Specification of Letters Patent.
Patented July 2, 1907.
Original application iiled May 13,1905, Serial No. 260,276. Divided and. this application filed August 2 2, 1906. Serial No. 331,587.
To all whom it may concern.'
Be it known that we, HENRY NAGEL and JOHN E. NAGEL, citizens oi the United States, and residents oi Brunswick, in the county of Antelope and State o Nebraska, have invented a new and Improved Pump, of which the following is a full, clear, and exact description.
This is a divisional application of our application for pumps, serially numbered 260,276, filed May 13, 1905, and relates to driven or deep well pumps, in which a vmetal casing fixed in the earth has an inner lining in Which the piston reciprocates, and in the lower part of which lining is iixed an upwardly opening check valve.
Our invention consists in a simple' attachment to this orm oi pump, whereby either a vacuum or the pressure of an air cushion is made to promote the continuity o the up-low of water, as hereafter more fully described. v
Reference is to be had to the accompanying drawings forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure l is a sectional View of a driven well having our attachment applied and acting as a vacuum chamber, and Fig. 2 is a iragmental view of the casing, lining and piston rod, showing our attachment connected to the top of the piston and acting as a compression chamber or air cushion.
In the drawing, Fig. 1, l is a well casing having an inner lining tube 2 within which operates the piston 3` having an upwardly opening valve 4 and a piston rod 5 `rising to the surface.
Below the piston and carried by the stationary packing ring 6, is the usual casing 7, supporting an upwardly opening check valve 8. The lower extremity oi this check valve casing 7 is screw-threaded internally to receive our attachment. This consists of a cylinder 9 screw-threaded both at its upper and lower ends, and across which near the top is a partition 10 dividing it into an upper and lower chamber. tion 10, openings 1l in the side walls of the cylinder connect the annular space formed between the cylinder 9 and the outer casing with the interior of the check valve casing, while below the partition l0 openings l2 lead from said annular space into a vacuum chamber 13 situated below the partition 10.
With a pump equipped with our attachment, the operation is as follows: When the piston 3 rises, air is Above the partifirst drawn out of chamber 13 and then water follows and is drawn up through the check valve 8, said water passing up from the well through the annular space around the cylind'er 9 and through the openings ll. As soon as the air is exhausted from chamber 13, only water then rises,'and the suction o the piston above produces at the same time a suction and partial vacuum in the chamber 13. Then on the downward movement of thepiston, when the checkvalve 8 closes, the Vacuum in chamber 13 will assert the suction effect and cause the water to continue to enter the well tube. This is oi special value when the water has to pass through small holes in the well tube or point, or when the iniiow of water is small, since it prolonge .the in-flow oi water through the period of time when the piston is descending as well as when it is rising.
In Fig. 2 we show exactly the same construction of cylinder 9 with partition 10 and holes 11 and 12 above and below the partition. The cylinder 9 in this case, however, is attached to the topof the piston 3 and between the same and the piston rod 5, and when the piston descends the water rushes up through holes 11 and 12 and compresses air cushions above the holes l2 and 11, which in expanding orce the water up around the cylinder 9 past the piston rod 5 to prolong the'up-flow above the piston.
Having thus described our invention we claim as new and desire to secure by Letters Patent:
1. An attachment for pumps, consisting of a cylinder having a partition across it with openings above and below said partition, and a screw-threaded upper end adapted to connect either with the check valve casing or piston rod to form a vacuum or compression chamber.
2. An attachment for pumps, consisting of o. cylinder having a partition across it with lateral openings above and below the partition, and a screw-threaded upper and lower end adapted to be connected between the piston rod and piston o1' to the check valvel below the piston to form a vacuum or compression chamber.
3. An attachment for pumps consisting of a cylinder having a partition across it with openings above and below said partition, in combination with the pump casing and check valve casing and stationarily connected to the check valve casing below the check valve to form a vacuum or compression chamber.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
