Application filed July 30, 1914. Serial Nb. 854,033.

To ali whom 'it may concern.

i lle it known that l, Eposn ScHNniDnn, of Le Crenzot. France, have invented a neu and useful improvement in or Relating to Autoindbile Torpedoes. which is fully set icorth infthe following specification.

This invention relates to automobile torpedoes of the kind in which the compressed air that drives the propelling engine is hented prior .to its admission to the engine. l4` this purpose the apparatus i'or heating the compressed air has `as is shown diagrammetically in Figure l of the acconnianyinn drawing, comprised .u combustion chamber 1 arranged between the compressed an' reservoir 2 and the engine 3. The air coming from .the reservoir 2 passes by pipe 9 to the inlet port of valve A .from which it leeres through conduit I0 and passes through pipe 6, forcing liquid hydrocarbon and water from the reservoirs 4 and 5 into the chamber 1 thiough the pipes 7 and 8 respectively. A;-coxidi'iit` 1 1 supplies-the combustion chamber. twith compressed air. .Upon these pipes, cocks are generally fitted and these cocks 4are opened before placing the torpedo in the launehing'tube. Now between the mo- :nentat which the said cocks areopened and the'time of launching the torpedo which coincides with `the vactuation of the startinglever L'nnd the opening oi'the air inlet., a considerable period of time elapses. Dui-ingrJ thisfinteltvnl of time, the pipes 7 and 8, the :chamber l andethe pipe which connects the latter with .the engine become filled -with combustible vapors. The result is that in` opportune explosions often take place.

The chief object of the .present Vinvention is toa-neidthe possibility of explosions occurring Whenthe ignition vot the heating A cartridge in the combustion chamber takes place, Vand r,to prevent faulty ignition and Y mis'ireswhich sometimes take place if the.

pressure in the said chamber varies suddenly.

I are actuated by the usual balance lever B the movements of which are produced by the movements ofthe starting lever L.

K is the usual reduced admission valve 5 which is lifted as soon as the lever L is shifted into the position L by the intermediary of a lever Q and of a rod Q. The balance lever B actuates through a pin B2 a clutch member C of a known stopping mechanism,

the companion member C of which is adapted to be rotated by the motor and is subjected to the action of a spring R.

Czvis an indeX Enger. The balance lever B is connected by a rod B with one arm of starting lever L which controls the reduced admission Valve K through a connection `I designates a member which moves with the balance lever B and which is guided in bearings J, J rigid with casing A. A

spring 1' bearing at one end upon a ring M fixed in the member I and at the other end upon a fixed stop formed by the bearing J, constantly lends to return the member I to 'the position represented in Fig. 2. In a casing E, which maybe integral withl casing A', a clutch member F is capable of rotating. 'lhe other clutch member H is provided with a tail piece carrying at its upper extremity an indicating hand H', which is displaceable over a graduated dial H2, by means of a stop not shown on ring H4. Around the rod carrying the clutch member H a torsion spring 2 is coiled; one end of this spring is fixed to the member H and the other to a ring H* pressed into the dial H2 by a powerful spring H5. The member F is provided externally with teeth by means of which it gears with a pinion F keyed to a Shaft G driven by the engine. A washer or ing an elongated hole O (Fig. 3). A pin R carried by an arm T integral with the cock T engages in the hole O.

The operation is as follows. At the moment at vwhich the lever L of the starting valve is broughtrearward, to L', the engine starts at low speed with cold air, owing to the fact that the valve K and the member VI are only lifted to the extent necessary for throwing-in the clutch H-F, this travel be-1 ing insuiiicientto. open the valve A-a and rotate the cock T. The cock T therefore remains closed so that the water and the liquid hydrocarbon do not reach the 'combustion chamber.

. When at the end of a predetermined number of revolutions of the engine the member I enga es in an orifice L in the clutch element the 'clutch F-H is thrown out of operation and the full admission valve A-a then opens fully and the engine commences to run at its normal speed. At the same time the member I in rising opens the cock 'I by the intermediary of the collar M, the lever O and the arm T', and the water and the liquid hydrocarbon then reach the combustion chamber, to enable the heating of the air to commence. It will of course be understood that the ignition cartridge is so arranged that its firing does not take place until the end of the low speed running when the valve A-a opens fully. Vith this object the firing may be controlled by a device connected with the push rod b or with the member I.

At the moment at which the torpedo stops, the member I is returned by the balance lever B to its initial position; the spring 7 then causes the collar M to descend and close the cock T. Consequently the liquid hydrocarbon and the water cease to flow to the combustionchamber. It is therefore easy by measuring the amount of liquid hydrocarbon and water remaining in their containers after the run of the torpedo to exactly ascertain the quantity consumed during the run.

In an automobile torpedo, the combination of an engine, a source of compressed air, and a source of liquid fuel, valve controlled conduits connecting the engine with said sources, means for opening said air valve to start and scavenge the engine and means controlled by a predetermined number of revolutions of the engine for timing the opening of the fuel valve after the engine is scavenged.
