page_text: LETTERS PATENT to George Warsop, of 60, Mount Street, Nottingham,,
for the Invention of "IMPROVEMENTS IN APPARATUS FOR CLEANING"
WINDOWS."
Sealed the 4th February 1868, and dated the 10th August 1867.
PROVISIONAL SPECIFICATION left by the said George Warsop at the
Office of the Commissioners of Patents, with his Petition, on the
10th August 1867. .
I, GEORGE WARSOP, of 60, Mount Street, Nottingham, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR CLEANING.
WINDOWS," to be as follows:-
The main object of this Invention is to enable persons to clean the outside
of a window-from-the-interior of the room or chamber to which the window
belongs. I employ for this purpose a frame which clamps on to the window
sill or ledge,,and on this frame I mount a horizontal axis perpendicular to the
plane of the window-or-thereabout; this axis carries a stud on one sido, on
which another lever is mounted; it has a handle on its inner end, and at its

page_text: ;
outer end a socket is carried on spindles parallel to the stud on which this
lever turns into this socket there is fitted a long rod having at its upper
end a brush and rubber for cleaning the window. By means of a spring this
rod is drawn inward so as to cause the brush or rubber at its end to press
against the outer surface of the window; then by working the handle up and
down whilst the horizontal axis is caused to rock the brush or rubber may be
moved over every part of the surface of the window. The horizontal axis
may be controlled either by a bandle upon it or by grasping and guiding the
cleaning rod on the outside of the window. Any convenient form of brush
may be fitted to the upper end of the cleaning rod; it is made removeable at
pleasure, and the rubber I employ consists of a palm or flat surface of
rectangular form with a projection at the back which is jointed to the upper
end of the rod, and the joint is so formed as to allow sufficient freedom to the
palm or surface to turn every way, so that it may at all times rest flat against
the glass, and also that its angles may be able to enter the corners of the
window panes.
Where the surface of the window glass is curved the palm
should be curved to correspond. The palm is first used with a wet leather and
afterwards with a dry cloth. The cleaning rod with its palm and brush will
also be found a very convenient apparatus for cleaning the insides of windows
and internal paint.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Warsop in the Great Seal Patent Office on the 10th
February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
WARSOP, of 60, Mount Street, Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of August, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her- heirs and successors, give and grant unto me,
the said George Warsop, Her special licence that I, the said George Warsop,
my executors, administrators, and assigns, or such others as I, the said George
Warsop, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter. during
the term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS. FOR

page_text: CLEANING WINDOWS," upon the condition (amongst others) that I, the said George.
Warsop, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said George Warsop, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
The main object of this Invention is to enable persons to clean the outside of
a window from the interior of the room or chamber to which the window
belongs. I employ for this purpose a frame which clamps on to the window
cill or ledge, and on this frame I mount an horizontal axis perpendicular to.
the plane of the window or thereabout; this axis carries a stud on one side, on
which a lever is mounted; it has a handle on its inner end, and at its outer end
a socket is carried on spindles parallel to, the stud on which this lever turns ;
into this socket there is fitted a long rod having at its upper end a brush and
rubber for cleaning the window. By means of a spring this rod is drawn
inwards so as to cause the brush or rubber at its end to press against the
outer surface of the window; then by working the handle up and down whilst
the horizontal axis is caused to rock the brush or rubber may be moved over
every part of the surface of the window. The horizontal axis may be con-
trolled either by a handle upon it or by grasping and guiding the cleaning rod
on the outside of the window. Any convenient form of brush may be fitted to
the upper end of the cleaning rod; it is made removeable at pleasure, and the
rubber I employ consists of a palm or flat surface of rectangular form with a
projection at the back, which is jointed to the upper end of the rod, and the
joint is so formed as to allow sufficient freedom to the palm or surface to turn
every way, so that it may at all times rest flat against the glass, and also that
its angles may be able to enter the corners of the window panes. Where the
surface of the window glass is curved the palm should be curved to correspond.
The palm is first used. with a wet leather and afterwards with a dry cloth. The
5 cleaning. rod with its palm and brush will also be found a very convenient
apparatus for cleaning the insides of windows and internal paint.
And in order that my said Invention may be most fully understood and
readily carried into effect I will proceed to describe the Drawings hereunto

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view; and Figure 2 is a plan partly in section of
'the same.
a, a, is the frame of the apparatus; it is conveniently made in cast iron, and
with it is formed the jaw a¹; b is another jaw able to slide on the frame a, with
which it is connected by a screw passing through the slot a so that the jaw b
can traverse a distance equal to the length of this slot; c is a screw, it has a
handle at its outer end and passes through the guides a³ and a' on the frame a.
The inner guide a' has a screw thread cut in it so that the screw c when
turned traverses longitudinally through it; the inner end of the screw is
attached to the jaw b, but so as to be able to turn. The jaws a and b when
the apparatus is set up for use are caused. by means of the screw to grasp the
window or ledge and so the frame a is securely fixed; d is an adjustable
foot, which is employed in order further to steady the apparatus; it has a screw
stem passing through a tapped hole in the jaw b, and after the apparatus has
been clamped in its place this font is screwed down until it finds a firm
hearing. e is a horizontal axis carried by the frame a in bearings at a³, a³ ; it
bas upon it at one end a handle e', and it also carries a stud e on which the
hand lever fis able to rock; this lever at its end, which is within the room or
chamber,
has a handle upon it, and at its outer end which is forked is a socket
g; it has spindles or studs 9', 9', upon it, .which are received into holes in the
forked end of the lever f so that the socket is able to rock on the lever. his
a stick able to slide through the socket, but secured when in use in desired
position by a small key or wedge driven in between the stick and the side of
the socket; is a lengthening piece secured to the upper end of the stick h
and locked by the spring catch h¹; at its upper end it has fixed to it the cross-
head k, one end of which carries the brush l, and over the other end a socket
m passes; it is retained in its place by a screw entering a garter groove passing
around the end of the cross head, thus the socket is able to turn partly
round on the cross head, but a spring n pressing upon a flattened side of the
socket tends to bring it constantly to one position and keep it steady. o is a
plate or palm; it is carried by the socket m, a projection from the back of the
palm being pin-jointed to it; the surface of the palm is covered with the
rubbing leather or cloth. p is a vulcanized india-rubber spring passing from a
projection f on the lever f to another projection g' on the socket
to press the broom or palm o (whichever is for the time being in use) against
the glass of the window to be cleaned. When at work the operator holds in
his hands the handle e¹ and the handle on the end of the lever f; by the
any
g;
it serves

page_text: hand lever f the brush or palm is worked up and down, and simultaneously it
is traversed sideways by moving the handle el to and fro, in this way the brush
or palm is caused to pass over.every part of the surface to be cleaned. When
the portion of the surface within reach is thoroughly cleaned the stick h is shifted
up or down in the socket g¹ and another part of the surface of the window is
operated on, and so on until the work is complete. The method of mounting
the palm allows it to adapt itself to the corner of the panes so as to come
in contact with every part of the surface.!
In witness whereof, I, the said George Warsop, have hereunto set my
hand and seal, this Sixth day of February, in the year of our Lord
One thousand eight hundred and sixty-eight.
GEORGE WARSOP. (L.s.)
