WELL-DRILLINe-MACHINE ATTACHMENT. i

Be it known that I, G'EoRGEHoMBaRm-a citizen of the United States,l residing vat in the county of Livingston and St'ateof Kentucky, have inventedy new and useful Improvements-in 'Well-Drilling-Machine Attachments, vof-which the following is 'a speciication.'`

' This invention relates to well drilling machines'an-d has for' anfobject; to provide novel,y simple and' eiiicient means' whereby the toolactuating main drive wheel vcan be Other objects and advantages will be apparent 'as the nat-ure of the invention is better disclosed and it-will beunderstood that changes within the specific scopeof the v the spirit of the invention. 20

"In this manner it will claim can be made without departing from- In the drawings forming a portion of this specification and in which like numerals vof referenceindicate similar parts in the several views,-F igure 1 is a side elevation of vmy improved well drilling machine.' Fig. 2. isa detail sectional'plan'throughA themain drivewheel. Fig. 3 isa detail side elevationof the drive wheel and itscoperating clutch member.4 F ig. 4 is a detail perspective view of the clutch member.

My im roved well drilling machine-consists preferably of'a wheeled 'frame which comprises a pair of suitably connected spaced beams l and' 2. These beams have mounted thereupon alining bearing boxes 3 in which the Vcylindrical* end portions 4 of a driven shaft are mounted. A main driving o r ac. tuating wheel 5 is mounted upon one of the cylindrical end portions of the shaft and as illustrated the' said wheel carries a" horizontally extendin lug 6. The shaft is formed with a` Iongitudinally extending squared portion 6 upon mounted Aa member 7. The member has formed therein an -annular groove .8 which receives the forked extremity of an operating lever 9. The lever is pivoted upon the frame of the machine and is provided with a rearwardly extendino' handhold 10 which liesin convenient rea of the operator or attendant.4 The ,member 7 has formed there.- Ona radial lug 11 which extends at right angles tothe lug 6 upon the drive wheel 5 an is adapted when the clutch memberv is moved upon the shaft to be thrown into or out of the path of movement of the lug 6,v

which'v is slidably be appreciated that the main drive wheel can be readilythrown into or out of operation.

vThe frame of the machine carries a driving pulley 12 which vis'located in line with the drive wheel 5. A suitable drive ybelt 13 l Patented Dec. 27, 1910. Application led SeptemberlS, 1909." Serial N o. 516,783.

is operatively associated with the pulley '12 "and the drive wheel 5, as shown.

The frame of the machine supports a y standard 14Ev upon which 1is operatively mounted a walking beam 15. This beam supports at one end a drill tool 16 which may be of any well known construction. At

- the` other end the said walking beam is connected with the upper end of a the lower end of said link being mounted upon the pin 18 of a pivotally link 17, operatively crank arm- 19,which latter is secured in any well known manner to one of the ends 4 of the vdrive wheel supporting shaft.

The construction of a well drilling-machineas herein'shown and described is extremely sim-ple and is provided with effective means whereby the main ldrive wheel for actuating the `walking beam can .be thrown into or out of operation. In operation of my improved well drilling attachment, assuming the member 7 to be in the position shown in Fig. 2 of the drawingsthe tooth l1 when the shaft 4A is rotated will be brought into engagement with the lug 6 of the drive wheel 5., it `being understood., however, that' it willy not be constantly or positively engaged therewith. In rotationof the drive wheel 5 it will carry therewith the lmember 7 but incident to the peculiar arrangement 7 and the peculiar construction ofthe driven shaft, the latter' may rate of speed-than the derstood that as soon as passes its center of gravity it will b e free' to revolve independently of the said drive revolve at a greater. wheel 5, it being un.`

the crank portion 19 of the elements 5 and wheel. In view of this constructionthe drive wheel may be driven at .a very low rate of speed and the crank portion 1 9 of the apparatus effectively actuated to impart to the drilling tool the desired drop.

In well drilling apparatus, a frame, a walking beam thereoma drill tool suspended from one end of the beam,

mounted on the shaft, a crank arm supported by the shaft,.connection'sbetween the crank arm and the walking beam, tuating element ontlie shaft and constructed a shaft revolulol'y mounted on the frame, a driven loose pulley*v to` revlve therewith and independently of with the aetuatingfelenientto i'nove tiie'saine the pulley, a lug extending from the pulley, alt/111g extending from the said sliding lectuating element to 13e-engaged by the' lug.
