Improvements in and connected with Window-frames. O
I WILLIAM ALLEN, of Glenryn, Walpole Road, Boscombe, Bournemouth, in the
County of Hampshire, Gentleman, 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 :—
The object of the present invention is to provide a window-frame the sashes of
which instead of being suspended in vertical grooves as heretofore, are hinged
to the framework at their lower extremities so that when opened they incline
inwardly.
When it is desired to open these sashes to a small extent, say for purposes of
ventilation, they are held in position by means of suitable spring controlled snaps
or latches which are fixed in the sides or the top of the said sashes, and caused to
engage with the recesses of a rack-bar let into the frame, or the recess in an ordinary
striking-plate. These snaps may be operated directly by hand, or by means of
cords. If however it is desired to open the sashes to a greater extent, metal arms.
are provided, which are pivotally connected to the sashes at one end and pass
through eyes mounted on the sides of the frame-work, and have their free ends bent.
so as to form stops. For the purpose of preventing dust and other foreign matter
being carried into the room when the sashes are opened for ventilation, I provide a
detachable guard composed of any suitable gauze and held by means of spring clips.
between the tops of the sashes and the frame-work.
Referring to the accompanying drawings―
Fig. 1. shows a section of my improved window-frame and sashes, and
Fig. 2 a back elevation of the same.
A is the frame-work, to a cross bar of which is hinged the sash B, and to the-
lower portion the sash B'.
The sash B is shown open to its full extent and held in position by arms b
pivoted at baud passing through eyes 6'. The sash B is held in position by the
snaps C which are engaged with recesses d in the bars D on either side of the
frame. A recess is shown at a for engaging a snap fixed on the upper side of
the sash. E represents a dust-guard, and F, F, are spring clips for rigidly
attaching it to the cross bar of the frame and the sash respectively.
It will be readily understood from this description that the outsides of the-
window-panes can be cleaned without any personal risk.
Having now particularly described and ascertained the nature of my said invén-
tion, and in what manner the same is to be performed, I declare that what
I claim is-
1. The construction of window-frames with sashes such as B, B', hinged thereto.
and capable of being held in position when open by means of snaps or latches C
engaging with recesses either in the frame-work or in rack bars fixed thereon, and
by means of metal arms such as b substantially as herein described and illustrated.
on the accompanying drawings.
2. The combination with window-frames and sashes such as B, B', with a dust.
guard such as E substantially as herein described and illustrated on the accom-
panying drawings.
