Title: Broom assembly

Abstract: A surface sweeping broom in which the handle is attached to an elongated brush head of circular cross-section. The brush head contains a cylindrical inner core overlaid with a molded thermoplastic brushing surface. The molded brushing surface is comprised of a base or matrix and fingerlike projections which are integrally fused with the matrix and extend vertically from it. In one embodiment, the brush head is provided with a centered bore which extends completely through it. The bore is threaded to secure a handle member which can be inserted at either end of the bore. Thus, when a brushing surface becomes worn, the handle can be reversed. In this manner, all four quadrants of the circular brushing surface can be effectively utilized.
