    • 20,275. Anderson, H. P. H., and McCallum, J. Sept 28. Machine guns.-Relates to machine guns having a recoiling barrel, and consists in providing a revolving breech chamber, the cartridge case crossing the line of contact between the barrel and breech chamher to prevent escape of gas. In the form shown, the involving breech chamber 3 is pivotally mounted in a cage 2 which is removably attached to the barrel through the medium of a two-part member 31, the barrel and cage recoiling together, against the action of a spring 22, in the casing 1 of the gun. The breech-block 10 is moved relatively to the cage 2 to open the breech by the depression of a lever 17 caused by the engagement of a pin 18 thereon with a fixed groove 19, the lever actuating the block through a pin 16 and grooves 15. As the breech-block moves rearwards, the firing-pin 11 is cocked by the engagement of a lever 14 with a fixed stop 20 and held by a sear 13, and the breech chamber is rotated one step by the engagement of an arm 7 with an incline s. Hinged flaps 4, Fig. 2, carried by the breech chamber are actuated by the engagement of a pin p on each flap with a cam-groove c on the cage. The hinged flaps in turn (1) open to receive a cartridge from a belt or hopper 34, (2) close when the cartridge is in line with the barrel, and (3) reopen to discharge the spent case. The forward movement of the case which follows recoil causes the breech to close, the extractor e snapping over the rim of the cartridge case. The gun can then be discharged by acting on the sear 13 through a sliding rod A moved by a trigger B. The rod A may be actuated from a distance by means of a Bowden wire. The member 31 surrounding the barrel may act as a pump plunger to drive air through a passage o to cool the barrel. A hand-lever 24 enables the cage 2 to be moved rearwards to start the gun, hut afterwards the gun will fire automatically so long as the trigger B is kept pressed.

    • 15,517. Anderson, H. P. H. July 3. Operating swinging and sliding doors.-Relates to hydraulic apparatus for operating bulkhead and other doors from a distance, or locally, in which the local control may be effected automatically by the rise of water in the bilge, and consists (1) in employing a closed liquid circuit through which the operating-liquid is circulated, (2) in an improved construction of the distributing-valves, and (3) in improved means for automatically actuating the local control valve from the rise of water in the bilge. Figs. 1, 2, 3 and 4 show a section through the apparatus. A double acting pump A, driven by a direct-acting engine, for example of the Worthington type, is connected by pipes 1, 2 to a main control valve-box which consists of four chambers B, C, 8, 11. The chamber 8 communicates with the chambers B, C through valves 4, 5 respectively, and also with the chamber 11 by a port as shown. The chambers B, C also communicate with the chamber 11 through valves 3, 6. The chamber 11 contains a hand-actuated piston-valve 7 which controls ports to two mains 12, 13. Near each door is provided a local control valve-box, Fig. 3, connected to the mains by pipes 16, 17. The local control valve is connected by passages 18, 19 to the ends of the door operating cylinder or cylinders. A valve 20 in the inlet passage from the pipe 17 to the local valve is normally kept open by resting upon an enlargement of the shank of the valve 21, but can fall to its seat when the valve 21 is pushed sufficiently far to the left. A by-pass 23 leads from below the valve 20 to a chamber 24 into which the spindle of the valve 21 projects. The whole system is supplied with liquid through the supply valves S in the pump A, and steam is continually on the engine driving the pump. The pump piston moving in the direction of the arrows, the liquid passes through a pipe 1, valves 6 and 7, pipes 12 and 16, and the local valve 21 to a pipe 18 and the top of the piston 14, thereby opening the door. The liquid on the other side of the piston 14 is forced through a pipe 19, around the valve 21, through pipes 17, 13, around the valve 7, and through valve 4 and a pipe 2 to the pump. On reversal of the pump stroke, the liquid passes through the pipe 2, valve 3, and pipe 12, and thence to the top of piston 14 as before. When the piston 14 reaches the end of its stroke, the pump stops. To close the doors from the main valve, the latter is pushed over till the passage 12 communicates with the chamber 8 around the valve 7. To close the door locally, the valve 21 is pushed over till the passages 18, 17 communicate with each other round the valve 21. The local operator may prevent the door from being opened from the main valve by pushing the valve 21 over till the valve 20 closes. Pressure through the pipes 13, 17 is then unable to pass the valve 20, and the door remains closed. The local valve is automatically operated to close the door on the rise of water in the bilge by means of a spring-controlled lever 26, bearing upon the end of the valve spindle and held in its normal position by means of a catch 27, Fig. 5, bearing upon a diaphragm 28. The other side of the diaphragm communicates with the bilge through a pipe 29 having an enlarged lower end. The rise of water in the bilge compresses the air in the pipe 29, thereby distending the diaphragm and releasing the catch 27. The door may be kept in a partlyopen position by pushing-over the valve 21 till both pipes 18, 19 are closed. The door may then be closed from the main valve by pushing the latter over to the left. The pressure in pipe 17 then passes through the by-pass 23, and, acting on the end of the valve spindle, forces the valve to the right and admits the pressure to the bottom of the piston 14. The local valve may be omitted and the pipes 18, 19 connected directly with the mains 12, 13. The whole or part of the system may be duplicated, and instead of the double-acting pump A rams may be employed.

    • 2726. Anderson, H. P. H. Feb. 5. Sluice gates.-Relates (1) to means for operating sluice gates, heavy shutters, or other sliding closures for apertures, of the type in which there is no contact between the jointing - surfaces during the sliding of the shutter &c., white the latter is forced into close contact with the frame when driven home by the continuation of the closing- movement, thus making a water-tight joint, and (2) to the use of an outer shutter with a sliding window or closure operated in the above manner. The shutter 9, Fig. 1, is closed by means of bevelgearing 7, 6, screw gearing 3, 5, and worms 2 operating racks mounted on bars 10 attached to the shutter by parallel-motion links 11. The bars 10 slide in channels in the frame so that they are not free to move in a direction at right-angles to their length, while the shutter slides on projections 12 until it is just closed. When the shutter has cleared these projections and its motion has ceased, the continuation of the closing movement forces the bars 10 farther homo and thus, through the parallel motion, drives the shutter upon its jointing-surfaces. The shutter &c. 13, Figs. 4 and 6, is closed in a similar manner, but in addition it is fitted with a door 16 sliding through a slot 17 in the same frame. This door is operated by bevelwheels 19 from gear 21, or, by means of the friction gear shown in Fig. 7, the shafts 4, 20 may be operated independently from the same driving- gear 24. A shank 35 on the bevel-wheel 25 passes through the two screw gears 26, 27 and carries a cone 30, which may be made to slide on a rod 31 and thus to mesh with either gear by adjustment of a nut 34 which screws into the shank 35 and on the rod 31.
