摘要： A surface cleaning machine includes a frame, wheels for supporting the frame and a debris hopper positioned on the forward part of the frame. There is a cylindrical sweeping brush mounted on the frame for rotation about an axis transverse to machine movement. There is a drive on the frame for the sweeping brush with the sweeping brush being mounted behind the debris hopper and rotating in a direction to throw debris from a surface being cleaned forwardly toward the debris hopper. A cylindrical conveying brush, parallel to the sweeping brush, is mounted on the frame for rotation in the same direction as the sweeping brush. The same drive rotates both brushes. The conveying brush is positioned above the sweeping brush and located relative thereto to convey debris moved upwardly by the sweeping brush in an upward and forward direction toward the debris hopper. A scroll is mounted on the frame forward of both brushes and between the brushes and the debris hopper to direct the flow of debris from the brushes to the debris hopper.

摘要： A convertible sweeper (10) has a main rotating cylindrical brush (24) and a second rotatable cylindrical tool (38). The second tool (38) is movable between a first position in front of the main brush (10) where it rotates to assist in very effectively loading debris comprised mainly of dry leaves, paper, etc. into the hopper (68), and a second position in the upper part of the hopper entrance. There it may be held stationary when the debris to be swept is mainly sand, which is very efficiently swept by the main brush (10) alone, or it may be rotated if the debris also includes some light material, because such rotation assists to a degree in loading that material.

摘要： A sweeper (10) movable over a surface (14) to be swept includes a frame (12) having a longitudinal axis parallel to the direction of sweeper movement and a debris hopper (68) mounted on a front portion of the frame (12). There is an opening in the rear of the debris hopper (68) to admit debris. A first brush (24) rotates about an axis transverse to the longitudinal axis of the frame (12) and is located behind the debris hopper (68) and has a motor (25) for rotating the brush (24) to throw surface debris forward into the hopper (68). There is a second brush (38) which is also rotatable on an axis transverse to the longitudinal axis of the frame (12), with the second brush (38) being positioned away from the surface (14) to be swept and in front of the first brush (24). There is an auxiliary sweeping lip (76) positioned closely adjacent to the second brush (38), which lip (76) and the second brush (38) add momentum to debris swept by the main brush (24) into the hopper (68), so that the hopper is more fully loaded. The improvement is especially notable when sweeping light debris such as crumpled paper, leaves, etc.

摘要： A sweeping machine for picking up debris from a surface includes a frame (112) and wheels (116) attached to said frame to support the frame of the sweeping machine over the surface being swept. A cylindrical brush (124) is rotatably attached to said frame. The cylindrical brush includes a tubular main body (200) and tufts (210) attached to said tube such that the tufts extend radially outward from said tube. The tube has regions devoid of tufts (230) bounded by regions (220) having tufts. The sweeping machine also includes a mechanism for rotating said cylindrical brush.

摘要： A sweeping machine (10) has a wheel (12,14) supported body and a rotatable brush (16) mounted transversely of the direction of machine movement. There is a debris hopper (20) adjacent the brush and a dust collection chamber (24) on the body. A vacuum fan (30) draws dust laden air from the area about the brush (16), through the debris hopper (20), and into the dust collection chamber (24). The improvement comprises a dust control side skirt assembly mounted on each side of the body generally in alignment with the brush (16). Each such assembly includes a flexible inner skirt (54) and a flexible outer skirt (52) spaced from the inner skirt. A flexible spacer (60,62) extends between and is attached to the inner and outer skirts, with the spacer and skirts defining a cavity (70) which has an air opening (72) at a lower portion of the side skirt assembly. The air opening is formed by a discontinuity in the spacer. There is an opening (74) in the inner skirt connecting the cavity (70) with the area about the brush whereby the vacuum fan (30) creates an airflow path through the air opening (72), into the cavity (70), through the inner skirt opening (74) and into the debris hopper and dust collection chamber.

摘要： A collectorless vacuum fan for floor maintenance machines has a backplate with an inlet plate attached thereto in spaced relationship, and an impeller between the backplate and inlet plate. Both the backplate and the inlet plate extend radially beyond the periphery of the impeller. A shaft mounts the impeller for rotation. The inlet plate has a central opening providing air to the hub of the impeller. Vanes on the impeller discharge air out through a diffuser channel defined by the space between the inlet plate and the backplate outside the periphery of the impeller. Attachment elements for mounting the inlet plate on the backplate leave the diffuser channel substantially unobstructed so that air is discharged about the entire periphery of the impeller. The fan has increased air flow compared to a conventional fan having an integral collector housing and decreased noise compared to a fan having a 360 degree discharge and no diffuser.
