SLIP FOR DRILLING RIGS, ETC.
Application led Julyv 18,
ment in one direction, but will permit movement in the o posite direction, with latch 'means for hol lng the slips in inoperative position when desired.
provide means for preventing mud, sandand other material from interfering withthe operation of the slips and to permitl such material to pass from the casing which carries the slips.
This invention also consists in certain other features of construction'and in the combination and arrangement of the several,
parte, to be hereinafter fully described, il-
ustrated in the accompanying drawings and specifically pointed claims.
- In describing` my invention in detail` refout in the appended erence will be had to the accompanying drawings wherein like characters denote like 2n or corresponding parts throughout the several views, and in which Figure 1 is an elevation of one form of the invention.
Figure 2 is a plan view thereof. 3 Figure 3 is a ure 2.
Figure 4 is a section on line 4-4 of Figure 3.
Figure 5 is a longitudinal sectional view u showing a part of the device with a rod or pipe passing through the same and with the slip in inoperative position.
Figure 6 is a fragmentary internal view of a portion of the slip casing, showing one n of the slips.
Figure 7` is a sectional view through the `hinge of the two-part casing.
Figure 8 is an elevation showing a modification. 4l Figure 9 is a longitudinal sectional view through this modification and showing the casing provided with a cover.
Figure v10 is a transverse sectional view through Figure 8.
In these drawings, A indicates a casing which is formed of two sections 1 and 2 which are hingedly connected together at one side of the casing by the pin 3 which is l fastened in place by the rivet 4 and at the `ends in communication with the slots.
sl1p or jawv 9 is placed in each recess and section on line 3-3 of Fig- 1927. Serial No. 205,470.
other side the two casings are 'fastenedgtogether by the removable pin 5so that by removing thispinf the casing can be opened to permit acoe'ssto the interior thereof. The caslngmisfformedV with, internal recesses 6 Whichfejxtend longitudinally and with transyversely arranged slots .7, each of which com- *munic'ates with the lower end of each recess. A further object of the inventiony v,is to Th e lower part of4 the caslng is provided with threaded holes 8 which have their upp` has laterally extending'trunnions 10 at its lower end which fit in the slotl and these trunnions are heldin the slot bythe threaded pins11 which and have their reduced plain ends passing through the slot there being two pinsfo'r each slip.
A coil spring 12, placed between the rear of each slip .and the casing, tends to move the slip toward the center of the casing and causes it to grip a pipe or rod, such as shown at 13. the slip moving about a horizontal axis formed by the trunnions. As shown, the slips each taper downwardly to their lower ends so that when they are forced against a rodor pipe by the springs, the plpe yis held against downward movement but is free to move upwardly. A latch member 14 is pivoted to the upper end of each slip and has a projection 15 thereon for engaging a keeper recess 16 formed in the upper part of t e casing to hold the slip in inoperative position, each member 14 having a handle 17 formed on its outer end. The slips are so arranged in the casing that a space 18 is formed between the rear faces of the slips and the rear walls of the recesses and each space is enlarged by a V-shaped groove 19 ormed in the rear wall of each recess, this oove extending around the lower end or the' slip and communicating with the interior of the lower portion of the casing. Thus mud, sandor water will pass from the recesses and not interfere with the `movement of the slips.
pass throughthe holes BH and engaging the trunnions,
the second form of the invention the casing is provided with a reduced cylindrical end A so that it can lit in the casing head and used in pulling tubing and the like from wells or putting the tubing back 'in the well.
From the foregoing it wi'll be seen that these slips will firmly hold the rods or tubes from falling back into the well in being pulled therefrom, but will permit the rods or tubes to pass upwardly. It will also be seen that when the slips are not to be used, they are pulled back into their recesses by means of the handles 17 on the latch members 14 and are held in this position by the rojections 15 of the latch members engaglng the keeper recesses l.
It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fal'l with- 1n the scope of the appended claims.
What I claim is 1. A device of the class described comprising a casing, slips or jaws pivotally arranged in the casing, springl means for forcing the slips or jaws toward the center of the casing so as to prevent downward move-- ment of an object passing through the casin but permitting upward movement of said object, latch means connected with the slips or jaws for holding them in inoperative position, means for preventing material from collecting in the casing behind vthe slips, such means comprising grooves formed in the casing in rear of the slips and having their lower ends extending into the lower part of the casing below the slips.
2. A device of the class described comprising a casing, slips or jaws pivotally arranged in the casing, spring means for forcing the slips or jaws toward the center of the casing so as to prevent downward movement of an object passing through the casing butJ permitting upward movement of said object, latch means connected with the slips or jaws for holding them in inoperative position, means for preventing material from collecting in the casing behlnd the slips and a detachable cover for the casing.
3. A device of the class described comprising a sectiona'l casing, means for hinging the sections together at one side of the casing, a pin for fastening the sections together at the other side of the casing, said casing having longitudinally extending recesses and laterally extending slots, each slot communicating with the lower end of each. recess, a slip in each recess having trunnions at its lower end fitting in the slot, a pair of screw pins for each slip, said pins passing through threaded holes in the lower end of the casing and extending through the slots and engaging the trunnions, each slip tapering toward its lower end and having its inner face toothed, a spring for forcing each slip toward the center of the casing,v a handle pivoted to the upper end of each slip and having a projection thereon for engaging a part of the casing to hold the slip in inoperative position. l In testimony whereof I affix my signature.
JOHN HOLMAN sMrrH.
