ABSTRACT:
A shop towel is wrapped around a retainer having a base with a ratchet bar extending upwardly from one surface of the retainer base. The ratchet bar extends into a recess of a handle of a body portion having a contoured surface for receiving at one end the retainer and at the opposite end the hand of an operator. The ratchet bar is advanced into engagement with a spring actuated-pawl that extends transversely through the handle body portion. The pawl is axially movable in the handle and maintained by a spring in engagement with the ratchet bar. The ratchet bar is freely advanced into the recess and engaged by the pawl to maintain the retainer movably connected to the handle body portion. The engagement of the pawl with the ratchet bar prevents the retainer from being inadvertently disconnected from the handle until the pawl is pulled by a lever out of contact with the ratchet bar. The retainer is advanced into the handle body portion without requiring rotation of the retainer or the use of tools to frictionally engage the shop towel between the retainer and handle body portion. The retainer has an expanded surface area to shield the operator's hand from contact with the shop towel. The handheld device with the attached shop towel containing a cleaning solution is traversed back and forth the length of a rotating press cylinder to apply the cleaning solution to the surface of the cylinder rotating at a controlled speed. Following the cleaning operation, the shop towel is replaced with a dry towel which is securely clamped in place on the retainer to dry the cylinder.
