APPARATUS FOR TIE-IE GENERATION OF COMBUSTIBLE GAS OR VAPOR FROM LIQUID FUEL.

Patented J uly20, 1915.

Application filed December 13, 1912. Serial Nb. 736,521.

To all whom it may concern Be it known that. I. FRANK GUY LANG Binmaacoamn, a subject of the King of Great Britain, and a resident of Luton, England. (whose post-oflice address is 29 Kenilworth road, Luton, in the county of Bedford, England.) have invented Improvements Relating to Apparatus for the Generation of Combustible Gas or Vapor from Liquid Fuel.

This invention relates to an apparatus for the generation of a combustible gas or vapor from heavy liquid hydrocarbon fuels such as paratlin that cannot be so readily vaporized as petrol or other of the lighter hydrocarbons.

The gas produced may be used for motive power purposes of many kinds and the apparatus.hereinafter called a generator-is modified according to the purpose for which the gas is to be used.

My device broadly speaking is as fol- 1 lows:Fuel in a liquid stateeither in the form of a stream or of coarse drops-is supplied to the generator simultaneously with a quantity of ;.ir sufficient to burn completely part of the fuel, the fuel is heated and vaporized, and a port-ion of the fuel is burnt by the aid of the air. all of which is used. while the remainder of the fuel. passing in an unburnt condition through this burning region. is thereby changed into a gasor vapor or mixture of both, which is employed for motive power purposes.

l .ceording to the present invention, the operation and control of my in vent-ion in its different stages, is accomplished by applying suction to one end of the generator. this serving to draw off the combustible gas pro duced. and to draw into the generator the fuel and the necessary supply of air, the fuel being drawn in through a nozzle and the air through a suitable part or parts.

The invention is especially applicable for use on motor vehicles. the suction then being provided by the induction stroke of the motor.

i The apparatus as adapted for use on motor cars is comparable in action and eflicieney with the jet carburetors for petrol.

In the accompanying drawings Figure 1 shows in vertical section a form of the invention. suitable for use on the internal combustion engines of motor cars.- Fig. 2 is an closed by a shallow tray 4. This inlet 3 communicates with a connection-box 5 into which a tube 6 from a float chamber 7 projects. the float in the latter automatically controlling the supply from the main oil tank. as in the well-known float-feed carbureter. A limited supply of air is also admitted into the box 5 through a perforated plug 8, described more fully hereafter. lVithin the 'shell 1 is an open hollow cylinder 9 situated so as to leave a space 10 between it and the shell 1. The lower end of the shell 1 is enlarged in diameter and then folded inwardly upon itself in the form of a thick flange 11 of special shape. as hereinafter specified. The bottom 12 of the cylinder 9 does not touch the flange v11; its upper end is contracted at 13 and protrudes hrough the roof of the chamber 2,

into a hollow top piece 1% fitted with a flange 15 suitable for connecting directly or indirectly to the engine cylinder. The shallow tray t above mentioned is suspended by a.- rod 16 which extends upward throughout the combined length of the shell 1 and piece 14, and, projecting through a gland or suitable opening in the latter, is provided externally with an eccentric 17, having a linger 18. by which the rod 16 may be raised or lowered. The effect of lowering the latter is to lower the tray 4, until there is an air space between the edge of the tray and the open bottom .or flange 11 of the shell 1. When raised again, the tray closes up against the flange 11. The lower end of the rod 16 preferably carries a nut 19, above which is a spring 20. both of these being underneath the tray 4.

The external wall of the cylinder 9 is formed with an open spiral 21 serving as a. conduit for allowing the oil or mixture of oil and air to travel over a large area of the wall before reaching the bottom. The upper extremity of this spiral 21..is surrounded by a band 22 Which prevents any air, vapor orv spray from passing down below excepting along this portion of the spiraL ficiontly soaked,
