FRANK E. HENABRAY, Urrea., New YORK.

CAHESUFSETER.;

a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful improvements inv Carbureteis, of which the tollowingr is a specification, reference being had therein to the accompanying drawing.

My invention relates to an im roved carbureter, and l declare that the fo lowing is a full, clear, concise and exact' description thereof suliicient to enable one skilled in the art to make and use the same, reference being had to tlm accompanyingdrawings in which like letters and numerals refer to like parts throughout.

vapon'zer which is commonly used on combustion engines and one of the principal features is the provision of lips ivotally moui'it-V ed under tension which is a justable to control the amount of air admitted to the mixin chamber, and the form of which lips is suc as to insureperfect mixture of the air with the oil. i

' The specification and drawin s disclose one form oi the invention whici includes minor details.

In thedrawings Figure 1 is a cross-section view'of the device showing the oil reservoir and the, mixer with the air tube. Fi 2 is a cross-section view of the mixing cham er and air vtube taken from the side of the device. Fig. 3 is a top plan view of the device and Fig. 4 is a bottom view. Figs. 5 and 6 are detail views of the upper ends ol" the li s. Figs. 7 and 8 are detail views cfa catchwhlch supports the float in the oil chamber.

Referring to the figures more in detail, 1 Yrepresents the oil chamber which it will be understood isprovided with a suitable inlet. In the bottom is mounted a spindle 2 on which is supported the float or cork23. The

chamber 1 is provided with a tube' which carries the oil to a needle valve 4 through which it passes to the tube 5 which carries it to the mixing chamber 6.

The spin Le Z is notched as at 2a in a series of laces so that the cork may be secured in vositions on the spindle. On top of the corkll away internally to present the tongues 8 which are notched as et 9 to engage the spindle 2 and which-tongues are made to have Specicaton of Letters Patent.

resiliency. The outer tips of the clips are turned up as at 10 to provideconvenient means to gras the tips. When the cork is slipped onto t e spindle the tongues 8 spring upward permitting the cork to be slippedo downto its proper osition when the vtongues engage in one of t 1e .notches 2a. The lcork may be.y raised to permit readjustment rol the;V saine by lifting at the ears 10. The surface of the cork under the clip may bey slightly hollowed out if necessaryfasshown by s anting lines in Fig. 1. It will be understood `that the oil receptacle has a suitable top 11. bserving Figs. 2 and 4 it lwillbe seen that- Y the tube 12, intthe upper end of which is theV 7o. .mixing chamber, is not cylindrical but laterally enlarged below a point/about opposite Thel invention relates to' a carbureter or the top of the tube 5. In these lateralflr'e.- cesses are pivotally mounted two li s. 13;] mounted at 14 which are hollowed longitudi# nally, being, roughly s eaking, loniltpdinal sections of a pipe an these are gedly mounted as stated .so as to swing eachrm the center outwardly into the enlarged pnfi; tion oi the pipe l2. This part 12,-it is se'nre is, in plan view-r a horizontally. elongatedf chamber with opposite walls parallel,A along" which'the edges of the lips slrdeuin` more. or;``I less closeness of Contact, as the lips'opfer1'a11d'""y close and it' istherefore unnecessary toflifave- 85 side-walls on the lips to nie/et;forinstance,pi" the medial vertical line off the l'chf'tmbver4 1 when the lips arejclosed since tllejonlyfou ward air-passageis between thefextreniti 'of the lips. Again, the chamberbeingllater ally enlared and the'- lips being of theformf]- shown, (p ane from end tolend) theyjatre er1-.1 tirely out ot" the air-passa e atthe period f" maximum air current an form no obstru tion whatever to the air'currents. 'f The 'a 95 enters the chamber through'openin V llfanrl'fgfpasses up the inner conlvefaces o thelips whereby the re larityof'the'air currents are disturbed and t e'mixing of-theair and vapor in the chamber 6 is insured'. vThe upper ends roo of these lips'come against theupperend ofv pipe 5, as shown in F1 3,V there being reas son of the form of t e lips anvo'pemng be tween them even when'in norm'al'jposition; so i y thaty a minimum amount of fairfis admitted Vroi but always in a' current which iswm'ore'or less f' agitated. `jV

The lips are, asfshowm longitudinal secit tions of pipe and at the upper end terminatej bythe cuttingfgct the pipe transverselylani y..

not by upsetting or Hanging it (as has been done), so that the present Construction provides absolute freedom for the passage ot' nir along the trensverseiy-oncaved surface oi" each lip and out at the end, these trices de fleeting and breaking up the fir-currents by their impinging against the feces since they are generally oblique to the norrniil line et' current, :ind not obstructing or bashing up the air as it passes from the lips but dischin'g ing the current from :1s-eli lip against that from the other. The fuel or vapor pipe is hetween the'lips lying in the saine geneiai direction as the air currents and the lips and et about the center of the chamber 12. The air and the vapor et shout the end of the lips are discharged in the seine geiierel direction in the pipe but in obliquely crossing lines so posing currents, but nach air current strikes against the other. At the point. of discharge the air currents also impingev against the fuel current, the nir and vapor being; thus mixed and more completely eoininingled h r their inipinging against the sloping vffiils ot the chamber 12 where it reduces to the pipe o.

The lips 13 are cut out with their tips in the form shown in Fig. with two strips eK- tending therefrom shown es 13 and s hollow, 13b, therebetween which entends helow the transverse edge of the tip. the tip vi place e leather' shield 1.6, bending` the tips 13 over it and passing the opposite ends of the tips through the. holes 1,3 profv vided in the lips, so that the leather is cured in place and forms n, tend toi' theiips when lbea-ring against the tube .5 and permits them to make a. smaller opening when rinsed. 40 The lower end of the tube 't2 has voire 17 bored to receive horod-srrewI 1R through which is inserted :i heiidedfpin 19. and ii thumb-nut is provided for loretnie theI screw 18 in pltre. ."i spring 21 isprovided. one end of which eonnerts with the heededpin 19 and the other end of which is provided with loops 32. engaging the lips 13, one on each side. Bv ineens of these parts the ten sion oithe sprin r 1 is adjustable torontrol the ploy of the lips 13 to iidinit nir in ,ui-enter or-less quent-ity iii-rordine to the varying ronditions its will he readily iipprerizifed by those familior'uith surh deviens. the purpose. l
