PRIMER AND AIR INTAKE ron GAS ENGINES.

To all whom it may concern;

Be it known-thatl, LARKIN J. SKINNER, a citizen o f the United States, residingat F letcher. in the county of Comanche and State of Oklahoma, 'l aveinvented certain new and useful Improvements in Primers andAirInt-akes for Gas Engines, of which the following is a specification.

My invention relates to a combination primer and airinlet for gasoline engines primarily. but not specifically, adapted for use in conjunction; withthe engines of Ford automobiles whereby-a charge of gasoline may be taken into the engine manifold whenever desirable, and the invention being adapted for permitting. a supply of hot air to also enter the manifold while the engine i running for assisting in a thorough vapor ization of gasoline.

A further object of my invention resides in the'provision of a device as is comparatively simple in construction of such a nature as to be expeditiously adapted for application to Ford engines to be held in place by th elements which hold the intake and exhaust pipes in place.

l/Vith the above and other objects in view as the nature of the invention is better understood upon consideration of. the following specification and accompanying drawings the same consists in the combination and arrangement of parts hereinafter more fully described.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a side elevational view with a portion of the motor of a Ford automobile together with my improved primer and air intake;

Fig. 2 is a vertical cross sectional View taken substantially on the line 22 of Figure 1;

Fig. 3 is a fragmentary vertical cross sectional view of the engine intake manifold showing more clearly the type of three-way valve employed in conjunction with my invention; and i Fig. 4 is a transverse cross section of the gasoline storage tank for disclosing more clearly the supporting means therefor.

Referring to the drawings in detail, 5 designates an exhaust manifold of a Ford type motor; 6 the intake manifold; 7 the carburetor; andS the vehicle dash board,

all of these parts being'of well known construction and therefore not" the essence of my invention, the same beingshown so as to more adequately disclose the relation of my invention therewith.

My invention embodies the provision of gasoline supply tank 9 ofanv desirable capacity. the same being rigidly secured upon the said vehicle dash 8 through the instrumentality of a strap 10, the ends of the strap being formedwith brackets 11 as more clearly shown in Figure 4. These'brackets 11 are secured to the dash by any appropriate fastening means 12 such as screws or the like; i i i Positioned upon the exhaust manifold 5 is'what may be termed a hood 13, this hood being rigidly secured upon the manifold through the mediumof the usual clamping arms 14 between the exhaust and intake manifolds. This hood 13 is in the form of a metal plate, the upper end thereof being curved to conform to the curvature of the manifold 5 as more clearly shown in Figure 2. The edges of the hood 13 are flanged inwardly as at 15 whereby the said hood supported in spaced relation to the manifold. a

In the practical application of my device to an automobile engine of the Ford type the manifold 6 is provided with a screwthreaded opening 16 and disposed within this opening is the screw-threaded nipple 17 of a three-way valve 18. As clearly shown in Figure 3, the nipple 17 forms the outletfor this valve while the same is further provided with a pair of inlets 19 and.

20, the same being screw-threaded as shown. Secured to the inlet 20 of this valve 18 through the instrumentality of a coupling 21 at one end of a gasoline feed pipe 22 the same extending upwardly and being in turn secured to an outlet valve 9 of the said gasoline storage tank 9. Secured in a similar manner the other inlet nipple 19 to the said valve 18 is one end of a hot air pipe 23, the same being in direct communication at its opposite end with the said hood 13 upon the intake manifold 5. The valve core 18 carries the usual operating finger piece 2 1 and loosely and pivotally secured to this finger piece 24 is one end of an actuating rod 25, the same extending rearwardly as shown and being engaged through an opening 26 of the dash board 8, the end of this rod being formed in an operating head 27 whereby said rod 25 may berotated.

In view of the above description it will at once be apparent that when the valve core 18' of the valve 18 is in-a position as shown in Figure 3 and the motor is running hot air will be sucked into the manifold 6 assisting in the thorough combustion of the fuel. In starting a motor in cold weather it is desired to inject a charge of gasoline into the manifold, the valve core 18 is turned so as to establish communication between the gasoline feed line 22 and the said outlet nipple 17 of the valve, it being further understood that if it is ever found desirable the valve core may be rotated to sucha position as to permit a partial charge of air together with a small charge of fuel pass into the intake manifold 6.

Although I have'shown and described the preferred embodiment of my invention it is nevertheless to be understoodthat minor changes may be made therein Without departing from the spirit and scope of the in Vention as claimed.

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

An explosive engine starter comprising a tank independent of the tank which is normally employed for supplying liquid fluid to the engine, a valve body applied to the intake manifold of the engine at a point between the point of connection of the said intake, manifold with the carburetor and the branches of the said manifold, a pipe for conducting preheated air from the exterior of the exhaust manifold of the'engine at a point between the ends thereof and connected with valve bodies, a pipe connected with the first mentioned tank and with the saidvalve body, a valve turnably mounted in the valve body and means for turning the valve, the parts being so arranged that the heated air and fuel from the first mentioned tank may be admitted in a mixed condition into the intake manifold and in advance of the mixture which is lead into the said manifold from the said carburetor.

In testimony whereof I afiix my signature.

LARKIN J. SKINNER.
