PUMP.

- $PB CI1 ICA'IION forming part of Letters Patent No. 325,623, dated September Application died March 5, 1885. (No model.)

To all whom it may concern:

Be it known that I,*Jsnrrr M. NORMANID, 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.

My invention relates to that class of pumps in which two cylinders of different capacities are arranged one above the other in such a manner that only half of the water drawn up by the lower and larger cylinder is discharged on the upstroke, the other half being received by the upper and smaller cylinder and discharged by the downward stroke, whereby a constant stream is maintained at the dischargepipe.

The object of my invention is to simplify and eheapen the construction of pumps of this water-passage from the lower end of the up-' per cylinder opening into the discharge-pipe. My invention further consists in the arrangement of the eecentrically-located pump.

lug-cylinders with a water-delivery stock provided with a drop-pipe adapted to form an air-chamber in said stock.

My invention further consists in various other constructions and combinations of parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a vertical sectional elevation of a pump embodying my invention. Fig. 2 is a top view of the cylinders, showing the upper pistonrod in section. Fig. 3 is a perspective view of the top or head of the pump. Fig. 4 is a sectional view showing the arrangement of the pumping-cylinders for deep-well pumps. Fig. 5 is a plan view of the lower pump-valve.

,rocating pump-rod 6.

Figs. 6 and 7 are a vertical sectional elevation and plan view, respectively, showing a modified form of the cylinders; and Fig. 8 is a detailed view of one of the pistons, shown partly 5 5 in section.

In the said drawings, A represents the up per and B the lower cylinder, and A and B the respective pistons therefor. The upper cylinder, A, I preferably make of a straight round tube of brass or other suitable material, screw-threaded at the top and adapted to be screwed into an opening, a, inthe upper end of a casing, C, so as to depend into said casing. This casing G is cylindrical in shape at the bottom, and is adapted to be secured to the top of the lower cylinder, 13. The casing 0 may be secured directly to the top of the lower cylinder, B, as shown in Fig. 1, or by providing caps D D and pipe D, as shown in Fig. 4. The lower cylinder may be located at any desired distance below the said casing. The casing C is supported by the pump-stock E, which is connected to a neck or projection,

b, on the top of the casing O. This neck I) is 7 5 offset over the opening a, into which the upper cylinder is secured, and is connected by a c, to the inside of the casing O. The A, is provided with a stem, d,

said stem being provided with a longitudinal slot, d, and adapted at its upper end to be connected to the recip- This piston-stem d is adapted to bear against the neck b, which is extended over to the center of the upper cylinder, A, the stem being preferably cast on an arc corresponding to the curve of the neck I). A bolt, f, provided with an enlarged head and adapted to pass through the longitudinal slot (1, is screwed into the side of the neck Z1, 0 and serves to hold the piston-stem d against lateral movement thereon, at the same time permitting longitudinal movement of said stem. The top of the pump-stock E is surmounted 5 by a cap or head, E, provided on one side with a laterally-projecting lug, 9, adapted to form a bearing for the oscillating handle F,

to which it is attached by a bolt or pin, 9. The handle F is bifurcated at the upper end ro and projects forward on each side of the head E, and is connected by means of a bolt or upper piston,

pin, h, to a T-shaped connectingpiece, h, which is secured on the end of the reciprocating pump-rod e. The pump-head E is reduced at its upper end and tapped out to re ceive the end of a drop-pipe, H, which is screwed therein and extends downward into the pumpstock, thereby forming a dischargeopening for the water, and at the same time creating an air-chamber in the upper part of the pump-stock E. The pipe H extends only part way through the reduced portion of the pump-head E, said head being long enough to receive the end of a curved pipe, H, which is screwed therein and forms the pump-spout or dischargepipe proper. This spout H,extending as it does from the center of the top of the head, is adapted to be turned to any relative position with the handle F--a point of considerable advantage in locating pumps in crowded places. By providing a lock-nut, 93, on said pipe means are furnished for securing the spout in any desired position and at the same time making a tightjoint.

The lower end of the lower cylinder, B, is closed by a cap, I, adapted to receive at its lower end the inlet-pipe J, which is secured therein. Immediately above the inlet-pipe J a recess, 7c, is formed in the cap, adapted to receive aring, Z, of hard or vulcanized rubber, This valve m is made from a leather gasket,which 1 extends over the top of the cap and between a the said cap and the end of the cylinder, the 1 adapted to form a seat for the valve m.

said gasket being cut out, as shown in Fig. 5, to form the valve, and a weight, at, placed on top thereof, as shown. The leather valve, as thus described, in combination with the rubber valve-seat, makes a very tight-closingvalve, not liable to rust or stick. This construction, however, will be made the subject of another application, and is not therefore claimed in this.

The connection between the upper and lower piston I preferably make by means of a straight piston-rod, n, which is screw-threaded at its upper end and tapped into the bottom of the upper piston eccentric thereto.

The pump-pistons are provided, in the usual way, with a packing-ring, p, of leather, which is compressed into the shape of a ring with an internal annular flange. In order that the packing may be readily applied or removed, as desired, I provide on the lower side of the piston a boss or neck, 1), equal in diameter to the internal diameter of the said annular flange. This boss 1) is screw-threaded and provided with a nut, 12", adapted to screw thereon and bind against the annular flange of the packing-ring p, the external diameter of the nut being equal to the internal diameter of the packing-ring.

In the bottom of the neck 12, where it extends over the upper cylinder, A, I provide an inwardly-opening valve, 0, provided with an outwardlyprojeeting stem, adapted,when the piston A is raised to its limit by the downward stroke of the handle F, to be engaged by said piston, and thus open the valve, thereby automatically draining the pump-stock and preventing the freezing of the same.

If desired, a variable stop may be provid; ed for the handle F, so that when desirable the handle can be stopped on its downward stroke at a point not sufliciently advanced to open the valve 0.

The action of the pump is obvious. The lower piston, B, is provided with an ordinary drop-valve, which permits the water to rise through said piston on the downstroke, and as the piston is drawn up the water in the lower-cylinder is partly discharged through the stock E and discharge-pipe H, and partly drawn into the upper cylinder, A, and is discharged on the downstroke of a said piston. As the water is forced up into the pumpstock it meets the column of air which surrounds the drop-pipe H in the top of said pump-stock,and is thus discharged in asteady and constant stream at the spout H.

By the construction above described asimple and very compact construction is secured, the whole being confined in diameter to the outer limits of the casing G. The top of the upper cylinder is left open, thus dispensing with the use of stuffing-boxes. A very large pump-stock is secured, permitting the airchamber to be formed immediately therein.

In Figs. 6 and 7 I have shown a modification in which'both cylinders are cast in a single piece and eccentric to each other.

Other modifications will suggest themselves to an ordinary mechanic.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the pump-stock, of two pumping-cylinders eccentric to each other, and a waterpassage from the bottom of the upper cylinder to the pump-stock,whereby the water is discharged through said pumpstock without closing the top of the upper cylinder or incasing the pump rod, substantially as set forth.

2. The combination, with the eccentric pumping-cylinders, of the outer casing, forming a passage .from the bottom of the upper.

cylinder, and provided with a neck offset over said upper cylinder, into which the pumpstock is secured, substantially as set forth.

3. The combination, with the pumping-cylinders, of an outer casing adapted to be connected at its lower end to the lower cylinder, and provided at the top with two openings on opposite sides thereof, one of said openings being adapted to receive the end of the upper cylinder,which depends into said casing, and the other adapted to receive the end of the pump-stock connected thereto, whereby the cylinders are placed eccentric to each other, and a water-passage formed from the bottom of the upper cylinder to the pump-stock, substantially as specified.
