I, WILLIAM BAINBRIDGE BROOKER 24 Peveril Street Breeze Hill Walton Liverpool
Clerk and Collector do hereby declare the nature of this invention to be as
follows:-
A portable revolving brush, that may be worked and used at the same time, by the
hands of one and the same person.
The machine consists of a hollow drum running on a tubular spindle, the latter
having a sliding bar of about its own length inserted within it.
At one end, the spindle forms a handle to be grasped by the hand, and at the other
end, the sliding bar projects, and has a handle for the other hand.
When the spindle and sliding bar are held in the two hands the drum will be
between them, and is kept in its place by the hub of the handle at one hand, and by a
nut attached to the end of the spindle at the other end.
The spindle and sliding bar do not revolve. The revolving motion of the drum is
caused by the movement of the sliding bar inwards, and outwards, and the latter is
pushed and drawn by the hand of the operator.
The motion of the sliding bar is communicated to the drum by means of cords, or
small chains, attached to the sliding bar, and the following described intermediate
machinery, situate within the drum.
Inside the drum, and running on the same spindle, there are two wheels, one at each
end; these wheels have each a coil spring so attached, that they will cause the wheels
to return back again, when released, after having been pulled round, say about half, or
a whole revolution; they have each three palls attached, radiating outwards, and
projecting a little beyond the edge of the wheels, and inclined a little at a tangent, all
in the saine direction.
These palls are pressed against the inside surface of the drum, by means of a small
spring attached to each, so that when the wheels are turned round on their axis, in
the direction in which the palls point, they will carry the drum round with them, but
on allowing them to return, in response to the action of the coil springs contained
within them, they will not carry the drum back again.
To work these wheels, one end of each of the before mentioned chains, are attached
to them, one to each wheel, and laid in grooves, round the wheels, about three-quarters

of the circumference, the remaining length of the chain being led away, each bending
round two small grooved pulleys, placed at right angles to the spring wheels, and.
thence through an opening, made for the purpose, into the inside of the spindle,
where they are attached by their ends to the sliding bar, one chain to each end of the
same.
The two grooved pulleys just mentioned, are mounted on projections attached to
the spindle, and are placed as follows:-The two wheels nearest to the sliding bar,
are midway between the ends of the drum, one at each side of the spindle, and
projecting a little way within it, so that their grooves may receive the chains and
carry them near to the inside circumference of the drum the remaining two are
near to the edges of the spring wheels, where the chains are again bent at right
angles round the grooved pulleys and thereby led into the grooves round the edges of
the spring wheels.
The chains being fastened, one to one end of the sliding bar, and the other to the
other end of the sliding bar, will necessarily work reciprocally when the bar is moved,
one being pulled outwards from the drum, into the spindle, while the other is returning
to the inside of the drum, in response to the returning action of its spring wheel.
There is room for the chains inside the spindle, one along each side of the sliding
bar, by means of grooves for the purpose in the latter, or by means of its being of a
flat section.
The sliding bar is prevented from turning round, inside the spindle, by means of
grooves along the inside of the spindle, and counterparts on the sliding bar, to slide
in them.
To equalise the action of the drum, a small flywheel is mounted on a projection
attached to the spindle outside of the drum; The flywheel is driven by an endless
band, laid round a grooved wheel, on the end of the drum, and a groovd pulley, on
the spindle of the flywheel.
To the outside of the drum, and radiating outwards, bristles, or else wires are
attached, to form the brush.
The whole of the machine may be made of metal; but the lags on the drum for
mounting the bristles, are preferably of wood or other suitable material.

page_text: I WILLIAM BAINBRIDGE BROOKER of 9 Viola Street Stanley Road Bootle, late of
24 Peveril Street Walton Clerk 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 :-
The machine consists of a hollow drum A running on a tubular spindle B, the latter
having a sliding bar of about its own length inserted within it.
At one end the spindle forins a handle D to be grasped by the hand, and at the
other end the sliding bar projects, and has a handle E attached for the other hand of
the operator.
When the spindle and sliding bar are held in the two hands the drum will be
between them, and is kept in its place by the hub of the handle D at one end, and by
a nut F attached to the end of the spindle, at the other end.
The spindle and sliding bar do not revolve.
The revolving motion of the drum is caused by the movement of the sliding bar
inwards and outwards, and the latter is pushed and drawn by the hand of the
operator.
The motion of the sliding bar is communicated to the drum, by means of cords, or
else chains G attached to the sliding bar and the following described intermediate
machinery, situate within the drum.
Inside the drum, and running on the same spindle, there are two wheels H, one
at each end; these wheels have each a coil spring so attached that they will cause
the wheels to return back again when released, after having been pulled round say
about half or a whole revolution; they have each three palls I attached, radiating
outwards, and projecting a little beyond the edge of the wheels, and inclined a little
towards a tangent, all in the same direction.
These palls are pressed against the inside surface of the drum by means of a small
spring attached to each, so that when the wheels are turned round on their axis in the
direction in which the palls point, they will carry the drum with them, but on
allowing them to return in response to the action of the coil springs contained within
them, they will not carry the drum back again.
To work these wheels, one end of each of the before-mentioned chains are
attached to them, one to each wheel, and laid in grooves round the wheels about three
quarters of the circumference, the remaining length of the chains being led away,
each bending round two grooved pulleys K placed at right angles to the spring
wheels, and thence through an opening made for the purpose, into the inside of the
spindle, where they are attached by their ends to the sliding bar, one chain to each
end of the same.
The four grooved pulleys just mentioned are mounted on projections L attached to
the spindle and are placed as follows:-The two wheels nearest to the sliding bar are
midway between the ends of the drum, one at each side of the spindle and projecting
a little way within it, so that their grooves may receive the chains, and carry them
near to the inside circumference of the drum, the remaining two are near the edges of
the spring wheels, where the chains are again bent at right angles round the grooved
pulleys, and thereby led into the grooves round the edges of the spring wheels.

page_text: The chains being fastened, one to one end of the sliding bar, and the other to the
other end of the sliding bar, will necessarily work reciprocally when the bar is moved,
one being pulled outwards from the drum into the spindle, while the other is
returning to the inside of the drum in response to the returning action of its spring
wheel.
There is room for the chains inside the spindle, one along each side of the sliding
bar, by means of grooves for the purpose in the latter, or by means of its being of a
flat section.
The sliding bar is prevented from turning round inside the spindle by means of
grooves along the inside of the spindle, and counterparts on the sliding bar to slide
in them.
:
To equalize the action of the drum, a small flywheel M is mounted on a projection
attached to the spindle outside of the drum the flywheel is driven by an endless
band N, laid round a grooved wheel O on the end of the drum and a small grooved
pulley (P) on the spindle of the flywheel. The latter is mounted on a movable bush
working in a slide formed in the aforesaid projection, and pressed by a spiral
spring (R) outwards so as to keep the band always tight.
The accompanying drawing (No. 1) shews the various parts of the machine
generally, of the size of one already made, but the sizes may be varied.
The plan (No. 2) is intended to elucidate the description of the two spring wheels,
which are both alike in size and principle, but are right and left in make (one right
and one left for each machine.) The plan shews one of these in three different positions,.
viz.a flat view of one side shewing the pawls and pawl-springs; One flat view
shewing the spring barrell, and position of the chain groove; and a third view, the
section, shewing where the ends of the coil springs are fastened, and a section of one
of the pawls attached.
The numbers and parts are as follows:-
4. Hole for spindle.
5. Spring barrell.
6. Chain (or cord) grooves.
7. Outer-edge of wheel.
8. Inner circle of drum, shewing ends of pawls bearing upon it, (at a slight angle
from the line of the centres).
9. Pawls.
10. do. springs.
11. Fastening for outer-end of coil spring.
12. Fastening for inner end of coil spring.
KL are also shewn by these letters on the No. 1 drawing.
To the outside of the drum and radiating outwards, bristles or else wires are
attached to form the brush.
The whole of the machine may be made of metal; but the lags on the drum for
mounting the bristles, and the handles are preferably of wood or other suitable
materials.
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 ;
The construction of machinery substantially in the manner hereinbefore described
for revolving brushes.
