SAMUEL XV. DOUGLASS, OF NE YORK, N. Y.
POINT FOR DEEP WELLS.
SPECIFECATION forming part of Letters Patent. No. 340,035 dated April 13, 1886.
(No model.)
T0 at] whom it may concern.-
Be it known that I, SAMUEL W. DOUGLASS, of New York city. New York, have invented a new and useful Improvement in Points for Deep \Vells, of which the following is such full, clear, and exact description as will enable others skilled in the artto make and use the same, when taken in connection with the accompanying drawings, in which- Figure 1 is a perspective view. Fig. 2 is a vertical section. Fig. 3 is a horizontal crossseetion at 9000. Fig. at is a horizontal cross section at y y.
Like letters indicate like parts in all the drawings.
This invention relates to apparatus and method of sinking deep wells in gravel, sand, or quicksand by means of a pipe or tube through which a continuous supply or flow of fluid is maintained; and it consists of the contracting end or point attached in the tube, so that it is adjustable and removable by a rod passing through the pipe or tube to which it is attached, and the various combinations hereinafter specified and claimed.
My invention herein set forth and claimed is intended to be used with and to be an improvement on the devices described in Letters Patent No. 288,557, to J. P. Edson, November 13, 1883, and Letters Patent No. 299,546.
The present invention is more applicable to boring wells or deep shafts by means of tubes or pipes sunk in sand or quicksand by means of a flow of water or other fluid down the pipe being sunk in a continuous manner to a rock or other hard obstruction, and boring through the rock or obstruction by a drill passed through the pipe or tube.
To the lower end of the tube G is secured a shoe, A, preferably of the same outward diameter as the tube. The internal bore of the shoe is slightly less than the bore of the tube. The tube and shoe are joined to one another by means of proper screw-threads on the shoe to fit the threads E in the end of the tube. On the interior of the shoe A is a left-hand thread, 0, which thread extends the entire length of the smaller bore of the shoe. A head, B, pointed at one end, and having holes F F through it, and the chamber or socket at the other end, in which is the thread D, to receive the drill-rod H, is provided on its exterior greatest circumference with a thread to fit in the interior thread of the shoe A. This thread extends throughout the entire length of the greatest circumference of the head B. The drill-rod H has at its lower end a right-hand screw-thread, D, which fits in the thread in the recess or chamber in the head B. The threads between the shoe A and tube G are left-hand, and between the drill-rod H and head B are right-hand. The thread between the shoe Aand head B isleft-hand, so that when the drill-rod is turned into the head so that the shoulder on H abuts the shoulder on the head B a continuance of turning in the same direction will screw the head B up through the shoe A, and free it from the shoe.
The shoe may be secured to the tube or'casing by a screwthread, either right or left hand, if provided with a key to prevent the shoe turning with the turning of the head B in it, or the shoe may be keyed or brazed on the tube, without departing from the nature of my invention.
The mode of operation is as follows: The shoe A and head B are secured to one another at the screw (J, and the shoe A to the tube or casing at the screw E. A flow of water is maintained through the case or tube downward and out at the openings F F in the head B, which makes a passage through the soil or gravel into which the lower end or head B is placed, so that the tube sinks into it, and continues to sink until rock is reached, when the drill-rod H is put in the case or tube G, and water is supplied at the upper end of the drill-rod, and the drill-rod is screwed into the head until the shoulder-on it comes against the shoulder on the head, and turns it so as to screw it up from the end of the shoe out of the thread 0. A continuous flow of water is thus maintained through the openings F F. The head may now be raised with the drillrod through the casing, when a drill-rod with a boring-head should be inserted in the casing, and the rock at the bottom bored thereby. A water-flow should be maintained through the tube G and shoe A when the rod H is withdrawn, to prevent a return of the washed-out sand or gravel during the change of drills.
What I claim as new, and desire to secure by Letters Patent, is-
l. The combination, with a well casing 0r i tube, of a shoe, A, having an internalscrewthread of slightly less diameter than the internal diameter of the well casing or tube,substantially as described.
2. The combination, with a well casing or tube, of a shoe having an internal screw-thread of slightly less diameter than the internal diameter of the well-casing or tube, and anozzlepoint having an external screw-thread fitting in the internal screw-thread of the shoe, substantially as specified and set forth.
3. The combination, in a nozzle-point, of an external screw thread, 0, and an internal screw-thread, D, in the chamber, one thread being in the opposite direction from the other, I 5 substantially as specified.
4. The combination, with a well casing or tube, of a shoe having an internal screwthread, a nozzle point having an external thread to correspond therewith, and an inter- 2o nal thread in the chamber in a reverse direction from the external thread, and a. drill-rod having an external thread corresponding with the internal thread of the nozzle-point; I S. W. DOUGLASS. \Vitnesses:
