ABSTRACT:
An improved drive rod and clutch disk for a paint brush and roller cleaning tool providing the unique combination of a hardened steel clutch disk and chrome plated drive rod. Hardening virtually eliminates enlargement of the bow tie hole in the clutch disk due to wear, preventing the cross member on the end portion of the drive rod from escaping through the clutch disk bow-tie hole during the lifetime of the cleaning tool. The chrome plated spiral drive rod minimizes galling, greatly extending the useful life of the cleaning tool in the instant invention, compared to the prior art.
