WELL-DRILLING- MACHINE.

Application filed September 14, 1921. Serial No. 500,486.

Our invention relates to an improvement in drilling machines, pertaining particularly to machines for drilling wells, such as oil, gas and water wells.

The ordinary drilling machine used at the present time is a heavy, expensive implement which is not readily portable, is subject to a great deal of vibration, owing to the location of an engine, Samson-post and mast on the main frame of the machine, which vibration has the effect of wearing out the parts.

It is an object of our invention to provide a drilling machine of light weight, of

relatively few parts, mounted on a frame which is readily portable, and is adapted to be driven by a farm tractor which can also be used'to-transport the machine.

In carrying out our invention, we provide a frame mounted on rolls or wheels so that it can be readily moved, a removable jack-shaft having a reversing pulley for receiving rotary motion from a tractor and mounted on the frame, a band-wheel, a main shaft driven by the reversing pulley of the jack-shaft, a cable spool mounted on the main shaft with means for controlling its motion relative to the main shaft, and means actuated by the band-wheel for driving supplemental shafts and reels.

WVe further provide, as a detached ele- -ment of the drilling-machine, a main mud sill upon which a Samson post and mast are mounted, whereby the weight of both is carried by the sill and not by the frame.

The invention further comprises certain details and construction of parts which will become more apparent as the description proceeds, and will be pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a side elevation of the drillingmachine;

Fig. 2 is a top plan of the same;

Fig. 3 is a top plan partially in section of the main shaft, and Fig. 4 is a vertical section through the machine on line 4- 1 of Fig. 1.

The frame comprised of two longitudinally extending beams 1 and suitable crosspieces 2 is mounted on wheels or rollers 3, upon which the frame may be moved to a desired position, where it is held by means such as blocks 4.

At the end remote from the drilling oporation, a jack-shaft 5 is mounted in bearings and lowering the tools in the well.

6 removably mounted on the frame, and carrles reversing gear-pulley 7. The jack-shaft 'is operated by a belt 8 passing over a pulley We preferably mount a pulley 12 on the jack-shaft for driving a blower 13 of a forge (not shown) or for driving a pump or other auxiliary implement.

At the other end of the frame, we provide the main shaft 14 driven by bandwheel 15 mounted thereon, and which is driven by belt 16 passing over the reversing pulley 7.

Thecable spool 17 carrying brakedrum 18 and clutch 19 is mounted on the main shaft and carries a reel of cable for raising The construction is such that, when desired, the

clutch is engaged, a reel or spool is rotated by the main shaft, and the tools are drawn up. When they are to be lowered again, after cleaning out, the brake on the brake drum and the clutch are both released, and the cable runs into the well regardless of the speed or direction of rotation of the main shaft. The main shaftterminates in a crank-arm 14 and between the arm and longitudinally extending beams of the frame a spur-gear 20 is mounted on the shaft. This meshes with a gear 20 of a shaft 21, which can be used for raising and lowering the well-casing by means of a cable (not shown).

At a point between the jack-shaft and the main shaft. a sand reel spool 22 is rotatably mounted. This spool is carried by a shaft 23, upon one end of which a friction roller 24 is provided. By means of lever 25 and link 26 the roller be forced against band-wheel 15 for rotating the sand reel, and may also be moved away from the bandwheel and against a friction-block 27 for stopping this movement. As is well-known, the sand reel is used to operate a sand bailer 32 is suspended with an underslung effect.

The walking-beam 32 performs the function of raising and lowering the tools in the drilling operation, and is actuated by pitman 33 mounted on the crank-arm 14. The Samson-post in the ordinary type of drillingmachine is mounted directly on the main frame which not only increases the wear and tear owing to vibration, but also is of 7 great weight and interferes materially with the movability of. the machine.

, By mounting the mast and Samson post on the mud-sill 28, we achieve two important results, namelv that the mast is perpendicular in a longitudinal plane, and does not incline toward one side of the machine more than another. As at present constructed, it is customary to incline the mast over which the rope from the cable spool passes so that the end of the mast will be directly over the end of the walking-beam, so as to get a direct vertical movement of the cable and tools. As ordinarily constructed, the mast must incline to achieve that result, as the walking-beam is normally mounted at one side of the drilling machine, and substantially parallel therewith. We have discovered that by mounting the Samson post and the mast both on the mud-sill, we can cause 7 the walking-beam to extend at an angle as indicated in Fig. 2, which will bring the end of the walking-beam under the end of the mast, as indicated. This is an important feature of our invention. By mounting the Samson-post and mast on a mud-sill detached from the main frame, we are enabled to use a much lighter frame than is ordinarily necessary. The effect of the underslinging of the walking-beam on the Samson-post is to decrease the radius over the drilling well at the end of the walking-beam so that the tools are at all times directly over'the drilling-well, which eliminates the whip of the drilling-cable against the wall of the well and the casing therein, which whipping not only wears out the cable but also knocks down cavings on the top of the tools.

Located at the forward end of the machine, and beneath the longitudinal side members 1, 1, are the metal I-beams 33, from the outer ends of which depend the tie-b0lts 34: which engage a substantially V-shaped clamping member 35 bolted by means of bolts 36 to the mud-sill 28. In that the entire weight of the tool, mast, and walking-beam is upon the mud-sill 28, rather than on the outer end of the driving mechanism of the well-digger, it is necessary to anchor the outer end of the driving mechanism against possible upward movement due to the heavy tools that are used. and the lifting exertion imparted to the driving mechanism as the walking-beam is operated. As is obvious from Fig. 1, after the Samsonpost and mast on the mud-sills are properly located, the driving mechanism is rolled up on its rollers or sills 3, and fastened to the mud-sill as described, the same being readily detachable when desirable to move to a new location.

We claim:

1. In a drilling machine, the combination with a frame carrying shafting, of an independent normally detached mud-sill, a Samson-post mounted on said mudesill, a walking-beam mounted on said post, and means connecting the walking-beam with the shafting to transmit a reciprocating motion thereto. 7

2. In a well drilling machine, the combination with a frame carrying shafting, rollers on the frame for moving the frame, a normally detached mud-sill, a Samsonpost and mast mounted on said mud-sill, and means for connecting the mud-sill to the main frame with a rigid connection during the drilling operation.
