non-HANGER.

Specification of Letters Patent.

I Patented Aug. 19, 1919.

Application filed November 18, 1918. Serial No. 262,979.

To all whom it may concern:

Be it known that I, KENNETH D. FULLER, a citizen of the United States, residing at Whittier, in the county of Los Angeles and State of California, have invented new and useful Improvements in Rod-Hangers, of

I which the following is a specification.

In the pulling of rods from oil wells, it is common practice to laythe stands of rods upon the ground, or two support them from a rack comprising a long slotted plate in which ten or twelve stands may be hung. In the latter case, the shoulders of the couplings rest upon the rack, and it is necessary to pry out the rods from the rack, in order to be able to attach the elevator. In either case it is diflicult to attach the elevator, much time and labor being required.

It is an object of this invention to provide a hanger of simple construction, by which a stand of rods may be quickly and easily secured to and supported by a hanger,

and whereby inexperienced help may be employed for the purpose of hanging the rods.

It is another object of this invention to I provide a hanger of such character that several may be installed compactly in a der rick, and whereby a stand of rods may be secured to or released from a hanger in an expeditious manner, without interference with other stands which are hanging.

I accomplish these objects by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a hanger, a part of the cable connecting the eye and hook being broken away, and a rod coupling being shown in dotte lines. Fi 2 is a front elevation, and Fig. 3 is a section taken on the line 33 of Fig. 1.

Referring more particularly to the drawing, the hanger is composed of three elements. These are an eye A, a flexible line B, and a hook C. A coupling supported by the hanger is indicated by D.

The eye A consists of a ring 4 adapted to be passed over a supporting bar disposed in a horizontalposition at the top of a derrick. A socket 5 is formed therein, and is provided with a tapered bore, into which is introduced the line B. The line is preferably a wire cable, and is secured in the socket of the eye by Babbitt metal.

The hook C has a socket 6 provided with a tapered bore, and cable B is babbitted nary therein. The shank 7 of hook C is off-set from socket 6. The opening in the hook is square and of such dimensions as to fit snugly around the squared portion of the coupling. The hook proper 8 is offset by being bent at an an le to the shank, as best shown in Fig. 1. pon the hook is an elevation 9 designed to engage the coupling shoulder, so that there is a three point suspension for the coupling.

In practice, there will be about twelve hangers supported from a bar attached at the top of the derrick. This will accommodate twelve stands of rod, each of about eighty flelet. This is suflicient for the ordi- Assume that a rod is being pulled from a well, and the elevator has been attached to the rod below the squared portion of the coupling. The rod is then elevated to the top of the derrick. A hanger is next grasped by the attendant, swung out and hooked on the squared part of the coupling below the shoulder. The flexible cable ermits such handling of the hanger. he stand may then be lowered so that the hanger supports it, after which the elevator is detached. The hanger and rod may now be swung around to a position out of the way of the elevator and other stands of rods, which may be later pulled or installed. For this purpose the rods may be swung back of a crossplece on the derrick, the latter holding the rods away from the elevator, when in position to raise or lower rod.

To release rod from a hanger and install in a well, the hanger and rod may be swung from behind the crosspiece. The elevator is then attached and the rod elevated. weight of the stand of rod having been removed from the hanger, the elevation 9 carries the hook of the ban er away from the rod thereby releasin tie hangerand making it unnecessary lor the attendant to unhook it from the rod. The hanger may then be swung back out of the way.

It is obvious that I have provided a safe,
