Title: Improvements in means for timing the accessories of internal-combustion engines
IPC: F02P17/04
Filed: 1939-11-14
Abstract: 538,789. Tuning valve gear and injection of I.C. engines. BRISTOL AEROPLANE CO., Ltd., and WILLIAMS, T. M. Nov. 14, 1939, No. 30072. [Class 122 (iii)) The movements of the piston and crankshaft of engines or pumps are correlated to some events associated with the operation thereof such as the timing of the valve gear or the injection timing of an I.C. engine. For this purpose the instrument comprises a member such as a rod 18 moved by the piston. This rotates on a displacement indicator comprising two parts 26, 27, movable relatively to one another to a limiting position of relative movement which is reached before the piston reaches the dead-centre position. Mechanism is provided for moving the two parts jointly by further movement of the piston towards the dead centre position when the indicator is locked against joint return movement whilst permitting relative return movement when this piston recedes from the dead-centre positions. Then as the piston moves towards its dead-centre position the two parts 26, 27 move first towards a zero setting. This setting is maintained until the piston reaches the dead-centre position and the indicator is held in this position by the locking means so that displacements of the piston are accurately indicated by the indicator in relation to the dead-centre position. The instrument provides a scale 33 and a pointer 39 both of which are pivoted to a movable carriage mounted on a hub 28 so as to be rotated in opposite directions by the movement of the piston. This arrangement magnifies the relative movement of the scale and pointer for a given piston displacement and a further magnification is obtained particularly for readings near the dead-centre position by cammechanisms between the piston-driven member and the indicator parts. The manner in which the instrument may be employed to check value timing of an internal combuston engine as well as the fuel injections timing is described.

Title: Vehicle seat
IPC: B60N2/50
Filed: 1973-06-25
Abstract: 1428714 Resiliently mounted seats BREMSHEY AG 25 June 1973 [8 July 1972 1 June 1973] 30111/73 Heading A4U [Also in Division F2] A vehicle seat support 7, Fig. 2, is supported on a compression spring 12 and is connected to a base 11 by pivoted cross links, an internally threaded collar 26 located on the spring being engaged by a threaded spindle depending from the support 7 and rotated by a reversible mechanism to vary the preloading of the spring. The seat is lockable in adjusted position along guide rails 5 on the support 7, Fig. 1 (not shown). The mechanism is a ratchet mechanism and includes a spring-loaded reversible tooth 35 engaging a ratchet wheel 34 which rotates the threaded spindle through gears 30, 32, the tooth 35 being carried by an operating lever 38 pivoted about the axis 33 of the wheel 34 and having a knob 41 connected by a rod 36 to the tooth 35 and the rod having a transverse pin 42 for reversible engagement in a slot 43 in dependence on which way the ratchet is to operate. Rubber pads 55 on the base 11 provide stops for the support 7. In a second embodiment, Figs. 5 and 6 (not shown), a damper extends between the support 7 and the base 11. In a third embodiment, Fig. 8, the mechanism includes an operating lever 73 pivoted about an axis 72 and carrying a plate 75 providing alternatively useable flanks 76, 77 for engaging the gear 32 directly. A reversing member 79 extends through a slot 78 in the plate 75 and lever 73 and it has an abutment member 80 providing a stop for engaging the end of an arm 71 pivoted on the axis 33 of the wheel 32. With the member 79 in the position shown movement of the lever 73 in the direction M1 will cause flank 77 to engage the wheel 32 to rotate it. Subsequent engagement of the member 80 with the arm 71 then also rotates the arm about the axis 33. Return movement of the lever 73 does not rotate the wheel 32 due to the relative disposition of the axes 72, 33 and the member 80. The mechanism is set for reverse operation by movement of the member 80 to the opposite end of the slot 78, Fig. 10 (not shown), whereupon the flank 76 engages the wheel 32. The flanks 76, 77 may engage a disc instead of the wheel 32. In a fourth embodiment, Fig. 12, the mechanism includes a spring-loaded toothed pawl 84 for reversibly engaging the wheel 32, the pawl being pivoted at 83 and connected by a rod 92 to a reversing slide 93 mounted in the operating lever handle 95.
