Improvements in Apparatus for Facilitating the Opening and
Closing of Windows.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to an attachment to the upper sash of a window, by means of
which such sash can be readily lowered and raised, and the means for, so operating
the sash will when not in use swing out of the way of the lower sash in raising and
lowering the lower sash. In other words this attachment' is arranged within the
styles of the sash so that it lies against the style and flush with the surface of the
window frame.
In the accompanying drawing,
Figure 1 represents a front elevation of a window, to the upper sash of which my
invention is applied.
Figure 1 is a front elevation of a window showing a modification of my invention.
Figure 2 is a cross section of the window taken on the line x, x of Figure 1*
showing the attachment on one side of the window.
Figure 3 is a cross sectional view of an enlargement of one of the upper corners of
the lower sash as shown in Figures 1 and 1*.
Figure 4 is an enlarged detached view of one of the upper corners of the upper
sash.
Figure 5 is a front view of one of the swinging bars.
Figure 6 is a side view of the same.
a, a are two bars, one on each side of the window resting closely against the angle
formed by the pane of glass and one of the vertical styles of the window frame.

Inserted in the top of this bar is a screw èyè b having its eye opened in the shape of
a hook, so as to hook into another screw eye c which is inserted into the style d of the
upper sash. These bars a, a are long enough to swing within the horizontal styles of
the upper sash and they are loosely secured within the styles and flush with the
surfaces of same, so that in the movement of the window sashes up and down they
will be entirely out of the way. These bars can also be made to closely resemble the
styles both in colour and in moulding, so that they will not be noticed by the ordinary
observer, casually looking at the window.
The operation of these bars is as follows: When it is desired to pull down the
upper sash the bars are pulled forward and downwards, one in each hand. By
pushing up the bars the sash is moved up into place again, and the bars then swing in
against the window pane and flush with the outer surface of the window styles so that
free movement can be given to the lower sash up and down in order to wash the
windows &c. with the same ease as if no sash moving attachment was on the window.
In Figure 2 the.dotted. lines represent one of these bars, as pulled, forward by the
hand just at the commencement of the operation to pull down the upper sash.
With this operation and arrangement of the parts a heavy window is very easily
handled, and at the same time the attachment can be readily detached from the sash.
It is so arranged as to be like a part of the styles themselves, and is scarcely noticed.
There can be an enlargement e (Figures 1 to 6) on the lower end of each of these
hars a, a for a short distance from their lower ends. The enlargement projects out
for a sufficient distance so as to impinge upon the top of the horizontal style of the
lower sash in case such sash is attempted to be pushed upwards from the outside, so
that no movement can take place in the two sashes unless these bars are pulled
forward, which position, they would be in, in case it was desired to pull down the
upper sash. The bars a, a, thus serve for the purpose of pulling down the upper sash
and they also serve as a substitute for a sash lock, or will supplement the ordinary
sash lock. By reason of this construction and arrangement of the parts the bars a, a
autoniatically lock by falling into place; unlike prior devices, which latter have
either to be shifted into place,, or locked into place, by the aid of additional elements.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my foreign
Correspondent, I declare that what I claim is:-
TIN
First The swinging window bars a, a provided at their ends with screw, eyes b; b
in combination with screw eyes c, e inserted in the styles.d, d of the upper sash and
so constructed, that such bars are brought flush with the surface of the upper sush,
and one sash may be passed freely over the other one substantially as described.
Second-The swinging window bars a, a loosely secured to, and having screw
eyes, near the top of, the sash so as to serve for pulling it up and down, constructed
with enlargements se, at their lower ends to lock over the lower sash in order to
prevent it from being raised, substantially as described.
