IMPROVEMENTS IN AND RELATING TO WINDOW SASHES
Year: 1884

page_text: JOHN CARTER, Agent 66 Beaufort Street Chelsea London S.W. do hereby declare
the nature of my Invention for IMPROVEMENTS IN AND RELATING TO WINDOW
SASHES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
I fix a pulley on each side of the window frame at the top in 'window 1 (1') of the
Drawing or preferably inside at the lateral and upper part of the window frame
as in window 2 (2) over which I pass my suspending chain, band, or cord, one end
of which I attach to each sash at the lateral and upper part, preferably to the
inner side, by means of a hook and rack, or preferably hook and staple, in groove,
having additional holes for shifting the staple, to shorten the suspending medium,
should it stretch. The whole of the chain, cord or band and pulleys can be
completely out of sight. By the above it will be understood that one sash counter-
balances the other. On the outer sash, inside, and in the middle, I fix an eye for
the attachment of a line to pull the top sash down, window 1 (3') the bottom sash
will be pulled up at the same time.

I close the window by pulling down the bottom sash, which will at the same
time close the upper sash. On the top of inner sash is one or two bolts, to secure
the window whether open or shut, the bolts bolt into the window frame, one on
either side, window 1-4.' The sashes are placed in the frame in the usual way,
with the exception of the middle bead and inner bead, which I put on in three
pieces, the top and bottom pieces I nail on. The centre pieces of inner beading
I fix on with two thumb screws, having wide base to support the sash 5. For
heavy sashes I put a foot to the thumb screws, '6,' and also two plugs, one at each
end 7' which fit into corresponding holes in the frame, in addition to the thumb
screws, so that they can support a sash of any weight. The centre pieces of middle
beading I cut at the top sloping downwards, to fit under its fellow. To take out
the sash, I open the window, window 2' and remove the thumb screws and feet,
and screw them under the sashes, into the holes, 'window 2-8 unhook the line,
band, or chain, and the inner sash can be removed, to take out the outer sash
I remove the middle pieces of beading, and the sash can be removed for cleaning,
or passing large pieces of furniture in or out of the window &c. The hooks have
a cross piece on them to prevent them slipping through the pulley '9.' By the
afore written description it will be observed in that there are only two pulleys

page_text: instead of four in the usual way. That only one quarter of the usual quantity of
chain band or cord is required. That the usual iron weights are dispensed with.
That there are not any boxes required to the frames, which will be less expensive
to make, and stronger. That there will not be any draught at the bottom of the
window, and complete ventilation, as the draught of fresh air will come in at the
top, and the impure air will pass out at the bottom, if the room door is shut.
That the window can be opened or shut at any height, by the cords as fastened to
the sashes, 'window 1.' That the window may be fixed at any given opening
securely against thieves, if not open too wide.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1 The arrangement for suspending window sashes by pulleys staple and hooks
substantially as herein before described and illustrated in the accompanying
Drawings.
2nd The method of balancing the sashes one against the other, by chain hooks
and staples, without weights, substantially as herebefore described and illustrated
in the accompanying Drawings.
3rd Securing the sashes open or shut by a bolt in the manner herein before
described.
4th The use of a moveable piece of beading fixed in position by thumb screws
for the purpose herein before set forth and described.
5th The use of a hook_constructed as herein before described for fastening a chain
band or cord to the window sash with staple.
6th The use of the thumb screws constructed as herein before described for
supporting the sashes when detached from the chain, band, or cord, for the purpose
of removing the sashes.
