PROVISIONAL SPECIFICATION.
Improvements in Floor Scrubbing and Carpet Cleaning Machines.
I, JOHAN FREDRIK ENGLUND of Koppungen, Svanskog, Sweden, Farmer, do
hereby declare the nature of this invention to be as follows:
To the one end of the framing of the machine is pivoted a box for receiving the
dirty soap suds. This box is on the side opposite to its open side provided with a
flat scrubbing brush or the like, according to the work for which the machine is to
be used. To the box is fixed a handle which serves to push or pull the machine
along by. Above the box and brush and by preference fixed to the handle is a box
containing the hot soap suds or the rinsing water, and provided with means for
adjusting the outlet therefrom. To the other end of the framing of the machine
is pivoted a framing wherein is pivoted a cylindrical rotary brush or roller.
Around the latter and around a roller mounted on the box for the dirty soap suds
is wrapped a detachable endless band of felt or the like absorbent material; this
band passes over a cross bar or edge against which the dirty water which is mopped
up by the band is wrung out and conveyed into the dirty soap suds box.
The
The pivoted framing containing the rotary brush has an upstanding post which
by a peg or other means can be fixedly connected to the aforesaid handle to either
of two positions or arrangements of the machine. In one position the flat brush is
against the floor and the rotary brush with its band raised clear of the floor.
machine is when thus arranged pushed backwards and forwards to scrub the floor,
the soap suds being supplied in the required quantity from the box containing the
same. Clean rinsing water is then supplied to the box instead of soap suds which
are run off into a box or.pail. The handle is then detached from the aforesaid post
and brought into the other position and there attached to the post. In this
position or arrangement of the machine the flat brush is turned up clear of the
floor and the handle inclined in the opposite direction, so that the rotary brush with
its band comes against the floor. When thus moving the machine in one direction
the water is mopped up by the band and when moving it in the opposite direction
the band is wrung off against the aforesaid edge. Then the floor is or may be
mopped quite dry by taking off the band and putting on another dry endless
band.
A rotary brush is preferred to a mere roller because the absorbent band is
thereby depressed better into any uneven parts of the floor.
The two boxes may be made in one.

1, JOHAN FREDRIK ENGLUND, of Koppungen, Svanskog, Sweden, Farmer, do
hereby declare the nature of this invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement:-
Fig. 1 is a perspective view of a machine constructed according to this invention
and in the form adapted for floor scrubbing, and Fig. 2 is a perspective view of
the same machine in another form, that is to say, adapted to mop up the dirty soap
suds after the floor has been scrubbed.
To the one end of the framing of the machine is pivoted a box A for receiving
the dirty soap suds. This box is on the underside or opposite to its open upper
side provided with a flat scrubbing brush B or the like, according to the work for
which the machine is to be used. To the box A is fixed a handle C which serves
to push or pull the machine along by. Above the box and brush and by preference
as shown fixed to the handle is a box D containing the hot soap suds or the
rinsing water. It is provided with means for adjusting the outlet therefrom.
This means may as shown be a long cock E with a row of through holes or
notches communicating in one position with the interior of the box D. To the
other end of the framing of the machine is pivoted a frame F wherein is pivoted
a cylindrical rotary brush G or elastic roller. Around the latter and around a
roller H mounted with its gudgeons H¹ in lugs A¹ on the box A for the dirty soap
suds is wrapped a detachable endless band I of felt or the like absorbent material;
this band passes over a cross bar or edge K against which the dirty water which is
mopped up by the band is wrung out and conveyed into the dirty soap suds box A.
The rotary brush G has a boss P against which acts a cam with spring N in
such manner that when the machine in the form Fig. 2 is pulled backwards (or in
the direction of the arrow shewn in Fig. 4 presently to be described) the brush at
once in turning round to the left is stopped because the cam O by contact with the
boss P is turned to the left and jambs the brush. When the machine is then
pushed forward the brush is turned to the right while freeing itself from the
cam O, and a portion of the wet band I is squeezed or wrung out against the edge
of the bar K. The pivoted framing F containing the rotary brush has an
upstanding post L which by a peg M or other means can be fixedly connected to
the handle C to either of the two positions or arrangements shown in Fig. 1 or
Fig 2 of the machine. In one position, Fig. 1, the flat brush B is against the
floor and the rotary brush G with its band I raised clear of the floor. The
machine is when thus arranged pushed backwards and forwards to scrub the floor,
the soap suds being supplied in the required quantity from the box D containing
the same, the tap E being set accordingly. Clean rinsing water is then supplied
to the box, the tap E having been first closed. The handle C is then detached
from the post M and brought into the other position and there attached to the
post M, see Fig. 2. In this position or arrangement of the machine the flat
brush B is turned up clear of the floor, and the handle inclined in the opposite
direction, so that the rotary brush G with its band 1 comes against the floor.
When then moving the machine in one direction the water is mopped up by the
band, and when moving it in the opposite direction the band is wrung off against
the aforesaid edge K and run into the box A. Then the floor is or may be mopped
quite dry by taking off the band I and putting on another, dry, endless band.
A rotary brush is preferred to an elastic roller because the absorbent band is
thereby depressed better into any uneven parts of the floor.
The two boxes A and D may as shown on Sheet 2 be made in one. Fig. 3 is a
side view of the machine when used for scrubbing and Fig. 4 a vertical longitudinal

page_text: section and Fig. 5 a plan of the machine when used for mopping up with the band
removed. The same letters being used for the same or corresponding parts in
Sheet 1 it is only necessary to add that the receptacle A for dirty soap suds or
water is in one structure with the box D for hot clean soap suds. The box D has
a cover D' which when swung open allows the box to be filled. Q is a hinged leg

a shield above the apron I for directing the splashed water downwards.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In machines for scrubbing or cleaning plain or carpeted or otherwise covered
floors the application of a rotatory brush or elastic roller in connection with an
endless band or apron, which passes over a cross bar and roller such as K and H
arranged as described.
2. In such machines the application of the rotatory brush in connection with the
endless band or apron for mopping up the scouring or rinsing water or dirt, said
brush being provided with pawl gear so that it can only turn when the machine is
moved in one direction as described.
3. A machine for scouring or cleaning floors consisting mainly of framing
provided with handle for pushing and pulling the machine along, a scouring brush,
with upper open receptacle for the dirty water or dirt, a frame pirotted to the
aforesaid framing and carrying a rotatory brush, an endless band or apron passing
round said brush and round a roller on the framing, a cross bar or edge on the
aforesaid receptacle and means for holding the pivoted frame and rotatory brush
in a raised position free of the floor or in a lower position against the floor, as and
for the purpose described.
4. The construction of machine described with reference to Figs. 1 and 2.
5. The construction of machine described with reference to Figs. 3, 4 and 5.
