PORTABLE DRILLING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 441,540, dated November 25, 1890.

Application filed March 13, 1889.

To all whom it may cmwernr Be it known that I, JOHN G. DOWNIE, a

citizen of the United States, residing at Bea- I ver Falls, in the county of Beaver and State of Pennsylvania, have invented a new and useful Improvement in Portable Drilling-Machines, of which thefollowingis aspecification. Hy invention relates to an improvementin portable drilling and pipe-driving machines to for making water-wells, oil-wells, and prospecting for minerals; and it consists in the peculiar construction and combination of parts, that will be more fully set forth hereinafter, and particularly pointed out in the claims.

In portable drilling-machines as heretofore constructed the shaft carrying the rope-reel has usually been arranged ina plane at right angles to the walking-beam, which latter has usually been placed longitudinally with relation to the frame. The result has been that ithas been impossible to use a reel of sufficient length for deep wells, sincea reel about four feet long is as long as can be mounted to work wellon a portable machine, placing it crosswise in the frame. By my present invention I have so arranged the parts of the mechanism as to place the reel lengthwise in the frame and in the same vertical plane as 0 the walking-beam. By this arrangement I am enabled to use a reel about ten or fifteen feet long, if so desired,and at the same time, the rope, being distant from the axis of the reel equal to the radius of the latter, Wlll not 3 5 interfere with the operation of the beam, be-

cause it passes to one side of the latter in passing from the reel to the gu1de-sheaves. Another advantage gained by this arrangement of the reel is that in operation the strain,

0 which is often equal to a weight of from live thousand to ten thousand pounds, is equalized upon the frame, while when the reel is placed crosswise the whole strain comes upon the side of the frame, except at the precise point 5 where the rope is being unwound centrally from the reel. Furthermore, by placing the reel and the operating-shaft longitudinally in the center of the frame I am enabled to erect the center of the derrick directly over the center of the frame.

Serial No. 303,078. (No model.)

In the accompanying drawings, Figure l is. a side elevation'of a drilling and pipe-driving machine embodying my improvement. Fig. 2 is an end elevation of the same. Fig 3 isa top plan view, partly in section, on the line a; cc of Fig. 1. Fig. 4 is a detail view of the crank-wheel. Figs. 5, 6, 7 and 8 are detail views of parts thereof. The main frame or platform A is mounted on a rear truck B and on apivoted truck 0, whereby it may be readily drawn fromplace to place. On the rear end of the frame or platform is mounted a suitable steam-boiler D, and immediately in front of the boiler is a steam-engine E, which is preferably of the. vertical oscillating variety.

-A frame F rises from the main frame or platform, the upper portion of the said frame I being extended to form a derrick G and being hinged to the lower portion of the frame in such manner that it may be folded downward thereon out of the way, as shown. In the front side of the frame F are a pair of vertical guides H, and journaled near the rear upper corner of the derrick is a sheaveI, Said derrick-frame is provided on its front side with a pair of vertical guides K, which. arein all essential respects similar to the guidesH.

A shaft L is arranged longitudinally above the frame or platform A and is journaled in bearings M at the front and rear sides of the frame F. Loosely mounted on the said shaft is a hollow tubular drum N, which is adapted to slide longitudinally and to revolve .inde pendently on the shaft. At the frontfend-offig the said hollow drum is a collar-having fthe annular peripheral groove 0, and rigidly Ise;

cured to the drum near the said collaris a worm-wheel Pf Attached to the inneroend of the hollow drum is a disk which is provided with an outwardly-extending lateral annular flange R, the inner side of which has an inclined frictional engaging-surface adapted to form frictional contact with a friction-disk S, which is rigidly keyed to the shaft.

A reel T is loosely mounted on the shaft L on the inner side of the friction-disk S, the said reel comprising a pair of circularheads U and a series of horizontal connecting-bars V, the latter being arranged in the form of a zoo circle. By this construction the inner side of the reel is open, and thereby the sand-pump rope WV, which is coiled on the said reel,ai1d which when in operation is ordinarily watersoaked, will become speedily dried by contact with the air, and thereby the said rope will be preserved from decay.

On the rear side of the reel T is formed a collar having an annular flange X, the said flange being engaged by the bifurcated inner end of a shiftingdever Y, which is fulcrumed to an arm Z, attached to one end of the frame F. The bearing for the outer end of the shaft L has an arm A, to which is fulerumed a shifting-lever B, the inner end of which engages the grooved collar 0. By operating the lever B the hollow drum may be moved longitudinally on the shaft L and the frictiondisk R thereof caused to engage the frictiondisk S, and thereby cause thehollow drum to rotate in unison with the shaft. The handlever Y is adapted to perform the same office for the reel T by moving the latter into engagement with the opposing plane side of the friction-disk S. i

A shaft O, which is arranged transversely on the frame or platform A and is journaled in suitable bearings, has a central portion provided with a worm D, which is adapted to engage the worm-wheel P when the drum N is moved out of engagement with the friction-disk S, and thus enable the said drum to be revolved independently of the shaft L. The said shaft O has a hand wheel or crank E at one end by which it may be rotated.

On the inner end of the shaft L is keyeda spur-wheel F, which is engaged by a pinion G on the crankshaft of the engine, and thus the shaft L is geared to the engine and is adapted to be continuously rotated thereby when the machine is in operation.

To the outer end of the shaft L is keyed a crank cog-wheel H, which engages apinion 1 on a shaft K, the latter being mounted in suitable hearings in the frame or platform A and being provided with a pair of disks L, for the purpose to be hereinafter stated. The wheel H is provided with a pair of transverse guides or ways M, and arranged between the said guides or ways in a radial line and in the face or web of the said wheel are a series of adjusting-recesses N. The said ways or guides M have their inner sides dovetailed, and between the same is fitted a dovetailed block 0, which is, adapted to be moved from the center to the periphery of the wheel. A crank-pin P has its inner end extended through an openingin block 0 and secured to the latter by a clamping-nut R. The said crank-pin is provided with a longitudinal threaded opening, and in the latter operates a set-screw S, the same having its outer end provided with a crank T, wherebyit may be rotated, and having its inner end adapted to engage either of the recesses N, to the end that the block 0, andconsequently the crank pin, may be adjusted to any desired point between the periphery and the center of the wheel 11 and secured to the latter at any desired adjustment. Alever or beam U has its inner end pivot-ed on the spindle or bolt which forms the bearing for the sheave I, the outer end of the said beam extending through and being adapted to play vertically between the guides K. In the outer end of the said beam is mounted a sheave or pulley V. A beam W has its inner end pivoted to the rear side of frame F by means of a bolt or shaft X, and the front end of the said beam extends through and is adapted to operate vertically between the guides II. On the upper side of the said beam is a longitudinallyadjustable extension beam Y, which is secured thereto by means of U- shaped metallic straps Z. A connecting-rod A has its upper end pivoted on the shaft or spindle of the sheave V and has its lower end pivotally connected to the outer end of the beam W. Hence the beams I and U are adaptedto oscillate in unison. A pitman B has its upper end connected to the outer end of the beam W by means of a ball-andsocket joint 0 and has its lower end connected to the crank-pin P by means of a ball-and-socket joint D and consequently the rotary motion of the shaft L, when the pitman is adjusted out of the center of the wheel II, will cause oscillating motion to be imparted to the beams W and U, and the stroke or limit of the movement of said beams will be proportioned to the distance between the centers of the wheel H and of the crankpin, as is obvious, and thereby a stroke of greater or less extent may be communicated to the beam.

A cable E is attached to the hollow drum N and is adapted to be reeled theron and unwound therefrom and passes over the sheaves I and V, the pendent end of the said cable being in the well and provided with the usual weight employed for driving the pipe lining downward in the well or the usual drilling-tools employed in drilling wells. The oscillating motion of the beam U causes the said weight or drilling-tools, as the case may be, to be alternately raised and dropped, and the cable may be played outfrom time to time as the process of sinking the pipe or drilling proceeds by revolving the worm-shaft O.

The said shaft by being geared to the hollow drum N may be also rotated so as to raise the weight attached to the cable. Owing to the fact that the length of the stroke of the beams W and U may be regulated, the stroke of the weight or drilling-tools attached to the cable may be regulated.

Inasmuch as the drum N, to which the cable rope is attached, remains ordinarily stationary while the drilling or pipe-driving process is being carried out, and the pulley V, over which the cable passes, is mounted in and caused to play with the beam U, which operates the driving or drilling tool attached to the cable, it follows that only a minimum dcgree of friction will be exerted on the cable, and hence the durability of the latter will be very considerably enhanced.

When the well becomes clogged with debris, it is necessary to withdraw the drill attached to the cable, and this is accomplished by operating the handle-lever B in such manner as to simultaneously ship the drum N, disconnect its worm-wheel P from the worm D, and cause its friction-disk R to engage the friction-disk S, revolving with the shaft L continuously, and thereby the rotary motion of the shaft will be imparted to the drum and the cable-rope will be reeled thereon and the drilling-tool elevated. When the drilling-tool has been raised to a suitable height, the operatorimmediately returns the drum to its former normal position, with its friction-disk out of contact with the frictiondisk S and its worm-wheel P in engagement with the worm D. The latter serves to hold the drum stationary and prevents it from unreeling the cable unless its shaft 0 is turned by hand-power.

It will be apparent from the foregoing description that the drum may be connected to and disconnected from a constantly-revolving shaft L while the engine is at full operation and without the danger of breaking any part of the machine. In the event that any great obstruction should encounter the drillingtool when the same is being hoisted from the well, the drum N will slip idly on the shaft L, inasmuch as the frictional contact between the disks R and S is not rigid, and thereby injury to the cable Will be avoided. The said disks may also be employed as a brake to control the speed with which the drillingtool is lowered into the well when the drum N is loose on the shaft and the cable is being unreeled therefrom.

The reel T is designed to operate a sandpump when the drilling-tools have been with drawn from the well, and when said reel may be caused to rotate with the shaft L to raise the sand-pump by operating the lever Y and causing the reel to engage the friction-disk S, and when said reel is moved from said disk and thus rendered loose on the shaft it will unreel the sand-pu mp rope and the latter by its own gravity will descend in the well. The friction-disk S, the reel, and the handlever Y also form a friction -brake, which may be employed to regulate the speed of the descent.

lVhen it is necessary to use a temper-screw, the extension Y is moved outward on the beam TV until its outer end is directly over the'center of the well, and the temper-screw is then attached to the outer end of the said extension. W'hen lowering pipes into the well, the extension Y is moved inward, so that it willbe out of the way of the pipe when the latter is in a vertical position.

During the process of drilling a well it is necessary to be almost continually sharpening the drilling-tools, as the latter become rapidly worn when operating in rock, and it is desirable to provide a portable forge adapted to travel with the drilling-machine. To this end I mount a cylinder F on the frame or platform A at one end of the frame F, the same being arranged directly under and in vertical alignment with the beam W. In the cylinder is a piston or plunger G which is connected to and operated by the said beam by means of apitman H A pipe I extends from the lower end of the cylinder and is provided with a check-valve K and a stop-cock L and said pipe terminates in a tank or reservoir M From the latter projects a pipe N having a stop-cock O and to the said pipe is attached one end of a flexible pipe P and to the opposite end of said flexible pipe is attached a nozzle R which is arranged in a tuyere S the latter having a fires pot T at its outer end, as shown. An inletvalve U is also arranged at the lower end of the cylinder. WVhen the beam W is in mo: tion, the piston is reciprocated in the cylinder; and at each downstroke of the piston air is forced into the tank M and becomes com,- pressed in the latter. By opening the stopcock 0 the compressed air from the tank is forced through the nozzle B into the .tuyere, and air is sucked in through the latter and forced through the burning fuel in the fire: pot.- Thus an eificient forge is constructed, which is an indespensable part of acomplete portable machine for the class of work to which the machine is adapted; but the pistonplunger G cylinder F pitman H and inlet-' check valve U perform an additional office,

as follows: When the beam W is in use p and at its highest point, itis then relieved of the weight pendent from the cable E and, as no engine-governor can be used on this class of machines, the engine when relieved of its load tends to accelerate the beam W on its downward stroke, and, if not resisted, would carry the beam W to its lowest point and start it on its upward stroke before the drilling-tools attached to the cable E had expended their force on the rock. Hence when performing the operation of drilling the. stopcock L is closed wholly or in part as the workmen may see proper. On the upstroke of the beam W the plunger-piston G draws the cylinder F full of air. The check-valve U then closes, and the yielding resistance of the air in the cylinderF retards the motion of the engine and regulates it to that extent that the beam V may not return on the upstroke until the drilling-tool has expended its force on the rock. At this point the resistance of the compressed air in the cylinder F acting on the plunger-piston G assists the engine in rais- IIO ing whatever weight may be attached to the cable E The united force of the engine and the resilience of the compressed air thus produces a differentiated motion of the beam W and results in the effect of raising the drill-.

ing-tool in less time than it takes it to fall with a constant pressure of steam on the engine.

Since the drilling-tools are attached to a cable and are carried downward by gravitation only, and the motion downward cannot therefore be accelerated, it is obvious that to increase the number of strokes per minute the speed of the upward stroke must be increased beyond that of the downward stroke. This I accomplish in the above described manner, and am able thereby to make from one-third to one-fourth more strokes perminut-e by reason of the regulating influence of the compressed air in the cylinder, and by allowing a part of the air to escape through the stop-cocks L and O the differentiated movement of the beam W, and consequently the tool attached to the cable, can be carried on to any desired extent, and thus the same weight of tools and power of machinery made to perform one-third to one-forth more work than without the regulating cylinder and plunger.
