Application aie-amy 29,
This invention relates to vital improvements in carhuretors and the primary object of the invention is to provide a novel carburetor having an improved means for thoroughly mixing the air and fuel"`charge together, and for atomizing and breaking up the -fuel charge into small particles, thereby permitting the effective use of heavy fuel such as coal-oil and the like.
l Another prime object of the invention. is the provision of a rotatable draft operated propeller disposed in the carburetor for effectively mixing the charge prior to 'the entrance thereof into the intake manifold,
l5 4the prrpeller serving as means for mixing the air and fuel together and breaking up the fuel into small particles.
v 4Another prime object of the invention is the provision of a rotatable propeller and propeller shaftmounted in the body portion of the carburetor adapted to be rotated by the flow of fthe charge past the same, the `propeller shaft being of a hollow construction and having outlet pipes 'carried thereby and -connected with propeller` blades, the pipes serving as means for spraying out the fuel into the mixingl chamber of the carbu retor...
A still further object of'theinvention is to provide an improved carburetor of the above character, which will be durable and efficient in use, one that willbe simple and easy to manufacture and one which can he placed upon the marketl at a reasonable cost. With these and other objects in view, the invention consists in the novel constructin, arrangement 4and formation of p'arts as will be hereinafter' more specifically described, claimed and illustrated in the accompanying drawings, in which drawin s:
Figure 1 isa vertical longitu 'nal section f through the improved carburetor.
Figure 2 shows perspective views of certain parts of the improved carburetor.
Figure 3 is a horizontal section through f the carburetor taken on the line 33 of Figure 1. VFigure 4 is a horizontal section through 5o the carburetor taken on the line 4-4 of Figure 1. Figure 5 is a horizontal section taken through the float chamber of the improved v carburetor on the line 5-5 of Figure 1.
.cylindrical mixing chamber 14 is 1923'.v Serial N0. 642,280.
nate corresponding parts throughout the sev eral views, the' letter A generally indicates the improved .f'carburetor, which includes the fuel bowl 10 having its lower end provided with ay plug ,11to permit the draining of the carburetor when necessary or desirable. The upper fend of the bowl 10 is provided with an outwardly `extending annular attaching flange 12, .to which is adapted to be connected by means of bolts 13 the cylindrical mixing chamber 14. As shown the lower end of the mixing chamber 14 is also providedwith an annular attaching iange 15.
A perforated mixing plate 16 is dis osed between the bowl 10 and the mixing c amber 14, in order to prevent the splashing up of the fuel in the bowl into said chamber. This plate 16 Ais preferably clamped between the flanges 12 and 15 and is.provided with a plurality of openings 17 through which excess fuel is adapted to fl'ow back into the bowl l0.v The axial center of the plate 16 supports a bearing 18, for a-purpose, which will be hereinafter `more fully described. As shown the extreme upper end ofthe rovid'cd with a reduced neck 19 in which is tted ythe usual type of throttle butterfly valve 20 for controllingthe flow of the charge into the intake manifold. The extreme upper end of the reduced neck 19 carries an attaching lian e 2l to permit the connection thereof to t e said intake manifold.
Communicating with one side ofthe fuel bowl 10 is a valve chamber. 25 provided with a suitable valve seat 26. An inlet nipple 27 extends below the valve seat and is adapted to receive the usual fuell inlet pipe or tube leading from the source of the fuel A'loat 30 is disposed within the fuel bowl 10 for controlling the flow, of fuel into the bowl and the float is connected through the medium of an arm 31 with a needle valve 32, which is adapted to fit upon the valve seat 26. las clear y shown in Figure 1 of the drawings the arm 31is pivotally mounted. at a point intermediate its ends upon a suitable bracket 33.
The valve chamber is provided with a removable plug 28, which is disposed directly above the valve seat, Wwhich permits the cleaning of the valve and seat `when necessary or desirable;
The mixing chamber 14 adjacent to its upper end supports a spiderl 35, the axial' center of which is provided with a suitable 4type of thrust bearing 36.
y A rotatable hollow propeller shaft 37 is rotatably mounted within the bearing 18 and the 'thrust bearing 15 and has its lower end disposed within the fuel chamber 10. The
propeller also support relatively small radi as means for mixing the fuel 'and air to-v gether andl for breaking up the fuel into The hub and blades of the ating tubes 40 which communicate with the bore ofthe hollow propeller shaft 37. During the rotation of the propeller and shaft. the fuel is sucked up ythrough the shaft and tubes 40 and sprayed out into the mixing chamber, where the same mixes with the air.
The chamber 14 can have the outer wall thereof provided with a plurality of air inlet openings 41, which are preferably covered with suitable fabricated plates 42, which act as screens for preventing any foreign matter from entering intothe mixing chamber.
tion, vin wliich-means is provided for breaking up thefuel into small particles and for insuring the thorough mixing thereof with the air.
Changes `in details may ybe made without departing from the spirit or the scope of` this invention.
lVhat we claim as new is: 1. A carburetor comprising a fuel bowl,
means for controlling the level of, liquid in said bowl, a mixing-chamber` connected with the upper end of the bowl, a plate withl multiple perforations disposed between the mixing chamber and bowl having an axial shaft bearing formed therein, a spider carried by the upper end of the mixing champlat'e disposed between the mixing chamber and bowl having an axial shaft bearing formed therein, a spider carried by the upper end of the mixing chamber, 'ai hollow propeller shaft rotatably carried by the bearings of the plate and spider and having its lower end extended into the fuel bowl, radial ber a hollow propeller shaft rotatably carf blades carried by the hollow propeller shaft.,
hollow tubes carriedby the upper faces of said blades. and communicating with the It is also preferred to mount a screen 43 bore of the propeller shaft, a throttle valve in the inlet nipple 27 directly below the valve seat 26, so as to prevent the entran-ce of any exceptionally simple and durable Aconstruc- 4 arranged above the propeller, and means for said propeller. v
In testimony whereof we aix our signasupplying air to the mixing chamber below Y,
