Patent GB-485547-A (GB)
Title: Improvements in charging blowers for internal combustion engines
IPC: F04C28/12
Filed: 1937-12-03
Abstract: 485,547. Rotary compressors. BOSCH AKT.-GES., R. Dec. 3, 1937, No. 33423. Convention date, Dec. 31, 1936. [Class 110 (ii)] The quantity of fuel gas or air supplied by a rotary blower to an internal-combustion engine is controlled in accordance with the engine speed by spring-loaded valves inside the blower pistons. Pistons 1, 2 are driven by the engine through a gear 8 and gears 9, 10, on the shafts 3, 4 to supply fuel gas or air from an inlet 24 to a delivery port 22. In the example shown in Figs. 1, 2, gears 9, 10 pump fluid through passages 26, 11, 12, to spaces 13 to force valves 17 to the right. As the engine speed increases, and the speed of shafts 3, 4 consequentially, the valves 17 move until ports 19 line up with ports 20 in the pistons 1, 2, and allow a passage of fluid from the compression chamber 22, to the suction chamber 24. Where the blower is delivering air to the engine, excess air passing into the port 20 may be led to atmosphere by way of a channel 28. A pin 29 in a slot 30 prevents rotation of each valve 17, which may be hollow. Fig. 4 shows a modified blower in which a spring-pressed valve 45 in each piston is actuated in its axial movement by a rod and bell-crank lever, controlled, for instance, by a centrifugal governor. Fig. 5 shows how the byepass passage in each piston is controlled by a valve 54, which under centrifugal action is flung outwards and overcomes the pressure of a spring 53. In a further arrangement the valve is a segmental plate on an arm, and normally held in a position covering one port 52 by a coiled spring. Centrifugal force causes the valve and its arm to rotate and gradually uncover the port 52.
Patent GB-479701-A (GB)
Title: Improvements relating to indexing mechanisms
IPC: B23F23/08
Filed: 1936-12-05
Abstract: 479,701. Indexing-mechanism. GEAR GRINDING CO., Ltd., ORCUTT, A. H., and BULLOWS, R. J. Dec. 5, 1936, No. 33430. [Class 83 (iii)] Indexing - mechanism particularly for a spindle a carrying a heavy work-piece comprises a toothed or notched indexing-plate b which is actuated intermittently with slight over-travel by an oscillating pawl e, the plate movement being resisted by a friction brake which is restrained by resilient means whereby energy stored in the resilient means is used after cessation of the pawl movement to impart a slight reverse movement to the plate to move same into correct engagement with an independent positioning - pawl u. The teeth c of the plate have one radial face d. The actuating-pawl e is mounted on an arm f which is connected by a rod i and member m to a crank disc o on an operating- shaft p. When the latter is actuated the pawl e rotates the indexing-disc through slightly more than the desired distance while the positioning-pawl u moving on a stationary pivot rides idly over the rear face of each tooth. A brake drum w on the spindle is engaged by a pair of brake shoes which are adjustably held against the drum by a spring 2. When the indexing-disc is rotated, it tends to carry the brake shoes round with it thereby causing a stop 7 carried by lugs 8 secured to one of the shoes to compress a spring 6 on a rod 5, supported by a bearing member 9. As soon as the pawl e begins its return movement the spring 6 acts on the stop 7 to give a short return movement to the index disc thereby forcing the radial face of the operative tooth against the positioning-pawl u for accurately determining the indexed position. The index disc is adjustable relatively to the spindle by means of screws 21 carried by the part 20 of a retaining member 17 'and coacting with a rod 22 secured to the disc. The brake shoes may be disengaged from the drum when required by means of a rod 11 having a handle 14.
