" IMPROVEMENT nv Pmv i' l i The Schedule referred 'to in these Letters Patent and making part of the same.
` i provementin' Pumps; `aiid `I `do declare thatV the `following is a trueand accurate description thereof',
referencebeing had to the accompanying drawing and' 'tothe letters of reference marked thereon, and being a part of this specification, in which- Figure-1 is an elcvatiom-partiallyn section, of my Figuic' `2 is aplan, partially in secticn,of the pump,- .piston. A Figure 3 is a horizontal section of the lining of. the barrel, taken on theline :c x, in tig. 1 and Figure 4 is a planet', the foot-valve,- also partially in section. Y Similar letters of reference indicate corresponding parts in each gure.A
The nature of this invention relates to an improved construction of wooden pumps, and consists iu the peculiarconstruction of andarrangement within the barrel of a sheet-inetallining or bushing, and in the peculiar construction Iof the piston and thevalves.V v
\ Arepresents awooden pump-head or stock, whih` Bisarliningof sheet metal, having a `ilange, a,
turned outward ou its upper and lower edges, and exi tending nearly aroundit; i
h `a 'lip`, foi-med at `the commencement of .each said lips pointing toward each other. The
wheige 4it is held `in place by the flanges entering the walls of thebarrel,f ei ther byexpanding the lining, and
"y and, forcingtheminto it, or` by'crozing ina pair of grooves fortheir reception, the outward spring of the metalteudingto keep it in contact with the barrel, following it when it.expands, and giving way to itin its contraction, the lips being employed to simply hold the ilapstoge'ther. l Y l O is a piston, attached tothe reciprocating pistonf rod O', operated in the ordinary manner.` .f
cli's a' cup-leather or packing, secured around kthe top of the wooden piston, which is ehamfe'red at its edge, to form anj annular.water-chamber between it andthe cup-leather, reaching nearly1down `to thebase `of thellatter, wedgingthe leather outward Yin the npward strike ofthe piston.
The lower half ofthe `valve is diminished in diallieter,as shown, and, from this part, aj row of openings,
In the ordinary methodof constructing such pistous the' openings for the 'passage Vof the water are bored directly throughthem, weakening them to such i an extent that they readily split; in the present form l the liability to split is avoided by carrying the lower solid part of the piston-well below -the entrance. of theV openings, thus insuring great strength therein. v f
. D is a disk, 'of stiii leather, forming a valve, or sel ries ci' valves, secured by a shoulder in the rod to the center off thepiston. It is radially and concentrically glooved, as shown 'at c, g. 2, the parts between thc grooves forming valves, which1 iu the downward stroke, are lenabled to rise, by reason of the flexibility of the grooved parts of the disk.`
E is a plug, perforated with suitable openings, j, for the admission of water.'v
D is a disk, forming the foot-valve, constructedas above described, and centrally secured to the plug vby an eye-bolt, g, by means of which th'e plug may be withdrawn from the pump-barrel, when desired.
.The'plug E `d iiieis in constructionfi'om those in ordinary use in this, that its top is coucaved or cupshaped to about the shape that vthe valves would,
Y l. The ilexible sheet-metal lining O, provided with ilanges d and lips b, constructed, arranged, and oper-A atingsubstantially as and for the purpose Vset forth.
2. The piston O, provided with the curved openings d, and with the cup-leather c and valve D, which Y -is provided with the grooves e, when each of said parts is constructed as described, shown, and setfortli, `and arranged to operate as and for the purposes above 3. In combination with the piston C,`providcd as .above described with the curved openings d, the cup- Vleatherc and valve D, with its grooves e, the plug E, with concave upper face openings f, cup-leather D', with its grooves c', all constructed and arranged to operate asand for the purposes set forth.
4; rlhe combination and arrangement of the pulnpbarrel A, flexible lining B, piston C, plug E, and
valves I) D', when constructed, arranged, and operating-substantiall y as described, and for Ythe purpose specified.
