Patent ID: 11828123

Abstract:
An anchor preserves the seal on an oscillating polishing rod in a pumpjack. The anchor has first and second sidewalls. The sidewalls are joined and oriented in opposite directions to create a cylindrical sidewall for the anchor. The cylindrical sidewall extends about a longitudinal axis and is coupled to a radial hinge that is substantially parallel to the longitudinal axis. The radial hinge couples the first sidewall relative to the second sidewall and facilitates the opening and closing of the cylindrical sidewall to create a clamping area in the locked position. A transverse hinge extends in an orthogonal direction relative to the radial hinge. The transverse hinge supports a rotating shaft on the exterior surface of the sidewall. A clasp on the opposite end of the shaft selectively and optionally locks the first sidewall relative to the second sidewall to create the clamping area of the anchor.
