Since a continuous flow of air passes upwards through the hell it will be readily seen that an equal flow will continue throughout the length ot the npcast pip e. this flow contin ues to act as an annular cushion preventing skin friction between the jet and load w ater and the side walls of the pipe.
Another advantage lies in the fact that the contracted portion of the column may vary in length or in position within the up cast pipe according to variation of the velocity ot' the jet water and the load without meeting with any obstruction such as would prevail, were a choke fitted.
Should it be desired to use the elevator for aerating water for drinking or any other purpose, air may be forced under any desired pressure through the outlet orifice 12 surrounding the jet, which would produce a complete occlusion of the water raised by the air projected therefrom.
\Vhat I claim as my invention is:
l. A hydraulic elevator comprising an upoast pipe having an. upper discharge opening and a lower inlet opening adapted to be set above the surface of the matter to be elevated so as to provide for the entrance of air to form a cushion between the inner surface of the pipe and the matter being elevated therein, and means adapted to induce an upward current. in the upcast pipe, said npcast pipe having parallel sides for an appreciable distance above the inlet opening.
3.. A hydraulic elevator for load water and its solids comprising an upcast pipe having an unrestricted bore. a. discharge out lct and a load receiving bell adapted to be set slightly above the loadwater level so as to permit atmospheric air to flow into said bell to form a. cushion between the inner surface of the pipe and the column of water passing upwardly therethrough, a water jet below the water level and aligned axially with the upcast pipe through which power water is adapted to be projected upwards into the. pipe to raise the load water and its solids for discharge through the discharge outlet.
3. A hydraulic elevator for load water and its solidscomprising an upcast pipe having a discharge outlet and a load receiving hell spaced above the surface oflthe load water to permit atmospheric air to freely enter the lower end of the bell to form a film or cushion between the inner surface of the pipe and the load water passing upwardly theretlirough, a water jetazv'ially aligned with the upc t pipe through which )owcr water is adaptedito be projected I upwar into the "pipe to raisethe load water and its solids through the discharge utlet, and means for introducing an annular ppiiow of air between thepower water jet and the load water when entering the upcast pipe, said up flow being at atmospheric pressure or less.
4. A hydraulic elevator for load water and its solidscomprisiug an upcast pipe having adischarge outlet and a load receiving opening spaced above the surface of the load water to permit atmospheric air to enter between the load water and the inner surface of the pipe, a submerged water jet axially aligned with the upcast pipe for in ducing an upward flow therein and to cause the elevation of the load water and its solids, an air chamber surrounding the jet and having an outlet orifice concentric there with, and means for supplying air to the chamber for discharge through the outlet orifice. v
