The invention further includes the use of an inventive cleaning brush apparatus for which allows dirt and dust to be swept into gaps between rows of bristles, which are attached to a handle via metal rails. Accordingly, dust is concurrently collected into a row of suction holes without requiring separate steps to sweep and collect the dust.

Patent number: 5641138Abstract: A trash bag stand comprises a lip ring, a stand fastener, a bag securing mechanism, a drop and a bag dispenser. The bags are disposable and each bag is assumed to have, as typical, a body with a length and a lip defining the opening of the bag into the bag body, the lip having a circumference. The lip ring has a circumference approximately equal to the bag lip circumference and has a length perpendicular to the plane of its circumference substantially shorter than the length of the bag. The stand fastener fastens the ring to substantially any desired support structure. The bag securing mechanism preferably takes the form of a securing ring for securing the bag lip to the lip ring, and is hingedly fastened to the lip ring to remain with the lip ring and also be movable between a position in which the securing means secures the bag lip to the ring, and a position in which the securing means is sufficiently distant from the ring to provide for placement of the bag lip on the ring.Type: GrantFiled: April 21, 1995Date of Patent: June 24, 1997Assignee: The ServiceMaster CompanyInventors: Leon Cronk, Quentin Alverson
