ENGINE WITH WATER SPRAY AD10„889, dated May 9th, 1906.-1n addition to the usual exhaust and inlet valves ti and 1), a mechanically-operated valve (E.) is use-d, and bears on a seat provided with a passage (B) communicating with a pressurefed water supply (A), the outlet of water 'being controlled by a needle valve (D). The valve (F.) is timed to open directly
salter explosion, when the water spray issuing from (I( is rapidly converted into steam, and assists the expanding gases so as to increase the power stroke, or the gases of combustion may be compressed by a third inward movement of the piston, in which case the valve (F) opens upon the completion of said stroke, and a second power stroke is caused by the vaporisation .of the water.
COMBUSTION ENGINES. — The -Noiseley Tool and Motor Car Co., Ltd., zand A. A. Remington.—No. 20,342, dated October 9th, 1905--To facilitate the starting of engines, a reservoir (CC is provided above the valves of the engine, for con-taming carburetter' air. The reservoir is fed by a pump cylinder {87) through a nun-return valve (el, the piston (13) being driven from a crank (Dl) on a shaft carrying a second crank (cl), driven by a cylin
der (AL), which is fed with gas from the
reservoir kU The engine proper, consisting partly of the cylinders (El), is supplied with gas by the inlet valves (h) from a common passage communicating with the reservoir, which is supplied at the maximum pressure required for the working of ,the engine. The under sides of all the pistons communicate with the atmosphere by means of a non-return valve (not shownt through the by-pass passages Cr) or )}, so that, at each down stroke of the piston, air is compressed until the ton of the piston passes the upper orifice of the by-pass, and, the exhaust valve (M) opening simultaneously, the cylinder is thoroughly scavenged. When a backfire occurs, the valve (K) is forced back upon its seat, thus preventing ignition of the gas accumulated in the reservoir. The valve (N) of the pump cylinder acts as a safety valve for the reservoir.
BOX SEANNER.—Tutin.—No. 12,688, dated May 31st, 1906,—The head of the box spanner (11) is pivoted to a handle (A) by a pin (C), which passes through an enlargement of the handle ; this construction allows the spanner to be used in
confined places, by using the handle IA) as a lever, as shown in the dotted positions (Al, At), The other end of the handle may he formed into any useful tool, as shown at D.
LIFTING JACK.—Tangyes, Limited, and another.—No. 4,045, dated February 79th, 1906.—The lifting bar (b} of the jack can be raised to the desired height independently of the operating mechanism; this is accomplished by mounting the
worm (I), which is rotated by the removable handle attached to a squared portion ,g), and this allows of the worm being moved out of engagement with the worm wheel (e) when the latter is rotated by the raising of the lifting bar, but is drawn back by the worm wheel when the bar (81 is released, leaving it in position for raising the load. Clso, by drawing the worm out of engagement by hand, the lifting bar 0) is lowered independently of the operating mechanism.
ELECTRIC IGNITION, — Holden. — No. 21,480, dated October 23rd, 1908.— To obviate the necessity of a contact breaker for each cylinder of an internal combustion engine, a single contact breaker (H) is provided, and is rotated from the engine shaft (A) at a speed corresponding to the number of cylinders used, i.e., twice the speed for four cylinders, and three times for six cylinders. A second rotating portion (B) is also driven from the engine shaft, but at half the speed for a four-cylinder engine and so ; this second rotating portion is provided with insulated segments (F) corresponding to the number of cylinders and acting as distributors, thereby necessitating one primary circuit only and ensuring the spark taking place at the exact moment successively in each cylinder.
BRAKE.—Fabrica Ttaliana di Auto, mobili.—No. 13,124, June 6th, 1906.— Surrounding the brake disc (2) are two jaw pieces (3,4) pivoted at 5 and 6 to a stationary member. The other ends of the jaw pieces carry pins (9 and 10), which are opposed to cams (12 and 13) carried ors a shaft (14). Between the pins a spring (11) is mounted, which normally keeps the brake members apart, but, when, the shaft 114) is rocked, the cams force the pins towards each other, and thus apply the brake. The cam (19) is free to slide on the shaft, and is adjusted by locknuts (22, 23), so that the degree of movement of the shaft (141 necessary to apply the brake can be regulated.
