IMPROVEMENTS IN WINDOW FRAMES AND SASHES
Year: 1853

page_text: LETTERS PATENT Edward Patrick Gribbon, of the City of Dublin,
Architect, for the Invention of "IMPROVEMENTS IN WINDOW FRAMES
AND SASHES."
Sealed the 14th December 1853, and dated the 29th August 1853.
PROVISIONAL SPECIFICATION left by the said Edward Patrick
Gribbon at the Office of the Commissioners of Patents, with his
Petition, on the 29th August 1853.
I, EDWARD PATRICK GRIBBON, of the City of Dublin, Architect, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
WINDOW FRAMES AND SASHES to be as follows:-
I make one pulley style wholly or partially moveable, so as to widen
the space between the two pulley styles to such extent as to allow the
sash to be pulled clear out of the bead of the opposite pulley style. I
fasten the weight lines to the sashes by means of metal plates with a
large orifice at bottom for receiving a knot on the end of the line, which
then passes up a slot in the plate, and is held secure. In order to free
the sash the line must be pulled down until the knot reaches the orifice
at the bottom of the plate, through which it will readily pass. My In-

page_text: vention can be applied to altering frames and sashes as at present made,
as also to the construction of new frames and sashes. By my In-
vention sashes can be unfixed and refixed, unhung and rehung, by
hand, without the aid of a carpenter.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Patrick Gribbon in the Great Seal Patent
Office on the 28th February 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
EDWARD PATRICK GRIBBON, of the City of Dublin, Architect, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of August, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Edward Patrick Gribbon,
Her special licence that I, the said Edward Patrick Gribbon, my
executors, administrators, and assigns, or such others as I, the said
Edward Patrick Gribbon, 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 Edward
Patrick Gribbon, 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 Edward Patrick Gribbon, 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

page_text: in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, (that is to say):
My Invention consists in constructing and fitting window frames and
sashes in such manner that the sashes can be unfixed and refixed, un-
hung and rehung, by hand, without the use of a hammer and chisel or
other instrument, and without unfixing the sash beads.
In carrying my Invention into effect I make, one pulley style wholly
or partially moveable, so as to widen the space between the two pulley
styles to such an extent as to allow the sash to be pulled clear out of
the bead of the opposite pulley style; and when both the upper and
lower sashes are required to be unhung, then I make both pulley styles
wholly or partially moveable in a similar manner, one for the lower,
and the other for the upper sash. I fasten the weight lines to the
sashes by means of metal plates, having a slot with an enlarged orifice
at the bottom for receiving the knot at the end of the line, which then
passes up the slot in the plate, and is thus held secure. In order to free
the sash the line must be pulled down until the knot reaches the
orifice at the bottom of the slot in the plate, through which it will
readily pass, so as to become detached from the sash. The line is pre-
vented from chafing while the sash is hung by lying in a groove cut
along the edge of the sash for that purpose. My Invention can be
applied to altering window frames and sashes as at present arranged
and fitted, as well as to the construction of new frames and sashes.
Figure 1, of the Drawings annexed is a sectional elevation, and
Figure 1", a cross section on the line a, a, of a window frame and
sash, having a portion of both pulley styles moveable, shewing the
moveable portions of the pulley styles hinged to the fixed parts thereof
so as to admit of their being opened or thrown back for the removal of
the sashes. A, A, is the window frame; and B, the lower sash. C, C¹,
are the moveable portions of the pulley styles, which are connected to
the fixed parts thereof by means of the hinges D, E, and D¹, E. The
peculiar construction of these hinges is more clearly shewn in Figures
2, 3, and 4, of which Figure 2, is a vertical section shewing the move-
able part of the pulley style C', thrown back, and forming a recess into
which one side of the upper sash passes, to enable the other side to
move clear of the bead F, on the style C. Figure 3, a vertical section

page_text: shewing the moveable part of the pulley style C', at rest; and Figure 4,
a front elevation of the parts in the same position. The pulleys G, G',
over which the weight lines run, are fixed in the moveable parts of the
pulley styles, and the weight of the sash and sash weights thrown
thereon keeps them closed. A bolt or fastening pin might be added, but I
do not consider it necessary. Although I have described a window frame
having a portion of both pulley styles moveable, this might not always
be necessary, and one pulley style only might be made moveable, and this
might be done in such a way as to enable both sashes to be removed
thereby; but I prefer the arrangement above described, without how-
ever confining myself to the use of hinges of the peculiar construction
mentioned, although I believe they will be found the most convenient for
general use. In cases where there is only space enough for the weight
behind the pulley style, and where the weight would not admit of the
removed portion of the pulley style receding far enough to allow of the
sash being withdrawn, or where other circumstances render it desirable,
I substitute for that part of the style made to recede a thin plate of
metal or a piece of wood of less thickness than that of which the other
portions of the pulley style are composed.
Figure 5, is an edge view, and Figure 6, a vertical section of part of
a window sash, shewing the means which I adopt for attaching the sash
lines so as to enable the sashes to be readily unhung when removed
from the window frame, as before described, and rehung when required
to be replaced. C, is part of the sash frame; I, the sash line,
knotted at its lower end, the other end passing over the sash pulley, and
being secured to the sash weight in the ordinary manner. K, is the
groove in the edge of the sash frame in which the sash line lies; L,
the slotted plate with enlarged orifice for the entrance of the knot on
the sash line; and M, a stop at the back of the plate against which the
knot of the sash line is held. This method of securing the sash lines
may also be used independent of my improvements herein-before
described.
And having now described the nature of my said Invention, and in
what manner the same may be performed, I declare that what I
claim is,―
First, the making of one or both pulley styles of window frames

page_text: wholly or partially moveable, for the purpose herein-before men-
tioned; and,
Second, the mode of securing the weight lines to the sashes, so as to
enable them to be readily attached thereto and detached therefrom, as
herein-before described.
In witness whereof, I, the said Edward Patrick Gribbon, have
hereunto set my hand and seal, this Ninth day of February,
One thousand eight hundred and fifty-four.
E. P. GRIBBON. (L.S.)
