a carrier frame mounted to said main frame and located below said first and second dirt delivery openings;
first and second dirt containers adapted to be removably positioned on said carrier frame, each container having an upper rim surrounding an associated container inlet opening; and
control linkage carried by said main frame and connected to said carrier frame for moving said carrier frame between a raised use position in which said upper rim of each of said dirt containers engages said casing wall and seals therewith about an associated one of said first and second dirt delivery openings, and a lowered access position in which outer portions of said first and second containers are lowered to an access position, permitting exterior access thereto.

Abstract
A floor-cleaning machine which can be driven over the floor, includes a driven brush for sweeping the floor to be cleaned. The brush picks up dirt and debris from the floor and carries it, assisted by forced air flow, in an overhead motion and through a transfer duct to a pair of dirt containers in the form of buckets located side-by-side at the rear of the machine. A manual linkage at the rear of the machine moves a pivoted carrier frame which holds the dirt containers, between a raised use position in which the upper rims of the dirt containers are sealed to the machine for collection of debris, and a lowered access position for removal of the containers. Each container is independently accessible for emptying, and includes a bail-type handle pivotally attached such that a bucket, the opening of which faces forwardly and upwardly in the use position, extends generally horizontal when removed, to avoid spillage. Each container has a recess adjacent the inlet opening for receiving the handle in the operating position.
