Abstract: 254,195. Szilvay, K. Dec. 22, 1925. Fire-engines; fire-extinguishing by pulverulent materials.-In the extinguishing of fires by a refractory powder, the powder is blown on to the fire by the exhaust gases from an internal-combustion engine. As shown applied to a motor vehicle, the apparatus comprises a hopper 1 from which powder is supplied by a conveyer 2 to a nozzle 3. The exhaust gases from the engine 4 pass by a pipe 5 to a tube-cooler 7, through which cooling air is drawn by a.n exhauster 15, and are compressed in a compresser 9 and passed to a casing 12 around the nozzles 3.

A known toggle operated collapsible undercarriage on a fifth wheel coupled trailer, Fig. 5, is locked when in the down position by a known arrangement comprising pivoted hooks 30 which may be released by backing the tractor so that a rail 27 thereon butts a plate 31 attached to arms 29 carrying the hooks. In order however to prevent accidental release of the hooks a second locking means 17 counterbalanced by a weight 33, Figs. 1, 2, and 4, is pivoted on the wheel axle 16 and provides arms 18 which in the undercarriage down position prevent the hooks 30 from pivoting out of locking position. A cross-bar 34 on the means 17 is engaged by the rail 27 when coupling so that the arms 18 are pivoted from beneath the hooks just prior to the abutment of the rail with the hook pivoting mechanism 29 and the toggle breaking buffer 25. The means 17 is provided with a spring pressed plunger, Fig. 8, which engages in a recess or recesses 43 in the wheel axle to prevent inadvertent operation of the means from either the operative or inoperative positions. The weights 33 also act as stops to curtail swinging of the locking means.
