INJECTOR.
SPECIEICATION forming part of Letters Patent No. 436,932, dated September 23, 1890.
Application filed April 29, 1890. Serial No. 349,948. (No model.)
T0 all whom it may concern:
Be it known that I, DANIEL BEST, a citizen of the United States, residing at San Leandro, Alameda county, State of California, have invented an Improvement in Injectors; and I hereby declare the following to be afull, clear, and exact description of the same.
My invention relates to animproved apparatus for injecting liquids; and it consists in the combination, with a jet-nozzle, of an inlet supply-pipe of peculiar construction.
Referring to the accompanying drawings for a more complete explanation of my invention, the figure is a.longitudinal section of the outer casing and jet-nozzle, with a view of the interior supply or inlet pipe, showing half of it in section.
A is the jet-nozzle, through which steam, air, or gas under pressure is admitted, and B is an exterior casing, into one end of which this nozzle is fixed. At one side of the casing, near the nozzle, is an opening or passage C for the admission of water. To the oppo site end of the casing is connected the pipe or passage D, through which the water is to be conveyed to any desired point by the momentum caused by the velocity imparted to it by the discharge from the jet-tube A. Between this passage D and the jet-tube A and in line with it is a peculiarly-shaped pipe having different diameters or sections, as shown at E, E, and E The smallest section E, which is nearest to the nozzle A, has a sort of bell-mouth opening, into which the nozzle A discharges, and at the opposite end this section is expanded, as shown at F, s0 as to connect with the next section E of larger diameter. This expansion F is shown in the present case as diverging or flaring like a bell-mouth, and through it a number of holes or perforations Gr are made. The next section E is in like manner expanded or enlarged, as shown at F, and is -likewise provided with holes G, opening into its interior from the inside of the Outer casing B, into which the water is first admitted.
H are screw-threads formed upon the exterior of this tube, (shown in the present case at the point between the sections E and E and they fit in corresponding screw-threads I in the interior of the casing B, and by means of this device this peculiarnozzle or pipe may be screwed up or down and adjusted with relation to the j et-nozzle A.
The operation will then be as follows: The jet of vapor being disoharged through the nozzle A with great Velocity, and water being admitted through the passage C into the casing B, will also enter the first section E, and the momentum acquired through the Velocity of the jet and the weight of the water will cause it to be discharged through the'pipes E, E, E and D. A certain proportion of water will be drawn in through the holes Gr around the periphery of the enlargement F, and this water being driven by the steamjet through the section E another portion of Water will be drawn in through the openings G around the periphery of the enlargement F to be carried on through the section E and the pipe D. Asmany of these sections of increasing diameter with the intermediate openings or holes may be made as will be found most desirable, and the object is to admit the water in small quantity to the first section, where it is first acted on by the steam or vapor jet, and then, as the body acquires a certain momentum, to admit an additional quantity of water at the next series of holes, which will be more readily carried onward on account of the momentum already acquired by the body of water admitted through the first openings. In this manner I am enabled to work the injector with more certainty and satisfaction than when the whole body of water is admitted at one point, and the momentum must all be acquired at the point of the first impact of the steam-jet upon the body of water.
The successive aldditions to the body of water gradually increasing it to the full amount desired are features of my invention.
The device here shown is also useful as a blast apparatus.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
An njector consisting of a casing having a jet-nozzle fixed at one end and inline With the axis of the casing and a discharge-pipe connected with the opposite end, an inlet-passage adjacent to the jet-nozzle, in combina tion With the pipe formed in a single piece and upon the exterior of this pipe, Whereby and in sections increasing in diameter from the latter may be adjusted within the casing one end to the other and forming shoulders and With relation to the jet-nozzle, substanor offsets at their points of j unction, a belltially as herein described.
