PNEUMATIC WATER-ELEVATOR. Y

Specification of Letters Patent.

Patented Feb. 25,1919.

Application filed June 8, 1917. Serial No. 173,531.

To all whom it may concern.-

Be it known that I, FELIX DENIZET, a citizen of the United States of America, a resident of Perryville, in the county of Perry, State of Missouri, have invented certain new and useful Improvements in Pneumatic Tater-Elevators, of which the following is a full, clear, and eXact description, reference being had to the accompanying drawings, forming a part of this specification. Y

My invention relates to an apparatus for raising water by air pressure from wells or other basins and conducting it to any point to which it may be desired to make delivery. The invention has for its object the production of a simple apparatus of this kind which is automatic in operation, and which is of such simplicity as to be not liable to become inoperative or impaired by long continued use.

Figure I is a vertical section, partly in elevation, of my water elevator.

Fig. II is an enlarged side elevation of the mechanism for controlling the vertical movement of the submerged tank of my water elevator.

Fig. III is an elevation of the parts shown in Fig. II viewed from a point at a right angle to the point from which the parts in Fig. II are seen. Y Y

Fig. IV is an enlarged section on line IV-IV, Fig. III, through the controlling valve of the elevator.

In the accompanying drawings, 1 designates an upper horizontal anchor beam or stay which serves to position a frame comprising vertical rods 2. The rods 2 extendto the bottom of the well or basin B from which water is to be elevated and have fitted to them at their lower ends a bottom stay bar 3 provided with a vertical guide 4.

5 designates a tank submerged in the water in the well or basin B adapted to partake of limited upward and downward movements to provide for the actuation of certain controlling elements, as will hereinafter appear. The tank 5 is in part directed during its vertical movement and held from turning by a non-circular stem 6 at the bottom of the tank fitted to the guide 4. A horizontal stop bar 5' secured to the vertical rods 2, and further held from upward connecting said cross bar to the bottom stay bar 3, serves to limit the upward movement of thetank 5.

The tank 5 is provided with a water inlet 7, controlled by a valve 8 which opens automatically when the pressure in the basin B is in excess of the pressure in the tank 5, but is held closed by pressure in the tank 5 when the pressure in the tank is in excess of that in the basin.

9 designates a vertical section of pipe fixed to the tank 5, said pipe section being disposed partly within and partly above said tank. The pipe section is telescopically fitted to a vertical water discharge pipe 10.

11 designates a U-shaped hanger depending from a horizontal supporting bar 11 secured to the rods 2. A shaft 12 is journaled in the legs of the hanger 11 and has fixed to it a pinion 13, in mesh with a rack 14: secured to the pipe section 9.

A 3-way valve C located at the lower end of the hanger 11 comprises a housing 15 secured to said hanger and a ported plug 16 in said housing, which is fixed to the shaft 12 and is rotatable therewith. The 3-way valve C serves to control the delivery of air under pressure from a conducting pipe .17 to the interior of the tank 5, and the escape of air from said tank, as will hereinafter appear.

The air under pressure may be delivered from an air compressor or other" suitable source of supply through the conducting pipe 17 leading to the housing of the 3-way valve 0, and when the plug of said valve is in the position in which it is seen in Fig. IV, the air in the pipe 17 will pass to a pipe 18 leading to the interior of the water delivery ipe 10, said water delivery pipe preferably including a union 19 through which the pipe 18 enters the pipe 10. The pipe 18 extends downwardly in the water delivery pipe 10 to the lower end of the latter, and preferably leads to the exterior of said pipe within the tank 5 and then upwardly in said tank to a point near the top of the tank, as seen in Fig. I, so that the air passing through the pipe 18 may be discharged above the level of water in the tank 5. Y e

The housing of the 3-way valve C is provided with-a duct 15, which is open to the atmosphere and which is adapted to be placed in registration with the pipe 18 when Y 20 designates a tri arm fixed to the shaft 1.2 by which the 3-Way valve C is operated. This trip arm is preferably in the form of a sector and is located at the end of said shaft opposite to that at which the 3-way valve C is located. At one side of the trip arm :isa trip pin 21, which is movable in an arc of a circle and is adapted to be shifted with the trip arm from one side of a vertical line drawn through the axis of the shaft 12 to the other side ofsaid vertical line.

;22 designates a vrockable controller pivoted intermediate of itsends at 23 to the hanger 11, said controller comprising an upper arm provided with a counterbalance weight 22 and a lower arm bifurcated to produce divergent legs 24 and 25, each of which -is adapted to be engaged by the trip ;pin 2 1.on the trip arm .20.

-26 designates a detent device pivoted to the'hanger ,11 ;.at 23, said device being provided with .a pairof spaced pendent arms 27 adapted to engage the triparm 20, when said armis .ineither of its extreme positions. Atthenpper endof thedetent device 26 are ;arms,28 provided with abutments 29 and 30 between which the upper arm of the rock ableeontroller 22is operable, and which are adapted to belengaged by said upper con- ,trollerarm when it is rocked to and fro on its point f pivotal support.

'Thehanger 11 is preferably formed with an elbow .1:1. locate d at its lower end, which extends transversely of and straddles the pipe section 9. Thiselbow serves as a sup port for a ;roller 11 located opposite the "pinion 13, between which and said pinion ztlle pipe sectionQ isdirected in its vertical .movements. 7

In the practical use of my automatic waterelevator theoperation is as follows: When ,the tank .5 is supplied with water to be withdrawn therefrom through the discharge pipe 10, said tank is submerged, as seen in Fig. and the inlet valve 8 occupies a closed position. At this time the plug 16 pf the valveC is in the position in which it s seen in IV,-so that there is communic ation between . theair pipes 17 and 18 and air under pressure :maytherefore be delivered t0 the-interiorof the tank 5 to exert pressure against the .water in said tank and force it through the delivery pipe 10 to the point at which it is desired to deliver the water. WVhile water is being discharged from the tank through the discharge pipe, the valvelplug 16 ismaintained in the position in which itgisseen in Fig. IV, due to the ,holding influence of the detent device .26, ,the arm 2 o which a t ga st he .trip ,arm 20 and is held thereto by the weighted :QQHtlTOllBP 22 lying in engagement with the abutment 30 of the detent device 26. The weighted upper arm of the controller 22 constitutes a counterbalance and in full lines Fig.

isshifted to the basin B against the tendency of the tank 5 to float in the water in the basin B when the tank has become. Jartially emptied by removal of water there rom through the discharge pipe 10, and all of the parts of my water elevator will retain the positions shown in Figs. I, III and IV, and in full lines Fig. II, until the tank has become sufliciently emptied to commence to rise in the basin B, due to its buoyancy. Upon the tank having been emptied t0 the degree just referred to, it rises and carries with it the pipe section 9 and the rack 14 thereon. As a consequence of the upward movement of the pipe section 9, the rack 1 1 operates to rotate the pinion 13 and the shaft 12 to which the latter is fixed, whereby the valve plug 16 is turned to close communication between the air conducting pipes 17 and 18 and establish com munication between the pipe 18 and the vent duct 15 of the valve housing 15, so that air may be vented from the tank 5 to the atmosphere.

During the rotation of the shaft 12 to change the position of the valve plug 16 of the valve C, the trip arm 20 rotates with said shaft toward the right hand relative to the position in which it isseen in Fig. I, II, and the trip pin 21 carried by said arm strikes the leg 25 of the controller 22 while said trip arm is moving to the dotted line position, Fig, II, and in consequence of this movement the controller dotted line position, Fig. II, and shifts the detent device 26 to the dotted line position, So that the valve plug 16 may be completely shifted from the position shown inFig. IV, and the tank-5 may rise to the limit of its intended upward movement. In shifting to the dotted line position-shown in Fig. II, the controller 22 strikes the abutment 29 of the detent device 26 and causes the leg 2 7. 0fsaid detent device to engage the lefthand edge of the trip arm 20, thereby providing forthe temporary dectentionof said trip arm and the valve plug 16 in ,the positions to which they have been adjusted.

It will be readily understood that when the parts are in the positions last recited the tank 5 is in an elevated position, and inasmuch as the compressed air pressure in the tank has been relieved there is opportunity for the pressure of the Water in the to open the inlet valve 8, which therefore opens and water is admitted to the tank .to fill it. As the tank becomes filled it settles in the water in the basin until git reaches the limit of its downward movement, and there is resultant readjustment .of the shaft 12, valve plug 16, trip arm .20 and partsopera'ble by said trip arm to their original positions. As will be apparent, when the trip arm returns to its original position the stud 21 strikes the leg 24 of the controller 22, and said controller is tilted from thedotted line position, Fig. II, to the full line position, Fig. II, with the result of causing the detent device 26 to again engage the trip arm 20 and hold it from movement until the tank 5 again moves upwardly by flotation. An important feature of my water elevator is the connection of the air conducting pipe 18 to the water delivery pipe 10, and the support of the air pipes 17 and 18 and the air controlling valve C, so that these parts will remain stationary when the tank 5 and other moving parts partake of movement. Such arrangement avoids the use of flexible pipes such as rubber tubing, which has heretofore been used in water elevators of the type to which my invention belongs, and which become unserviceable after a short time.
