lIMPROVEMENT IN TUBE-WELLS.

Specification forming part of Letters Patent No. 92,569, dated July 13, 1869 reissue No. 4,604, dated October 24, 1871.

To all whom it may concern:

Be it known that I, SoLoMoN L. BIGNALL, of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement' in 'lube-lVclls, ot' which the following is a speeiication: Y

The nature of the present invention consists: First, in the novel construction of the device for removingl the earth as theI tube is being put down, and so packing-it as to make a hole somewhat larger than the tube, thereby allowing the latter to be sunk to a great depth byhand-power in any soil where there are no stones. Secondly, in t'orln'ing the wire-cloth used for screening purposes o'ver rings which are so bent as to iit the periphery of the pipe to which they are soldered for protecting the wire-cloth without weakening the tubing, as the whole is hereinafter described and shown.

Figure l is a perspective view of myimproved well-point; Fig. 2, a centra-l section of the same; Fig. 3, a perspective view of one wing of the sinkingand' packing device removed. from the point; Fig. 4., the ring` to which the wire-cloth is attached; Fig. 5, the wire-cloth before it is formed over the ring; Fig. 6, a view ofthe wirecloth as it is formed over the ring preparatory to being soldered to the tube; Fig. 7, atop view of oneI of the wings.

A represents lthe lower end of an ordinary pipe used in sinking tube-wells, and J J show the holes through which the water passes into it. G represents a inet-al screw-point, which is placed inside of the tube A and fastened there by means of a'bolt or otherwise, as most convenient. It is not necessary, however, for sinking wells in sandy soil, that th'e point G should have a screw-thread, a plain conical point being suiiicient to guide the tube. Wings 0,'-made of steel or iron, according to the service required, are bolted fast to the point G, between the screw-threads and a shoulder, K, the opposite sides of the point being tlattened or cut away. for this purpose. rlhese wings extend out a short distance beyond the periphery of the tube A, and are provided with shovelshaped lips E on their lower edge for loosening the soil as the tube is being sunk, and with 'ilaznges D on their outer ends for the purpose 0f so packing the earth surrounding the hole as it is -loosened asl to form a wall sufficiently compact to relieve the tube A from any considerable friction, which would otherwise result if the earth were permitted to fall back against it.l

structed a tube-well may be sunk to a much greati er depth thai when driving is wholly relied on, and atmuch .ess cost than when the earth is carried to the surface with an auger, saving at the saine time the expense of a driving or boringmachine, and also the trouble of moving one from place to place. The holes J J are covered with ire-cloth, as follows: A series of rin gs, M,Fg.4, corresponding to the number of holes J through the tube A, is so covered with circular pieces of wire-cloth I as to project above the area of the inclosed parts through which the water passes. This is generally done with dies made for the purpose, but the edges of the circular piece I may be quickly formed over the wings by hand, care being taken, however, not to cut the pieces of wire-cloth so large as to more than overlap the rings. lhe rings, with t-he wire-cloth on,'are then so formed by a die orotherwise as to closely iitthe1 eriphery ofthe tube,(surroundingthe holes` J J, &e.,) to which they are fastened with solder to the outside of tube; or the wire-cloth can be fastened to the tube by solder alone if the solder forms a ring around the wire-cloth, so that the latter is protected when the point is being sunk. By means of this arrangement the wire-clothis held much more iirmly in place than whensiinply secured by the solder alone, while at the' same time the additional cost of rings is saved by solder. The rings project-ing beyond the wirelcloth protect thc latter from wear or displacement when the well is being sunk. rllhe arrangement for protecting the wire-cloth and holding it in place is much more simple than couiitersinlein g the wire below the periphery ofthe pipe-tube,

inasmuch as no drilling is required, while at the saine time the tube is' not weakened by the counter-sinks. This latter consideration is an -.important o ne, for in order to procure the proper guantity of Water :i large number of holes have to .be

made in the tube, and if the holes have their margins countersunk to receive the Wire-cloth the tube is very much weakened, so much so as to buckle when being put down.

The operation is very simple, requiring only that the tube A have e length of pipe screwed fest to it, end turned into the earth by ordinary T-couplngs in the usuel manner or other Ineens new usedfor like purpose, other lengths of pipe being fastened to the preceding ones until Wet-er is reached. If the screens fill up the Whole tubing een be lifted ont of the earth where tle Well is of moderate depth; but if it is verf,Tv deep the tubing may have to be rotated When being hoisted out.

ery of the tube,to which they ere soldered, as set forth.

3. The Wire-cloth I, secured to the tubeA by a. ring of solder, with the wire ring, as set forth.
