Frame-less, Split Pipe Wiper

Abstract

The frame-less, split pipe disclosed herein includes a fixed actuator assembly with carries a blade-like pipe wiper element and a sliding actuator assembly which carries a similar blade-like pipe wiper element. Each of the pipe wiper elements is disposed between a clamp and the base of their respective actuator assemblies. The sliding actuator assembly is disposed in a pair of channels disposed above the claim of the fixed actuator assembly. A pair of pneumatic cylinders, one on each side of the fixed actuator assembly moves the sliding actuator assembly between open and closed positions. For installation, removal or maintenance on a pipe wiper it may be split into two open-throated components by removing the pins which attach the operating rods of the pneumatic cylinders to clevises of the sliding actuator assembly.

1 . A frame-less pipe wiper comprising:
 a fixed actuator assembly having a length which terminates at ends, a width which terminates at sides and is comprised of a clamp having side elements, a base having side elements, a wiper element disposed between said clamp and said base and attached to each side of said base a longitudinal slide assembly having a top portion which is spaced apart from and over-hangs at least a portion of the adjacent side element of said clamp thereby forming a pair of longitudinally disposed channels between each the side elements of said clamp and said top portions of said slide assemblies;   slidably disposed in said pair of channels a sliding actuator assembly having a length which terminates at ends, a width which terminates at sides and is comprised of a clamp having side elements, a base having side elements, a wiper element disposed between said clamp and said base; and,   a pair of air cylinders, the first of which has a body which attached to one of said sides of said fixed actuator assembly and has a rod which is removably attached to adjoining side of the sliding actuator assembly and the second of which has a body which attached to the opposite side of said fixed actuator assembly and has an a rod which is removably attached to adjoining side of the sliding actuator assembly.
