RECIPROCATING PUMP.
Application filed August 5, 1922.
ci n'ocatin Pum i. of which t e followin D is a specification, in such full and clear terms as will enable those skilled in the art to construct and use the same.
This invention relates to a pump, and its object is to produce a pump which is capable of throwing a steadier stream of water than the ordinary reciprocating pum-pcan throw, by reason of the'provision it has for the production of two balancing air chambers within the pump which makes it more evenly operated than the ordinary reciprocating pump, and which cause a more uniform flow of the water therefrom.
Other objects of the invention will appear as the description proceeds.
An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be modifications thereof.
Fig. 1 is a view partly in a vertical section of the complete pump.
Fig. 2 is a plan view of the complete pump.
Fig. 3 is a horizontal sectional view of the complete pump on the line 33.
Fig. 4 is a detail illustrating the mannerof securing one of the gaskets inside the pump cylinder. 7
Fig. 5 is a vertical sectional view of a modified form of the pump in which the pump plunger consists of the tubular member extending to the surface of the well, and which is balanced by the admission of air thereinto.
Fig. 6 is a plan View, in section, of the lower portion of the pump on the dotted line 6 6, Figure 5.
The numeral 1 indicates the suction pipe which is connected to the pump ba rel 2 by means of the cap 3, said cap carrying two inwardly opening valves 1 and The pump barrel is closed at the top and has the discharge pipe 6, although, if the pump is to be used in a small, deep well, the discharge pipe 6 may extend stralght up equally as well.
l/Vithin the lower portion of the cylinder 2 there is an annulus form of an angle bar, as
Serial No. 579,877.
shown at 7, This annulus is connected to the cylinder by means of suitable screws 8 to carry a packing gasket 9 which secured thereto by means of the ring 10 and screws 11 (see Fig. l).
Inside the upper portion of the cylinder there is a second cylinder 12, closed at the top. This cylinder is supportedat a fixedv distance from the top of the pump cylinder 2 by means of two rods 13 and 14, and said cylinder supports a transverse disc 15, bv in ans ot' the two rods 16 and 17. These two rods pass through the top of the plunger 18, there being no attempt to make the rods and plunge-r top any tighter than enough to obstruct the flow or air suiiiciently to carry out the objects of the pump.
On the top of the plunger there is the gasket or washer 20 which bears on the inside of the cylinder 12. The bottom of the plunger 18 is closed by means oi the can 21, which has the two inwardly opening valves 22, 23. The plunger is also provided with two large openings 2 .1., above the level of the gasket .9. The plunger is reciprocated by means of two hollow rods 26, 2? which pass through stufiing boxes 28, 29 at the topot the cylinder 2. These two rods are connected to the periphery of the cylinder 18, and under normal operation, a. sutlicient quantity of air is forced through the rods 26, 27 tosubstantially fill the cylinder 12, and any loss of air by absorption is made up, from time to time, by pumping more air through the pipes 26, 27 and allowing it to pass into the air-chamber through a tube 30, which has a very small opening therein, and through very small openings 31, 32 at the top of the pump plunger.
It will be seen that whatever maybe the water pressure within the pump that an equivalent pressure will be brought to bear upon the .air within the air-chamber above the plunger, and in the air chamber formed by the top of the, plunger and the partition 15 in conjunction with the partition 15 carried by the plunger itselt.
In the operation the plunger will be raised and lowered its present position being such as to requireitto be lowered. This will compress the air in the plunger chamher more than it is at the time when the pump starts to operate, and as the opening between the two chambers is very small, it cannot quickly equalize, but will cause the plunger to operate as though it were operating between two heavily stressed springs with the result that any downward movement is met immediately thereafter by a tendon oi the plunger to rise, and a slight upward movement of the plunger will cause it to rise above its point of rest, and this action will be repeated as longas power is applied. to the pump, the two air chambers acting as butl'ers to cause the plunger to surge back and forth at each end of its stroke and deliver a .steadier stream of water than is delivered from the ordinary reciprocating pump.
it: is to he observed that in its present position the plunger is ready to move down to the can of its stroke, at whiehtime the valves 4: and IS ill be closed. The valves 2:2, 253 will be open and the liuid will be forced through the openings it will e apparent to those skilled in the art that several of these cylinc ers may be cou filed together and used in tandem it that is desired.
in liigure 5 there shown a slightly modified form oi the invmition. in which the well casing is 'indi atei'l at 40. This well casing may be of any form, and the pump cafn is indicated at a l.
The pump casing has a titting l at its lower end, which carries a pair of inwardly opening valves 4-3, 4:4, and the fitting 42 carries a suction pipe At a suitable place close to the valve 43, it, there is a ring 4:6,.seeured within the pump casing 41 which carries a packing H, which bears against the tube 48. This tube has a cap at its lower end, and has two inwardly opening valves 50, 51, therein.
This tubular member is connected to another tubular member, or another series of to )ular members by means of the coupling 52 at which coupling there is a partition 53 so that an air-tight chamber is formed in the upper portion of the tubular member 1-8, but has holes therein to permit the water pumped to be discharged from the tube 48.
A tube 55, of any suitable length, is connected to the coupling 52, and it has a hole as at its lower end adjacent the partition 53. it the upper end the tube has a zap 57 .hrough which a pipe 58 intends and which ipe also extends through the partition 53 t its lower end.
The cap 57 also has a pipe 59 connected therewith to supply the tube with air, and the cap 57 is also connected by the link 00 with a suitable reciprocating arm 61 for the operation of the pump.
The tubing to and 55 is sutiiciently light to allow the air that is placed within the tubing to counterbalance the vvight of the entire body oi reciprocaing part". This is acct'nnplished by using light boiler tubing and a quantity of air is supplied to the chambers. formed by the pipes 48 and 55 which will j: :t balance their weights.
ln operati i, as the pump plunger is reciprocated, the rater will lill the pipe ell nd run out the pipe 62. fit the same time the pressure 01 water within the pipe 4-1. will be applied to the air within the tube 13 ant within the tube 55 with the result i d air will be under th same press the pressure ot the column of water.
As tne pump plumer is reciprocated, the air contained within said plunger will be subjected to varyin pressures and this varying pressure will cause the water to surge in and out of the tube 48 and the tube 5.3 and cause a substantially uniform delivery ohwater iron the pipe 62.
l vhat l ch im is as follows, but various 1 be made in the construcmodifications 11 a tiou shown in the drawings and above partiicularly described form, within the purview of my invention:
1. In a pump, the combination of the pump cylinder, a secondary cylinder inside the same, a hollow pump plunger movable within the second cylinder and within the outer cylinder, the secondary cylinder and pump plunger forming two air chambers for balancing the operation of the pump plunger and valves to allow the discharge of the fluid through the hollow pump plunger.
2. In a reciprocating pump, a pump cylinder, a hollow pump plunger therein, a second cylinder within which said plunger is also movable, and forming therewith a pair of air-chambers adapted to hold air at the pressure of the water being pumped to aid in reversing the pump plunger at each end of its stroke to deliver a steady stream of fluid.
3. In a reciprocating pump, a pump cylinder, a hollow pump plunger therein, a secondary cylinder within which the pump plunger operates and forming with it a pair of air chambers to hold the ai at the pressure of the water being pumped to balance the pump plunger, and valves to allow the liquid being pumped to pass through the pump plunger.
In testimony whereof I have hereunto set my hand this 15th day of July A. D.
