Abstract A reversible sponge rubber brush, mop or duster which includes a resiliently compressible rectangular block of a synthetic or sponge rubber having rectangular side portions and opposite end portions of a substantially square section with the length of the sponge rubber block being substantially greater than the width thereof, and in which rectangular block there may be provided peripherally extending slots which effectively divide the block into four rectangularly shaped sponge rubber portions which are interconnected within the block by an inner resilient web portion of the block located inwardly of the opposite end and side portions of the block and effectively defined by the slots extending peripherally of the side and end portions of the block. The peripheral slots in the resilient block are so arranged that a wire form or loop of a rigid material provides a holder for the resilient sponge rubber block. The wire loop may be selectively recieved in the slots extending peripherally in the sides and end portions of the block to present for use a work surface of one or another of the rectangularly shaped resilient sponge rubber portions of the sponge rubber block. Thus, there is provided a reversible sponge rubber brush, mop or duster including rectangular portions providing four working sides or surfaces, each of which may be selectively exposed to a surface to be cleaned.
In a device of a type including a resilient rectangular sponge rubber block, and rigid holder means including a rigid wire loop secured to a handle; the improvement comprising the resilient rectangular sponge rubber block including opposite end portions, each end portion having a substantially square end section, and said block including opposite side portions, each of said side portions having a substantially rectangular side section, the resilient block including a pair of peripherally extending slots, one of the slots of said pair of slots extending in each of the opposite side portions of the block, and said pair of slots extending into the end portions of said block and intersecting in a substantially right angular relation at the opposite end portions of the block of said substantially square section so as to effectively divide the block into four rectangularly shaped substantially square ended sponge rubber portions interconnected within the block by an inner resilient web portion, the rigid wire loop of the holder means being adapted to be selectively received in each of said peripheral slots extending in the side and end portions of the block and positioned about the inner resilient web portion interconnecting with the block the four rectangularly shaped sponge rubber portions of the block so that a work surface of one of said four rectangularly shaped sponge rubber portions may be selectively positioned into an operative relation.

The combination defined by claim 1 in which said holder means includes a rigid wire loop adapted to be selectively received in each of said peripheral slots extenDing in the side and end portions of the block and positioned about the inner resilient web portion interconnecting within the block the four rectangular shaped sponge rubber portions of the block so that the work surface of one of said four rectangularly shaped rubber portions may be selectively positioned into an operative relation, the rigid wire loop including securing means extending from one side portion of the block through the peripherally extending slot in which said rigid wire loop has been selectively received and at a position substantially intermediate the opposite end portions of said block, the handle being operatively connected to the securing means of said rigid wire loop, and the pair of peripherally extending slots effectively separating the selected one rectangularly shaped sponge rubber portion from other of said rectangularly shaped sponge rubber portions, said other sponge rubber portions extending adjacent and along sides of the selected rectangularly shaped sponge rubber portion, and the selected sponge rubber portion being permitted by said peripherally extending slots to flex at the inner interconnecting resilient web portion relative to said other sponge rubber portions upon the work surface of the selected sponge rubber portion being operatively utilized.
