Description
5mm -latutl 1. N. FORRESTER AND JAMES H. LUDDINGTCN, or BRIDGEPCRT,
- CONNECTICUT.
Letters .Patent No. 85,577, (lated January 5, 1869.
To all whom it may concern Be it known that we, I. N. Fonnnsrnn and JAMES H. LUDDINGTON, of Bridgeport, in the county of Faireld, and State of Connecticut, have invented a new Iand improved Pump; and we do hereby declare that the following is a full, clear, and exact description thereof,
which will enable others skilled in the art to make and use the saine, refereime being had to the accompanying drawings, which represent a vciticalcentral section of our improved pump.
This'iuvention relates to a pump of that class in which the pumpylirdcr is made movable around a stationary piston; and
Its objectis to make the central discharge-tube stationary, so that the water-pipe can be attached toit at any desired place, and do away with the wooden supports in the well..
. The objet'of the invention is also to produce a convenient valve-arrangement, which will allow the apparatus to be worked with but little friction.
The invention consists in the use of a hollow piston,
.tted around the stationary central discharge-tube, in
such manner that tcOmmuniCates with the same, and arrangedwithin a cylinder that is suspended from a rod, and suitable lever-arrangcment, by means of which reciprocating motion can be imparted to it.
The piston and cylinders are provided with a series lof valves, by means of which the influx of water witliin the pump is regulated, so 'that a continuous stream will be produced. Y
A, in the drawing, represents a metal tube, with a l closed lower end, standing on'th bottom ofthe well.
This vtube forms the guide of the pump-'cylinder B,v
which is'ftted around it, and supports, also, the hollow piston C, with which it connnnnicates. The tube is perforated within the piston, as shown,
so that the water canreadily pass fronrthe piston into A,
the tube.
, The piston ts well against the side of the cylinder,
which is suspended from suitable levers, or other pumping-mechanism, by means of a rod, D.
In the upper head, al, of the cylinder, is fitted a valve,
b, and in the lower head, c, is arranged a valve, al.
The heads of the hollow pistou are also perforated to permit motion to a double-acting valve, e, which is arranged within the said piston, as shown.
W hen the cylinder is moved downward, the head a will be moved against the piston, and its valve, b, Will consequently be closed, while the valve e will close the aperture of the lower head, g, of the pistou, while that ofthe upper piston-head, f, will remain open.
The fluid contained in the upper compartment of the cylinder will thus, during the downward motion ofthe latter, be forced into the piston, and thence into the pipe A, as indicated in the drawing. .The 4lower compartment of the cylinder will, at the same time, be filled with fresh water, the valve l being opened, as shown.
Vhen the motion of the cylinder is reversed, that of thewater will also be, as then the valve l) is opened and (Z closed, while c will close against the upper piston-head, f. The water will then be forced into the piston from the lower compartment of the cylinder, while the; upper compartment of the saine will be refilled.
Having thus described our invention,
I We claim as new, and desire to secure by Letters Patentl rlhe pump, consisting of the movable cylinder B, which 'has the valves b and d, and of the stationary piston TC, secured to and communicating with the supporting-tube A, and, provided with the double-acting valve e, all made, combined, and operating substantially as herein shown and described.
