Filed: 1916-10-03
Abstract: 106,579. Vanderlip, W. B. Oct. 3, 1916. Generating by direct contact of combustion products.-In generating gases under pressure for power or heating purposes by the explosion of charges of nitroglycerine &c., a valve between the explosion chamber and the storage chamber for the gases is mechanically freed or unseated synchronously with the firing of the charge. The explosion chamber 10 is formed in a water-cooled block 9 and communicates with a storage chamber 2 through a flared opening 11, which constitutes a seating for the valve 61a. The cartridges 38 containing the explosive are stored in a magazine 39 and are dropped one by one in front of a reciprocating ram 14, which pushes them through the tube 14<1> into the firing-chamber. The ram is locked in position by a slotted-vertically-reciprocating breech-block 31, which engages reduced portions on the ram, and the charge is fired by a pin 15. The cartridge shell is withdrawn by a spring finger on the ram and is ejected through the opening 73 when it contacts with a spring stop 74. The magazine is controlled by slides 40, 40' nterconnected so that when one is open, the other is closed. The lower one is opened by a pin on the ram during the return stroke, and is closed again by a spring. The valve 61<a> is carried by a frame 63, from which extend guide-rods 64 moving in glands 64<1> and connected to a spring-controlled frame 65. The firing-pin 15 is struck by a hammer 50 operated bv a cam 55 on the wheel 57, and simultaneously the frame 65 is engaged by the tappet 68 and the valve is unseated. The full opening of the valve is effected against the pressure of the springs 66 by the exploding charge. The ram is reciprocated by a bell-crank lever 16 operated from a crank-pin on the wheel 24, and the breech-block is reciprocated from a gear-wheel 35<1> through a link 35. The storage chamber 2 is strengthened by stays 4 and an inner perforated chamber 3, and radiation of heat is prevented by double walls A, B, between which a partial vacuum is maintained by an ejector 5. The temperature of the gases may be reduced by supplying water under the control of a thermostat 77.
