Year: 1852

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
KNOTT PARKER, of London Wall, in the City of London, Carpenter, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Twenty-second day of May,
One thousand eight hundred and fifty-two, in the fifteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Knott Parker, my exors, admors, and assigns, Her especial license,
full power, sole privilege and authority, that I, the said Thomas Knott
Parker, my exors, adññiors, and assigns, or such others as I, the said. Thomas
Knott Parker, my exors, adñors, 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 "IMPROVEMENTS IN WINDOW SASHES;" in which said Letters Patent is
contained a proviso that I, the said Thomas Knott Parker, shall cause
a particular description of the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under
my hand and seal, to be inrolled in Her 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
Thomas Knott Parker, do hereby declare that the nature of the said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the present Specification thereof,
reference being had to the Drawings hereunto annexed, that is to say :-
My Invention has for its object the so constructing and arranging the
sashing of windows that they can with facility be opened for the purpose of
either cleaning or glazing, and be again readily re-adjusted.
Figure 1 in the Drawing hereunto annexed represents the front elevation
of a window constructed according to my said improvements; in this Figure
the sashes are represented in their usual position in the frames. Figure 2 is
a similar front elevation representing the sashes when opened for the purpose
of cleaning or otherwise; Figure 3 is a section of Figure I; and Figure 4, a
section of Figure 2. A, A, is the framework; and B, C, the sashes; D, D¹,
and E, E¹, are pieces which slide up and down in the grooves formed by the
sides of the framework A, A, and the centre beadings a, a.
These pieces
form the runners for the sashes B, C, being weighted in the manner usually
adopted in the ordinary kind of sashes. The bottom sash B is hinged at one
side to the runner D₁ by the hinges F, F, while the other side is attached to
the opposite runner D by the two thumb-screws G, G. The top sash C is
also connected to the runner E' by means of two pins which project from the
upper and under sides, and take into holes in the end of two pieces of metal
c, c, fastened to the runners E¹. The opposite side of the sash is connected to
the runner E by the thumb-screw H. I, I, are pins which pass through holes in
the frame A, A, and runners D and E, to retain them in any particular position
in which they may be placed. When it is desired to open the sashes for
the purpose of cleaning, glazing, &c., the top sash is lowered until it rests upon
two blocks d, d, shewn in dotted lines in Figures 1 and 2, placed at the bottom
of the frame. The bottom sash is then slightly raised from out of the recess
in the bottom of the frame until the tops of the two sashes are flush with each
other. The pins I, I, are next removed from out of the holes in which they
were previously placed and inserted through the holes d', d', in the frame and
through corresponding holes in the runners D and E, which prevents the
runners, when the screws G, G, and H, H, are removed, from being drawn
to the top of the framing by means of the counter-balance weights. Upon the
removal of the thumb-screws G and H, the sashes are free to turn upon their
hinges, and can be opened and brought into a position at right angles to the
.framework, whereby they are capable of being more easily cleaned or glazed
than hitherto, and new lines may then be attached to the runners without

first turned back into their place, the thumb-screws G and HI re-inserted, and
the pins I, I, placed back into their former holes, and the sashes are again
free to slide up and down, as before. The sides of the sashes are rabbeted into
the runners, as shewn, in order to prevent the wind or rain from entering the
interior of the apartment. Instead of using the thumb-screws G and II for
attaching the sashes to the runners, small bolts may be applied, but I prefer
the screws, as being less liable to derangement. Where the sashes are of a
large size, I make use of an additional thumb-screw to the top sash, as shewn
at K, Figure 1.
And having now described the nature of my said Invention, and the manner
in which the same is to be performed, I declare that what I claim is, the
particular construction and arrangement of window sashes, as herein-before
described and represented in the Drawings hereunto annexed.
In witness whereof, I, the said Thomas Knott Parker, have hereunto
set my hand and seal, this Twenty-second day of November, in the
year of our Lord One thousand eight hundred and fifty-two.
