Patent GB-728926-A (GB)
Title: Improvements in or relating to control mechanism for the transmission systems of motor vehicles
Inventor: BOTHAMLEY FREDERICK HENRY
Filed: 1952-10-07
Abstract: 728,926. Controlling clutches; change-speed gearing. AUTOMOTIVE PRODUCTS CO., Ltd. Oct. 7, 1953 [Oct. 7, 1952), No. 25140/52. Addition to 715,747. Class 80 (2). In a motor-vehicle transmission system as shown in Fig. 6 of Specification 729,041, a normally-closed switch 75 controlled by the handbrake lever 78 is arranged in series with the gear-lever-operated switch 71. When the bandbrake is engaged, switch 75 is opened, thus pre. venting energization of the clutch servo 15 and limitation of the throttle opening and enabling the engine to be speeded-up, with the gear in neutral, for warming or testing purposes. The clutch is engaged by springs controlled by centrifugal weights so as to be effective above a predetermined speed of the driving member, the limited travel of the clutch throw-out lever 23, due to its connection to the servo 15, preventing engagement below that speed. In order, therefore, to allow the engine to be started by towing the vehicle, the arm 22 of the lever 23 comprises two parts 47, 48 pivoted together at 22a and normally held rigid by a catch comprising a notch 49 in part 48 engaged by a pin 51 on a member 52 pivoted at 53 on part 47, and this catch can be released through a Bowden-wire 54 and a spring 58 by operation of a hand lever 57, accompanied by a temporary depression of the usual clutch pedal, thus freeing the lever 23 from restraint and allowing the clutch to engage independently of the centrifugal weights. When so operated, lever 57 opens a normallyclosed switch 76 arranged in series with the switch 73 closed when the clutch-driven member over-runs the clutch-driving member, so that the servo 15 and the throttle-opening servo 45 are maintained de-energized.

IPC: A01K43/00
Filed: 1950-10-17
Abstract: 689,918. Eggs cleaning. CHURCH, G. T. July 19, 1951 [Oct. 17, 1950], No. 25260/50. Class 28 (ii). [Also in Group XXX] In an egg &c. cleaning machine in which each egg is conveyed longitudinally between revolving brushes 23a and 23b the egg x is rotated and also pressed down and held on a conveyer 16 by the brushes by one or other action as follows: -the brushes may be oppositely rotated : they may be rotated in the same direction, one brush then having more numerous or stronger bristles than the other: the downward moving brush bristles may have a higher rotational speed than the other. The brush axes may be slightly higher than the egg axes. The brushes may dip into a washing liquid tank 40. Such tank may be short to wet only the first part of the brushes or may comprise two short section tanks one for washing liquid and another for rinsing liquid, the unwetted latter part of the brushes acting to dry and polish the eggs. The tank has a removable cover 41. If the brushes operate without a liquid the bristles may be of wire. Each egg rests on a concave central limb 18 of the conveyer and is supported at its sides near its ends between pairs of inwardly curved fingers 20 mounted on outer side limbs 17 of the endless conveyer. The conveyer is driven slowly by worm 29 and toothed disc 30 from one motor driven shaft of the brushes e.g. 24b. Alternatively the conveyer may be made of textile or flexible material with means for preventing sideways rolling off. The eggs x are delivered to a rubber covered shoot 33, Fig 3, and then to a drum 34 with spaced rubber ribs 35 to receive each egg in the spaces. The shoot 33 may be replaced by an endless drying towel.

Title: Improvements in wrapping machines
IPC: B65B11/54
Filed: 1949-10-03
Abstract: 673,995. Feeding webs. STEPHENS, SMITH & CO., Ltd., and WALSH, T. E. Oct. 3, 1950 [Oct. 3, 1949; May 10, 1950], Nos. 25331/49 and 11649/50. Class 100 (i). [Also in Groups VIII and XVII] A strip of wrapping paper 21 is fed by co-operating intermittently rotating rollers 62, 63 beneath knife means 64 onto a support 22 of a fruit wrapping machine, (see Group XVII), a wrapper sheet being cut from the end of the web when stationary. The feed rollers 62, 63, which are geared together, are driven from a ratchet wheel 75 intermittently turned by a pawl 76 which is pivotally carried by a triangular plate 81 loosely mounted on the shaft 82 of the ratchet wheel 75 and oscillated 180 degrees by a connecting rod 83. A catch 88 in the form of a bell crank is pivotally carried by the plate 81. At the end of the down driving stroke of the pawl a roller 87 carried on the pawl contacts a stationary adjustable cam member 92 to move the pawl out of engagement with the ratchet wheel, a pin 86 on the pawl slipping into a notch 91 in the catch 88 which then holds the pawl out of contact with the ratchet on the upstroke until the catch engages a trip 93 to release the pawl from the catch and allow a spring 90 to pull it into contact with the ratchet wheel for the down stroke. The trip 93 is carried by a lever 117 which moves the trip out of the catchengaging position if an article is not present to be wrapped, thus interrupting the drive to the feed rollers 62, 63. The lever 117 is normally held in the catch-engaging position by the cylindrical part of a cam 119 and, when the profiled part of the cam comes opposite the end of the lever, by a feeler 116 secured to the lever and held up by an article to be wrapped. If no article is then present the lever will move into contact with the profiled part of the cam and move the trip 93 out of catch-engaging position. A serrated knife 105 and presser 104 are carried by a block 106 moved on guides 107 by lever and link means 111, 112 actuated by a cam 114. A band 127 above the web feed bed prevents crinkling of the web. The cam 92 is mounted on a plate 94 adjustable about the shaft 82 to vary the stroke of the pawl and thus the amount of the web fed by each intermittent rotation of the feed rollers 62, 63.

Title: Process of, and apparatus for, producing sheets of raw rubber with thread insertions for velocipede or automobile vehicle tyres
Filed: 1924-10-25
Abstract: 223,934. Debor, H. Oct. 26, 1923, [Convention date]. Elastic fabrics.-Rubber sheets having parallel threads embedded in one or both surfaces are produced by mounting the sheets d on the periphery of a revolving drum a, and winding a continuous thread n thereon in a helical coil. The thread is received in a groove cut in the sheet by a knife m pressed by a spring against the drum. The knife may be electrically heated. The thread n is fed to the drum over guide rollers l attached to the knife, and it may previously be passed through a bath, of rubber solution g. To prevent stretching of the rubber by centrifugal force the drum may have a perforated surface and may be exhausted through the hollow shaft s. When the winding is completed the rubber may be distended by admitting compressed air, steam, or other gas into the drum so as to cause the threads to become more firmly embedded. This effect may be increased by heating the drum or the gases admitted to it.

Continuous-discharge apparatus with stationary containers. - In grinding and mixing mills for mortar &c., of the type comprising a cylindrical casing containing a rotary central shaft carrying a series of grinding and mixing runners that can move radially and rotate on their own axes, the runners extend the whole length of the casing and are constructed so as to convey the material from the feeding to the outlet end of the mill. As shown, Figs. 1 and 2, the central shaft 7 carries end plates 13, 14 having four radial slots 16 to receive sliding blocks 35 which carry the shafts 17 of the runners 18. The blocks 35 may have trunnion-like extensions slidably engaging grooves in the edges of the slots 16. Two of the runners 18 are provided on their front ends with right-handed threads which extend over about one-half of the length of the runner and the depth of which decreases towards the rear. The third runner has parallel circular grooves on the front half of its length while the fourth runner has a left-handed thread on the rear half of its length. All the runners are slightly conical with their larger ends towards the front of the mill. The open rear end 11 of the casing 1 forms an enlarged hollow portion 29 which contains a ring conveyer 27, 28 bolted to projections 26 of the rear plate 14. A false bottom of resistant material is provided in the lower part 2 of the mill. The materials to be treated are introduced through a feed-hopper 22, which may be fitted with a spray pipe 23, at the front end of the mill, and the disintegrated and mixed materials are discharged by the conveyer 27, 28 through a sleeve conveyer 31 to the outside of the mill. In a modification, Fig. 5, the front plate 13 is provided with one or more scraper plates 33 to facilitate the feed, and series of inclined scraper plates 45, Fig. 6, may extend from the front plate 13 to the rear plate 14 and between the runners. The plates 45 may be pivoted to a rod 42 secured to the plates 13, 14. and also to a parallel rod 43 which is adjustable longitudinally to vary the inclination of the plates. One or more scrapers 33<x> on the rear plate 14 direct the treated material into the outlet conduit 40. When treating moulding sand, some of the runners 18 may be replaced by runners consisting of end discs carrying longitudinal crushing-bars of circular, ovoidal, or other section. In some cases, cylindrical runners with parallel circular grooves are used.
