Abstract: This invention pertains to paint brush with bristle clamping panels. The paint brush can be fabricated easily and inexpensively, is easy to use, and provides ready cleaning after use, by releasing the panels and exposing the bristles to the cleaning solution. A paint brush comprising: (a) a paint brush body and handle, the body having formed in one end thereof a cavity for receiving a group of bristles; (b) a pair of pivotal members secured to respective sides of the body, and projecting over the cavity, the pivotal members being capable of abutting bristles when moved to a first closed position, and being remote from such bristles when moved to a second open position; (c) a securing member positioned on the body for securing the pivotal members in a first position and releasing the pivotal members for movement to a second open position.

Abstract: This invention pertains to a paint brush with a replaceable bristle pack. A unitary paint brush with replaceable bristles comprising: (a) a paint brush body and handle, the body having formed in one end thereof opposite the handle a cavity adapted for receiving a group of bristles; (b) at least one releasable member secured to one side of the paint brush body, and projecting over the cavity, the releasable member being capable of abutting the bristles when moved to a first closed position, and being removed from the bristles when moved to a second open position; (c) at least one movable securing member for securing the hinged releasable member in a first position and releasing the hinged releasable member for movement to a second open position; and (d) a group of bristles held together and located within the cavity of the holder, and held in place by the hinged releasable member, said bristle group being removable and secured in place by the releasable mender.

Abstract: This invention pertains to a paint brush bristle clamp which can be removed after paint brush use, and facilitates cleaning of paint from the brush. A removable paint brush bristle clamp comprising: (a) a pair of opposed end walls; (b) a first side wall located between the pair of end walls and joined thereto; (c) a second side wall opposed to the first side wall, the second side wall being joined at one end to one of the end walls, the opposite end of the second side wall being free and having a first lip formed thereon; (d) a second lip formed on one end of one of the end walls, adjacent to the lip formed on one edge of the adjacent side wall, said second lip being adapted to mate with the first lip on the side wall to thereby provide an opening and closing action.

Abstract: The unitary paint brush comprises a paint brush body attached to a handle. The body defines a cavity adapted for receiving a group of bristles inserted therein. A pair of hinged releasable flaps project over the cavity to abut the bristles when moved to a closed position. The bristles are released by moving the flaps into an open position. A pair of springs are urging the flaps into the closed position.
