IMPROVEMENT IN PlTCHER-PUMPS.
Specification forming part of Letters Patent N 0. 180,190, dated July 2' 1576; application filed May 8, 1876.
with the pump-handle, that the piston-rod mayhave a proper movement- The object is, by simple means, toprovide means for preventing water from being thrownup and out of the pump by the action of the piston. I
In the drawings, Figure 1 is a vertical section of a pitcher-pump, taken through the center ol' the spout.- Fig. 2 is an enlarged section, taken transversely to the spout of the pump and parallel to the pump-handle. Fig. 3 is a plan or top View of the, head-plate removed from the pump, corresponding in size to Fig. 1.
A represents the revolving cap of a pitcherpump of ordinary construction, and B represents the spout-section ;D, the spout; E, the
piston-rod; H, the set-screw lbrlustening the cap to section B, and I the support for the pump-handle.
Between the section B and the revolving.
cap A is formed an annular groove, suitable to support the edge of an annular head-plate, O, which covers the orifice in the top of the pump, except so much as the areaof the slot t'rom'a; to :0, Figs. 2 and 3, for the piston-rod E to work in. In order that the slot may always run parallel with the handle of the pump, a slot Z, Fig. 3, is made 'in the headplate, and anib or projection, Gr, on the under side of the revolving cap A, engages it and prevents the head-plate from turning.
I do not claim, broadly, the closing of the I ends of pitcher or other pumps; but
What Ifclaim is I I The head-plate O, placed between the revolving cap A and the'spout-section B, substantially as and for the purpose set forth.
