IMPROVED WELL-POINT.

T0 ALL WHOM IT MAY. CONCERN:
Be it known that I, HENRY Gr. CADY, ofthe city and county of St. Louis, Stateof Missouri, have invented a new and useful improvement in Well-Points; and I do hereby declare the following to be a full aud exact description of the same, reference being had to the annexed drawing, with letters marked thereon.
Figure l in the drawing `consists of a'transverse half section of my well-point, showing the interior thereof.
B is a cast-iron point, with a groove in it, to receive a-small peg protruding from the inside of the pipe A, which prevents the Apipe from turning on said point; this point is also furnished with a screw-thread and shoulder, to ft in the thread and shoulder of the band H, as seen inthe drawing. K is a. perforated tin tube, bent at its lower end so as to be held permanently between the shoulders of H and B, as shown in the drawing, and
Vprovided at the upper end with a. fold bent outward, so asY to engage a similar fold on the inside of the tube P.-
These welts may be seen at N. P is a metallic tube or sleeve fastened at the upper end to the pipe A, between a shoulder on the pipe and the socketR. At the lower end it is provided with a welt that is bent inward, to engage a similar one ou the tube K. This tube serves to protect the screen and withdraw the point. A is a piece of gas pipe that passes inside the tubes K and P, and rests with its lower end on the upper-.shoulder of B, while the point is being driven. Also, the upper end of this pipe A is furnished with a thread to operate in the threadof the socket R, and also with asmall shoulder to fastenthe upper end of the outside tube or sleeve permanently to the pipe A. The socket R is provided'witha. thread in the upper end, so as to fasten on additional pipe. It will' be remembered that K is inside of the tube P, and that A is inside of the tube K, and thatP is made fast at the upper end to A, as 'above described, leaving room for K to pass up between P and A. Also, that K is made fast', to B by screwing the shoulders of B and PII together, as above described.
The advantages of my invention over others are, lil-st, the cheapness and simplicity of its structure; second, the screen -being outside the pipe, gives a much larger surface for the admission of water; third, the groove and peg prevent the pipe from turning while additional pipe or the pump is being attached; fourth, the point has sharp edges to facilitate its driving. I
Now, what I claim as my invention, is
The manner of connecting the tube K to the point B, and the tube P to the pipe A, and to each other, as
HENRY G. CADY.
