INVENTO BY OQaW W ATTORNEYS WILLIAM G. CROSS, OF SENECA FALLS, NEW YORK.
MOTIVE-FLUID MIXER- FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Patented J une 25, 1912.
Application filed October 24, 1908. Serial No. 459,333.
T 0 all whom it may concern:
Be it known that I, lVILLIAM Gr. Cross, of Seneca Falls, in the county of Seneca and State of New York, have invented a certain new and useful Motive-Fluid Mixer for Internal-Combustion Engines, of which the following is a specification.
My invention has for its object the production of a motive-fluid mixer for internalcombustion engines, by means of which the amount of combustible fluid to be mixed with air in the formation of each charge of motive-fluid is positively controlled; and the invention consists in the combinations and constructions hereinafter set forth and claimed.
In describing my invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.
Figure 1 is an end view of a vaporizer embodying my invention and connections thereto to a movable part of the engine to which it is connected. Figs. 2 and 3 are sectional views taken at right angles to each other, a mixing chamber being shown in Fig. 3. Fig. 4, is a sectional view similar to Fig. 2 showing the valve in a different position.
My motive-fluid mixer comprises means for measuring the amount of combustible fluid, as a gas, a liquid hydrocarbon or alco- 1101, to be mixed with air in forming each charge of motive fluid, and for cutting off the air and fluid to be mixed with the air at the same time, so that the proportion of air and fluid to be mixed is always the same irrespective of whether the charge is a large or a small one.
As here illustrated my motive-fluid mixer is constructed to vaporize a liquid as a hydro-carbon or alcohol; and it includes a delivering device comprising a case 1 and a movable valve 2, in the case. The case 1 is preferably of cylindrical form and is formed with laterally extending bossesor nipples 3, 4, designed to be connected, respectively, to the cylinder of an internal-combustion engine and the outlet conduit of the fluid supply reservoir, the nipple 3 being shown in Fig. 3 as connected to a conduit 30 which constitutes a vaporizing or mixing chamber. The nipple 3 is formed with an air outlet passage 5 and with the outlet passage 6 for the liquid to be vaporized, and the nipple 4 is formed with an inlet passage 7 for the liquid to be vaporized, said inlet passage 7 being here shown as located about diametrically opposite to the passage 6. The case 1, as here shown, is formed in two sections, each section being formed with flanges 8 en gaged with each other and held together by clamps 9 passing transversely through the flanges 8, and by dowel pins 10 provided on one flange 8 and extending into openings in the other.
The valve 2, is formed with an air-passage and with a transfer passage for the liquid to be mixed with air. These passages are movable into and out of registration with the passages 5, 6 of the case during the formation of each charge, and as here shown said valve is journaled in the case and oscillates therein, and is formed with an axial air passage 11 communicating with the outer air and having a radially-extending branch 12 movable into and out of registration with the air passage 5 of the case; and said valve 2 is also formed with an angular transfer passage 13 extending therethrough and opening through opposite sides thereof, one end of said passage being movable into and out of registration with the inlet passage 7 for the liquid to be vaporized and the other end of the said passage being movable into and out of registration with the exit passage 6 for such liquid, one end of the passage 13 being out of registration-with the passage 7 while the other end is in registration with the passage 6 or vice-versa. The valve 2 is oscillated, by a movable part of the engine, not illustrated, to which this vaporizer is attached, and, as here shown, it is provided with a rock arm 14 connected by a link 15, to a movable partof the engine not shown, this link 15 being slidably connected at 16 to the rock arm 14 in order that the extent of movement of the valve piece may be adjusted in order to vary the volumes of the charges, by shifting the link 15 toward and from the axis of the valve. When the arm 14 oscillates to its fullest extent, the passage 12 will register squarely with the passage 5 while the transfer passage 13 will register squarely with the passage 6, and when the passages 12 and 13 are out of register, respectively, with the passages 5 and 6, the transfer passage 13 registers with the inlet passage 7; and when the extent of the move-. ment of the arm 14 is lessened, said pas sages 12 and 13 will not register exactly with the passages 5 and .6, and 7 ,so that a smaller charge is formed containing the same proportion of liquid and air as the larger charge.
Although the nipple 3 in which are formed the air and liquid outlet passages 5 and 6 is here shown as extending upwardly, and the nipple 4: in which is formed the inlet 7 for the liquid as extending downwardly, it isaobvious that said passsages may be arranged in any desired positions, their positions being dependent in some instances upon the amount of fall between the supply tank and the vaporizer.
In operation, during the formation of each charge, the valve moves in one direction so that the transfer passage 13 of the valve 2 registers with the inlet passage 7 of the case for permitting the liquid to flow into the transfer passage; the valve then moves in the reverse direction carrying the transfer passage 13 out of register with the passage 7 and bringing said transfer passage 13 and the air passage 12 into registration, respectively, with the air and liquid outlet'passages 6 and 5.
Owing to the fact-that the valve shuts off the air and combustible fluid passages during the formation of each charge, back fire is prevented.

A motive-fluid mixer formed with a transfer passage for the fluid to be mixed with gas to form a charge of motive fluid and with a passage for the gas, said passages having inlets and exits, and means operable once during the formation of each charge for opening the exits of said passages and closing said exits simultaneously,
