' Specification forming part of Letters Patent No. 17,

December 20, 1%64.

To all' whom it may concern:

Be it known that we, HENRY HANNEN and JOHN PARKER, of Philadelphia, Pennsyl-l vania, are' the owners of certain Letters Patent for Improvement in Apparatus for Boring Artesiah Wells, granted to M. W. BOLLES (assignee of JEssE N. BoLLEs) on the 14th day ot' April, A. I). 1857; tllat we deem the said patent inoperative and invalid by reason of adefcctive specification, and that the following is a full, clear, and exact description of thesaid invention. The inveuion ot' the said BOLLES consists, tirst, in combining with a rock drillv or cutter certain tubular rods through which the detritus is caused to pass upward and tobe discharged at the point desired; secondly, in a. valve or valves arranged within thc said tubular drillrods, for the purpose of raising the detritus; thirdly, in a drill or cutter coustructed snhstantiail after.

In order to enable others skilled in the art to make and use this invention, we will now proceed to describe its construction and operation. I 0n reference to the accom pauyin g drawings, which form apart of this specification, Figure 1 is a section of a portion of a tubular drill-rod with the drill attached; Fig. 2, sections of the tubes composing the remainder of the drill-rod Fig. 3, a section on the line 1 2, Fig. 1; Fig. 4, a transverse section. on the line 3 4, Fig. 1; Fig. 5, an exterior view ot' the drill; Fig. 6, au inverted plan view ot' the Balve, and Fig. 7 a perspective view of the drill inverted.

Similar letters rch-r to similar parts throughl out the several views.

A is a steel cutter orv drill, which consists 0f the two port-ions a u' ot' a cylinder, sharpened attheir ends so as to form two curved cutting-edges, the two parts being united by a cross-piece, b, the edge of which in also sharpened and brought to a point, m, the latter projecting to the extent of halt' an inch, or

thereabout, beyond the edges of the portions a a'. The cross-piece b of thedrill should be about two inches wide and three-fourths of an inch thick, and near the cutting-edge it is y as described herein` 064, dntedApril 1 4, H57; Reissue No. L83?, dated as required, the shank ig also three-fourths of an i beveled more or less, f c of the ,drill beh the bore of the tubular drill-stock B, Fig. 1, which is two inches iu diameter, theie being. consequently, a space between the inside of the drilLstock and the shank b, on each side of the latter, as best shown in Fig. 4. ,The drill-stock B, to which the drill is secured in any suitable manner, is lnade in part of extraheavy wroughtiron gas-pipc, three or four feet long, and in part of cast-ironl shrunk on the gaspipe for about twenty inches, at the ltwer end, two of the sides being rounded to ccrrespond with the rounded'portious a a' ltiatteued and lparallel with each other, as shown in ',"i g. 4'. -Upon the inside of the upper responding with a similar thread on the lower end of a. wrought-iron gas-pipe, C, in the uppzr end of which is a coupling, D, containing a brass valveseat, e, and to the latter is hinged an ordinary valve-, f.A

0n the lower end of the tube E is a thread upper'end of the tube is a reducing-coupling, D'., with internal threads adapted to those on the end of the tube E. Y

The tubes F, G, and 1I, which constitute the main drillingrods, are made of wroughtinch in diameter, and a-re connected together ,by wrouglrtiron sockets or couplings D", Iabout i'onr inches long thick, and tapped slightly tapering, so as to bring the rods 'nearly together. The screwjoints should bekept perfectly tight, when the machine is in operation, by turning the rods in the direction'of the screws. Near the upper end of the tube H is au opening, i', for apurpose described hereinafter.

' weil as the tubes, should bc placed in a l so that the threads may be )xzrfectly cnt The screws should be slightly tapering, so that the tubes, where they are coupled togather, may herself-tightening ou being turned round in the proper direction.

athc,

inch thick, and ot' such a width as to tit into of the cutter, while `the other tw sides are end of the drill-stock is cut a deep thread coradapted to that in the coupling l), and on the iron gas-pipe, extra heavy, oneV und one-halt i one l'ourth ot' au inch The tubes may be from .tive to fourteen feet in length, and the sockets or couplings,las

I inches at each stroke,

. The tubes should not beallowed to butt to '5,ether,

the joints be so that when the various parts are connected they will form a pe: fectly straight, continuons, nollow drill'rod. v

Although the apparatus may be operated by mechanisrnof various kinds, we prefer at# taching it to the roek-drilling machine for which apatentwas gr anted to Bulles and Mcf Knight, May 1,. 1819, which raises the rod'six und about sixtytimes per minute.

l AWhile the rock is nanny broken by uw cutting-edge of the portion b of the drill, the

cutting-edges of the portions ara serve to make the opening perfectly vround and even. After the machine is set in .motion the de tritus and water in the'well gradually till the hollow` tubes-and are raised by the action of thelatter and the valve f, until discharged through the opening i, or through openings made in anyot the tubes at any desired point.

It will be seen that by the use of the hollow drill-rods the detritnsis constantly raised from the well during the 'operation of the drill, and thatvthe labor and delay heretofore necessarily incurred in withdrawing the tubes in order to remove the detritus is thus avoided.

By examining theA character of the detritus discharged, the attendant `is enabled to ascertain whetl erth'e drill requires ysharpen'-` intr. without withdrawing the latter from the n well. 4

Should it beJound necessary, th'ewalve'f may placed directly above the cutter A,or

ingl made with precision, y

.into the opening of `names to this specilicntion beforeI term-sub- -iu any other `position desired, and, 'it deemed necessary, nn additional number of valves may be used.

By extending the sides of the portions a a.

of the cutter beyond those ot' the central crossypiece, b, `a space or chamber is formed at each directs the detritus-` side ot the latter which the tubular drillstock.

Although certain dimensions havel been given for the several parts of the apparatus, it will be evident that these dimensions may be varied to suit the size of the well to be.bored.

We claim asV the invention ofthe said J. N. BoLLEs and desire to secure by Letters Patent- 1. The'combimtlonbf a drill -or cutter, A, with tubular rods, through whichthe detritus is causedtopass upward, and to be discharged at the point desired, substantially as speci lied.

2. One or more valves, j: arranged within the tubular drill rods of a well-boring machine, substantially as and for the pnrpnse set forth.

3. The drill or cutter A, composed ot' the portions a a' and jcrosspiece b, constructed and arranged substantially as and for the purpose set forth. f

In testimony whereof we have signed our :crib ngvwtnesses. l,
