DRILLING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 554,940, dated February 18, 1896. Application filed May 6,1895. s a NO- 548,320. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT C. LIEBEN- DORFER, a citizen of the United States, residing at Ottawa, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Drilling-Machines; and'I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in drilling-machines, and has more particular relation to machines for drilling wells.

It consists of certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents a side elevation of a machine embodying my invention. Fig. 2 represents a transverse vertical section through the same. Fig. 3 represents a detail side elevation, partly in section, of the spring-controllin g devices. Fig. 4 represents a horizontal section through the same, and Fig. 5 represents a detail section of the cam and mountings for operating the frictionwheel.

A in the drawings represents the truck, of any suitable construction, by which the machine may be moved to the different fields of operation. B is the vertical frame mounted on this truck, 0 the hollow operating-drill, and D the spring devices for controlling the operation of said drill.

The frame B is mounted on the forward end of the truck, and consists of two vertically and forwardly inclined standards I), attached to the side beams of the truck and held firmly in position by the inclined braces I), also attached to the respective side beams of the machine. A walking-beam b is pivotally mounted between the standards I) and is provided at its rear end with a pitman b pivotally pendent therefrom. The lower end of said pitman is mounted upon a crank-pin b of a crank-disk 19 This disk is mounted on the inner end of the main operating-shaft 19 which is mounted'transversely of the truck and under the rear end of the walking-beam by j ournal-boxes b attached to the longitudinal beams of the truck. This shaft carries a belt-Wheel e, a fly-wheel e, and a friction-wheel 6 the latter being composed of a suitable hub or wheel covered about its periphery with leather or some like frictional material.

The spring devices D for controlling the action of the drill consist of an inverted-yokeshaped frame 61, having lateral lugs d, by which it is attached to the transverse beams of the frame of the truck. The vertical arms of this yoke are provided upon their inner faces with vertical guides (1 upon which the grooved head (1 is adapted to slide and be guided. This head, as shown in Figs. 3 and 4, is provided upon its upper surface with three circular spring-retaining projections (1 the middle one of which is apertured to permit the end of a connecting-rod d to be passed therethrough and secured by a suitable locking-nut.

The under side of the horizontal portion of the yoke is provided with three tubular pendent projections d adapted to support the upper ends of the spiral springs (1 which are interposed between the head d and said horizontal portion of the yoke. The rod (1 passes through the middle one of said projections d and is formed with an eye d at its'upper end. A rod (1 having a turnbuckle c1 connects said rod (1 and the pitman 12 An auxiliary shaft F is mounted on the frame A in the rear of, the shaft b and is provided with a reel or drum f, a friction-wheel f adapted to engage the wheel 6 and a cam-disk f the latter being shown in Fig. 5 with the shaft passing loosely through it to one side of its true center. This cam is provided with an operating-arm f which passes through a slot f cut in the top half of the divided bearingbox f mounted on the truck-beam and in which the cam is set. The arm f is connected to an operating-lever f pivoted at the front of the machine by a connecting-rod f", said lever being provided with rack and pawl securing devices f for holding it in the desired adjusted position.

It will be seen from the foregoing that when it is desired to rotate the drum f the lever f is pushed forward and the shaft F thus forced forward as the cam f revolves. This action will bring the wheel f in contact with the wheel 6 and thus the shaft F will be revolved and wind the rope f upon the drum, the said rope passing over apulley at the top of the frame B and being provided with a suitable hook f.

The drill C is provided with a suitable hollow drill-rod 0 having two twisting-handles c rigid therewith and is screw-threaded at its upper end to work in the temper-screwc the latter being attached at its upper end to the forward end of the walking-beam bya swiveljoint, and a clamp 0 being provided at the lower end of the temper-screw to bind the same in any desired adjusted position 011 the rod 0. Apertures c" are formed in the lower end of the drill-rod, so that the water, sand, Also. ,can pass upward through said rod. WVhen it is desired to rotate the rod 0 to move it downward as the drillingprogresses, the same is accomplished by turning the handles 0.

\Vhen it is desired to raise or lower the drill from or into the well to affix a new point or the like, the temper-screw c is uncoupled from the walking-beam and the hook f S hooked in the same. The drum f is then retated, as before described, and the rope f wound thereon, which will elevate the drill. If desired, when raising the drill the pitman Z) and rod d" may be uncoupled from the crank-disk and the rod d respectively, so that the spring device D will not operate.

By means of the spring device D, I am enabled to produce a sharp quick stroke of the drill, which is more like a rebounding tap than a steady downstroke as the springs are compressedas the drill descends, thus slightly decreasing the force of the stroke and causing the drill to strike with a quick jerking action, which I find produces the best results.

The drillings pass up through the rod 0 and discharge through the handles 0'.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. In a drilling-machine, the combination of a portable truck carrying a suitable frame,

a walking-beam mounted on said frame, a

drill detaehabl y mounted on the outer end of said beam, mechanism for reciprocating said beam, spring devices for restraining the movements of said beam mounted on the frame and comprising a yoke having internal vertical guides and pendent cylindrical spring-s11pporting projections one of which serves as a guide for a connecting-rod, a head sliding on said guides, a bar passing through one of said projections and connecting said head with the walking-beam, and a plurality of coil-springs mounted on said projections and engaging said head, substantially as described.

2. In a drilling-machine, the combination of a portable truck carrying a suitable frame, a walking-beam mounted on said frame, a drill detachably mounted on the outer end of said beam, mechanism for reciprocating said beam, spring devices for restraining the movements of said beam mounted 011 the frame and comprising a yoke having internal vertical guides and pendent cylindrical spring-supporting projections one of which serves as a guide for a conneeting-rod, ahead sliding on said guides, a bar passing through one of said projections and connecting said head with the walking-beam, and a plurality of coil-springs mounted on said projections and engaging said head, a turnbuckle for increasing or decreasing the length of said bar, whereby the tension of the springs is decreased or increased at will and a tackle and winding-drum for raising the drill independently of the walking-beam, substantially as described.

3. In a drilling-machine, the combination of a portable truck carrying a suitable frame, a walking-beam mounted on said frame, a drill detachably mounted 011 the outer end of said beam, mechanism for reciprocating said beam, spring devices for restraining the movements of said beam mounted on the frame and comprising a yoke having internal vertical guides and pendent cylindrical spring-supporting projections one of which serves as a guide for a connecting-rod, a head sliding on said guides, a bar passing through one of said projections and connecting said head with the walking-beam, and a plurality of coil-springs mounted on said projections and engaging said head, a winding-drum and tackle and means for moving said drum into or out of engagement with the moving parts of the machine at will, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

ALBERT C. LIEBENDORFIER.
