Improvements in Carpet Sweepers.
A communication from abroad by JACOB WARREN ROOP, Physician, and AUGUST
FREDERICK WERNER, Baker, both residing at Harrisburg, in the County of
Dauphin and State of Pennsylvania, one of the United States of America.
I, JOHN CORRY FELL, of the firm of Fell and Wilding, of 1 Queen Victoria
Street, in the City of London, Patent Agents, do hereby declare the nature of this
invention to be as follows:-
:-
My invention is designed to produce a sweeper for general use and to this end
I have improved the construction in many of its details and at the same time
applied features which are broadly new, and which, while being shown in con-
nection with the generally improved sweeper, may be used upon other forms of
sweepers, and independently of the various details shown herein.
Primarily aim to provide means to sweep into the corners, and along the
wash boards of a room, where under ordinary circumstances it is impossible for the
sweeper to reach. A further object is to provide such a construction of supplemental
brush and main brush, the first for reaching places ordinarily inaccessible to the
common form of sweeper, and the latter for doing the ordinary work of sweeping, as
shall be capable of being operated by the handle of the sweeper, one of said brushes
being operated by the movement of the handle in one direction, and the other by
the movement of the handle in the opposite direction. Another object is to improve
the various parts of the sweeper as to the means for driving the brush, and to the
construction of the dust pan, and in the use of a pair of supplemental brushes
arranged to operate at the end of the case which encloses the main brush.
The invention consists in the devices and combination of devices hereinafter
particularly described.
In the accompanying drawings which illustrate my invention,
Fig. 1 is a plan view of my improved sweeper with the handle broken away.
Fig. 2 is a side elevation of the same with the dust pan shown in one position
in dotted lines, and in its normal position partially in full lines and partially in
dotted lines.
Fig. 3 is a front elevation on the left of said figure and a sectional view through
the case on the right of the figure.
Fig. 4 represents a modification of the means for applying pressure to the main
brush.
Figs. 5 and 6 represent the supplemental brush as an attachment to an ordinary
sweeper.
In these drawings the box or case of the sweeper is shown at A, and may be of
the ordinary or any desired construction according to the requirements of the sweeper,
and of course may be of any suitable material. The main brush is enclosed within
this case, and is shown at B. This brush may be of the ordinary construction and
composed of any material suited for the purpose. It is journalled in bearings at
cach end, these bearings consisting of cross bars a, pivoted at 1 to the end of the
box or case, the other end having a certain amount of play in a loop 2, secured to
the end of the case, the said cross bars bridging the openings in each end of the
case, and each are in line with the shaft of the brush. These cross bars may have
pintles projecting inwardly and fitting corresponding recesses in the ends of the
shaft of the brush, or the said shaft may be supported from the said bars in any
other desired manner. The free ends of the bars are held normally up by springs 3,
which may engage with the free ends of the cross bars as shown in Fig. 2, or as

page_text: shown in Fig. 3, these cross bars may be connected, each to the upright extension,
and these extensions connected across the top of the case by a horizontal rod c with
spiral or other suitable springs interposed between said rod and the top of the case,
these springs being indicated in Fig. 3 at d. These springs tend to hold the brush
entirely above the floor, normally, or only slightly in contact therewith. It will
of course be understood that whether the brush be in contact with the surface to be
swept or out of contact therewith depends entirely upon the tension of the springs,
and this tension may be such as to effect the desired purpose. Yielding bearings
are thus provided for the brush, and the brush may be made to bear against the
surface to be swept with more or less pressure as will be hereinafter explained.
The main brush is driven by a sprocket chain which passes around the shaft of the
brush engaging with teeth thereon, through openings in the rear wall of the case,
and from thence around the sprocket wheel e, which is on the shaft f, of the bearing
wheels g.
These wheels and shaft are supported in rear of the case by suitable
brackets h, which are connected to the said case. The wheels are preferably
provided with rubber tyres which in the movement of the sweeper causes sufficient
traction to drive the brush either in one direction or the other, in accordance with
the direction of movement of the said sweeper.
In order to provide for the removal of the dirt from proximity to the wash boards
of the room and the corners and other inaccessible places I arrange a supplemental
brush, preferably outside the case, and slightly in advance of the same, though I do
not desire to limit myself to the location of this brush, as the casing of the sweeper
could very evidently be made to cover it, if this were found desirable. This brush
consists of the head piece i, provided with bristles of any suitable material adapted
to effect the brushing action, the said brush being suspended from a lever k, pivoted
at 4, on the supporting post connected to the upper part of the casing. A spring 5
bears against the under face of the lever k, and tends to keep it pressed constantly
upward, thus holding the supplemental brush normally above the level of the surface
to be swept. I prefer to make the supplemental brush of a width slightly in excess
of that of the box or casing, and have shown in the drawings at 6, a single tuft at
each end of the brushing material, extending beyond the end of the casing, these
tufts being supported from the head of the supplemental brush.
Pivoted near the rear on each side are levers 7, and these levers extend to the
front, having their ends bent at right angles inwardly and engage with elongated
slots in these bent ends with a pin or screw on the head block of the supplemental
brush. These levers support circular brushes C, outside the case, and preferably
extending in line with the single tufts 6, of the supplemental brush, thus extending
the scope of the sweeper and allowing the brushes C to sweep up close to the wash
boards of the room.
The casing is provided with forward wheels 8, which are also provided with
rubber tires preferably, and through these tires the brushes C are rotated, the said
brushes being mounted on spindles which are provided with corrugated discs 9,
resting normally on the peripheries of the forward wheels. The handle yoke is
shown at 10, being pivoted in openings formed in lugs secured to the top of the
casing. This yoke has a central cylindrical opening through which passes the
handle 11. This handle carries upon its exterior lower end a casting 12, which is
held to the squared end of the handle by a set screw. The handle has a swivelling
movement in the circular opening of the yoke, this movement being limited by the
pin 13, which is adapted to have movement between the walls of the recess formed
on the lower edge of the yoke.
Any suitable amount of pressure may be applied to the main brush by the axial
movement of the handle through the projecting finger 14, extending from the
casting 12, which finger, in the axial movements of the handle in one direction,
comes in contact with the cam shaped end of the lever 15, pivoted in a recess in the
top part of the case. This lever has a projection extending from its upper face
across the upper surface of the rode, and thus as the lever 15 is depressed through
the axial movement of the handle to the right the springs d are compressed, and

page_text: pressure applied to the brush. In Fig. 4 a modification is shown of means for
applying pressure to the brush, consisting of a lever 15", pivoted beneath the top of
the case at one end, with its opposite end hent at right angles and extending up
through the opening in the case into line with the finger 14, which is adapted to
operate the same as before described. This lever 15" is held normally up by the
spring 16, and is provided with a pressure roller which bears upon the projecting
teeth on the periphery of the shaft of the main brush, and thus when the handle is
turned as above described pressure is applied directly to the shaft b, and the brush
caused to bear more forcibly upon the surface to be swept.
The lever has a lower extension 1, which is bent slightly to one side so as to
come directly over the curved upper surface of the finger 14, and in the axial
movement of the handle to the left the front end of the lever is depressed,
overcoming the pressure of the spring 5, and the supplemental brush thrust
downward in contact with the floor. Along the top of the head piece of the
supplemental brush is a rod preferably of spring material, this rod extending beyond
the ends of the head piece so as to engage with the outer ends of the lever 7, and
thus as the supplemental brush is brought into contact with the floor the ends of the
spring rod 17 bear with a yielding pressure upon the ends of the lever 7, thus
increasing the frictional contact of the discs of the brush C with the forward
supporting wheels, and causing them to be revolved. It will thus be seen by the
arrangement described that in one movement of the handle pressure may be applied
to the main brush, while in the reverse movement the main brush is released and
the supplemental brush placed under pressure. This action is desirable for the
reason that when it is desired to sweep close to the wall the sweeper is placed
in position with the supplemental brush in contact with the wash board. The
handle is then turned to the left, which brings the supplemental brush in contact
with the floor, while the main brush is out of contact therewith. The sweeper is
then drawn outward from the wall, the supplemental brush drawing the particles
of dirt with it. The handle is then turned in the opposite direction, thus
relieving the supplemental brush and applying pressure to the main brush, and
the sweeper then advanced towards the wall taking up the dirt previously
withdrawn.
The side brushes C enable me to sweep along the sides of the room in close
proximity to the wash boards, and thus the floor may be thoroughly swept along.
the sides to the corners of the room, and the dirt in the corners removed by the
action above described in alternately drawing the dirt out of the corners, and then
advancing the sweeper to take up the dirt thus withdrawn.
The dust pan has been simplified in my present construction of sweeper,
being made in a single piece and pivoted to the front end of the lower edge of the
sweeper with the ordinary opening in the bottom in line with the brush, the rear
end of the dust pan being removably held by catches which engage with the bent
ends of a pivoted rod held normally in engagement with the hooks by a spring.
The pan is shown at D, the hooks at m, and the pivoted rod at n.
It will be understood that while I have shown my improved sweeper made up of
various improved elements, these various improvements may be applied to other
sweepers now in use, either in part or in whole, without departing from the spirit
of my invention.
I do not limit myself to the particular means shown for operating the supple-
mental brush as it is evident that the means shown may be varied in many ways,
and this is true also of the means for driving the main brush and applying pressure
thereto.
When the side wheels C C are dispensed with the supporting wheel or wheels
for the front may be arranged within the casing so as to be concealed.
The brushing tufts may also be dispensed with and the supplemental brush made
wide enough to extend to the line of the side brushes so as to take the place of the
tufts.
The exposed faces of the supplemental brush and side brushes may be covered

page_text: with any suitable material or provided with buffer pads to protect the furniture and
wash boards from becoming scratched in the use of the apparatus.
While have described my improved sweeper in connection with the supple-
mental brush, I desire it to be understood that I may provide the supplemental
brush as an attachment to ordinary sweepers without regard to the general
construction of the sweeper. In Figs. 5 and 6 I show the supplemental brush
as an attachment capable of being readily applied to any form of sweeper with-
out in any way modifying the action of the sweeper except to make it more
effective by adding the function of the supplemental brush. In these figures the
brush is of the same general construction as shown in the other figures. It is
supported upon two leverse, which have slotted ends engaging studs or screws
projecting from the rear face of the stock of the supplemental brush. The
levers are bell cranks and are pivoted at a² to the depending part 2 of a
casting c², which is secured to the casing of the sweeper and serves to support the
supplemental brush and operating parts. The lower ends of the bell cranks
extend downwardly from the pivots and are connected to the limbs of a spring d
the tendency being to throw apart the short arms of the bell cranks lifting the long
arms and thus keeping the brush elevated. In order to depress the brush a cord
connected to the brush or a standard thereon passes over pulleys 23 and through
eyes to the handle, and by pulling on said cord the brush is manipulated. It
will be seen that the necessary connections to attach the brush to an ordinary
sweeper are few in number, simple in construction, and may be applied by unskilled
labour.
Instead of the part 2 being a casting it may be made of sheet metal.

Improvements in Carpet Sweepers.
A. communication from abroad by JACOB WARREN ROOP, Physician, and AUGUST
FREDERICK WERNER, Baker, both residing at Harrisburg, in the County of
Dauphin and State of Pennsylvania, one of the United States of America.
I, JOHN CORRY FELL, of the firm of Fell and Wilding, of 1, Queen Victoria
Street, in the City of London, Patent Agents, do hereby declare the nature of
this invention to be particularly described and ascertained in and by the following
statement :-
My invention is designed to produce a sweeper for general use, and to this end
I have improved the construction in many of its details and at the same time
applied features which are broadly new, and which, while being shown in connection
with the generally improved sweeper, may be used upon other forms of sweepers,
and independently of the various details shown herein."
Primarily I aim to provide means to.sweep into the corners, and along the wash
boards of a room, where under ordinary circumstances it is impossible for the
sweeper to reach. A further object is to provide such a construction of sup-
plemental brush and main brush, the first for reaching places ordinarily inaccessible
to the common form of sweeper, and the latter for doing the ordinary work of
sweeping, as shall be capable of being operated by the handle of the sweeper,
one of the said brushes being operated by the movement of the handle in one
direction, and the other by the movement of the handle in the opposite direction.
Another object is to improve the various parts of the sweeper as to the means for
driving the brush, and to the construction of the dust pan, and in the use of a
pair of supplemental brushes arranged to operate at the end of the case which
encloses the main brush.

page_text: The invention consists in the devices and combination of devices hereinafter
particularly described and claimed.
In the drawings which accompanied my Provisional Specification and illustrated
my invention,
Figure 1 a plan view of my improved sweeper with the handle broken away.
Figure 2 is a side elevation of the same with the dust pan shown in one position
in dotted lines, and in its normal position partially in full lines and partially in
dotted lines.
Figure 3 is a front elevation on the left of said figure and a sectional view
through the case on the right of the figure.
Figure 4 represents a modification of the means for applying pressure to the
main brush.
Figures 5 & 6 represent the supplemental brush as an attachment to an ordinary
sweeper.
In these drawings the box or case of the sweeper is shown at A, and may be of
the ordinary or any desired construction according to the requirements of the
sweeper, and of course may be of any suitable material. The main brush is enclosed
within this case, and is shown at B.
This brush may be of the ordinary construction and composed of any material
suited for the purpose.
It is journalled in bearings at each end, these bearings
consisting of cross bars a, pivotted at I to the end of the box or case, the other end
having a certain amount of play in a loop 2, secured to the end of the case, the
said cross bars bridging the openings in each end of the case and each are in line
with the shaft of the brush. These cross bars may have pintles projecting inwardly
and fitting corresponding recesses in the ends of the shaft of the brush, or the
said shaft may be supported from the said bars in any other desired manner.
The free ends of the bars are held normally up by springs 3, which may engage
with the free ends of the cross bars as shown in Figure 2, or as shown in Figure 3,
these cross bars may be connected, each to the upright extension b, and these
extensions connected across the top of the case by a horizontal rod c with spiral
or other suitable springs interposed between said rod and the top of the case, these
springs being indicated in Figure 3 at d. These springs tend to hold the brush
entirely above the floor, normally, or only slightly in contact therewith.
It will of course be understood that whether the brush be in contact with the
surface to be swept or out of contact therewith depends entirely upon the tension
of the springs, and this tension may be such as to effect the desired purpose.
Yielding bearings are thus provided for the brush, and the brush may be made
to bear against the surface to be swept with more or less pressure as will be
hereinafter explained.
The main brush is driven by a sprocket chain which passes around the shaft
of the brush engaging with teeth thereon, through openings in the rear wall of the
case, and from thence around the sprocket wheel e, which is on the shaft, of the
bearing wheels ; these wheels and shaft are supported in rear of the case by
suitable brackets h, which are connected to the said case.
The wheels are preferably provided with rubber tyres which in the movement
of the sweeper causes sufficient traction to drive the brush either in one direction
or the other, in accordance with the direction of movement of the said sweeper.
In order to provide for the removal of the dirt from proximity to the wash
boards of the room and the corners and other inaccessible places I arrange a
supplemental brush, preferably outside the case, and slightly in advance of the
same, though I do not desire to limit myself to the location of this brush, as the
casing of the sweeper could very evidently be made to cover it, if this were found
desirable.
This brush consists of the head piece i, provided with bristles of any suitable
material adapted to effect the brushing action, the said brush being suspended
from a lever k, pivotted at 4, on the supporting post connected to the upper part
of the casing.

page_text: A spring 5 bears against the under face of the lever k, and tends to keep it pressed
constantly upward, thus holding the supplemental brush normally above the level
of the surface to be swept. I prefer to make the supplemental brush of a width
slightly in excess of that of the box or casing, and have shown in the drawings
at 6, a single tuft at each end of the brushing material, extending beyond the end
of the casing these tufts being supported from the head of the supplemental
brush.
Pivotted near the rear on each side are levers 7, and these levers extend to the
front, having their ends bent at right angles inwardly and engage with elongated
slots in these bent ends with a pin or screw on the head block of the supplemental
brush. These levers support circular brushes C, outside the case, and preferably
extending in line with the single tufts 6, of the supplemental brush, thus extending
the scope of the sweeper and allowing the brushes C to sweep up close to the wash
boards of the room.
The casing is provided with forward wheels 8 which are also provided with
rubber tyres preferably, and through these tires the brushes C are rotated, the said
brushes being mounted on spindles which are provided with corrugated discs 9
resting normally on the peripheries of the forward wheels. The handle yoke is
shown at 10, being pivotted in openings formed in lugs secured to the top of the
casing. This yoke has a central cylindrical opening through which passes the
handle 11. This handle carries upon its exterior lower end a casting 12, which is
held to the squared end of the handle by a set screw. The handle has a swivelling
movement in the circular opening of the yoke, this movement being limited by the
pin 13, which is adapted to have movement between the walls of the recess formed
on the lower edge of the yoke.
Any suitable amount of pressure may be applied to the main brush by the axial
movement of the handle through the projecting finger 14, extending from the
casting 12, which finger in the axial movements of the handle in one direction,
comes in contact with the cam shaped end of the lever 15, pivotted in a recess in
the top part of the case. This lever has a projection extending from its upper
face across the upper surface of the rod c and thus as the lever 15 is depressed
through the axial movement of the handle to the right the springs d are compressed
and pressure applied to the brush. In Figure 4 a modification is shown of means
for applying pressure to the brush, consisting of a lever 15", pivotted beneath the
top of the case at one end, with its opposite end bent at right angles and extending
up through the opening in the case into line with the finger 14, which is adapted
to operate the same as before described. This lever 15 is held normally up by
the spring 16, and is provided with a pressure roller which bears upon the projecting
teeth on the periphery of the shaft of the main brush, and thus when the handle
is turned as above described pressure is applied directly to the shaft b and the
brush caused to bear more forcibly upon the surface to be swept.
The lever k has a lower extension 1, which is bent slightly to one side so as to
come directly over the curved upper surface of the finger 14, and in the axial
movement of the handle to the left the front end of the lever is depressed, over-
coming the pressure of the spring 5, and the supplemental brush thrust downward
in contact with the floor. Along the top of the head piece of the supplemental
brush is a rod preferably of spring material, this rod extending beyond the ends of
the head piece so as to engage with the outer ends of the lever 7 and thus as the
supplemental brush is brought into contact with the floor the ends of the spring
rod 17 bear with a yielding pressure upon the ends of the lever 7, thus increasing
the frictional contact of the discs of the brush c with the forward supporting wheels,
and causing them to be revolved. It will thus be seen by the arrangement described
that in one movement of the handle pressure may be applied to the main brush,
while in the reverse movement the main brush is released and the supplemental
brush placed under pressure.
This action is desirable for the reason that when it is desired to sweep close to
the wall the sweeper is placed in position with the supplemental brush in contact

page_text: with the wash board. The handle is then turned to the left, which brings the
supplemental brush in contact with the floor, while the main brush is out of contact
therewith.
The sweeper is then drawn outward from the wall, the supplemental brush
drawing the particles of dirt with it. The handle is then turned in the opposite
direction, thus relieving the supplemental brush and applying pressure to the main
brush, and the sweeper then advanced toward the wall taking up the dirt previously
withdrawn.
The side brushes C enable me to sweep along the sides of the room in close
proximity to the wash boards, and thus the floor may be thoroughly swept along
the sides to the corners of the room, and the dirt in the corners removed by the
action above described in alternately drawing the dirt out of the corners, and then
advancing the sweeper to take up the dirt thus withdrawn.
The dust pan has been simplified in my present construction of sweeper, being
made in a single piece and pivoted to the front end of the lower edge of the sweeper
with the ordinary opening in the bottom in line with the brush, the rear end of the
dust pan being removably held by catches which engage with the bent ends of a
pivoted rod held normally in engagement with the hooks by a spring. The pan is
shown at D, the hooks at m, and the pivoted rod at n.
up of
It will be understood that while I have shown my improved sweeper made
various improved elements, those various improvements may be applied to other
sweepers now in use, either in part or in whole, without departing from the spirit
of my invention.
I do not limit myself to the particular means shown for operating the supple-
mental brush as it is evident that the means shown may be varied in many ways,
and this is true also of the means for driving the main brush and applying pressure
thereto.
When the side wheels C C are dispensed with the supporting wheel or wheels for
the front may be arranged within the casing so as to be concealed.
The brushing tufts may also be dispensed with & the supplemental brush made
wide enough to extend to the line of the side brushes so as to take the place of
the tufts.
The exposed faces of the supplemental brush and side brushes may be covered
with any suitable material or provided with buffer pads to protect the furniture and
wash boards from becoming scratched in the use of the apparatus.
While I have described my improved sweeper in connection with the supple-
mental brush desire it to be understood that I may provide the supplemental
brush as an attachment to ordinary sweepers without regard to the general con-
struction of the sweeper. In Figures 5 and 6 1 show the supplemental brush as an
attachment capable of being readily applied to any form of sweeper without in any
way modifying the action of the sweeper except to make it more effective by adding
the function of the supplemental brush.
In these figures the brush is of the same general construction as shown in the
other figures. It is supported upon two levers, which have slotted ends
engaging studs or screws projecting from the rear face of the stock of the supple-
mental brush. The levers are bell cranks and are pivotted at a² to the
depending part-62 of a casting, which is secured to the casing of the sweeper and
serves to support the supplemental brush and operating parts. The lower ends of
the bell cranks all extend downwardly from the pivots and are connected to the
limbs of a spring the tendency being to throw apart the short arms of the bell
cranks lifting the long arms and thus keeping the brush elevated. In order to
depress the brush a cord e² connected to the brush or a standard thereon passes over
pulleys and through eyes to the handle, and by pulling on said cord the brush
is manipulated. It will be seen that the necessary connections to attach the brush
to an ordinary sweeper are few in number, simple in construction, and may be
applied by unskilled labor.
Instead of the part c² being a casting it may be made of sheet metal.
