EDWARD R. DONAHUE, HANS J. ANDERSON, AND HARRY B. GREGG, OF BRADFORD, PENNSYLVANIA.
PULL-LINE COUPLING.
Specification of Letters Patent.
Application led May 9, 1911.
Patented Apr. 2, 1912.
serial No. 626,050.
To all whom it may concern:
Be it known that we, EDWARD R. DONA- HUE, HANS J. ANDERSON, and HARRY B. GREGG, citizens of the United States, residing at 62 East Corydon street, Bradford, Pennsylvania, have invented certain new and useful Improvements in Pull-Line Couplings, of which the following is a specification.
Our present invention relates to improvements in pull line couplings, designed for use in connection with apparatus for pumping oil wells by power when a line of sucker rods is used extending from one well to another.
Among the objects of the present invention are to provide a coupling for connecting such sucker rods which shall be simple and durable in construction, capable of being quickly and easily applied, which will be incapable of slipping on the rods, tending in fact to tighten under the Strain, and which may be very economically manufactured.
The invention includes the novel `features of construction and arrangement and combination of parts hereinafter described and Copies of this patent may be obtained for particularly set forth in the appended claim.
A coupling constructed in accordance with my invention is illustrated in the accompanying drawing, in which:
Figure l is a side elevation partly in section, and Fig. 2 is a section on line 2--2 of Fig. 1.
Referring by reference characters to this drawing, the body of the couplingis shown at l, which may conveniently be made of cast metal with an interior tubular bore or opening to receive the adjoining ends of the pull or sucker rods 2 2. At one side the body is provided with alining keyways 3 3 having reversely inclined bottom walls ft 4 and within which keyways are itted tapered keys 5. These keys are provided on the faces which bear against the Sucker rods with suitable notches 6 which serve to increase the gripping effect, and they are also provided with projections or lugs which extend into an opening 7 in the wall of the coupling sleeve or body to enable the keys to be retracted by the use of a suitable tool when the pull rods are to be disconnected from the coupling. A transverse passage or keyway 8 is provided in line with the hads of the keys, into which passage is inserted a wedge for forcing the keys in opposite directions to cause them to grip the ends of the rods. A suspending ring or eye 9 is provided at one side of the coupling by which the line of sucker rods may be suspended.
Having thus what we claim is:
A sucker or pull rod coupling comprising an integral body having a tubular passage for the reception of the ends of the sucker rods, and oppositely disposed tapered keyways, tapered keys slidably held in said keyways, said body having a transverse keyway in line with said keys, and a wedge in said transverse keyway between the heads of the keys.
In testimony whereof, we aflix our signatures in presence of two Witnesses.
