" PIPE RETAINER FOR DERIR'ICKS.

Application led February 19, 1927. Serial No. 169,655.

. In derricks erected f or the purpose of drilling or operating deep wells it is customary to provide a retaining means for the pipe used in the well. This retaining means includes a board extendingacross the derrick a considerable distance above the floor, and a finger extending outwardly from the board towards the center of the derrick. The pipe being thus retained back of the finger leans against the board and against the side of the derrick. This board, finger,

braces, et cetera, has heretofore been made of wood and was therefore very liable to be Ibroken when the heavy blocks and other well equipment came in contact therewith.

This required considerable delay in replacing the retainer and .necessarily linvolved considerable expense.

An object of our invention is to provide a retainer for pipe in` a derrick which is formed of metal and'jwhich may be quickly and easily placed in position. Y

Another object is to provide a finger for theretainer, the tip of which is so constructed that it will swing when the heavy blocks and the -like come in contact thcre with.

A further object is to provide a retainer which is adjustable to various sized derricks and to various heights in the derrick.

Still another object is to provide a retainer in which the linger may be adjusted to retain small or large amounts of pipe as dc sired. 4 v

Other object-s,` advantages, and features of invention may appear from the accompanying drawing, the subjoincd detailed description, or the appended claims.

In the drawing:

Fig. 1 is a fragn'ientary side elevation of a derrick with our pipe retainer in position thereon. y

Fig. 2 is an enlarged sectional view taken on line 2, 2, Fig. 1. r

Fig. 3 is an enlarged plan view of the fingerwith parts broken away to show interior construction.

Fig. 4 is a side elevation of the finger brace with parts broken away to show in- 50 terior construction. y

Fig. 5 is a fragmentary side elevation of the derrick showing the finger brace plate.

Fig. 6 is a fragmentary side elevation partly in section of .the retainer board.

Referring more particularly to the drawlng:

through said plate and under the beams.

A plurality of holes G are provided in the board 4 so that the hook bolts 5 can be adjusted to suit the particular conditions.

A finger 7 is mounted on the board 4 and extends inwardly into the derrick, the purpose of said finger being to retain the pipe and hold the same in one corner of the derrick. `The finger 7 is-provided with a slot 8 extending lengthwise thereof and bolts 9, 9, ,extend through the slot` into the board 4 whereby the finger 7 may be adjusted to extend a greater or less distance into the derrick thus accommodating a large or small amount of pipe.

A plurality of pairs of bolts 10 arev provided in the board 4 so that the finger 7 may bepadjusted along the boardto suit various conditions. A finger brace plate 11 is secured to the derrick or to some of the beams 3.and extends downwardly to bear against the outer end of the finger 7. This plate is of sufiicient width so that it will bear upon the finger in any of its adjusted positions.

`A finger brace 1.2 comprising a pair of telescoping members 13, 14, the member 1S being secured to the board 4 and the end thereof' rests against one of the corner posts 2. The member 14 is secured to the .finger 7 ad j acent. the inner end thereof. The members 13, 14 may be adjusted relative to each other lby the bolts 15, 15 extending there through and by a suitable number of holes 16 to accommodate said bolts.

A brace arm 17 is secured to the board 4 andI bears against one of the corner posts 2 thereby bracing the vsaid board against movement. It is sometimes desirable to move the finger' 7 to the other side of the derrick in order to stack pipe therein and for this purpose we have provided a plurality of stubs 18 upon which the finger 7 may be mounted, or if desired a second finger may be mounted thereon. The finger 7 is provided with a tip 19 pivoted to the finger y a heavy bolt 20. Small' pins 2l extend n through the tip to hold the same in alinement with the finger 7 but if the heavy blocks or the like should come in contact with the tip while going up or coming down,

-the pins 21 will shear off allowing the tip inwardly from the said board, said boardl and finger being formed of metal, and said finger being provided with a tip on the end thereof, and means pivotally mounting said tip on the linger, and means rigidly securing said tip, said last named means being releasable under high stress.

2. A pipe retainer for derricks comprising a board, means removably securing said board to the derrick, a finger extending inwardly from said board, said finger being provided with a tip on the end thereof, and means pivotally mounting said tip on vthe finger, means adjustably mounting said finger on the board, and means rigidly securing said tip, said last named means being releasable under high stress.

3. A pipe retainerfor derricks comprising a board, means removably securing said board to the derrick, and a finger extending inwardly from the said board, and means adjustably mounting said finger on the board, a brace secured to said board and to the finger, said brace being longitudinally adjustable to compensate for the various positions of the finger.

4. In a derrick including corner posts and horizontal beams secured thereto, 'a metal board, hook bolts extending through said board and under the beams, avbrace secured to said board and bearing against one of the lhorizontal beams secured thereto, a4 metal board, hook bolts extending through said board and under the beams, a brace secured tov said board and bearing against one of the posts, a. finger adjustably mounted on the board, a tip on the finger, a bolt extending through the tip and finger thereby pivotally mounting the tip, and pins extending through the tipV and finger, said pinsibeing so arranged as to shear off under a high stress, a brace for the finger, said brace including two telegcoping members adjustably mounted each to the other, one member being secured to the board and bearing against a corner post, and the other member being secured to the finger.

6. In a derrick including corner posts and horizontal beams secured thereto, a metal board, hook bolts extending through said board and under the beams, a brace secured to said board and bearing against one of theposts, a fingeradjustably mounted on the board, a tip on the finger, a bolt extending through the tip and finger thereby pivotally mounting the tip, and pins extending through the tip and finger, said pins being so arranged as to shear ofi' under a high stress, a brace for the finger, said brace including two telescoping members adjustably secured each to the other, one member being secured to the board and bearing against a corner post and the other member being secured to the finger.

In testimony whereof, we affix our signatures. l ORVILLE R. S'IUlvfl.Y JOHN N. HILES.
