` IMPROVBD FETERING TUBE FOR WELLS.

TO ALL WHOM 1T MAY GONCERN:

Be it known that I, QHARLES C. COLE, of Northfield, in thecounty of Washington, and State of lVermont, have invented a new and useful improvement in Filtering Tubular Wells; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side view of the lower part of' the well tube, the hinged plate being turned up or opened.

Figure 2 is a vertical longitudinal central section of the same, showing two ways of protecting the countersunk strainers.

Figure 3 is a cross-section of the same, taken through line :i: rv, g. 1, showing the countersunk strainers protected by hinged plates. f'

Figure 4" :13 cross-section of 'che same, showing the countersunk strainers protected by stationary plates.

Figure 5 is a side view of-a, modification of my invention, illustrating the manner of protecting the eountersunk strainerse-when the tube is bored into the ground. i

Figure 6 is a side view of the same, showing the countersunlc strainers uncovered.

Similar letters of reference indicate like parts. A

i My invention relates to the construction of the lower sections of tubing to be useddfor obtaining water cheaply and readily in clay or I sandy regions without 'the expense and trouble of digging wells. And it consists in forming ceuntersunk strain'ers in the sides of the lower seetionor sections of the tubing, in protecting said countersunk strainers with hinged or stationary plates, in the combination of adjustable cone or cup-shaped strainers with the tubing, and in the combination of an interior section having countersunk strainers, with an exterior section having screw-threads formed upon it ;A the'whole being constructed and arranged as hereinafter more fully described. In the lower section or sections of the lower part of the tubing are formed holes for the ingress of the water; These holes are countersunk, as shown in the drawings, and in the countersinks thus formed are placed stra-incre A, which are secured in place by solder, or in i any other convenient and substantial manner. This construction prevents the strainers from being injured by comingv in contact with the interior cpv/A exterior tubing, with the protecting plates, or with the'ground. When the tubing is driven into the ground the strainers A are covered and protected by plates B, which are secured to the sides of the tubing by screws, and kept from covering the strainers too closely by blocks .C placedbetween said plates and the side of the tubing and heldin place by the screws-that hold the said plates. Or the strainers A may beprotected by plates D -hingednt one end to the side of the tubing, .and the other edge shutting down at the side of a stationary bar, E, securely attachedto the side of the tubing. When the hinged plates D are used, the lower section or sections in which the countersunk straincrs A are placed must be madedouble; that is to say, must consist oi' an exterior and interior tube, both of which are provided with countersunk strainers: The movement oi' the exterior and interior tubes upon each other is regulated by stop-pins F attached to the inner tube, and working in slots formed in the outer tube, as shown in gs. 1 and 3. The ends of the pins F project through the outer tube, and are inclined, so that when the inner tube is revolved to bring its strainers opposite to the strainers in the outer tube, the ends of which pins may raise or open the hinged plates D, so that the water may enter the tubes and beuaised by the pump. This construction may be used when the tubing is driven into the ground, when it is bored into the ground, or when itis placed in a hole bored by a separate auger. Gr are cone or cup-shaped straincrsv attached to a central rod, g', and placed wherever'desired between the sections that contain the countersunk strainers A and the pump. The upper ends of the mouths of the stra-iners G'are kept distended by coiled wire springs, as; shown in iig. 2; and a loop or eye is formed upon the upper end of the rod g for convenience in removing or adjusting the strainers G, as may be required. 1n figs. 5 and 6 an auger, H, is represented as being formed upon, or attached to, the lowcrend of theinterior tube, se that the tube may be made to force a passage for itself intothe ground; and the exterior tube is represented as having a screw-threml,` l, formed upon it; which screw-thread is continued downward to the auger by passing around a band placed upon, and securely attached to, the lower end of the interior tube. Upon the upper edge of this band, and upon the lower edge of the' exterior tube are formed shoulders, which take holdl of each other` in the manner of a clutch to force the auger into the ground. When the tube has been forced to the required depth, the outer tube is turned in the other direction, which raises the buter t'be and unooves the countersuuk stmners soy that the water can ow into the tube andbe raised by the pump. l v What I claim as new, and desire to secure by Letters Patent, is-

1. Protecting the countersnnk straineis A by hinged pates D, or statinary plates B, snbstantiellyas represented and described. i

2. The couibination of the cone or cup-shaped srainers G Withthe tubingsubstantilly s imeiein shown and described.

The above specifieatin of my invention signeii by lme this 6th day of November, 1866.
