SPECIFICATION formingpart of Letters Patent No.631f dated August 22, 1899.

Application filed April 28, 1898- To all whont it nwry concern.-

Be it known that I, ALBERT FAUCK, a citizen of the United States, residing at Marcinkowice, in the Province of Galicia and Empire of Austria-Hungary, have invented new and useful Improvements in Rigs for Boring 'Wells, of which the following is a specifica-' tion.

My invention more especially relates to that method of boring wells according to which an annular section of the rock is operated upon and cut away, so that a core is formed in the center of the hole. In order to remove the said core, it was necessary hitherto from time to time to withdraw the rod and bit wherein the sections of the core were retained. It is obvious that this alternate withdrawing and lowering out of the rod and bit consumed much time and labor.

The object of this invention is to overcome these difficulties and to provide means for removing the core without withdrawing the rod and bit.

According to my invention the tubular bit and rod are very rapidly reciprocat'ed in strokes of little throw, the tubing of the well is tightly closed at top, and a stream of .water is forced down through the said tubing.

The water ascending through the tubular bit and rods carries along the sections of the core, which are prevented from clogging by the continuous shake of the bit and rods. I impart to the drill its rapid reciprocating IDO- tion by suspending it from a rope, the other end of which is secured to the derrick and which is run around a pulley looselymounted upon the crank-pin of a revolving crankshaft or upon an eccentric-shaft journaled in the derrick below the point where the end of the rope is fastened. The tubular bit has reaming-cutters pivoted to its lateral sides, and its radial cutting edges are at two diametrically opposite portions of greaterlength than the rest, whereby jamming in of the drill is prevented.

In order to make my invention fully understood, I shall hereinafter fnlly describe the same with reference to the accompanying three sheets of drawings, in which Figure 1 is a sectional elevation on line 1 '1, Fig. 2, of my improved boring-rig; Fig. 2,

a sectional elevation on line 2 2, Fig. 1; Fig.

Serial No. 678,683. W0 model.)

3, a sectional elevation, drawn to a larger scale, of the lower extremity of the hole being bored, the bit, the reamers, the tubing,

and the core. Fig. 4 is a horizontal section on line 4 4, Fig. 3, and Fig. 5 is an end View of the bit.

Referring to Figs. 1 and 2 of the drawings, a is the wooden derrick, built up in the wellknown manner of sleepers, a base-frame, standards, struts, and a top frame. The driving-shaft b, to which motion is imparted from any suitable motor by means of the rope-pulley b, transmits the motionjby means of the rope-pulleys Z7 and c and the.drivingrope d to the crank-shaft c, which may be replaced by an eccentric-shaft. When it is required to revolve this latter more rapidly, the driving-rope d is passed around the pulleys b and c of the shafts b and 0, respectively, and the pulley b is geared with the motor.

The rope d, from which the drill is suspended, has its end fastened to a drumf, the shaft of which is journaled in bearings secured to struts of the derrick a. The said shaft of the drum f-also carries a worm-wheel f, in gear with the worm f to the shaftf of which is secured a hand-wheel f It will be readily understood that by turning the hand-wheel f the rope d, wound around the .drumf, may be lowered out or shortened in. From the drum f the rope d runs over a guide-pulley I, the pivot of which rests upon the cross-beams a of the derrick, and from this pulley downward over a pulley g, which is loosely mounted upon the crank-pin of the crank-shaft 0. Then the rope is passed upward to be slung around a guide-pulley h, mounted upon the top frame of the derrick in such a position as to bring the downwardly-extending portion of the rope d into the axis of the well.

By means of a stirrup i the rope d is connected with the tubular drill-rode, which en-- ters the tubingj of the well through astufiing-boxj made integral with the cap j that is screwed upon the top section of the tubing j in order to tightly close it. The said cap j is provided with a branch j 3 to be coupled with a hose Z, through which a stream'of water under pressure is forced into the tubing j. The stream of water flowing downwardin the tubing passes at the bottom of the well into the tubular bit 7t 70 k hereinafter more fully described, and carrying along the loose sections of the core it rises within the bit and tubular rod i, the top end of which carries a vessel m, intended to receive the sections of the core. The hose Z carries ott the water.

The tubular bitis composed of threepartsviz., the bit proper, 7a, the reamer-carrier 7t, and the connecting-piece 70 to be screwed into the tubular rod The bit proper, 7c, is provided with radial cutting edges 91 and 12, formed on its face, the diametrically opposite edges n being longer than the edges n in order to prevent jamming of the bit in a certain measure, as thenumber of diametrically opposite portions subject to jamming is thereby considerably reduced. The reamer-carrier 70 has reaming-blades o pivoted in suitable recesses of its sides. The headed pins 0 bear against shoulders 0 of the naves of the blades 0, and under the action of coiled springs o abutting against the screw-plugs o, by which the bores 0 containing the pins o, are closed, the said pins cause the blades 0 to swing outward. \Vhen the drill is withdrawn from the well, they fold against the reamer-carrier 7; as soon as they meet the bottom edge of the tubing '0.

It will be readily understood that the pulley g, mounted 011 the crank-pin of the 0011- I tinuously-revolving crank-shaft c and acting upon a bight of the rope d, from which the l drill is suspended, must impart to the latter When the rope a rapid to-and-fro motion.

d is run over the guide-pulley I, the portions 3 of the rope on either side of the pulley g are parallel, and consequently the throw of the 1 drill must be double the throw of the crank. Q In order to afford possibility for reducing the I throw of the drill, there are yet three other guide-pulleys II, III, and IV, suitably mounted to the derrick in such positions as admit of directions more or less deviating from the 3 parallel one being given to the portion of rope between the drumfand pulley g. The different directions the rope may be given are indicated by dotted lines in Fig. 1, and itis obvious that with the guide-pulley IV the shortest throw will be obtained, and with the pulleys III and II gradually longer throws. Having fully described myinvention, What I claim, and desire to secure by Letters Pat;- ent, isi In a well-boring rig, the combination with 1 a derrick, a revolving crank-shaft journaled in the same, a pulley loosely mounted to the crank-pin, a guide-pulley mounted upon the top of the derrick, and a rope running from a fixed point of the derrick above the crankshaft around the crank-pin pulley and guidepulley of a tubular drill-rod, a tubular bit having on its circular cutting-face radial cutting edges, which are outwardly extended on two diametrically opposite portions of the said cutting-face, reaming-blades pivoted to I the bit, a tubing closed at its top and means for forcing water into the said tubing, substantially as and for the purpose set forth.

In witness whereof I have signed this specification in presence of two witnesses.

ALBERT FAUCK.
