This invention relates to certain improve ments in the kind of pump described in Letters Patent No. 131,644, dated September 24, 1872, and granted to these applicants, It. White and D. Moritz.

The obj ect of the present invention is, rst, to improve the arrangement ot the valves, their construction, and their location in the valvechambers, iu such manner that the .valve chambers may readily be reached, the valves removed for repair or inspection, andeasily replaced.

Another object Of the invention is to improve the construction of the plunger or piston, to improve the means of connecting the operating -lever With the plunger-rod, to provide against the detention of Water Within the pump during cold Weather, and consequently against the danger of freezing up parts of the pump; and to also provide for the proper eollection ofthe drip-water which may bc discharged iiom the pump, or any parts thereot', so that the drip may not intert'ere with the locality in which the pump is put up.

The invention consists in an improved manner ot placing and constructing the valves, improved arrangement of anti-freezing channels and cock, improved manner ot' connecting the handle by a link Ivith the plunger-rod, and in an improvement in the means of holding the pin that .joins said link to the pistoi'l-rod; also, in imprm'ements in the frame or bed ot' the pump, and in a new construction ot' plunger or piston, all as hereinafter more full y described.

The. let-ter A in the drawing represents the frame or bed ofthe pump. lt is made of cast metal, or other suitable material, and preferably raised on legs, as shown. lt is made a nearly Hat bed, b, which is supported by said legs. This bed is surrounded by a projecting ledge, d, Which serves to prevent drip-Water from flowing down along the sides or end ot' the bed, except Where. the ledge is interrupted, and leads into the depression or cavity e, in which all the drip-water of the pump is collected, and from which it may be discharged through a suitable aperture into a suitable receptacle. From thc bed project, also, saddlepieces ff, which constitute the direct supports for the pump-cylinder B. This pump-cylinder is intimately connected with the suction-1 i pe (Y, which projects downwardly through a hole, g, ot' the bed b, and which is threaded to receive a nut, l1., beneath the bed b, as shown in Figs. 2 and 3, so that by such nut h the pump-cylinder is firmly drawn upon the saddles f, and held in place on the frame A. The pump-cylinder i-s also intimately connected with the valvebox l), which, by a horizontal partition, '17, .is divided into an upper and a lower compartment, the lower compartment being, by a vertical partition, j, further divided into two sepa- 1ate chambers, land 1n. The upper compartment n, above the partition i, is continuousthat is to say, although there is, or may be, a vertical partition therein, yet such partition is perforated, so that in reality but one single compartment, n, exists. The discharge-pipe E ot the pulllp collnects with the llpper compartment n of the valve-box, while the suctioupipe C connects, by a hollow branch or chamber, o, which is clearly sllowll ill F ig. 3, with the two lower compartments I alld m. These lower compartments also connect by suitable open` ings alld passages with the ports that lead into the respective ends ofthe pump-cylinder B.

The holes wllicll lead from the supply-chamber 0 into the cllalllbers I m are closed by valves F alld F. The partition i has also two holes, which connect the cllalnber n with the cllambcrs l alld m, respectively, alld whicll are closed by valves (lr The pump operatioll is tllat of every ordinary plnnpwitll respect to the said valvesthat is to say, when the plunger is lnoved in the direction of the arrow sllown in Fi 0. 2 the valve F will be opened alld water sllcked illto the cylinder behindthe piston the valve (lr will be closed by the suction created ill thc chamber I the valve F will be closed by the pressllre of water discharged by the pistoll illt-o the chamber m, and by the salne pressure the valve G will be pllslled open, so that the water lllay, fronl the cllalnber m, be forced through the chamber n into the discharge-pipe E. When the motion of the piston is reversed, the valves F and (l are opened, and the valves F and (l' closed, all of which need not be further delnonstrated.

The valveswhich weclloose toelllploy aretiat plates, as sllowll ill Figs. 7, 8, alld 9, ot' a size suflicient to cause them to close the openings l leneatll and they are made of lnetal or other suitable material of sutticient weight to callse them to close the openings, unless suction or pressure is applied to opell them. Each of these platevalves has at the outer end two projecting lugs, p p, wllich are ill lille with each other, as shown ill Figs. 7 and 9, and preferablyv of cylindrical form. For the reception ot tllese lugs, recesses or llotches are eut into the edges of the walls and vertical partitions ot' the valve-box D, said recesses being marked q ill Figs. 2 alld 3. The valves are introduced between tlle ends alld upright partition of the valve-cllamber, bllt the lllgs p will ollly elltcr therecesses q, and will therein constitute pivots whereon the valves are tllrlled ill their npward and downward play. We deem this con struction of valve alld their combination with the valve-box, that has the recesses q, all inl portantfeature ot' our invention, as it enables us, whenever the face-plate 1l ofthe valvebox is removed, to readily withdraw the valves and as readily replace them. Each ot' thel valves has one or lnore projectin g lugs or stops, r, wllicll, ill the raised position, strikes the face-plate H, and prevents the tilting of the A valves to a greater extent tllall maybe desired.

The face-plate H, which is bolted or screwed over the opell side of the val vellox, is provided with four holes, s t u c, as clearly sllown ill Figs. 3, 4, and 5; bllt the lower hole V maybe omitted. These holes lead illto a cylilldrical or slightly conical chamber, I, which is formed on l ply chamber o ot' the pump. AJ by its handle is tllrlled to bring its aperor fastened to the outer side'ot sad face-plate Il, alld which receives a hollow plug orcxlck, J. This cock contains apertures s t u r', which correspond, alld are respectively ill lille with the apertllres s t u c of the face-plate, alld which all lead into a hollow passage or cavity formed ill the cock J, as indicated ill Fig. 3. The upper passage s of the face-plate communicates with the cllalnber u, the lower passages tu communicate with the chambers I m, respectively, while the lowerlnost passage r, if used, communicates with the water-sup- VVhen the cock tllres s' t u c ill lille, respectively, witll the apertures stu r, the water contailled ln the cllalnbers I, fm, and n will How into the hollow cock J, alld tllellce, through the openings fu r,

`back into the supply-pipe. The central part ot the cock J, which communicates with the apertures s' t' u r' is at or near its upper elld opell to the air. Illstead of discllargillg the water tllrougll the cock J into thesupply-pipe, the said cock nla-y be so hollowed that it will discllargc directly upon the bed-plate of the frame A, or into any other receptacle. When the plllllp is to operate, the cock J is tllrlled so as to close the apertures s t u r, alld prevent tlle discharge of water through tlleln. The cock J is to be used simply when the water in the pulnp is to be prevented from freezing, and while the pump is not in operatioll.

L is the plunger, and M the plunger or pistoll rod. The body of the plunger is colnposed ot a metal plate, u, which rests against a sllolllder, a, of the piston-rod, alld of another lnetal plate, y, which, by a screw, z, is screwed against an elastic annular plate, a", which surrounds the piston-rod between the plates 1c alld y, as sllown in Fig. 11. The annular plate a* is made of rubber, and ot' lmlcll smaller external diameter than the plates 1v y. Around this annular plate a* are placed one or lllore leather rings, b", whose illner diameters correspond substantially with the outer diameter of the rubber ring a". The outer diameters of the leather rings b* are intended to tit tightly illto the cylinder B, but when the plunger begills to rllll too easy, the nut z is screwed farther toward the slloulder al, so as to compress-. c., flattenthe rubber ring a", alld thereby enlarge its diameter, alld expand the leather rings b". Vl'e find this collstructioll ot' the plunger to be far superior to any other heretofore proposed.

N is the operatillg-lever of the pump. Itis by a pivot-pill connected by a link, d", which is connected with the cross-head at the end of the plllllger-rod M by another pivot-pill, e", or, it' the crossllead is to be dispensed with, the link may hey joined by said pin ex directly to the plunger-rod M. The pivot-pill e", which joins the link dc to the plunger-rod M, is held in place by two projecting cheeks or wings, f that are formed on the lever N, said lever straddling the piston-rod in the usual manner.

Bythese cheeks or Wings f* We are enabled to hold the pivot e* inplace Without requiring ,additional means of fastening it, such as expensive screw-thread or transverse pins, or other device. The link-connection d", between the lever and plunger-rod, We deem an important improvement, as it enables us to dispense with considerable iction in operating the pump.
