Year: 1860

page_text: LETTERS PATENT to William Henry Elkin, of No. 27, Belvedere Road,
in the Parish of Saint Mary, Lambeth, in the County of Surrey, Joiner,
for the Invention of "IMPROVEMENTS IN WINDOW FRAMES AND SASHES."
PROVISIONAL SPECIFICATION left by the said William Henry Elkin at
the Office of the Commissioners of Patents, with his Petition, on the
16th February 1860.
I, WILLIAM HENRY ELKIN, residing at No. 27, Belvedere Road, in the
Parish of St. Mary, Lambeth, in the County of Surrey, Joiner, do hereby.
declare the nature of the said Invention for "IMPROVEMENTS IN WINDOW FRAMES
AND SASHES," to be as follows:-
Firstly, this Invention consists of an arrangement which by placing the sash
near the centre of the frame and pressing it firmly against the pulley stile,
which falls back by means of springs fixed at each end, allowing the sash to
pass the bead on the opposite side of the frame, and its entire removal
therefrom.
Secondly, by means of a loop at the end of the sash line being made to pass
over the head of a screw fixed near the centre of the sash stile, the line can be
instantly disconnected from the sash.
Thirdly, by pressing against and lifting the pulley stile, it becomes released

page_text: from the sash sill by means of a groove in the head of the sash frame, and is
then instantly removed.
By the above method the window may be cleaned or repaired without
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Henry Elkin in the Great Seal Patent Office on
the 31st July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY ELKIN, of No. 27, Belvedere Road, in the Parish of Saint Mary,
Lambeth, in the County of Surrey, Joiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of February, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Henry Elkin, Her special licence that I, the said William
Henry Elkin, my executors; administrators, and, assigns, or such- others as I,
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 WINDOW
FRAMES AND SASHES," upon the condition, amongst others, that I, the said
William Henry Elkin, by an instrument in writing under my hand and
seal, 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 William Henry Elkin, 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):-
The improvement introduced by this Invention into the manufacture of
windows and their appurtenances consists in a peculiar arrangement of the
parts of the same whereby the sashes or shutters used in the same are main
tained fixedly in their position without rattling, and by which the said sashes,
shutters, or other parts of the same can at any time be removed for the

page_text: purpose
of readjustment or repair without disturbing the paint or injuring the
woodwork. The said parts of the windows are thus arranged:-The portion
technically called the pulley-style is made loose, being kept in its place and
pressed equably against the sash or shutter by means of springs at either end
of it. One or both of the pulley-styles may be thus fitted, but it is found in
practice that the purpose is sufficiently answered by making only one of the
pulley-styles moveable. Sashes and shutters made on this principle may be
used with or without weights and pulleys, according to the size and character
of the window. If fitted with weights and pulleys, the sash-line is hooked over
a screw head or button fixed to the sash or shutter instead of being nailed to
the sash, as is at present universally done.
The removal of the sash or shutter is effected by pressing it sideways against
the spring pulley-style, which yields sufficiently to allow the sash to be
disengaged from the beads of the opposite pulley-style. The free side is then
drawn inwards, and the other side of the sash liberated from the beads of the
spring-style. In cases where a sash-line is used, the same is then unfastened,.
and the sash or shutter is disengaged.
The pulley-style may also be casily taken out of the frame to repair the
weights or lines.
Having thus described the nature of my said Invention, and the best means
with which I am acquainted for carrying the same into effect, I claim the sole
right to make, use, exercise, and vend the same manufactured in the manner
herein-before mentioned.
In witness whereof, I, the said William Henry Elkin, have hereunto set
my hand and seal, this Twenty-seventh day of July, in the year of our
Lord One thousand eight hundred and sixty.
WILLIAM HENRY ELKIN. (L.S.)
