APPARATUS FOR BOFiING ARTESIAN WELLS.

SPECIFICATION forming part of Letters Patent No. 492,536, dated February 28, 1893.

Application filed April 6. 1892. Serial No. 428,099. (No model.)

To all whom it may concern.-

Be it known that I, FRANK O. BROWN, a citiof the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain Improvements in Apparatus for Boring W'ells, of'which the following is a specication.

My invention relates to certain improvements in apparatus for boring wells, and the object of my invention is to provide an apparatus for this purpose which shall be simple in its operation and readily adjustable for penetrating substances of various resistances whereby the breaking of the drill head will, to a great extent, be prevented, all as will be more particularly described hereinafter.

In order that my improvements may be the better understood I have illustrated in the accompanying drawings an apparatusembodying my invention, in `which drawings- Figure 1 is a plan view and Fig. 2 is a side elevation of the apparatus, drawn to a small scale. Fig. 3 is a view similar to Fig. 2 showing the use of the clamps for rotating the tube without the ropes shown in Fig. 2, and Fig. 4. isa detail view.

In the Views, D represents a heavy bed plate provided with an annular raised facing D on its upper side, which facing is grooved and adapted to receive balls P, as seen in Fig. 2, to reduce friction. The bed plate is set upon the ground over the spot where it is desired to operate and has a centrally arranged openin g through itfor the passage of the tube or casing to which the head is secured.

- B is a bevel gear wheel having a groove in its lower side corresponding with and fttin g over the balls P in the groove in facing D', as seen in Fig. 2, and h is a bevel pinion mounted in bearings (not shown) at one side of the apparatus and meshing with gear wheel B, whereby said wheel may be rotated, said pinion being driven from any source of power, as a whin for instance, also not shown.

A is an annular flat table mounted loosely on a shoulder on wheel B, and having its edge projecting beyond the edge of said wheel and engaging jaws f on brackets F secured to the bed plate D, one of said jaws on each bracket lying above and the other below said table whereby said table when rotated, moves between the same, as will be understood by inspection of Fig. 2. Said jaws f are provided with perforations and the edges of the table A are likewise correspondingly perforated whereby said table may be locked fast to the bed plate by means of pins Z, inserted through said perforations as shown.

On the boss of wheel B is formed a second gear B', projecting above the upper surface of the tableAand on the upper surface of the table A and on diametrically opposite sides thereof, are mounted upright shafts or arbors N, united by a tie bar M at theirtops, on which shafts are mounted toothed gear wheels C, 0,the bosses of which are in the nature of drums C', C.

E, F., are toothed gear wheels suitably mounted on the upper surface of the table and adapted to be thrown into and out of engagement with therespective gears B and C, C, at will for purposes to be hereinafter set forth.

H is a .frame of inverted V-shape, mounted on the table A and bearing at its apexa hook lo, having a screw threaded shank passing through a collar h on said frame and engaging a hand wheel K, thereabove, whereby the height of said hook above table A may be regulated.

J is a block mounted on said hook and L is a wire rope or chain, passing over the sheave of said block and down on each side of the same, taking under sheaves I, I, secured on arms projecting upward from table A. Thence said rope L passes, in opposite directions to and around the respective drums C on each side of the table.

O represents the tube or casing to which the drill head is secured and to which it is desired to impart a downward as well as rotary movement, and this tube passes through co-inciding openings formed in wheel B and bed plate D, which openings should be of sufficient size or diameter to admit of the passage therethrough ofthe couplings employed for connecting the several pipe sections. j

From the respective drums C', C', the rope L passes, in opposite directions, about the tube O, as seen in Fig. 2, and back again to the drum C on the opposite side of said table.

As shown, three strandsfof said rope are em- IOO ' will be understood.

a l agate@ pioyed on each side of the apparatus but the number of strands is vunimportant and may be varied according to circumstances, depending on the substance to be operated on, and consequent resistance tending to cause slipping of the rope on said tube O.

The method of operating the apparatus is asfolloWs:-The apparatus having been set in place for operation, the tube O, with the drill head is secured in place and the ropes passed around the same and the drums and pulleys. The slack is then taken upA by means of the hand wheel and screw on hook 7c after which rotary motion is imparted to the gears rb, B,- and table A, said table being locked fast to said gear wheel B by means of a bolt G, engaging eorrespondngsockets.in the respect-l ive parts. The .rotary motion of the apparatus is continued until the lowest turn ofi the rope -L about tube O has reached thelevvel. of the gears C, when Vthe latch G is thrown out of engagement with gear B and the pin? Z is inserted through `the openings in jaws and table A. The gears Eare :then throwni into engagement with gears B and C when the ltable A will remain stationaryand rotaryf motion will be imparted to drums C .and` through the rope thereabout totube O, the'` Wire rope L in this case however, rising on? the 4tube at each revolution of the same, as i In the operation of thef apparatus, the rope rises on tube O at each; revolution, the amount .of its diameter, lessy the distance the pipe has been lforced into the earth, and in operating in ordinary soft material these two items will be about equal and as long as this condition remains, the op-` eration `as last described `may be vcontinued.` But should the tube not enter Vthe earth suf` ciently fast, from the resistance offeredthere-' toor any cause, the rope ascends on ,the pipe and drums to near vthe top of the latter whenE the `table A will be again loosened from` brackets F, gears E thrown out of engage. ment as shown in dotted lines in Fig. 1, said gears being eccentrically journaled in the. table vA in any Well known manner and bolt G dropped into the socket in gearwheel B;

when the first described method will ybe resumed until theprope has traveled down again z 'the necessary slack being given and taken up as the rope travels up and down by means of hand wheel K. Slack should also be given to admit the passage of the couplings through the apparatus.

In order to provide against back rotation vof tube O,when the apparatus is stopped froml any cause, I prefer to provide the block J with a chock or wedge-shaped block A as seen in s Fig. 2, which can be placed between the top of the block J and the rope and thus stop the passage of the rope through the block in the well known manner.

In operating upon very hard substances,

there is a constant tendency for the rope L to slip and to prevent this, as Well as to remove undue strain therefrom, I provide a clamp as seen in Fig. 4, which consists of two halves or sections c, having bolts b headed on one side thereof and passing through the ends thereof to the ends of which bolts are coupled slotted cam levers d', c', as clearly seen in said View. The sections c, have arms c', which, when the device is in place about the tube O, project laterally and engage with the 'drums C', C', on each side of the apparatus so that when the sections are clamped fast to the tube or casing said tube will be rotated positively from table A, without recourse to rope L in driving.

I do not Wish to be understood as limiting myself to the precise construction and arrangement of the various parts shown herein for carrying my invention into practice, as it is evident that many alterations maybe made therein without material departurefroln the principles thereof.
