The construc- tion of a well, spoken of in the specification as the invention made, and which it must be presumed was intended to be secured, is, thus, not merely the displacement of the earth by driving down the instru- ment or the tube, but is, in addition, having the air-tight tube in the earth with the earth packed around it, and a process arranged, by the meehanical aid of a pump, attached by an air-tight connection to the tube, for causing the water to enter the perforations at the lower end of the tube and issue from the upper end of the tube. What particular forces are in operation to produee this process of obtaining water, when the well is not a flowing well, is of no impor- tance. The specification need not explain, The meehanical means are fully explained which resuit in the obtaining of the water, from the commencement of the driving. The process of obtaining the water comprehends all the ste,ps which form part of that process, as they resuit from or attend the meehanical means set forth. The pro- cess consists in having an air-tight tube with the earth tightly packed around it, resulting from compacting the earth by displacing it by driving a rod or the tube, and having a pump attached at the top of the tube by an air-tight connection, and, by the operation of the pump, obtaining a supply of water at the top. In describing how the invention is made and used, so as to enable others to make and use it, the description inoludes driving the rod, putting in the air- tight tube, and having the pump, and obtaining a continuons supply of water. The invention being thus defined in the specification, the claim is to be construed as broadly as the invention, unless neces- sarily restricted by the langaage used in the claim. The claim is : �" The process of constructing wells by driving or forcing an instrument into the ground until it is projected into the water, witliout removing the earth upward, as it is in boring, substantially as described." �Where the well is a flowing well, the water will flow as soon as the hole is made, and to make the hole by driving and displacement, and insert the tube and have the water flow, develops the process. Where the well is not a flowing well, the pump, in addition, is neces- sary, and the use of the pump in the well so made is a use of the process. Driving or forcing an instrument into the ground until it ia projected into the water, without removing the earth upward aa it is in boring, is an essential element in the process, in either case ; and, ��� �
