(NoHodeL) l F. E. BOYLAN. BLBVATQR FOR SUGKER RODS.
Patented July 25, 1893.
UNITED STATES PATENT OFFICE.
FREDERICK E. BOYLAN, OF CYCLONE, PENNSYLVANIA.
ELEVATOR FOR SUCKER-RODS.
SPECIFICATION forming part of Letters Patent No. 502,169, dated. July 25, 1893.
Application filed March 6, 1893. Serial No. 464.787. (No model.)
To all whom it may concern.-
Be it known that I, FREDERICK E. BOYLAN, a citizen of the United States, residing at Cyclone, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Elevators for Sucker- Rods, of which the following is a specification.
In the elevators generally used a bayonet is welded to the handle of the elevator to keep the sucker-rod pin from escaping from the wrench-head, and oftentimes in making the weld, the prongs of the handle are burned, which renders the use of the elevator dangerous owing to its liability to break during ordinary usage.
The object of my invention is to overcome this objection and to provide a simple and efficient elevator that will be strong and durable for use in raising and lowering sucker-rods in oil and Artesian well tubing, and I accomplish my object by the mechanism illustrated in the accompanying drawings in which Figure 1 is a side elevation of the elevator, and showing a sucker-rod pin supported thereby. Fig. 2 is a top View of the elevator taken on the line w0c Fig. 1. Fig. 3 is a top view of the wrench-head with the handle thrown back and Fig. 4 is an end view thereof.
Referring to the drawings:A represents the handle, provided at its upper end with the swivel-eye B, and at-its lower end with the prongs O, D, and which forms a bail for the wrench-head E. The prongs C, D, are provided with the inwardly extending ears F, G, which are either fixedly secured to or formed integral with the said prongs. The wrenchhead E, is provided with the trnnnions H, which have their bearings in eyes formed in the prongs O, D, and constructed with the recess J for the reception of the shank K of the sucker-rod pin, L.
The dotted circle M, shown in Figs. 2 and 3, indicates the position of the collar N of the pin L on the face of the wrench-head when it is inserted in the recess J, which insertion is permitted by the handle A being thrown back and the openingJ freed from the ear G. But on raising the handle A to the position shown in Fig. 1, the ear G is brought directly over the opening J as shown in Fig. 2, and prevents the escape of the sucker-rod from the wrench-head.
It will be seen from the dotted lines YY which is drawn through the axis of the wrenchhead, Fig. 3, that the center 0 of the pin will be outside of that line consequently throwing the larger part of the weight of the suckerrod on the part P of the wrench-head. To counterbalance this weight the ear F when the handle is in its perpendicular position bears upon the portion Q of the wrench-head, thus holding it in a horizontal position and avoiding any danger there might be in the tilting of the wrench head E.
It is obvious from the above construction that my improved elevator may be used as a wrench, so as to readily screw and unscrew the sucker-rods from the blocks. This is accomplished by using the handle A as a lever after it has been dropped or lowered to the position shown in Fig. 2, and the ears F and G as jaws. Also when the sucker-rod is in the opening J in the wrench-head it is prevented from turning therein while being raised or lowered by the ears F and G which fit against the square faces of the block.
Having thus described my invention, the following is what I claim as new and desire to secure by Letters Patent:
1. In an elevator for sucker rods, the combination with the handle formed at one end with prongs, a wrench-head provided with an opening J pivotally mounted in said prongs, and a pair of inwardly extending ears formed on said prongs, one of said ears being adapted .to fit over the opening in the wrench-head when the elevator is in operative position to prevent the escape of the rod from the opening, and the other adapted to bear upon the wrench-head for holding the same in a horizontal position substantially as shown and described.
2. In an elevator for sucker-rods, the combination with the handle formed at one end with prongs, a wrench-head provided with an opening J pivotally mounted in said prongs, and a pair of inwardly extending ears formed on said prongs, one of said ears being adapted to fit over the opening in the wrench-head when the elevator is in operative position to prevent the escape of the rod from the opening; substantially as shown and described.
FREDERICK E. BOYLAN.
