-apparatus wherein a pivoted pointeractuating member is operated through opposed spring elements, the spring elements are non- pivotally attached to the operating means and to the pointer-actuating member and are bodily movable with the pointer-actuating member about its pivot. As shown, the pointer-actuating member 30 carrying the pointer 6 is pivoted on a ball-bearing 26 supported by the base 2 and is provided with openings in which are located oppositely-wound spiral springs 38, 40. One end of each spring is secured within its opening and the other end is secured to a pin 44 or 52 carried by arms 22 upstanding from the scale beam 10. As the scale beam moves, the pins 44, 52 move about the fulcrum 12 and by pressing on the spiral springs move the pointer over a chart 8 about its pivot 26. Owing to the relative arrangements of the pins 44, 52 and the pivots 26, 12, an amplified movement is imparted to the pointer. By a rotary adjustment of the pins 44, 52 the tensions of the springs may be varied. Such variation may be utilized to cause the pointer to move further to one side than the other for a given over or under weight. The movements of the pointer are damped by a loose ball contained within a housing 60 on the pointer-actuating member 30. The housing may be filled with oil or mercury.

Title: Change-speed gear control mechanism
IPC: F16H51/02
Filed: 1945-08-18
Abstract: 610,327. Controlling change-speed gearing. BENDIX AVIATION CORPORATION. Aug. 18, 1945, No. 21144. Convention date, Sept. 11, 1944. [Class 80 (ii)] In power means for the control of motor vehicle transmission gearing and of the kind comprising a double-acting fluid pressure motor operated jointly by a manual selector valve and by the vehicle throttle, the power element of the motor is connected to the gear-change lever by a compressible yieldable means and is actuated in three distinct stages in both directions of movement. As shown, a motor vehicle two-speed axle 10, Fig. 1, has mounted thereon a fluid motor 12, operated by engine suction, whose piston 16, Fig. 2, is slidable on the gear change rod 18 and is connected thereto through springs 24, 26 acting on collars 30, 34 fixed thereon. Casing stops 38, 40 limit the piston travel. The chambers 70, 72 defined by the piston 16 can be alternatively connected to the engine intake manifold 64, Fig. 1, through a pipe 62, a check valve 66, a storage tank 65, a two-way valve 39 and one or other of two pipes 56, 58 respectively, the valve 39 being manually operable and serving also to vent the idle pipe 56 or 58. As shown in Fig. 2, high gear is engaged. To change to low, the valve 39 is operated to admit suction to the chamber 72 and draw the piston 16 to the right to compress the spring 26 solid. No further action takes place until the accelerator pedal 41, Fig. 1, is released to unload the gear teeth when the piston 16 moves further to abut the stop 40 and in so doing neutralizes the gears, which on synchronization are meshed in low by the compressed spring 26 asserting itself. The reverse change is similarly effected. Change from high to low can also be effected by full depression of the accelerator as follows. Two ignition interrupter switches in series are provided, one, 46, on the gear change rod 18 and the other, 44, operable on full depression of the accelerator 41, which, when both are closed, earth the ignition coil primary winding 81 and cut out the engine. In high gear, the loading ball 88 of the switch 46 engages a cutaway 90 on the rod 18 and allows the switch to close so that full depression of the accelerator 41, allowed by spring lost-motion 78, cuts out the engine and unloads the gear teeth.

Sensing head, Fig. 19.-Light sources 414 and optical systems 416, 418 having axes inclined at 45 degrees to document 124 have associated photodetectors 424, 430 for sensing the indicia and line designating marks respectively. The head is driven across the document by a motor 360 and chain 376, Fig. 23, and is returned by a spring. Detector circuit. Fig. 8.-The output of detector 424 triggers a monostable circuit 93 when the start bar of each indicia group is sensed, and astable multivibrator 94 produces a train of pulses to enable gate 95 and at the same time to provide a train of short sampling pulses from monostable circuit 94<SP>1</SP>. The output of gate 95 is integrated at 96 and fed to a trigger 97 which responds at a given level. After shaping at 97<SP>1</SP> the output is sampled at gate 98. Document feeding.-The document is placed on a bed 126, Fig. 23, and is aligned against a stop 128 and a side edge 130. The presence of the document is detected by a photodetector which energizes a solenoid 140 to retract the stop 128 and a solenoid 152 to actuate a clamp 132 to engage the document. The clamp 132 is mounted on a carriage 134 which is driven by a pin 314 on a chain 312 engaging a hook 316. The clamp is released when the carriage 134 reaches the left-hand position. As the carriage 134 moves, pins 178 on a programme bar obscure a photodetector 184 at preselected positions, and simultaneous detection of a line designating mark by detector 430, Fig. 19, causes interruption of the drive to carriage 134, and initiation of a scanning traverse by head 350. On detection of a carriage return or line feed code or on actuation of a limit switch by head 350, drive to carriage 134 is resumed either after or during return of head 350 to the starting position.
