SUCKER-ROD ELEVATOR.
Specification of Letters Patent.
Patented Dec. 25, 1906.
Application filed May 23,1906. Serial No. 319,038-
To all whom, it may concern.-
Be it known that I, JOHN A. STooPs, of Fenelton, Butler county, Pennsylvania, have invented a new and useful Sucker-Rod Elevator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whioh- Figure 1 is a perspective view of a suckerrod elevator embodying my invention. Fi 2 is an elevation of a portion of the same with the parts in position to be used as a wrench. Fig. 3 is a section on the line III III of Fig. 2, and Fig. 4 is a fragmentary view showing a modification.
My invention has relation to elevators for suckerrods, and is designed to provide simple means for preventing the guard-finger which holds the sucker-rod in the hook from being broken by the strains brought to bear upon it by the operation of the elevator, especially when the latter is used as a wrench for screwing and unscrewing the sucker-rods from the blocks; and my invention consists in the novel construction, arrangement, and combination of parts, all substantially as hereinafter described, and pointed out in the appended claims.
In the drawings the numeral 2 designates the shank or stem of the device, which is provided at its upper end with the usual swivel 3 and which is forked at its lower end to receive the pivoted hook 4, having the jaw 5 for engagement with the flange or collar of the sucker-rod, as indicated in dotted lines in Fig. 1. 6 designates a guard-finger for preventing the disengagement of the rod by the hook. Formed on the back edge of the hook is a stop projection 7, which when the hook is moved into the positionshown in Fig. 2 is designed to en age the inner wall of a recess 8, formed in the forked end of the shank or stem. This engagement forms a positive stop for the hook when the device is used as a wrench for screwing and unscrewing the sucker-rods, thus entirely relieving the guardfinger 6 from all strains. Heretofore in the use of devices of this kind great difficulty has been experienced by reason of the breaking of these guard-fingers by reason of the strains thrown upon them, and it has been necessary to make them very heavy for this purpose. By the provision-0f the projection 7 and recess 8 the guard-finger is relieved entirely of its stop function and ma be made of a thin light piece, as shown. nstead of using the depending guard-finger 6 I may use a finger 10, extending inwardly from one-of the forks or jaws of the head, as shown in Fig. 4.
What I claim is 1. A suckerrod elevator having a head, a hook pivoted therein,,and a fixed guard-finger secured to one side of the head and arranged to prevent the disengagement of the hook from the sucker-rod, said hook having a stop projection at its closed edge arranged to engage the head on the opposite side thereof from the guard-finger, and thereby hold the hook out of engagement with the guardfinger; substantially as described.
2. A suckerrod elevator having a forked head and a hook pivoted within the fork, said hook and head having interfitting stop portions substantially as described.
3. A sucker-rod elevator having aforked head provided with a guard-finger, a hook pivoted within the fork of the head, and in terfitting stop projections on the hook and head arranged to prevent pressure upon the hook of the guard-finger; substantially as described.
4. A sucker-rod elevator having a forked head provided with a recess, and a hook pivoted within the fork of the head and having a projection arranged to enter the recess; substantially as described.
In testimony whereof I have hereunto set my hand.
