3 Claims. (Cl. 211-60) This invention relates to tubing racks, and

more particularly to an improved tubing rack for supporting well drilling pipe on a derrick.

It is an object of this invention to provide an improved pipe rack of the kind to be more particularly described hereinafter, which is relatively portable so that it may readily be attached to or removed from the platform of a derrick or the like.

Another object of this invention is to provide a tubing rack of this kind having a plurality of spaced apart rods against which and between which the drilling pipes may be supported against the side of the derrick. Pipes held between the rods are securely held in place in any selected order and are held from rolling or piling up against the derrick. The supporting rods are pivotally mounted on a base so that they may be folded back out of the way when all the pipes have been removed from that rod. By folding out of the way, a clear space is provided on the derrick platform so a man may easily reach the next pipes.

A further object of this invention is to provide a tubing rack of this kind having a base which is provided with clamping Jaws for attaching the base removably to the planks which form the platform on the derrick. A fixed Jaw,is formed on the base and a movable jaw is supported on the base, the movable jaw being operated by a lever rockably supported on the base frame, the movable jaw having a certain amount of adjustment to fit various sized planks.

With the above and other objects in view, my

invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a top plan view of a tubing rack constructed according to an embodiment of this invention,

Figure 2 is a transverse section taken on the line 2-2 of Figure 1,

Figure 3 is a longitudinal section taken on the line 3-3 of Figure 1,

Figure 4 is a fragmentary longitudinal section taken on the line 4-4 of Figure 1,

Figure 5 is a fragmentary end elevation taken on the line 5-5 of Figure 1,

Figure 6 is a fragmentary section taken on the line 6-6 of Figure 1.

Referring to the drawings, the numeral l0 designates generally a frame of a derrick used 2 in oil drilling or other drilling operations, elongated pipes as H for the drill rods.

A platform l2 formed of boards 14 is provided at the upper end of the derrick l0 and is supported on the platform forming members IS. The tube rack l6, constructed according to an embodiment of this invention, is adapted to be clamped to the boards l2 for supporting the pipes H beside the derrick Ill.

The tube rack I6 is formed of a rectangular frame I! having tube supporting rods l8 pivotally supported thereon. An elongated rod I9 is fixed on the frame ll by engaging the upper end of supporting arms 20 fixed to or formed on a pair of opposite side members of the frame II.

The rod 19 is supported intermediate the length of the side members of the frame and the pipe supporting rods I8 are rockably mounted on the rod I9. Short sections of tubes or sleeves 2| are loosely carried by the rod IS in close end abutting relation and the supporting rods 18 are fixed to the sleeves 2| by welding or other suitable fastening devices. In this manner the rods 18 are freely rotatable about the rod I9 on the rack ll.

The rods l8 are adapted to extend from one side of the rack I6 so that the tubes or pipes ll may be supported between adjacent rods l8 in their extended position. As the rods l8 extend using from the rack l6 they also extend outwardly from the platform l2. In this position of the rods Hi, the tubes II are adapted to be engaged between a pair of rods [8 for securely supporting the tubes II in selected position. As the tubes or pipes II are removed from the rods l8, the rods may be pivoted or rocked about the rod l9 so that the rods I8 are disposed within the confines of the platform I2. In this manner free access may be had to the pipes l I within the remaining supporting rods I3 by an operator without stepping over the rods [8 from which the tubes II have been removed.

The pipe rack i6 is adapted to be clamped onto the platform l2 and is so constructed and arranged that the rack l6 may be installed on any suitable platform when it is needed and may be removed when all the pipes have been used.

The construction of this pipe rack is such that it may be manufactured alone and need not be formed as a part of the derrick III.

A fixed jaw member 22 is fixed to or formed on the forward edge of the frame H at each end thereof. The fixed jaw member 22 may extend the full length of the forward frame member and is formed of a substantially L-shaped metal bar. The vertical arm 24 of the jaw member 22 is 3 adapted to overlie the side edge of the outer board I and the horizontal arm 25 is adapted to underlie and engage beneath the forward edge of the same board.

A movable jaw member 26 is carried by the rear edge of the tube supporting rack IS. The

movable jaw member 26 is formed of a substantially L-shaped jaw having a vertical arm 21 for abbuttingly engaging the outer edge of the other end board ll of the platform i2.

The lower arm 28 is adapted to clampingly engage beneath the board It below the arm 21. A forwardly extending arm 28 is fixed to the upper end of the vertical arm 21. The connecting arm 29 extends forwardly and upwardly for pivotal engagement with a lever arm 30 rockably mounted on the frame H. An elongated pivot rod 3| is loosely supported along the rear edge of the frame II by a pair of upstanding supporting members 32 at the opposite ends thereof. The lever arms 30 are fixed to the shaft 3i for rocking movement therewith.

An elongated operating lever 34 is fixed on the shaft 3| intermediate the length thereof for the rotation of the shaft by an operator. A means is provided for locking the lever 34 and shaft 3i in selected position relative to the frame H. A spring-pressed keeper 35 is carried by the lever 34 and is adapted to engage in the notches 35 of a segmental arcuate locking plate 31. The looking plate 31 is fixed to the rear frame member of the frame 11. A handle 38 is pivotally mounted on the lever 33 for disengaging the keeper 35 from the notches 36 for movement of the lever 35 and shaft 3 l. The movable jaw member 26 is adapted to engage the side edge of one of the outer boards it of the platform l2 and may be moved into clamping engagement by rocking of the control lever 33.

In the use and operation of this tube supporting rack IS, the front jaw member 22 is initially engaged over the forward edge of the forward plank It. With the control handle 33 moved to a substantially horizontal position so that the movable jaw member 26 is in its extreme adjusted position, the jaw member 26 is disposed as closely as possible in engagement with the rearmost board it. By rocking the control .lever 34 to an erect position or as nearly erect as possible, the crank lever 30 is rocked forwardly carrying with it the movable jaw member 26. The movable jaw member 26 is loosely connected as by a pivot pin 38 to the crank arm 30 and clampingly engages the platform I: between the fixed jaw member 22 and the movable jaw member 26.

For bracing the extended tube supporting rods I8 in their extended position, a notched plate 40 is fixed to the forward edge of the frame I! and extends upwardly therefrom. The plate 40 is formed with a longitudinally disposed series of notches 4| within which the rods I. are adapted to engage in their extended position. In this manner the rods l8, while supporting the tubes II, are supported on. the frame II by both the rod l9 and the plate 40. When the rods ll are moved to their rearmost position they are raised from the notches M and will loosely lie above the shaft 3|.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. A pipe rack comprising a frame, a rod mounted across said frame intermediate the length thereof, pipe supporting rods pivotally mounted on said first rod, a notched member on said frame parallel to and spaced from said first rod, each of said pipe supporting rods engageable in one of said notches in said member in one position and rockable therefrom to an opposite position, a fixed clamping jaw on said frame, a movable clamping jaw carried by said frame coacting with said fixed jaw forclampingly securing said frame on a support therefor, and means rockably carried by said frame for moving said movable jaw.
