I Letters mentira-110,136, dated December 13, 1870.


The Schedule referred to these ,.Lett-ers Patent and making part of the To all Iwhom, it may conce-rn.:

Be it known that I, GEORGE W. HEMENwAY, of

Elmira, in the county of Ghemung and State otf New York, have invented a newand valuable Improvement in NVells; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had 'tothe annexed drawing making apart of this speciication, and to the letters and figures or" reference marked thereon.

Figure 1 ofthe drawing is a sideI view of my inven tion.

Figure 2 is a central vertical section thereof.

Figure 3 is 'a top view of the cylinder with the uppelhead removed, showing the strainer.

My invention-has relation to means for keeping the pump and tubes of a driven well clear of sand; and

It consists in the construction and novel arrangement of a sand reservoir with strainer and valve.

The bottom of the reservoir is made easily removable, for the purpose of affording 4a ready'means of cleansing out the deposits of sand The letter A of the drawing designates the cylin drical body of the sand reservoir.

VB represents the upper cylinder-head duly bolted thereto, through suitable anches or lugs b b and @represents the lower cylinder-head bolted to the cylinder in a' similar manner, and arranged to be easily removable when it is desired to empty the reservoir of the accumulated sand.

D represents the collar into which the dischargepipe is screwed.

E represents the opening in which the inlet-pipe is secured. This opening is in the side of the cylinder, near the top.


cylinder, and against the inlet orifice, in such a mannerfas to permit the free inward flow of the water, but

instantly closing the orifice whenever, from any canse, a retrograde flow sets up.

`By this means the supply-pipe is also kopt free from any undue )roportionof sand.

The operation ofiny invention is as follows: lVater, carrying sand and other extraneous matter,

chamber much `ot thesand will be deposited, the water therein being in a state of con'1par.ttive rest. lint those particles of sand, &e., which may not have had time to settle, are prevented from being carried by the upward iiow of' the water into the pipe l), leading sand into the pipe E, thus keeping it free.V

The strainer may be reached for cleaning purposes by removing the upper head'of the cylinder.'

I claimlet and outlet orificesl at or near its upper end,`the strainer F, valve G, and removable top and bot-tom C,

in the manner and for the purpose speciliet f In testimony that I claim the above, I have here-- unto subscribed my name' in the presence of' two wit- F represents a perforated plate or strainer secured between the upper edge of the cylinder and the upper cylinder-head. This strainer serves to prevent the sand from passing upward through the discharge-pipe.

G designates a valve, arranged on the inside ofthe nesses.



as isusnal in driven wells, flows upward through the pipe E and valve, G into the reservoiigA. ln this,
