SIPHON WATER ELEVATOR.
APPLICATION FILED DEO.20,1905.
UNITED STATES PATENT OFFIOE.
JAMES NELSON WOOD, ERNEST AUGUST HOEN, AND ANDREW CHARLES MEAGHER, OF RICHMOND, VIRGINIA.
SIPHON WATER-ELEVATOR.
Specification of Letters Patent.
Patented Oct. 9, 1906.
To all whom it may concern:
Be it known that we, JAMES NELSON W001), ERNEST AUGUST HOEN, and ANDREW CHARLES MEAGHER, citizens. of the United States, residing at Richmond, county of Henrico, and State of Virginia, 'have invented certain new and useful Improvements in Siphon Water-Elevators, of which the following is a specification.
The drawing is a side elevation'of our improved elevator.
Our invention consists in a system in which a siphon B, B, and B is used, in which the inletleg B and B and the outlet-leg B may be of the same area or the outlet-leg B may be reduced in' area at a convenient point. On the outlet-leg B is placed a pump G, based, preferably, on the principles of the Giffard injector. At any high point of the siphon we drop a tube C of a propriate length. At a point below thehig est point of the siphon we inclose the end of the tube or intermediate column C in a water-trap I. This Water-tra has on its top a small air-inlet valve J. his tra is alsoprovided at a low point with an out et to the air by a tube K, on which is a check-valve L, that can be lifted only by pressure from beneath it. At any convenient point in the intermediate column C a check-valve F is laced, the purpose of which is to prevent t e return of water from thewater-trap through the intermediate column C when atmospheric pressure is admitted to the water-trap. A vacuum-pi e A leads from the pump G on the outleteg to the top of the water-trap. There is also placed in t e water-trap a float 0, made of any suitable material, that as it is lifted by the'influx of water through the column Cre'aches a point where it'will finallyu set the air-inlet valve at the top. When t e siphon is filled with water in the usual Way that is, by closing the inlet and outlet pipes and filling it with water, either from a hose or any other waythat may be convenientthe inlet and outlet ipes are opened and the siphon flows 'in t e usual wa The intermediate column C obviously ilas been filled with Water when the siphon is filled with water, because the column is in free. communication With the siphon. As soon as the siphon starts to work the head of water passing through the pump G induces a powerfu vacuum in the vacuum-pipe A, which is instantly communicated to the water trap or traps. This causes the check-valve F in the intermediate column to rise, and the water flows from the intermediate column into the water-trap I until it is partially filled. As
the water enters the float O rises until it reaches and opens the inlet-valve J, causing.
atmospheric pressure to enter the trap I. The column of water in the trap subjected to this atmospheric pressure closes the valve F in the intermediate column, acts on the outlet-pipe K of the trap, and lifts the checklished, the air-inlet valve J resumes its seat,
the check-valve L on the outlet-pipe K resumes its seat, and the air that is contained in the trap begins to be drawn out by the continuous action of the vacuum-pump G on the outlet-leg of the siphon. As soon as the condition of vacuum has been restored inside the tra the former operation is repeated. I
he advanta es of this system'lie in its sim licity, in t e rotection of the siphon itse f from air, in t e use of an intermediate column to protect the siphon from the'influx of the air that enters the trap. This intermediate column is also a factor of safety in the event of any temporary derangement of parts in the water-trap itself. In addition to the points iven it is not necessary to confine the water t at passes through the siphon to acting on one pump, Any number of pumps may be use( 'that canbe conveniently operated by the given stream of water. Although in the ex eriment so far carried out a pump such as s own. in the annexed drawin has been used, any pump of general type s own As soon as the trap is such as is due to the Ipresence of air orparticles of air in the water t at enters the inlet. This airthat comesin with the water in minute parts gradually accumulates at any defective ]OlI1tS orhigh places and unless measures are taken to protect the siphon against it willfinally destroy the siphons action, and it will have to be started over again. To overcome this, we provide a tank P, in which a low vacuum will be maintained by means of a small ump using only a part of the Water from t e outlet-leg. The action of this vacuum will be only placed in communication with the weak points of the siphon'that is to sa joints, or high points, elbowsbut constant y removing any incoming or accumulating air, thus making the action of the siphon continuous under all circumstances. We claim that in any siphon there is at the high point a state of tension in the waterthat corresponds to a vacuum; but by means of the vacuumpump we obtain a surplus of power that enables us to overcome the natural suction or natural vacuum of the si hon and draw water from it at this high point. Water can be raised to any height on this principle in successive stepsthat is to say, the water liberated from the Water-trap can be taken and lifted again by means of a si hon similar to that described, and so on inde nitely. On the additional lifts an increased ratio of efficiency will result from the additional head of water-that passes through the vacuum-pump and -while it would probably never be possible to exceed twenty-eight inches of mercury in actual vacuum the capacity of the pumconsidered as to its power and volume, woud be immensely increased.
