Claim Text:
1. An apparatus to wipe a tubular member, the apparatus comprising: a first wiper section and a second wiper section; a position sensor coupled to at least one of the first wiper section and the second wiper section to detect the position of the at least one of the first wiper section and the second wiper section; a base having a first base section and a second base section, wherein the first wiper section and the second wiper section are removably connected to the first base section and the second base section, respectively, wherein the first wiper section and the second wiper section are parallel to the first base section and the second base section, and wherein the first wiper section and the second wiper section are linearly movable with respect to each other towards a point of convergence; a first actuator, a first coupler link, and a first translating block connected between the first wiper section and the first base section to linearly move the first wiper section between an open and closed position; and a second actuator, a second coupler link, and a second translating block connected between the second wiper section and the second base section to linearly move the second wiper section between an open and closed position, wherein at least one of the first actuator and the second actuator is disposed such that the at least one of the first actuator and the second actuator actuates in a direction that is offset from a direction in which the first wiper section and the second wiper section move linearly with respect to each other, and wherein at least one of the first coupler link and the second coupler link comprises a pivot point about which the at least one of the first coupler link and the second coupler link rotates to convert offset actuation movement of the at least one of the first actuator and the second actuator into linear movement of the first wiper section and the second wiper section with respect to each other.
