Abstract

A self-propelled industrial cleaning machine has a cylindrical horizontally mounted rotatable cleaning brush. There is a torsionally rigid connecting member extending generally parallel to the brush. A rigid arm is attached to each end of the connecting member, with each arm supporting an end of the brush. There is a hand operable latch for releasing one of the arms to permit removal or replacement of the brush, with the hand operable latch being arranged to retain the one arm and attachment to the connecting member, with release thereof permitting removal of the arm from the connecting member and brush.

Claims

1. In a self-propelled industrial cleaning machine, a cylindrical horizontally mounted rotatable cleaning brush, a torsionally rigid connecting member extending generally parallel to and radially spaced from said brush, a rigid arm attached to each end of said connecting member, with each arm supporting an end of said brush, and a hand-operated latch having a movable keeper for releasing one of said arms to permit removal or replacement of said brush, said hand operable latch being arranged to retain said one of said arms in attachment to said connecting member, with release thereof permitting removal of said one arm from said connecting member and brush.

2. The cleaning machine of claim 1 further characterized in that said hand operable latch includes a strike member mounted on an end of said connecting member, said movable keeper being mounted on said one arm.

3. The cleaning machine of claim 2 further characterized in that said keeper is pivotally mounted on said one arm.

4. The cleaning machine of claim 3 further characterized in that the attachment of said one rigid arm to said connecting member includes a sliding connection therebetween.

5. The cleaning machine of claim 4 further characterized in that the sliding connection includes a plurality of pins extending outwardly from said rigid connecting member, and a plurality of openings in said one rigid arm.

6. The cleaning machine of claim 1 further characterized in that said hand-operated latch is releasable without the use of tools.
