Abstract
A pump jack upright pole formed of an elongated metal pole having a rubberized surface formed on only one side of the metal pole. The pump jack securely rides up and down the pole. The rubberized surface is longitudinally offset with respect to the pole so that it extends past one end of the pole while exposing the opposing end of the pole. A splint is arranged to be received within adjacent ends of poles being spliced together with the rubberized surface extending end overlying the exposed pole end of the next adjacent section. The rubberized sections are interfitted to provide a continuity so that the pump jacks can ride up and down the poles without interference.
Claims21
A pump jack comprising an elongated metal tubing having a rectangular cross sectional configuration, and a rubberized surface formed on only one side of the tubing, said pole comprising two pole sections, a splint means for interconnecting said two sections at abutting ends thereof, said rubberized surface being longitudinally offset with respect to the pole sections so as to extend a predetermined distance past one end thereof and to expose a corresponding distance of the pole at the other end thereof, and wherein the interconnected ends have the extended rubberized surface of one pole section covering the exposed portion of the adjacent pole section such that the rubberized surfaces abut at a location spaced from the abutting ends of the pole sections.
In combination, a pump jack having upper and lower shackles, a foot pump for operating the shackles to cause the pump to climb up the pole, a crank for operating a roller permitting the pump jack to ride down the pole, and an extended arm on which a platform is positioned whereon workers, equipment and supplies are normally supported;
- and
- a pump jack pole comprising elongated metal tubing having a rectangular cross sectional configuration, a rubberized belting material, and means for securing said belting material onto one exterior side of said tubing facing between the shackles and toward said roller, said rubberized belting material being sufficient in strength to support the heavy weight carried by the pump jack as it climbs up and rises down the pole.
A pump jack pole comprising an elongated metal tubing having a rectangular cross sectional configuration, and a rubberized surface formed on only one side of the tubing, said pole comprising two pole sections, and splint means for interconnecting said two sections at abutting ends thereof, and further comprising laterally spaced apart rivet means coupling said rubberized surface to its respective pole section, and further comprising a metal plate at least a portion of which fits between the laterally spaced apart rivets and coupled to one side of said splint to thereby provide a tight fit of said splint within said pole sections.
A pump jack pole comprising an elongated metal tubing having a rectangular cross sectional configuration, and a rubberized surface formed on only one side of the tubing, said pole comprising two pole sections, and splint means for interconnecting said two sections at abutting ends thereof, and further comprising a splice of rubberized surface interconnecting the rubberized surfaces on each section, whereby the rubberized surfaces abut at a location spaced from the abutting ends of the pole sections.
