T0 all whom t may concern:

Be it known that we, lEnNns'r N. Wann and FREDERICK d. WARD, citizens of the United States, residing at Baxter Springs, in the county of Cherokee and State of Kansas, have invented certain new and useful Improvements in Pumps, of which the following is a specification.

Uur invention relates to pressure operated pumping systems, of the general type that embody a partially or wholly submerged pumping barrel or shell with means to introduce pressure into the barrel and to eX- haust the same therefrom, and has particular reference to' improvements in apparatus designed to control this introducing and exhausting of pressure to and from the barrel.

An important object of the invention is to provide apparatus of the above mentioned character, whereby pressure, such as compressed air, will be introduced into the submerged barrel or shell and exhausted therefrom, at the proper interval, so that said barrel will be completely lled with and emptied of the water or other fluid to be elevated. n

A further object of the invention is to provide apparatus of the above mentioned character, embodying adjustable means whereby the intervals at which the pressure is introduced into and exhausted from. the submerged barrel, maybe varied, as may be required under theparticular conditions.

A further 'object ofthe invention is to provide apparatus of thegabove mentioned character, which is wholly automatic in operation, strong, durable, and convenient in use.

@ther objects and advantages ofthe in` vention will be a parent during the course of the following escription. p

its opposite ends with pipes 6 and 7. Connected with the pipe 7 through'thelmedium of an elbow 8 is a pressure inlet pipe 9,hav ing a valve structure 10 connected therein, preferably a balanced globe valvestructure. Connected with the pipe 6 through the medium of an elbow 11 is a pressureexhaust pipe 12, having a valvestructure 13 con- .nectedvin the same, preferably a balanced globe structure. l These valvestructures 10 and 13 are operated by valve stems 14C and, 15 respectively, having their ends arranged between longitudinally spaced strips or bars 16, and crnnected therewith by bolts17 or the like, as shown. Allt is thus seen that the valvev structures 10 'and 13 are simultaneously operated, one being closed as the other is opened. v

Connected with the pipes 9 and 12, preferably below and adjacent the valve struetures 10 and 13, is a preferably *horizontally arranged bar or support 18, having a preferably vertically swinging shiftin lever 19, pivoted thereto, as shown at 20. his shifting lever is arranged between the strips or bars 16, to swing longitudinally thereof, and is adapted to engage with the ends of the valve stems 14: and 15 or other elements carried by the strips 16, to edect a reciprocatory movement of such strips.`

rl`he numeral 21 designates a bell-crank lever, as a whole, comprising a longitudinal arm 22 and a transverse'arm 23, such bellcranklever being connected with the bar 18 preferably by means of the bolt or pivot 20. Connected with the free end of e transverse larm 23 is a suitably stifl'l retre coil sprin 242, the opposite 'end of which is connecte ywith the upper er yend of the shifting lever 19, as sh llrom the fore-y going, it will be seen dan wn the longitudinal arm 22 of the bell-crank lever occupies its lowermost osition, the transverse arm 23 thereof wlll be disposed upon the right of the ivot 20, whereb the spring 24: will q l y swing the shifting lever 19 to the right, this movement'of the shifting lever edecting a movement of the strips 16 in the same direction, said lever engaging a stop 25, preferably -rovided with shock absorbing means 26. here are two of these stops, which are identical, the samel being Aconnected with the valve struc- Itures .10. and 13, as shown. When the longitudinalt` arm 22 is swung toits upper poloo lll@

sition, the transverse arm 23 is swung, to 'the left of the pivot 20, as indicated upon Fig. l, whereby the spring -24 quickly swings the shifting lever 19 tothe left, for

effecting a corresponding movement of the strips 16, the lever 19 engaging the stop 25, as is obvious.l

Meansare provided to swing the'longitua dinal arm 22, of the bell-crank lever 21 up and down in a substantially vertical plane, thepsame comprising a link 27, connected with the outer end of the longitudinal arm 22, as shown. This link has its upper end pivotally connected with a reci rocatory carriage 28, mounted to slide longitudinally upon an up'standing or vertical cylinder or shell 29, as shown. Connected with this carriage 28 'are upwardly extending rods 30, suitably connected with a cross headl, which is rigidly connected with a pistonrod 32. This piston-rod is mounted to reciprocatgJ .within the cylinder 29 and operates through an aperture in the cap or head 33, closing the upper end thereof, as shown. This aperture is preferably formed larger 'in diameter than the piston rod 32 whereby air may freely ass into and vout of the upper portion ol) the cylinder, to prevent the lcreation of vacuums in such upper por- 30 tion. Connected with the lower end of the piston-rod32 is a piston 34 mounted toreciprocate within the cylinder 29.

Connected with the lower end of the cylinder 29 is a T-coupling 35, the lower end of 35 which is connected with and closedby a plug 36, connected with and closing one end of a T-coupling 37. This T-coupling is connected with a piple 38, connected with the coupling 5 throug the medium of an elbow 39. Connected with the T-coupling 35 and in communication therewith is a pipe 40, the opposite end of which is connected with the coupling 5 and in communication with the interior thereof. Connected in the pipe 40 is a check-valve 41 of any well known or preferred type, re erably a ball checkvalve. This chec valve ermits the passage of compressed air in t e direction indicated by the arrow but prevents the same from passing in a reverse direction. Ar-

ranged near the check valve 41 is a cut olf valve 42, connected in the pipe 40, and

adapted to be manually operated to regulate v the passa e of the air through the pipe 40.

Connecte with the pipe 40 by means of a T- coupling 43 is a by-passv pipe 44, having ,a check-valve 45 connected therein, of any well known or preferred type, preferably a ball check-valve, adapted to permit of the passage of air in the direction of the arrow, ut to prevent the-passage of the same in an opposite direction. Connected in the bypass pipe 44 to one side of and near the valve 45 is a cut off valve 46, adapted to be manually operated for regulating the passage of the exhaust air through the by-pass pipe 44.'

As more clearly shown in Fig..2, the pipe 38 extends exteriorly of a building 47, with- .barrel 48 is `preferably vertically arranged,

and the lower end thereof is closed by a bottom 50, having inlet openingsV 51, formed therethrough, adapted-to be covered and uncovered by upwardly opening check-valves 52, as shown. Connected with the lower end of the barrel 48 is an outlet pipe 53, to exjtend to any desired point at which it is desired todischarge' the water or other fluid. as The outlet pipe 53- is provided near its connection with the barrel 48 with an upwardly openn check-valve 54, to prevent the returno the water 'or other uid from the pipe 53 into the barrel. 90

The operation of the ap aratus is as follows: Assuming that the iferent parts of theapparatus occupy the position shown in Fig. 1, lthe valve structure 10 wllbewopen while the 'valve structure 13 will be closed. 95 Compressed air will now pass through pipe 9, valve structure 10, pipe 7, couplin 5 elbow 39, pipe 38, and into the upper en of the barrel 48, to force the water or other fluid therefrom, the samepassing outwardly through pipe 53. Some of this compressed air also passes from coupling 5 through pipe 40, the amount thus assing being regulated by adjusting the va ve 42. From the pipe 40 the compressed air passes into the lower end of the cylinder 29, to elevate the piston 34 therein, at a desired rate of-speed, which may be determined by adjusting the valve 42. This upward movement of the piston 34 moves the carriage 28 upwardly, which in turn swings the free end of the longitudinal arm 22 of the bell-crank lever upwardly. When the horizontal arm 22 of the bellcrank lever is moved to its uppermost position, the transverse arm 23 will be shifted to the left to assume a position uponA the opposite side of the pivot 20. When this Atakes place, the sprin 24 quickly swings the lever 19 to the left, or opening the valve structure-13 and closin the valve-structure 10. This preferably ta es place when all of the water has been expelled from the barrel 48. The valve structure 13 beingnow open, compressedV air will exhaust from the upper end of the barrel48, passing through -pipe 38, elbow 39, coupling 5, elbow v11, valve structure 13 and through exhaust pipe 12 to the atmosphere. This exhausting of the air from the barrel permits of the water filling the same, preparatory to the next expelling 130 maarre operation, The compressed air in the lower end of the cylinder 29 is also exhausting to the atmosphere, whereby the piston 34 will be lowered at a desired speed, it being understood that the piston 34 moves downwardly by gravity, due to its weightand the weight of the carriage and associated elements. Pressure now passes from the lower end of the cylinder 29 Vthrough coupling 35, the outer end of pipe 40, T-couplig 43, by-pass pipe 44, the inner, end of' the pipe 40, coupling 5, pipe 6, elbow l1, valve structure 13,

and through exhaust pipe l2 to the atmosphere. It is obvious that the speed at which the piston 34 will descend is controlled by adj ustingthe valve 46. When the piston 34 moves downwardly sufficientlyv the longitudinal arm of the bell-crank lever is again moved downwardly, whereby the transverse arm 23 thereof will be disposed upon the `right of the pivot 20, the sprin 24 ag in suddenly-swinging the shitting gever 19 to the right, to open the 4inlet valve 10 and close the outlet valve 13. This operation may be repeated indehnitely.

it is to be understood that the form of our invention herewithl vshown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be re sorted to without departing from the spirit ot the invention 'or the scope of the subjoined claims.
