NOZZLE FOR QABBURETEBS.
Specification of Letters Patent.
Patented Sept, is, rare Application filed August 11,1910. Serial No. 576,?05.
have invented a new and useful Improvement in or Relating to Nozzles for Carbureters, ofwhich the following is a specification.
Hitherto hydro-carbons and air, more or less atomized and mixed, used for explosive charges of internal combustion engines, have been supplied to the cylinders generally by the suction of indrawing action of the piston during their cycle of opera tions; but in drawing in suficient petrol (forexamplc) to carburet the air, ,the inlet pipe, or aperture leading to a cylinder had to be throttled or its area restricted. The said throttling to a great extent interferes with proper carburation and in other Ways the rinciple adopted does not lend itself to e 'ciency even in the case of such a highly volatile spirit as petrol. But in using the heavier petroleum with its higher flash point, the olificulties are so greatly increased that it is only adopted for special reasons,
and then provision is made for employing petrol in case of failure with the heavy hydro-carbon.
By my invention I am enabled to use either light or heavy hydro-carbons, or both, with great elliciency and it relates more particu larly to that type'of combined carbureting and vaporizing apparatus in which the mix-- ture of air and volatile liquid issues from the atomizing nozzle in a thoroughly commingled stat The object of my invention is to provide an improved apparatus of the foregoing type which is characterized by the fact that the carbureted and vaporized mixture feed is effected, by the action of air under pres surepassing into a clearance space below lid the 'atomizing nozzle where it becomes thoroughly mixed with. the hydrocarbon.
The accompanying drawing is in illustration of my invention, the figure being a central vertical section of 1 my improved form of jet supply nozzle for internal cornbustion engine carburetors. .t
According to'rny invention t is essential,
first, that the hydro-carbon employed shall be ellectually sprayed and thoroughly mixed with the air entering the mixing chamber, and in order to attain this end I combine an annular air passage a with a hydro-car bon central supply pipe Z). This air passage a is so constructed that when air from a suitable pump or compressor enters through the supply pipe 0 it traverses the helically formed passages d formed in an enlarged portion c at the top of the center supply pipe Z) aforesaid and issues into the clearance space it where it draws up a supply of the hydro-carbon through the supply pipe 5, the latter being immediately broken up and thoroughly mixed with the issuing air before passing through the jet orifice j. f is an internally threaded cap or nozzle conveniently fitted on the top of the main jet or neck portion 9 and it is provided with a clearance space it for mixing and atomizing the jet of hydrocarbon issuing from the pipe 5 through the pin-hole The head 6 is adapted to rest on the end of the threaded neck and to efi'ect communication between the annular passage o and the spiral passage :2 the plug portion 9 is dished at its upper part at g.
W hat I claim as my invention and desire to secure by Letters Patent, is r In a spraying device of the class set forth, a jet body provided with an air passage therein, an externally threaded neck formed 'on said body about the mouth 01 said passage, a nozzle threaded on said neck, a sup 1' lie carried b said bodv and assin .l l U z:
through said passage, an enlarged head formed on said pipe and having spiral grooves on its periphery, said head being adapted to rest on the end of said neclr, the latter being dished at the mouth of said conduit to etlect' communication between being retained. on said body and prevented from dislodgement by said nozzle, as mt forth. 7
, In witness whereof I have hereunto set my hand in the presence of two witnesses.
