FBANKS, OF TULSA, OKLAHOMA, ASSIGNOR OF THREE-FOURTHS T TIDAL OIL COMPANY, OF TULSA, OKLAHOMA, A CORPORATION OF OKLAHOMA MOUNTJJT G FOR CALI WHEELS OR THE LIKE Application filed December 13, 1929. Serial No. 413,813.

My invention relates to derricks of the type and pumping oil wells, more particular y to a mountin for the cal; wheel constituting an element 0 the derr1c Derricks of this t pe are fabricated in sections at the mill and erected on the well location, the corner le s, cross girders, braces, girts, etc. being bolted, riveted, or clamped together to form the derrick structure, and the floor being installed after erection of the main derrick parts.

As it is necessary; to center the cable or wire line whereby the tools, tubing, rods, bailer, etc. are let into and removed from the well hole with the cable, it is essential that the calf wheel on which the cable or wire line is reeled be located in proper alignment with the well hole. Consequently, it is the object of my invention to provide a mounting for the calf wheel which may be installed after the derrick is erected and adjusted relative to the well hole before being permanently attached to main derrick parts.

In accomplishing this object, I have provided. improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:

Fig. 1 is a rspective view of the lower portion of a errick including a calf wheel mounting of my improved construction.

Fig. 2 is an enlarged side elevation of one of the calf wheel posts, illustrating its attachment to the floor sill and lower girder (shown in cross section).

Fig. '3 is a detail pers ctive view of the clamp members for attac ing the post to the 'rder. Fi 4 is a similar view of the tie plates for attac 'ng the post to the derrick floor.

Referring in detail to the drawings:

1 designates corner legs, 2 a lower cross 'rder, 3 the floor, and 4 the floor sills of a errick of ordinary construction; the floor having the usual opening 5 through which tools and equipment are let into and removed from the well hole.

6 designates the calf wheel posts supported in spaced relation on the derrick floor 3, and

attached to the girder 2 to retain the posts in proper spaced relation and rigid on the derrlck. The posts 6 are preferably of channel iron of a length to fit snugly between the floor and girder with the channels facing outwardly, and the flanges 7 reinforced by plates 8 which may be bolted or riveted thereto. The posts are preferably anchored to the floor by tie bars 9, consisting of short lengths of angle iron, flanges of which are bolted to the webs of the post channels and other flanges attached to the floor sill 4 by bolts 10, plates 11 being preferably interposed between the lower ends of the posts and the floor to pro: vide smooth and firm seats for the posts.

The upper ends of the posts are clamped to the girder 2 by clamp members on the respective posts including paired arms 12 and 13, each having an attaching shank 14 adapted for bolting or riveting to the web of the post to which the clamp is attached; an arm 15 extending upwardly beyond the top end of the post and having an inturned head 16 for engagin the girder and for projecting between t e flanges of the girder when the latter is of channel or I-beam construction, and a boss 17 apertured to pass a tightening bolt 18, whereby the clamp members may be tightened to the girder. One of each pair of clamp members is preferably rigidly attached to its post and the other mounted adjustable on the post, preferably by arrangement of the belts or rivets 19 in slots 20 in the web of the post.

The head portions 16 of the respective clamp members are preferably provided with shanks 21 of angle iron construction, one flange of each of which is welded or otherwise secured to the head portion and the-other en aged with the web of the girder to provide an extended contact for stabilizing the clamp member on the girder.

22 designates tie rods extended'through the head portions of the respective clam members and attached thereto by nuts on t e rods which bear against the head portions to retain and stabilize the posts in their spaced relation.

23 designates bearing members set in aligning apertures on the respective posts for seating the shaft 24 of a calf wheel or the like 25.

In employing my invention, the derrick parts are fabricated at the mill in accordance with ordinary practice, and when the derrick skeleton has been erected the posts are applied in proper relation to the well hole so that the cable may be properly reeled onto and from the calf wheel.

It is apparent that after the location of the posts has been determined they may be set on the floor in proper spaced relation and anchored to the floor by the tie plates. After the posts have been anchored to the floor, the clamp members are applied to the girder and tightened to grip the girder firmly therebetween; the spaced relation of the posts being determined and retained by the tie rods on the fixed clamp members. With my improvement, the posts may be set at the same inclination as the derrick and in proper relation to the well hole so that the cable or wire line may be operated to the best advantage and, when set, will be retained in position by the attaching members heretofore described. Should it be necessary, however, to adjust the posts, the upper ends may be easily and quickly loosened from the girder, the posts adjusted and then reclamped on the irder.

g It is also apparent that the posts may be easily and quickly removed from the derrick when the derrick is to be removed from the well.

What I claim and desire to secure by Letters Patent is:

1. In combination with a derrick includ- 7 ing a fioor and cross girder, spaced posts resting on the floor, anchor plates attached to the posts and to the floor sill, clamp mem supported on and attached to the floor, a pair of clamp members on the upper end of each post, one having fixed and the other ad Lustable mounting on the post, an adjusting olt connecting the clamp members, and a tie rod connecting the fixed clamp members on respective posts for retaining the posts in spaced relation.

6. In combination with a derrick including a floor and cross girder, posts mounted on the floor, and paired clamp-members on the posts having inturned heads engaging the girder, one of the clamp members of each pair being fixed and the other movable, and means for drawing the movable members toward the fixed members to clamp the girder therebetween.

7. In combination with a derrick including a floor and cross girder, spaced posts supported on and attached to the floor, a pair of clamp members on the upper end of each post, one having fixed and the other adjustable mounting on the post, an adjusting bolt connecting the clamp members, and tie rods respectively connecting the fixed clamp members and the movable clamp members on respective posts posts in spaced relation.

In testimony whereof I affix my signature.

2. In combination with a derrick including a floor and cross girder, spaced posts supported on and attached to the floor, fixed and adjustable clamp members paired on each post and engageable with the girder, and means for clamping the clamp members to the girder.

3. In combination with a derrick including a floor and cross girder, spaced posts supported on and attached to the floor, relatively fixed and adjustable clamp members on each post, and means on paired clamp members for tightening said members against the irdera 4.
