IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 192,264, dated June 19, 1877; application filed May 17, 1877.
To all whom it may concern:
Be it known that I, EVAN JONES, of Ottumwa, in the county of Wapello and State of Iowa, have invented certain new and useful Improvements in Pumps; and do hereby declare that'the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention consists-in the construction and arrangement of a pump, as will be hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, which represents a longitudinal section of my improved pump,
A represents a straight tube of any suitable dimensions, enlarged at the upper end to receive apacking-box, B, through which works a hollow plunger, 0.
a is the packing, and b the washer, resting on a shoulder, d, in the tube A, and against which the box B screws tightly, to pack the hollow plunger 0.
The plunger 0 is of smaller diameter than the inside of the tube A, and is closed at its upper end. The lower end of said plunger is provided with exterior screw-threads, on which is screwed a cup, H, forming the bottom of the plunger, and from which projects a rod, h, having a piston, D, secured to its lower extremity. This piston fits tightly in the tube A, and has openings '5 through it, which are covered by a valve, E, sliding on the rod h. In the bottom H of the plunger (3 are also openings 00, as shown.
If necessary, the hollow plunger 0 can be easily detached from the cup and piston, and removed without taking the piston from the tube.
On the lower end of the tube A is fastened a valve-seat, G, with valve G to connect with the supply in the usual manner.
By the joint action of the hollow plunger 0, which forms an air-chamber, and the valvepiston D E, of difl'erent areas, connected together and working simultaneously in a straight tube, a continuous stream of water is made to flow from the pump in a steady and regular manner. I is the outlet.
The pump is cheap, compact, durable, and effective in operation.
Having thus fully described my invention,-
