To all wwm 'it may eoncem:

Be it known that I, Rounn'r E. L. Homme, a citizen of the United Stntee; residing et Aurora, in the county ol" liano und Stute of lllinoisJ have invented eertuin new und uneul Improvements in lunips; of whieh the following is n speeiiienl'iou. reference being had to the aeeoulpunyiup?` drawings.

illy invention relates-to pumping. .zppzij rutns; und Imrtieulurly to pumps designed for use in rzlisinpl walter .troni deep wells olf Smell here where the water doer-1 not rino suiiieientlly neur to the suri'aue to he drztwn out by ineens ol :l suction pulnp.

lt has for its ohjeet to provide u new und improved double-:loting pump so constructed and operutinpr ur; to deliver Huhstuntiullv :i uniforni 'volunie ol" wnter on either the u'p or the down stroke; elmo to' provide a pump adapted to he' plnved in the bore. of the wel] ln'elferuhly helow the level of the water therein und so eonntrueted that the vulves und pis-Lou '.inu v ezusily he drawn out ot the well Aio'r repuirs without removing the puntp piping und working hui-rel from the well. l aeeolnplieh these objects :is illus-l trated in' the drawings and hereinni'tzer described.

that I regard as new is set forth in the claims.

425 indicates a collar fixedly secured on the piston-.rod below the packing-box 31,

either upward or downward. Preferably, I

C employ cup-shaped disks 55 of leather in and l-l indicates :i similar collar secured on the lower i'iiston-rod l below the packing- 'box 3f). 'lhe object of providingl thelziper valves and valve seals, alicve described, and

providing the piston rods with the collars` 43 and -ii is lo pei'iiiit the rady removal. ot' the piston rods. piston aiul valve cages. Obviously, when the piston rods are raised the collars 43 and l1 will strike the packing boxes 3l and 3f) from below, therebv li't'liiig the valve cages from their seats and en- 4 abliiig the parts to be witlidraii'n l'i'om the well. rlfhey may also be readily replaced and will automaticalll 'Scali themselves properlyY when lowered i"1ito pi'oper position.

45 indicates a valve-cage at the upper end of the piston-rod 2t) and preferably secured thereto b v being y crewed thereupon. xaid valve-cage carriesl a ball-valve 'lt seated at the upper end ot' the piston rod 29 and acting as a checkr'alvc to prcventthe downflow of water therethrough. As shown in Fig. l. the upper end ot' the vvalve-cage l5 is provided witlra screw-tlireadcd boss 47 for the convenient attachment thereto ot the rod used in withdrawing the piston 'from the well.

48 indicates the piston, which is fitted inl the cylinder 15 and is connected at its upper andlower ends, respectively, with the piston rods 2S) and l2 in vthe manner hereinafter described. As best shown in Figs. l and 2, the piston 4S is provided with a central passage 4f) with which the upper piston-rod 2.() communicates. The lower end of said passage l!) opens laterally and communi; cates with a transverse passage 50 which' opens into the cylinder 15 below the piston, as shown in Figs. l and 5. Said cylinder is also provided witli\ one or more vertical passages 51, the lower ends of which coinniunicate with the lower piston-rod 112, as shown in Fig. 2. .'lhe upper ends of said passages 51 extend through the upper end of the piston, as shown in Fig. Q,- and are normally closed by a. valve-disk 52 which v rests thereupoii, being yicldizigly held down in place by it spring 53 between' rsaid disk and the collar/13, as shown in Figs. 1 and 2. lt will thus 'be seen that water may flow upward through the lower piston-rod 42 and passages 5l, entering the cylinder l5 above tbe pistou` where it: will be held b y the checkvalve 59..

5l indicates pat-kine' between the piston is of such character as to pack the piston and the cylinder when said piston is moved lthe 'water will be held above the connection with metallic rings 56, which hold the packing in place. Rings 57-58 are secured upon one end of the piston so that the pai-king may he compressed as desired or removed when'nccessary.

The operatioiris as tollow s:-Assuming the piston to be below the level of the water in the cylinder 15, when the piston is raised piston by the check-valve and will be lifted as the piston moves up, flowing through passages )5 and above the valve 26, which will be lifted by the iipwardly-moviiig body ot' water. The lower portion ofl the pipe lb will therefore bc filled with water, which `will be held therein by means of the valve will lill the cylinder 15 below Vthe piston,-

either flowing in by gravity or being drawn up .by suction as the piston rises, and will be held therein by means of the checkvalve 8S, which drops as soon as the upward flow ot' water ceases. The piston being then moved downward, the water below the piston will be t'orced up through passages'50 and 49 through the vupper piston-rod 9.9 to the pipe lll. passing the valve lli. which is li't'ted by the pressure of the upwardly-flowing water. It will thus be seenk that when the piston moves upward the water in the cylinder 15 above it is discharged into the pipe 16, while when the piston moves downward the vater belowit in the cylinder 15 is in like m'anner discharged into'the i e 1G, and as these volumes are substantial y equal it follows thafa practically uniform flow of ,water is securedfIn practice the working barrel or cylinder 15 isl placed a considerable distanceperhaps a hundred feet or morebelow the surface of the ground and preferably below the normal level of the water in the well, and the valvecaLe `l5 is connected 'by a rod with'some suitable reciprocating mechanism for actuating it'. y Q

By the construction described I provide an apparatus which may readilybe' placed in or removed `from tlie'well, and one which provides for delivering a practically continuous and uniform volume of water in ani-up- 'ard direction. I .also avoid the use pf tortu'ous water passages, as-the passages'"inmy appa ratus" are substantially straight andare eonliiiiious in an upward direction, S0 ,that there isless resistance to the'upward flow of water, thereby increasing the efficiency of the pump.

I wish it to be understood that while I have described my specific form of apparal tus with a considerable degree of particularity my invention is not restrictedto the details of the constructioii shown and delI l) sel'ihed, eee t in sofar. as thea;- are spesaidupiston around said central passage, saideially 'elaiinei as it includes .generically the subjeet-niatter of the broader elainis. t f
