Application November 16, 1948, Serial No. 60,215

2 Claims.

This invention relates to an improved floor rack for sucker rods, the primary object of the invention being to provide a. rack for holding sucker rods in a desired position at the derrick floor, while suspended from the sucker rod hanger of the derrick, during the servicing of the well.

A further object of the invention is to pro mote the adaptability of the hanger forming the subject matter of the present invention, to quick installation and removal when service jobs have been started or completed.

Still another object of the invention is to provide means whereby the loose rods hanging in a derrick may be held in a predetermined position out of the path of moving machinery and to also support the rods in such a Way that they cannot cause injury to the worker as sometimes happens when sucker rods are removed and left hanging in the usual way.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings Figure 1 is an elevational view illustrating a rack constructed in accordance with the invention, as racked around a number of sucker rods which have been removed from a well.

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 3 is an enlarged elevational view illustrating the sucker rod clamp of the rack as positioned prior to swinging the rack into contact with a sucker rod.

Fig. 4 is an end elevational view showing the clamp prior to the swinging of the clamp into position in contact with the sucker rod.

Fig. 5 is a sectional view taken on line 5-5 of Fi 2.

Fig. 6 is a perspective view illustrating how the clamp engages a sucker rod to hold the clamp against movement longitudinally of the sucker rod.

Referring to the drawings in detail, the reference character 5 indicates the derrick of an oil well, with which the rack is used, and the reference character 6 indicates a group of sucker rod sections which have been clamped by the device forming the subject matter of the present 9 which have their adjacent inner ends spaced apart as clearly shown by the drawings.

The end walls of the rectangular member 8 are provided with notches Ill that extend in wardly from one of the respective edges thereof, while the rectangular member 9 is provided with notches ll extending inwardly from one of the respective edges of each end wall thereof, the notches l I being disposed in a direction opposite to the notches H]. The main portion of the clamp or rack is in the form of a hook indicated generally by the reference character l2, the hook having the arm 13 thereof welded or otherwise secured to the member 1. The hook is formed with an open end and one end of the hook extends inwardly at M partially closing the open end of the hook and at the same time providing a stop to limit movement of the sucker rod sections held within the hook, should they fall against the side of the hook.

Connected with one end of the hook is the ring it to which one end of the chain i6 is connected, the chain l6 being of a length to be extended around one standard of the derrick 5 as shown by the drawings, and the chain secured in this position, by means of the hook I! which is hooked over the chain. In the use of the device, the rack or body portion is positioned above the box A on the lower end of the uppermost sucker rod section of the sucker rod, upon removal of said section of the rod. In positioning the rack, the rack is positioned against the section of the sucker rod with the sucker rod section diSIPOSBd transversely of the rack within the space between the rectangular members 8 and 9, as shown by Fig. 3 of the drawings.

The rack is now swung to a vertical position, with the notches Ii) and II of the rectangular members 8 and 9, receiving the sucker rod section in a manner as shown by Fig. 5 of the drawings. The rack is now slid downwardly until it contacts with the box A at the lower end of the sucker rod section which provides a stop to prevent further movement of the rack on the section.

The chain It is now positioned around one leg of the derrick as shown by Fig. 2 and the rack is now held in a position to receive the remaining sucker rod sections which must be removed from the well in order to service the well.

With the sucker rod sections held within the rack, it will be obvious that the sucker rod sections will be held in a desired position at the derrick floor while suspended from the sucker rod hanger in a derrick eliminating the dangerous condition existing when loose sucker rod sections hang in the usual way, permitting the sucker rod sections to swing into the path of moving machinery where they frequently become engaged with the machinery to damage the machinery.

With the sucker rod sections supported as described by applicant, the possibility of the rod sections becoming disengaged from the rod hanger in a derrick to cause injury to theworkers, as well as damage to the rods, is eliminated.

It will also be seen that the device is especially adapted for quick installation and removal when service jobs are begun and completed, the device being exceptionally light in weight to render the device conveniently portable.

Having thus described the invention; What is claimed is g 1. A rack for racking oil well sucker rod sections while suspended from a sucker rod hanger of a well derrick, comprising a box-like member having notches extending inwardly from the edges thereof, certain notches being disposed in opposite directions for limiting movement of the box-like member on the sucker rod section with which the box-like member is used, a hook secured to said box-like member in which sucker rod sections of the well are positioned while held in a suspended position, and means for connect- 4 ing the hook member to the derrick, supporting the racked sucker rod sections in a predetermined position.

2. A rack for racking oil well sucker rod sections while suspended from a sucker rod hanger of a well derrick, comprising a box-like section including rectangular members spaced apart and having notches extending inwardly from the side edges of the end portions of the rectangular members, the notches of one rectangular member extending in a direction opposite to the notches of the adjacent rectangular member, said notches adapted to receive a sucker rod section thereby supporting the rectangular member on the sucker rod section, an open ended hook secured to the box-like section and disposed in a horizontal plane in which the remaining sucker rod sections of the wen are held, and a chain connected with one end of the hook whereby the hook is secured to the oil well derrick, supporting the sucker rod sections in a predetermined position; JOSEPH W BRQWN.
