Letters Patent,No.'109,534, dated November 22, 1870.
IMPRovEM'ENT iN PUMPS.y
The Schedule referred to ln these Letters Patent and making parl: of the lsinne.
l'o all whom it may concern Be Iit known that I, JOHN H. MCGOWAN, of lGlncinnati, Hamilton county, State of Ohio, have invented a certain new and useful Improvement inBecipI-ocating Force-Pumps; and I hereby declarethe following to be.
a sufficiently full, clear, and'cxact'description thereof to enable one skilled in the art to which my invention appertains to make and useA it, reference being had to the accompanying drawing forming part of this specitication. y ,f
Nature and Objects of Invention My invention 'consists of a peculiar Construction of pump, by which the .air-chamber for the fsuction or lsuppl y current is located entirely withinthe air-chamtion-passages shall .be at all times surrounded by water,
and leakage 'of air thereby prevented.
Description of the Accompanying Drawing.
vFigure -1 isa vertical section of.a pump embodyingmy Invention.
Figure-2 is a horizontal cross-section of the same,
with the valve-chamber and valves removed.
Figure 3 is a verticabsectiou through the valvecli-ainber, at right angles to the section shown in g. 1.
General Description..
A is the barrel ofthe pump; B, the piston', G C', the suction-valve chambers; and D, the discharge-valve chambers.` E is the/suction or supply-pipe, and F, the/discharge-pipe. G is the air-chamber for the discharge water, which is formed to surround the pump-barrelA.
In the annular space between the air-chamber and.
struction necessary to prevent the abstraction of the. air by the water current, viz., a balloon or bottle-shape,
having a small neck or throat,` and it serves, as do others for the same purpose, to render the flow of the supply Water nearly uniform.
J J are the suction-valves, and
K K', the discharge-valves.
The supply water passesthrough valve J and pass- A age L to the bottom of the pump, and through valve J and passage M to the top of the pump.
lhe passage or side pipe M also carries oli1 the disl charge water from the upper end-fof the pump to the general discharge-chamber I), through vthe valve K'; and-the passage L, the discharge-water from the bottom of the pump to the chamber 1),'tl1rough the valve K. f
The chamber D is in constant communication with die aircliamber G, through diving-passage N and opening O at the bottom ofthe air-chamber. This air-vesseh'as in all other pumps, serves to render the discharge water Anearly uniform in its flow. It communicates withthe discharge-pipe F through the side openings l.
.It will be seen that the air-vessel H is wholly within the air-chamberG, and is atzall`-times submerged in water, so Ithf'tt,faltl1ough-` the joint at the bottoni'otf the air-vessel H maybe leaky, it will he impossible for the -joint to admit air to destroy the suction and in any way to seriously atiect'the action of the pump.
In 'orderthat cious as possible in the space afforded it, I make it of an lelliptical shape, as shown in fig. 2.
The passage to the space below both suction-valves and air-vessel H is not divided, and is always open, the partition It It merely extending down `to form a junction with the inclined lower valveaces.
In my patent Of-June 27,1854, No. 11,169, 'a suction air-vessel is shown, which is partially within' the discharge.air-vessel, being cast to it, butthis having( its lower joint open to the outside in common with the outer air-vessel, and the joint being also exposed to the side pipes and cylinder, is' liable to take in air from any direction, and requires a carefully-made joint to operate at all. f
The joint ofthe vessel H herein shown has no connection with outside of the pump, and is submitted exterior-ly to nothing but water pressure,.being entir'elyl submerged at and above the joint by the water ofthe discharge.
Claim.'
The air-vessel H, when located 'Wholly within the air-chamber G,- and 'detachably connected with the baseot the pump, as and for the purpose specified.
In testimony ot' which invention I hereunto set my hand.
