CARBURETER.

Specification of Letters Patent.

Patented Jan. 30, 1912.

Application filed April 26, 1909. Serial No. 492,298.

To all whom it may concern:

Be t known that I, lVILLIAM J. STEIN- BRENNER, a citizen of the United States, and

resident of 'lluttalo, in the county of Erie and State of New York, have invented certain new and uset'iil Improvements in Carhureters, of which the following is a specification.

My invention relates to in'ip'rovements in carbureters and more particularly to that type of carlmreters designed for use in connection with internal conihustion-engines.

'lhe ohject o'l my invention is to provide a simple and inexpensive carhureter wherein the various speeds for which carhureters are generally arranged may he obtained hy the manipulation of a #ingl element.

it also has tor its Ulljlt'l, the provision of a plurality ot :opiratlug-nozzles having their exit ends arranged in dilt'erent horizontal planeand m disposed with reference to the controlling-valve that the latter, when actuated, serves to ause an aspirating effect, first upon one nrnzzhrand thcn upon another.

'ith these and other objects in View, the invention consists in the relative arrangement of the aspiratlug-nozzles and the eontrollingwalve; and it also consists in the construction, arrangement and comhination of parts to he hereinafter described and particularly.pointed out in the appended claims.

Figure l is a uertical section of a can hureter embodying my invention. Figs. 2 and 3am horizontal sections through the 'arlulreting-r'hamlicr antl aportion of the tion of line 2-2, Fig. 1. Fig. :h is'a de ttlfjllll'll perspective view of a nozzlewarricr with the aspiratingnozzles secured thereto.

Referring now to the drawings in detail, like letters of reference refer to like parts in the seperal figures.

lhe reference letter A designates the carhuretcr considered as a whole, and it consists of a gasolene fcedchamlier A and a tLl HIl'ttlllg 'llttllt nl A herein shown as ast in one piece. but as this is merely a matvertical hore l threaded at its upper end, as

her of choice, the) may be otherwise constructed. The carluireting-chamhcr and the gasoleno t'eed-rhalnhcr are connected by a neck X having a conical lJOHn (L on its under side which terminates in a threaded i('i|l o. Cast integrally ith the gasolcuc trawl-chamher on the under side thereof is an inlettuhe 13 having a threaded opening 7) at a,

point coincident with the -axis of said feedchamherwvhich is closed with a screw-plug N. The inner end of the tube B is in communication with the interior of the gasolenc feethchamher through a passage C which is beveled, as at c, to provide a seat for a valve D arranged on the lower end of a valvestem (1 passing through said passage. The upper end of the gasolene feed-chainher is closed by a cover E having a guide-opening 6 arranged therein in line with the passage C in the bottom of said ehamlier, and in said guide-opening e the valve-stem (Z is guided for movement. The valve at the lower end of said stem is adapted to close upwardly against the valve-seat a, so as to prevent the feeding of gasolene to said teed-chamber. As is common in gasolene controlling-deviees of this kind, the valve-stein. whereit passes through the passage C, is of square formation in cross-section, as shown in Fig. '2, so that when the valve D is unsealed, the gasolene can pass upward through the passage (l. Secured to said valve-stem is a float which controls the opening and closing of the valve .1) when the level of the gasohme in the gasolene feed-clmi'nl'ier lowers and rises and it serves to maintain the gasolene at tl'ierequired level in the gasolene chamher, irrespective of the conditions to which the device may he subjected.

The tm'hureting-cliamher A is in the t'orin of a plain cylinder having both ends open and one'end ekternally threaded for connection of a pipe leading to the ignitionchamher of an engine. By thus constructing the carliureting-chamber, a straight passage is provided therethrough for the passage of the air. thereby almost entirely eliminating the resistance offered to the air in compelling it to travel through curved or winding passages, as is commonly practiced. Moreover, by disposing the passage horizontally, the air enters andleaves the carburetingchamher more freely.

In the neck connecting the gasolene feedcluunher \\'ith the carhureting-clianiher is a at f, and provided at its lower end With a t:lperingpoltion f terminating in a small cylindrical portion f extending down into the conical hose (1, which boss has a small lateral bore f extending outwardly from the lower rcrh'u'ed end of said vertical bore.

.\ paswge G connects the vertical bore F of said bore so that it may restrict or close the flow of gasolene from the gasolene icedchamber.

Secured to the boss or is a imzzle-carrier l which coin )rises a tube ti having a flat cylindrical head 2' provided with a beveled open ing 2' through which the conical hoss .u is

adapted to pass. The hore of the tube 2' extends from said beveled opening to the opposite end of the tube and is threaded at said last-mentioned end to receive a screwplug i and said hore. when the carrier is applied, rcgistt'rrs with the lateral hore f in said conical hoes. forming in ell'ect a continuation of said lateral here. Secured to the threaded stem 5:. of said boss is a nut J wherehy the nozzle-carrier forced upward on said conical boss and held in proper position. Threaded into said tube '1' are two aspirating-nozzles K, K, adviscdly of different lengths, so that the upper nozzle K nearest the gasolene-ohamher is in a lower horizontal plane than. the other nozzle K.

The carbureting-chanihcr is provided with two openings at points on opposite sides of its vertical center, through which openings the aspirating-nozzles extend. The nozzle K terminates at the horizontal center of the chamber and the nozzle K at a point slightly below the center. The passage (i connecting the gasolene fecdchan1l)er with the bore 1*,

the lower end of the bore l" with its lateral extension f and the bore of the luhe 2', serve as a passage for feeding the gasolene from said feed-chamber to the aspirating-nozzles.

' A controlling-valve L is provided which is in the form of a butterfly valve or disk passing through a stern M, journaled for rotation in the top and bottom of the carhureting-chainher and extending up through the top of said chamber for connection thereto of a manipu attngdever N which may he operated in any convenient manner from a distant point. Said valve has two semi-circa lar winganetnhers L, L arranged at a slight angle to each other so that when theiving end of ill? Figs. 2 peculiarly situated with reference to the stem of the valve and for this purpose the nozzle-carrier is arranged diagonally, as shown in dotted lines in Figs. 2 and 3, the nozzle K being close to the inner wall of the carhureting-chamlJu-r and approximately in line transversely with the stem of the valve so it at when the valve in closed position. said nozzle is in close proximity to the edge of the \ving-ntcm u-r it. The nozzle K. is localctl hetwecn the vertical center of the carhnretingaihanther and its outer w: ll and a distance from the stem oi the valve M so that the edge of the wing-member If will. just clear it when the valve is lining swung into full open position. The purpose of making the aspirating-nozzles oi dill erent lengths is to compel the air drawn or passing over the upper ends of the nozzle to have an aspirating ntTot-t upon the nozzle K hetore it acts upon the gasoline in the nozzle K hut after the velocity oi the air currents increase by reason of the controlling valve being opened, the aspiration client will he upon both nozzles.

By arranging the nozzles relatively to each other and to the valve as shown. the proper proportion of gasolenc to air will always he Hlllllitllliitlv lllt l)t'tll\'t. ot' the speed of the engine and the velocity of the air currents. When the controllingwalve is in the position shown in Fig. :5, it is set for low speed. Flu:edgeoil the valve to the right of its stem is then in contact with the wall of the carhurcting lttttilllt'i' while the opposite edge is separated from the "all of the chamber by a slight space U. see l' igs. Z and 3. The air at such times passes over the nozzle K. carries with it a proportiona e amount of gaeol ne in spray l'orlu takes a slight angular (Jttlll'--t. and passes through the space 0 between the huttcrtlv valve and the wall of the carhuretcr. when in this positi n. the air passing through lilt' carhuretingchatnher (loos not. act upon the rum zle K, owing, to the distance of said nozzle from said space. The gradual opening of the valve in the dire tion shown hr the arrow l in Figs. 2 and 3 causes an incr-ase in velocity of the air and a proportionate increase of gasolene from the nozzle K owing to the spa e her L and the wall of the carhuretlngchamber luring increased, and during this opening movement of the valve the wingn'teinlicr L moved toward the nozzle K and acts as a shield for said nozzle until the space hetween the edge of said iast-ntcn and The aspirating-nozzles are between the wing-inconmemher If is directly at a rigl1t-angle to the axis of the carburetingchamber and closes iioltcll \Vlltg ltlfilltll trl and the \all of the 123 the space hetween the stem M and the wall chanihcr is of a certain area.

inany position within range of such movement. When the valve is opened to a greater degree, the velocity of the air-currents increase and act upon the nozzle- K,

and have a slight as irati'ng effect upon the same also, which e cct is lncreased as the wing-member L approaches said nozzle and permits the air to pass between the spaces on opposite sides of the valve.

\Vhen the valve approaches the position shown in Fig. 4, the air currents have a full aspirating effect upon the nozzle K and approach almost full efi'ect on the nozzle K, and in this position the valve is arranged for high speed. Highest speed is obtained when the valve is in the position shown in Fig. 5 at which time the air currents have It is apparent, therefore, that the speed of the engme may be governed to a nicety by the mere manipulation of the controlling-valve and that the greater-the Valve is opened the higher the speed at which the engine may be run.

Havin thus described my invention, what I c aim is,-
