To all whom it may concern.'
Beit known that I,HARRY JONES, a citizen;
mond, in the county of Wayne and State ofi Indiana, have invented certain inew and-useful Improvementsin Pumps; and I do hereby declare that the following is afull, clear, and exact description ofthe invepntion, which will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in whichl Figure 1 is a longitudinal sectional View, on a vertical plane, of apump embodying my improvement. Fig. 2 is a transverse sectional view ofthe same, on the horizontal plane indicated by the broken line marked efx'; and
l Fig. 3 is a perspective detail viewof my improved plunger, removed from the pump barrel. v
Like letters of reference designate lcorresponding parts in all the figures. l
This invention relates to pump pistons or plungers adapted, alike, to lifting pumps and force pumps, both double and single acting, the accompanying d rawin gs illustrating my invention as applied `to a single` acting lifting-pump; and myimprovenent has for its object to construct a self-packing or water packing plunger in such a manner that I obtain, on each up-stroke ot the plunger, a continuous annular sheet or body of water (or other tluid lnedium in which the pump works) which, by passing up from and through an annular opening in the body of the plunger against the adjacent side of the inclosing pump barrel, will provide a perfect waterpacking; substantially as will be hereinafter more fully described and claimed. Y
On the accompanying drawings, the letter A denotes the pump-barrel, which has the usual downward extension or suction pipe A', reaching down to the bottom ofthe wellor cistern in which the pump is placed, and is provided at the point ot connection between the barrel A and pipe A', with a valve seat b and valve u, which may be of any approved construction and forms no part of my present improvement.
The sucker-rod, or piston-rod, is shown at B,
into the bottom of the uppersection Cof my his upper part improved two-part-plunger'. or section C is in the Ynature and shape ot a cylindrical bucket, open at the top d, and provided in its bottom withradial arms c c, crossing one another at right angles (see Fig. 2), so as to form a central bearing at the point where theY arms cross one another, which has a central screw-threadedy aperture B for the insertion and attachment ot` piston-'rod B; thus forming four openings between the arms and the walls of the plunger. Y The lower part of this, in alignment with the arms'c c, is beveled on the outside',`as show ii at c', for the purpose hereinafter set forth.' The lower part or section of the'plunge'r consists also of a cylindrical bucketE, ofthe same diameter ofthe upper bucket C; but reduced or recessed at its bottom so as toform a circular recess e. On the inside, this lower bucket E is of the peculiar construction shown more `clearly in4 Fig. l; that is to say, its cylindrical'wall is provided on the'inside with four radial curved armsf, which converge in anupward direction and arerconnected at their lconverging upper ends toA the under side ofthe center of the spider or open bottom formed in the lower part ofthe upper bucket yC by its arms c c, so that the buckets C and E will be connected to each other, and to the piston-rod B, by means of the curved armsff appertaining to the lowerbucket, and straight radial arms c c forming the open bottom of the upper bucket. Below these inside arms ff, the lower part ot' bucket E ismade with gradually thickened walls forming the concave valve-cage F, within which plays the spherical valve or ball-valve G. Below this valve in the concavebottom which forms the lower contracted part ot the cage, is a circular interiorly threaded aperture h, into which is screwed the eXteriorly-threaded collar H of an annulus H, the circular rimof which projects beyond the circular recess orgroove e in the underside of the bucket, so asto'close this recess on the under side and thus form an annular groove or channel encircling the lower 4end of the bottom section E. Thus it willbe observed that the play ofthe ball-valve G is limitedor confined, within its cage F, between the concave apertured bottom of the same, on the under side, and the converging ICO deflected arms ffon the upper side, so that when the valve is in the down position on its seat, as shown on the drawings, the aperture or inlet, h to the valve-cage will be closed. This play of the ball-valve G within its cage may be regulated in a measure, by adjusting (i. e., screwing up or down) the annulus H with its collar H; the beveled upper end or rim of this collar forming the valve seat proper when screwed up above the rim of the interiorly threaded inner aperture 7i; as clearly shown in Fig. l of the drawings.
From the foregoing description, taken in connection with the drawings, the operation of my improved pump will readily be understood. The plunger should be of such diam-V eter, in both its upperand lower sections C and E, that it will work easily in the pump barrel without friction, or with a minimum of friction; and, by the construction and arrangement ot' the radialarms c andfit will be observedthat the annularapertureD,formed between the slanting or beveled under side c of the top section O,and the upper circular rim of the bottom section E, is clear or unobstructed all around the plunger, while the circular bottom chamber e is also leftclear, continuous and without packing. Now, on the up stroke of the plunger in its barrel A, water enters the pump barrel through the suction-pipe A and its valve and valve-seat a, b, and on the return or down-stroke, the water (or other liquid) with which the barrel is filled enters the plunger through its bottom valve. On the next up-stroke, the pressure of the water above the plunger causes a film of water to be forced from the top, above the rim of bucket C, down into the narrow cylindrical space between the plunger and pump barrel, as indicated by the darts marked g g and by the continued motion of the plunger in the same (upward) direction, the resistance or pressure of the column of water above and within the bucket C will cause an outflow of water under pressure through the annular orifice D, which, due to the bevel or incline c', will be thrown in an upward oblique direction against the inner adjacent sides of the pump barrel, as indicated by the darts marked a. At this point the two currents of water meet, forming a compact compressed water cushion or packing between the plunger and the pump barrel at a point, or rather von a circular line, intermediate between the top of the upper bucket C and the top 0f the lower bucket E, which will extend both in an upward and downward direction, filling the annular dead-water packing space D formed by the beveled lower end of the top plunger C and the top of lower plunger E. This pressure of water which Hows upward and V outward through the space' D between the two plungers, will be equally distributed at every point therein, thus centering the plungers or holding them in a vertical position within the pump barrel.
Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is as follows:
l. The piston for pumps comprising two hollow cylindrical portions `separated by a continuous annular peripheral port and each supported from a point in the axis by an open framework, constructed to allow free passage of water, whereby water is permitted to Iiow freely from the interior to the exterior of the piston in an annular sheet, as and for the purpose described.
2. The piston for pumps comprising two hollow cylindrical portions connected t0- gether internally by radial arms from a portion ou the axial line of the two cylindrical portions; substantially as described.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
HARRY JONES.
