WELL-BORING MACHINE.

SPECIFICATION forming part of Letters Patent No. 739,860, dated September 29, 1903. Application filed February 28,1903. fierial No. 145,570. iNo model.)

T0 on whom it may concern.-

Be it known that I, DANIELA. HARMON, a citizen of the United States, residing at Ingraham, in the countyof Clay andState of Illinois, have invented a new and useful WVell- Boring Machine, of which thefollowing is a specification.

My invention relates to machines for boring wells; and it consists in the various features hereinafter described and more particularly claimed and as illustrated in the accompanying drawings, in which Figure 1 is a perspective view, Fig. 2, an enlarged vertical section of the base and operating mechanism; Fig. 3, a plan view of the guide-clamp; Fig. 4, an elevation of the holding or gripping clamp.

' Similar characters indicate like parts throughout. the'several figures of the drawings.

The letter F designates a base-frame, which may consist of a central cylindrical member 10, provided with a vertical opening 11, through which the auger and auger-shaft pass, and the lower and upper cylindrical reduced portions 11 and 11, respectively, and intersecting arms 12,forming a cross and each having successive lower and upper steps 13 14, respectively. To these stepsare secured metal track-rings 15 16, which 'also serve as At opposite ends of the arms are secured the lower ends ofderrick members 17 17, connected at their upper ends by a rod 18, uponwhich is supported a pulley 19, and at their intermediate crossbraces 20 by a cross-beam 23, just above the head ofa person standing on the machine-platform.

Upon the lower track 15, about the portion 11 of the central member, operates a windlass-drum 24, preferably provided with separate rolls 25, journaled in its under side for side of the platform preferably lies in close proximity to the upper face of the Windlass,

and the two elements may be compelled to rotate together'by a pin 33 or connector extending through an opening 34 in the platform into a recess 35 in the drum and be held into engagement with said recess by a spring 36. The pin is preferably provided with a projection 37, operating in a slot 38 in the platform, so that when the pin is raised out of the recess and slightly turned about its axis it will lock it in this position and allow the Windlass to rotate independently of the platform. Radially from the platform extends a draft-bar 39, to which may be attached an animal to furnish power to the machine.

Above the platform at opposite sides of the are formed alined ways 4141. Oneach side of the ways of each standard are flanges 42, provided with a vertical series of alined notches to receive at various heights a fulcrum-bar 43. In the ways of the standards move rolls 44, turning upon the ends 44 of a bar 45, having formed in it one jaw 46 of a clamp member 0, the movable jaw 47 being pivoted to the bar at 48 and being shown as provided with a screw 49 for drawing it toward its companion to permit it to be clamped about the auger-shaft 50.

A second clamp O, the function of which will be hereinafter described, is also shown encircling the auger-shaft. As illustrated, this consists of a pair of jaws 51 51, connected to each other by opposite pivot-bars 52, about which they turn. A depression 53 may be formed in each jaw and be faced with leather or other suitable material. A notched segment 54, pivoted to one member, extends through a slot and cooperating witha pin 55 in the other allows the clamp to be maintained' fast upon the pipe.

Upon the Windlass is coiled the rope 70, which passes over a pulley 72, mounted upon the end of a brace 73, extending from the frame, and finally up over the pulley 19.

Upon its depending end the rope carries a clamp O for raising the sections of the augershaft.

In the operation of the machine the anger is started through the openings in the frame, Windlass, and platform, and the clamp-bar O is secured upon the auger-shaft to compel it auger-opening rise standards 40 40, in which to rotate with the platform, while allowed to move through the same by the travel of the bar-rollers in the standard ways. Now if the pin 33 is raised to permit the independent movement of the platform this may be rotated bya draft-animal, and, pressure being applied to the clamp 0 through a suitable lever coacting therewith and with the fulcrum-bar, the augur will be advanced into the earth, the material removed rising through it. The clamp C is shifted upon the shaft whenever necessary. When a section of the shaft has gone down, the clamp O is loosened and the clamp 0 set upon it and by this is supported upon the fulcrum-bar until a new section has been connected. This being accomplished, the clamp C is released and the clamp O restored, and the boring goes on as before. When it is desired to remove the shaft from the hole, the clamp C is lowered by its rope to the proper distance, preferably to a coupling, the yield of both jaws readily permitting this, and the platform and Windlass being connected by the pin the Windlass is rotated by the draft-animal. The upward pullupon the clamp throws it into operative engagement with the pipe, causing it to be held firmly between the gripping members and causing the entire shaft to be raised. This continues until the coupling between the sections rises above the platform. The lower .section is then caught and held by the clamp C while the coupling is disconnected, and the upper section is grasped by one of a series of clamps S3 of any suitable form swinging upon the cross-beam 23. In a similar manner all the shaft-sections may be withdrawn and held by the clamps 83, with their upper ends resting against the derrick, rendering it unnecessary to lower them to the ground and leaving all convenient for immediate use. After the auger is drawn from the well to empty the dirt it is again lowered into position in the following manner: The rope and windlass allow the auger-box to descend until it has passed the fulcrum-bar, after which it is lowered without the assistance of either the rope or Windlass. The shaft is caught by the clamp O at the fulcrum-bar and the clamp C" is removed if it can be reached. If it is too high, the pin 33 is raised, which allows the Windlass to unwind and the clamp C to descend within reach, when it can be released. The arms 51 of the clamp O are held by the hands, letting the shaft lowerat anyspeed desired to the proper distance. When pressure is exerted upon the arms, the shaft stops. The notched segment 54 is then brought into engagement with the pin 55, and the clamp is locked in position, preventing further downward movement of the shaft. The next section is then coupled on, the segment released, and the shaft then allowed to slide down through the clamping-arms, so that another section can be fastened on, if necessary.

It is to be understood that although I have described my preferred form of construction claimand arrangement of the several parts, yet I do not desire to be limited to the exact arrangement or details of constructions, as numerous changes may be made without departing from the spirit of my invention.
