An Invention for Securing the Thorough Ventilation of Rooms
Lighted by Ordinary Lifting Sash Windows.
JOSEPH PHILIP WILSON Builder White Abbey Road Bradford, Yorks, do hereby
declare the nature of this invention to be as follows :-
In order to carry out the above declaration I propose to hang ordinary lifting
sashes in such a manner that by lifting the bottom sash to any height the top sash
will simultaneously lower itself the same distance, this movement to be effected by
balancing the sashes on two cords, one to each side of the window, one end of each
cord being attached to the edges of the bottom sash in the usual way & the other.
ends similarly fixed to the top sash, the cords meanwhile passing over two pullies
fixed in the head or transom of the window frame & close to what is known in
ordinary sash windows as the pulley stiles. A regulator would be fixed to one end of
each cord to rectify any stretching of the cords. By this invention the ordinary sash
weights are dispensed with.

Lighted by Ordinary Lifting Sash Windows.
I JOSEPH PHILIP WILSON of White Abbey Road, Bradford in the County of
York Builder do hereby declare the nature of this Invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
In order to carry out the above declaration I propose to hang ordinary lifting sashes
in such a manner, that by lifting the bottom sash to any required height, the top sash
will simultaneously lower itself the same distance, this movement to be effected by
balancing the sashes on cords or chains one to each side of the window, one end of
each cord being attached to the edges of the bottom sash in the usual way and the
other ends similarly fixed to the top sash the cords meanwhile passing over two
pulleys in the head or transom of the window frames and close to what is known in
ordinary sash windows as the pulley stiles, a regulator would be fixed to one end of
each cord, to rectify any stretching of the cords. By this invention the ordinary sash
weights are dispensed with.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a side elevation in section of windows hung according to my invention.
Fig. 2 is a front elevation of Fig. 1.
Fig. 3 is a full sized view of pulley and its hanger or bracket.
A are the pulleys carried in their hangers B, which are so formed that they can be
fixed by screws or otherwise in the head of the window frame C, and taken off without
disturbing the frames C, or other fittings; it being unnecessary to open the frames C
or pulley stiles; also the pulley hangers or brackets B strengthen the frames; I
prefer to use copper wire cords or chains D which are secured to the sashes by hooked
screws E, and regulating nuts F for tightening the cords or chains when required,
grooves are formed in the sash frames to clear the cords or chains, the cords or chains
after being secured to one sash pass over the pulleys to the other sash, to which they
are secured, thus balancing the windows and dispensing with weights, and on raising
the bottom sash, the top sash will lower simultaneously, thus effective and complete
ventilation is secured.

page_text: Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :-
1. The arrangement of balanced sliding windows, whereby weights are dispensed
with and thorough ventilation is insured, substantially as shown and described.
.
2. The arrangement and construction of the pulley hangers or brackets, substantially
as shown and described.
3. Regulating the adjustment of the cords or chains, substantially as shown and
described.
