PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Removing and Collecting Dust and
the like from Floors and other Surfaces.
I, CILARLES JAMES HARVEY, of The Grove, Kidderminster, in the County of
Worcester, do hereby declare the nature of this invention to be as follows:-
According to this invention flaps of leather, indiarubber or other suitable material
are fixed radially to two parallel shafts which are driven in opposite directions
the flaps overlapping each other when they are in the same plane as the shafts.
Preferably the shafts carry pairs of friction rollers in contact with each other,
one pair running on the ground and driving the other pair.
One or it might be both sets of flaps act as brushes sweeping the dirt into space
between the rollers and lifting it, the overlapping of the flaps preventing it from
falling down again. Means are provided for delivering the dirt so lifted into a
receiver.
Improvements in Apparatus for Removing and Collecting Dust and
the like from Floors and other Surfaces.
I, CHARLES JAMES HARVEY, of The Grove, Kidderminster, in the County of
Worcester, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
According to this invention flaps of leather, indiarubber or other suitable material
are fixed radially to two parallel shafts which are driven in opposite directions
the flaps overlapping each other when they are in the same plane as the shafts.
Preferably the shafts carry pairs of friction rollers in contact with each other,
one pair running on the ground and driving the other pair.
One or it might be both sets of flaps act as brushes sweeping the dirt into space
between the rollers and lifting it, the overlapping of the flaps preventing it from
falling down again. Means may be provided for delivering the dirt so lifted into a
receiver.
Figure 1 is a longitudinal vertical section of an apparatus constructed according
to this invention. Figure 2 is a vertical section on the line 2-2 Figure 1.
Figure 3 is a plan of the shafts and rollers detached from the case. Figure 4 is
a longitudinal vertical section of a modification.
a a are shafts having friction rollers 66 and 61 61 at their ends. The rollers b

page_text: run on the ground and the rollers 6¹ run in contact with them. c are flexible flaps
fixed to the shafts a. d is a casing provided with doors d¹ and internal guards .
e is
a handle.
In Figure 4 the flaps c instead of being fixed to the shafts a are carried by endless
bands passing around them and also around another pair of rollers g. This
arrangement allows the guards d2 to be made higher so that more dirt can be
collected before it becomes necessary to empty the apparatus.
Or a single such endless band may be employed working in conjunction with
flaps fixed to a roller.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The combination of two sets of moving flaps substantially as described.
2. The combination of a pair of rotating shafts, and flexible flaps rotating with
the shafts, such flaps being so arranged as to overlap each other and to move over
the surface to be cleaned substantially as described.
3. Apparatus for removing and collecting dust and the like from floors and other
surfaces substantially as described.
Dated this on day of December 1831.
