Improvements in Windows.
I EDWARD ARNOLD RADCLYFFE of Council Chambers 109 Colmore Row
Birmingham in the County of Warwick Architect and Surveyor, do hereby declare
the nature of this invention to be as follows:-
This invention does away with the usual weights for hanging sash windows and
also the boxing to same. By dividing my window into four six or other equal
number of sashes other than two and carrying them on pulleys fixed at the top of
the frame & suspend each pair of sashes by chain, cord, or any other suitable
material.
+
I will describe my invention as applied to a window divided into four sashes
which is the number I prefer to use although the novel features of my invention
apply to any equal number other than two.
1 divide the frame with fillets (in the usual way) to form four stiles to receive the
sashes and fix at the top below the head of the frame one pair of single pulleys and
one pair of double pulleys on each side of the frame, the single pulleys being placed
with the double ones between them. I place the bottom sash in its usual position,
on the inner face of the frame and the top sash in its usual position on the outer
face of the frame and connect these sashes by means of cords or chains passing from
the one to the other over the single pulleys using one pulley of each of the double
intermediate pulleys as guides. The other two sashes are connected together by
cords or chains over the remaining wheels of the double pulleys.
I can when I so desire use only one double pulley for these middle sashes.
The top and bottom rails of each sash being rebated so as to overlap the
adjoining one and the raising of the bottom sash causing the lowering of the top
one, when these are sufficiently moved to come in contact with the other sashes
they will all travel on until they have overlapped one another to the extent of one
half the height they occupy thereby causing a larger portion to be open than is the
case with sash windows hung in a similar manner but as only two sashes.
By constructing the windows as above described any bolt, spring catch or other
device placed at the bottom of the bottom sash when fastened will securely prevent
the opening of any of the sashes.

COMPLETE SPECIFICATION.
Improvements in Windows.,
I, EDWARD ARNOLD RADCLIFFE of Council Chambers 109 Colmore Row,
Birmingham, in the County of Warwick, Architect and Surveyor do hereby
declare the nature of this invention and in what manuer the same is to be
performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings and to the letters and
figures marked thereon:-
This invention does away with the usual weights for hanging sash windows and

page_text: also the boxing to same. By dividing my window into four, six or any other equal
number of sashes other than two, and arranging them, on pulleys fixed at the top of
the frame and suspending each pair of sashes by chain cord or any other suitable
material. I can if desired have five or a greater unequal number of sashes in the
frame but in as much as the odd one must be fixed I especially name an equal
number of hung sashes.
I will describe my invention as applied to a window divided into four sashes
which is the number I prefer to use although the novel features of my invention
apply to any equal number other than two.
On the accompanying sheet of drawings
Fig. 1 is an elevation of a sash window seen from the inside hung with four
sashes.
Fig. 2 a section of same.
Fig. 3 a front elevation of the pulleys.
Fig. 4 a side elevation of same.
I divide the frame with fillets in the usual way to form four stiles to receive
the sashes a, b, c, d, and fix at the top below the head of the frame one pair of
single pulleys and one pair of double pulleys on each side of the frame, the single
pulleys being placed with the double ones between them. Or I can use only one.
double pulley in the centre as illustrated instead of a pair. I place the bottom
sash a in its usual position on the inner face of the frame and the top sash 6 in its
usual position on the outer face of the frame and connect these sashes by means of
cords or chains passing from one to the other over the single pulleys x, y, using one
pulley of the double intermediate pulleys as a guide. The other two sashes c & d
are connected together by cords or chains over the remaining wheel 21 of the
double pulley. The meeting rails of each sash are rebated in the usual way to:
overlap the adjoining one.
'
To open the window, raise the bottom sash a thus causing the lowering of the top
one b when the centre ones and d will be free to open and the various sashes can
be moved into a variety of positions, and when placed behind one another will allow
of, three fourths of the window to be open instead of the usual one half.
By constructing the window as described any bolt, spring catch, or other device
placed at the bottom of the bottom sash as for instance, at e Figs. 1 & 2 when
fastened will securely prevent the opening of any of the sashes, by reason of the
rebating at ff, f, obliging the raising of the bottom sash to be the first act in
opening the window.. Or the rebates may be dispensed with if the bottom sash a
has a fastening on its top rail attaching it to the bottom rail of, the sash d.
A great advantage gained in hanging the sashes according to this my invention is
that being able to vary the position of each sash to such an extent cleaning the
glass or painting the sashes and frame is much more easily done..
arti
Having now particularly described and ascertained the nature of my said inven-
tion and in what, manner the same is to be performed I declare that what I
claim is :
The improved construction of sash windows as herein described and illustrated
whereby the sashes can be so placed as to enable a greater proportion of the area
of the window to be opened than in an ordinary sash window.
