Speolfication of Letters Patent. Patented D017; Application filed December a, 19.10. swarm. 595,510.
"To all whom it mag concernl'.
- Be it known that I, FRANK J. OLEA'RY, a citizen of the United, States of America,
residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Ejectors, of which the following is a specification, reference being accompanying drawings.
This invention relates to that class of ejectors which are intended to be operated by fluid pressure to lift water or other liquids and the present improvement is in-.
tended to form an improvement on the common form of lifting ejectors whereby it will operate \more efliciently and economically with water power of low pressure such as generally exists in the water supply of cities and which is ordinarily not sufliciently high to obviate the necessity of priming the e ector i or provide 'it with a hose extenslon on its discharge end to permit of self priming without using an excessive amount of water.
With my improvement I overcome the difficulties and produce an ejector better adapted for use as a substitute for a pump as n removing water from excavations and as a household article for emptying bath or Referring to the drawing A is the hollow body integrally formed with a suction arm B and a discharge arm C, both of which may be suitably screwthreaded for pipe connection or be provided with corrugations to allow hose to slip over and be clamped thereto as better adapted for household puroses. p E is the inlet nozzle for the motor fluid, it
is threaded into the body A and, may be' provided at its outer end with screw threads to fit water taps or iron piping. For household use, a hose coupling member D is had therein to the.
sleeved thereon for connecting it readily to penstocks. The nozzle E tapers diminishingly from the intake to near the opposite end and extends beyond its greatest point of contraction with a gradually enlarging bore. The nozzle E projects into the suction .chamber F formed by acylindrical enlarge ment of the body and communicates with the suction arm B. The body is conically con tracted at the point where it surrounds the discharge end of the nozzle and forms a tapering annular throat G leading from the suction chamber into the discharge arm.
The discharge arm is 'provided with a bulbous enlargement H communicating with the nozzle and with the suction chamber that of the outlet end of the discharge arm and diametrically within the bulbous en largement at right angles to the axis of the nozzle is located a bar'J of triangular cross section and with the point of the triangle presented toward the nozzle.
In practice the motor fluid operatin the e ector has a straight path provided or it and the force of the stream in passing through the neck portion I will entrain air from the suction chamber and create a suction for lifting the water. If the discharge arm were unprovided with the bulbous enlargement containing the bar J, its capacity for lifting would wholly depend upon the volume and force of the stream passing through the discharge arm to fill up the same and prevent back flow of'air through the discharge arm into the suction chamber.
This is the reason why the common form of lifting ejector is ineflicient and uneconomical for many uses where it has to depend for its motive power upon water of low pressure.- j I By providing the discharge arm with the bulbous enlargement and with the bar J, the stream in pressing through the bulbous enlargement is split in striking the bar and a portion of the stream is thrown against the 1nner wall of the ,bulb without materially decreasing its velocity and as a' consequence the space in the bulb fills up and maintains a volume of water of even pressure therein which seals the suction chamber. The device thus acts as a bafiie to prevent the back flow .of air from creeping into the suction chamber and the capacity of the ejector for through a short cylindrical neck portion I, the diameter of which is slightly larger than thereby greatly increased.
' surrounded by the suction chamber, of a discharge arm at the end of the suction chamber in alinement with the nozzle, said arm being-provided with a bulbous enlargement communicating with the suction chamber and nozzle through a short cylindrical portion of the discharge arm and provided with a triangular bar extending diametrically within the bulb at right angles to the discharge arm andwith the apex of the bar opposite to the nozzle.
2. In a lifting ejector the combination with the cylindrical suction chamber rovided with a laterally extending inlet arm and with the tapering inlet nozzle for the motive fluid concentrically surrounded by the suction chamber, of a discharge 'arm at the end of the suction chamber in alinement with the nozzle, said arm being provided with 'a bulbous enlargement communicating with the suction chamber and nozzle through a short cylindrical portion of the discharge arm of larger interior diameter than that of the portion beyond the enlargement, and a triangular bar in the enlargement placed diametricall across thereof and with the apex of the ar opposite to the nozzle.
3. In a lifting ejector, the combination with the suction chamber provided with a lateral inlet arm and tapering inlet nozzle for the motive fluid concentrically surrounded by the suction chamber, of a discharge arm at the end of the suction chamber in alinement with the nozzle, and provided with a bulbous enlargement communicating with the suction chamber through a short cylindrical portion of the discharge arm of larger interior diameter than that of the portion beyond the enlargement, and a bar extending diametrically wlthln the bulb at right angles to the discharge arm.
In testimony whereof I afiix my signature inpresence of two witnesses.
