To nlZ whom it WWI/y concern:
Be it known that I, JOHN V. LAMBERT, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and usefulImp'rovements in Mixers for Gasolene-Engines, of which the following is a specification, reference being had therein to the ac companying drawings, in which Figure 1 is a Vertical sectional view of my device; Fig. 2, a detail end view of the spraying-cone, and Fig. 3 a horizontal section on the line 3 3 of Fig. 1. Figs. i and 5 are views showing the manner of connecting the mixer to the engine.
Referring to the drawings by letters, a designates the intake-pipe ofthe engine-cylinder 1), this pipe being provided with a depending branch I) at or near its closed end 0. Surrounding the depending branch b of the intake-pipe is a gasolene cup or reservoir d, which is closed at its ends and is preferably formed integral .with the said intake branch. Projectinginto the intake-pipe is a chamber 6, which is formed integral with the wall of said intake-pipe and communicates with the gasolene-cup, so as to fill with gasolene when the cup is filled to the proper level. A pipe f is connected to the gasolene-cup and to a suitable tank g, containing gasolene, a small pump it being employed to replenish the gasolene as it is used, this pump being automatic in its operation by reason of a suitable connection to the engine, the connection shown consisting of a pivoted lever 71', adapted to be depressed by a cam h carried by a suitable shaft if, said lever 72 bearing upon and actuating the spring-retracted plunger h of the pump. The desired level is maintained in the cup by means of a suitable overflow-pipe 1, connecting the cup to the gasolene-tank.
Formed in the chamber 6 is a vertical passage j, which connects at its lower end with the gasolene-chamber and at its upper end with the interior of the intake-pipe, this passage being arranged centrally with reference to the intake-pipe. This passage is closed and opened and regulated by means of a suitable cock, which in the present instance consists of a horizontal stem is, extending in through the walls of the gasolene-cup and the intake-pipe and the upper wall of chamber 6,-
its inner end'being tapered and fitted into a similarly-tapered socket intersecting the vertical passage j, this tapered portion being provided with a transverse passage adapted to register with said passage j. is provided with an operating hand-wheel Z at a point outside of the gasolene-cup, and it is held in place bymeans of a suitable gland m,screwed into the casing and bearing against the shoulder a on the stem, this gland being provided with an angular head to permit it to be readily adjusted. It will be observed that the stem is entirely inclosed by a horizontal cylindrical casing 0, formed integral with the walls of the parts through which the stem passes. The stem is limited in its rotative movement by means of a pair of anglearmsp, carried by a collar rigidly, but adj ustably, attached to a stem between the gland m and operating-wheel Z, the extremities of these arms extending inward and adapted to strike against the opposite side of an intermediate lug q, projecting laterally from the gasolene-cup.
It will be observed that the suction created through the intake-pipe by the movement of the engine-piston will create a partial vacuum therein and the pressure of the atmosphere will force the gasolene up through central passage j, sending it up into the intake-pipe in the form of a jet, the volume of which will be governed by the cook or valve, said pas= sage j and its chamber e forming a sort of nozzle. Over the exits of passage j is awire gauze 'r,which will break up the jet partially, and at a suitable point above the wire-gauze The stem is is suspended a spraying-cone 3, this cone betions, preferably inclined with reference to.
the face of the cone, so that the jet will be broken up in fine particles upon striking the cone. The inverted, cone is adjustably supported by means of a vertical stem t, threaded down through the upper side of the intakepipe and locked in its adjusted position by a lock-nut it.
It will be observed that with this simple device the requisite amount of gasolene will be drawn out of the cup at each pulsation of the engine and will be finely sprayed and vaporized and thoroughly mixed with the ingoing air before introduction into the cylinder, this thorough admixture being secured by the peculiar spiral direction the spiral ribs on the cone impart to the ingoing spray, as evident. It will also be observed that the invention is not confined to the specific features of construction shown and described.
Having thus fully described myinvention, what I claim, and desire to secure byLetters Patent, is
1. In a gasolene-cngine, the combination with its intake-pipe, a jet-nozzle supported therein and having its exit end directed inward in the direction of the suction, a gasolene-holder connected to this nozzle, means for maintaining a predetermined level in the gasolenc-holder, an inverted spraying-cone supported in the intake-pipe in the path of the jet and with its apex directed toward the jet, this cone being provided on its inclined face with spirally-arranged ribs, whereby the jet will be broken up and the spray given a spiral motion on its way to the engine and be thoroughly mixed with the air as and for the purposes set forth.
2. In combination with the intake-pipe of a gas-engine, said intake-pipe being provided with a depending branch pipe, a gasolene cup or tank surrounding this branch, a chamber 6 being formed integral with the branch and projecting into the path of the ingoing air and provided with a jet-nozzle, this chamber e being in communication with the gasolenecup, and said nozzle being formed in the inner wall of the chamberecentrally of the intake branch and having a passage j extending from the lower part of chamber 8, below the gasolene-level, up through the upper wall of said chamber 2, a horizontal stemvalve 7; extending in through the walls of the chamber 6 and branch pipe and gasolene-cup and controlling the jet-passage a cylindrical casing 0 surrounding this stern throughout its length, means for maintaining the level of the gasolene in the gasolene cup and chamber c, and a device in the intake-pipe and above the jet-nozzle for breaking up the jet.
In testimony whereof I hereunto afiix my signature, in the presence of two witnesses, this 29th day of June, 1898.
