of boringpipes, and alsov equipped with means for driving a suitable wrench for gripping the upper section of boring-pipe for rotating it. Figs. 2 and 3 represent the, same turntable as that shown in Figs. 4 and 5, but showing it equipped with a diderent type of turning means adapted foruse in drllling. inasmuch as many -of the details of the construction illustrated in Fig. 1 are the same as those of the construction illustrated in Figs. 2 to 5, ll have not deemed it necessary to illustrate in detail the structure of Fig. 1, which will be readily understood Vfrom my descriptionof the. same dea vices in connection with Figs. 2y to 5. I wilL' therefore,.irst describe the construction .of

of Fig. 1 is the preferred construction.

' Referring. now"to Figs.`2 to 5 and Figs. 8, 9 and 92425 indicates a framework, of any suitable type, located at the upper end of a.v well, having mounted thereon a bed-- plate 26. Rising from the upper face ofthe '70 Figs 2 to 5, even though the construction bed-plate 26 is a heavy, circular ring or base 27, upon the upper edge of which is suitably mounted a turntable or rotary 28 which comprises a downwardly-extending' sleeve 29 inside of the base 27.

Annular bearing rings

30 and 31 with anti-friction rollers 33 interposed between them are used between the rotary 28 and the upper edge of the base 27, the ring 31 being in the form of an angle-iron or steel with a vertical flange rising from the outer edge.

As best shown in Fig. 3, the sleeve 29 of the rotary 28 is provided near its lower edge with an annular groove 33 into which a block 34 is adapted to be moved by'means Y of a set-screw 35 mounted in the base 27 at onev sideI thereof. As will be readily undertood, the block 34 serves to 'hold Athe sleeve 9 locked down in position relative to the base 27. If desired, a plurality of such locking devices maybe used.

The rotary 28.is provided at each side with uupright posts 36 ,removably mounted in sultable sockets in said rotary, as is ordinary practice' in machines of 4this type.

The rotary is also provided on its unde face with an annular gear 37 with which meshes a gear 38 fixed upon one end of .a shaft 39 jourraled in a suitable bearing 40y rising from the .bed-plate. As will be readily unas p' derstood, uponthe .application of power to a the rotary 28 will the shaft 39 in one direction or the other,

lbe rotated in a corresponding direction.

' Coming now to the meansfor turning the boring-pipe for boring purposes,41 indi- `catesa boring-pipe extending down into the well, having connected. to its upper end a l boring-bar 42` by means of a screw-threaded ing-bar 42 is provided with a longitudinal opening therethrough communicating with the interior of the hollow pipe sections 41, whereby a supply of water may be lied through'the string of boring-pipes to the drill at its lower end for washing up the borin s as the work progresses.

" Re erring-now especially to Figs. 4 and l5,--it will be noted that the plate '46' is removed from the rotary, a plate 49 being substituted, the plate 49 being mounted in the bed-plate 26 or the base 27 and being held against `rotation by means of a plurality of teeth 50 engaging suitable notches 51. l The plate 49 has vrising from it a housl ing 52 which iscored out conically, as best shown in Fig. 5, for slidably supporting a plurality' of slips in the `torm of wedges 53 about the boring-pipe 41. In the construction shown, four wedges are used, and that is the number I prefer to employ. Each of the wedges 53 is. provided with a T- 4shaped rib 54 adapted to slide freely.v in a vsuitable groove in` the housing 52, whereby the wedgesare moved toward and away from the boringpipe-as they are moved up and down longitudinallyof the boring-pipe. a

Aswill be appreciated from' an inspection of Flgs. 4 and 5', the wedges 53 are of two different types,rone having teeth extending .vertically as'shown' in Fig. 8, and the other having teeth extending horizontally as shown in Fig. 9, the two types of wedges being arranged alternately about the housing 52. .-By this arrangement two wedges having vertically-extending teeth are provided diametrically opposite each other adapted to hold the boring-pipe 41-against rotation relative to the housing, and two bf the wedges having horizontally-extendv ing teeth are located diametrically opposite eachother adapted to hold the lboring-pipe against downward movement into the-well. As best shown in Fig. 5, 55 indicates a plate bolted to the plate 50 and revolubly supporting a conical shell 56 by means of a hub 5 7 connected therewith. The shell 456 is pro-l vided also with an annular gear 58 meshing with a gear 59 fixed upon.a short shaft 60 journaled in the housing 52 at one side thereof. The shaft 60 is provided at lts outer end with a socketed head 61 adapted to be rotated or rocked through the medium of a shaft 62 slidably mounted in a'suitable bearing in the base 27 and -in a standard 63 rising from the bed-plate 26. The shaft 62 is provided at its outer end with a turningdevice 64 oit'l any approved type, by

which the

shafts

62 and 60 can be rotated for turning the gears 58 and the shell 56 on a vertical axis about the boring-pipe 41. l

As is best shown in Fig. 9, the wedges 53 are provided with outwardly-,projecting pins 65, shown diagrammatically in Fig. 5 as working in diagonally-positioned slots 6G in the vshell 56, `whereby said wedges are raised and lowered by an appropriate turning of the said shell.

The wrench used for turning the upper end of two united sections of boring-pipe in l connection with the holding means shown in .Fig 5, comprises two handles 67-68 (see Figs. 10 and 11) .adapted to be engaged by the upright posts 36 of the rotary for turning' purposes. The construction of the wrench is suchvthat it is adapted to bind tightly upon the boring-pipe for causing the pipe to. rotate with the rotary.

' With the turntable 28 providedwith the plate 46, as-shown in Fig. 3, and with the boring-pipe 42 connected by means of a coupling 43 with the boring-pipe 41, upon the application of power to the shaft 39 the boring-pipe will be rotated for boring purposes, as will be readily understood, the engagement .gf the boring-pipe 42 with the rotary 28 bein such that the boring-pipe l41 can rise and fa l freely relative to the rotary. When boring has progressed so as to bring the upper end of the boring-bar approximately to the plate 46 ofthe rotary, the boring-bar will be disconnected from the .boring-pipe 41 and another section of boring-pipe will be interposed between the boring `bar and the line of connected sections of boring-pipe. Whenever in the use of the devices heretofore described it is desired to remove the whole'line of boring-pipe sections from the well, the plate 46 is removed and the plate 49 is placed in position as `shown in Figs. 4 and 5, the boring-bar 42 being also laid aside-for the time being. The line of boring-pipe sections is then raised' by means of hoisting means (not shown) to bring one of the couplings 43 between two sectionsv of the boring-pipe into theuposition shown in Fig. 5. The weight of the wedges 53 is such that they automatically settle into gripping position -to hold the section of pipe both against longitudinal Lasarte y am movement and against rotation. By the use of a wrench placed in position upon the section above the coupling 43 the upper section of boring-pipe is unscrewed from the lower section and laid aside for future use. The line of boring-pipe sections is then raised by fineans` of any suitable means to bring another of the couplings 43 into the position shown in Fig. 5, the wedges 53 being adapted to give upward to permit the passage of the coupling, whereupon the operation as just described is repeated. For placing the line of`boring-pipes in the well, thev operation issubstantially the reverseof that just described, the rotary being driven in the opposite direction with the wrench inverted so as to turn the successive upper" sections for screwing the sections together instead .of for unscrewing them. In order to move the wedges 53 apart to permit the passage of the couplings 43 downward be tween the wedges, the turning-device 64 1s to be rotated, as will be readlly understood,-

turning the shell 56 and forcing the wedges upward and outward. Upon the passage of one or more couplings 43, as desired, the turning-device 64 is re easedto permit thev A' Wedges 53 to settle into grippingposition,

as will be readily understood. Upon the completion of the installation ofthe boringpipes in position,l the plate 49 will be removed and the yplate 4 6 and the boring-bar 42l will be placed in position ready for lthe work of boring to proceed.

Coming now to Figs. 1, 6, and 7, which show the preferred orm of construction, the correspondin parts are indicated by the 'same ,reference c aracters fbutj with the 4ad- 74 being substituted therefor having acon-l dition of an exponent a. In this construction, the rotary 28 is dispensed with a rotary siderably greater vertical height than the lli ushown in Fig. l a top rotary 28 so asvto brin the upper closureplate of the rotary suii'ciently above the bed-` plate that the plate v49V and the parts carried thereby can be retained in position durof the plate 75 is substituted for the collar 44 of the construction first described, the.

' ff plate t7 being provided with a collar or hub 78corresponding in a general wayl to the collar 44- andada ted to Work with the-boring-bar in precise the same manner. The wrench illustrate in Fig. l also di'ers slightly from that shown in Figg, but they operation is, generally speaking, the same.

llnasmuch as the operation of the device ofl construction employing two pairs of oppo- 'extending ring, a rotary mounted thereon 'comprlslng a sleeve extending down inside 'of said rlng, means at one side of said base Fig. 1 is the same as that ofthe device o Figs. 2 to 5, except that it is not necessary to remove the' 'plate 49n when the device is to be used for boring purposes or to remove the plate when the device is to be used 70 for withdrawmg or replacing a line of boring pipes, it is believed that it is unnecessary to further describe the operation herein.

While I have shown in my drawings a sitely-disposed coperating wedges, it Will beunderstood that I do not wish to limit myself to that construction except as hereinafter specilically claimed.: Such a construction comprises a wedge (either of the Wedges) provided with suitable coperating lneans (the other Wedge) -for accomplishing the desired result. It will be understood t that I do not Wish to claim a second wedge as the coperating means except as particularly specified.

. That which I claim asmy invention, andV desireto secure by Letters Patent, is,-
