Year: 1869

page_text: LETTERS PATENT to Thomas Cockcroft, of Bridge Lanes, Hebden
Bridge, in the County of York, Joiner, for the Invention of
"IMPROVED MEANS AND METHOD OF HANGING WINDOW SASHES."
Sealed the 2nd November 1869, and dated the 4th May 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Cockcroft at
the Office of the Commissioners of Patents, with his Petition, on
the 4th May 1869.
I, THOMAS COCKCROFT, of Bridge Lanes, Hebden Bridge, in the
County of York, Joiner, do hereby declare the nature of the said Inven-*
tion for "IMPROVED MEANS AND METHOD OF HANGING WINDOW SASHES," to be
as follows:-
This Invention consists in coupling and suspending the two parts or
sheets of a sash together by one cord and pulley at each side of the

page_text: window, and thereby dispensing with sash weights, and consequently all
preparations for their movements behind the frame, and the making of
pockets for access thereto; also only requiring two pullies and cords to
each sash of two sheets instead of four as heretofore.
By this Invention the costs of hanging sashes are considerably
reduced, and also less wear and tear, with greater facilities for taking
sashes out of their frames for repairs or other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Cockcroft in the Great Seal Patent Office
on the 4th November 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
COCKCROFT, of Bridge Lanes, Hebden Bridge, in the County of York,
Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of our
Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Thomas Cockcroft, Her special licence that I,
the said Thomas Cockcroft, my executors, administrators, and assigns, or
such others as I, the said Thomas Cockcroft, my executors, adminis-
trators, 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 "IMPROVED MEANS AND METHOD OF
HANGING WINDOW SASHES," upon the condition (amongst others) that. I,
the said Thomas Cockcroft, 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 Oflice within

page_text: NOW KNOW YE, that I, the said Thomas Cockcroft, 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 (that is to say) :-
This Invention consists in coupling and suspending the two parts or
sheets of a sash together by one cord and pulley at each side of the
window, and thereby dispensing with sash weights, and consequently all
preparations for their movements behind the frame, and the making of
pockets for access thereto; also only requiring two pullies and cords to
each sash or window of two sheets instead of four as heretofore.
By this Invention the costs of hanging sashes are considerably
reduced, and there is also less wear and tear thereof, with greater
facilities for taking sashes out of their frames for repairs or other
purposes.
The manner in which this Invention is or may be performed or put
into practical operation will be readily understood by all those who are
conversant with the usual mode and means of hanging window sashes;
but I may however state that an ordinary sash cord pulley may be
mounted on a stud fixed in a plate of convenient size, and such plate let
in or recessed into the sash frame within on both sides near the top and
screwed fast. The sash cords pass over these pullies, and are connected
to the two sashes or sheets, one cord to both sashes and one cord to each
pulley, so that one sash balances and suspends the other sash.
Or instead of using ordinary sash cord and pullies I may use any
suitable kind of chain, and have the pullies made suitable for the
chain.
Having thus described the nature of the said Invention, and the
manner in which the same is or may be performed, I would bave it
understood that I do not confine myself to any particular details of the
fixings or means used; but I claim, the method herein set forth of
hanging window sashes so that one sash will balance the other, or as

page_text: near so as may be desirable, and thereby avoid the use of sash weights
and other necessary preparations for them.
In witness whercof, I, the said Thomas Cockcroft, have hereunto
set my hand and seal, this Third day of November One thousand
eight hundred and sixty-nine,
Signed, sealed, and delivered
by the within-named Thomas
Cockcroft, in the presence of
WM. TASKER,
Patent Agent,
THOMAS COCKCROFT. (L.S.)
