WELL ATTACHMENT.

SPECIFICATION forming part of LettersIatent No. 772,692, dated October 18, 1904.

nppncttion flied February 25,1904.. semi No. 195,303. (No model.)

citizen of the United States, and a resident of Mattoon, in the county of Coles and State of Illinois, have invented a new and Improved Well Attachment, of which the following is .a full, clear, and exact description.

My invention relates to attachments for wells; and its principal objects are to provide means for increasing the efficiency of the associated pumping Vmechanism and for th cleaning of the well-casing. l

v It consists in the variousfeatures and combinations hereinafter described, and more particularly claimed. L

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts lin both vfigures.

Figure l is 'a view of the `upper portion of a Well and pump embodying one form of my invention, part being in perspective'and partY in vertical section; and Fig. 2 is a vertical section through the lower portion of the Wellcasing.

"H designates the well proper or casing, to the lower end of which is attached a perforated strainer H, connected. tothe casing by a ring p, preferably of lead. VThe lower end of the strainer may be closed by the cap L.

`Into the casing fromv the upper end extends the suction-pipe G, reaching nearly to the lower end of the strainer, .having on its extremity the working barrel F, which' is held vin place at its lower end by a conical sleeve R,

conveniently of rubber, to which is attached a metal ring Jsupported by a collar I, riveted or otherwise secured near the end of the suction-pipe. lAdjacent to this sleeve R the suction-pipev end is inturned to form a seat with Which coacts a foot orv check valve K, and above this operates a Valved pistond E, carried bya working rod D.

Extending upwardly from the rod D is a piston-rodl C, passing through a stuing-box q in a bed-plate B and connected with the piston of what is here shown as a steam-cylinder A, but which evidently might instead be any suitable source of motive power, such as an electric, compressed-air, gas, or wind motor.

Upon the upper end of the casing H is a T-itting Z, and from this projectsl a nipple It, flanged at its upper end. Upon the adjacent end of the suction-pipe is a lange g, which extends over and rests upon the casingiange and serves to support the suction-pipe in place, at the same time furnishing the casing with an air-tight closure. Resting upon the liange g is a T-itting M, fianged at f and coacting with the under side of the bedplate.

From the lateral outlet of the T extends a discharge-pipe 0, in which is a check-valve P,

.provided with the usual air-chamber Q, it

being connected by short horizontal sections or'nipples N and R, a vertical section V, and an elbow U with a T W, one horizontal branch `of which furnishes the exit of the dischargeline, which would contain the usual means 4for shutting off the supply, while from the other nipples, X, Y, and Y., in which is a gate or. other valve Z, connects with the side outletotl the casing-Trl'. Into the section Y of the connecting-pipe opens an inlet-pipe y, while from the under side of the same section opens a drip or outlet pipe m. In both of these pipes may be closures or cocks n.

I Into the discharge-pipe beyond the checkvalve may be connected a pressure-gage T by a pipe s and into the casing a vacuum-gage K 'jby Aa pipe J.

In operation the rod D and its piston E will` fbe reciprocated at the desired speed by the n'connected motor, causing the foot-valve to raise and lower, drawing up'water through the foot-valve, and forcing it into the discharge-pipe through the check-valve, which prevents thereturn of the fluid. Owing to the air-tight closure between the casing and the suction-pipe, a partial vacuum will be produced therein upon the raising ofthe piston,

which results in a greater` draftof water through the strainer trom the surrounding soil than if the casing were open y at the top and the pump operating upon water under atmospheric pressure.

If the strainer becomes clogged, by opening the valve Z water may be forced back into the casing and out through the straineropenings, thus clearing it. The check-valve IOO P prevents the How of water back through the line 0. The pressure for this flow of water is gotten from the main discharge-line from elevated tank or through pumps connected thereto, or instead air, steam, or any fluid under pressure may be introduced through the pipe-line Y through an independently-connecting pipe-line y.

lf it is desired to learn whether there is any leakage of water from the discharge-pipe into the casing through the valve Z, it is only necessary to open the cock in the outlet-pipe m, which will show a flow therethrough should leakage exist.

The gages K and T permit the vacuum in the easing and the pressure in the dischargepipe to be read at will.

It will be obvious that a considerable increase in efficiency will result from the production of the vacuum within the casing and that it will also avoid the waste of power in pumping air, as is liable to occur when the well is open at the top. Moreover, the ready and effective means of keeping the casing free also adds to the pump efficiency.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination with a well-casing having at its top an air-tight closure and communicatingat its lower end with the surrounding soil, of a suction-pipe extending into the casing, and pump mechanism associated with the suction-pipe.

2. The combination with a well-casing having a perforated end and furnishing an extended chamber above the perforated portion, of a su etion-pipe therein, a piston operating in the suction-pipe, and means for creating a partial vacuum in the casing upon the upward movement of the suction-pipe.

3. rlhe combination with a well-casing having a perforated end and furnishing an extended chamber above the perforated portion, of a suction-pipe extending through said easing, means for closing the top of the casing against the entrance of air, a discharge-pipe leading from the Lipper end ol the suctionpipe, check-valves in the lower end ol the suction-pipe and in the discharge-pipe, and a valved piston operating in the suction-pipe.

il. The combination with a well-casing coinmunicating at its lower end with the surrounding soil, of a suction-pipe therein, a piston operating in the suction-pipe, means for creating a partial vacuum in the casing upon the upward movement of the piston, and a vacuum-gage connected with the casing.

5. The combination with a wellcasing closed at the top, of a suction-pipe entering` the casing through the closed top, and an independent pipe leading into the easing.

6. The combination with a welleasing closed at the top, of a suction-pipe entering the easing through the closed top, and a pipe connecting the casing and the suction-pipe.

7. he combination with a wellcasing closed at the top, of a suction-pipe entering the casing through the closed top, a pipe connecting the easing and the suction-pipe, and a valve in the connecting-pipe.

8. The combination with a well casing closed at the top, of a suction-pipe entering the easing through the closed top, a pipe connecting the easing and the suction-pipe, and a pipe opening from the colniecting-pipe.

9. The combination with a wellcasing closed at the top, of a suction-pipe entering the casing through the closed top, a pipe connecting the casing and the suction-pipe, and independent inlet and outlet pipes opening into the connecting-pipe.

1n witness whereof l have signed my naine to this specification in the presence of two subscribing witnesses.
