TUBE RACK FOR DERRICKS.

Application filed an 1,

Our invention relates to tube racks for derricks, although it'will be understood that other devices such as sucker rods may be retained by the rack if desired.

Heret'ofore the practice has been, in pulling tubes, to stack the tubes on a derrick against thevfinger board, and, after one row of tubes has been so stacked, other tubes are stacked on the first row of tubes. The stacking of tubes in this manner is dangerous in that the tubes are liable to slip oil and injure the operator.

It is therefore the principal ob'ect of our invention to attach a rack to -t e derrick In the accompanying drawings, which illustrate one form ofmy invention,

Figure 1 is a vertical sectional view of a derrick showingthe application of our invention.-

Figure 2 is a horizontal sectional view taken on the line 22 of Figure 1. m Figure 3 is an enlarged plan view of the rack showing the manner of supporting the same on the derrick, a portion of the derrick and a portion of the rack being shown in section.

, Figure 4 isa detailed front elevation of the structure shown in Figure 3, and Figure 5 is an enlarged detail view, particularly in I section, showing one of the tube retainers. Referring to the accompanying drawings,

A represents a; derrick of any preferred construction, which, however, includes the up- "ht 55 dth crssbar or tubin mg 5 an e g 4 frame. Clamping nuts 2222 are'associated board 6.

Our rack, which is designated as a whole by the reference letter B, is removably attached to the tubing board 6.

plate 7 is secured to the tubing board 6 by screws '8 or other .suitable fastening means,

' gnut 22 is'a cup 24. Arranged around each and carried by 'andextendin forwardly from the late 7 is'a plurality 0 bolts 9 hav ing threa ed outer ends for receiving clamp in nuts 10. I

' 7 he rack B includes an attaching plate 11 'which' is provided with perforations to re- A supporting 1928. Serial No. 274,317.

ceive the bolts 9. The attaching plate ll'is positioned against the supportln plate 7 and is rigidly secured thereon by t e clampng nuts 10. Rigidly secured to the attaching plate 11, either by welding or other suitable means, is a plurality of tube supporting frames 12. Each frame is formed'of a strip of flat metal which is bent into U shape tov form parallel arms 1313 and a connection portion 14, which-constitutes the attaching I frames end, and an open front end 15. The 12 are arranged side by side in horizontal plane so that all of their open ends 15 ex-' tend outwardly from the tubing board 6.

The tubes 16 are-adapted to be positioned within the several frames 12' with the ends. of lthe tubes resting on the floor of the der r1c It is desirable to provide the several frames 12 with means for yieldably retaining the tubes against movement and yet permitting" withdrawn or inserted the tubes to be readil (1 To this end we have -whenever so desire provided each frame 12 with a plurality of spaced yieldable retainers 17. A series of t of ese retainers is supported on each arm 13 each frame 12. These retalners are arranged m ,s aced relation and extend sub stantially t roughout the length of the frame. Furthermore, the retainers of one series are disposed directly opposite the retainers of the other series. Consequently, the several tubes positioned within a given frame 12 will be respectively retained between four retainers, two of the retainers being on one arm Bend the other two being on the other arm. i

Each retainer is preferably'formed of the U-bolt 18, whichv includes parallel arms 19 19 and" a curved connecting portion 20. 'lh'e arms 19 are threaded, and the free ends ere'of extend through rforations 21 formed in the associated Sid arm 13 of the 7 the oup24 is coral s ring 25, which functions v to yie dably hold t e retainer in its outermost ositiom. v 7 Al ough we have shown a rack consist- 110 also that the frames may vary in length so ing of four frames 13, itQwill be understood that a greater number or a lesser number of frames may be employed 1f desired, and

as to support any desired number of tubes.

Located within the arms 1313 of each frame between the connecting portion and the innermost retainers 17, and rigidly secured to the attaching portion is a curved rest 26 which cooperates with the adjacent pair of retainersto hold the first positioned tube in proper position.

From the foregoing, it will be readily un derstood that as the operator withdraws the tubes he positions one end thereof" on the derrick floor and swings theupper end of the tube into one of the frames 13, the upper end of the tube being forced inwardly from the open end 15 past the several retainers until the upper end of the tube is positioned at the inner end of the frame. The succeeding tubes are then positioned in the samegeneral manner, until all the tubes are positioned within the rack. It will be apparent that the tubes may be readily withdrawn whenever desired, and that these tubes when retained by the rack will be held against accidental displacement and consequently avoid any injury to the operator.

We claim:

1. In a tube rack for derricks, the (301m bination of a frame having parallel arms and an open end for receiving a plurality of tubes, and a plurality of spaced yieldable tube retainers extending laterally from one arm toward the other.

2. In a tube rack for derricks, the combination of a frame having parallel arms and an open end for receiving a plurality of tubes, and a plurality of spaced yieldable tube retainers extending laterally from each arm toward the other, the retainers on one arm being disposed opposite the retainers on the other arm.

3. In a tube rack for derrieks, the combination of a frame having parallel arms and an open end for receiving a plurality of tubes, and a plurality of spaced yieldable tube retainers extending inwardly from one arm, each retainer comprising a U-shaped bolt having spaced arms and a curved connectin f portion, the retainer arms having sliding connection with the frame arm, stops on the retainer arms, and springs intermediate the stops and the frame arms.

,4. In a tube rack for derricks, the combination of an attaching plate, a plurality of pairs of spaced parallel arms extending from the plate and arranged in'a common plane, and yieldable tube retainers supported on each arm of each pair of parallel arms and extending laterally toward the other arm.

In testimony whereof, we have hereunto subscribed our names.

QUINCY C. WEBB. GEORGE CARLTON.
