Specification of Letters Patent.

Patented Oct. 2'7, 1914.

Application filed December 18, 1913. Serial No. 807,446.

To all whom it may concern:

Be it known that 1, JOHN C. SKINNER, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Fuel- Heaters; and I do declare the following to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in internal combustion motors and particularly to the fuel supply and intake means thereof, the object of the invention being to produce a heater for the fuel by means of which a low grade fuel may be used with the same degree of efliciency as a higher grade and whereby a very much smaller amount of fuel is required to operate the motor.

Other advantages gained by the use of my improved invention are that the motor may be regulated to operate much more smoothly and cooler and be controlled or throttled down to a greater degree of nicety than is now ordinarily accomplished in this type of motor. v f

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These ob ects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of an explosive motor with my improved heater installed thereon. Fig. 2 is a top lan view of the same. Fig. 3 IS a side elevation of my improved heater. Fig. 4 is a sectional vlew of the same.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the motor which may be of any usual type, and 2, the carbureter thereon, and 3, the manifold intake plpes which are ordinarily connected with the carbureter. My improved heater is installed between and connects with the carbureter and manifold pipes and is constructed and .a flange 15 at each en 1 numeral 9 designates a fuel supply pipe,

which leads into the member 4 where it is coiled around the member 5 and then passes out of said member 4 and connects with the carburetor 2 in the usual manner. The numeral l1 designates a hot water pipe taken from any suitable point on the upper water pipe 12 and projects into the member 5 where it is formed into a pair of inverted conical shaped coils, the said pipe from the lower convolution of the lower coil com-' municating with the member 4, there being I an outlet pipe 14 from the upper end of the member 4 leading back to the connection with the water jacket of the motor or with the radiator as may be desired, whereby with the circulation of the water through the motor, the hottest water will circulate through the pipe 11, coils 13, casing 4, pipe 14 and back to the water supply of the motor. The said casin 4 is provided with whereby it may be suitably bolted to the carbureter on one side and to the manifold pipes on the other side.

When my improved device is installed, as

designated, and the motor is running, there a is a continuous circulation of hot water through the coils 13 and also through'the casing 4 by reason of the connection noted. The fuel passes from the supply tank 10, through the pipe 9, and into the casing 4 where it passes through the coils in the casing, becoming thoroughly warmed by reason of the circulation of the warm water therethrough. After leaving the casing 4, the fuel then passes into the carbureter 2 and with the suction of the engine is drawn from the carbureter through the opening 8 and into and through the member 5. As fuel is drawn through the member 5, the shape of the opening 7 and 8 and the position of the conical coils 13, causes it to be carried directly up through the center of the member 5 thus overcomin its tendency to creep in a film up the si e of the said casing 5. The coils 13 being hot by reason Lani of the circulation of the hot water therethrough, tend to thoroughly heat the fuel as it passes therethrough, thus greatly aiding in its combustion when it reaches the motor.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A fuel heater comprising a casing, a tubular member'spaced within said casing forming an intermediate chamber, said tubular member having an opening at each end, a pipe leading into and through said tubular member and then communicating with said chamber, a pipe leading into and through said chamber and leading thence from said chamber, and means admitting a heating medium to said first named pipe, as described.

2. A fuel heater comprising a casing, a tubular member spaced within said casing and forming an intermediate chamber, a pipe leading into said tubular member and being formed into coils therein and then communicating with said chamber, a pipe leading into such chamber and being formed into coils therein and leading thence from said chamber, and means admitting a heating medium to said first named pipe, as described.

3. A fuel heater comprising a casing, a tubular member spaced Within said casing forming an intermediate chamber, a pipe projecting into said tubular member and being formed in a plurality of conical coils therein and thence communicating with said chamber, another pipe projecting into said chamber and being formed into coils therein and leading thence from said chamber and means admitting a heating medium to said first named pipe, as described.

In testimony whereof I affix my signature in presenceof two witnesses.
