Title: Improvements in or relating to Automatic Centrifugal Clutches.
IPC: F16D45/00
Filed: 1967-10-25
Abstract: 1,166,337. Friction clutches; ratchet clutches; clutch control. HONDA GIKEN KOGYO K.K. 25 Oct., 1967 [26 Oct., 1966], No. 48597/67. Headings F2C and F2L. In a centrifugally engaged friction clutch of a motor vehicle, wherein inner and outer friction clutch discs 11, 12 between an engine shaft 1 and an output gear 4 are automatically engaged by the centrifugal action of rollers 21 rotating with the engine shaft, the inner discs 11 are connected to the gear 4 through cam means 7, 8 so that overrunning of the shaft 1 by the gear 4, e.g. for engine starting, effects engagement of the friction discs, and circumferential abutment means on the cam means prevents locking or overshooting of the latter. Overriding manual disengaging means are provided. The outer discs 12 are carried by a casing 10 slidably supported on posts 16 of a plate 14 fast with the engine shaft 1. The left hand end outer disc 12 abuts a ring 13 fast with the casing 10. Separation of the casing 10 and plate 14 is effected by springs 19 and limited by washers 38 on the posts 16. The rollers 21 act between ramps 20 of the plate 14 and the right hand end outer disc 12A. The cam means comprises rings 7, 8 respectively carried by a support 3 fast with the output gear 4 and a member 6 carrying the inner discs 11 and having an inner disc abutment 9. The ring 8 has cam surfaces 34 bounded by shoulders 35, 36 and the ring 7 has claws 37 co-acting with said surfaces and shoulders. A manual disengaging means comprises a cam plate 28 which is manually rotatable by a rod 33, reacts on a non-rotatable projection 25 axially adjustable by a screw 23, and acts axially on the casing 10 via a ball bearing 32. In operation, for starting the engine, the rotated support 3 cams, by way of its claws 37 acting on the cam surfaces 34, the member 6 leftwards for the latter to engage the clutch discs 11, 12 by its abutment 9. This leftward movement of the member 6 is limited by engagement of the claws 37 with the shoulders 36, thereby preventing locking of the claws and the surfaces 34 and overshooting of the claws. If the engine starts and speeds up sufficiently for the rollers 21 to effect engagement of the clutch discs via the end outer disc 12A, the member 6 is driven from the casing 10 and the shoulders 35 are then brought into driving engagement with the claws 37. Manual operation of the rod 33 effects clutch disc release by leftward movement of the casing 10.

Title: Method of and apparatus for dewatering wet webs of papermaking fibres
IPC: D21F1/48
Filed: 1962-12-28
Abstract: 949,769. Dewatering wet webs of paper-making fibres. HUYCK CORPORATION. Dec.28, 1962 [Jan. 4,1962], No. 48777/62. Heading D2A. A wet web 29 of paper. fibres is deposited on a straight upper run 27 of a first, foraminous, synthetic fibre, moving carrier belt 23 and the upper surface of the web is then brought into contact with a second similar belt 33 and the three ply assembly so formed is caused to travel around sharply curved paths 37, 43 defined by parts of the surfaces of rotating guide rolls 35, 39, water being ejected from the assembly in passing around the rolls. Ejection of the water is the combined result of centrifugal forces and of the working of the web which results from the stretching of one (the outer) belt and the web face in contact therewith, and the compressing of the other, inner, belt and web face. The carrier belts which may for example be of nylon, or of acrylic, polyester or vinyl, fibres, allow water to be expressed freely while preventing damage to the surface of the web. Ejection of water may be assisted by causing streams of hot or cold air or other gas or superheated steam to pass through the web in the region of the sharply curved paths and to this end the roll 35 is provided with a perforated outer shell through which air is forced by air supply means 68, shown in greater detail in Fig. 2 (not shown). Since water is ejected on the upper side of the three ply assembly in its passage around roll 39 there is a danger of reabsorption of water in this region and for this reason suction means 71 are preferably provided on the outer side of the web at the roll 39. Doctors 59a and 60 may be provided to assist in the removal of water. In a modification (Fig. 3 not shown), the paper stock is discharged from pressure forming inlet means almost directly into the nip of the two carrier members which are trained, one around a breast roll and the other around a slice roll mounted above the breast roll. To provide adequate initial drainage in this case the breast roll may be of open-vaned construction. In a further modification (Fig. 4 not shown), the pulp is supplied by a vertical conduit to a first carrier belt on a breast roll and is formed and initially dewatered as it travels around a part of the circumference of the breast roll before contacting the second carrier member. Specification 827,754 is referred to.

Abstract: 1464479 Ratchet mechanism EATON GmbH & Co KG 27 Nov 1975 [5 Dec 1974] 48904/75 Heading F2Q A stepped drive for a toothed wheel 1 comprises a pawl 11 which is adapted to be swung into engagement with teeth 2 on the wheel 1, effect a driving step under the influence of a spring 21, at the end of which step it is held in engagement with the teeth 2 by a fixed abutment 3 in order to prevent over-run of the wheel 1, and thereafter is swung clear of the teeth 2 again. The pawl 11 is mounted at its upper end on an eccentric 14 which is integral with a pinion 12 which is caused to rotate about an axis 13 by teeth 24 formed on one edge of an opening 23 in a stressing lever 20. A driving motor 30 drives cams 26 through gearing 29, 25 and the engagement of the cams 26 with stressing lever 20 cause the lever 20 to pivot about a shaft 4, carrying toothed wheel 1, thereby stressing the spring 21 until the cams 26 release the lever 20 whereupon the stressing lever 20 moves clockwise under the influence of the spring 21 causing clock-wise rotation of pinion 12 and a driving step of pawl 11. Between the eccentric 14 and the pawl 11 there is a friction coupling which may comprise a spring-pressed ball, Fig. 2, or a resilient detent finger 19, Fig. 3. When the pawl 11 is clear of the teeth 2, the wheel 1 may be rotated by hand in the direction of the arrow 6, rotation in the opposite direction being prevented by a spring-pressed pawl 7.

The means 14 consists of a trolley which runs on rails 16 and carries the work member into the enclosure 10 which can be closed by hydraulically-operated doors 26, 28. The carriage is movable by an hydraulic ram 22, 24 and is connected to a second carriage 18 whereby while one carriage is in the enclosure, the other can be unloaded and loaded. The probe 30 is mounted on a carriage 34 guided for stepwise vertical movement on rails 36 and movable by an hydraulic cylinder 38. A further hydraulic motor 40 is operable to rotate the probe through 180 degrees in opposite directions. The probe head 32 carries a pair of horizontallydisposed nozzles 252, 258, Fig. 8, and a pair of inclined nozzles 260, 262, the horizontal nozzles supplying jets at a higher velocity than the inclined nozzles. Air is drawn from the upper end of the enclosure through a stack 44. An oscillating sieve 46 at the lower end of the enclosure receives used blasting medium, sand and trash, the trash being carried by a conveyer 54 to a trash box 56, and sand, dust and blasting medium drop through the sieve into a shoot 50 and elevating conveyer 52 where it is carried to a shoot 58 leading to a separator 60. The heavier blasting medium passes downwardly through a rotary screen and air washer 62 to a shot storage chamber 64 having a hopper from which the blasting medium is conveyed with compressed air by hoses 42 to the probe. The separated sand is carried by an elevator 68 and shoot 70 to a bin 72 for future use. A bag house 74 adjacent the bin has a cyclone cleaner 80 which separates coarse particles and is disposed between the air washer 62 and house 74. The house is exhausted by a fan 76 and duct 78 leading to the discharge side of the cleaner 80, the inlet side of which is connected to the stack 44. In another embodiment, the work members are carried into and out of the enclosure by an indexable table and the workpieces are rotated instead of the probe.
