IMPROVEMENT .IN PUMPS,

1'0 all whom it may concern .-1

Be it known that I, ISAAC N. FoRnEsTER, of Bridgeport, in thecounty of Fairfield, and State of Connecticut, have invented certain new and useful Improvementsin Pumps, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, which make part of this specification, and in whichv Figure l represents a vertical central section ot' my improved pump;

Figure 2, a plan or top view of its cylinder; and

Figure 3, a view of the bottom ofthe same, as seen from below.

My invention relates to that class of' pumps in which a moving cylinder or barrel is vemployed in connection with a stationary piston and tubularrod, and consists in an improved construction and arrangement of the receiving and delivery-valves by'which the tubular piston-rod is made to serve .for aediseharge-pipe as Well as a guide to the barrel in its movements, as hereinafter more fully set forth.

In the accompanying drawings, which show a convenient arrangement ot' parts for carrying out the ob jects of my invention- A represent-s the cylinder or barrel of the pump, which is reciprocated upon the central tubular, pistonrod and discharge-pipe B.

`The pipe B, which is closed at bottom, is fixed Ato a`baseep1ate, at y the bottom of the well, and supported by a collar, b', at its top.

C represents a pistou-valve, which fits truly within the barrel A, and surrounds the tubular rod B between the two collars B' B secured thereon by set-screws or keys.

The rod B is perforated with a seriesv of holes, bb, and a circularopeniug is formed at the centre of the valve C, to prevent the same from beingin contactwith the rod,and allow access of water to the holes b.

The collars B are set suiciently far apart to allow the valve C toerise and fall a proper distance to admit lthe water which passes through the receiving-valves to the rod B, .which serves as a discharge-pipe for the same.

The lower end of the barrel is closed by a bottom I head, A2, in which are placed the lower receivingvalves a a. These are wing-valves ot' the ordinary construct-ion.

same will enter the lower receiving-valves a a and ll When the barrel isrmoved upward, the valve O will rise and admit this water through the holes b b'to the tubular rod B, and the upper receiving-valveI A1 will fall and allow water to ill the space above the valve C.

The water will' be in turn discharged through the holes b and rod B, by the falling ofthe .valve C and rising of valve A3 on the-next downward. stroke, and

the pump. y

What I claim as my invention,and desire to secure by Letters Patent, is-. e

rIhe combination of the moving barrel A, sfationary perforated tubular rod B, collare 13.1, piston-valve C, and receiving-valves a a, A, the whole arranged and `operating substautiallyas and for the purpose set lforth.

In testimony whereof, I bave hereunto subscribed my name,
