Title: Improvements in machines for producing vents in cartridge-cases
IPC: B21D28/32
Filed: 1944-06-29
Abstract: 580,327. Making cartridge-cases. ABBEY, A. (Arenco Aktiebolag). June 29, 1944, No. 12426. [Classes 83 (ii) and 83 (iv)] Punching; punches.-A machine for producing a vent in cartridge-cases comprises a holder for a punch, a punching die positively movable relatively to the holder and having a hole in it of, preferably, about 50 per cent larger diameter than that of the punch, and' a feed-mechanism for advancing the cartridgecase and mounting it on the die. Cartridgecases from a magazine 11 are moved laterally by a pusher 10 between a punch 6 mounted in a fixed holder 5 and a positively reciprocated die 7. Slidably mounted on the punch holder is a sleeve 19 with a projecting portion 20 adapted to fit the depression in the base of the cartridge-case and with a flange 21 for guiding the case into the correct punching position. As the die 7 is advanced towards the punch it enters the .open end of the cartridge-case, moves it into position against the end of the sleeve 19 and, on further movement, pushes back the sleeve against the action of a spring 22 so that the punch passes through the base of the cartridge-case. The punch passes through a bore in the end portion 20 of the sleeve 19 so that it is guided right up to the work. The work is stripped from the punch by the sleeve 19 and the removal of the cartridge-case from the end portion 20 is assisted by a cam-operated finger 26. After a punching operation, the die 7 is retracted and a cam-operated feeler 29 enters a hole 35 in the flange 21. If the punch has been broken and the movement of the feeler is not arrested by contact with the punch, it swings over until contact is made between contact members 36 and 37. This energizes a solenoid to release a locking pawl which then prevents a further work-feeding movement of the bar 12 carrying the pusher 10. Alternatively, the feeler may operate a warning signal or a device for segregating cartridge-cases delivered after the fracture of the punch. Preferably, a plurality of punches and dies are arranged side by side and are fed with.cartridges from separate magazines by a common feed bar 12.

Title: Improvements relating to fuel feeding systems for internal combustion engines
IPC: G10F1/02
Filed: 1930-04-23
Abstract: 352,128. Vacuum engines; valve-gear. TRICO PRODUCTS CORPORATION, 817, Washing- ton Street, Buffalo, New York, U.S.A. April 23, 1930, No. 12529. Convention date, Feb. 26. [Classes 122 (ii) and 122 (iii).] Fuel is raised from a low-level tank to a carburetter 3 by a suction actuated diaphragm-type pump, Fig. 2, housed in the upper part of a filter chamber 7, means being provided to maintain a constant degree of suction independently of the depression existing in the induction pipe 1. Fuel enters at 4<1>, Fig. 2, and flows through a non- return valve into a detachable glass filter chamber from which it is forced by a pulsating diaphragm 12 through a further non-return valve 20, to an outlet 4 leading to the carburetter 3. The fuel-lifting movement of the diaphragm is effected by the opening of a valve 26 which puts a chamber 11 on the dry side into communication with the intake manifold, the delivery being effected, on the opening of a valve 24 admitting atmospheric pressure, bv the action of a tension spring 27 attached to the underside of the diaphragm. The alternate actuation of the valves 24, 26 is effected by the movement of the diaphragm through a snap-action device, comprising a helical spring 35, Fig. 6, in which a limited transverse flexure takes place until the tension is sufficient to arrest the valve, thus ensuring the quick opening of one valve and closing of the other. The depression in the induction pipe is transmitted to the chamber 11 via a cylinder containing a spring-loaded plunger 44, Fig. 1. When the engine suction is low the plunger 44 moves upward under the action of its spring until a stem 45 engages a rocking arm 48 actuated by the engine ; the plunger being thus reciprocated draws air from the chamber 11 through a suction non-return valve 53 and forces it past a delivery non-return valve 54 to the induction pipe. The lower end of the plunger stem 45 is provided with a valve face 55 which may coact with a seating 56 formed in the upper end of the outlet passage from the suction pump chamber, the purpose of the valve 55 being to reduce by throttling, the suction transmitted to the pump when the depression in the induction pipe is excessive ; a groove in the seating prevents the valve 55 from entirely closing the passage. The pump diaphragm 12 is of fabric, clamped at its centre between metal discs 101, and it is so arranged that it is always bellied towards the dry side, i.e. reversed flexure cannot take place.

Filed: 1953-05-07
Abstract: 736,451. Fluid-pressure servomotor-corstrol systems. ROOSA, V. D. May 7, 1953, No. 12783/53. Class 135. [Also in Group XXVIII] A device for automatically controlling the timing of an engine fuel injection pump of the one or more pump pistons 16 are moved radially as a result of circumferential movement relative to a cam 20 which is for the most part stationary, comprises a liquid-driven piston 50 for adjusting the position of the stationary cam, a passageway including a non- return valve to provide a fluid connection between a feed pump 30 and the piston 50, and a further passageway permitting a slow release of liquid from the rear of the piston 50 to eliminate " fluttering " or " chattering " of the device under rapid or frequent changes of engine speed. The adjustable cam 20 with high parts or lobes 21 is mounted within the main pump casing 10 and surrounds a rotary member 12 driven from the engine through a gear 13. The member 12 has a transverse bore 15 containing opposed pump pistons 16 urged outwardly against shoes 17 supporting rollers 18 by centrifugal force and the pressure of liquid in the bore 15. An arm 47 on the cam 20 projects into a transverse bore 41 in the main housing 10 and is engaged on one side by a spring-loaded plunger 51 and on the other by the piston 50 exposed on its outer end to fuel pressure supplied by the feed pump 30 which may be a sliding-vane or gear-type pump. The rotary member 34 of the feed pump is rigid with a fuel-receiving and distributing member 25 itself rigid with the rotary member 12. The delivery of the feed pump 30 passes through passages 32, 33 to a non-return valve mounted in a screw-threaded support 57 and thence through passages in the support and a passage 55 to the rear or outer face of the piston 50. A small clearance between the piston 50 and the bore 41 permits fluid to pass gradually from the rear of the piston and thence through an axialpassage 65 in the arm 47 when the engine speed decreases. and the plunger 51 moves the cam 20 to retard the timing thereof. An increase of engine speed correspondingly causes the piston 50 to rotate the cam 20 in a direction to advance the timing thereof. Specification 656,906 is referred to.
