FUEL-HEATER FOR EXPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented June 1'7, 1919.

Application filed August 13, 1917. Serial No. 186,068.

To all whom it may concern:

Be it known that I, GEORGE H. HAYES, a citizen of the United States, residin at Hazelton, in the county of Barber and tate of Kansas, have invented a certain new and useful Improvement in F uel-I-Ieaters for Explosive-Engines, of which the following is a specification.

My invention relates to improvements in fuel heaters for explosive engines.

The object of my invention is to provide novel means for supplying heated fuel to an explosive engine, so that the engine may be easily and quickly started in cold weather.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing which illustrates the preferred embodiment of my invention,

Figure 1 is an elevation, partly broken away, of an ordinary carbureter and manifold provided with my improvement.

Fig. 2 is an enlarged vertical sectional view of the fuel container of the heater, a portion of the fuel conductor heated thereby being shown in elevation.

Fig. 3 is a top view of what is shown in gimilar reference characters designate similar parts in the different views.

1 designates an ordinary carbureter which discharges into the intake end of a common manifold such as is employed on explosive engines.

3 designates a liquid fuel conductor having a branch 4 leading to the carbureter and provided with a branch 5 which discharges into the intake portion of the manifold 2.

In the branch 5 is provided a shut-off valve 6.

For heatin the liquid fuel before it enters the carbureter, independently of the engine with which the carbureter may be connected, the branch 5 is provided with a coiled portion 7, preferably located below the manifold 2 and disposedin a fuel container, preferably comprising a cup 8, which is supported by a clip 9 which embraces the branch 5. I

The' upper portion of the side walls of the container-' 8 may be provided with perforations 10 for admitting? air to support combustion of the fuel held within the container.

In the operation of my invention, fuel, such as gasolene, is poured into the container 8 and lighted, after which the shutoff valve 6 is opened, thus permitting fuel to pass through the branch 5 into the manifold 2. The burning fuel in the container 8 heats the coiled portion 7 and the manifold 2, thereby heating the fuel, such as gasolene, which passes through the branch 5 into the manifold. The engine may be readily started with the heated fuel, following which the shut-off valve 6 is closed, and the manifold is thereafter supplied with the explosive mixture which is discharged from the carbureter 1 into the manifold 2.

I do not limit my invention to the structure shoWn and described, as modifications, within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1. A carbureter, a manifold connected therewith, a liquid fuel conductor having two branches respectively discharging into the carbureter and into the manifold, a shutoff valve in the branch leading to the manifold, and means independent of an engine to which the carbureter may be connected for heatin the branch which leads to the manifold.

2. A carbureter, a manifold connected therewith, a liquid fuel conductor having tWo branches respectively discharging into the carbureter and into the manifold, a shut-off valve in the branch connected with the manifold, and a fuel container located so that heat from burning fuel contained therein will heat the branch leading to the manifold.

3. A carbureter, a manifold connected therewith, a liquid fuel conductor having two branches respectively discharging into the carbureter and into the manifold, a shutoff valve in the branch connected with the manifold, the branch connected with the manifold having a coiled portion, and a container for liquid fuel in which said coiled portion is located.

4. A carbureter, a manifold connected therewith, a container adapted: to holdburn 5. A carbureter, a manifold connected therewith, aliquid fuel conductorhavingtwo branches respectively discharging into the carbureter and into the manifold; the branch connected with the manifold being provided with a shut-01f valve and having a coiled portion, and a container for liquid fuel hav- 10 ing an open top and encircling said coiled portion.

In testimony whereof I: have signed my name to this specification.

GEORGE H. HAYES.
