` Be it known that We, CHARLES B. STJSANG andJoHNl?. STR-ine, citizens of theUnited States, residing .at lLindenvvood, in the y countyof Ogle and State of Illinois, have invented certain new and useful .Improvements in Primers for l-nternal-Gombustion Engines, of which .the following `is-a. specii cation.4 ,v

'l`heobject of this 'invention is to construct a priming means for use when ,starting means to give an added mixture of gasoleney and air to the regular mixture coming from a carbureter, and to so recharge the regular mixture at a point in its passage to the several cylinders, before it is distributed through the manifold sections to said cylinders.

In the accompanying drawings, Figure l shows our improved primer as applied to the engine of a motor vehicle. Fig. 2 is an enlarged vertical section through the intake manifold illustrating the primer distributing head. F ig. 3 is a plan section on the line of Fig. 2.

The embodiment of our improved primer as shown in the drawings, is applied to an internal combustion engine of the multicylinder type and such as are used in motor vehicles, having a dash 5 and radiator 6 located in relation to the engine.

The intake side of the engine is shown With the intake manifold having side Wing sections 7 leading to the several cylinders and a vertical section 8 adapted to lead to a carbureter as is Well understood in the art.

Mounted on the dash 5 is a tank 9 suitable for containing gasolene, kerosene, or such liquid as is to be used in the primin. rlhe outlet from the tank is controlled'by the hand-cock 10, which communicates with a pipe 11 leading to the main section of the intake-manifold, said pipe11 being inclined toward the dash so as to allow gasolene to pass readily to said manifold section, and has '.1 receptacle 12 which retains a certain amount of gasolene. An adjustable air-valve 13 of a common type coinmunicates with the pipe 1l in such a manner as to mix readily with gasolene coming from the tank 9. i

A. distributing head 14 is located Within the main section 8 Aof the intake-manifold, and is supported therein by the connection 15 which also serves as a passage from the ing an internal combustionengine, the prim-` Supply pipe ll to the distrilniting head. The distributing head as illustrated in this case, is of .an elongated cylindrical shape, tapered toward its lower end, is formed with areceptacle 16 :and has a plurality of discharge openings 1T connnunicating With the receptacle l1.6 and discharging at a pointy .ivithin' or adjacent to the divergence of lthe side wing sections 7 of the manifold. Guidepins 18 hold lthe ldistrilmting ,head centrally in themanifold.

When the primer is to be used, that is, when it is'to co-act with the regular intake gas mixture to enable the engine to start immediately responsive to the cranking thereof, the hand-cock l() is opened allowing gasolene to enter receptacle 16. Upon cranking the engine, the suction thereof Will draw the regular mixture of gasolene from the carbureter through the manifold, the mixture passing around the sides of the distributing head, and said relfular mixture will receive an added and commingling charge of gasolene gas at the point of divergence of the manifold sections, said added charge being drawn from the radially spaced opening 17 and comprising a mixn ture of gasolene and air received from the receptacles 16 and l2 and air valve 13. This added charge of fuel gas will enrich and remix with a sui'licient charge of air-,

the charge being drawn to the cylinders from the carbureter so as to put said charge in condition for immediate iiring thus eliminating the defects of the regular initial charges being' insuliiciently and improperly mixed, which causes continued cranking to start the engine and result-s often in the flooding of the cylinders with the charge of fuel in an unmixed state.

We claim as our invention 1. A primer for internal combustion en gines adapted to charge an explosive mixture passing through the main intake section of an engine manifold, with fuel gas, the primer having discharge openings located at points adjacent the r'livergence of said section to several cylinders, said open.- ings adapted to deliver a dischargeat an angle conforming with and in the direction of said divergence.

2. A primer for internal combustionengines comprising a distributing head located Within the main intake section of an engine manifold, the distributing head being a fuel receptacle formed with a, stream charge openings therein, 'a fuel supply tankY having a connection therewith, an auxiliary fuel pocket located 0n said connection between the tank and distributing head, a

valve fer .Controlling the supplyof fuel 'tov ,said distributing head, and an .air Valve 'adapted to Communicate Witn the-distributying head..

4.711 primer for internal combustion engines cmprisinn a receptacle located Within the main seetionof an engine manifold, the receptacle having openings communicating with the manifold, means for admitting fuel to the receptacle, and an air valve comn'iuneating with the receptacle, the air and' fuel adapted t0 be drawn from said receptacle in the forni of a vapor, by the suution of the engine.

In testimony whereof We have hereunto set our hands inpresence of two subseribingbfv Witnesses. l v
