from the foregoing description, and the advantages of this screen over those previously known will be indicated briefly below.
The rings that are adapted to surround the perforated pipe may be made of brass, steel, or any other desired metal; and even glass might be employed, though it might not be very practical. As stated hereinbefore the Wire which is commonly employed must be of very soft material, but the rings used in connection with my improved screen may be made of the hardest material and. it is thus obvious that the possibility of their being Worn out or cut by sand erected on by the Waters in the well is greatly reduced.

Further, the manufacture of the screen presents the greatest simplicity, for the rings may be simply stamps from sheet material or, if preferred, they may be cast; and after" the rings have been formed it is only necessary to slip them on to the perforated pipe While they are in a heated condition, and allow them to cool. whereby they will be shrunk on to the pipe and thus not only be 'What I claim as new and desire to secure by Letters Fatent is:
