PROVISIONAL SPECIFICATION.
Improvements in and relating to Cheeks of Hopper Windows.
We, CHARLES CHIDLEY MALLETT, Engineer, and MARY HANNAH MALLETT,
Widow, both of Shorne Cottage, Southend-on-Sea, in the County of Essex, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in cheeks for use with hopper windows
and has for its object the provision of cheeks so constructed that the flange
against which the sash rests when open can be moved aside to enable the sash
to pass the cheek and be lowered to any desired angle and thus facilitate the
cleaning or repairing of the outside of the window. In carrying our invention
into effect we hinge the moveable flange to the frame of the cheek in such
a manner that it can be moved endwise along the pin or rod of the hinge and on
the frame of the cheek we provide stops with which the moveable Hauge engages
when in its normal position and is thereby prevented from turning. When it is
desired to lower the sash the moveable flange is moved along the pin of the
hinge until it is clear of the stops on the frame of the cheek when it can be
turned aside. We can also when desired provide our cheeks with rests to sup-
port the sash while being cleaned and repaired.
Dated this Ninth day of November 1899.

Improvements in and relating to Cheeks of Hopper Windows.
WC, CHARLES MURRAY FORD, of 6 and 7, Cross Lane, Eastcheap, in the City
of London, Tea Merchant, Executor of the late Charles Chidley Mallett, and
MARY HANNAH MALLETT, Widow, of Shorne Cottage, Southend-on-Sea, in the
County of Essex, 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 improvements in cheeks for use with hopper windows
or fanlights and has for its object the provision of cheeks so constructed that
the flange against which the sash rests when open can be moved aside to enable
the sash to pass the check and be lowered to any desired angle and thus facilitate
the cleaning of the outside of the window or fanlight, or painting or repairing
of the same. In carrying the invention into effect, the movable flange is hinged

page_text: to the frame of the check in such a manner that it can be moved endwise along
the pin or rod of the hinge, and on the frame of the cheek stops are provided
with which the movable flange engages when in its normal position and is
thereby prevented from turning. When it is desired to lower the sash, the
movable Hange is moved along the pin of the linge until it is clear of the stops
on the frame of the cheek when it can be turned aside.
When desired, the improved cheeks can also be provided with rests as herein-
after described to support the sash while the same is being cleaned and repaired.
In the accompanying drawing, we have shown how the said invention can be
conveniently and advantageously carried into practice:-
Figure 1 is a side elevation, of our improved cheek or side frame for hopper
windows or fanlights, the flange being in the normal position.
Figure 2 is a transverse section on the line A-B, Figure 1, drawn to au
enlarged scale,
Figure 3 is a side elevation of the same showing the flange open to permit
lowering of the sash, and
Figure 4 is a transverse section on the line C-D, Figure 3, drawn to an
enlarged scale.
Like letters of reference indicate corresponding parts throughout the drawing.
a is one of the two cheeks or side frames of a hopper-window or fanlight,
between which cheeks there moves a sash turning about a hinge or hinges at
its lower edge in the usual manner. The side cheeks are glazed, and fixed to
the stationary framework in the usual manner.
On the outer edge of each of the checks a, is a hinged flange c, carried by a
longitudinal hinge pin d, or by two such pins, one at each end of the flange.
The knuckles e on the cheeks a carrying the hinge pins are separated sufficiently
to permit the knuckles f on the flanges to slide longitudinally through a dis-
tance preferably slightly greater than the length of the knuckles f. The said
knuckles are provided on their outer edges with stops g which, when the
flange is in the position shown in Figures 1 and 2, engage with stops h, h on
the cheek a and retain the said flange in this position.
As
When, however, it is desired to lower the sash 6 for cleaning or other purposes,
the flange c, of each check is moved to the uppermost limit of its travel along
the pin d, in which position the stops 7 clear the stops h, and the flanges c
can then be turned outwards so as to enable the sash b to pass out from between
the chocks a, a and be lowered into a convenient position for cleaning, etc.
the flanges c, c are turned outwards, as above described, the ends of the stops g,
come into engagement with each other and retain the flanges in their elevated
positions. By turning the flange in again and then lowering the same it
becomes locked by re-engagement of the faces of the stops g, h. A handle j, is
provided on each flange c, whereby the said flange can be conveniently raised and
lowered as above described.
h
Pivoted to the inner side of ench check is a hooked rest or support adapted
to swing upwards and be retained in that position by the flange c. When, Low-
ever, the said flange is turned outward, the rest is released and falls down to
receive the sash band to hold it in a convenient position for cleaning or repair.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. For a hopper window or fanlight, a cheek or side frame provided with
a flange which acts in one position as a rest for the sash, and which can be
moved longitudinally on its hinge pin into another position where it can turn
to allow the sash to pass, substantially as described.
2. The construction of the cheek or side frame and hinged flange substantially
as described and illustrated, for the purpose specified.
3. The combination, with a cheek or side frame provided with a hinged flange,

page_text: of a pivoted hook or rest to form a support for the sash when the latter is
lowered for cleaning or other purposes, said hook or rest being arranged in
relation to the hinged flange, substantially as described.
