GAS-SAVING DEVICE FOR ENGINES.

Specification of Letters Patent.

Application filed December 14, 1914.

To (all whom it may concern Be it known that I, FRANK YnoMAN, a citizen of the United States, residing at Ormille, in the county of Butte and State of California, have invented certain new and iiscful IITIPIOVGITIGDtS in Gas-Saving Devices for Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

The present invention relates to improve ments in in nal. combustion engines and it is especially designed for use in connection I, with gasolene motors of auto vehicles.

One obgoct of this invention is to pro-- videan auxiliary attachment by means of which heated apor may be conveyed from the radiator to the intake manifold to augment the ellicacy oil the combustion .nixture and increase the engines efiiciency.

Another and. further object of this inventionresides in providing a means by the utilization o1 which the engine cylinders may be more or less cooled and the spark plugs maintained in a condition free from carbon particles.

Another and still further object of this invention is to provide a novelly constructed -valve for controlling the supply of heated vapor to the intake manifold.

A final object of the invention resides in providing a means located on the steering post in convenient reach of the operator for manipulating the valve.

With these and other ob'ects in view mv invention consists of certain novel details of construction, combination and arrange; ment of parts to be more particularl .pointed out and claimed.

in the accompanying drawings: Figure 1 is a. diagran'n'natio view illustrating the device operatively applied to a motor vehicle; Fig. 2 is an enlarged transverse vertical section of theupper portion of a radiator, illustrating, the disposition of the steam outlet pipe and showing a fragment of a flexible tube connected to saidpipe. Fig. 3 is a side elevation of the-valve housin tu es attached thereto, together with a portion of the valve stem and operating rod connected therewith, and'Fig 4 is a trans verse vertical section certain parts being shown in elevation.

Briefly stated, my invention consists of illustrating fragments of the flexible Patented Apr. 25, 1916.

Serial No. 877,258.

a connection between the upper portion of.

the radiator and the intake manifold of the gas engine, and a valve arranged in the length of said connection for controlling the passage of steam through the latter to the intake manifold, together with means for manually operating the valve, as Will be readily understood. Y

Inconnection with the steering post 1 having the usual steering wheel 2, I employ a'T- shaped valve housing or casing 3 which is secured by" suitable brackets #1 to the lower extremity of the steering post 1, as clearly shown in Fig. 1 The casing ii has a later-- ally extending integrally formed. tubular extension or shank 5 externally threaded contiguous to its inner end as at 6 to receive the annular coupling member -7 connected to the inner end of the flexible tube 8. The extension 5 is formed with ailongitudinally extending channcl 10 whose inner end communicates with the interior of housing 3, as clearly shown in Fig. 4. De pending from. the lower extremity of the housing 3 is another integrally formed extension 10 threaded as at 11 to receive the annular coupling member 12 of the flexible tube 13. Extending longitudinally through the extension 10 is a channel 14 having its inner end communicatingwith the interior of. the housing 3 for a purpose to be hereinafter explained.

Rotatably mounted Within the casing or housing 3 is an annular valve 15 having therein the passage 16 adapted, upon suitable rotation of the valve 15, to establishopen end of the housing 3, as clearly shown in Fig.

A valve manipulating rod 19 has its lower .end pivotally connected to the stem 16' of 'valve 15 and its upper end provided with an operating handle 20. This operating rod 19 extends longitudinally of the steering I post 1' to which it is secured byfla suitable D In this connection it is to be noted that the handle 20 ,is disposed im bracket 21'.

: mediately below the steering heel 2 so that it may be Within convenient -operator at all. times.

Projecting through an opening 22 in the upper portion of the radiator"23 is reach of the s formed a steam outlet pipe 24: which extends into the water jacket 25 and passes upwardly through the latter into the annular chamber formed by the externally threaded flange 2(i'surrounding the water orifice in jacket 25. As it would be impractical to have any Water enter pipe 24:, as the radiator is being filled, said pipe has its upper end downwardly curved as at 26. The usual cap 26" is threaded on flange 26 and closes the orifice in water jacket 25. That portion of the outlet pipe projecting from the rear of the radiator is suitably connected to the free end of flexible tube 13 so that the steam rising from the water in the radiator may be conveyed 'from the latter through pipe 2'2, and thence through the flexible tube 13 to the valve housing 3 from whence it may pass in a manner hereinafter to be described, to the intake manifold "27 of the gas engine 28.

Formed in the intake manifold 28 immediately above the carbureter connection is an annular opening 29 into which projects a short pipe 30. To the free end of pipe 30 is connected the free end of the flexible tube 8. By this structure it will become obvious that when valve.15 has been rotated to establish connection between the channels 10 and 14 formed in the extensions 5 and 10 of the housing 3, the steam taken from water tank may be conveyed to the intake manifold from whence it may be passed to the various engine cylinders as will be read ily understood without further description.

From the foregoing description it will be seen that Whenever desirable, the steam rising from the radiator may be taken from the latter and conveyed to the intake inanifold of the engine so that any globules of liquid fuel in the mixture in the manifold may be broken up and vaporized by the steam, which consequently greatly increases the eifectlveness of the mixture and hence reduces fuel consumption. It will also be apparent that when steam is drawn into the cylinder it will remove carbon particles from the spark plug projecting therein. By an attachment which may be readily connected that l have described certain features which may be best adapted to perform the functions allotted to them, nevertheless, I do'not wish to be limited to details other than specified in the appended claim.

I claim: i

In a device of the character described, the combination with a radiator, a steering post, an intake manifold of a gasolene engine, of a T-shaped valve casing-having its head positioned parallel to the lower portion of said steering post, a pair of brackets on the said lower portion of the steering post and a third bracket adjacent its upper end, a rotatable cylindrical valve centrally arranged in the head of said casing, a stem on said valve extending through the upper end of the casing, means to secure said valve in the casing, a rotatable operating rod having an operating lever on its upper end, positioned parallel with the steering post and connected with the valve stem at its lower end, a flexible tubular connection between the upper portion of said radiator, and the lower end of the head of the casing, and a second flexible tubular connection between the end of the shank of said T-shaped casing and the intake manifold.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FRANK YEOMAN.
