SAN D-PUMP.
SPECIFICATION forming part of Letters Patent No. 241,089, dated May 3, 1881.
Application tiled September 9, 1880.
To all whom it may concern:
Beit known that I, THOMAS MALcoLMsoN, a citizen of the United States, residing` at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in SandPumps; and I do hereby declare the following` to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to letters or figures of reference marked thereon, which form apart of this specitication.
My invention relates to sand-pumps for use in boring oil and other deep-bored wells.
My invention consists in providing` a sandpump which will remain closed until itreaches the bottom of the well, when it will open at the bottom and receive the miXed water and borin gs or sand by means ofthe pressure of the column of liuid above it. I accomplish this end by placing in the bottom ofthe pump a valve which opens outwardly therefrom, and which has a stem extending upward through or by the pump, and to which stem the operating-cord is attached, whereby the said valve is kept closed whenever the pump is held in suspension by said cord, but will open whenever the pump is seated on the bottom of the well or on the ground and the operating-cord is slackened. The necessary adj uncts ofthis construction are, first, a cage or chamber at the bottom of the pump into which said valve can drop and through which the fluid to be elevated can enter the pump-barrel 5 second, means for preventing the fluid entering the top of the pump, and, third, means for permitting the escape of air from said pump-barrel when the fluid is entering it. All of these adjuncts are susceptible of various modiled constructions, some of which will loe pointed out in the following specification, but whatever construction may be adopted the essential feature of the device will remain the sameviz.,a valve in the bottom of the pump-barrel opening outwardly therefrom, and which is attached by its stem to the operating-cord in such a manner that the said valve will be closed when the pump is held in suspension by said cord and will open when the pump is seated upon the (No model.)
bottom ofthe well or the ground and the cord is slackened.
My device is shown in lthe accompanying drawings, as follows:
Figure l shows the pump in vertical section and the valves and stem in elevation, said parts heilig in the position they occupy when the pump is suspended on the cord. Fig. 2 is a like view with the parts in the position they occupy when lthe pump is seated on the bottom ot' the well or on the ground.
In the drawings, A is the pump body or barrel.
B is the valve rod or stein.
C is the cage or chamber at the bottom of the pump.
E is the valve at the bottom of the pumpbarrel, which opens outwardly therefrom and into the cage O.
l) is a second valve, placed on the valve-stem B, and serves to close the top of the pumpbarrel.
E and D are the seats of the s iid valves, of which E is formed on the nipple I, which connects the pump-barrel and cage, and D' is formed on a cap, H, which screws into the top of the pump-barrel.
F is a flange on the valve-stem B above lthe top ofthe pump, and which closes the opening through the cap H when the parts are in the position shown in Fig. 2.
G is a loop on the valve-stein, to which the operatingcord is attached.
The valves D and E are so adjusted on the valve-stein B that both will close upon their respective seats simultaneously. Consequently, as the pump is being lowered into or drawn from the well by the cord, the valves are closed, and no uid can enter either at the top or bottom until the pump is seated and the cord slackened; but as soon as the pump is seatedfor example, at the bottom ofthe wellthe two valves drop down, the valve D into the pump andthe valve E into the cage. When this occurs the flange F covers the opening in the cap H and prevents a rush of Water in at that point, and as the passage into the pump is opened below and thepressure of iiuid is greatest at that point the rush of water will be through that point, and the air will be driven out past the ange F. If the flange F is pro vided with a packing-washer, as shown in the drawings, the escaping air will have to slightly lift the valve-stem to escape. I do not think the washer will be necessary in order to exclude the water from entering the pump at the top, as the pressure at the bottom is greatest and the outgoing air will prevent the water coniing in. It', however, it is found necessary to keep the top of the pump shut tight, the washer may be used, and if any further escape for the air is required a check-valve opening outward may be formed in the cap H, or the valve-stem may be made hollow and a check-valve be placed in it. The cap II may be made to fit close upon the stem, and a stufling-box be used for it to pass through and a clieck-valve for the escape of air be employed. In that case the valve D can be wholly dispensed with.
Where the two valves D andE are used, one should, perhaps, be made of iibrous or yielding material, like packing, so as to insure a perfect seating ot' both valves simultaneously. Sand pumps are often twelve or more feet in length, and by variation of temperature the valve-stein may often vary in length slightly, and this variation would be taken up it'one or both of the valves were made of yielding material.
In the drawings I show the lower valve as adjustable upon the valve-stem by a screw cut on the stem and ajuin-nut to secure it at any point desired, so as to insure the simultaneous seating ot' the two valves.
The cage C may be made without a bottoni, or the bottom of it maybe pointed downward like a cone or like a chisel, so as to enter the and water rush into the pump-body, the force acting being the pressure of the superincumbent Huid. The pump should only rest at the bottom long enough to lill, which is only an instant, When it should be drawn up. While being drawn up the valves are closed the same as when going down. Vhen the top is reached and the pump is seated upon the ground the valves open and it empties.
My device serves equally well as a sandpump and as a bailer.
What I claim as new is- 1. In a sand-pump for oil orotherdeep-bored wells, the combination, substantially as shown, of a pump-barrel having a valve-seat in the bottoni thereof, a valve seating upon said valveseat and opening outwardly from said barrel, a valve'stein connecting said valve with the operating-cord and serving as a handle or bail to said pump, a cage or other chamber attached to the bottoni of said barrel to receive said valve when open, and through which the liquid passes into the pump-barrel, and means, substantially as described, for excluding the water from the top of' the pump and for permitting the air to escape from said pump at the top when being filled.
2. In a sand-pump for oil orothcrdeep-bored wells, the combination ofthe barrelA, having valve-seats D and E therein, a valve-stem, B, having valves D and E, iiange F, and attaching-loop G thereon, a cage, U, attached to the bottom of said barrel A, into which the valve E enters when open, and through which the. fluid passes into the pump, all being substantially as and for the purposes set forth.
In testimony whereof I aiiX my signature in presence ot' two witnesses.
'THOMAS MALCOLMSON.
