WELL-DRILLING M'Acnnmmr.
Specification of Letters Patent.
Patented. July 7, 1908..
Application filed October 13, 1906. Serial No. 333,850..
T 0 all whom. it may concern:
Be it known that I, HARRY R. DECKER, a citizen of the United States, residing at Houston, in the county of Harris and State ofTexas, have invented certain new and useful Improvements in Well-Drilling Machincry, of which the following is a specification.
My invention relates to machines used in drilling-oil, water and gas wells and has for its object the improvement of the structure of the rotary table used in drilling to the end ing with the driven of my improved machinery will be that the part of it immediately surrounding the opening for the drill stem may be held stationary and locked the outer rim, on which is the gear-face'meshpinion, turns on the stationar portion and has secured thereto clamping devices for turning a length of the drill stem when screwing and unscrewing it. i The details of construction and 0 )eration iully described hereina'l'ter and illustrated in the accompanying drawings in which- Figure 1 1s a central vertical sectional view of my improved well drilling machine, Fig. 2, a top plan view, Fig. 3, a detail view of the clamping arms and their connections.
In the drawings similar reference characters indicate corresponding parts throughout the several views.
1 indicates a suitable base frame on which is mounted the base ring 2 having the race way ring 3 formed therein in which are upper mounted anti-friction bearings 4, the form shown in the drawings being conicahshaped cylinders but it will be a parent that any other form of bearings eitlier anti-frictional orotherwise may be substituted as desired.
5 indicates the master wheel or rotary table mounted on base ring 2 and having a raceway rin 6 in the bottom surface to receive the bearing cylinders 4. The central portion of wheel 5 is formed with an o ening 7 and the inner )ortion of the base 0 the wheel is extended ownwardly as shown at 8 through the opening 9in base ring 2 to serve as a guide for the master wheel when in operation. he side of the wheel 5 is formed with a circumferential groove 10.
11 represents angular clamps secured to the base ring 2 and bearing against the lower surface of groove 10.
12 indicates a ring or rim mounted in the ortion of move 10 and riding on the tops 0 angular 0 amps 11, the underside of said ring or rim being formed with a beveled to the drill stem, while.
16 indicates ears on the up er surface of ring 12 having holes 17 theretl irough, while 18 represents other cars on the master wheel 2 having holes 19 therein adapted to register with the holes 17 aforesaid.
20 indicates a sliding bolt in each ear 18 that is adapted to enter the hole 17 in registering ear 16 to lock the master wheel 2 and ring or rim 12 together when the rotary table is used as a drilling machine.
I 21 indicates guides on the top of master wheel 5 on which are slidably mounted frames 22 having journaled therein 0 linders 23 with shoulders 24 to engage dril stem 25, the
'l he machine above described is used in drilling, the master wheel 2 and ring. or rim 12 being locked together by means oi bolt 20 so that power transmitted through shaft 15 and beveled inion 14 to ring or rim 12 is transmitted t irough-clamps 23 to the drill stem 25 to rotate it.
The drill stem in use in rotary drilling consists of a number of len ths of pipe or tubing joined together by coup ing rings 25. Heretofore in practice theselcngths of pipe have been joined together and taken a art -by hand which requires a great deal of time and besides at times, because of inability to turn the )ipe lengths, it is necessary to cut the coup ing rings to get the lengths apart. My
invention contemplates the combination with the rotary table abwe-describcd of means to clamp the coupling ring 25 to the master wheel 2 and by sliding the bolts 20 out of enga ement with earslii allow the masteravhee 5 to remain stationary and held so by means of a gravity pawl 27, pivotally secured to base ring 2, and engaging a notch 28 in said master wheel, while the ring or rim 12 has secured thereto clamps to engage the length of pipe 25 above the coupling ring 25 and by actuating said ring or rim 12 in the proper direction said length of pi )e may be screwed into or unscrewcdirom the coupling ring.
ltach of the clamps mentioned above consists of a jaw 29 having a cylinder 30 'ournaled therein with circumferential shoulders 30 thereon to enga e the length of pipe, said jaws being mounted on the ring or rim 12 by means of upright arms 31 pivotally secured to the jaws and formed with horizontal extensions 31 a to fit into-the holes 17 in ears 16,
around cou ling 25 and secured to 1 the 'master whee 5 or to an ear 37 on the slde of frame 22 to hold the coupling ring 25 and the casing below it stationary while the length of pipe above the coupling ring is being sctew'ed'into or unscrewed therefrom.
38 indicates a conventional elevator havmg the clamping members 3!), the latch hnk 40 and the links 41 secured to the clamping members 39 and adapted to be secured to a hoist (not shown).
From 'llImahOve description it will be un-- derstood that when the master wheel 5 and ring or run 12 are secured together by bolts 20 the device may be used as a drilling machine but when it is desired to screw or un- ,screw the casing, the bolts 20 are moved from engagement :with the ears 16 and the clamp arms 31 secured in said ears. pipe may then be secured to said arms by means of clamping jaws 2!) actuated by screw sha'l'ls 33 and power being im )art ed to rotate the ring or rim 12 the length of pipe The lengt hs of will be screwed or unscrewed depending on the direction of rotation of the ring or rim 12,
opening and a circumferential groove, and a drill stem mounted in said opening, means to secure said master wheel trom rotation, means to secure the drill stem to the master wheel, a rim'rotatably mounted on the periphery of said master wheel and having an inwardly extending ofi'set engaging the cire umferential rooverther ein, means to rotate said rim, peri orated ears on said rim, arms removably and replace-ably secured in said ears, clamping jawspivotally secured to said arms, notched 011 said jaws, and screw shafts mounted in'said notched earsto actuate said jaws, and a slidingloek bolt mounted on the master wheel to engage one of said ears when the arqns are not in engagement therewith to lock the master wheel and rims together for simultaneousrotation, substantially as shown and described.
In testimony whereof I hereto afiix my signature in the presence of two witnesses.
