CERTAIN IMPROVEMENTS IN THE MANUFACTURE AND HANGING OF WINDOW SASHES
Year: 1843

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BARROW, of East Street, Manchester Square, in the County of Middlesex,
Engineer and Smith, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-eighth day of January, in the sixth year of Her reign, did;
for Herself, Her heirs and successors, give and grant unto me, the said John
Barrow, Her especial licence, full power, sole privilege and authority, that I,
the said John Barrow, my exors, adñors, and assigns, or such others as I, the
said John Barrow, my exors, admors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, my Invention
of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE AND HANGING OF WINDOW
SASHES;" in which said Letters Patent is contained a proviso that I, the said
John Barrow, shall cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled in
Her said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent, as
in and by the same, reference being thereunto had, will more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Barrow, do hereby declare the nature of my said Invention to consist, as
regards the manufacture of sashes—
First, in an improved mode of forming window sashes with side guide
pieces working in side guide grooves, with inclined planes in certain parts of
them so as to hang flush, and yet to pass by each other when put up or down,
and with bevelled edges, so that when closed they shall be perfectly water-
tight, and not liable to rattle with the wind. And, secondly, in a self-acting
balance weight catch, to fasten the lower sash down when brought to its shut
position.
And, as regards the hanging of sashes, my Invention consists, first, in passing
the cords or other suspending media over adjusting pullies with weights contrived
to take up very little room, which is of importance particularly where the sashes
are set in stone mullions. And, secondly, in concealing the suspending cords
or other suspending media, while I dispense with the usual fastenings placed
at the meeting bars of the upper and lower sashes. And my Invention is of
such a nature that it will be particularly applicable to gothic and other
windows where casements are at present often used from the expense and
trouble there is in having sliding sashes; as, for instance, where there are stone
mullions between the lights, so much stone work has to be cut away to allow
room for the boxings and framing of the sashes as to render them almost
impracticable, while by my arrangement the sashes and frames may all be
removed together, leaving the weights in the stone mullions. And in further
compliance with the said proviso, I, the said John Barrow, do hereby describe
the manner in which my said Invention is to be performed by the following
statement thereof, reference being had to the Drawing annexed, and to the
figures and letters marked thereon, similar letters being used to denote, similar
parts in all the figures, that is to say:
DESCRIPTION OF THE DRAWING.
Figure 1 is a front elevation of the interior of a side light of a gothic
window in which the sashes are shewn closed.
Figure 2 is a vertical section of the same Figure, but shewing the lower
sash raised a little; and although I should recommend, and have shewn the
sashes and framing as being made of metal, yet my sashes are equally appli-
cable if made of wood, and in some cases I should construct them in that
Inaterial.

Figures 3 and 13 shew detached portions of the sashes and frames of the
full size, as also the fastening and the pulleys over which the sash lines or

page_text: chains pass. A is the upper, and B the lower sash; C, C, is the frame -in
which the sashes slide; this frame is made of metal and is complete in itself;
it is fixed to the stonework by screws, and it can be removed with the sashes
when required without the sash-lines or weights being also taken out; D, D,
are side grooves with inclined planes formed in the frame C, by which the lower
sash is brought in a line with the upper sash when closed, and detached from it
when it is required to open the sashes, there being side projections E, E, shown
separately at Figures 14, 16, & 17, on the lower sash, which work in the said
side grooves. F is a handle fixed on the lower sash, by which it is raised or
lowered; G is a catch which fastens the lower sash when closed and prevents
it being raised; it is mounted in the side pieces H, upon a pin I; and J is a
balance weight which keeps the catch against the projection or tongue K. of
the handle F. In order to release the sash the bolt Q must be pushed
inwards, which will lower the point of the catch and free it from the projection
or tongue K. I have shewn this catch in detail in the detached Figures 4, 5,
and 6; R, R, are two pullies which turn on pins fixed in a carriage S, which
carriage slides upon two studs T, T, fixed in the plates U, V; the plate U is
fastened to the stone work of the window by screws, and the plate V is also
let into a groove in the stone work, see Figure 7. The pulley carriage Sis
made to slide, for the purpose of allowing the pullies (which project through
and before the frame when the sashes are placed in it) to be withdrawn
behind the plate U when it is required to take out the sash frame from the
stone work; this is effected by turning the screw W, the head.of which passes.
through the front plate U, and is tapped into the pulley carriage S and counter
sunk into the back plate V, so that when it is turned the carriage will work to
and fro upon the thread of the screw.
In Figure 15 I have shewn the pullies as having retired behind the front
plate U.
Figures 8, 9, 10, & 15, shew detached views of the pullies, carriage,
and plates just described. X, X, are cords by which the sashes are suspended
they are connected thereto by loops & hooks Y, Y, fixed to the side guide
pieces of the sashes, and the other ends of the cords are attached to weights
Z, Z, which slide in a groove a, formed in the stone work, as seen best in
Figure 7, which Figure is a transverse section of a stone mullion of a window,
one half taken at the level of the pullies and the other half near the weights.
In order to remove the frame from the stone work, it is necessary to make the
pulleys recede behind the plate U; for this purpose a piece d, of the frame C
which covers the head of the screw W, and which is supposed to be removed
in Figure 3, is made moveable to be able to turn the screw; this piece is shown

page_text: detached in Figures 11 and 12; c, c, are mouldings which are screwed to the
frame C, which act as guides for the sashes to slide in, and cover up the sus-
pending cords to protect them from dirt and to prevent their being seen; these
will be best seen in Figure 7.
Now whereas I claim as my Invention the Improvements in the Manu-
facturing and Hanging of Window Sashes herein-before described. And such
my Invention being, to the best of my knowledge and belief, entirely new and
never before used within that part of Her said Majesty's United Kingdom of
Great Britain and Ireland called England, Her said Dominion of Wales, or
Town of Berwick-upon-Tweed, I do hereby declare this to be my Specification
of the same, and that I do verily believe this, my said Specification, doth
comply in all respects, fully and without reserve or disguise, with the proviso
in the said herein-before in part recited Letters Patent contained, wherefore
I do hereby claim to maintain exclusive right and privilege to my said
Invention.
In witness whereof, I, the said John Barrow, have hereunto set my hand
Enrolled the Twenty-eighth day of July, in the year of our Lord One
thousand eight hundred and forty-three.
