GASOLENE-GAS MACHINE.

SPECIFICATION forming part of Letters Patent No. 575,901, dated January 26, 1897. Applicationlled January 2, 1896. Serial No. 574,024. (No model.)

To ctZZ whom it may concern:

Beit known that I, WILLIAM MCKNIGHT, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Gasolene-Gas Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the lettersand figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in gasolene-gas machines, and has for its object to provide an effective machine for generating gas from gasolene-oil.

The invention has specific reference to means for governing the flow of air to the carbureter, and said invention has a further reference to the construction of the carbureter, as will be more `fully hereinafter described `in the specification, taken in connection with the accompanying drawings, of Which- Figure lis a side elevation of the entire apparatus. Portions of the connecting-pipes are broken off. Fig. 2 is an enlarged longitudinal Vertical mid-section of the air-governor. Fig. 3 is a mid-sectional view of the oil-feeding mechanism. Fig. 4C is an end elevation of the same, partly in section. Fig. 5 is a top plan view of the carbureter, and Fig. 6 is a mid-sectional View of same.

plied with air by an air-motor E. The latter is of Well-known construction, therefore does not call for a more detailed description herein. Airis forced into the governor D through 5 5 a pipe 4 and passes thence to the carburetor C through a pipe 5.

F designates a mixer, into which gasolenegas is passed from the carbureter C through a pipe 6 and out to the point of consumption 6o through a pipe 7.

Referring now to the specic construction of the mechanism for feeding the oil to the carbureter, attention is directed to Figs. 3

ce designates a float attached to a bar cl/ that is pivoted at one end to a".

b designates a valve stem or rod having its upper end tapering and forming a needlcvalve in connection with a valve-seat b', pref- 7o erably constructed of Babbitt metal and se `cured in the discharge endof the pipe l. The

valve-stein b is constructed of non-corrosive material, preferably aluminium. The lower end of said stern or rod b is attached to the bar a.

c c designate guides projecting from the interior of the cut-off tank, loosely inclosing the rod b and serving to keep the Valve end in line with the seat b. valve-seat b above the valve, so that the valve moves from below, the said seat is prevented from clogging up by accumulations lodging in and around the sides of the cavity or seat.

d designates an inclined oil trough or guide mounted on the valve-rod and free from contact with other parts.

d' is a second oil-guide placed on an incline, substantially as shown. This guide d has its upper end projecting under the trough d and 9o its lower end secured to the interior of the cut-off tank just below the exit to the pipe 2.

It will be understood from the foregoing description that there is an uninterrupted flow of oil to the carbureter C and the cut-off tank B through the pipes 2 and 3 until the oil in both the cut-off tank and the carbureter reaches a common level, at which time the oil in tank B raises the float a and closes the Valve,

the carbureter. rod is but slight.

The movement of said valve- By thus placing the 8o ci designates a uniony on the discharge end of the pipev 1 provided with strainers a4, consisting of wire-gauze or other similar mesh, for the purpose of straining the oil that enters the carbureter.

Referring to the specific construction of the carbureter, attention is directed to Figs. 5, 6, and 7, upon which H and H designate pans, of which there may be two .or more, placed one on the other and the joining edges riveted and made air-tight. Each of these pans is provided with a plurality of division-strips e, rigidly attached to the top and bottom of the pan and providing a series of openings e, that afford communication from one end of the pan to the other in a circuitous manner, as indicated by the arrows.

f designates a plurality of transverse strips arranged between the strips c. These latter strips f afford means for securing a suitable quantity of vegetable fiber, hemp, or similar material g, which is laid in strands across the top of each of said strips, substantially as is Shown in Fig, 7.

H designates the uppermost carbureter-pan. Oil is introduced thereto through the pipe 2, the said pipe entering the top, side, or at any suitable point. The oil so introduced passes throughout the length and breadth of the pan H and down to the next lower pan H through the overflow-spout h.

As shown in Figs. 5, G, and 7, 7L' designates a transverse strip or dam lying across the entrance to the spout 7i, the object and purpose of which is to prevent the lighter oil, or that on the top, from entering the spout h. The arrow projecting under the dam 7i in Fig. 7 indicates the passage of the oil below the surface. This introduces to the lower pan H the residuuin, which passes into the tank B. It will be understood that the oil never attains a height on a level with the upper edge of the dam It. Therefore said oil will not flow over the top of the dam, but the oil below the surface will pass under said dam, as indicated by the arrow in Fig. 7. The air is introduced to the upper portion of the lower pan through an opening 8, into which the air-pipe 5 is tapped. The air becomes impregnated with the oil and vapor and passes to the other extreme end of the tank H', where it passes upwardlythrou gh the spout 71, to the upper tank H, thence through said tank, and out through pipe 6 to the mixer F.

An auxiliary air-pipe!) connects with pipe 5 and with the mixer, by means of which the gas coming from the carbureter may be subjected to a furthersupply of air in the mixer. The gas generated from the oil when the latter is first supplied to the carbureter is sometimes richer than is desirable. Therefore by subjecting said gas to a further mixture of air in the mixer it will reduce the same to a proper consistency. 4

The next feature of my invention is the airgovernor, `and in describing the same reference is made to Fig. 2.

The cylinder D may be mounted upon the pump E or in any suitable place and has in its interior a vertical valve-cylinder j, into the bottom of which the pipe t from the pump is tapped. The bottom of the cylinder D is water-tight and contains a supply of water substantially to the height shown for the purpose of fioating an air-drum K. Attached to the center of this drum is a rod K', the lower end of which projects through an opening t' in the upper end of the cylinder j and has a ball-valvej, which closes said opening t'.

s designates rollers which are mounted on the drum K and come in contact with the inner side of the cylinder D. These rollers maintain the air-drum in a true vertical position and lessen or avoid undue friction between the parts. The air-pipe 5 projects through the bottom of the cylinder D up into the interior of the air-drum to a point above the water, substantially as shown. As air is forced by the pump through the pipe t into the interior of the drum K it passes out through the pipe 5 to therearbureter. The air entering the interior of the drum K in eX- cess of the amount passing int-o the pipe 5 will gradually elevate the drum until the valvejl closes the opening t, thus cutting off the admission of air and stopping the pump.

It will be seen from the foregoing specification that the supply of air and gasolene to the carbureter is controlled by the machine itself, so that when once the apparatus is properly connected up and placed in an operative position but little attention is necessary, and none beyond keeping the reservoir A filled and the pump wound up. The cutoff tank B and the carbureter may be drained when necessary through pipe lO.

Having described my invention, I claim In a gasolene-gas machine, the combination with an oil-reservoir, a carbureter, and a cutoff tank having a comm unication at its upperv I end with said reservoir, and a communication at its lower end with said carbureter, of a float attached to a lever having one end pivoted to theinterior of said tank, a needlevalve mounted on said lever at a point between the said float and the pivotal point of IOO the lever, the said valve adapted to control R.
