To all whom it may concern:

Be it lrnown that I, ROY M. Tnivorgn,

citizen of the United States, residing at,

Denver, in the county o flDenver. and State oi Colorado, haveinvented certain new and useful Improvements in Carburetors, "of

. which the following is a specification.

" drawings.

The present invention relates to improvei ments in carburetors, the object beingto'pr'ovide simple and effective means fortsecuring a more complete 'intermingling' of j the liquid fuel and'a'ir to effect a'morecom plete and thorough atomization" of the former; A further and important izobject is to provide a device that can' be inade and sold as an article of manufacture, and can be placed in a carburetor"without altering the structural features thereofbeyondyre moving the device forrwhich it is" substituted."

f The preferredlernbodiment or the levee I 'tion is illustrated in the accompanying drawings, wherein r Figure 1 is a vertical sectionalf-view through a. carburetorpsho'wingthe device in place. l i

Figures 2 andB are cross sectional views on the lines 22 and 3-3' oil-Figure 7 Similar reference: numerals designate corresponding parts 'in'all the figures of the 'The carburetor disclosed comprises a suitable shell 4 having an internal chamber 5 closed by a removable cap 6. 1 The shell has an air inlet 7 on one sidethatcommunicates,

as shown at 8,' with the lower .portion of the chamber wall. An outlet 9, opening through the opposite side of the shell, has fconr munication at'10 with the upper portion;

of the chamber 5'. The outlet is cont-rolled bya suitable butterfly valve 1LJ The shell is furthermore provided below the chamber 5 with a depending extension 12 havi a Mil bore 13 in which isiplaced a spray nozzle 14 which has its upper ens provided with a flange 15 that rest upon the bottom 16 01 the chamber 5. This nozzle has its dis charge orifice 17 delivering centrally and upwardly into the chamber5. The said orifice is controlled by a needle valve 18, the stem 19 of which is threaded through the cover 6. Surrounding the extension '12 is a supply reservoir 20 that has communication Withthe lower portion of the nozzle 1% through a port 21.

With this "construction, it will be evident that twostrata of air are drawn into the" and thorough atomizachoke sleeve in aj'tangeritial direction at different points, and'will be caused to whirl within thesame. Experience, has demonstrated that this action evidently results in a more complete and thorough atomization ofthe liquid fuel projected upwardly from amount of initial fuel. The deviceobviously can be either made as aniinitial ele- 23 remains stationary after the bottom spray nozzle, thereby insuring a better explosive, mixture with a smaller ment in the construction of the carburetors or where other choke devices are employed, they may be removed and the present device without further description, and it, will be understood that variousgchanges in the size, r shape, proportion and minor details of construction, may be .res ortedfto, within, the
