Specification of Letters Patent.-

Patented Dec. 2, 1913.

Application filed February 20,1912 Serial No. 678,793.

To all whom it may concern:

Be it known that I, VVILLIAM'L. CoRsoN, a citizen of Great Britain, residing in the city and county of San Frahcisco and State of California, have invented certain new and useful Improvements in Gasifiers for Liquid Fuels, of which the following is a specification. l

The hereinafter described invention relates to new and useful improvements in apparatusfor gasifyi-ng distillates or other-low grades of liquid fuels so that they may be employed for successfully operating internal combustion engines and dispenses with the use of gasolene as an internal combustion engine fuel, except for'starting purposes, and has for its principal object to providean inlet manifold with a chamber in which the liquid is gasified before it passes into the engine cylinders, and to surround this inlet chamber with apassage or duct through which the exhaust gases from the engine cylinders circulate, before they are directed to the atmosphere.

Another object is to provide a valve between the exhaust pipe and the inlet mamfold for varying the flow of exhaust gases therefrom and into the passage or duct surrounding the inlet chamber, according to the density of the explosive fuel'employed so that the inlet manifold will always be maintained at the proper temperature to thoroughly gasify the fuel passing through the chamber therein.

With the above mentioned and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings forming a part of this invention, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing fromthe spirit'or sacrificing any of the advantagesof the invention.

To fully comprehend the invention, reference should be had to the accompanying sheets of drawings illustrating a complete constructed device for successfully carrying out the invention wherein Figure 1 is a plan view of my device disclosing the exhaust pipe, the inlet manifold,

the valve controlled communication between gasifying chamber in the inlet manifold, and the passage for the exhaust gases around the gasifying chamber being shown 'in my device, disclosing the inlet manifold, the

chamber-and the segment for controlling the position of the valve cont-rolling the communication between the exhaust pipe and inletmanifold. Fig. 3 is a sectional view of disclosing the gasifying chamber, thepassa'ge or duct for the exhaust gases around ithe same,- and the heating pins projecting 1 from the walls of the exhaust gas passage into the gasifying chamber; Fig. 4 is a disclosing the gasifying chamber, the passage or duct for the exhaust gases surroundingthe same, the heating pins projecting from the walls of the exhaust gas passage and extending into the gasifying chamber, the direction of the passage of the exhaust gases being shown by arrows.

Referring more particularly to the drawings, the reference numeral 1 designates my improved inlet manifold, preferably cast in a single piece, from 'any'suitable material, and preferably oblong in shape. The interior of said manifold is providedin its center' with a gasifying chamber 2, closed at each end of the manifold, thus dividing the manifold longitudinally into three compartments. The chamber 2 is provided at its top with suitable flanged outlet openings 3, one of which is connected to each cylinder inlet opening, and at its bottom with a hollow chamber 4, provided at one side'with a flanged opening 5, which communicates with a source of fluid supply, thus it will be 0b- 1 served that the fuel to be used in operating the engine is taken in through the opening -5 and passes upwardly in the chamber 2 en- 5 te'ring the engine cylinders through the openings 3. The chamber 2 is also provided 2 and 2 which extend respectively from the side walls of the chamber, and are arranged in staggered relation to each other.

manifold 1 and arranged one on each side of 5 and 6, which are open at each end of the dotted lines. Fig. 2 is a side elevation of.

Extending longitudinally. of the inletv the chamber 2 are separate passages or ductsthe exhaust pipe and the inlet manifold; the I inlet and outlet openings for the gasifying the inlet manifold taken on line 33, Fig. 2,

horizontal sectional view of my improved inlet manifold, taken on 'line M, Fig. 2,

with transversely projecting pins or bafiies manifold, they communicating with each other through a channel 7 on the interior of a cap 8 secured over the outer end 8 of the inlet manifold. The opposite ends of the passages or ducts 5 and 6 communicate re spectively with passages 5 and 6, which extend longitudinally of and are arranged within a suitable pipe 9, the other end of said passages 5 and 6 communicate with an exhaust pipe 10 of the engine, through suitable spaced ports 5 and 6 arranged in one side thereof. The exhaust pipe -l0 is of the usual construction and is provided in its center and in a line between the ports 5 and 6 with a butterfly valve 11, said valve being of the .same diameter as the inside diameter of the pipe 10, and secured at its center to a shaft 12 which extends therethrough, one end of which is pivotally mounted in a suitable seat 13 on the interior of the pipe, and the other end of said shaft extends outwardly through a suitable opening 14 in the exhaust pipe, and is bent at right angles to the shaft 12, forming an operating handle 15. The handle15 is adapted to be engaged throughout its path of movement by suitable notches or teeth 16, arranged on the surface of a segment 17, the ends of which are preferably attached to the

pipes

9 and 10.

It will be observed that the valve 11 is mounted to turn in said exhaust pipe 10 and direct the flow of exhaust gases therefrom through the port 5 into the passage 5 of the pipe 9, and into passage or duct 5, in one side of the inlet manifold, the gases circulating through the channel 7 and passing from the manifold into the exhaust pipe 10 in the rear of the valve by the passages 6, 6 and 6 The exhaust gases in their. flow through the passages in the inlet manifold will cause the walls thereof and the pins 2' and 2 to become heated to a very high degree of temperature, so that as the fluid is drawn into the gasifying chamber 2 it en'- counters the staggered pins2 and 2 which have become highly heated, and is quickly vaporized by the intense heat therefrom, entering the engine cylinders in a state of high temperature.

' 5 and 6, when'desired.

Any suitable means or fuel may be used for starting the engine, but the following is preferred.

The engine may be started by any highly combustible fuel, such as gasolene, the exhaust gases therefrom directed around the gasifying chamber, and after the chamber I Having thus fully described my invent-ion what'is claimed as new and desired to be protected by Letters Patent is 1. In a gasifying device for liquid fuels, .the combination of an outer casing having longitudinally extending partitions forming an intermediate gasifying chamber, and 0ppositely disposed heating chambers, the heating chambers communicating with one another at one end, and one of said heating chambers constituting at its opposite end an inlet, and the other heating chamber constituting at its opposite end an outlet, said inlet and outlet being adapted for connection with the exhaust pipe ofan internal combustion engine, one of the exposed sides of the gasifying chamber having intermediate its ends an inlet opening for the fluid supply and the opposite exposed side of the gasifying chamber having an opening for communication with the engine cylinder.
