' WELLDBIILLING 'Massima To all. whom 'it may concern:

Be it known thatLfTnoMAs H. Keim, a'

gheny andv State of Pennsylvania,have invented certain new aint'nseful Improyements in VellfDrilling Machines, otwhich the following is a specification, reference being .had therein 'to the accompanying drawing.

This invention relates to well drilling ma` ehines, and more particularlytothat type of machine designed for drillil'lg oil and gas wells.

The primary object of this invention is to provide a drilling machine for drilling well holes of great depth, the machine being con-V structed with a positive driving mechanism whereby lost motion is eliminated and a maximum degree of eliiciency obtained with Another object of this invention is to provide an oil drilling machine of a portable nature that can be made permanent at the side of an oil well. whereby the machine can be safely used without subjecting the inaehine to the vibratory stresses and strains set up when the machine is in operation.

A still further object of this invention is to provide an oil drilling machine with an interchangeable walking beam and spudding mechanism.

lVith the above and other objectsin view which will more readily appear as the invention is better understood, the same consists inthe novel construction, combination Aand arrangement of parts to be hereinafter de scribed and then claimed. Referring to the drawings -Figure l is an elevation of a machine constructed in accordance with my invention, the mast or derrick thereof being partly broken away, Fig, 2 is a plan of the machine with the mast or derrick in horizontal section, Fig. 9 is an t) enlarged side elevation ofthe chain drive forming part of the machine, Fig. 4 is a plan of the same, F ig. 5 is an enlarged front elel vation of a tension device for the walking beam of the machine, and Fig. G is a side elevation of the same.

Referring to the drawings in detail, the reference characters -1 and 2 designate longitudinally extending bars and the reference bars together forming thereby a frame rectangular in contour and constituta-Xle 8, the latter serial'no.' 484,419.5

ing'the body-portion of themach'ine. Y The "body-gordon isv supported i1-pon the holsters 6 and the l*former being carried by the rear being provided with Wheels 9. The-front of the axl fifth wheel 10 and thereon the 'front being providedwith a further has mounted Wheels l2.

13 designates an engine of the ordinary and Well known type which is supported upon the bars 3 and 4 for driving a crank shaft 14 journaled in bearings 15 mounted upon the barsA l and 2.

16 designates a balance Wheel carried by the crank shaft 14 adjacent to the bar, While 17 designates a flanged sprocket wheel carlia'ied by the crank shaft 14 adjacent. to the ar 1S designates a sand reel journaled in bearings 19 carried by the bars 1 and 2, said sand reel having a brake wheel 20 contiguous to the bar l, also a small flanged sprocket wheel 21 contiguous to the bar 2.

designates bearings carried by the bars 1 and 2, and insaid bearings is journaled a shal't Upon the shaft 23 is mounted a reel 24, and slidably mounted upon said shaft.- is a. clutch member 25 adapted to engage -the hub 2G of a gear wheel 27 loosely mounted upon the shaft 23.

28 and 29 designate flanged sprocket wheels carried by the shaft 23 adjacent to the bar 2 and over said sprocket wheels and the wheels 17 and 21

travel sprocket chains

30 and 31, said chains being of -a type calculated to provide a positive drive with a minimum amount of lost motion and energy.

32 designates a clutch mechanism used in connect ion with the sprocket wheel 29, which is loosely mounted upon the shaft 23, whereby said shaft can be operated independently of the sand reel 1S.

33 designates ascrank carried by the end of the shaft23 adjacent to the fran'le l, said cra-nk having a plurality of openings 34, whereby a Wrist pin can be adjustably connected to the crank.

36 designates a shaft journaled in bearings 37 carried by the bars 1 and 2, s aid shaft supporting a large drum 38 having one end thereof provided with a brake Wheel 39, while the opposite end is provided with a large gear wheel .40 adapted to mesh with the gear wheel 27. In connection with the e of the'v machine'is, .indicated bythe reference characterll and supports the bolster 7, the said front axle l1A brake wheel 39, a brake band 41 is used, said band having one-end thereof secured to the bar 1, as at 42, while the opposite end is connected to a brake lever 43, pivotally conlare mounted two

cranks

48 and 49, the crank 49 being connected by a pitman 50 to the crank 33, while the crank 43 supports a revoluble grooved wheel51 adapted to engage a drilling cable 52 attached to the drum 38. Y

53 designates a samson post carried by the transverse bar 5. Fulcrumed upon the sam-1 son post 53 is an angularly `disposed walking beam 54, the rear end of said walking beam supporting a pitman adapted to be connected to the crank 33, while the forward end of the walking beam supports a tension device adapted to be used in connection with a cable 52 and a temper screw (noty shown). 56 designates av tee head, of a temper screw frame, said head extending above the forward end of the walking beam 54. Clamped upon the stem 57 of the temper screw frame is a cross head 5S adapted to rest in the transverse groove 59 of the walking beam 54. The cross headV 58 is provided with two sets of upright guide pins 60, the pins' of each set being vconnected at their upper ends by a fixed plate 61 and a movable plate 62, these plates confining the tee head 56 between the pins 60. 1Eincircling said pins between the cross head 53 and the plate 62 are coil springs 63. 1

64 designates masts erected upon sills 65, said masts being suitably supported in an upright position by guy-wires (not shown). 66 designates foundation sills which are positioned beneath the ends of the bars 1 and 2 after the machine has been located, said sills bracing the machine and supporting the same similar to a separator machine. I prefer to move the machine into specially prepared roads or ditches whereby the bed 0f the mcahine will be in proximity to the ground and can be easily braced by the sills 66.

The elements 58 to 63 inclusive constitute a tension device adapted to relieve all excessive stresses and strains upon the drilling cable 52 when the Ysame is in operation. The elements 47 to 51 ingliisive constitute a spudding device which Yis used in starting a hole, said spudding device being generally used for the first twenty-five or fifty feet drill. After the hole has reached such a depth, the pitman 50 is disconnected from the drank 33, and the pitinan 55 connected to said crank, whereby the walking beam 54 can bei.oscillated tol raise and lower the drilling cable 52 in the hole previously started by the spudding' device. Through the medium of the elements 13, 32, 25 and 43, the operation of the machine can be easily controlled.

It is thought that the operation and utility of, the machine will be lfully understood without further description, .and while in the drawings forming a part of this application there is illustrated the preferred enibodiments of my invention, l would have it understood that the detail construction thereof can be varied or changed as to shape,

roportien and manner of iassemblagewithout departing from the spirit of the invention.
