Yof the same, reference being had to the accompanying drawings, forming part of this speciflcation.

- This invention relates to improvements in portable well-drilling machines.

The object of the invention is to provide a portable well-drilling machine which will be more compact in form and more readily controlled in its operation than those heretofore constructed.

`Another object of the invention is to so construct a well-drilling machine that the sand line and tool lines may be operated by drums independently carried on the gearshafts.

Still another object of the invention is to provide a portable well-drillin g machine with means for rotating and reciprocating the drilling-mechanism.

The invention consists in certain peculiar features of construction and combination of parts which will hereinafter be more fully described and pointed out in the claim.

Figure 1 represents a side elevation of the improved Well-drilling machine. Fig. 2 represents a plan view of the forward portion thereof, partly in section, to show the driving-gear with the sand-line reel and tool-line drum in combination therewith, as well as the devices for governing the operations of the drum and reel. Fig. 3 represents a sectional view of one form of drill used in the improved machine and illustrating its action on the material through which the boring is made.

vSimilar numbers of reference designate corresponding parts throughout.

In the drawings 5 indicates a substantial base, or frame-work, mounted on wheels; to

lthe forward portion a pole carrying whiffletrees maybe secured for use'in attachingl horses when the machine is to be moved,- mounted in the rear end of the frame 1s a steam boiler 6 and on the frame is an engine 7 provided with a drive-shaft and a belt-pulley, the valve-chest of the engine being connected with the boiler by suitable pipes;- also mounted on the frame is a pump 8 provided with pipes, or hose, 9 land 10. From the four corners of the frame extend the vertical-standards 11-11 and 12-12 which may be suitably braced,-to the upper ends of the rear standards 12--12 are pivoted the ends of the side-bars 13-13 of a walking-beam frame, the forward ends of the bars being connected by the cross-piece 14 in which the eye-bolt 15 lis fastened, in these side-bars are mounted shafts 16 and 17 carrying pulley- sheaves 18 and 19. To the upper ends of the standards 11-11 are pivoted the lower ends of the sidearms 20-20 of a derrick-frame provided at the top with pulleys 21 and cross braced by the step-pieces 22-22. To the upper portions of the derrick-arms 20 are pivoted the supporting-braces 23-23 the rear ends of which are removablyv clamped to the upper ends of the standards 12-12. I

On the forward portion of the base, or frame, 5 are mounted side-frames 24-24 in the upper portions of which are journaled two parallel shafts 25 and 26. On one end of the shaft 26 is secured the belt-pulley 27 connected by the belt 28 with the driving-pulley of the engine,on' this shaft 26, between the supporting-frames,`is rigidly fastened the gear 29, and loosely mounted on this shaftfis the sand-line reel 30 having end disks and a grooved-extension 31, the disk of the reel 30 nearest the gear 29 being adapted to closely fit against the side of the gear when the reel is forced sufficiently farin that direction, the reel being operated by the lever 32 pivoted to a stud or extension, secured to a side-frame and having curved-arms 33 the ends of which engage the groove in the extension 31 of the reel. When it is desired to wind the sand line on to the reel 30 the lever 32 is operated to throw the reel-disk into frictional contact with the gear 29, the lever being then held until the reel has been rotated by the gear sufliciently to wind up the required amount of line.

Mounted on the ends of the shaft 25, beroo yond the end-frames 24, are crank-arms 34- 34, to each of these crank-arms is pivoted a connecting-rod 35-35 the upper end of which is pivoted to a corresponding side-bar 13 of the walking-beam f1'ame,as one of these side-bars is connected with the plunger-rod 8 of the pump 8 the rotation of the shaft will operate the pump. Also mounted on the shaft 15 is the large gear 36 which intermeshes with the gear 29 and is driven thereby.

Loosely mounted on the shaft 25, between the gear 36 and its opposite bearing, is the tool-line drum 37 having end disks one of which is adapted to be forced into contact with the side of the gear 36 while the edge of the other is furnished with a grooved-iiange 38 on which the friction-band 39 bears,the

drum is furnished with a grooved extension` 40 and is moved along the shaft 25 by means of the lever 41 pivoted to a stud on the frame and engaging the groove of the extension 40, the lower end of the lever being pivotally connected with a screw-shaft 42 passing through a screw-threaded perforation in the side-frame and operated by the hand-wheel 43. One end of the friction-band 39 is fastened to the surface of the frame 5 while the other is secured to the brakelever 44 which is pivoted tothe extension-frame 45. By the rotation of the hand-wheel 43 the drum is moved along the shaft 25 toward and away from the gear 36 5 when in contact with that gear, the drum is rotated by the frictional contact, and the tool-line, passing through one of the pulleys 2l and secured to the drum, is wound on the drum,--when it is desired to lower the tool the drum is drawn out of contact with the gear 36 and is governed by means of the brake-lever 44 and the brakeband.

The small shaft 46, shown in dotted lines in Fig. 2, is j ournaled in bracket-bearings secured to the frame 5 immediately below the shaft 25. At one end this shaft has a small gear which intermeshes with the gear 36, and on the other end is mounted the bevel-gear 47, this gear in turn intermeshing with a similar gear 48 on the inner end of the shaft 49 journaled in the bracket 50-50 secured to the frame 5 and haying on its outer end' the beveled-gear 51.

From the forward end of the frame 5 and firmly secured thereto extends the frame 45 having a vertical-bearing in which the central-sleeve of the beveled-gear 52 is j ournaled; this gear intermeshes with and is driven by the gear 51, the bore of the central sleeve of this gear 52is sufficiently large to allow the passage of thedrillingtube 53, and in the material of the sleeve is formed a longitudinal key-seat to receive the key 54, the outer surface of the tube 53 having also a similar seat into which one edge of the ket fits to prevent theindependent rot-ation of the gear 52 around the tube.

When the drilling-machine is to be used in combination with a vertically-reciprocating tool, the extension-frame 45 and the gear 52 may be removed and the tool-line may be either fastened to the eye-bolt 15 or, after being carried through the pulley 21, then under the sheave 18 and over that marked 19, is fastened to the tool-line drum 37, in either case the rapid vibration of the Walking-beam frame serves to rapidly lift and lower the tool ;-where the tube 53 is sufficiently large to form a proper casing the tool may be lowered through the open top of the tube.

The pipe, or hose, 9, leading from the pump 8, is shown as connected with the top of the tube 53, but this may be disconnected at will, being secured thereto by the ordinary coupling-device. y

When drilling withthe tube 53 the material is usually cut away in the shape of an annular channel surrounding a core which has a diameter about equal to theinternal diameter of the tube, in this case I' iindthat the boring is greatly accelerated bythe use of steel or other hardened balla-indicated in Fig. 3, or coarse emery placed in the bore after a short distance has been drilled, the material being thus ground away by the balls, or emery, duringv the operation of the tube.

In transporting the drilling-machine the derrick-supports 23 are released from the standards 12-12 and the derrick is then folded down upon the standards which support the rear ends, the supports23 being then turned forward and secured to the side-bars of the walking-beam frame.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- The combination with the platform, or frame, 5 an engine, or motor, 7 having a beltpulley mounted thereon, the pump 8 and the side-frames 24 also mounted on the platform, the standards 11-11 and 12-12 secured to the corners of the platform, a .derrick the side-arms 2O of which are pivoted to the standards 11-11, supports 23 pivoted tothe sidearms of the derrick and securedto the standards l2--12, a walking-beam frame the sidearms 13-13 of which are pivoted to the stand ards l2-12, and a plunger working in the pump and connected with one of the sidearms 13, of the shaft 26 journaled in bearings of the side frames, the pulley 27 and gear 29 secured on said shaft, the reel 30 having the grooved-extension 31 loosely mounted on the shaft, a belt connecting the pulley 27 with that of the motor, the pivoted-lever 32 for reciprocating the reel, the shaft 25 having the gear 36 intermeshing with'the gear 29 journaled in bearings of the side-frames, crank-arms 34--34` secured to the ends of this shaft, connecting-rods 35-35 pivoted to the crank-arms and to the bars of the walkingbeam, the drum 37 loosely mounted on the IOC IIO

shaft 25 and having the friction-flange 38 and the grooved-extension 40, the pivoted-arm 41 engaging the groove of the extension, the

band is secured, as and for the purpose described.

In Witness whereofI have hereunto set my screw-shaft 42 having the hand-Whee143 for hand. l
