IMPROVEMENTS IN CARRIAGE WASHING BRUSHES, APPLICABLE ALSO TO OTHER PURPOSES
Year: 1873

page_text: LETTERS PATENT to Charles Courtney Cramp, Engineer, of High
Street, Bow, Middlesex, for the Invention of "IMPROVEMENTS IN
CARRIAGE WASHING BRUSHES, APPLICABLE ALSO TO OTHER PURPOSES."
Sealed the 12th August 1873, and dated the 30th May 1873.
PROVISIONAL SPECIFICATION left by the said Charles Courtney
Cramp at the Office of the Commissioners of Patents, with his
Petition, on the 30th May 1873.
I, CHARLES COURTNEY CRAMP, Engineer, of High Street, Bow,
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CARRIAGE WASHING BRUSHES, APPLICABLE ALSO TO OTHER
PURPOSES," to be as follows :-
My Invention of hydraulic carriage brush consists of an improvement
in water brushes, whereby the water used not only supplies the brush
for work but also rinses the work completed.
The water is made to pass through the handle of the brush, which
is of iron tubing or other metal, and is conducted by a flat spray (which

page_text: is situated above the brush) on to the part of the carriage to be cleaned.
The dirt then becomes softened and allows the use of the brush for
removing the same. The water issuing from the jet or spray cleans the
work finished, and prepares the work immediately below it, the brush
being attached to the tube in such a manner that it may be easily
removed or renewed at any time. The flat spray may be made of india-
rubber instead of metal, and the water may be supplied to the spray by
an india-rubber tube instead of passing through the handle. The brush
may be used for floors, or windows, or walls.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Courtney Cramp in the Great Seal
Patent Office on the 27th November 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
COURTNEY CRAMP, Engineer, of High Street, Bow, Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of May, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Charles Courtney Cramp, Her
special licence that I, the said Charles Courtney Cramp, my executors,
administrators, and assigns, or such others as I, the said Charles Courtney
Cramp, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 In-
vention for "IMPROVEMENTS IN CARRIAGE WASHING BRUSHES, APPLICABLE ALSO
TO OTHER PURPOSES," upon the condition (amongst others) that I, the
said Charles Courtney Cramp, 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

page_text: Patent.
NOW KNOW YE, that I, the said Charles Courtney Cramp, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
My Invention of improvements in carriage washing brushes, applicable
also to other purposes, consists of an improvement in water brushes,
whereby the water used not only supplies the brush for work but also
rinses the work completed.
The water is made to pass through the handle of the brush, which is
of iron tubing or other metal or suitable material, and is conducted by
a flat spray (which is situated above the brush) on the part of the
carriage to be cleaned. The dirt then becomes softened and allows the
use of the brush for removing the same. The water issuing from the
jet or spray clears the work finished, and prepares the work immediately
below it, the brush being attached to the tube in such a manner that
it mny be easily removed or renewed at any time. The flat or other
formed spray may be made of india-rubber instead of metal, leather, or
other suitable material, and the water may be supplied to the spray by
an india-rubber, leather, or other tube, instead of passing through
the handle. The brushes may be used for floors, walls, windows,
urinals, or for any kind of carriage, truck, or machine.
Figs. 1 to 37, in the accompanying Drawings, show some forms of my
improved brush with details of the same.
Figs. 1 and 2 are respectively elevation and plan, and Fig. 10 a full
size section, through the nozzle of the brush, with a regulating joint J.
This is necessary where the angle of the work varies, as in ship's decks,
urinals, and other places. The nozzle N in this is formed of india-
rubber, lined with a slot of brass, or other suitable material, or the slot
may be outside the india-rubber S, Fig. 10; this will be found of great
service where the surface would be damaged by a scratch from a
hard material; in the Figs. P is the pipe for conveying water to the
brush B.

screwed into a T piece C; the nozzle N¹, of brass or other suitable
material, being formed separately; the handle of the brush P being
formed of common piping, and screwed or fastened in a suitable manner
into the T piece, as shown by Fig. 11.
Figs. 5 and 6 are respectively elevation and plan, and Fig. 12 is a
full size section, through nozzle, of a brush for carriage washing
purposes; the socket J" of this brush is cast solid with the bracket and
a stay rod. R is used in connection with another socket U, which
screws on the handle of the brush for strengthening it. The nozzle N¹¹
is of brass or other suitable material, giving plenty of strength, and the
india-rubber protecting the work from being scratched by the brass.
Fig. 7, 8, and 9, are respectively elevation, plan, and section, of a
suitable form of connection between pipe from hydrant and pipe of
brush.
Figs 13 to 24, inclusive, show details of the brush shown by Figs. 1,
2, and 10; Figs. 25 to 30, inclusive, show details of the brush shown
in Figs. 3, 4, and 11; Figs. 31 to 37, inclusive, show details of the
brush shown in Figs. 5, 6, and 12; like parts being indicated by
similar letters.
I am aware that brushes supplied with water through the handle have
been used before where the water has been carried through the handle
into the brush itself. I do not therefore claim such mode of washing,
but what I claim as new is delivering the water over and separate from
the brush, instead of through the brush. I do not confine myself to
the exact details or form described and shown in this Specification and
Drawings, as such may be varied to suit special cases.
In witness whereof, I, the said Charles Courtney Cramp, have
hereunto set my hand and seal, this Twenty-sixth day of
November in the year of our Lord 1873.
CHARLES COURTNEY CRAMP. (L.S.)
