CABBURETER.

Patenten Nov. is, asia.

T o all whom 'it may concern:

Beit known that I, JOHN H. Koon'rz; a Y citizen of the United States, residing at Culver in the county of Marshall and State of Indiana, have invented certain new and useful Im rovements in Carbureters, of which t-he follbwing is a specification. Y

My invention relates to carbureters and especially to that class in which the adequate mixture of the gases employed for internal combustion engines, is accomplished largely by the action of agitating mechanism. n

The chief objects of this invention are to produce a simple and effective mechanism for thoroughly commingling the gases preliminary to igintion; to provide rota elements that will have unusual eiiiciency 1n the production of numerous eddies and cross currents in the tiuids presented to their action; and to furnish improved bearings and supports for the moving parts so that their speed and etliciency will be augmented with the expenditure of a minimum amount of energy.

Further objects are secured by arranging automatic means for controlling one ofthe valves, and manually controlled means for operating the supply valves simultaneously. Improved forms of gyrating mechanism and current deectors are disclosed, and the appliance having few parts will not be liable to get out of order and can be economically manufactured. v

I accomplish the above and other im ortant objects by the apparatus illustrate in the accompanying drawing which forms a part of this specification and in Which-- Figure 1 1s aside elevation'of myvim-l proved rotary carbureter; Fig. 2 is a vertical llongitudinal section; Fig. 3 is a verticalf transverse section with some of the parts removed; Fig. 4 is a plan view of the fan shaft bearing ring; and Fig. 5 is a fragmentary view showing the throat v-alve in position.

Referring to the drawing in detail, the numeral 6 indicates the body portion of a tubular casing having its end portions 7 8, curved in opposite directions. The interior of said casing, and more particularly that art inclosed by the body shell, forms'a mixmg chamber 9. The airto be utilized as an ingredient enters the chamber through the inlet 10 of the lower curved branch 7,' its indow being regulated b a valve 11 consisting of a circular plate 12 ormedintegral with a spindle 13 which has its ends 14, 15. reduced in size and-journaled in bearings 16 extending laterally from the casing walls. The plate 12 has a diameter approximating that of the throat of the caslng and when the valve is in its closed position it willl shut ofi' I practically all of the air supply.

The hydrocarbon fuel is introduced into the m'ixin chamber through azpipel which has the e castintegral with the lower section casing. This T` consists of a horizontal body portion 18 from which -projects vertically a branch 19 disposed axially in said mixing chamber. The body has a central bore 20 which communicates with aduct 2l in the branch' 19, and is supplied With an inlet pipe 22. At the point of junction of the lbore 20 with the duct 21 is a valve-seat 23, for a needle supply valve 24, which iits an enlargement 25 in the bore, its free end 24,3L projecting from the end of the body 18'of the T through a stuffing box 26'which is closed by a gland 27 having threads 28 to tit external threads on the end 'of `the tee body. The` upper end of the duct 21 is furnished with a valve vseat 2,9 for an inlet orm of a T 17 and preferably valve 30, which has a stem 31 reduced 'in size to form a shoulder' 32 on whichA is located a circular disk valve 33 of thin metal which is secured in position against the shoulder 32 bya nut 34. This valve disk has a diameter slightly less thanv the bore of the casing at that plane, thus leaving an annular space around the peri hery of the disk. The Valve 30 has a nee le point which rests by gravity upon its valve seat 29 in the extension 19 and the upper end of itsy i stem` is received into thesocket 36 of a guide 37 which is suspended in the axis ofl the casing by arms 38 extending radially in- Ward from a deflecting ring 39 which is cast v integral with thev lower section of the casing. The said ring has a thickened upper margin 41 inclined on its upper aspect to- Ward the inner edge, the inner face 42 of the ring being somewhat contracted from below.

upward. Above said ring is a bearing wheel 43, its rim 44 being triangular in cross section and having radial arms which support a hub 45, in which is formed a ball race 46.

IIn the upper side of the curved end 8 of the'casing 1s a sleeve 47 preferably cast with the casing and projecting downward inthe axis of the casing and having internal threads 48 cut therein. A screw 49 is inioo serted in the sleeve and is provided at its lower end with a ball -race 50. The screw can be adj usted longitudinally and when set 'is held rmlyby a winged lock nut 51.

In the upper end of the guide 37 is also formed a-ball race 52.

Between the bearing wheel 43 and said adjusting screw 49'is located a wheel consist- .ing of a shaft 53 having conical end bearings 54 supported by hardened balls y55, located 1n the sald races 46 and 50. Upon this shaft j is fixed a fan 56 which has suitably inclined blades 57, their outer ends being recurved to "form peripheral volutes 58. Below the bearing wheel 43 is arranged a similar fan 59, its shaft 60 being journaled in fthe bearings 46 and 52 supplied with balls 55.v The wings l57 are recurvedin the same manner at the "free ends as in the fan 56 above described,

the only differ/ence being in the inclination of the wings and the direction of the curvature which are opposite in alternate wheels.

l The pressure upon the balls in the races of the shaft bearings may be varied by turning the said screw 49 until the proper adjust- 'ment is secured, thus reducing the frictional resistance to the rotary movement of the y v fans toa minimum. 1

upon the said'spindle.

.Upon 'theprojecting end 15 of the air supply valve s indle 13 is-mounted a control lever. 60 wh1ch is provided with an arm 60a furnished with a slot 61 connected by a slit 62 with the hole through which the end of the' spindle passes, and an adjustin screw 63 serves to clam the lever rmly link arm 64 provided with a slot 65 has a set screw 66 which secures the link to the projecting end l24a of the needle valve 24. At the opposite end is a shouldered screwl 67 which is fixed in the lend of the said arm 60 and isy adapted to slide in the slot 65 in the link arm.

It will be evidentv that va movement ofthe control lever will operate simultaneously the vair-supply valve 11 "and the hydrocarbon supply valve24, and when the said valves are.4 properly adjusted the coaction of the two" valves thus linked together will insure theintroduction of the proper `pro ortion of air'when there is an increase or diminution in the full liquid fuel.

It ,will vbe .seen that the conformation of the parts within lthe casing will break up 'set i in presence of two witnesses.v

the entering stream of commingled`- 'ases into innumerable counter currents, e dies andiwhirls. -An especial feature being the oppositely gyrating movements of the fans which are automatically rotated by the ac? tion of the air current-s impinging `upon their-wings, the sensitive ball-bearings permitting a comparatively'lvln'derate volume of iiowing gas tok produce a high ratepof speed.

It will be noticed disk valve 33 presents 'a large area to the 'incoming stream and as'the impact upon the. under surface.

of said valve lncreases -itfwill rise higher unseating its needle point v'to a greater ex-V tent and allowing a larger Proportional quantity of the liquid fuel to enter the chamber. Conversely when the control lever is operated to shut oif the supply there will be less force on the said disk ,valvev and its point will become partially or wholly rehaving' their blades oppositely inclined and the eri heral margins of the blades eX- .tending mwardly .and inclined toward `the center of the passageway.

2. A uid mixing device, comprising a c f -lindrical casing, a plurality. of fanfwhee,

each of said wheels having its blades op ositely inclined and the ends of said bla es bent inwardly and inclined relatively to the walls of the casing, land anti-frictional bear# in s for said wheels.
