SPEGIFIGA'IION forming part of Letters Patent No. 228,780, dated rJune 15, 1880.

' Application sien Maron 31,1880. (Nomen.)

lo all whom it may concern V Bc it known that I, THEODORE VON RING- HARZ, of Baltimore city, State of Maryland, have invented certain new and useful Improverments in Earth-Boring Apparatus for Artesian and other Wells; and I hcreby declare the same' to be fully, clearly, and exactly described as follows, reference being had to the accom panying drawings, in which- Figure] is a side elevation, part-ly in sec- ,A tioin'of tbe device; Fig. 2, a side elevation and top plan of the bit, and Fig. 3 asimilar view cfa Inodilied form ofthe same.

My 'invention has reference to boring apparatus for metallurgical prospecting, as Well as `for makingoil, salt, or Artesian wells; and it consists in a tubular boring-shaft provided with a laterally-apertured bit and a tubular follower or casing, adapted for use 4in connection with a forced fluid-supply, and in certain features and details 'of construction, as hereinafterfuliy set forth and claimed.

In the accompanying' drawings, A is a tubular casing for 'the well, provided at its lower end with a cutting-spur, a, and having an oven flow-pipe, D, and handle or lever B, by means of which it may be reciprocated or turned.

C` is a tubular shaft, similar to that of an ordinary diamond drill, passing freely through the casing A, and armed at its lower end with abit, c, provided with lateral grooves c', lead inginto the interior ofthe pipe C.

The bitis of a size to nearly ft within the pipe A, and is either a chisel-bit, as shown in Fig'. 2, or is provided with curved wings c", as shown in Fig. 3, the shape depending upon the nature ofthe soil in which. the boring is to be done.

The tube C is fitted with a swivel-neck, F, to which is coupled a flexible tube, f, communicating with a continuous supply force-pump, G, located in a water-supply tank, H.

A mauometer, le, is in communication with any convenient part of the pipe for delivering the water, under pressure, to the tubular shaft C. E is a lever or handle, by means of which the shaft C may be reciprocated or turned.

In operation, the boring is effected by means, of the shaft C and bit c, the casing A being made to follow the bit as it descends. Meanwhile a current of water is driven by means of the pump down theshaft C, and rises around it after finding egress through the grooves c of the bit. Ihe material disintegrated bythe bit is thus carried up and is delivered with the water at the spout D. Here the water is received into subsiding-tanlcs, w'liere the earthy and mineral matter subsides and may be rcmoved for examination or analysis. The clear water may be returned to 4the tank lil in case 6o the supply is inadequate.

' As long` as the drill is cutting` through earthy or mineral matter the manometer c' indicates a constant pressure; but the instant a stratum of water, brine, or oil is struck by the drill the 6 5 factis indicated by the behavior of the manometer. An Artesiau stratum of liquid- 17. c., one under pressure-makes itself apparent in a rise of the mercurial column, while one not under pressure is noted by afall. Thus all 7o dan ger of perforating a liquid stratum without notice is avoided.

As the casing' and shaft' descend new sec tions are jointed 'to them in the usual way.

I am aware that it is not broadly1 new to re- 75 move the earth upward about a tubular drill by means of a current. of Water pressing either down the vtube and up varound it, or down around it and up the tube, and such I do not claim.

What I claim. is-

l. In an earth-boring apparatus, a tubular boring-shaft carrying an apertured bit and inclosed in a casing descending thereafter, and a forced liquid-supply in communication with the tubular boring-shaft, as set forth.

2. The combination, in an earth-boring apparatus, of a casing; having a terminalcutting bit or spur, an inclosed .tubular boring-shaft having a laterally-apertured bit, and a forced 9o liquid-supply in communication with the boring-shaft. .Y

3. The combination, with a liquid-forcing apparatus and a tubular boring apparatumof a manometer, as and for tbc purpose set forth.

4.1m combination` with the liquid-ibrcing apparatus and inanometer, the casing A and tubular boring-shafthaving apertured bit, as described.
