ERNEST NOBLE WARD AND FREDERICK JASPER 1N ARD, OF BAXTER SPRINGS, KANSAS,
ASSG-NGRS OF ONE-THIRD TO SAMUEL M. WEST, F BAXTER SPRINGS, KANSAS.
. PNEUMATICALLY-OPERATED PUMP.
To all vii/m 'it may concern.'
Be it known that we,.EnNnsr N. TARD "and Fnnonmcx J. Villino, citizens of the United States, `and residents of Baxter 5 Springs, in the county of Cherokee and State or" Kansas, have made certain new and useful Improvements in P neumatically-Qperated Pumps, of which the ofollowing 1s a s pecication.
l0 Our invention relates lto operated 'pumps and more particularly to pumps of a kind suitable :for deep wells. l
u' More particularly stated,l our invention Lcomprehends a. pump of this general characterand having improved mechanism for enabling the water discharged from the' well l vto control'the admission and discharge of l air usedtorlifting the water. y f eiterencev is made to the accompanying drawing forming a part ot' this specication, I-and in'which like letters indicate like parts.
Q echanism of a pump made in accordance withourinvention. Fig. 2 is a fragmentary section Qn the line 2-2'of Fig. 1 showing a tank forming a part of the apparatus. Fig. 3 is a Idetail showing the valve mechanism Vfor controlling Athe air supp y.
A well casing is shown at 4 and extends downwardly into the ground 5 so as to constitute `in "t is instance the well proper. It should be understood, however, that our mechanism need not be in the well proper as-itcan be Ilocated in anyV suitable opening Y 'inthe ground where a cylindrical casing can beV placedol that water willenter it. Located wit 'in 'the' casing 4 and concentric to f the same is a discharge pipe which is provided with a check valve 7 and with perforations 8. Above the valve 7 and perforaltions 8 is a packin 9 and below the valve another 'packing 10, these packings being air-tight. Avalve 11 'is located below the packing 10 and controls the admissionof wat-er into the pipe 6; The pipe 6 is provided with a portion 13 located above the well and extending downwardly lto a tank 14; This tank is provided with u' check valve 15 which is mounted upon a lpivot 16 and is used fordischarging water rom vthe tank 141i.` .'lhetank` 14 is provided with a guide 17 having the form of a. partition of 'substantially semi-cylindrical form. lVithin the tank 14- andladjacent to the partltion 17 is a float 18 provided centrally with Specification of Letters Yatent. Application ined November as. i912.
pneumaticallyl lFigure 1 is a central section through the' `Fig. 3.
Patented Sept. 9, 1 913. serial No. 733,618.
an opening 19 and extending through this lopening is a guide rod 20. This guide rod carries two collars 2122 each adjustably secured upon it by aid of a set screw 23. The upper end of the guide'rod 20 is piv- 60 otally connected to a bell crank lever 24, the latter being journaled upon a pin 25 and adapted to rock slightly. Connected with the valve 5 for the purpose of opening the same is a pitman 26. The upper end of this p-itman is pivoted to a bell crank lever 27. This bell crank lever 'is journaled upon a bearing 28 and is provided with an arm 29 carrying a pan 30. This pan is directly below the portion 13 of the pipe 6 through 70 which water is discharged as hereinafter described. A pitnian 31 of suitable length is pivotally connected to the upper portion of the bell crank lever 27 and is also connected to a lever 32, the latter being journaled upon a stationary bracket The lever 32 is provided with a number of holes 34C for facilitating the adjustment of the adjacent end of the pitman 31 Z- different distances from the bracket 33. The bracket 33 is 230v mounted upon a pipe 35 used for discharging air as hereinafter described.
'The valve mechanism for controlling the air supply is shown more particularly in A valve chest is shown at 3G and 85 an alr supply pipe at 37. The valve chest 3G is provided with a cylindrical passage 3S and slidably mounted within this passage is a valve pist-on 39 and two pressure i pistons el() and 11. All of these pistons are 90 carried upon a rod 42. The air supply pipefv f communicates with the passage 38. Any'. air Aexhaust pipe is shown at 413 and extends i from the passage 3S into the outer atmos y i phere. The valve chest is provided niita-.95 compartment fifi, and from the latteritwlo corepassages and 46 extend to the.'ends of Athe cylindrical 'passage 38. Two pipe sections 47-48 are connected with a pipe 49 which leads down through the larger pipe 16 and communicates with the interior of the casing 4() as will 'be understood from Fig. 1. The core passagesY 415-46 are cou-p, trollable by gates :B0-'31, the latter being c mnected with' a T lever 52. A pitman extends from this T lever to the bell crank lever 24. The casing pipe 4. is usually of considerable lengt-h and the packings 9- '0 are located some distance apart. The air supply pipe 37 is' connected with an air 110 :a1point just a little below the 'The weightk of the ioat 18'by pu ling upon `most limit of'travel, the
' the saine.
the bell crank lever 24 shifts the pitinan 53 to theleft, according to'Fig. 1, the T levei 52 being rocked `slightly in a clockwise p0- sition. Th'e gate 51 is n ow at -its upperate 52 being in its lowermost position. T ev air from the air supply pipe 37 now passes through the` core passage 45 and presses against the adjacent face of the piston so a's to force this piston to the left, the other pistons, of course, traveling in the same direction. The air supply pipe 37 is now in open communif cation with the pipe section 48, whereas the pipe section 47 is closed by the piston 3i). Air under pressure now continues through the pipe 49I and escapes into the casing pipe 4 at a point just below the pipe 9. The `pressure thuseirerted upon the water in the casing' pipei'4 forces this waterfthroiigh the perforatiens-8 and/jup through the casing pipe 6. Theefwater makes its discharge through theportion ,13 of this pipe and in so doing depresses, the pan 30, rocks the lever 27 and this 'rocking movement closes the valve '15 and also ,pulls the lever 32 so that the pan 32i carried by it rushes against the adjacent lower end of the pipe 35 and closes The watertthus discharged into' the tank 14 fills this tank andin so doing raises the float 18. When the float reaches the approximate upper limit of its travel it lifts the collar 21/which rocks the bell crank;
lever 24. This moves the pitman 53 endwise and causes the 'l'l lever 52 to rock in a contraclockwise', direction according to Fig. 1'. This shiftsvv the relative' positions of the gates .51 and 52 so that the pistons 3i), 40
and 41 -travel to` the right according to Fig.
pipe 37 is now no longer 1. The air supply 49, but
communication with the pipe i /tlie pipe 49 is in open communication with pipe 35.' The casing pipe (5 being now th eniepty and the air above the Water in this pipe being no longer needed, this air escapes through the pipe 35. In doing this it issuesin the form of a strong jet against the pan 32 and thus causes the lever 32 to swing to the fright 'according to Fig. .1. This 'movement shifts the pitman Bland causes the bell crank lever 27 to turn slightly in a clockwise direction according to this figure. The rocking of the bell crank lever 27 raises the pan 30 .into proximity to the lower end of the portion 13 of the casing or discharge pipe 15 and also opens the valve lthe water in the tank 14 now making Aits escape"and when the float 18 reaches" the l'ower limit' of its travel the cycle of operations above described is repeated. The process continues solong as water of. proper depth remains in the wellby closure of the yair supply pipe 37,
construction shown, as Variations may be made therein without departing from the spirit 'of our'invention. Nor: do we limit lourselves tothe 'use of any particular may terials for purposes 'of construction, nor to connnensui'ate with our claims.
