IMPROVEMENT IN WELL-TUBING.
Specification forming part of Letters Patent No. 208,619, dated October 1, 1878 application filed July 3,
To all whom it may concern:
Be it known that I, NOAH K. LUDLOW, of the city of Mobile, in the county of Mobile and State of Alabama, have invented a new and useful Improvement in Driven Wells, which improvement is fully set forth in the following specification and accompanying drawing, in which- Figure 1 is a side view. Fig. 2 1s a vertical section.
The object of my invention is to furnish a well-point which can be driven into the earth with little or no friction to the sides of the well-tube above it, and to enable the tube to be withdrawn Without breaking it.
My well-point consists of an inner strainertube, A, perforated with holes of a size in proportion to the diameter of the tube. The perforated portion of the tube A is covered with an unbroken corrugated brass wire-gauze, B, attached thereto, and the lower end of the tube A is inserted in a socket, E, of the cast-iron slip-point D. I make the point D considerably larger than the diameter of the Well-tube l itself, in order to relieve the latter as much as possible from friction in driving the Well. As the diameter of the point is greater than the diameter of the well-tube, it makes a larger opening in the earth for the passage of the latter. The socket E strengthens the tube A, and in cases where it is required to withdraw the well-tube from the earth, the slippoint D will become detached from the tube A and prevent it from being broken.
I prefer to make the tube A of brass or composition metal.
Having described my invention, I claim- The Well-point D, provided with socket E, in combination with the perforated brass tube A and unbroken corrugated brass wire-gauze, covering the perforated portion of tube A, said tube being detachably connected to the point, in the manner and for the purpose described.
