Specification forming part of Letters Patent No. 174,!80, dated February 29,1876; application filed To all fiuhom it may concern:

Beit known that I, EDWARD FRANK AN- DREWS, of Augusta, in' the county of Rich- .mond and State of Georgia, have invented a come partially filled with sand, mud, or other foreign substances or impurities. f

The object of my invention is to provide an improved. pump' for removal of the same,

without at the same time removing the water from the well. To this end I adopt the construction'and arrangement'of parts hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a sectional elevation of my improved pump; Fig. 2, a plan view of the bottom thereof. Fig. 3 is a sectional elevation of a sand-chamber of modified construction.

rPhe barrelof the pump is formed of two parts-the piston-chamber A, and sand and mud chamber B-which are connected by flanges a and screws b. A cloth or wire-gauze strainer, C, is clamped and conlined between the parts A B, the same forming the top of the latter B, as shown. The centrally-apertured piston D is provided with 'a ball-valve,

E, which is inclosed by a wire guard, F, but

has entire freedom of 4movement within the same, so as to alternately open and close the opening in the piston, as the piston reciprocates. The plunger or piston-rod is provided with a ring, c, for attachment of a chain or- February 2, 1876.

ber, are arranged within the sand and mud chamber B, -the same being set vertical in the circular rim or baseof the chamber, and. being in length about two-thirds the height of the chamber. rIhe bottom of the chamber is closed by a hinged bottom, I, secured by slidebolts h.

It is evident that when the pump is lowered' into a well containing sand, mud, and other solid foreign matter of such a nature as enables it to pass up the tubes lH, and the piston is then raised, the vacuum thus created will cause the sand or mud, Src., to be vtaken up and enter the tubes H along with the water. The sand or mud will be arrested by the strainer, and thus be deposited in the chamber B, while the water will raisethe ballvalve, and pass through the piston upon its descent.

This operation may be continued until the chamber B has become lled with sand or hinged bottom. The sand or other sediment' received into the chamber is also more readily discharged from the chamber than would be the case if a single large tube were arranged in the center of the chamber.

The water which passes through the strainer is forced out of the top of chamber A, and thus returned to the well.

- The modified form of the bottom of the sand-chamber, Fig. 3, is concave, so that the same will tend somewhat to exclude the water and concentrate the body of sand which it is desired to draw into the pump, thus materially facilitating the action of the pump.

It is of course necessary that the piston-rod or piston shall be constructed of material having sufficient weight to force the piston down when tension is removed from the hoisting-cord. Y

The piston-valve should also be of stone,

metal, or other material .of greater specific 2.
