Application filed December 2, 1909. Serial No. 531,022.
concern:
. Be it known that I, WILLIAM M. GENTLE, of Greenwood, county of Johnson, and State of Indiana, have invented a certain new and useful Carburetor; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.
The object of this invention is to provide a carbureter that will produce a uniform mixture of air and vaporized fuel for the engine while the speed is increasing or decreasing, and in that connection I provide an automatic means for regulating the intake of air and vaporized fuel so that a desired. uniformity of mixture is maintained. In explosive engines where the air and fuel are mixed before they are introduced into the cylinder, it is necessary that a nearly uniform rat-i0 of the two be maintained to develop satisfactory power either at high or low speed.
The invention will be understood from the accompanying drawings and the following description and claims.
In the drawings Figure 1 is a central vertical section through the carbureter in idle condition, the control lever being in position to direct all the air through the mixing chamber. Fig. 2 is a section on the line 2-2 of Fig. 1, and partially broken away. 3 is the same as Fig. 1 with the position of the control lever altered and the air passing through the carbureter, as indicated by arrows. Fig. 4 is a section on the line 4-4 of Fig. 1. Fig. 5 is a plan view of the device.
In detail I provide a bowl 10 open at the top and having a tubular vertical interior wall 11 which is integral with the base of the bowl and extends upwardly therefrom, and which is open at the top and bottom, thereby forming an air passageway. The upper part of the bowl 10 is threaded to receive the threaded portion of the casing 12, which forms the mixing chamber 13 and the top of the bowl 10. The casing 12 has a central downwardly extending tubular portion 14; that surrounds the air tube 11 but is spaced away from it slightly to form a passageway 15, through which liquid fuel may pass from the bowl to the mixingchamber. As seen in the drawings, the tubular port 14 does not reach the bottom of the bowl 10 to permit free access of the fluid to the passageway 15.
On one side of the bowl 10 and integral with it is the valve casing 16 for the fuel inlet valve 17. The stem of the valve 17 extends upwardly through a partition wall 18 in the casing 16, and at its upper end is capped to retain the spring 19, which normally holds the valve 17 open. A valve seat 20 is threaded and screwed into the bottom of the casing 16 with a port 120 through it in position to be closed by the valve 17 A liquid fuel supply pipe 21 is screwed into the base of the valve seat 20. A fuel passageway 22 leads through the partition 18 into the chamber of the bowl 10. The bowl is provided with the usual float 24: secured to one end of the lever 25, which is fulcrumed near the center on the pin 26. The other end of the lever 25 is threaded to receive the adjustable screw 27. By means of the float and the mechanism just described, a predetermined amount of liquid is admitted and maintained in the bowl.
A tubular extension 28 is integral with the casing 12 and extends upwardly therefrom and is th'readed at its upper end to receive the tubular valve casing 29. The latter is turned at right angles to the pipe 28 and one end 40 is the air inlet, and the other a passageway to the intake port of the engine cylinder through pipe 30.
In the center of the valve casing 29 a valve 32 is pivoted at its upper end by a pin 33 and depends therefrom at an inclination, so that gravity tends to close it, and also a spring 3 L tends to hold it closed. It extends across the passageway to the intake pipe 30, and, therefore, performs somewhat the function of the usual throttle valve, although it is automatic and not manipulated. It opens upwardly toward the intake pipe 30 and closes downwardly against an annular seat that is formed by contracting the passageway through the casing 39 to some extent, see Fig, 3. One end of said spring 34 is connected with the valve 32, and the other end to the adjustable screw 35 in the casing 29.
In the upper part of the casing 29 there is an air inlet opening over the valve 32, which has an area substantially equal to the transverse area of the passageway leading from the throttle valve and which is closed by a valve 36, and which might be termed the relief or back-firing opening and valve. It is horizontally disposed and is pivoted at one end on the pin 37 to the upper part of the casing 29, and is held down and closed by a flat spring 38, which is secured at one end by screws to the casing 29 and at the other end extends through the space between the valve 36 and the strap 136 on the underside of the valve. On the occasion of back firing, the back rush of gas would close the valve 32 and open the valve 36 to ,the dotted line position.
The secondary air inlet 40 is at one end of the casing 29 opposite the intake pipe 30, with the valve located midway between said ends of the casing 29. Thetransverse area of the air inlet 40 is preferably less, about one-fourth less, than the area of the intake pipe 30, so that some air will always pass up through and from the main air inlet 11 below, or at least this is true while the device is operating normally and the valve 32 is open and until the valve 36 is opened. The air inlet 40 is controlled by a butterfly valve 41 on a pin 42 mounted transversely in one end of the casing-29. There is a lever 43 on one end of the pin 42 for actuating the valve 41. On the other end of the pin 42 there is a finger 44 adapted to engage the ear 45 on one edge of the valve 36 to open it, seeFigs. 4 and 5, and the dotted-line position in Fig. 3. The lever 43 may be operated by any suitable connection therewith.
The upper surface of the tubular air inlet 11 is ground to fit the under surface of the disk-like valve 46, which is secured to the stem 47. The latter is slidably mounted in the bearings 48 and 49. The bearing 49 is a spider secured to the wall 11. The bearing 48 is adjustably mounted in the spider 50, which is secured in the extension 28. The lower end of thebearing 48 has a head- 51 which engages one end of the spring 52. The other end of the spring rests upon the upper surface of the valve 46 and tends to hold the valve closed. Secured to the edge of the disk 46 there is a tubular wire fabric '53 which extends downwardly about the air in et 11 and through the passageway to --a point near the bottom of the bowl 10. The fabric is adapted to move upwardly and downwardly with the opening and closing of the valve 46. I do not desire to be limited to a tubular fabric,-as any means such as vertical wires, or the like, may operate to accomplish the same pur ose,
In operation, the englne is started with the valves of the carbureter in the position shown in Fig. 1. Suction from the piston opens the valves 32 and 46, the springs 34 and 52 being of slight resistance. As the an valve 41 is closed, all the air taken into the cylinder must pass through the fluid saturated screen 53, whereby the fluid becomes vaporized and the air charged. As the valve 46 tends to reseat after each stroke of the piston, it can be readily seen that the screen will be kept moist. As indicated by the arrows in Fig. 3, the air passing through the screen 53 strikes the lower surface of the explosive gas v a casing 12 and moves toward the center of the chamber 13, thereby making'a very thorough mixture of the vaporized liquid and air.
This movement of the air tends to draw the passageway 15 and disperse 7p liquid from the it through the air. With the valves maintained in this position, the engine would immediately run to the maximum power. The 7' by opening air and less power may be reduced, however, the air valve 41, whereby'morevaporized liquid will be taken into the cylinder. As seen in Fig. 3, the outside air passing through the port 40 mixes with the maintain any desired proportion of mixture with but slight the piston.
