EAR'IMAX. a (ltlZttt ot the l uited States. and a resident ol St. letershurg. in the eountv of Pinellas and State of Florida. have made eertain new and useful lmprovements in Ignition llevii-es t'or lnternahtouihustion lingines. ol' \vhieh the following is a speeilieati u.
My invention relates to improvements in itl'uition deviees for internal e mliu tion en gines. and it eomists in the eonstruetions. eoinhiinitions. and arrangements herein de- 't'l'lllttl and elaimed.

Other ohieetx and advantages will appear in the following speeilieation and the novel features of the devit'e will he partieularlv pointed out in the appended elaiius.
My invention is illu trated in the :lt't'OltP panving drawing forming part of this application in which the ligure is a eentral set"- tion through the deviee. showing its applieation to the cylinder of an internal eomhuation engine.
In Carrying out lll invention I provide a spherical easing having an external wall 1 and an internal wall '3 spared apart from the wall I to provide a water jaeketor an oil vaporizing jacket 3. depending upon the manner in which-the deviee is used. The spherical casing is provided with a threaded extension 4 which is arranged to enter the threaded opening 5 in the cylinder 6. this opening being the one. generally used for insertion of the ordinary spark plug.
The spherieal easing has a laterally ex tending threaded portion T whieh is arranged to receive a spark plug 8 of any suitable t vpe. e vlindrieal eXtenSion f is also threaded to receive a hod v portion 10 of an auxiliarv t'uel intake whieh will he dewrrhed in detail hereiuat'ter.

A portion of the valve stem 1 is threaded to ae ommodate these. nuts.
The auxiliary fuel intake eompriws the lmdv portion l mentioned heretofore to whit-h is serewed a ra ing llltlll ltl' I: having an inlet i This ea ing memher is pro vided with an iuwardlv extending guide memher 'JT having a stem 1H \vhieh hears at it. inner end a valve 29. arranged to engage a valve seat 3 at the end of the memher 10. As will he seen from the drawing the valve stem 2 has an enlarged portit'ii 3t which is provided with radiallv extending openings t leading from the interior of the valve stem. spring 33 is disposed on the interior of the valve *ttlll and hears at one end on a M'reu plug S-l and at the other on a hall valve 2%.). \Ylllt'lt is adapted to ('lo e the hollow stem 2? The outer end of the stem '2 eonnnunieates with a valve easing h: which has a needle \alve 3T arranged to govern an intake port 3. A spring 39 bears at one end on the easing memher i3 and at the opposite end on the adjustable nut 40 \\'lll('ll is provided with a t'ompanion l()('l\' nut 41.
Front the foregoing description of the tit) various parts of the device the operation thereof may be readily understood.
In the drawing 1 have indicated the power expansion area of the cylinder by and the piston by P. Fuel is designed to be introduced into this power expansion chamber A direct from the carbureter. as in engines of theordinary type. This fuel. however. may be of a lower grade than that which is ordinarily necessary. 1t may -be a mixture of gasolene. kerosene. distilled or crude oil. vapor and air. or oxygen in combustible proportions, or it may be a gas such as natural fuel gas or illuminating gas with air and moisture in combustible proportions. or it may be a mixture of any of these combustible combinations overcharged with air and of slow burning temper. \Yhen the latter fuel is used an additionatfuel adjustment may be made by introducing the fuel through the hollow stem tllj.
The auxiliary fuel may be introduced through the inlet 3h, which is regulated by the needle valve 37. This t'uel may be alcohol, gasolene. acetylene gas, or other suitable fuel, either under pressure or gravity feed. Air is designed to enter the inlet so to combine with the fuel in combustible proportions.
Let us assume that the engine takes its intake stroke. This will open the valve 12 against the tension of the spring 122 and will cause a vacuum in the interior of the spherical casing 2 whereupon the valve 29 will become unseated. thus permitting the fuel to pass the ball valve 35 and through the passages 32 where it will con'ibine with the air coming through the inlet :26 and will thus enter the chamber ll as a combustible gas or vapor. On the compression stroke of the engine the fuel already in the explosion chamber A is compressed. .\t the proper time the spark passes between the terminal of the spark plug 6 aml this mixture is exploded. This charge l term the percussion charge, since explosion automatically opens the valve 1; and ignites the gas in the expansion area A. The provision of a combustible gas which is already ignited insures the positive ignition of the gas in the power area A. even though the latter may be of such composition as would not ordinarily ignite by the passage of the electric spark.
It will be understood that the percussion charge opens the valve 12 early in the explosion. That is to say the gas is still burning as it passes into the power area. This not only tends to ignite the gas in the power area by direct contact of the burning gases, but it also increases the compression in the power area and tends to bring it nearer to the point where gas in the power area will ignite under compression alone.
It will be noted that this device acts in fact as an auxiliary carbureter. That is to say. the mixture of the air and fuel of the percussion charge takes place after the valve 25 is opened. this mixture being effected within the chamber ll in which the spark plug 8 is located.
