fue it known L Roscoe il S'ijePHENe, e citizen of the United. Emme, residing et "Josecleo in the count-y of Los Angeles und n' e. tete 'Calif "niej lieve invented o new useful 'itig, ot which the fol n is specification.
ention relites to drilling rigs ein lugo rotary ling means, either alone or in .combination with e standard rig, :mel t i object the invention is toprovide 'or driving the rotary drilling means f teem the engine, Without the inter1- vo oit Ithe usuel ooun'terehaft; chains l: objects; ot the invention willoppear ruiter, e emomponying drawings illustrate an hoinient of the iniention, and referring Lieto: Figure .i ie e. side elevation of 'e portion oi the, drilling rig. Fig. 2 is a plan View of 'the ports shown'in Fig. l. Fig. 3 is plan view of the'rotery table for the drillrig. is u verticel section on line 5 is e, vert-ical section wiring nieu-ue on. the engine shaft. ie u Aeeoiioifi on .line eL-w8 in Fig. to l and 2, showing; the epplieetioniof the invention to u combine- 'tion rotary sindI standard drilling rig, the flerricli l provided with u tloor 2 on which is mounted, on Suitable supports', a; rotary table for use in rot-ery trillingy Seid table being pri. ideal with the usuel ineens, for efrempley ehu-:lt 5 for engaging with the rod, pipe or operating menos 6 which Curries and .operates the rotary drilling' tool. The eugine 7 is mounted at one side of the fieri-ick and is oonnectetl to operate the rotary table 3 by av direet'rope belt connection in the :following inenner: i clri'vinfg -wheel" S is mounteil on" the shaft e of id engine l.
and u clutch il ie provided on seid Shaft 9 for clutching' the wheel 8 tov theehui't 9 when it ie desired to drive the rotary tehle 3, A tli'iy' rope or eohle l2 passes around the tiriv' ig Wheel S and around the driven wheel 13 on the rotary table. Selci ilrivirw' und driven wheels S end are provideo with pjripiiig; ineens for engaging the rope or cable ue it passes around the smile, to
give en ei'eotive grip suliieiont for driving operation.. The rotary drilling table has to operate et relatively low speed and requires a powerful turning torce 'to rotate it, euch fome being eoneiderobly beyond 'the traue` 1nitting"`eupeoity of any ordinary belt or rictionull driving ineens. it has been usual to drive the rot-ery drilling table by ineens of bevel gears which in turn ore driven from e, eountersheft connect`l eilloy belting to the engine shaft. Such in* termediate connections ure expensive and noisy ated. adel greatly to the dii'iiculty end 'oost of rip-keep of the apparatus. By providing a Isingle rope Connection between the driving engine und the rotary drilling table, l have not only reduced the number of parte required, but avoicl e very considerable source ofliiiculty in the operation of the rig. in orcler to provide the neoeesur'y grip between the Wheel 8 and rope or cable l2, said Wheel S is provided with un annular eeriesrof gripping jews l5, arranged in paire, each pair of jews l5 being pivoted together as shown at 16 to form u toggle, said jaws having outwardly extendingehenks 17 provided with rounded portions 18 engaging in rounded sockets 19 in flanges or annular shoulders 20 and 2l on the wheel. To fucilitete assemblage of the jaws, annuler flange 2l is mede removable and held in position by bolts 22. 'The jaws l5 ure provided `with opposing fifee 23 which are inwardly convergent und adapted to tightly grip the rope -or cable lf2 when suicl jews are pressed toward. the. ii/enter ofthe wheel by the tension of the cable. Stop means 24 on olie or" the jaws engages with u stop ineens; Q5 on the hub 25 of the wheel 8 to limit tie inward movement of the jaws so that they will not bite too tightly into the cable.
In the operation of the rotary table 3 by means of the transmission device above described the rotation of the driving wheel 8 causes the cable or rope 12 to be carried around in the groove of the drive Wheel formed between'the opposing faces of the grippingjaws and the pressure of the rope on these jaws tends to propel them inwardly and pinch them against the rope, thereby giving a tight grip on the rope, which is capable of' transmitting many times the strain that could be transmitted by anordinary frictional engagement. In a similar manner the' rope, in passing around the wheel 13 on the rot-arv table 3, engages in the groove formed between the opposing faces of the gripping jaws on said Wheel, and by its pressure on said jaws causes said jaws to'g'rip the rope and transmit the rotative force to the rotary table. In conse quence of this strong gripping action itis possible to drive the rotary table direct from the engine without interposition of the usual 'intermediate driving connections. I also provide in the drilling rig, for operating the various other rotative parts of the rig by transmission devices similar to those above described, thereby greatly reducinen thenunr. ber of parts required and simplifying the construction and operation of the rig. The shaft 4c() for operatingthe walking beam is mounted on bearings 41 and is provided with a driving Wheel 4t2 which is connected to a Wheel 43 on the engine shaft 9 by rope 24, said Wheels 42 and 43 being provided With gripping jaws similar to those above described. t clutch 44 is provided for connecting Wheel 43 to engine shaft 9. The 'Wheel 42 also operates as a I,crank Wheel being provided with a series of holes at L16 different distances from the center and adapted to receive a oranlr pin 48 on the pitman 4:9 connected at its rubper end to the uf'allring beam 50. @aid s 3 may also carry the sand drum 5l i h is loose said shaft and is adapted to bc connected thereto b y a clutch Anotherwheel on shaft- 40 is adapted to connect to said shaft By a clutch 54, and is connected by a rope 5 to a Wheel 56 on a bull `wheel 57, said `tvheels 53 and 56 being provided with gripvpng jaws similar to those above described on the Wheel 18.
The draw Works indicated at .60, which may also be used in place of a calf Wheel, is connected to the shaft 9 aforesaid by wire rope or cable 6l running over a Wheel 62 on said shaft 9 and over Wheel 63 on the shaft Gil for said draw AWorks or calf Wheel, said wheels 62 and 63 having gripping j aWs similar to those of Wheel 13. .er clutch 65 is with interposed between the shaft-9 and Wheel 62 and the usual brake 66 is provided for the draw Works or calf Wheel.
By the above described construction and arrangement of the part-s all the drilling operations Whether' by rotary 0r standard 0peration, can be performed conveniently and with minimum of obstruction due to the operating parts. The cost and weight of the rig are also materially reduced by the above described arrangement.
