FUEL-MIXING AND CHARGE-CONTROLLING DEVICE FOR EXPLOSlVE-ENGINES.
SPECIFICATION forming part of Letters Patent No. 734,415, dated July 21, 1903, Application filed August 18, 1902. Serial nailzaoso. .lNo model.)
DREW GRIEBEL, citizens of theUnited States of' America, and residents of Cleveland, county of Cayahoga, and State of Ohio, have invented certain new and useful Improvements in Fuel- Mixing and Charge-Controlling Devices for Explosive-Engines, of which the following is a specification.
Our invention relates to improvements in hydrocarbon explosive-engines,and theobject of our improvement is to provide a simple, efficient, and reliable contrivance for mixing the fuel in proper proportions as to air and gas and to control manually the quantity of fuel (charge) for such engines. Preeminently these improvements are intended for vehicle-motors. 'W e attain'these objects of our improvement in a contrivance constructed substantially as shown in the accompanying drawings, in which V Figure 1 represents a-partial longitudinal sectional view of such motor provided with the improvements above referred to. Fig. 2 is a partial end and cross-sectional view of the same. I
Like letters of reference vdenote like parts in the drawings and specification.
In the illustration herewith given, A designates the cylinder, B the piston, G the inletvalve, and D the outlet-valve, of and for an explosive-motor. With the casing E of the inlet-valve we combine or attach a fuel feeding and mixing device, which is contained in the supplementary casing E. (See Figs. 1 and 2.) By way of branch a fuel is conveyed to the needle-valve orifice b, which intersects with the mixing-valve seat 0, the flow of the liquid being under control of the needle-valve F. The mixing-valve G controls both the seat 0 as well as the orifice 1). Air enters from below the seat 0. a lever H, which is operatively connected with the bell-crank I. The latter lever I is arranged for manual or foot operation and under such adjustment allows the inlet-valve O to open more or less according to the charges required, as presently described. The spring J is applied to hold the valve 0 normally to its seat d, and said spring is interposed between the casing E and the adj ustable'nut 6 upon the valve-stem f. As shown, the lever To the needle F is secured I has its fulcrunrg upon bracket h, which bracket may be an integral part'of casing E or it may'have independent connection with some stationary part of the cylinder. The
arm'i of leverI is bifurcated, as at c", and extends under the nut e, and by means of setscrew j and spring 70 more or less clearance can be established between the terminal 2 of the arm and the nut ,above referred to.
The aunt of lever I is connected with the foot- I With the exten sion '1' of'lever I. and needlevalve lever H is connected the rod 0. Thus upon pushing the lever K in direction of the arrow the needle-valve F can be withdrawn at the same time as opportunity is given to the valve Oto open to an increased extent that is, when the arm 't'of lever I is lowered and the resistance of spring is is removed. Originally the needle-valve F is so adjusted as to admit of a flow of liquid fuel, which is just sufficient for a throttled charge, but as soon as a full or an increased charge is admitted into the cylinder then the needle-valve is caused to recede from the orifice bin order to admit simultaneously an increased flow of liquid or as much as may be required for a plosive and suitable for complete perfect combustion no matter whether the motor is running light, at full capacity, or intermediate charges. The motor is running light as long as there is'no pressure brought to bear against the lever K; but as soon as the'operator presses with his foot against said lever then the valve 0 becomes more or less released from the resistance of the spring 7c and at the same time a freer How of liquid is effected, owing to the receding of the needle-valve F. Obviously the lever I might be arranged or equipped for manipulation by hand. However, in connection with motor-vehicles foot operation is preferable.
What we claim, and desire to secure by Let ters Patent, is
1. In an explosive-motor, the combination with the inlet-valve and its seat, and a spring for normally holding it to its seat, said valve being subject to the suction action of the piston; of a stop independent of the spring located in the path of movement of the valve to limit its movement, said stop being nor mally held fixed in a predetermined position, a mixing-valve with adjacent liquid-feed, a needle-valve controlling said feed, and means for manually varying the position of said stop and needle-valve in one direction to permit of sudden increase of the charge and speed of the piston.
In an explosive-11101201, the combination with the inlet'valve and its seat, and a spring for normally holding it to its seat, said valve being subject to the suction action of the piston; of a stop independent of the spring located in the path of movement of the valve to limit its movement, said stop being normally held fixed in a predetermined position; the position of said stop relative to the valve being adjustable, a mixing-valve with adja' cent liquid-feed, a needle-valve controlling said feed, and means for manually varying the position of said stopand needle-valve in one direction to permit of an increase of the charge and speed of the motor.
3. In an explosive-motor, the combination with the inlet-valve and its seat, and a spring for normallyholdiug it to its seat, said valve being subjected to the suction action of the piston; of a bell-crank lever having one arm reaching under the head of the stem of said valve and forming a stop therefor; a set-screw and spring retaining the lever normally, hold in g said stop fixed in predetermined position, a mixing-valve with adjacent liquid-feed, a needle-valve controlling said feed and means for manually varying the position of said stop in one direction to permit of an increase of the charge and speed of the motor.
4. In an explosive-motor, the combination with the inlet-valve and its seat, and a spring for normally holding it to its seat, said valve being subject to the suction action of the piston; of a bell-crank lever having one arm reaching under the head of the stem of said valve and forming a stop therefor; a setscrew and spring controlling the normal predetermined distance between said arm and the head of the valve-stem, a mixing-valve with adj aeent liquid-feed, a needle-valve controlling said feed and a foot-lever and rods operatively connected with the free arm of said bell-crank lever and needle-valve lever for manually varying the position of said stop and needle-valve in one direction to permit of an increase of air and liquid charge.
