LIQUID-CONTAINER AND VALVE MECHANISM THEREFOR PARTICULARLY APPLICABLE FOR USE IN WATER AND LIKE ELEVATORS.

To all whom it 'may concern:

Be it known that I, ALBERT EDWARD Hon- DER, a subject of the King of England, residing at London, in England, have invented certain new and useful Improvements in Liquid-Containers and Valve Mechanism Therefor Particularly Applicable for Use in Vater and Like Elevators, of which the following is a specification.

This invention relates to improvements in liquid containers and valve mechanism therefor, and is particularly applicable for use in raising liquids, such as water, sludge, sewage, and the like.

An important feature of this invention is the combination with two or more liquid containers of means for automatically and successively connecting them to a source of fluid-pressure for emptying them and of means for subsequently reducing the pressure so that liquid can be forced into the containers.

Other features of this invention will be evident from the following description taken in connection with the accompanying drawings, which illustrate the preferred constructions of apparatus employed in carrying this invention into effect.

In the drawing the iignre is a diagrammatic sectional elevation of two containers with their valve-mechanisms.

Like letters indicate like parts throughout the drawings.

A and A1 are two containers. The liquid is supplied through an inlet conduit B and passes through to the containers through openings C and C1. A valve D controls the lpassage of the liquid to the container A and a valve D1 to the container A1. These valves are mounted on a common spindle D2 and they are so arranged that when one is opened the other is closed. Vhen the liquid is emptied from the containers it passes through either the openings C or C1 to outlet conduits E or E1.

Gas under pressure is led through the conduit or pipe F and can pass to either the container A or A1 through pipes Gr or G1 respectively. The passage ot' the gas through the pipes G and G1 is controlled by valves H and H1 mounted on a common spindle H2. These valves are so arranged that when one is closed the other is opened and preferably the amount of movement of the valves is Specification of Letters Patent.

very limited so that it is practically impossible for both valves to be even partially open at the same time. The pipes G and G1 are led nearly to the bottom of the containers A and A1 respectively. The tops of the containers A and A1 are provided with airoulet valves I and I1 respectively, these valves being adapted to close when floated upward by the liquid in the containers.

The operation of the apparatus is as follows lVith the containers empty and the valves in the position shown in the drawings, liquid supplied through the conduit B would pass through the valve D and into the container A. The conduit E it is assumed is connected toY a conduit reaching to a height above the containers or is closed in some manner so that the liquid does not pass out of the conduit E. The valve I is open so that the container gradually filli with liquid until reaching the float of the valve I the latter is closed. Compressed gas is then supplied through the conduit I` and this escaping through the pipe C1 to the atmosphere, closes by its rush the valve H1 and consequently opens the valve H. The compressed gas then passes through the pipe G and bubbles up through the liquid, forcing the liquid out of the container A through the conduit E. The pressure of this liquid closes the valve D and opens the valve D1 whereupon the liquid is able to pass from the conduit into the container A1. The valve H having been opened the valve H1 is closed so that the container A1 is filled in exactly the same manner as described above in connection with the container A.

lVhen either the container A or the container A1 is being emptied, the valve I or the valve I1 respectively is kept closed by the pressure of the gas. The valve I1 is illustrated in the drawing as being in the closed position, but with the container empty as shown this would not be the case; it is so illustrated merely to indicate the position it occupies when both containers are operative and the container A is in process of heilig filled and the container A1 in process of being emptied. Considering, for eX- ample, the container A as being empty and about to be filled, the valve H being closed by the major pressure in the conduit F, the water rising in A will entrap a column of air in the pipe Gr, which by the time the y container A is filled will be under a pressure I equal to the head of water above the lower Veither container is completely emptied.

j' end of the pipe. When the time comes for the valve H to open, the operation is made instantaneous by the column of air in pipe G expanding and thus eXpediting the ac- 1 tionof the rush of air past H1.

Vith the two cylinders in operation the valves H and H:L are operated by the rush of gas which occurs at the moment that The operation of the valves H and Hl is,

K' ashas just been described, aided by the pressure of the gas entrapped in the pipes siderable height above the containers as illustrated. s

VOne of the chief advantages of this invention is that there is no moving mechanism within either container.

Obviously various modifications may be l made in the method of carrying this inven- 1 tion into effect.

y Vhat I claim as my invention and desire to secureby Letters Patent is l l. In a water elevator the combination of al source of liquid supply J, a conduit B connected thereto, two containers A A1 each connected at the bottom directly to the conduit IB through a valve, a source of fluid pressure7 conduits G G1 connected to each other and to the said source of fluid pressure and said containers, valves H H1 in said conduits G G1 arranged one on either sidel of the junction of the conduits G G1 with the conduit connected to the source of fluid pressure, a spindle H2 connecting the said valves I-I H1 and a conduit K from the bottom of each container leading up to the level of discharge.

2. In a water elevator the combination of a source of liquid supply J, a conduit B connected thereto, two containers A A1 hav-l ing openings C C1 at the bottom each connected directly to the conduit B, valves D D1 between the conduit B and the openings C C1 respectively, a spindle D2 connecting said valves D D1, a source of fluid pressure, conduits G G1 connected to each other and to said source of fluid pressure and said containers, valves H H1 in saidconduits G G1 arranged one on either side of the junction of the conduits G G1 with a conduit connected to the source of fluid pressure, a spindle H2 connecting said valves H H1 and a conduit leading from the bottom of each container up to the level of discharge.

3. In a water or the like elevator the combination with a container of a fluidpressure conduit reaching nearly to the bottom of the container and an air-trap formed by the fluid-pressure conduit and the liquid in the container.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
