Application tiled. March 1.5, 1924. Serial No. 699,525.
To all/whom t may concern."
Be it known that I, RICHARD D. HILL, a citizen of the United States and a resident of Wichita Falls, in the county of Wichita and State of Texas, have invented new and useful lmprovements in Rotary Slips; and
l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make andU use the same.
My invention relates to rotary slips to be used in connection with rotary well drilling, and it is my principal object to provide shps that will hold drill stem securely and not cut the. same, the slips being specially adapted for use with a tool joint having notches on the bottom and a circumferential groove intermediate its ends, the said tool joint being described and claimed in another application.
A further object is to provide rotary slips of this nature having teeth in the top thereof to prevent circumferential slippage' of the drill stem in the slips.
Further objects and advantages will be a parent as the invention is more fully disc os'ed.
With the foregoing in view, the invention resides 'in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing, wherein,
Figure 1 is a partly sectioned side view showing `the slips assembled in a rotary drilling table.
Figure 2 is a top View showin .the slips assembled in a rotary drillin tab e.
Figure 3 is a perspective .vlew illustrating the manner of operation. f
Fi re tis a perspective view of one of the s lps with the teeth removed.
Fi ure 5 is a perspective view of one of the s 'p teeth. i A
Figure 6 is a persective view of the tool j'oint that is specia connection with this type of slips.
The invention comprises a pair ofhalfround members 1 and 1, which are placed in 50 the tapered aperture of the rotary drilli table 2, as/shown, each of the half-roux-i members having an exteriorly disposed flange 3 at the topf' thereof, an'd a projection disposed centrally exteriorly on the said flan `e. 4 and 4 are oblong blocks attached to t e rotary y adapted for use in drilling table 2 with bolts as shown at 5 and 5. 6, 6, 6b and 6c are connecting links pivotedat each end thereof and extending between the oblong blocks 4 and 4 and the projection on the flange 4 of ythe half-round 60 members 1 and 1. The lconnecting links .6 and 6b are provided withy removable handles 7 and 7a for the purpose hereinafter described. It will be noted that the exterior of the halt-round members 1 and 1 ista- 65 pered to conform with the tapered aperture of the rotary drillingtable 2. The lower ends of the half round members are beveled exteriorly to provide a clearance when being inserted in the rotary table. The interior of both l1alf-round members is beveled at the bottom thereof to guide the tool joints on the drill stem as the same is being removed from the hole. The upper-portion of each half-round member is provided with a pair of vertical dove vtail grooves. 8 is -a dove tail tooth of proper size to slide into the dove tail grooves of the half-round members 1 and 1, thus providing means for replacing the teeth as they become worn. The 8 top of the dove tail tooth 8 on the small side is beveled, making the center pointed to er.- gage the notches in the tool joint, as shown in'Figure 6. v v
In operation the slips when disposed in the position as shown in Fi re 3 may be pushed into the rotary drilhng table aperture or they may be inserted b raising the handles 7 and 7. To remove t e slips from the rotary drilling table aperture the handles 7 and 7*? are moved to the osition as shown in Figure 3. When the s ips are in the rotary table aperture the notches on the tool joint which 1s attached to the drill stem mesh'with the dove tail teeth 8 in the 95 half-round members 1 and 1*, when the said drill stem is lowered, thus preventing circumferential slippage of the tool joint and drill stem when the rotary drilling table 2 is being rotated. A 10 Rotary slips involving this principlemay be used without the teeth 8, making the interior of thehalfdound members smooth, and eliminating the notches in the lower end of the tool` joint, it is'then necessary, however, to use a wrench onthe said tool joint to prevent circumferential sli page when the rotary table is being rotates.
It 1s belie.ed from the foregoing description thenature and advantages ort the nu vvention will be readily apparent, however, I wish to'indicate clearlyv that Ido not limit myself to the specific construction, herein shown anddescribed, and that such other changes mayy be resorted to, when desired, as fall within the scope of what is herem -f claimed.
. lVhat I claim i-s:
1. In a rotary drilling table, a air of conically shaped semi-circular mem rs removably mounted therein and adapted to ,en-
circle a drill stem; a plurality of tooth memence of said inner face, said pockets being open at the top and ada ted to-receive coactin lugs therein forme on the drill stem.'
` 2. n a rotar conically shape semi-circular members removably mounted thereon by means of out- Wardly projecting lugs,` levers connected to said luffs and to other lu s o n the face of the table,jsaid semi-circu ar membershavgrooves in their innerv faces, teeth of re atlvely soft `'material removably mounted in said grooves, coacting lugs removably secured to the stem of a drill and adapted to enga e the teeth set in the semi-circular l mem I'S. l
