the belts are provided with cross-cleats, serrations, or
friction members whereby when the brush 4 engages a
surface to be cleaned, and the unit 2 is moved thereover,
the belts drive the brush member 4.
Since the circumference of the brush drive wheels is
less than the circumference of the brush, the brush mem

over which it is moving. The term “faster than syn

In the drawings, the sweeper and dust pan unit pro
vided by the invention is generally designated by the nu
meral 2.
Such unit includes a brush member generally
designated by the numeral 4; a handle member generally
designated by the numeral 6; support means generally
designated by the numeral 8 for rotatably joining the
rush-supporting frame to the handle member, drive
means, generally designated by the numerals 10 and 10’, 10 used in this description and the appended claims, means

ignated by the numeral 16 pivotally couple the dust pan
by a distance equal to the circumference of the brush

With the preferred construction, the rollers 50 are so

of pan 12 directly behind the brush member as shown in
solid lines in FIGURE 2 when the brush member engages
the surface to be swept, to a position where the dust re

member when the brush member is elevated as shown in
dotted line in FIGURE 2.
The means generally designated by the numeral 16 for
pivotally coupling the dust pan with the support means
dimensioned, and the lugs 34 on which the rollers are
journaled are so positioned, that the belts terminate above
the lower extremity of the brush member, and thus the
brush member must be pushed down whereby the bristles
thereof ?ex before the drive belts contact a surface to
be swept and drive the brush member. This allows for
operation of the device properly even as the bristles wear

The inwardly bent ends 28 and 30 of frame member

parallel to the rotational axis of the brush member and
the brush drive wheels 44. The inwardly bent ends of
shaft lugs 34 extend parallel to the rotational axis of both
the brush member 4 and the brush drive wheels 44, and
terminate in spaced relation to the ends of the brush
member. As shown, the rollers 50 carried on such lugs
are peripherally, and preferably vertically, aligned with
their associated brush drive wheels; that is, rollers 50
are aligned with respective adjacent brush drive wheels

strip 74 which forms a surface-engaging lip. The front
portion of the stepped bottom wall 66 of the pan 12 ex
tends in contiguous parallel relation to and adjacent the
rubber strip 74, and is ?at over a predetermined width.
This ?at portion or area slides over a surface to be swept,
such as, for example, carpet, without sinking thereinto,
and accordingly, the force required to move the pan over
such surface is minimized.
Preferably also provided on
the bottom of the pan are two metal sliders 196 bonded
to sponge rubber pads 198 which in turn are bonded
to the bottom surface of the pan. The metal sliders 196
are contoured to slide among engaging particles of grit

around an associated roller and brush drive wheel, and 75 0r irregularities and the sponge rubber pads 198 and the

of the pan when it is slid over hard surfaces.
The steps 67, 67' in the stepped bottom wall 66 of the
pan 12 serve to retain dust particles previously collected.
Although described above in detail as comprising separate
walls, the dust pan preferably is formed from two molded
plastic sections which are joined together as by cementing

1'16 and 118, such as 120‘ and 122, can engage the bottom
wall 66 of the pan to prevent the pivotal connecting means
from moving too far down, relative to the pan, to apply
