Application filed February 1, 1915. Serial No. 5,462.
b aZZ whom it may concern Be it known that I, JoI-IN THOMPSON STREET Brown, Jr, a citizen of the United States, residing in Prospechcounty of Jefferson, and State of Kentucky, have invented a certain new and useful Improvement in Pumps, of which the following is a specification.
An object is to produce a double acting pump of the class described. Double acting pumps of this character have been produced before, but the structural arrangements have been such that the efiective area was reduced so'that the output was increased but little over that of a single acting pump having a working chamber of the same diameter, consequently these pumps have not'come into general use. 7
Another object of this invention is to provide a pump of the class described, having a straight line working chamber, the effective area of which is not reduced by. the structural arrangement and which will consequently have an output of substantially double thequantity of a single acting pump of the same diameter and stroke.
A further object is the provision of a- View, the invention has particular relation to certain new andnovel features of construct-ion illustrated in the accompanying drawing which forms a part of this specification wherein is set forth an embodiment of the invention, but it is to be understood that such changes and modifications maybe resortedto as come within the scope of the appended claims. I
Referring to the drawing wherein similar reference characters designate like parts in the several views; Figure 1, is a central vertical section, with portions broken away and parts in elevation, showing the plunger at the commencement of its upward stroke; Fig. 2, a perspective, of the upper valve case Fig. 3, an elevation of a modification of the upper valve, cage showing one depending valve in position thereon; Fig. 4:, a perspective of the annular valve Fig-5, a section on line XX, and Fig.6, .a section on line YY of Fig 1. Fig.7, a bottom plan of the valve illustrated in Fig. 3.
Referring. now more particularly to the drawing, the numeral 1 designates a section of tubing, comprising the Working chamber of the pump, having a lining -2,
of noncorrosive material, which extends from the lower end, to within a spaced distance of the upper end thereof.
A suitable inlet valve -3, is removably secured in the lower end of the working chamber by suitable means, that illustrated herewith is of the type well known in the art as a ball valve, and comprises a cage l and a ball 5 adapted to close on an inlet 6. lVithin the working barrel is a piston, or plunger 7-, having a central passage 8. The plunger is provided with a plurality of piston rings 9 and is surmounted by a domed cover, or cage 10 within which is a ball valve 1l, which controls the flow of fluid through the passage 8. Ribs 12,' which extend from the inner surface of the "cage 10 servet'o center the 'ball valve 11 and to limit its travel. Connected to theupper end of the cage 10, and in communication with the interior thereof, is a hollow piston rod 13- provided on its upper end with suitable means for the attachment thereto of a pump rod.
which may be extended upward to a point of connection with a suitable actuating force. The piston rodis provided, near its upper end, with a plurality of openings, or outlets, 15 the total area of which is equal to, or greater than that of the passage through the piston rod. A valve cage ,16 is positioned near the upper end of the working chamber. This valve cage composes an annular ring '17 disposed about the piston rod, and spaced from the sides of the tube 11 by lateral arms, or lugs, 18. Legs -l9 dependfrom oppositely disposed lugs 18 and are connected with an annular valve seat 20+ which fits snugly Within the tube 1 and is spaced from the piston rod leaving a passage ,2'7 therebetween. The valve seat 20 has a beveled seat -21 on its outer lower edge which contacts closely with an oppositely, disposed bevel face -22 on the upper end of the lining 2, forming a water tight connection therewith. The valve cage issecured in position by suitable means, such as screws 23, 24, which extend through the tube and engage respectively in the lugs 18 and the valve seat 20. A sleeve.,-25 adapted to ifit on the piston rod, has an annular enlargement 26 which seats on the valve seat 20 and forms a 'cut off valvewhich closes the passage 27. An annular flange 28- depends from the valve seat 20. A plurality of inlet openings, or ports -30 are disposed about the walls of the working chamber, opening into that portion which is above the plunger when it is at the upper end of its stroke, the flow of fluid therethrough being controlled by valves 31-- each of which comprises a body portion 82 the face of which is contoured to form to the curvature of the Walls of the chamber, and faced with a layer of suitable packing material 33, secured thereon by suitable means such as metallic plates 34.. The valves 31 are carried on the end of flexible members 35 which are secured by suitable means to the flange 28 on the inner surface thereof. In Figs. 3 and 7 I illustrate a modification of the upper valve cage 16, in which a plurality of legs 4S are employed, instead of the annular flange 28; the inner face of the legs L8 are curved transversely. The springs 35 are secured on the legs by means of bolts 50 and 5l positioned respectively on each side of the apex of said curved face. This construction affords means of adjusting the tension of the members 85. A delivery tube t0- is connected to the tube 1 by means of a reducing ring 41 It is to be observed that the passage through the plunger,
the hollow plunger rod, the outlet therefrom, and between the piston rod and the sides of the tubes are of substantially the same area as those through the foot valve and the side inlet valves, consequently as the space above and below the plunger is of equal capacitv there will be delivered on each stroke, up and down, of the plunger, an equal quantity of water, and, that this would be double the quantity that would be delivered by a single acting pump having a working chamber of the same diameter.
The operation of my improved pump is as follows: l/Vhen the piston is on the up stroke as illustrated in Fig. 1, water is drawn in through the foot valve 3 filling the lower portion of the working chamber, and water which is held in the portion of the chamber above the piston is forced upward, the pressure serving to close the side inlet valves 31 and to raise the valve 26 on the piston rod, as shown this opens up a free communication between the working chamher and the discharge tube through the passage 27. It is obvious that during this operation the ball valve 11 is forced down by the pressure of the water and closes the passage 8 through the plunger 7. When the piston is forced downward the pressure will close the foot valve 5 and the water beneath will be forced up through the passage 8, lifting the ball valve 11 and passing through the piston rod' enter the discharge tube 40 through the opening 15.
It will be observed that during the down- .upper part of the chamber is ward travel of the plunger the water in the discharge tube 40 is prevented from entering the upper portion of the working chamber by the closing of the check valve 26, which is held closed by the weight of water pressing down thereon. At the same time the refilled through the side ports 30. It will be seen that a continuous flow of water is maintained through the discharge tube during the operation of the pump. It will be observed that the arrangement illustrated permits of aready removal of parts for repairs and a d 'u stments.
Having thus described my invention so that anyone skilled in the art pertaining thereto may make and use the same, I claim:
