CARL J'. IPSEN, OF JAMESTOWN, NEWYORK.

To all whom t may concern p e Be it known that I, CARL J. Irsniv, a citi zen of the `United States, residing at Jamestown, in the county of Chautauquaand State of New York, have invented new and useful Improvements in Ca-rbureters, of which the following is a specification. y

This invention relates to carbureters, the object in view being to provide a "carbureter which will handle dierent gradesof hydrocarbon oils such as benzin,gasolene, petroleum,` crude` oil and others, the carbureter embodying a construction in which the liquid fuel after being drawn into the body` of the carbureter is forced to; circulate `around a ball-shaped chamberwhich is in direct communication with the explosion orcombustion chamber of the engine, the entrance of the fuel `to `said chamber being` controlled by a valve and the entrance of-` the mixture after circulating around the ball-s`haped chamber being controlled by an automatic `intake valve which admits the mixture `from `the chamber surrounding the ball, the ball being interiorly heated by the rapidly recurring explosions within and adjacent to said ball.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, herein described, illustrated and claimed.

In the accompanying drawings Figure 1 is a vertical diametrical section through a carbureter embodying the present invention.

Fig, 2 is a top plan view of the same.

Fig. 3 is a horizontal section through the carbureter on the line 3-3 of Fig. 1.

Fig. 4 is a section on the line 4-4 of Fig. 1.

Fig. 5 is a section on the line 5--5 of Fig. 1.

Referring to the drawings 1 designates the main body of the improved carbureter, 2 the fuel and air inlet connection thereof and 3 the outlet connection which leads to the combustion chamber of the engine. The outlet connection 3 is preferably formed as an integral part of the body 1, being cast in one piece therewith and is provided with an attaching iange 4 adapted to receive bolts or other elements 5 by which the carbureter is secured directly to an engine, the end of the connection 3 preferably extending beyond the flange i in order that it may be inserted in an opening formed in the head p Specification of Letters Iatent.` Patentgd June 24, 1.919, p Application filed September 28, 1917.

or other part of the cylinder and communieating with the combustion chamber thereof. The inlet connection 2 is preferably formed separately from the body 1 and is flanged as shown at 6 and secured by suitable fastening means to the` body 1. The inlet connection 2 is shown as provided with a lateral air entrance port 7 and is formed at its inner end with a valve seat 8 with which coperates an automatic inlet valve 9 yieldingly held againstits seatbyfmeans of a spring 1() which surrounds the stem 1l of the valve,

the tension of the spring 10 being regulated by means of a nut threaded on the t stem 11. e p f .i y

The inlet connection 2 comprises a plurality of fuel passages 13 and leading to each of said passages is `a separate and independ,- entfuel feed pipe, 141` designating for example a feed pipe for a low grade of oil, l5 another feed pipe` for a `different grade of oil, and 16 a feed pipe for a higher` grade of oil suchasgasolene or benzin. Each of the feed pipes 14, 15 and 16 is controlled by a regulating valve or cock 17 which enables any one of several grades lof fuelto be `fed to the cabureter.

Within the main body 1 of the carbureter "is a combustion chamber 18 preferably of spherical formation, the same being shown as inclosed by a substantially spherical wall 19 illustrated as formed integrally with the body 1 of the carbureter. The wall 9 is in spacedrelation to the body or wall 1 of the carbureter thereby leaving a vaporizing chamber 20. All of the passages 13 intersect the valve seat 8 and therefore when any one of said passages is beingused as an oil Jr'eed passage, it is automatically uncovered by the inlet valve which isunseated bythe suction of the engine and air drawn in through the opening 7 is carried rapidly past the discharge end of said passage 13, taking up the hydrocarbon oil and carrying an explosive mixture into the vaporizing chamber 20.

`The mixture as it enters the inward portion of the vaporizing chamber, is sucked 0r drawn around the wall 19 through an orifice 21 formed through a web or partition 22 which extends at an angle across the upper portion of the chamber 20 and leads the mixture to a valve controlled port or inlet opening 23 in the top of the spherical wall 19. The port or opening 23 is controlled by an automatic intake valve 24C which serves also as the intake Valve of the engine, said valve 24 being` yieldingly held against its seat by means of a spring 25 surrounding the stem 26 of the Valve and adjustable as `to its tension by means of a nut 27 threaded on the stem 26. The stem 26 operates througha guide 28 extending upwardly from a headpiece29 forming the top wall of the chamber 2O and secured thereto by fastening means 30. 31 designates a priming cup controlled by` avalve 32. u 33 designates aspark plug openingwhich vis, located in the bore 34 of thev outlet connection 3 and between the combustion chamber`18 of the carbureter and the ,combustion chamberof the engine.

From the; foregoing description taken in connection with the accompanying drawings-it ,will now be `seen that, due to the suction,v of the engine, air will be drawn through they .connection 2 into the chamber 2O and 4will take up and carry into 'the mixing chamber, liquid fuel passing through the passage 13. In vstarting Athe engine when cold, gasolene, benzin 'orjother highly volatile hydrocarbon oil'may be used, but after the ,wall 19 of the combustion .chamber 1S becomes heatedjbylrepeated explosions, the'higher grade ofi'uel *oil may' be cut oii and the lower grade supplie'dfto the' carbureter, the latter being adjusted accordingly. The mixture is Jforced to impinge against the highly heated 'ball-shaped chamber, iirst. against the lower .part'fthereof then around the upper Vpart thereof by meansoi' the partition or web 22 and is finally ydrawn into the combustion chamber 18. In the compression stroke of the piston of the engine, the valve 24 is automatically closed and at the proper period an explosion takes place at the plug inserted through the opening 33. Thus the bore 34 and the chamber 1S form in eiect extensions or parts 0i the combustion chamber of the engine.

The carbureter has been found effective and reliable in actual use and requires little or no attention as there are no fragile or delicate parts to get out of order and no special adjustment is required. While the carbureter has been designed with special reference to the use thereof in connection with stationary engines, it may of course be used in connection with explosive engines of various kinds.

I claim A carbureter comprising a mainbody inclosing a .mixing chamber, a combustion chamber located within said mixing chamber, an inlet valve controlling the admission of air and fuel to said mixing chamber7 an intake Valve controlling the admission of said mixture to said combustion chamber, yand a mixture deiiecting partition extending across said mixing chamber and serving to direct lthe mixture against, around and over the wall of lsaid combustion chamber before it enters the last named chamber, said partition having an opening through which the mixture is drawn.

In testimony whereof I aiiix my signature.
