An Appliance for Opening and Closing Top Sashes of Windows and
for Locking both Top and Bottom Sash either in a Closed or
Partially Opened Position from the Top or from the Bottom.
I, WILLIAM SPEIRS SIMPSON, of Battersea Park Road, Surrey, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
The object of this invention, is to fit an appliance to the top sash of a window, part
of which appliance can be shifted from the side to the centre of the top rail, for
pulling said top sash down for ventilation, or other purpose and for pushing said
top sash up for closing the same. This part of the appliance is of such a length as
when slid to the side rail, to rest upon, or nearly upon the top rail of the lower sash
and so lock the two sashes, to prevent them, or either of them being opened from
the outside. This part of the appliance, has preferably a handle to facilitate its easy
manipulation, and said handle, or its equivalent is notched, or otherwise shaped, to fall
against the top rail of the lower sash, when the top sash is lowered, or the bottom sash
raised, and lock the two sashes in that position. The degree of opening of either
sash will be limited by the length of the handle, or its equivalent, or by the notches
thereon, both sashes being securely locked. The sashes, or either of them may have
any further movement imparted to them in the usual manner for cleaning, or other
purposes.
The other part of the appliance, is a bar, or rod attached to, but standing out from
the top rail of the upper sash and its length determines the motion of the first
mentioned appliance which is fitted to slide thereon.

An Appliance for Opening and Closing Top Sashes of Windows and
for Locking both Top and Bottom Sash either in a Closed or
Partially Opened Position from the Top or from the Bottom.
I WILLIAM SPEIRS SIMPSON of Battersea Park Road, Surrey Civil Engineer, do
hereby declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement :-
The object of this invention is to fit an appliance to the top sash of a window part 5
of which appliance can be shifted from the side to the centre of the top rail, for pulling
said top sash down for ventilation or other purpose and for pushing said top sash up
for closing the same. This part of the appliance is of such a length as when slid to
the side rail, to rest upon or nearly upon the top rail of the lower sash and so
lock the two sashes to prevent them or either of them being opened from the outside.
This part of the appliance has preferably a handle to facilitate its easy manipulation
and said handle or its equivalent is notched or otherwise shaped to fall against the top
rail of the lower sash, when the top sash is lowered or the bottom sash raised, and lock
the two sashes in that position. The degree of opening of either sash will be limited
by the length of the handle or its equivalent or by the notches thereon, both sashes
being securely locked.
The sashes or either of them may have any further movement imparted to them in
the usual manner for cleaning or other purposes. The other part of the appliance is a
bar or rod attached to but standing out from the top rail of the upper sash and its
length determines the motion of the first mentioned appliance which is fitted to slide-
thereon.
The invention will be understood by the annexed drawings as applied to window
sashes as at Figures 1 and 2.
A is the bar by which the top sash B can be lifted, said bar being hung from a
horizontal bar which is of such a length that the bar A may be shifted along by
hand to say the centre of the window as seen in Figure 2 for raising or lowering the
upper sash B by hand. Said bar A is of such a length that when the two sashes B. D.
are closed its lower end rests upon the top rail E of the lower sash D as seen in
Figure 1 and locks both sashes B, D, in a closed position but by shifting the bar A
along the bar C as seen at Figure 2, the upper sash can be pulled down from its
centre part so that it comes down evenly, but said sash B may be pulled down when
the bar A is at the side by simply pulling the handle F from contact with the top
rail E of the lower sash D and then by dropping one of the notches G of the bar A
on to the top rail E of the lower sash D the two sashes B D become locked with the
upper one B open for ventilation or other purpose,

page_text: I have spoken of rods or bars A and C but I may dispense with the bar A and put
another horizontal bar C¹ corresponding to C on the top plate H of sash frame I over
which bar Ca cord connected to a runner on the bar C can be shifted along as before
explained with reference to the bar A so that the upper sash B can be lowered by a
pull on the cord J and be raised by a pull on the cord K said cords J K being fixable
by a twist round a "Young" or other fastener L on the sash frame I but by placing
another "Youngs" fastener on the lower sash and whipping the double cord round it
the lower sash will be locked also.
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
The bar A or its equivalent movable along a bar C as hereinbefore described for
opening or closing the top sash B of a window also for locking the top or the bottom
sash or both top and bottom sashes either in an opened or partially opened or a closed
position as set forth.
