UNITED STATES PATENT rmcn.
FRANK H. HEITGER, 0F INDIANAPOLIS, INDIANA.
CARIBURETER.
To all whom it may concern:
Be it known that I, FRANK H. Hnrronn, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered cer tain new and useful Improvements in Carburetors, of which the following is a specification.
My said invention consists in certain improvements in the details of construction and arrangen'ient of parts of carburetors and it especially relates'to the mechanism for controlling the feed of the gasolene, or other hydro-carbon fluid, whereby the supply may be automatically regulated to suit the speed of the engine and conditions under which it 'is operating, all. of which will be hereinafter more fully described and claimed.
Referring to the accompanying drawings, whicl'i are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 represents a side elem-1- tion of a carburetor embodyin; my said invention Fig. 2 a central vertical section through the same; Fig". 3 a detail showingportions of Fig. 2 on an enlarged scale: Fig. 4t a cross section on the dotted line -t-t in Fig; 3; Fi 5 a cross section on the dotted line 5-5 in Fig. 3, and Fig. 6 a detail view showing, a modification in the structure.
In said drawings portions marked A rep- .l'klSQlli. the mixing chamber, B the 'asolene reservoir or float chamber. C an annular ring or casing section interposed between the top of said float chamber and said mixing clnnnl'ier, and D the main air supply pipe. In the main these several parts as shown are of substantially a common construction, such as used on the well-known I-Ieitg'er earloureter, and require no special description, except incidentally in describingthe other parts to which my invention particularly relates.
The main features of construction. so far as novelty is concerned, are shown and described in detail in my companion applica tion No. 702,616, The auxiliary air inlet valve 40 is mounted on a spring; 4-1 as particularly shown and described in my companion application No. 70.),612.
The mixing chamber has a suction tube It depending therefrom on the lower end of which is mounted a casting 11 containing the inlets for the grasolcne and for the air. The spray nozzle 12 is screw d into the top Specification of Letters Patent.

of the aperture in said casting 11 and is formed hollow and with a tapered seat 14: for the needle valve as most clearly indicated in Fig. 3. i
The needle valve 15 comprises a hollow stem having a conical lower end adapted to fit within seat LL and having longitudinal grooves spaced around its periphery near its lower end forming channels 16 through which the supply of gasolene may be drawn into.the carbureting chamber. The lower end of the perforation which extends centrally through the stem 15 is 01'' small diameter and the upper end of a larger diameter, a shoulder 17 being formed between the large and small portions of the here. As shown the extreme lower end is provided with a tip 25, with a small central perforation therein, driven into the lower end of the tubular stem 1:"), which may be made of stock tubing for purposes of economy in constructiml. A. reciprocating cylindrical valve 18 with a conical lowrr end is mounted in the Large portion of the bore with its point adapted to extend within and seat in the top end of the small ortion at shoulder 1.7. An adjustable screw 1.) is lllOllllllUtl in the upper end of said bore formed with a head 20 having; a ribbed periphery adapted to engage with a holding s 'irincdfletent 2t mounted on an adjaemlt part o'llhe casing. The upper end of stem 15 is also provided with a head havil'igg a ribbed periphery which engages with i i I an adjacent part of the casino. Said stem is screw-threaded for a distaui-e just under said head and is mounted in a screw threaded perforation in the casing i as shown. thus providing for the :uljustment thereof to fix the normal .Q'VISOllUt 'l'eed Ulotlllltg through the spray nozzle. Radial perlorw tions 24- are 'l'orlncd through the wall of said stem leading into the portion of the bore containingthe sliding valve 18 tor permitting the gasolene to pass to the mixing' chamber when valve 18 is raised from its seaton shoulder 17.
In operation the needle valve is adjusted by means of the head J2 to admit the normal quantity of lluid l'uel desired through the grooves it in the peripherv ol' the lower cud of said stem 1.3 and through the spray noz- "/.le. Haid supply \\'Ill be lixcd and reculated to the supplv murded for low speed. On the increase of the speed and the increase of the suction caused thereby, the

pressure or suction will be suflicient to cause valve 18 to rise in the enlarged upper end of the bore in stem l5 free from its seat on shoulder 17 and permit an additional supply of gasolcne to flow through the central perforation in said stem and out through said radial perforations 2-1 into the mixing chamber. As the speed of the engine decreases, the weight of said valve 18 will cause it to fall and seat upon shoulder 17 and cut off this additional supply of gasolene. By means of the adjustment of screw 19 the vertical movement of said valve 18 may be limited so as to form a larger or smaller passage through the aperture at shoulder 17 when said valve is lifted to the limit of its movement. By this means the supplyof fuel at the highes s 396d may regulated and accurately limited as desired. In Fig. 6 the means for regulating the supplemental supply of gasolene through the hollow stem is omitted and the parts shown to be fixed in a standard adjustment, any regulating desired being by means of the needle valve itself through the spray nozzle.
What I claim is- 1. In a carbureter, carbureting and mixing chambers, a fuel regulating mechanism comprising a hollow needle valve control ling the aperture leading from the fuel supply to the carhureting chamber, means for adjusting said needle valve to regulate the normal supply of fuel which may flow around the sanie, and an internal valve mounted within. said hollow needle valve for controlling the flow through said needle valve to the mixing chamber, substantially as set forth.
2. In a carbureter, carbureting and mixing chambers, means for regulating the supply of gasolene to the carbureting chamber comprising a needle valve consisting of a hollow stem with a valve on its lower end, means for adjusting said valve the supply flowing outside of said valve, openings from the interior of said stem to the mixing chamber, a sliding valve Within said hollow stem arranged to control the flow through said openings, and means for limiting the movement of said Valve, substantially as set forth.
A carburetor comprising carbureting and mixing chambers, means for regulating the supply of gasolene consisting of a needle valve carried on a stem, said stem formed with a longitudinal bore of different diameters with a shoulder between them, a valve mounted in the section of the bore having the larger diameter adapted to seat in the end of the section having the smaller diameter, openings leading from said larger bore into the mixing chamber, a valve for controlling the flow through said bore, and means regulating said valve, substantially as set forth.
MA carbureter comprising carbureting and mixing chambers, means for controlling.
to regulate the feed of the gasolene to the carbureting chamber consisting of a needle valve adapted to control the spray nozzle said needle valve being formed with a longitudinal bore, apertures leading from said bore to the mixing chamber, and a valve for controlling the flow through. said bore, substantially as set forth.
In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana, this 21st day of May, A. D. nineteen hundred and twelve.
