PUMP.

SPECIFICATION forming part of Letters Patent No 365,835, dated July 5, 1887.

To all whom it may concern.-

Be it known that I, SAMUEL W. MARTIN, a citizen of the United` States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in Io pumps.

My invention consists of a single uniform cylinder having two distinct plunger portions and a water-discharge between said portions, two plunger-rods arranged to travel at unequal speeds and distances and each having a plunger-one for eachpluuger portion of the cylinder-and suitable supports for suspending the cylinder below the platform. Y

My invention further consists of the uni- 'form cylinder, plunger-rods, plungers, and,

supports for the cylinder, when combined with a head which rests upon the platform and holds the supports, and which is constructed to allow the rods to pass up through it and to permit the plunger-rods and their plungcrs to -be drawn up from the cylinder and lifted out through the head without in anywise disturb4` ing the tixed part-s of the pump.

My invention still further consists of the v 3o suitably-supported cylinder and the two plumgers and their rods arranged so that the up per plunger can be held at rest, to close the upward escape of the water, and the lower plunger be continued in operation, whereby '3 5 the force-pump is converted into a lift or single-acting pump capable of being actuated either by hand or by power-as by a windengine-this latter being principallyin view, as the loss of time between the lifting action 4o of the plunger allows time for the Wind-engine to regain momcntum-a very important practical consideration.

My invention yet further relates to certain featuresof construction in respect to the snpporting-head and the actuatinghandle and its connection with the plunger-rods and one of said rods and the checlevalve.

In the accompanying drawings, forming a part of this specification, and on which like 5o reference-letters indicate corresponding parts,

"xnunication with the cylinder at points be- Application filed January 10, 1887. Serial No. 223,916. (No model.)

Figure 1 represents a vertical sectional View of myimprovedpump entire; Fig. 2, a sec tional view of the cylinder, showing the lower plunger and the check-valve therein; Fig. 3, a detail plan view of the top ofthe head; Fig. 4, a cross-sectional and plan view of the head, showing the flange around the lowerend; Fig. 5, a sectional View of the upper end of the head and of the plunger-rods and pluugers, showing more clearly the relative sizes of the plungers and the opening in the head; and Fig. 6, a plan view of a fragment of the actuating-handle.

The letter A refers to a wellplatform, of any approved type, upon which is mounted the holding or supporting head B. This head is preferably constructed in two vertical parts and substantially like the head shown and described in Letters Patent granted to me De cember 28, 1886, No. 35i-,920, for improvements in pumps. It differs, however, from that head in two particulars-namely, in be ing laterally enlarged at O C, to allow the plungers and the checlevalve to be lifted out and put down through it, and in having'a detach able cap, D, fitted to an opening in the top. This cap on being removed also allows the vplungers and check-valves to be withdrawn lor inserted into place, and while on the head serves to substantially close its upper end, and yet, by reason of the slot E therein, permits the plunger-rods to work freely. The parts of the head are held together by bolts, as seen in dotted linesin Figs. 3 and 4, and iu seats or bearings F are placed and held the supports G. These supports are, by preference, of tubular form, and in this instance one of them forms, also, an air-chamber, and the other a dischargepipe, both being in comtween the plungers.

The letter H designates the cylinder, which is uniform,or to all intents and purposes substantially so, in diameter in both of its plunger-working portions, of which there are two-- one for each plunger. At I the cylinder has short branches, and these branches receive the supports. In the lower end of the cylinder a IOC) the periphery to cause the valve to seat itself snugly into the cylinder, in which case it needs no other fastening. The valve, however, whatever be'its construction otherwise, is provided `with a part with which the longer plunger-rod is readily engaged, as larms L, having interiorlyscrew-threaded holes at their juncture, into which that rod is entered by disconnecting it 'from the handle, letting it far enough down and then revolving it. By this means the valve is lifted out of the cylinder, should repairs or other cause require.

The letters M and N respectively refer to the longer and shorter .plunger-rods, which respectively carry the lift and force plungers O and I). These plungers work in the respective plunger portions of the cylinder H, and are of any approved construction. The plunger I? has a stuffing-box, Q,which prevents the water from rising above it and around the plunger-rod M. It should be noted that the rod N is tubular and that the other rod passes through it. Both are connected to the actuating-handle R, pivoted in standards S of the head, one standard only being shownM directly and N through an extension, T. The point of connection between the plunger-rod N, through its extension, and the handle is preferably about half the distance between the connection of the rod M and the fulcrum-point of the handle. Therefore the movement of the plunger P is approximately halfas fast and half as long as the movement of the plunger O. This overtaking f action of the lower plunger causes it to undertake to compress the hydrostatic column between the two plungers, and this being a physv ie'al impossibility, being resisted by the natural solidit-y of water, results in forcing that column outof the cylinder and upward through the discharge-pipe, as G. Themen the downstroke,the upper plunger acts upon the water which followed it up into upper-plunger portions of the cylinder, and forces that column out, as it is met and resisted by the column which in the meantime was formed under the lower plunger. Thus the stream is continuous. Vhile it is a fact that double-acting,` force-pumps are superior as hand-pumps to single-acting lift-pumps, there are yet a class of users who prefer the latter kind of pump lwhen it is to be operated by a wind-engine.

Therefore, and to meet the demands of this class,I disconnect the longer rod from the handle and attach it to the pitman of a wind-engine, allowing the upper plunger to remain still and close the upper end of the cylinder, in which instance the pump is converted into a single-acting lift-pump.

If desired, the handle can be bolted to the standard, as at U V, by the bolt which connects it with the longer rod. This insuresthe upper plunger against accidental movement. The pressure `of the water upon the under side of the upper plunger and the weight of the handle will hold the plunger, however.

- It will be understood that the cap D is first to the lower plunger be correspondingly changed, and I would therefore have it understood that such a change is fairly within thescopeof-this invention. Thelower-plunger portion of the cylinder and the lower plunger may of course be extended indefinitely down,

as in the case of deep wells, without departing from the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a pump, the combination with a uniform cylinder divided into two plunger-working portions and supports connected to it, one of which forms a discharge-pipe and communicates with the cylinder between the said portions, of ashorter tubular plunger-rod and a plunger working in the upper of said portions, and a longer plunger-rod within the other rod, and having a plunger for the lower of those portions, and a pivoted handle, tothe shorter arm of which both of said vrods are connected, one adj ustably, at different distances from the pivotal point.

2. In a pump, the combination, with anni- 'form cylinder divided into two plunger-working portions and an intermediate portion into which the plungers do not travel, supports connected to the intermediate portion, one an air-chamber and the other a discharge-pipe, and a head upon the platform which holds the said supports, of a tubular pl linger-rod having a plunger for one of said plunger portions, and a plunger-rod within the tubular one, and having aplunger for the other of said plunger portions, and a pivoted handle, to the shorter arm of which'the plungers are detachably connected, whereby both plungers may be operated at different speeds and-distances, or one left to rest and the other operated. y Y 3. In a pump, the combination, with a cylinder divided into two plunger-working portions and an intermediate portion in which the plungers do not work, supports connected to the cylinder, one of which forms a discharge-pipe and communicates with the said intermediate portion, and a suitable head to secure the supports at the platform, of two plunger-rods, each having a plunger, and a pivoted handle to which said rods are connected, one detachably, whereby one rod may be left to rest while the other is actuated to form a single-acting pump.

4. In a pump, the combination, with ahead having seats for cylinder-supports and an enroo IIO

larged interior passage through which to withdraw the working mechanism, of the tubularcylinder supports fitted into said seats and held thereby and forming a discharge-pipe and an air-chamber, a uniform cylinder divided into upper and lowerplunger portions and open at the top, and plungerrods, one within the other, and each having a plunger, one lower than the other, and both rods extended up into and above the head and with their plungers adapted to be withdrawn from the cylinder and through the said passage in the head.

5. In a pump, the combination, with a uniform cylinder divided into upper and lower plunger portions and open at the top, and supports connected with the cylinder and extending upward to and connected with a head, of

the head having seats which receive and hold said supports, and an interior enlarged passage through which to withdraw'the Working mechanism, and plunger-rods, and their plungers extending up to near the upper end of the head and through said passage in the head.

6. In a pump, the combination, with a uniform cylinder open at its upper end, of a' the opening in the head, when the cap is rel moved, of the lower Working mechanism.

In testimony whereof I affix my signature in presence of two witnesses.
