' Application filed Novemberl l, 1921fser ia1 No. 514,940.

To aZZ whom-it may concern.

Be it known that I, Moa'roN 'IIOMER lVlAGiE, a citizen of the United States, re-

siding at Los 'Angeles, in the county of Les 5 Angeles and Stateof California, have invented a new and useful Tool- Feeding Means forDrillingRigs of which the following is a specification.

This application is, in some respectsa 10 continuation of my application for a patent on a temper-screw; SerialNoAtOLQM, filed August ith. 1920, and allowed 'May 16th, 1921 and involves improvements on said application in which the drilling line'isf perated by achain driven worm-gear arrangementi .Y

used in well drilling rigs having a walking beam for operating thetools.

In the art as heretofore practiced, the tool carrying end of the walking-beam when in position for operating the toolsQhas a verpendici'ilar motion of fror n two to four feet; and when the engine end otsuch beam is down or? of the crank pin, thus raising; the working end of the beam, the up and down movement may be four or five feet, more Or less. with lateral movement in the neighborhood of two feet, for-withdrawing the temper-screw from over the 'llOlGyiIO- ward the Samson post to ,QIVG clearance for other operations in'the hole. f

In present practice and in said applica-f tion, the drilling clamps which carry the two links that are suspended from the two ends of a yoke or swivel that is connectedv to the bottom of the temper-screw, or the quently causes the line to strike the side of the casing, thus tending to wear both the line and the casing," and in addition to this creates a disagreeable vibration and a jerky drilling mechanism; and the resulting lateral strain sometimes causes breakage of the temper-screw. Y i

, quired to turn the temper-screw and to feed drilling;- line and tools are suspended by.

sitive feeling that the driller needs'to note operation which is injurious to the rig and "same less energy of bothc'engine' and-driller,

and will reduce the't me-andefi'ort of get} In operatingline 'tOOlS, he driller is a; I

55. the tools into the hole as the hole is'drilled; and this requires the use of a three decked stool. commonly; v all d th d i n knowledge bench so thatat the'jbeginningf of the operation, he can stand on the upper deck to turn the cross-bar of 'thetemper" screw, and as the drilling proceedsandisaid L cross-bar lowerspgthe driller ca take'fs'uc cessively lower decks until hefcan; operate. from the floor; 77 U When the temper-sorewlhas thus been lowered, it is necessaryto'move it backup the line to the former startingpositionfrela tive to the beam. 1 The invention relates to the mechanism' In order to do this the slack ofthe line is t 7 taken up by the bull-wheehthus*support- I ing thetools'fr om 'the'crown pulley; then the temper-screw is unclamped fromthe line andzelevatedto' its it'ormenposition; after which it isagain clamped to thefline," the bull-wheelreleased and the line abovethe clamp given the necessary slack and then the work proceeds as before. With present practice a heavy counterweight is employed to assist in returning the temper-screw to its elevated position? and said counterweight is'attached to and I has to be carried up and downby the walking-bam at each stroke," Such"'cimnter; weight adds to the expensejof the drilling rig and to the expense ofinstallation; and also adds additional strain to the woi'king'" parts and additional load tofbe carried by the walking-beam bearing "and by-the engine; and also when running the rig rap,- idly, 'it causes the temper-screwfto "jump 1 from its bearings thus adding wear and danger of breakage {it also causes excessive vlbratlon. It also interferes 'wlth the sen in, order todetermine the exact conditions *to' be met at the bottom of the hole.

' Fiu-thermore' the operation of lifting the temper-"crew in the'lnescnt practice requires the attendance of, and isdiiiicult work'for, two men. 1' i Anobject of this invention is "to provide means whereby the operation of thedrilling rig willbe more even and steady: will con v ting the ,temper screw back from the lower position to the starting position, and will also allow the temper-screw to be lowered 'more or less danger of accident on account ofthe heavy load, necessary to be liftedin shifting the position of the jars; and an object of this invention'is to make-provision whereby the raising or lowering of the tools or jars can be accomplished practically by one operator.

Anobject is to provide superior means for dispensing with the multiple deck stool necessary with the present, practice. The invention i broadly new, pioneer in that'Iuse a worm rack for suspending, raising, and lowering the tools.

Ifhave so constructed the appliancethat the temper-screw for handling the-tools is of an endless screw construction and acts on a worm rack; and furthermore, in that provision is made for unshipping the worm and handling the worm'rack by a pinion for rapidly raising and lowering the worm rack when the tools are suspended from the derrick. v d

An object is to weight of the tools avoid all danger of the caus ng the temper-screw to spin, and the tools to get away vtrom the driller; and also to avoid the necessity of alternately tightening and loosening the set screw heretofore provided to. prevent such spinning of the temper-screw and falling of the tools.

Other objects, advantages, and features of invention may appear the accompanying drawings, the subj oined, detail description, and the appended claims.

The accompanying drawings illustrate the invention.

Figure l is an;. elevation of my invention in aewell rig,=fragments of which are shown. The parts are in-posi-tion with the worm rack up and supporting the tools, and in working position.- Y

In the drawings B indicates the bullwheel; the Samson 30st; W, the walkingbeam; C, the crank; thepitinan; andD the derrick, all of whichare of the usual construction.

R is a rack bar from which the line is suspended. The rack bar is supp rted by an endless screw or worm 1.

Fig. 10 is a view analogous to Fig. 9,

In carryingout this invention I construct the temper-screw in the form of a rack supporting and operating worm 1, a worm rack 52 meshing therewith, reins 3 supporting the worm and journaled on a top bearing 4 which may be variously constructed and is shown in the drawings as a shaft upon which a box 5 carried by the reins 3 is swung;

and the worm is revolved by a worm gear 6, and. its driving worm 7; said drivingworm is mounted on a shaft 8 drivenby a pulley or sprocket wheel 9and endless'chain 10 which depends nearly to the floor 11 upon which the workman stands to operate the teinper-screw.

The worm rack forms a vertically mow,

able bail support and is provided at its lower end with a centrally arranged bail bearing 12 from which is hung a single bail l3 having a central bearing 14: to rest on said bail bearing; the top hearing at ,4, 5, and the bail bearings being practically alined vertically. A. suitable clamp 15 is provided to forming a bracket attached to the bottom oi the reins 8. j

1A spur rack 19 is fixed to andextends along the worm rack 2, and a pinion 20 thereforis fixed to the shaft 8, and the parts are so spaced that the rackbar R provided with the spur rack and the worm rack may,

be operated alternately by the worm 1 and the pinion 20. a

zontal transversely shifting yokes 22, 23 which are arranged at the top and bottom of the frame 18 and are :"provided with vertical guides 24 for the worm rack.

Said yokes 22, 23 are connectedtogether by the horizontal shifting screws 25, 26, the

driven sprocket wheel 27, sprocket chain 28 by the crank 30. a

ing yokes horizontal y so that by turning the crank 30 the worm rack will be unshipped from the worm land the spur rack 19 will be meshed with the pinion 20. I T

The worm 1 and the pinion 19 are both operated by the endless chain, 10 over sprocket wheel 9, and the endless chain is prevented from jumping ofl? by-the' house ing .31. a

The worm 7 is revolved by the shaftiS that is revolved by endless chain 10 to oper-Y ate the worm gear 6 which revolves the worm 1.

When the worm 1 is in engagement with the worm rack, the operation of theichain will raise and lower the rack with power; and in drilling, the worm will support the tools at the predetermined depth relative to the bearing 4, except when the chain 10 is.

operated to raise orlower the tools.- When the chain is not being run the worm rack 2 is locked and will support the tools at a. predetermined depth and the chain under the operators hand will-give the operator the touch or feeling necessaryto determine, the condition of the work at the bottom of the hole, and the driller will move the 'chain 10 to lower the tools as'the work proceeds.

When the tools are suspended by theline v 16 from bull-wheel shaft 32 over crown pulley, not shown, as indicated in Fig. 3, the

against such action, a s ring operated thumb ratchet 33 is provide to engage the spur rack "19to prevent descent of the worm rack and to allow easy ascent of the same when thepinion isoperatedfor that purpose. 1 1

When it is desired to lower the worm a rack, the thumb ratchet will bedisengaged- I .i

by. the operator, a'ndthe chain operated to lower said worm rack.

By the arrangement above described, whenever the tools are supported by the worm rack, the line hangs vertically and the thrust of a the walkingbeam. does not. cause the line to vibrate and whip the sides'of the hole, and the operator has easy control of the tools. .-The sensitiveness of the endless Y chain 10 to the operation at'the bottom of, '80 posestas with the ordinary temper-screw. and driving sprocket wheel 29, all operated the hole is as complete for all practical purg The operator can 'manipulate' the *tools i while standing on the floor throughout all Power applied by the crank 30 will simul-' taneously and equall slide both of the shift-' positions of-the clamp 15. I
