PROVISIONAL SPECIFICATION.
Improvements in Cheeks of Hopper Windows.
I WILLIAM YOULTEN, of 159 Victoria Street, Westminster in the County of
London, Architect, do hereby declare the nature of this invention to be as
follows:-
According to this invention, instead of the usual 1 or other section, customarily
employed for the purpose of receiving the glass, on one flange, and the hopper
window, when open, on the other flange, I provide a piece of bar iron of a suitable
cross section for the purpose of receiving the hopper, when open, so attached to a
piece of iron, or other suitable cross section designed to receive the glass, that
the former may be temporarily folded or moved aside to allow the hopper window
to completely pass the cheeks, and be lowered to any desired angle for the purpose
of cleaning or repairing the outside of the said hopper window.
I also provide a button or other suitable device to one or both cheeks in order
to form an automatic stop as a safeguard against accident, in case after returning
the hopper to its closed position the cleaner should fail to unfold or slide back into
its normal position the bar previously described as attached to the section of the
wing which holds the glass.
I further provide suitable fittings to the window frame and the hopper sash for
the purpose of attaching thereto any suitable temporary hopper window hold-fast
whilst the cleaning is in progress.

I WILLIAM YOULTEN, of 159 Victoria Street, Westminster in the County of
London, Architect, 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 :-
· According to this invention, instead of the usual 1 or other section, customarily
employed for the purpose of receiving the glass on one flange and the hopper
window, when open, on the other flange, I provide to each cheek a piece of bar
iron, of a. suitable shape in cross section, for the purpose of receiving the hopper
when open, so attached to a piece of L iron, or other suitable cross section
designed to receive the glass, that the former may be temporarily folded or moved
aside to allow the hopper window to completely pass the cheeks and be lowered to
any desired angle for the purpose of cleaning or repairing the outside of the said.
hopper window.
I also provide a button or other suitable device to one or both cheeks, in order
to form an automatic stop as a safeguard against accident, in case, after returning.
the hopper to its closed position, the cleaner should fail to unfold or slide back into

page_text: its normal position the bar previously described, as attached to the section of the
wing which holds the glass.
I further provide suitable fittings to the window frame and the hopper sash, for
the purpose of attaching thereto any suitable temporary hopper window hold-fast,
whilst the cleaning is in progress.
And in order that my said invention may be more clearly understood, I will now
proceed to describe the same with reference to the drawings accompanying this
specification, in which
Figure 1 shews side elevation of the hopper cheek,
Fig. 2 shews a front elevation of movable face bar bereinafter referred to,
Fig. 3 is a plan of left hand side of cheek, shewing fanlight passing the cheeks
for cleaning purposes,
Fig. 4 is a plan of one of the cheeks (left hand side one) shewing fanlight"
resting on the movable bar, hereafter referred to, when the former is opened for
ventilation to its full extent, (see also Fig. 1),
Figure 5 is a plan of mullion hopper cheek,
Fig. 6 elevation of mullion hopper cheek safety catch, of which there are two,
one on each cheek,
Figure 7 shews detail hereafter referred to, drawn to a smaller scale.
The same letters of reference are employed to denote the same parts in all the
views.
a shews hopper cheek, b shews piece of bar iron, attached to a piece of L iron c,
designed to receive the glass. The piece of iron b has two slots d d therein,
into which pins e e fixed to the L iron c take, f shews a button, pivotted to the
bar b at g.
When it is desired to open the window for ventilation, the bars b, should be in
the position shewn at Figs. 2 and 4, and are retained in such position by means of.
the pins e taking into the slots d, by which the bars 6 will form a flange inside each
of the hopper cheeks, for the window to rest against, and when it is required to
turn the window completely down for cleaning purposes, the bars b are moved
back, so that the window clears the cheeks, and the bars are kept in this position
by means of the slots d and the pins e (Fig. 3).
The button forms an automatic stop and is provided as a safeguard to prevent
accident by the window falling down clear of the hopper cheeks, should the bars b
not have been placed in position as aforesaid through oversight.
h
i is a ring of any ordinary spring catch, used for securing the fanlight / to the
frame, k denotes spring ball catch, which projects from each side of the fanlight so
that when the latter is being opened for purposes of ventilation it enters either of
the holes formed for its reception.
Instead of having the bars 6 to move on the angle iron as shewn, I may have
them hinged to the latter, an example of this is shewn at Figure 7, in which the
bars b are hinged on to the cheeks at m and are kept in position by the spring
catch n.
The mullion hopper cheek is fitted on the same principle as aforesaid.
.. Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In cheeks of hopper windows, the employment of pieces of bar iron for the
purpose of receiving the hopper when open, so attached to pieces of iron-of such
shape in cross section as to receive the glass--that the pieces of bar iron may be
temporarily folded or moved aside to allow the hopper window to completely pass
the cheeks and be lowered to any desired angle, for the purposes of cleaning or
repairing the outside of the said hopper window.
2. In improvements in cheeks of hopper windows-such as those claimed in the
preceding claim-the employment of an automatic stop, for the purpose set
forth.

purposes set forth.
