Specification of Letters Patent.
Patented Sept. 4, 1906.
Application filed Juue' l, 1906. Serial No. 320.133.
To all whmn it may concern:
Be it known that I, GORDON LAND, a citizen of the United States, residing at Oroville, Butte county, California, have invented certain new and useful Improvements in I-Iydropneumatie Elevators or Injectors, of which the following is a specification.
My present invention relates to improvements in hydropneumatic jet elevators or pumps for handling liquids, sand, gravel, and the like.
The object of the invention is to provide a simple and efficient construction in which air not under pressure may be introduced into the center of the jet or injector.
The invention is illustrated in the accompanying drawings, in which Figure 1 is a central longitudinal section, and Fig. 2 a central section taken at right angles to Fig. 1.
Referring by reference-numerals to the drawings, 6 designates the suction-pipe through which the liquid, sand, or gravel is drawn, this suction-pipe being representative of the usual or any desired form of suctionpipe.
9 represents a discharge-pipe, and 7 a Y branch connected at one end to the suctionpipe and having its branches at the opposite end connected to corresponding branches of the injector or jet-chamber S, which in its turn is connected to the discharge-pipe.
4 designates an injector-nozzle for the hydraulic jet, which projects into the center of the chamber 8 axially in line with the discharge-pipe 9 and discharge-throat 5 of the chamber 8, the water under pressure for the hydraulic jet being introduced from a suitable pipe through a jet-chamber 3, made separate from the nozzle 4 and of elbow form, as shown.
The numeral 1 designates an air-pipe which extends up through the elbow or et chamber 3 and centrally through the jet-nozzle 4 and is designed to permit the air at atmospheric pressure to be drawn through the same by the action of the hydraulic jet. This pipe is preferably provided with a check-valve 2 for preventing the escape of water therethrough when the flow of water through the nozzle 4 is cut off or at any analogous time.
Heretofore great difficulty has been experienced in introducing air under pressure in hydraulic pumps or elevators of this character, and wherever air has been introduced it has generally been at the sacrifice of power and efficiency of the main jet. By introducing air in the center of the jet, as above described, I completely change the character of the introduction into the discharge-chamber and the air while being drawn in at atmospheric pressure is placed under pressure in the discharge-chamber, where it is free to es cape without the sacrifice of power.
The et-chamber and nozzle 4 are both carried by a flanged ring 3 which is removably secured by bolts. By disconnecting the flanged ring the parts are rendered accessible, so that a larger or smaller air-jet may be substituted for that previously used.
Having thus described my invention, what I claim is v 1. A hydraulic injector comprising a suction-chamber, suction and discharge pipes communicating therewith, a hydraulic-inj ector nozzle projecting into the chamber, and an air-pipe in communication with the atmosphere and extending into the center of the chamber, substantially as described.
2. A hydraulic injector comprising a chamber, suction and discharge pipes communicating therewith, a hydraulic-injector pipe extending into the chamber and an air-pipe open to the atmosphere and extending centrally through the injector-nozzle into the chamber, substantially as described.
3. In combination, a suction-pipe, a discharge-pipe, a chamber connected to the discharge-pipe and having side branches connected with the suction-pipe, a hydraulicinjector nozzle projecting into the chamber between the side branches and an air-pipe extending through the injector-nozzle, substantially as described.
4. In combination, a suction-pipe, a discharge-pipe, a chamber connected to the discharge-pipe and having side branches connected with the suction-pipe, a hydraulic inj ector-nozzle projecting into the chamber between the side branches, and an air-pipe extending through the injector-nozzle, said airipe communicating with the atmosphere and being provided with a check-valve, substantially as described.
In testimony whereof I aliix my signature in presence of two witnesses.
GORDON LAND.
