DEEP-WELL PUMP.

Application led July 21,

The object of my invention is to provide a pump capable of raising large quantitiesof water for irrigation and for other purposes, from bored or Artesian wells of great depth, said pump 'being of simple construction, adapted for indefinite extension, and capable of economic operation. In irrigation reclamation fields where, on account of eX- cessivepumping, the water level has been lowered, the favorite centrifugal pumps are no longer available without the trouble and expense of making pits to receive them Iin order to get them near the water. The pumps which followed these centrifugal pumps, namely the single acting cylinders located at different levels in a cased Well are open 1.o the objection` ot insuil'icient ca' pacity to deliver the water the well was able to' supply. The double plunger. pump, Which has taken the place ot these, and in which one plunger operates above another in oppo` site direc-tion, while of greater capacity, is objectionable from an economical standpoint,

yin that| itrequires a costly arrangement of pump head, a double sct of cranks, connecting rods, cross heads, and plunger rods, which lit one within the other. The operation of this type oi pump', especially in -sandy water, has always been costly and annoying, because no means' have been devised to prevent the water and sand from getting inv bctween'the two plunger rods and causing them to 'eut and wear, resulting in the frequent wearing out and breaking of the pump rods, and the consequent breaks in other portions of the pump. Moreover, these pumps are not able to deliver the amount-of water many wells can furnish` 'By my invention, I provide a pump which l may -appropriately cit a multi-plunger ,cylinder Which-avoids all these obyeetions inv that it is capable, by its simple and indefinite extension, of delivering' all the Water 'supplied,.an,d by its construction and Specieaton of Letters Patent.

additional purposes of sustaining the cylinder, and containing and guiding the operating-rods.

2 is a downward extension of the discharge pipe 1, connected with it by a couplingl 3, which is formed with an internally projecting flange 4, upon which rests the head casting 3 of the upper section G of the cylinder, which isthus suspended within the extension 2. A screw ring` 7 holds the head 5 down to its seat on the tlange 4, so that the interior of the extension 2 is not in direct communication with the interior of the discharge pipe 1.

The suspending head 5 ol the cylinder section is formed below'ils top with an annular series oi.' ports 8, which communicate exterior-ly with the space 9 between the cylinder G and thc.extcnsion Q, and interiorly with a port l0, opening through the base ol the head, which port 1() is con- 13 is the upper section of a hollow plunger rod which passes down through the cylinder head, and has connected with its upper end the propelling rod 14. The hollow plungerrod section 13, is connected within' thel cylinder section G tol'a succeeding similar plunu i ger-rod section`15,'by a coupling 1G which has ported extensions' 17 communicating` exvteriorly with the interior of the cylinder and interiorly with the hollow plunger-rod sections.

Upon the upper end of ,the coupling 1G is and having ports 19 made through it. These 'actuated valve Q0.

The water can be taken in` at the end of each cylinder, each of which may be used as single or as double `acting pump. All the plungers can be o jerated by one plunger rod. I

The capacity of the pump is limited only bythe practical liowing velocity of water through the discharge p1pe instead of being controlled by the area of its plunger.

The extension 2 of the discharge pipe, not only-serves to guide and steady the cylinder at its bottonnbut .also serves as a suction pipe in case the water yrecedes below the top of the upper cylinder section 6.x In case, however, that Said. cylinder Sectio-n is at all times suiiiciently snbmergedeven while operating at its maximum capacity, the extension 2 is not necessary.
