Hydraulic Well Drill.

Hydraulic Well Drill.

This drill, patented by Charles H. Oxley, Norfolk Neb., is intended for boring wells for water in earth etc. The drill tube is provided with a hollow auger point A. constructed of the form shown, so that the water can pass through it. its upper tubular end being formed with a screw thread, while the lower end of this hollow cutting point is enlarged and divided by equally distant slits, the sections thus formed being twisted so that their straight free lower ends meet in radial lines extending at right angles to each other, as clearly shown in the drawings. To the upper end of this auger is connected by a coupling C the screen tube B of the usual construction, and the upper end of this screen is connected by a coupling I) with the lower end of the well tube when the well point is to be used. E indicates a water tube, on the lower end of which is secured a circular valve plate, the central opening of which is closed under upward pressure by a downwardly opening valve. The valve plate is of such size that it will fit against the lower end of the screen tube, and upon the upper end of this tube fits a valve plate, having a central a; erture through which the upper end of the water tube E passes, and having four ports or openings II formed in it as shown. Upon the upper side of the valve plate rests a leather valve, and the water tube and valves are all held firmly in position by a binding nut. The valve plates are preferably formed of brass, so as to be noncorrosive.

In operation the motor liquid or water used in sinking the drill is forced from the surface by a force pump through the well tube, when its downward pressure closes the valve and forces it to descend through the central water tube, when it will open the valve at the lower end thereof and be forced out through the hollow auger point, thus removing all dirt from the auger and passing up to the surface around the outside of the well tube. When the desired water is reached by the boring auger the force pump is stopped and the pressure of the water from below will close the valve, thereby preventing sand, etc., from passing up through the central tube, the water entering the well passing up through the screen tube, opening the valve at the upper end thereof and rising up through the well tube, as will be clearly understood.

ANOTHER KIND OF FIRE Escape.—Guest : I’m glad there is a rope here in case of fire ; but what’s the idea ol put ing a Bible in the room in such a prominent position ? Bell boy : Dat am intended foil use, sah, in case the tire am too far advanced fob you to make you escaj>e, sah.
