UNITED STATES PATENT EETCE.
ALBERT M. PUTNAM, oE ANTEIM, NEW HAMPSHIRE."
IMPROVEMENT IN PUMPS.
To allzu/hom it may concern,.-
`Be it known that I, ALBERT M. PUTNAM, of Antrim, in the county of Hillsborough and State of New Hampshire, have invented an Improved Double-Acting Force-Pump, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a view of the pump; Fig. 2, a vertical section through the same; Fig. 3, a view of the under side of the cylinder; Fig. 4, a plan of the base with the cylinder removed.
The object of my present invention is to produce a double-acting vforce-pump which will be cheap and durable in its construction and all the valves of which will be readily accessible if they should require repairs; and my invention consists in the pump which I will now proceed to describe in such terms that others skilled in the art may 'u nderstand and use my invention.
In the said drawings the body of the pump A is a cylinder with flanges a at top and bottom. A cap, B, is secured on the top of the cylinder by screw-bolts passing' through the flange, and the cylinder rests on and is ysecured to a base," C, of sufficient depth to contain 'water-ways, which are cast in it. As all the valves which are used-four in numberare placed on the upper surface of this base C, they are all readily accessible by removing the base from the cylinder. 'lo the cap B is attached a standard, h, to which is pivoted the brake D, by which the `piston E is operated.
The outlet pipe or nozzle F is also attached to this cap. Tithin the cylinder A is another cylinder, G, in which the piston E moves. It is attached to the cylinder A by `division-plates or partitions c d e f, which thus form chambers H I .I K. The larger one, I-I, I term the air-chamber. The top of the cylinder G is i cut down opposite to each of the chambers I and J, thus forming ports g 7L, andthe partition fis cut off at its lower end t'o form a communication from the chamber H to the chamber K. This chamber K communicates at -top by a holethrough the cap with the nozzle F. The two cylinders with the partitions may all be cast in one piece. The base C contains a water-way, i, into which opens the in duction-pipe la, and which has two ports commanded by Iiap-valves l m. Another waterway, n, (shown dotted in Fig. 4,) has an open port, o, and one commanded by a valve, 1J, and the third water-way, q, has an open port, r, and one commanded by a valve, s. All these flap-valves open upward from the` upper side of the base. Vhen the cylinder A is in position on the base, the several ports in the base occupy the following positions relative to the chambers: The open port r and the one covered by the valve l open into the central cylinder, G, the port s into the chamber I-I, the port p into the chamber K, the port -0 into the chamber J, and the port m into the chamber I.
The pump being full of water, the followp ing is its operation: As the piston E is raised, as in Fig. 2, the valve Z is lifted, and water is drawn into the lower part ofv .the cylinder G from the induction-pipe 7s., The valves s and m being shut down, the water above the piston is forced th rough the port h, down theA chamber J, through open port o and water-way fa, lifting the valve p into the chamber K and out cf the nozzle F. I/Vhen the piston E descends at the next stroke, the valves l Vand p are closed, the' valve m is opened, and water is drawn from the pipe 7c through this valve up the chamber I and through port g at the top of this chamber into the cylinder G abovethe piston, while the water which was below the piston is forced through the open port fr, water-way q, and, lifting the valve 3, passes into the chamber H, thence under the lower end of the partition f, which, as before stated, is cut off shorter than the o1 hers, and up the passage K to the nozzle F.
The outlet or nozzle F is formed with an orifice at its outer end at u and another one 1 at Q: at the top of the straight part of the pipe,
to the inside of the pump, and it empties itself 0f Water through the induction-pipe k. This is sometimes necessary to prevent the pump from freezing' up in Cold Weather. At other times the tube is turned s0 as to @lese the Openings into the \\ate1.'-\VLys.
"hzit I Claim as my invention, and desire to secure by Letters Patent, is
The above-described pump, Consisting Of the pistou E, Cylinders A and G, chambers H I J K, with ports g and h, in combination with the base C, Containing' water-Ways 'L' n q, with open ports o' 0 and vulves l 711j s p, arranged und Operating' substantially :1s described.
