Abstract
A broom is provided with a rotatable brush head connected to a handle. The brush head and handle each have a longitudinally extending axis located in a common geometric plane. The brush head has a base with a downwardly extending element which, by tongue and groove configuration, engages a separable attachment member which is adapted to receive the handle. A manually operable member with a knob, controls the movement of the attachment element and hence the handle in relation to the brush head, allowing the brush head to rotate to a plurality of angles of alignment with the handle within the common plane. The brush head element, attachment member, and control member are secured together by means of a spring bias system, consisting of an elongated bolt or similar means and a coiled spring. This system secures the attachment member and control member to the brush head in a tightly biased manner, to maintain the brush head in position on the handle. Loosening the attachment member by rotating the control member allows the brush head to rotate to various angles, for instance 10.degree., 45.degree., and 90.degree., to the handle. Tightening the control member fixes the brush head at a gi…
