  • Patent number: 4275818
    Abstract: A paint brush holder and wiper adapted for easy attachment and detachment from a paint can, roller tray or the like is disclosed. The holder includes a base, a holder disposed within the base for attaching the handle of a brush thereto, a pair of spaced apart side plates each fixedly attached to side edges of the base and having a leg adapted for supporting the holder against the outside surface of a paint can or the like and a finger disposed in a spaced apart relationship with the leg adapted for engaging a rim of a paint can or the like. The fingers and the legs cooperate to securely attach the holder to the can.
