evalueert-PIPE WELL.

SPECIFICATIONformng part of Letters Patent No. 255,664, dated March 28, 1882. applicati@ filed september 21, ism. (No motten others skilled in the art to which it appertainsl to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, `which form a part of this specification.

My invention is un improvement inf/,boring and curbing wells.

It consists primarily iu the method of forming wells by using an augerof large size to form a shaft to receive several joints of curbing, then undermining said curbing by boring with asmaller auger to settlethe same until aproper depth i's reached and suflicientwater is found', additional sections of curbing being added at the top as the work progresses, after .which the well is capped, all of which will be hereinafter fully set forth. y

It consists, secondly, in the formation of well-curbing in sections, jointed together with rabbet-joints, which form "cone-frustums, said 3c joints being completed by the introduction of cement as the several sections are placed uponn their correspondents.

In my drawings, Figurel is a sectional view of a well, showing the curbing partly in elevation. Fig. 2 is an elevation of a small auger used in undermining the curbing. Fig. 3vis an elevation of au auger used for forming the primary opening.

Similar reference-letters indicate like parts in all of the iigures.

Referring to drawings, A are the ordinary sectionsof the well-curbing, and A the lower perforated section of the same. These sections, when in place, set one upon another, as shown. i

B is the rabbetjoiut formed upon'the upper end ofthe sections, adapted to receive vthe lower end of another joint correspondingly the curbing willbe as one piece, the peculiar form of the joints being promotive of this end. In forming a well by my method I use first 4an auger of large size of the usual construction, and sink the same until a depth is obtained sufficient to receive a few of the lengths of the curbing. rIhe earth is lifted from time to time as the auger is driven, and when the said large au ger is dispensed with the sections, one by one, are lowered-the perforated one, A', tirst--successivel y until they reach the surface of the ground. I now introduce an auger having'a smaller diameter into the space within the curbing so sunk, and drive the same to undermine and settle the curb by gravity. Additional sections are supplied as the under ones sink until a suitable amount of water is gained. Should there be at the bottom of the well a qujcksand or any substance that might be drawn by theoperation of pumping, I introduce a perforated conical bottom, (Lwhich,v

on account of its formation, settles itself into the soft material at the base of the weil and prevents said material from rising. These bottoms I form of thesame material as the curb. ing, preferably hydraulic cement, and the perforations may be of a size to suit conditions. When the sections forming the Well-curbing are in place I cap them with a top piece, D, provided with an annular groove on the under side to fitV snugly over the rabbet-joint of the uppermost section, the joint being perfected by the use of Water-lime, as previously mentioned. The top piece, D,.is pierced with a hole to receive the pump.

By my method of forming a well I avoid the troubleand expense commonly incurred by reason of caving, and -by the use of the joints shownand Vdescribed with a lling or packing oftcement I keep out. of the well proper all surface-water. f

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- A Y l. The herein-described method of forming a well, which consists in first boring with an auger into the y.ground a given depth to form an opening, then inserting, joint by joint, sections of curbing, of the form described, and

' ter-lime, so that when finished and in placev thereafter sinking the sections so inserted by with the cement liing or packing for said .boring with a smallr auger and removing joints, as and for the purpose specitied. the earth beneath an adding joints from the mouth of the well, as and for the purpose seb GEORGE D' PETTINGILL' 5 forth.
