2'0 all wha/)t 'it may concer/n.:
Be it known that we, ARTHUR (ur. VVILLARD and l-ViLLIAM W. 711.soN, resldmg at Los .f\ngeles, county of Los Angeles, and State of California, and (hraluaas'll. iViLCox. residing at East Bakersfield, county of lxern,
State, of California. allk citizens of the pling the string oi casing or tubing inentioned with the table or top; and it hast'or its object to provide means of this character which will be superior in point of relative. simplicity and inexpensiveness of' construction, facility in assembling and handling and use, positiveness in operation and durability. and which will be generally superior in eiiciency and serviceability.
Vith the above and other objects in view, the invention consists in the novel and useful provision, formation, construction, combination or association, and mode of applicationand relative arrangement of parts,
'members and features, all as hereinafter described, shown in the drawing and tinally pointed out 1n claims.
In the drawing:

and looking in the direction of the appended Fig. 3 is a detail or fragmentary horizon- `tal sectional View of the same takenon the line mit-m3, Fig. .1. and looking in the direction of the appended arrows;
Fig. 4 is a fragmentary :elevation of a modiiied form of construction;
Fig. 5 is a detail horizont-a1 sectional View, taken ont-he line .M -ml", Fig. et, and looking in the direct-ion of the appended arrows;
Fig. G is a. plan view of a still further modified form of bushing.construction embodying the invention; i
Fig. 7 is a side elevation ofthesan'ie;
Fig. S is a view similar to Fig. 6 of a still further modified form of bushing construction; and l 4 y Fig. 9 is a view of the same similar to Fig. 7.
Corresponding parts in all thegures are designated by the same reference characters.
Referringwith particularty to the drawing, A in Figs. l to 3 inclusive, designates the drive stein or upper section or joint ot a string through which the. boring tool (not. shown) at the lower end of such string is handled and rotated, such drive stem being shown in Fig. l as being adapted to be connected by means of a collar-6 uvith the remaining portions of the string (not shown), but which extends downwardly within the well hole which is shown cased at its top, as at 7. B in these same figures designates the improved means, in one form, for rotatively coupling the stringor stem A thereof with the rotary top or table C. such rotary top or table being mounted by means of Aanti-friction devicesV 8 upon a baseor frame 9 supported at the mouth of the well hole, and having the usualcentral opening through which the boring string is iaised and lowerednnd within which the stem 'A is accommodated, such means B being applied to the stem A within such central opening, shown at 10. The table is provided with an overhanging top flange 1] having an annular rack 11 with thetceth ,of which meshes a gear 'l2 upon a shaft 13 journaled in the frame 9, and upon rotation of whichshat 13 by any suitable means ior applyingy the table C is rotated to cause the rotation of the stem A and the remaining portions ot' the string land boring tool through the agency ofu'tlie-means B. The stem A is shown asgenerally cylindrical in form and bushing half being provided with a laterally -q projecting top flange portion 15 which overlaps the tableor top, such flange portions together comp1-isip, r ,a` continuous annular flange when the bushing halves are assembled together, Each bushing half is. provided at ,each extremity' with a vertical flange, l1G v.which flanges are matched and C joined together in pairs, a flange on each -bushingmhalf being included in each such pair, and each pair of flanges is shown detachably connected together by holdingr means a7 which may consist of a bolt and nut or the like 17, as clearlyshown in Fig. 3. The bushing halves l) and 0 are chamfeed away, vertically, as at 18, to produce the flanges 16, such flanges being thus included within the generally circular geometric figure, in cross-section, of the split bushing constituting the means B. The table or-top yC is provided with opposed channels or ways 19 formed vertically in Athe walls of the central opening 10, and within which are received vertical heads, ribs, or flanges 20 projecting laterally from the-bushing halves and C respectively, said heads or flanges' 2O being capable of vertical play within the channels 19. The stem A is likewise pro# `vided with opposed vertical ways or channels vor grooves 21, ranging vertically or longitudinally of they stem, land within kwhich are received opposed vertical heads,
ribs or flanges 22 formed or provided on the bushing halwes Z) and c respectively and in opposed relation, and preferably in the same vertical plane as the heads or ribs 20. The heads or ribs 22 likewise have vertical play in the channels 21.
' on elevation of the stem A the shoulders or he means or bushing B is applied to the stemA, one half o or c at leach sideV of the same, and such halves are then secured together bythe bolts and nuts or the like 17, this operation being performed with the sten'r A suitably elevated, the ,bushing members being applied above the table C. The bushing may kthen be lowered into the central openinglO in the table, the rib'sor heads 2O taking into the channels or grooves 19, and the ribs or heads 22 traversing the channels or grooves-21 in the stem A. The channels'21 preferably vterminate-in shoulders or stops 23 at their upper ends, and in shoulders or stops'24 at their lower ends; land upstops 24 will co-engage with the lower ends 65 of the ribs or heads 22 and elevate 'the means or bushing B from the table, so that the former may be taken apart and removed from the stem, or allowed to remain thereon and suitable lmeans substituted thereforin the opening 10 for the purpose of holding up the stem or the stem and the string and tools, or for such other purpose as may be in point in the general drilling operation and the se- Nith the bushing or means B assembled and on the stem, or surrounding the same, and
heldin elevated position, if the stem be then lowered the bushing may be caused to interlock with the table Vby means of the" ribs or 80.. I
heads 20` and the channels or" grooves 19, as before stated, so that rotative couple between the stem and the table, by means of the bushing B, is established. The 'top flange consisting of the flange portions 15, .85
resting upon the upper surface of the top or table C, holds the bushing B in worklng position interlocked with the table and with the stem. By means of forming the drive bushing B in two parts, detachabl'y. held to- 90l gether by the holding means d, such bushing may be readily assembled and. applied to the stem, and removed from the same,
laterally of the stem, or the parts may be brought together on the stem and vremoved therefrom without passing the same over` the top of the stem, which would require disconnection of the stem from the ineans of suspension, vliquid supply and the like.
These means of suspension usually include a swivel device the disconnection ofthestem from which is undisturbed, being preferably a permanent working connection. l
The invention therefore provides .for extreme convenience and facility in applying,
handling and Iremoving the bushing. or means B from the string or the stem thereof.
Referring to the modified form of construction shown ini'Figs. 4 and 5,' the same general .mode of operation and advantages attach, but the stem D is shown `as hollow and square, or4 in the form of a square tube, the split bushing E having two halves e and f formed the same as the halves b and c,
with the opposed flanges 16, held together by holding means d' consisting 'of bolts `and nuts "or the like 17, only the two` halves c and fare formed to be brought together and detachably secured by the holding means l in close working fit around the Square stem D,
eliminating any such tongues or ribs or heads as those shown' at 22 in the other iigures; such halves c and f having enlarged top flange portions which together com Astitute an enlarged lateral annular top flange which is devised to overlap the top or tableA C, and to beinterlocked therewith by means 'of pms 26 rising from the table or top and uen'ce of steps entering into the same. .75

aeeonnnodated by suitable openings in such ing or means ll is as enibled iuthe saine manner as; the bushing or means li. the halvesI being held together by the holding means nl, and a collar or the like 2T aty the lower end ot' the stein l) serves to raise the bushing ll out' oi' the central opening in the table upon the elevation otthe stem. 'hen the bushing is lowered into place inthe table, the pins o enter the .suitable openingsl in the flange portion 25 and interloek thel table with the stein through such bushing E. Upon elevation ot' the bushing E the liange portions 23 leave the pinsl 2G.
Referring to the inoditied Aforms ot bushing eonstruetion shown in Figs. t3 and T. and in Figs. S and t). the saine general mode of operation and advantages attaeh` the saineI` being adapted tor use with a square `stem sur-h as the stein D in Figs. l and 5, sue-h .stein being Similarly hollow. or in the forni of a square tube. ln the forms shown in ltigs. t' and T, they lsplit bushing li hasl two halves. yf/ and lr, the plane ot junction of said halves` extending diagonally troni one side ot the square eentral opening 2T at the top to the other side of euch square, eentral opening 2T at the bottoni` such halves being provided with the opposed Vtl'anges 1G which are' held together by holding nii ins-Wfl eon sisting ot' bolts and nuts or the like 1T. .ln
