POINT FOR WELL-SINKING MACHINES.
SPECIFICATION forming part of Letters Patent No. 436,889, dated September 23, 1890. Application filed May 10, 1888- Serial No. 273,420- (No model.)
To all whom it may concern.-
Be it known that we, JOSEPH R. COFFIN and WILLIAM 13. Comm, both of Bliss, in the county of Wheeler and State of Nebraska, have invented a new and Improved Point for Well-Sinking Machines, of which the following is a full, clear, and exact description.
The invention relates to a well sinking machine for which we filed an application for United States patent on the 19th day of No vember, 1887, and under the Serial No. 255,568.
The object of the invention is to provide a new and improved point adapted for wellsinking orprospecting machines which isvery simple and durable in construction and automatic in operation, permitting a free downward flow of the water while the well is being sunk and a free upward flow of Water when the well is completed.
The invention consists of aperforated tube carrying at one end a drilling-tube, of a pipe held within the said tube, and valves held on the top and bottom of the said pipe.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional side elevation of the improvement. Fig. 2 isa sectional plan view of the same on the line no a: of Fig. 1. Fig. 3 is a plan view of the upper valve. Fig. 4 is a sectional plan view of the improvement on the line y 'y of Fig. 1, and Fig. 5 is an inverted plan view of the same on the line z of Fig. 1.
The well-tube A carries at its lower end a collar .13, in which screws a tube 0, provided with a suitable number of apertures D, and carrying. at its lower end a collar E, in which screws the drilling-tool F of any approved construction. Between the upper end of the drilling-tool F and the lower end of the tube 0 is held a block G, which closes the lower end of the said tube 0, and carries an upwardly-extending pipe H, passing throughout the length of the tube 0, and supporting .at its upper end a disk I, closing the upper end of the tube 0, and provided with a number of apertures I, closed by the valve J, preferably semicircular in shape and fitting over the central pipe H. The valve J is held in place by awasher K, which is in turn held in place by a pin L, passing through the upper end of the central pipe H. Other means may be employed for holding the valve J on top of the disk I.'
On the lower end of the tube H is held the valve N, opening downward and secured to the bottom of the block Gr.
The operation is as follows: When a well is to be sunk, the well-tube A is turned in the usual manner, and the water under pressure is passed down the said tube A. The water from the latter passes through the central pipe H and opens the valve N, and then flows to the drilling-tubeF in the same manner as described in the application above referred to. When the watervein is struck, the turning of the tnbeA ceases and no more water flows down the said tube, as before described. The pressure of the water from the water-vein causes the valve N to close, and at the same time water passes in through the perforations D in the tube 0 and flows upward through the apertures I in the disk I and opens the Valve J upward, so that the water from the water-vein passes into the tubing A, and is lifted upward in the usual manner by a pump or other means. Thus it will be seen that the point is automatic in operation, as no device is necessary to make a connection between the tubing and the water-vein. It will further be seen that no part of the wellpoint is to be removed after the water-vein is struck. All that is necessary for the operator to do is to cease boring and to connect his pump or other device with the tubing A for lifting the Water.
Having thus fully described ourinvention, we claim as new and desire to secure by Letters Patent 1. In a point for wellsinking machines, the combination, with an outer perforated tube having an internal annular upward opening valve above its perforations, of a smaller concentric inner pipe extending at the ends beyond the said perforations, and having a downwardbpenin g valve at. its lower end, the
space between the said two pipes below the peripheral portions resting on the ends of the perforations being closed, substantially as outer pipe, whereby when the outer pipe is described. coupled the blocks and inner pipe will be 2.
