Abstract

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.

Claims Analysis

Total Claims: 25
Claim 1
Independent Claim 122 words
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.
Claim 2
Dependent Claim 122 words
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.
Claim 3
Dependent Claim 25 words
A pump jack pole as claimed in claim 1, further comprising coupling means for connecting said rubberized surface to said one side of said pole.
Claim 4
Dependent Claim 17 words
A pump jack pole as in claim 2, wherein said rubberized surface comprises a rubberized belting material.
Claim 5
Dependent Claim 24 words
A pump jack pole as in claim 1, wherein said coupling material comprises an adhesive material between said rubberized surface and said metal pole.
Claim 6
Dependent Claim 25 words
A pump jack pole as in claim 2, wherein said coupling means further comprises a fastening means interconnecting said rubberized material and said metal pole.
Claim 7
Dependent Claim 56 words
A pump jack pole as in claim 1, wherein each of said pole sections comprise a transverse support pin spaced from the ends thereof, and wherein said splint comprises a metal tube straddling the interconnected pole sections and received within the end portions thereof, and extending between the adjacent support pins of the interconnected pole section.
Claim 8
Dependent Claim 46 words
A pump jack pole as in claim 6, and further comprising fastening means extending transversely through each pole section and the splint contained therein for locking the splint to the pole sections, and wherein said splint is slightly spaced from each of the adjacent support pins.
Claim 9
Dependent Claim 43 words
A pump jack pole as in claim 1, wherein the abutting sections of the rubberized surface are matingly beveled so that the edge of the rubberized surface of one pole section overlies the edge of the rubberized surface of the adjacent pole section.
Claim 10
Dependent Claim 31 words
A pump jack pole as in claim 1, wherein the abutting ends of the rubberized surface are matingly cut along an angle with respect to the elongated axis of the poles.
Claim 11
Dependent Claim 16 words
A pump jack pole as in claim 9, wherein said angled cut forms an inverted V-shape.
Claim 12
Dependent Claim 17 words
A pump jack pole as in claim 1, wherein said metal tubing is formed of aluminum material.
Claim 13
Dependent Claim 16 words
A pump jack pole as in claim 6, wherein said splint is formed of aluminum material.
Claim 14
Dependent Claim 23 words
A pump jack pole as in claim 2, wherein said rubberized belting material comprises a layer of fabric material sandwiched between rubber layers.
Claim 15
Dependent Claim 16 words
A pump jack pole as in claim 13, wherein said fabric material is formed of nylon.
Claim 16
Dependent Claim 127 words
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.
Claim 17
Dependent Claim 127 words
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.
Claim 18
Dependent Claim 19 words
