PUMP.

SPECIFICATION forming part of Letters Patent No. 270,900dated January23, 1883.

Application iled August 12, 1882. (No model.)

appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specifica- My invention relates particularlyr to that class of pumps known to the trade as suction andlift(combination) pumps,in which water is raised from wells of various depths by plungers and valves.

rlhe object of my invention is to simplify and cheapen and at the same time to render more ei'ective the operation of such pumps.

My invention consists ot' a novel apparatus' for raising the water, which is accomplished by the use of particularly-constructed valves and plungers, in combination with certain other devices, such as will be hereinafter described.

Referring to accompanyingdrawings, Figure l is a vertical sectional View of myentire ap paratus. Figs. 2, 3, 4, 'and 5 are detached views of parts ot' Alower `valve, l\"ig. 2 being the top flange, Fig. 3 the clapper, Fig. 4 the bridge having guide for upper end of clapperstem, and Fig. 5 the bottom iiange with lugs and slots, and having` g'uide for lowerend of clapper-stem. Figs. 6, 7, S, and 9 are detached views of myA improved plunger, Fig. 6 being section ot' plunger proper, showing the bolt that secures the bridge'to it, Fig. 7 being said bridge; Fig. 8 is clapper, and Fig. 9 is a vertical elevation ofthe plunger proper. l Fig. 10 is a view of an improved clapper which may be used in the place of the one illustrated by Fig. 3, iF preferred. Fig. ll is a side ele vation of one of the plungers.

My improved ,plunger consists of F, the plunger proper, and having f, the guide for lower end of clapper-stem, at its foot; G, the

clapper, consisting of a, the stem, and b and b, respectively, the upper and lower ianges, having theleather packing c between; H, the

bridge, having e, the guideof the upper end of steine ofclapper G; I, the bolt securing the bridge H toits position in plungerproper, F,the head resting in aslot at the top ofthe forked portion ot' said plunger proper, F, and the nut upon the head of bridge H, the point of the bolt fitting into a circular opening therea't, so as to admit of the free play of the nut upon the thread of the bolt I. g is leather packing secured Ato its position over circular .foot ot' plunger F by 111e ends ot` the forks of bridge H pressing thereon, and kept tightly to their place by screwing down the nut upon bolt I. The circular foot ot' plunger F contains the guidej' of lowerend ot' stem, a, of clapper (if. My improved lower valve consists of body A, the lower flange, A', having the four lugs carrying bolts securing it to E. B is the valve-seat, which rises to a suitable height above the body A, which has the slotsx made through its flange y for the bolts z to catch in; B, the upper flange; '0, the clapper, consisting of flanges b and b, bolted together, with the leather c between, and stem a, the leather c `resting upon seat B; D,-the bridge, the roofof which has a round hole as guide for upper end of stem a of clapper O, the body A having the guide l forthe lower end of said stem a.

Having described the various parts, I will now set forth the manner of use, together with my method ot' producing a continuous stream of water. i Any suitable style and size of piping is inserted in the well and secured to the coupling ot' body A, which is secured to platform E (the coupling` otl ange Aresting in an opening of platform E) by the bolts ot' the lugs 'A'. By this method of fastening the body A to the frame E the lower valve and apparatus above mentioned may be removed by removing the bolts e, and thus taking oft' the body A without disturbing the pipe in the well. 'Ihecomplete clapper G is then placed in position by inserting the lowerend of itsstem a into guide d of body A. Bridge 1) is then placed in position, the circular hole inits summit taking the upper end ot' stem a of clapper C and acting as its guide. B, the upper flange attached t0 thelowerend ofapumpcylinder,is then placed in position, and secured there by bolts passing down through slots of flangeA.' My improved plunger as first above described is then iii- TOC serted in the cylinder, and being properly connected with the usual plunger-rod the pump -is then ready for operation by the usualmethod as afsingle-action pump; but should it be desired to use that portion of my invention as above suggested,by which a continuous stream of water may be raised, another section of cylinder connected to upper end ofthe rst-men tioned cylinder by iianges J (having a bridge,) and J must 'be employed and another of my im proved plun gers placed therein, and the two plungers connected and operated by the following device: The upper plunger has the rod N connected toit, and is operated'in'the usual manner; but thelower piston iscaused to move downward by the combined help ofthe weight of the water above it and the springsO while the upper piston is being raised upward, and

the lower piston is drawn upward as the up! per piston descends through the force that is exerted upon it by the pressure of the upper piston on the rod M. This rod M has its upper end forked, so that the upper piston will 'press squarely upon it, and is guided in its vertical movements by the guide I), which forms a part ot' or is secured to the flange J.

To thelower end ot the rod M is secured thecord, wire, or chain L, which passes .up over the pulley K, and then has its other end fastened to the upper end of the lower piston. Vhen the upper piston is forced downward, it strikes upon and forces the rod M downward, thereby drawing the lower piston upward through the cord, wire, or chain L. When the upper piston is raised upward, the combined weight of water upon the lower piston and the pull of the coiled springs C) draw and force the lower piston downward, thereby forcing the rod M through the cord, wire, or chain L upward.

By this above device and method a continuous stream of water is kept flowing from the nozzle ot' the upper section of the cylinder whenevcrthepumpingapparatus,as described, is set in operation.

My devices may be applied to an ordinary forcepump by adding the necessary packing vand piston at the head of the upper section of cylinder.

In place ot' the clapper (l of the lower valve may be used,if preferred, a clapper, C', as shown iu Fig. 1.0, which consists of a clapper-stem, a',

with top flange, having secured to it by bolts a forked guide, b2', with leather c between it and the ange. This device fora clapperIconsider more certain in its operation, being less liable to wear and lose its position.

WVhen it is desired to remove the clapper G from its position in the plunger, the nut of boltI is loosened on its thread, and thus permits the easy removal of clapper G. When it is desired to change from the double action to the single action, the driving-rod ot' the upper plunger may be sufficiently shortened, and thus prevent the plunger upon its downward stroke from reaehin g the head ofthe propeller M, which will cause lower plunger to lie dormant at the bottom of the lower section ot' cylinder.

Having thus described myinvention, I claim and desire to secure by Letters Patentl. IThe combination of the body A, having the ange Af, valve-seat B', and ange y, having the slots w, with the platform E, flange B, bridge D, and valve, the parts being secured together substantially as shown. l

2.y The combination ot' plunger F, provided with the guide j', and having a recess iu its side to receive the packing g, the bridge H, and bolt I with the valve or clapper, substantially as described.

3. rIhe combination of the upper plunger, a vertically-moving rod, l\[,a lower piston,and a cord, wire, or chain, which connects the rod and lower piston together, and a guidefor the cord, the rod being entirely disconnected from the upper piston, substantially as set forth.

4. The combination of the upper plunger, a vertically-movingrod,a connecting cord, wire, or chain, and a guiding-pulley, the lower piston or plunger, and the springs O, substantially as specified.

5. rThe combination ot' the upper plunger, a vertically moving rod, a connecting cord, wire, or chain, a guiding-pulley and a suitable guide therefor, and the lower plunger, substantially as shown.

In testimony whereof I affix my signaturein presence of two witnesses.

SURN JACKSON.
