THOMAS J. HATHAVVAY, OF MONTEVALLO, MISSOURI.

WELL-DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 289,257, dated November 27, 1883.

Application filed September 20, 1883. (Modem 7 To all whom it may concern.-

Be it known that I, THoMAs J. HATHAWAY, of Montevallo, in the county of Vernon and State of Missouri, have invented a new and Improved Well-Drilling Machine, of which the following is a full, clear, and exact description.

The object of the invention is to improve well-drilling machines, as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of my improved drillingmachine. Fig. 2is a horizontal section. Fig. 3 is a side elevation of the drill. Fig. 4. is an endelevation of the drill. Figs. 5, 6, 7, and 8 are details. I

I arrange a stationary toothed rim, a, on the bed-frame b of a wagon, and fit a turntable, 0, around said rim for a pivot, and on rollers a of bed-frame b for a support, to be turned by a team hitched to the sweep d, and traveling around the wagon. The turn-table carries the tower or derrick e, from the top of which the drill-ropef is suspended by a pulley, g, over which the drill-rope passes from the drill-rope beam h, fitted on journals having bearings in the uprights 1, supported on the frame-piece j and by a couple of the tower-uprights e. The pulley 9, over which the drill-rope passes, is mounted in the vertically reciprocating gate is, fixed in guideways Z at the topof the tower, and connected by rod m with a cranlvpin, 0, on the drum 1), fitted loosely on the drivingshaft q, and connected to said shaft by the internally-toothed flange .9 of the drum and the spring-pawl tof the hub a, keyed to the shaft (1 inside the drum, which arrangement enables the drill to be worked when the shaft q is turned forward, and allows the drill to rest when the said shaft is turned backward. This mode of connecting the drum 1) to the hub a is also employed in order that the connecting-rod on will fall instantly after passing the upper center of the crank-pin, to allow the drill to strike properly, the fall taking place when the thrust of the weight of the drill, rope, rod m, and the pulley and its frame passes from the rising to turn-table is revolved by the team.

the descending side of the drum and in the direction the pawl 25 drives. The shaft q also carries a loose bevel-wheel, e, that rests when the shaft q turns forward to work the drill, and is engaged by its toothed face 3 and the spring-pawl w of hub 00 when the shaft q turns backward, and then turns the beam h by the wheels z, a, and Z) to raise the drill out of the well when required, the team being then driven the reverse way around the machinethat is to say, to the left hand. The shaft qis arranged in suitable bearing-supports, c and d, on the turn-table, and has atoothed pinion, e, that gears with the stationary toothed rim a, and causes the shaftq to revolve when the A stoplatch, f, is arranged on oneof the uprights i in connection with toothed wheel I), to prevent the drill-rope from unwinding from the beam h faster than required, and a lever, having a stop-latch, h, is fitted on the journal of the rope-beam h in relation to wheel b,

whereby the turning of the rope-beam to let out the drill-rope from time to time as the drill works down may be controlled, to prevent the overrunning of the beam by the weight of the rope. These latches f and h have the usual trip-handles, j, for disconnecting them from the wheel, and springs or other means to keep them in connection with the wheel.

When the drill is to be let down into the well from the surface of the ground, or any other considerable distance, it is to be done by turning the machine forward or allowing it tobe turned forward by the weight of the drill, the wheel 1) being keyed fast to the shaft, and the spring-pawl t of the crank-pin hub p being secured in any way to prevent it from engaging ratchet-rim s at that time, and the stoplatches f and It being disconnected from wheel Z).

To prevent the overrunning of the machine by the weight of the drill when thus lowering it, I have attached a smaller sweep or lever, is, to the turn-table in advance of the sweep (Z, to which the horses are hitched, to which lever is the holdback-gear of the harness may pivot n on one of the uprights c, said arm, having the-pulley 0, hanging from it over the well when the said arm is properly adjusted, and being temporarily secured in position by a notched keeper, p, pivoted to another of th uprights e, and crossing and dropping onto arm m suitably for holding it. The sandpump rope runs from the pulley 0 to the windlass q, whereon it is wound and unwound to operate the pump. \Vhen the pump is to be removed, the keeper p is detached from the arm m, and the said arm is swung back out of the way of the drill-rope.

My improvement of the drill consists of two parts, each having a radial bit, u, and a circumferential bit, 12, and being placed side by side along the center line, to, so that the two bits. a, substantially form the ordinary plain drill-bit, the width of which corresponds to the diameter of the well to be drilled, and the bits 12 form curved lips to the outer corners of the bit a, which out along the circumference of the hole and materially facilitate the work. The two parts each have a shank, ac, which together are suitably shaped to form a dovetail, and are fitted to the dovetailshaped notch 3 in the lower end of the drillstock .2, where they are secured by the band a which drops on the taper shank of the stock to the required position for keeping them in place, and is raised above said shanks when the drill-bits are to be taken out At the upper edge of the band a", which fastens the bits, there is to be a hole for a key, If, to fasten the band, one-half of said hole being formed in the shank of each bit, which secures the bits firmly by keeping the band in position.-

In this improved drilling-machine the hand for turning the drill in the hole by the rope will be dispensed with, because the drill and the rope are turned by the rotation of the turn-table for working the drill, the length of the stroke of the drill will be the same whether the team goes fast or slow, and the saving in time and labor by the arrangement of the drill to be worked on the wagon-bed without unloading or taking apart will effect considerable economy in the working of welldrilling machines. The machine is also applicable for driving well-boring angers by taking ofi' the connecting-rod m and arranging a cross-bar, b having a socket, c, for the shank of the auger across the center of the turntable, so that the rotation of the turntable by the team will turn the auger. The sweeps d and k are pivoted to the turn-table at d and 6 to enable them to be swung up to the tower and be secured thereto by cords when the machine is to be transported along the road.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a wagon-bed frame having the rollers a, of a stationary toothed rim, a, a turn-table, 0, pivoted on said rim, a tower, 6, arranged on said table, and a device, (I, to which horses may be hitched, as shown and described.

2. The combination, with the tower e, of the drill-rope f, the pulley g, the journaled beam h, the uprights t, the frame j, the reciprocating gate k, arranged in guides Z, the rod m, the drum 1), having crank-pin 0 fitted loosely on drive-shaft q, and provided with internally-toothed flange s, and the hub a, carrying spring-pawl t, whereby the drill may be operated, as described.

3. The drill-rope f, extended from the ropebeam it over the vertically-reciprocating pulley 9, connected to and operated by the crankshaft q, and being connected thereto by an escapement device, enabling the drill to fall when the crank-pin has passed the upper center, substantially as described.

4. The combination, in a well-drilling machine, of the drill-rope f, beam h, pulley g, sliding gate 7c, connecting-rod m, and the driving crank-shaft q, substantially as described. v

5. The drill-rope beam h, geared with the driving-shaft g, by the ratchet-faced wheel 1), pawl w, collar w, and the intermediate gears z, a, and b, the ratchet and pawl being arranged to disconnect when the shaft q turns forward to work the drill, and to connect and raise the drill when the driving-shaft is turned backward, substantially as described.

6. The combination of the stop-latch f, lever g, and stop-latch h, with the toothed wheel I) on the rope-beam 71, substantially as described.

7. The combination of the shifting sandpump derrick m and p with the drill-rope tower e, and the sand-pump rope Z, substantially as described.

8. The improvement in well-drills, consisting of the drill made in two parts, t, each having a radial bit, a, and a circumferential bit, '0, said parts being placed side by side, and secured in the drill-stock together, substantially as described.

9. The drill consisting of two parts, t, each having a taper shank, 00, forming together a dovetail shape, and being secured in the dovetail notch y/ of the stock 2 by the band a", substantially as described.
