Abstract: 1288849 Starting prime movers ROBERT BOSCH GmbH 19 Nov 1970 [21 Nov 1969] 54942/70 Heading H2H A arrangement for starting an internal combustion engine comprises a starter motor 10 having a series winding 12 and an auxiliary winding 13 connectible to a battery 16 via contacts of a relay 14, the armature shaft 17 of the starter motor having a slidable drive assembly 18 including a sleeve 19 and a pinion 23 adapted to mesh with a flywheel 36 of the engine, the sleeve and the pinion being coupled by a screw thread 20 and the drive assembly being displaceable on the shaft 17 by the relay armature 35, the arrangement being such that prior to the meshing of the pinion with the flywheel the motor windings produce a low torque in one sense whilst on meshing, the windings produce a relatively high torque in the opposite sense. On closing a starter switch 40 the winding 13 is energized via a contact 41 of the relay and the winding 12 is energized via a winding 38 of the relay, the windings being energized in opposite directions so that the torque produced is insufficient to rotate the motor armature 11. The energization of the winding 38 causes the armature 35 to move the drive assembly 18 towards the flywheel 36 via a lever 34. If the pinion 23 meshes with the flywheel 36, contacts 42 and a switch 15 are closed thereby energizing the windings 12, 13 in the same sense. This torque is transmitted to a toothed member 22 of a clutch 21 via the screw thread 20 and the sleeve 19. The toothed member 22 engages teeth 25 of the pinion to rotate the pinion until the motor starts whereupon the pinion rotates faster than the shaft 17 thereby disengaging the clutch 21. If the pinion and the flywheel do not initially mesh correctly, the sleeve 19 moves towards the pinion thereby rotating it via the screw thread 20 until correct alignment is achieved. If the pinion, on its initial movement, joins against the flywheel, the movement of the sleeve 19 forces the drive assembly 18 to rotate slightly so that on operating the starter switch 40 a second time, change in relative positions of the pinion and the flywheel ensure that the jamming does not reoccur.

Abstract: 1301264 Monorail systems SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 14 Jan 1970 [27 March 1969 14 Oct 1969] 1850/70 Heading B7L  A monorail railway system comprises a vehicle 1 suspended from a rail 4 by roller 3, said vehicle being driven by a rotating cylinder 5 extending in the direction of vehicle travel and which engages a roller 6 mounted on the vehicle about a horizontal axis, and which may be rotated about a vertical axis to vary the vehicle speed, the vehicle centre of gravity and the roller 6 being on opposite sides of a vertical plane through the rail so that the weight of the vehicle biases the roller against the cylinder. Rotation of roller 6 about the vertical axis is by means of a roller 7 bearing on a profiled rail 9. Additional contact pressure of the roller on the cylinder can be provided by a roller 11 bearing on a rail 10. At a switch over from rail 4 to rail 12 the roller 6 is driven by a belt 13. Rail 12 is profiled such that when roller 16 engages therewith the vehicle is lifted off rail 4. Roller 17 bearing on rail 18 biases the vehicle against the action of its weight so that there is sufficient contact pressure between roller 6 and belt 13 to drive the vehicle. In the embodiment of Fig. 4 the roller is biased towards the belt by a roller 21 acting through lever 23 and spring 26. When the vehicle switches to rail 31 a guide roller 29 is lifted off rail 4 through levers 23 and 15. The profile of rail 31 causes the vehicle to be lifted from the rail 4 and a roller 33 biases the vehicle such that roller 6 abuts belt 13. The system may be used to transport vehicle 101 of a cable railway through a station. The vehicles are normally clamped to a moving cable 104 and at the entrance to a station a wheel 103 engages a rail 102 moving roller 109 into engagement with a drive cylinder 108, whilst at the same time a roller 114 engages a profiled rail 115 moving the clamp arm 113 to position 113<SP>1</SP> thereby releasing the vehicle from the cable. The speed of the vehicle through the station is then moderated either in the manner illustrated or by varying the diameter of the cylinder 108 and by providing conical drive surfaces.

Filed: 1969-10-22
Abstract: 1326537 Four wheel drives HARRY FERGUSON RESEARCH Ltd 21 Oct 1970 [22 Oct 1969] 51665/69 Heading B7H In a vehicle transmission one member 18 of a drive transfer 17 is connected to its associated final drive 10 by way of an overrunning clutch 19 whereof the member 18 is overrun by its drive input 14 when the road wheels rotate at the same peripheral speed. Drive will be transmitted to the front wheels 12 either if the rear wheels 13 tend to spin or if the front wheels 12 tend to lock only when the vehicle travels in a given direction. The system is made reversible by a four-wheel drive transmission incorporating a controlled interaxle or centre differential gear 22, Fig. 2. Clockwise rotation of the shafts 15A, 15B, and 14 correspond to forward drive. Clutch 27 permits only clockwise overun of the sun gear 25 and clutch 19 permits only anticlockwise overrun of the shaft 14. Releasable coulping means 2i establishes a direct coupling between sprocket 18 and shaft 14 only during clockwise rotation, i.e. foreward drive. Thus controlled four-wheel-drive is obtained both in forward and reverse drive. The coupling means 28, Fig. 10, is constituted by a hexagonal opening 33 formed in the sprocket 18 into which extends pins 34 through mating radial holes in the shaft 14. Movement of the plunger 36 to the left against the spring 37 allows pins 34 to adopt a retracted position from their normally retained radially extended position, and allows the sprocket 18 to rotate freely with respect to the shaft 14. Springs (not shown) preferably bias the pins 34 towards their retracted position. Anticlockwise rotation of shaft 14 is transmitted to plate 41 through flange 38 and friction plates 39, 40 and plates 41, 42 are thrust apart by means of opposed ramped grooves (44), Fig. 13 (not shown) containing actuating balls 45. Brake 43 permits only clockwise rotation of plate 42 and plate 41 is axially shiftable. Thus plunger 36 is thrust leftwards. Limit pins (46) engaging slots (not shown) in plate 41 serve to limit anticlockwise rotation of the latter to prevent disarrangement of the balls 45. The plunger 36 may alternatively be actuate by a screw thread, a face cam, or by hydraulic pressure fluid being operated simultaneously with reverse gear. The interleaved friction plates 39, 40 may be replaced by a cone clutch or a single face plate clutch.
