Patent GB-617648-A (GB)
Title: Improvements in and relating to apparatus for starting internal combustion engines
IPC: F02N13/00
Filed: 1946-10-08
Abstract: 617,648. Starting. BRITISH THOMSONHOUSTON CO., Ltd., GRAHAM, D. H., TABBERER, G., and FORSLING, B. E. G. Oct. 8, 1946, No. 30031. [Class 7 (v)] In an internal-combustion engine starter, such as used on aircraft, in which gases from an explosive cartridge drive a turbine coupled to the engine, the starter is provided with a cartridge magazine, in order to avoid the use of a rotary firing breech and being so constructed that the gases under pressure produced by the cartridges will be effective to drive the turbine whether the cartridges are fired singly or two or more together. Between a platform 2, which is mounted on the turbine casing 9 and supports a sealing plate 3 by means of pillars 4, is secured a number of cartridge chambers that are made up of two parts 5, 6, one sliding in the other and sealed by means of split rings. Light springs maintain the ends of the cartridge chambers in contact with the platform 2 and sealing plate 3 and additional pressure is supplied by the cartridge gases Each cartridge chamber is connected through a pipe 8 to a separate turbine nozzle. Spring- loaded electrical contacts 10, one for each cartridge chamber, are mounted on the sealing plate 3 and may be connected in circuit by means of a cockpit "ON and OFF" switch and a selector switch 15 mounted on the turbine. When the cockpit "ON and OFF" switch is closed, a solenoid 12 is energized thereby moving a driving dog 13, on the end of an engaging rod 11, into mesh with the engine. Movement of the engaging rod 11 in addition to compressing a spring also causes a bar 16 to rotate a ratchet-wheel 19 through 45 degrees by means of two pawls 17, 18. One of four cams 20 on the ratchet-wheel spindle closes one of four pairs of contacts 21, 22, one contact of each pair being connected to a battery whilst the other is connected to a cartridge electrical contact 10. Each cam lobe is displaced 90 degrees relative to the next so that when the solenoid is de-energized, the compressed spring brings the driving dog out of engagement with the engine and the bar 16 causes the ratchet-wheel 19 and cam 20 to rotate a further 45 degrees therefore allowing the contacts to open. This sequence is repeated for the next contact pair so that the selector switch is always in the "OFF" position when the starter is not in use. If it is required to fire two or more cartridges simultaneously, the remote selector switch is replaced by an " ON and "OFF switch and a selector switch is placed in the cockpit. Specification 514,977 is referred to.
Patent GB-537293-A (GB)
Title: Improvements in change-speed gearing
IPC: F16H61/02
Filed: 1939-11-14
Abstract: 537,293. Variable-speed gearing. BRISTOL AEROPLANE CO. Ltd., and OWNER, F. M. Nov. 14, 1939, No. 30074. [Class 80 (ii)] In an epicyclic variable-speed gear in which the planet carrier is the driving member and the annulus the driven member, the sun wheel may be locked against rotation to produce a high gear or clutched by centrifugal means to the planet carrier so that the gear is solid to produce a low gear. As shown the planet wheels 15 are mounted in a carrier 13 having a gear 11 driven from a gear 10. The sun 16 is formed on a sleeve 17 and is splined to a sleeve 25 carrying clutch plates 26 spaced by a plate 27 splined to a fixed casing 28. The latter carries a piston 29 upon which may act hydraulic pressure admitted into the casing 28 through a port 31 to engage the clutch and hold the sun 16 stationary. A casing 19 mounted on bearings 20, 21, has an internal gear 18 engaging the planets and an internal gear 22 egaging a gear 23 on a driven shaft. The planet carrier 13 has a grooved ring 35 forming the outer member of a centrifugal clutch, the inner members of which are constituted by masses 36 yieldingly secured to the sleeve .17. In operation and when the clutch 26, 27 is engaged a high speed is obtained by the planets planetating round the fixed sun 16 and so driving the casing 19. If the clutch 26, 27 is disengaged the sun 16 will commence to rotate, the masses 36 are thus moved outwardly to engage the ring 35 and the whole of the epicyclic gear becomes solid to produce a low gear. A number of such epicyclic trains may be arranged around a central gear 23 which may be on the shaft of a super-charger of an internal combustion engine.

Title: Method of lubricating loose wheels of vehicles, particularly railway vehicles, and lubricating devices for carrying out this method
IPC: H01K1/16
Filed: 1933-10-30
Abstract: 407,897. Rotary pumps. HUGUENIN. A., 319, Hardstrasse, Zurich, Switzerland. Oct. 30, 1933, Nos. 30099, 30100, and 30101. Convention dates, Nov. 9, 1932, May 11, 1933, and Aug. 22, 1933. [Class 110 (ii).] A loose wheel of a vehicle is lubricated at low speeds by means of a rotary pump comprising a cylindrical casing 90 which revolves with the wheel 79, an eccentric disc 83 secured to the fixed axle 61, and a spring-pressed plunger 95 in the casing 90. As the wheel rotates the plunger 95 forces lubricant from the crescentshaped space 97 into passages 65, 66, in a hollow member 62 in the axle 61 from whence it passes to recesses 99, 101, in the bearing faces. At the same time lubricant is drawn through recesses 102, 104, into passages 67, 68 in the member 62 and thence into the space 97. When the speed of the wheel exceeds a predetermined amount the plunger 95 moves outwardly under centrifugal force and the rotary pump ceases to act. The wheel is then lubricated by lubricant, which is carried round in a casing 86 secured to the wheel, being trapped by a catcher 88 and passed through an axial passage 71 in the member 62. This lubricant then passes up a passage 75 in a header tube 73 and flows down passages 76, 77 to an axial passage 72, communicating with bores 78 leading to the bearing surfaces. The passages 66, 67, also lead to passages in the tube 73. A spring packing ring 94 tends to keep lubricant from the chamber 110 of the casing 86 and thus keep the pump passages filled with lubricant even when the wheel is stationary. More than one rotary pump 83, 90, and oil catcher 88 may be used on a single wheel, the pumps being arranged out of phase. In a modification the member 62 has only two axial passages and these are interconnected at the header 73 by a throttling passage.
