Title: An improved trigger device for fire-arms
IPC: F41A19/33
Filed: 1931-03-06
Abstract: 382,947. Firearms. TIKKAKOSKEN RAUTA-JA PUUTEOLLISUUS O. Y., Helsinki, Finland. March 6, 1931, No. 7099. Convention date, July 5, 1930. [Classes 92 (ii) and 119.] Relates to trigger mechanism of the kind comprising a sear 23 pivoted at 22, a trigger 15 pivoted at 16, a trip-lever 3 pivoted at 29 on the trigger and co-operating with the sear 23, and manually operated controlling means allowing firing of single rounds or automatic firing of a succession of rounds, and also serving to secure the breech-bolt in the safe position. According to the invention, the controlling means is in the form of a longitudinally movable slide 31 provided with a finger-piece 1 for manual operation. When the slide is in the central position shown, a pull of the trigger first depresses the sear, then releases it from the trip-lever by a deflection imparted to the trip-lever by the tail end 2 of the slide ; this results in a single round only being fired. For firing a succession of rounds automatically, the slide is shifted to its extreme forward position when the tail end 2 is out of reach of the triplever 3, so that the sear remains depressed so long as the trigger is pulled. For safety, the slide is shifted to its extreme rearward position where a lug 8 thereon comes under a shoulder 9 of the sear and prevents its depression ; simultaneously a pin 13 is wedged up by the slope 12 of the slide 31 into a notch in the breech-bolt if this is in the closed position ; so that, if the breech-bolt is in the closed position it is locked by the pin 13, and if in the cocked position it is locked by the sear's being held up by the lug 8. The pin 13 is controlled by a spring 14 and serves also to hold the slide 31 resiliently in its several positions by engagement with recesses 6, 7, 11 in the slide.

Title: Improvements in or relating to cinematographic apparatus
IPC: G03B1/50
Filed: 1962-02-23
Abstract: 950,306. Cinematographic apparatus; intermittent film feed;films. R. SCHAEFFER. Feb. 23, 1962 [March 23, 1961], No. 7236/62. Headings G2C and G2E. A cinematographic apparatus comprises a shutter, a motor for actuating the shutter, rotatable cam means incorporating a cam, to be driven by the motor, and a member, incorporating a film feeding claw, co-operating with the cam means, the arrangement being such that, during rotation of the cam means, the claw will be caused successively to move into a position for engagement with a perforation in a film, to move so as to impart two consecutive longitudinal feed movements to any film engaged by the claw, the claw coming to rest between said feed movements to effect a perforation disengaging movement and to return to its initial position in readiness for a further cycle of operation, the shutter being arranged to be opened on the completion of each feed movement. As shown (Fig. 2), an intermittent feed mechanism comprises a claw member 22 having two slots 35, 32 respectively engaged by a large headed stud 36 and a machined end of a shaft 30 of a cam disc 24. The claw member carries a roller 21 engaging the cam disc 24 under loading of a spring 26 coiled around a projecting part of the member 22. Shaft 30 with disc 24 are rotated to effect feeding of the film through a gate 25. Movement of the claw on member 22 into and out of the film perforations is controlled by the machined end of the shaft 30. The cam steps on disc 24, in co-operation with the roller 21, move the claw in its two feed movements and also return the claw to its starting position prior to each feed cycle. The two exposures take place while roller 21 is traversing arcuate surfaces 38, 23. The shutter comprises a slotted drum 20 which is prevented from rotating in the position of Fig.2 by a lever 17 engaging a pin 18 on a flywheel 19. The lever may be pivoted out of the way by a release button 33. The shutter and disc 24 are coupled for synchronous rotation by means of toothed gearing 8, 7 and 9 (Fig. 1). Both are coupled to a driving motor mounted on a shaft 3 through toothed gearing 7,4 and 3<SP>1</SP>. The Specification also refers to a weight-type speed governor 10, set manually by a screw disc 13, and coupled to the shaft 30 through gears 11 and 12. There is also a driving connection from the motor through gears 3<SP>1</SP>, 4, 6 and 14 to a rewind shaft 15 having a friction coupling with a claw 16. The image arrangement produced by exposure of film in a camera in accordance with the invention is shown in Fig.6 at 41 and 42 (39 merely representing the prior art arrangement). In this case, the sprocket holes 40 are central and a wide space 43 is left for a sound track.

Abstract: 1,088,571. Discharging from aircraft. PLESSEY-UK Ltd. Feb. 11, 1965 [Feb. 21, 1964], No. 7358/64. Heading F3C. A store is retained on an aircraft by lugs A thereon engaging hooks 43 pivoted at 51 and held in position by sears 11. When a cartridge is fired in breech 4 gases expand into reservoirs 12, 13 to build up the pressure therein to the near-maximum at which value a piston 32 is actuated to move the sears 11 from their locking position so that the hooks may pivot to release the store. At the same time the pressure in reservoirs 12, 13 is acting on pistons 17 which abut the top of the store and act to eject the latter on its release. The sears 11 are connected by levers 10 and tie rods 25, 30 to two pivot points 25a, 30a on a shaft member 26 which is prevented from rotating by a safety lock 46. An electric actuator 44 is provided to initiate the release and ejection of the store, the lock 46 being first pivoted out of the path of the member 26 and a micro-switch 47 then being operated to fire the cartridge in breech 4. Gases expand into reservoirs 12, 13 and pass through adjustable orifices 15, 16 to above the pistons 17 and also through restrictions 49 and 6 into the cylinder 7a and hollow piston-rod 7. When the pressure in reservoirs 12, 13 has built up to the near-maximum piston 32 moves against spring 29 to rotate member 26 and so release the sears from their locking position. The pressure above pistons 17 cause the latter to move downwardly rapidly to eject the released store, the gases in cylinder 7a and piston-rod 7 being trapped and compressed. When the store has moved away from the piston end 22 a valve sleeve 8 may move downwardly to release the pressure above the piston 17 through bore 9, after which the gas compressed in piston-rod 7 can move the piston upwardly to its original position in which it is retained by a ring 36.

Abstract: 1,021,684. Breathing apparatus. NORMALAIR Ltd. Feb.18, 1964 [Feb. 23, 1963], No. 7368/63. Heading A5T. Breathing equipment for an aviator includes housing 3 having associated therewith a demand regulator 5 and having a large bore connection, to which is fitted hose 2 leading to mask 1, and a small bore high pressure oxygen supply pipe 9, adapted to be connected to an oxygen pressure source on the aircraft, the housing 3 being adapted to be worn on the front or side portions of the user's torso. The housing 3 has an air inlet valve 6, the airflow to which is prevented by a spring- controlled shut-off valve 7 when the supply pressure to the regulator 5 is above a predetermined value. The housing 3 may be connected to the wearing apparel of the user by connections 10,12. Pipe 9 is connected to the oxygen supply via a control box 14, in which the supply pipe has an orifice 15. By-pass lines 16, via manual and aneroid-controlled valves 17 and 18, are provided. Hose 2 may be connected by connection 4 to an additional oxygen supply. In use, oxygen is supplied at a predetermined pressure to regulator 5. An inhalation regulator 5 opens and oxygen enters housing 3. The oxygen supplied is insufficient to meet the demands, so inlet valve 6 opens as a result of a drop in pressure in housing 3 and pipe 9. When the aviator requires a 100% oxygen supply, the manual valve 17 or aneroid valve 18 is opened. This results in the pressure in pipe 9 being above the predetermined valve, so shut-off valve 7 closes and no air reaches valve 6.
