WALTER B. MOORE, OF WALLA WALLA, WASHINGTON.

LIQUID-IMPELLING APPARATUS.

Specification of Letters Patent.

Patented June 15, 1909.

Application. led November 4, 1907. Serial No. 400,674.

To allwhom it may concern:

Ide it known that I, NAL'IER B. Moonii, a citizen of the United States of America, and

a resident of the city of Walla Walla, in the county of Walla Walla and State of Vashiiigton, have invented certain new and useful Improvements in Liquid-Impelling Apparatus, of which the following is a specification. My invention relates to improvements in liquid impelling apparatus and aims primarily to provide an improved apparatus of the above character which can be operated in an efficient manner.

A further object resides in the provision of means for normally preventing the ingress of air into the liquid discharge pipe.

With the above and'other objects in view to be set forth, as the description progresses, the invention residesy in the structural features, arrangements and combinations of parts hereinafter described and succinctly defined in the annexedclaims. Referring now to the accompanying drawings in which like' numerals of reference indicate like parts throughout.: Figure 1 is a side view of an apparatus embodying my invention, parts being shown in section. Fig. 2 is a top plan view, and Fig. 3 is a detail view in section, on enlarged scale.

In carrying out my invention, I provide a suitable liquid discharge pipe, as 1, to which the iiuid under pressure is supplied, and at a suitable distance from its lower end, said discharge pipe 1 is provided with an air inlet means 2.

A valve 3 normally prevents the ingress of air into pipe 1, so that column of water from which the strata are to be obtained, as will later be moie fully described, will not be charged with air and filled with bubbles aswould be the case were the air permitted to enter in a continuous manner into the liquid discharge pipe. Val've 3, as now considered, is in the form of a hollow tube or cylinder, being open at both ends and being of such length as to, upon being operated, alternately close the air and water inlet ports.

Water or other li uid to be impelled is supplied to pipe 1 r'om

suitable receivers

4, 4 there being two shown in order that the operation can be a continuous one. Two receivers are however, not absolutely necessary, as'will be readily understood.

The air inlet means 2 consists of a pair of ports, clearly shown in Fig. 1, which are connected by pipes 5,

.communication respective pipe each with a respective receiver at theupperv portion thereof. The water inlet ports 6 are formed in pipe 1 below poi-ts 2 and are connected by pipes 7 to the lower portions of the receivers.

Receivers

4, 4 are provided in their bottom walls with inlet ports 4a through which tiuid enters to fill said receivers, said ports being provided with suitable valves, as 8.

Reference numeral 9 indicates a suitable storage tank, supplied with air under pressure, from which 'a supply pipe 10 leads. Pipe 1() is connected to branch pipes 11, leading each to a respective receiver, and communicating therewith preferably at the upper portions thereof, as illustrated.

A t the juncture of pipes 10 and 11, I provide a valve 12 which is suitably ported to, upon being rocked, alternately establish `between the respective branch pipes 11 and pipe 10, thereby enabling air from tank 9 being discharged [irst into one receiver and then into the other. Valve 12, as now considered, is controlled byfloats 13, slidably mounted on rods 14, in receivers 4, 4', said floats when having lowered a predetermined distance, engaging stops 14,`on said rods 14, and acting as weights lowering said rods. rPhe movement of rods 14 is transmitted to valve 12 through levers 15 'and links 16, the latter of which are connected to arms 17, fixed to said valve.

The ports of valve 12, there being two shown, are arranged toezicli alternately es tablish communication between pipe 10 and a respective p ipe 11, and then each alternately establish communication between its l1 and an exhaust pipe 18.

Pipe 18 is connected with a pair of branch pipes 19 having suitable check v alves indicated at 1.9, which communicate with a double acting air compressor 20, as shown.v

At the juncture of

pipes

18 and 19, a valve 21, controlling a port communicatin with the ati'nosphere is provided (see Fig. 3 By this construction after the water has been exhausted from a receiver, the air in said receiver is drawn into compressor 20, together with a certain amount of air from the atmosphere, admitted through port-controlled by valve 21, and then forced through a pipe 22, provided at 22 with suitable check valves to tank 9. As air is exhausted from the receivers, water will enter through the inlet ports 4 thereof, as will be readily understood.

smaller or lower of said cylinders havingthe l piston 24 therein and being in communication with supply pipe l0 through the medium of a pipe 26 which communicates with cyl-V inder 25 at the lower 'portion thereof. Cylinder 25 is arranged beneath discharge pipe l and is in communication therewith rso as to bear the weight of the water in pipe l.

Now for example, assuming tank' 9 to contain air at 20 pounds pressure, and the ports are arranged as shown, air entering receiver et forces the water therefrom into pipe l up wardlytlirough valve 3 until the weight of column of water in said pipe is substantially equal to the air pressure, then by reason of' the difference in the surface areas of pistons 24, 24', the pressure of the column of water on the larger of said pistons will overcome the pressure of air exerted on. piston 24', and effect the lowering of valve 3. Valve 3 when lowered closes ports 6 and opens the air inlet ports 2, thereby permitting of the air cutting into the sideof the column of water at a suitable distance above its lower end and forcing upwardly the superimposed portion of the column of water. When in pursuance of this operation water is discharged from pipe l, and the weight of the column of water in pipe 1, thereby reduced, air in cylinder 25 will a 24 and the valve 3 upwar ly, thereby openingl ports 6 and closing ports 2. Water entering again through one of the ports 6 fills the lower portion of pipe l to a point above dports 2, when the weight of the water in sai pipe l will again effect the lowering of valve 3, as hereinbefore described. This o eration being continued, pipe l will be li led .with alternating strata of air and water, thereby enabling the lifting of water to great heights with a comparatively small amount of pressure.

I desire to call particular attention to the function of valve 3, the saine preventing air entering discharge pipe 1, until the column of water in pipe l rises to a point above the inlet ports 2. By this construction, when air is admitted into pipe' l it will cut into the side ofthe column of :water and form a solid stratum or piston ofair and lift the water lying thereabove for discharge. If valve 3 was omitted and air allowed to flow in a continuous manner into ipe l, the water about the air'inlets would) be kept in a constant state of agitation, and a loss of efficiency by air assing through the strata of1. water, in the orm of bubbles, would resu t.

It will be understood that by the construction described, the air first forces the water through one ofthe ports 6 into pipe 1 to as ain force piston ters Patent of the United States of America,
