Abstract: 342,777. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Dean, W. E. ; Birnam Grove, Strathfield, Sydney, Australia.) Nov. 8, 1929, No. 34174. Convention date, Dec. 7, 1928. [Class 103 (i).] In a distributing valve of the kind adapted to connect a supplemental reservoir to the usual auxiliary reservoir in the release position to accelerate the release of the brakes the supply of air from the train-pipe to the reservoirs and from the one reservoir to the other is controlled by the slide valve there being no feed groove around the valve piston. A retarded release type of triple valve is shown which with excessive train-pipe pressure provides a restricted exhaust for the brake cylinder. The train-pipe 4 connects with the piston chamber 2 by passage 3 and in the normal release position shown the main valve 9 abuts against a spring-urged stem 11 and fluid is supplied to the auxiliary reservoir 8 from the train-pipe through the passage 3 past the check valve 17, passages 18, 21, 22, 24, choke plug 23, port 25, valve chamber 6 and passage 7. The supplemental reservoir 16 is also supplied through passage 22. The brake cylinder 28 is open to exhaust through passages 27, 33, 35. A gradual reduction of train-pipe pressure causes at first movement of the piston and valve 10 relatively to the valve 9, the reservoir and brake cylinder supply ports 25, 26 being thus respectively closed and opened, the valve 9 being then moved to register the ports 26, 27 so that the brake cylinder is supplied. The train-pipe is at the same time vented to chambers 29 through passages 3, 18, 30, 31. The two chambers 29 are connected through a choke 36 for the purpose described in Specification 277,618, [Class 103 (i), Brakes &c.]. When the train-pipe pressure is increased to release the brakes the valves at the head end of the train are moved to the retarded release position in which the spring 12 is compressed and the brake cylinders exhaust through a restricted part 32 of the valve passage 33. At the rear end of the train where the rise of trainpipe pressure is less rapid the valves are moved to the full release position shown in which exhaust is effected through the unrestricted passage 33. The supplemental reservoir 16 is cut off in the application position of the valve and m the release position it is connected to and assists the charging of the auxiliary reservoir by the passages 22, 24, 25, chamber 6 and passage 7.

Abstract: 1,157,049. Variable-ratio gears. NISSAN JIDOSHA K.K. 27 July, 1967 [30 July, 1966 (2); 27 Sept., 1966], No. 34590/67. Heading F2D. A three speed and reverse planetary gear for a vehicle has its axis parallel to the engine crank-shaft and the position of an output gear-wheel substantially corresponding to the longitudinal centre of the crank-shaft so as to be suitable for vehicles having tranversely mounted engines. As shown in Fig. 1, the crank-shaft 1 drives a torque converter V having a turbine geared to a shaft 11 forming the input to a Ravigneaux type planetary gear having suns 17, 18 selectively clutchable by a forward clutch 14 and a reverse clutch 13 to the input shaft 11, the sun 17 meshing planets 19 which intermesh long planets 20 which also mesh the sun 18 and an output ring gear 21 fast with an output gear 27 which drives a differential. The planet carrier 22 is held one-way by a brake 23 and can be stationed by a brake 25. The sun 18 can be stationed by a brake 24. For all forward ratios the clutch 14 is engaged; for first gear the planet carrier is held by the one-way brake 23 (or by brake 25 for engine braking); for second gear the brake 24 is applied, the planet carrier overrunning on the one-way brake; for third gear the clutch 13 is engaged to lock the planetary gear solid for direct drive. For reverse drive the clutch 14 is disengaged, the clutch 13 is engaged and the brake 25 is applied. The gearing can be modified by positioning the forward and reverse clutches on opposite sides of the planetary gear, and with the positions of the output gear 27 and the one-way brake 23 and the brake 25 relative to the planetary gear either unaltered or reversed. In another modification of the Fig. 1, arrangement the shaft connecting the reverse clutch 13 to the sun 18 is extended to the right and the brake 24 is positioned at this end of the shaft so that this brake and the brake 25 and the one-way brake 23 are all positioned adjacent to each other at the same side of the planetary gear. The above arrangements can be further modified by replacing the sun 17 of the planetary gear by a second ring gear. In another embodiment the Ravigneaux type gear is replaced by two simple sun-ring trains; Fig. 14, showing such an arrangement having a first ring gear 52 driven by way of the forward clutch 14, a first carrier 53 fast with a second ring gear 56 and with an output gear 27, and suns 50, 54 driven by way of the reverse clutch 13 and stationable by a brake 59 for engine braking in second gear and stationable by a one-way clutch 61 and brake 62 in series to give second gear with smooth shift to third gear. A simplified arrangement omits the oneway clutch 71 and the brake 62. The positioning of the forward and reverse clutches and of the one-way brake and the associated brake may be varied for this simplified arrangement in a similar fashion as for the Fig. 1, arrangement.
