UNITED STATES PATENT OFFICE.
LEVI P. DODGE, Ol? NEIYBURG, NEIV YORK.
IMPROVEMENT IN PUMPS.
Specification forming part ol Letters Patent No. 35,l22, dated May 13,1862.
To @ZZ whom, may concern,.-
Be it known that I, LEVI P. DODGE, of. Newburg, in the county ot- Orange and State of New York, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the following is a full and exact description ot the same, reference being had to the accompanying drawings, in which- Figure l is a vertical section of my improved pump attached to a plank in the manner I usually employ `it in wells, and Fig. 2 is a perspective view ot" one of the brackets by which the rod is steadied when the pump is placed in a very deep well.
To enable others skilled in the art to make and use my improved pump, I will proceed to describe its construction and operation by the aid ot the drawings and of the letters ot' reference marked thereon.
A is the barrel of the pump, provided with a piston, Il, operated by a rod, l), passing` through a stuffing-box, d, in the ordinary manm-nf. Passages t" and l) admit the water to each end of the barrel, and each passage is provided with a ball-valve7 c d, the valvechambers being so arranged that they are both accessible when the barrel A is removed from the casting E, containing the seats for the said valves, the advantages of which will be obvious. Discharge-passages l? G extend t'rom each end of the barrel to the air-cham# ber Il', each terminating in a valve-seat, f g, in the same plane'with the top ot' the barrel, as represented, rihe lower portion of the airchamber lfl is divided by a partition, I, into two valve-chambers, l L, for the reception of the valves M N, a cross-bar, O, cast therewith, serving both to steady the partition and as a check upon the valves. The partition I, the bar O, and the central pipe, P, are all cast in one piece with the air-chamber, by which means I secure a tight air-vessel, and the lower end ot' P maybe flared, as represented, to receive the water with little friction or change of motion, and the bar O steadies the end oi P, so that it does not spring out ot place, which latter fault frequently occurs with a pipe soldered in in the ordinary manner. It will be seen that both valves M and N maybe removed and replaced by simply opening, technically termed breakingf the joint between the pump and air-chamber, while the valve-seats, being directly upon the surface, are very readily litted or repaired.
The piston is made in two parts, I3 and B', one of these parts being fitted nicely to the interior diameter of the barrel A, and the other, IE, being turned enough smaller to al-v low of packing R being placed upon it.
By my arrangement of the valves and val ve-seats and passages and of the valvechambers and airvessel I secure several important advantages in cheapening the manufacture and diminishing the trouble of repairing of my pump. By reason of the arrangement otl the passages F G in the casting with the cylinder and ot' the valve-chambers for the valves M N in the base of the air-ves sel compressed together in the manner shown I avoid making' more than one joint, and am able to make that a very small and easily-adj usted one. By reason of making the base oi' the air-chamber in the same plane with the end oi. the cylinder, I am able to plane and properly tinish both at a single operation; and by reason of making the valve-seats fg directly upon the surface of the casting, as shown, they are very easily accessible for any repairs by the removal of the air-vessel.
The diagram on the sheet of drawings shows the pistonon a larger scale than the gures and in the position which I prefer.
I'Iaving now fully described my invention, what I claim as new, and as'of my improvement in pumps, is as follows:
l. The arrangement of the valves M N in the valve-chambers K L in the base of the airvessel Il, and arranging the seats f g near the joint between the parts, so that there is but a single joint of small area connecting the passages F G with the airchamber, all as herein set forth, and for the purpose specified.
2. In combination with the foregoing, arrangin the joint connecting the air-chamber and the cylinder-casting in the same plane, so that both maybe finished at one operation, as herein set forth.
LEVI P. DODGE.
