Title: Method and apparatus for removing camber from a metallic belt and/or for an endless belt from cold rolled metal strip
IPC: B21D1/02
Filed: 1952-09-09
Abstract: 735,579. Making belts. UNITED STATES STEEL CORPORATION. Sept. 9, 1952, [Feb. 13, 1952], No. 22595/52. Classes 83 (2) and 83 (4). Expanding and stretching.-A method of making an endless belt from cold-rolled metal strip comprises fastening the ends of the strip together and passing the belt so formed around a pair of spaced apart aligned automatic centring rolls arranged in parallel, applying tension to said belt, rotating one of said rolls to move the belt around the rolls and continuing the rotation until the belt is centred on the rolls so that any camber in the belt is removed. One of the self-centring rolls 2 is mounted in bearings 4 and 6 the bearing 4 being mounted on a platform 8 which is mounted on a base 14 having an arcuate guideway 16 which co-operates with a flange (not shown) on the platform 8. The position of the platform on the base is adjusted by means of a screw 22. The bearing 6 is pivotally mounted at 26 on a base 24. The roll 2 is driven from an electric motor 10 through gear-box 12. The second self-centring roll 28 is carried in bearings 30 mounted on a platform 32 slidable in a guide 34 in a base 36. The platform has tapered sides 38 which co-operate with wedges 40 mounted in the guide 34. A screw 42 operates the wedges to vary the distance between the rolls. The length of the rolls should be twice the width of the strip. In operation the ends of a length of cambered strip are fastened together to form a belt S which is placed around the rolls and tensioned by means of the wedges 40. When the belt is rotated by means of the motor 10 the belts will move laterally over the rolls such that the long edge of the belt will approach one end of the rolls and the short edge the transverse centre line of the rolls. As rotation continues the fibres adjacent the short edge of the strip are progressively elongated at a greater rate than the fibres adjacent the long edge and as the elongation of the short edge continues the belt S will move back towards the transverse centre-line of the rolls and the belt will then have straight parallel edges. When the strip is badly cambered the roll 2 is moved out of its parallel relationship with roll 28 to prevent the belt from riding too far off-centre. As the camber is reduced the roll 2 is gradually moved back until it is parallel with the roll 28. In a modification for use with wide metal belts a roller leveller 44 is inserted between the self-centring rolls. In operation the rolls of the leveller may or may not be driven and the direction of rotation of the belt S<SP>1</SP> is periodically reversed to prevent the joint J from passing through the leveller. The repeated bending of the strip over the small rolls of the leveller rapidly stretches all fibres in the width of the strip until they are equal in length and removes all camber from the strip. Specifications 709,908, 717,671, [Group XXX], and 735,561, [Group XXX], are referred to.

Title: Improvements in or relating to vehicle suspensions
IPC: B60G17/048
Filed: 1954-08-04
Abstract: 756,716. Hydro-pneumatic springs; spring suspensions. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Aug. 4, 1954 [Aug. 10, 1953], No. 22665/54. Classes 108 (2) and 108 (3). A hydro-pneumatic spring for a vehicle wheel suspension comprises a piston 14 and a cylinder 12 having a pressure chamber 16, a pump 24, a reservoir 23 and an accumulator 18, and is characterized in that the cylinder 12 has an annular recess 20 working in conjunction with conduits 27 and 30 formed in the piston 14, conduit 27 being connected to the reservoir 23 and conduit 30 being connected to the pump 24, both conduits opening on to the piston surface at such a distance from each other relative to the recess 20 that in an equilibrium position of the piston both conduits are in communication with the recess 20 while in a deflected position of the piston only one conduit communicates with the recess and thereby restores the piston to its position of equilibrium. The recess 20 is constantly connected to the pressure chamber 16 by means of a conduit 33. A conduit 19 connects the chamber 16 to the accumulator 18 for flow of liquid which is damped by a perforated non-return valve or valves 26. The accumulator is shown as an air vessel but may be a spring-loaded piston and cylinder, or a vessel containing extensible walls, or a liquid filled vessel containing compressible balls. An annular recess 21 drains liquid leaking past the piston 14 and returns it to the reservoir. Movement of the piston into the cylinder is limited by a cushion 37. In a wheel suspension (Fig. 1, not shown), a swivel pin is pivoted to a chassis cross arm by upper and lower links and the piston and cylinder work under compression between the cross arm and the lower link.

Title: Improvements in or relating to throttle valves for engines particularly for use in connection with carburettors of internal combustion engines
IPC: F02M1/00
Filed: 1920-07-30
Abstract: 157,062. Richardson, E. E. Jan. 10, 1920, [Convention date]. Closure members.- A hand- or governorcontrolled throttle valve for engines, more particularly intended for internal-combustion engines, consists of a pair of hinged valvemembers a closing on one another, which are moved simultaneously in opposite directions by toothed racks 33, 34, Fig. 1, on a slide 25, to open a passage for the gases at first through the axis of the casing between the valve members, and afterwards through additional passages between the valve-members and the sides of the casing, as shown in broken lines in Fig. 3, when the lower ends b of the valve-members move away from curved seatings 39, 40. The two arms a, b are of unequal length, so that the valves are not balanced, and therefore always bear on the actuating mechanism without backlash. During the later part of the opening movement of the valve-members, supplementary air is admitted to the valve-casing through holes 47, 48, Fig. 3, in the end wall uncovered by plates 49, 50 on the valve-members. These holes 47, 48 may be of different sizes, and one or other of them may be closed by a screw plug. A screwstop 52, Fig. 1, is provided to limit the movement of the actuating slide 25 and prevent complete closure of the valve-members, if desired. The slide 25 and the pinions on the valve spindles are arranged outside the end wall of the valve casing, and are enclosed by a cover-plate which bears on springs which keep the valve-members against the opposite end wall of the casing. This cover, and a cover for the connection of the slide 25 to the governor, are secured by screws which may be sealed to prevent tampering with the adjustments. The valve casing is in two parts 1, 2, held together during assembly by light screws 5, Fig. 1, and clamped together between the carburettor and the engine structure by long bolts 8 passing through light flanges 9, 10. In a modification, the actuating rack passes between the two valve pinions.

Abstract: 696,061. Change-speed gearing. BUTTERWORTH, A. J. Dec. 6, 1950 [Sept. 6, 1949], No. 23019/49. Class 80 (ii). Control means for motor-vehicle change-speed gearing comprises two pedals 20, 21, each connected to the engine clutch 1 and each carrying a pawl 22 or 23 co-operating with ratchet teeth on opposite sides of a slidable gear-changing bar 19. Depression of pedal 20 (or 21) first disengages the clutch 1 and then slides the bar 19 to change the gear one step downwards (or upwards), the clutch 1 being re-engaged on the return movement of the pedal, at the end of which movement the pawl rests clear of the ratchet teeth on a fixed part 24. As shown, gears 8, loose on a shaft 4 in splined connection with the hub 2 of the driven member of the clutch 1, are in constant mesh with gears 14 fixed on a shaft 13 which is geared to or may constitute the output member, the shaft 4 being connected by a lever 18 to the bar 19 so that, as the latter is operated, shaft 4 is moved longitudinally to bring clutch teeth 6 thereon successively into engagement with teeth in the gears 8. The latter are spaced by rings 10 or ball thrust races recessed into the gears. An oil tube 17 extends into a bore in the shaft 4 sufficiently far as to feed oil thereto in all positions of the shaft.
