AARON GARYER,.OF LITTLE FALLS, NEW' YORK.
IMPROVEMENT IN FORCE-PUMPS.
Spociilcatihh forming'purt of Letters Patento. 43.180, dnlcd June 2l, 1864. l
To all whom it may concern:
Beit known that I, AARON CARVER, of Lit-l ile Falls, in the county ofHerkimer and State of New York, have invented a new and useful and Improved Sin gle-Chamber DoubleActin g y Anti-Frost Force-Pump 5 and I do hereby de- To enable others skilled in the art to make and use my improved pump, I will proceed to describe its construction and operation, referring to thedrawings, in which the sameletters indicate like parts in each of the figures. Figure 1 is an elevation of my improved pump. Fig. 2 is a sectional elevation of the pump cut perpendicularly through the center; Figs. 3 and 4, plans of the upper and lower diaphragms; Fig 4, a plan ofthe piston.
ment 4in doubleacting forcepnmps consists in the construction and arrangement described and claimed in the following specification.
il In .the accompanying d'rawings,A is the cylinder, made ot' cast metal, open thrcugh its whole length and of a uniform size from end t) end. The bottom plafe, B, is fitted to the lower end of the cylinder and-fastened bythe bolts C C. hemispherical, with an opening, I), 'in the center forthe water to enter below the piston,
which opening I) is closed by the ballyalve E. To prevent the ball E from being carried too far from'the opening by the water, I fasten the diaphragm F (shown in planin Figzfli) in the lower end of the cylinder. v
The diaphragm F is perforated to let the water pass freely through it, `and provided with guide-pins G G, to hold-the ball E right over the opening ID. The top plate, H, is fastcned to the cylinder by the bolts G C, which hold the bottom plate. The plate H has the pipe I extending up from it,t o which a metal or wooden pipe may be connected to conduct the water pumped wherever desired. There are four holes, J J, in the top plate, H, for the water to enter above the piston, which holes arc closed by the ball-valves K K, and to prevent the balls'K from descending too far, I
' fasten the perforated diaphragm L (Fig. 3 is a plan) in the cylinder,by screws or otherwise, in the position shown in Fig. 2; and there This plate is made V'concave or` aresome guide-pins, N N, inthe top plate, H, which hold the balls Krightunder the holes J.
The piston I is shown in plan, Fig. 5, and in section' in Fig. 2, and. is fitted to the inside'of the cylinder A, and consists of two horizontal plates@J and It, connected by the hoop S, with the valve T between them. Both ofthe plates Q and R are perforated, as shown in Fig. 2, and when the piston is drawn up the valve T closes the holes in the plate It, and when the f piston is forced down it closes the holes in' the plate Q, so that the ring-valve T does double service. The plate Q is perforated in the center, and has the hollow piston-rod U fastened in it, which conduct-s the water pumped from the cylinder up into the pipe I, when it passes out of the rod through vthe opening V. The
piston-rod may be 'connected to a crank, lever, -v orotherdevice to work it. The nature of my invention and improve-` There is a hole in the pipe I at W, and a hole' in the piston-rod right opposite to it, to let the water out of the pipes before it freezes. There is a recess, X,
on the inside ofthe pipe I,so that if the pistony rod is turned the water will run through the holein the rod and around in the recess tothe '.hoie W, so as not to vfreeze up inthe pipes up, the valve T closes the holes in the plate It, and the water is drawn in by the yalveE and'fills the cylinder below the piston. -WVhen thepiston is forced down, the yalveE closes, and the valve Tcloses the holes in the plate Q, so that the water below the piston is forced.
throughthe hole in the valve' T, up through the piston-rod. `When the piston was forced down, it drew thewater in by .the valves KK and 'filled the cylinder above the piston, so
that when the piston is raised the valves K close, and the ringVaIYeT closes the holes in the plate R, and the water above the piston passes throughy the plate the piston-rod.
I claimv l'. The cylinder A, provided with ports'and valves latboth ends,substantial ly as described, in combination with the peculiarly constructed piston P and hollow pistonroil.
