UNITED STATES PATENT OFFICE.
BENJAMIN IWIASSETH AND DAVID W. BLACK, OF BUTLER, PENNSYLVANIA.
SUCKER-ROD SOCKET.
SPECIFICATION forming part of Letters Patent No. 578,344, dated March 9, 1897.
Application filed May 2, 1896. Serial No. 589,983. (No model.)
To all whom, it may concern.-
Be it known that we, BENJAMIN MASSETH and DAVID NV. BLACK, of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Sucker-Rod Sockets, of which the following is a full, clear, and exact'description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation of our improved socket. Fig. 2 is a partial longitudinal section of the same on a larger scale. Fig. 3 is a side elevation, partly broken away, to show the spring-jaw; and Fig. 4 is a cross-section on the line IV IV of Fig. 2.
Our invention relates to the sucker-rod sockets which are used in deep wells of small diameter, such as those in which a two-inch casing is employed. In sockets for such use it has been found extremely diflicult, if not impossible, to get sufficient thickness of metal in the hollow tube forming the body of the socket to allow the requisite securing of the jaw or jaws in place, while at the same time allowing sufficient internal diameter inside the jaws to allow entry df the suckerrod therein. This difficulty has been entirely overcome by our invention, which consists in providing a tube having an eccentrically-placed hole therein, thus giving on one side of the tube sufficient thickness for placing and suitably securing the jaw in position.
We will now describe our invention as ap-v plied to a socket of the general type shown and described in our former patent, No. 535,709,
. granted March 12, 1895, though we do not wish to be understood as in any wise limiting our invention to such type.
As shown in Figs. 2 and l, we form a tube 2 with an eccentric hole therethrough, one side 3 of the tube thus being thickened sufficiently for the attachment of the spring-j aw 4. This jaw 4 is formed with a shank-piece 5, having V-shaped edges arranged to fit within grooves at the side of a longitudinal slot in the thicker side of the tube, and at its lower end is provided with a head or gripper 6, having inner upwardly-inclined teeth to bite upon the sucker-rod. The slot in the tube is enlarged at its upper end, as shown, to allow entrance of the shank to the guiding-grooves, after which a stop-block 7 is secured in the enlarged portion, thus preventing the upward sliding of the jaw beyond the normal position shown. The slot is also enlarged at its lower end sufficiently so that when the stop-block is removed and the jaw moved upwardly the head will spring out through this enlargement and release the sucker-rod. The tube is provided at its upper end with the usual screwplug and at its lower end is rounded or beveled outwardly to allow easy entrance of the rod.
The advantages of our invention will be apparent to those skilled in the art, since a tool is provided which can be advantageously used in small holes, the jaw being easily and securely fastened in the tool and also detached from the rod without diffioulty.
Modifications in the form, construction, and arrangement of the parts of the device may be made by the skilled mechanic without departure from our invention, since What we claim is 1. A sucker-rod socket consisting of a tube having an eccentric hole therein, and a jaw secured in the thicker portion of the tubewall, substantially as described.
2. A sucker-rod socket consisting of a tube having an eccentric hole therein, and a sliding jaw secured in the thicker portion of the tube-wall, substantially as described. 3. A sucker-rod socket consisting of a tube having an eccentric hole therein, a slot in the thicker side of the tube, and a sliding springjaw movable within said slot, substantially as described.
In testimony whereof we have hereunto set Witnesses:
ALEX. MITCHELL, ANDREW G. WILLIAMS.
