CARIjBURETER FQR INTERNAL-COMBUSTION ENGINES.
Specification of ietters Patent.
Application filed February 26, 1910. Serial No. 546,172.
To all whom 'it may concern:
Be itknown that I, WILLIAM VViLsoN HAMILL, a subject of the King of Great Britain, residing at Glasgow, Scotland, have invented certain new and useful Garbureters for Internal- Combustion Engines, of which the following is a specificatiop.
This invention relates to improvements in carbureters and is applicable to internal combustion or explosion engines of all types, more particularly to engines using heavy liquid hydrocarbon fuels, and has for its object to improve the construction of same and to pro-vide simple and more efficient means whereby the density and temperature ol the mixed gases supplied to the engine are automatically maintained constant, and whereby the proportion of hydrocarbon to air -may also be' controlled independently when required.
My invention also insures a homogeneous mixture of the gases, and provides-a corrective means whereby the volu me of the mixed gases is automatically regulated and proportioned during sudden variations in the re- .quirements of the engine, such as when suddenly slowing down from its accelerated speed to its minimum, and whereby the tendency to flooding or pooling due to the inertia of a column of liquid fuel emitted through an unrestricted jet orifice, is entirely obviatcd, giving practically perfect combustion at all times; this flooding, in
theordiiiary jet, interfering with proper tion. Figs. 2, 3, 4f and 5 are detail views oi'l the spraying nozzle o, double truncated cone piston y', and throttle valve spindle n, hereinafter referred to. Fig. (3 is a detail view of a modified form of the double truncated cone piston hereinafter described.
On the drawings the same reference letters wherever repeated indicate the same or similar parts.
Under my invention the carburetor comprises a Vspraying nozzle a which is surrounded -by two semi-cylindrical and detach- `able covers Y), the head of the spraying nozzle a having a number yof radial orifices c at right angles toitsaxis, and its axial passage l being closed at its upper end, preferably by a screw c which can vbe removed for cleaning purposes, and being provided lwith the usual needle valve f at its lower end for coh- Patented Mar. 12, 1912.
double conical or truncated-cone piston y' and air is drawnin between this cone jand the sleeve (7 into an upper compartment of the carbureting chamber, (Fig. 1) the minor diameter of said cone y' in its normal position being coincident with the center' of the fuel outlets z', and said cone having a crosshead or spider Z which is connected to a ccntral spindle fm adjustably connected to an outer concentric throttle valve spindle n, the position of these spindles m and n being regulated by nuts 0 and y), the construction being such as to allow adjustment of any elcment while the engine. is running and without interfering with or fouling any of the other parts. The double truncated cone piston j is, or may be, provided also with a series of orifices or slots g, as shown in Fig. G, the air entering the orifices g and mixing with the fuel above the fuel outlet orifices z withoutincreasing 'the suction at the fuel outlet orifice.
In the arrangement shown in Fig. l" the lower part of the cone piston j is provided with orifices Q, these orifices g being adapted to communicate with a recess 9 in the upper compartment lc, when the cone piston is raised as shown in dotted lines, thereby admitting air above the spraying nozzle a. The sleeve g surrounding the spraying nozzlc nA is formed `integral with a bridle r which crosses the spider or crosshcad Z at right angles, the upper boss or collar s of the said bridle 1' sliding on an extension of the hollow throttle valve spindle n and being held in its normal position by a spiral spring u on thc throttle valve spindle n. On the throttle spindle 'n is mounted a piston throttle valve n which slides in a concentric throttle sleeve l havingports Z, this l sleeve w being fixed into an ordinary valve chamber m (Fig. l) by a iange y which is used to locatethe whole apparatus centrally in the upper compartment c and which acts as a stop for lugs c provided about midway on the aforementioned bridle 1 the said valve chamber .fr communicating with the outlet to the engine manifold. The piston throttle valve o is provided, at its upper end, with an outwardly turned rim or iange 1 which acts as a stop, in its normal position, by abutting on the upper rim of t-he throttle sleeve w, and, on the upper extremity of the throttle spindle a, a collar 2 or other suitable means is provided for raising and loweringthe hollow spindle n, this collar 2 being operated either by hand from a suitable controlling lever 2 or by automatic means, such as the engine'governor. The lower compartment 3 of the carbureting chamber is surrounded by a hollow jacket 4,
which is in connection with the main eX-.
haust pipe 5 for the purpose of heating the earbureter, the temperature of said jacket 4 being controlled by a thermostat of any suitable type,'and a swivel door or cover 7 is provided to give access to the interior of the jacket 4. The swivel door 7 (see also Fig. la) is hinged aty 31and is provided with a bridge piece 32 -which is adapted to engage a pin 33 on the ,casing 34, a screw'35 and handle 36 being provided whereby the door 7 is caused' to make an ,air-tight joint with thecasing 34 when the handle 3G is given a slight turn. The hydrocarbon is heated before admission to the lower compartment 3 by passing through a jacket 8, surrounding the exhaust pipe 5, thereby raising the temperature of the fuel to that at which vaporization will lreadily take hydrocarbon to the upper compartmentc of the carbureting chamber, air passing between the sleeve g and the surrounding cone y' and :mixing with the hydrocarbon, and, in this position, the lug-s .e on the bridle y 7" abut against the flange y fixed in the upper compartment is, thus limiting the upward movement of the slee-ve g' and Vbridle r, while Y the piston throttle valve t' being slightly raised, opens communication by the ports t of the sleeve ,tu from the upper compartn'ient 7c.. to tlie engine cylinder. As the engine increases in speed the valve spindle n is further raised, thusdrawing up the cone j and increasing the areabetween it and the sleeve g of the spraying nozzle a, and admitting more air to the upper compartment 7c, which, by reason of the increased suction, draws more hydrocarbon in with it, thus maintaining the proper proportion of air to fuel. The ports of the sleeve fw are further uncovered, as the spindle aand throttle valve U continue to rise until the ports are full open or until the required volume of the mixed gases is entering the combustion chamber, while, at the same time, the spring u on the spindle n is compressed against the boss s of the bridle r. When the engine speed is reduced, the mechanism controlling the engine closes the throttle valve o, and the cone j moves vert-ieally downward, thus reducing the air supply, and, as the throttle valve v and cone j-are nearing the end of their downward vmovement, the spring u on the valve spindle n relaxes. When the boss of the throttle valve 'U abuts against the upper boss or collar s of the bridle fr, the sleeve w and bridle r. are moved downward, thus covering or partially covering the orifices c, as desired, and thereby cutting o or restricting the fuel supply and preventing excess of oil in the upper compartment 7c.
By my improved construction of carbureter the proportion of hydrocarbon to air is automatically controlled and the density maintained constant at all speeds of the engine, thus giving practically perfect combustion, but, if desired, the proportion of hydrocarbonto air may also be cont-rolled independently when required, .as for example, when using oils of varying constituencies by adjusting the-relative positions of the central spindle m and the outer concentric throttle valve spindle n. j
