WILLIAM L. MORROW, OF LOS ANGELES, CALIFORNIA.

PUMP.

Specification of Letters Patent.

Application led February 24, 1915. Serial No. 10,237.

To all whom t may concern.'

Be it known that I, WILLIAM L. MoRRoW, a citizen of the United States, residing at -Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pumps, of

which the following is a specification.

This invention relates to improvements in pumps, and particularly pumps adapted to force water from deep weels by air pressure.

It is an object of this invention to provide a pump in which an .air piston acts upon a column of liquid in the well casing to discharge the same from the casing.

It is another object of this invention to provide a pneumatically operated pump with an air compressor which continuously forces air into a reservoir serving to supply air to an air piston for forcing the liquid from a well.

It is a still further object to provide a pump operated by pneumatic pressure with a reservoir, and a relief valve mechanism for intermittently admitting compressed air to act as a piston upon a volume of water,

then cutting olf the source of air pressure and connecting the air piston chamber to the atmosphere.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which:

Figure 1 illustrates my pump mechanism installed in a well, with the well and parts of the mechanism shown in vertical section. Fig. 2 shows the timing mechanism for my `air relief valve. Fig. 3 is a vertical section through the foot valve.` Fig. l4 is a horizontal section taken on line 4 4 and with the vconduit of the valve cage partly broken away.

' More specifically, 5 indicates an air pump casing provided with pump cylinders 6 and v7 disposed vertically and having a cooling ment with cranks on crank shaft 15. On the end of crankshaft 15 is secured a driving pulley 16. The inlet ports for the air compressor comprise open ports 17 and 18 in the walls of the pump cylinders and are disposed at a point adjacent the upper end of the piston stroke. At the lower end of pump cylinders 6 and 7 are mounted check valves 19 and 20 carrying valve stems 2l 23 and 24. Guide sleeves 23 and 24 are se- .cured to caps 25 and 26 and are preferably integral therewith. Caps 25 and 26 close openings 27 and 28 in lower wall 29 of the air reservoir 30. Disposed over sleeves 23 and 24 are spiral springs 31 and 32 abutting the ends of the valves 19and 20, land at the other end the caps 25 and 26 respectively. Such an air valve construction permits ready access to the valves and removal of the springs as caps 27 and'28 may be removed andthe springs l31 and 32, as well as ratenteaoct. 1o, 1916.

valves 19 and 20 removed through the apertures 27 and 28.

In the well is mounted a well casing 33, and mounted upon the surface of the ground at the upper end of the casing 33 are discharge troughs 34 and 35. Connected to the lower wall 29,0f reservoir 30 is a short pipe 36 to which is attached a valve casing 37 having nipples 45 and 46 disposed at 90 and 180 degrees thereto.

Attached to the valve casing 37 by means of nipple 46 and in line with the pipe 36 is member 39 preferably by threads, is a valve i seat 42 whichy tightly` lits within the well casing 33, sealing the same. Valve seat 42 is provided with a port 43 controlled by valve 44. Valve casing 37 is provided with an air relief port connected to nipple45 leading to the atmosphere. Mounted within valve casing 37 is an oscillating valve 47 having a bore 48v diametrically disposed therein, and a second bore radially disposed and at right angles thereto. Valve 47 .is fiXedly secured to a stub shaft 48 having on its end and spaced from the casing an arm 49, yMounted on shaft 48 between arm 49 and casing 37 is a spiral spring 50 secured to the arm and to the valve casing, such that it tends to hold the arm in one position. yLaterally extending from shaft 48 is a pin 51 .disposed to engage a sto-p pin 52 which is secured to valve casing 37. Disposed toengage arm 49 isa cam member 53 ixedly secured to a shaft 54. Shaft 54 is mounted in bearings on theframer of the air compresser, andV carries at its end a beveled gear 56 which meshes with a beveled gear 57 mounted on a shaft 58, disposed at right angles to shaft 54 and carried in bearing 59 'secured to the reservoir 30; At the opposite end of shaft 58 is a beveled'gear 60 meshing with a gear 6l which is secured to the cran 1shaft 15.

.into the `conduit 38,and acts upon the column of liquid therein toforce the liquid downward. Valve 44 is seated by thepressure and seals the lower part of the well casing from the upper. The compressed air acting as a piston Vupon the top of the watercolumn in conduit 38 forces the liquid Kout of conduit 38 and into the annular space,

causing the liquid therein to rise and overflow into troughs 34 and 35. During this dischargeoperation crank shaft 15 hasbeen continuously revolving and through meshing gears 61, 60, shaft 58, gears 57, and 56, and shaft 54, cam member 53 is caused to revolve and move arm 49 with the valve 47 into position at 90 degrees to that shown in `Fig. l, wherein the bore '49 is connected to bore 48and'thence through pipe 46 to the atmosphere, relieving the pressure on the water. At the same time pipe 36is sealed by the valve 47. Water enters through valve 44'and around it into conduit 38, and also into the chamber surrounding conduit `38. The ball 44 rests on the top of valve cage 39, but does not Yclose conduit 38.

The timing of valve 47 is determined by factors 4which include the'di'mensionsof the chamber between pipe 38 and casing 33, the

pressure and velocity, so that the inertia of thecolumn of water assists in discharging the latter and drawing in a new increment of water. As there. are no valves or obstructions in the discharge chamber, the opening ofthe air valve permits the water remaining in the discharge Vpipe to return, then oscillate back toward the discharge, at which time vthe (ai-r valve admits compressedrair to further i discharge liquid. The discharge chamber between pipe 38 and casing 33 thus forms a play chamber inwhich the .water may oscillate.
