Application filed March 4, 1926. serial No. 92,147.
This invention relates to elevators and more particularly to elevators for raising or lowering sucker rods or other work in oil wells, and the general object of the invention is to provide a support for the elevator aws when they are bridging the work-receiving recess of the elevator body to confine the work within said recess, thus preventing the jaws from being bent or broken.
A more particular object'is to provide an elevator of the character stated which may be easily manipulated and readily applied to or disengaged from the work. v
With the above and other objects in view, theinvention consists in the novel and useful provision, formation, combination, association and relative arrangement of parts,
members, and features, all as here'inafterdescribed, shown in'the drawings, and finally pointed out in claims.
- In the drawings:
Figure 1 is a side elevation of the elevator;
Figure 2 is .a transverse vertical section of the elevator taken onithe line 2-2 of Fig. 4:;
Figure 3 is, a transverse vertical section of the elevator taken at right angles to Fig,
. with a vertical cylindrical wall b .and a bottom wall I), on the to of which vertical wall a top late 1 is bolte by bolts 2, there being a wor -'recei'ving recess R in the vertical wall I) and bottom wall b of the body B and in the top plate 1, which recessextends radially from the center of the elevator through the periphery thereof, and the inner end of the recess is struck on-an are from said center. The bottom wall 1; has a' rearward extension .b and the top wall 1 has a rearward extension 1. A circular cam disk D is turnably fitted within the cylindrical 'wall I) of 7 the elevator body B upon the bottom wall 6' of said body, said disk beingprovided with a radial recess '1' extending from its center through its periphery, and there being a handle H on the disk extending outwardly from the periphery thereof through a honzontal slot 6 in the cylindrical wall of the elevator body. A latch L is pivoted at 3 to the outside of the vertical wall b of the body B and is formed with a shoulder 4, for engaging the handle H ,to hold the cam disk D against turning to the right when said disk is swung to its extreme position to the left.
A pair of arcuate jaws J rest upon the cam disk D and are-pivoted at their rearends at the rear end of the recess R on a pivot pin P secured at its upper end in a boss 1 in the top plate l. said jaws being formed respectively with knuckles. 5 at the rear ends which rest one upon the other and through which depends the pivot pin P. In the lower sides of the jaws J are secured cam .pins c which engage cam grooves C in the upper face of the cam disk D. The upper inner edges ofthe jaws J are beveled to form a conical seat S for the hell 8' of a sucker rod 8. Trunnions T project from opposite side of the body B and are engaged by the usual links K through which the elevator is raised or lowered in the usual manner.
The operation of the. elevator is as fol-' lows:
When-the handle His swung to the right.
to the end of the slot 7), the disk D is correspondingly turned until its recess '1' registers with-the work recess R of the elevator body B, while the cam grooves C engage the cam ins c and swing the jaws open as illustrate' 1n Fig. 1. In" this osition of the parts the work such as a suc er rod .9 is introduced into the recess R. The handle H and disk D are then swung to the left until,
that portion of the disk at' the left side of the disk recess 1', indicated 1*, is extended across the work recess R and said portion rests upon the bottom body wall 5 at opposite sides of the work recess, during which opera tion the aws J, by the engagement of cam grooves C with cam pins 0, are swung closed meeting ends of the jaws bridging the recess and resting directly upon the portion 1'" of the disk D, in which position the parts are locked by the engagement of the latch L with the handle H. The seat S of the jaws J engages the balls of the sucker rod s-for raising or lowering. the rod, and the disk portion r supports the bridging ends of the jaws with the weight of the sucker rod around the sucker rod s, with the forward;
on the jaws and prevents breaking or bending ofsaid ends of the jaws downwardly.
The extension 1* and b" prevent the handle H from striking against objects, thus protectin the handle.
It is 0 vious that various changes and across the work-receiving recess and with the bridging ends of the jaws resting upon said extended disk portion.
