PROVISIONAL SPECIFICATION.
Improvements in and connected with Wash Boller and similar
Fire-doors.
I, MARY SIBBRING, of 1, White Rock Street, Liverpool, Married Woman,
do hereby declare the nature of the said invention to be as follows:-
This invention relates to fire doors which are hinged to iron casements or frames
which are built in brickwork, such as domestic wash boiler doors, stove doors, and
similar doors; the invention also relates to said casements or frames.
At present such doors are hinged to their casements or frames by means of pins
which pass through lugs formed on the door and casement respectively, and it is
found that sucb pins quickly become rusted or worn away. Owing to the casement
being built up in overhanging brickwork it is impossible in many cases to replace
such pins, and one of the objects of the present invention is to obviate this
difficulty.
According to this invention wash-boiler and similar fire doors are cast or formed
with pintles or hinge pins thereon. The frame or casement for said door is
preferably of cast metal, and in casting the same the door is laid in the mould so
that when the metal is run in lugs are formed on the casement which surround the
pintles on the door.
My invention also relates to an improved formation of the frame or casement
above referred to, with the object of rendering them more firm or stable in their
surrounding brickwork. For this purpose provide the rear of the casement with
flanges which are adapted to abut against the rear of the bricks which surround
the casement. I also prefer to form the upper side of the casement somewhat
wider than at present and so render unnecessary the arch-bar which is now
commonly fitted to support the brickwork.

Improvements in and connected with Wash Boiler and similar
Fire-doors.
I, MARY SIBBRING, of 1, White Rock Street, Liverpool, Married Woman,
do hereby declare the nature of the said 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 casement fire doors which are built in brickwork, such
as domestic wash-boiler doors, stove doors, and similar doors; and also to the
construction of said casements.
At present such doors are hinged to their casements or frames by means of pins
which pass through lugs formed on the door and casement respectively, and it is

page_text: found that such pins quickly become burnt or worn away; and owing to the
casement being built up in overhanging brickwork it is impossible in many cases
to replace such pins, and one of the objects of the present invention is to obviate
this objection.
In the drawing hereto annexed Figure 1 shews my improved method of hinging
fire doors to their casements. The fire door a is cast or formed with pintles b
thereon. The frame or casement c for said door is of cast metal, and in casting
the same the door is laid in the mould so that when the metal is run in, lugs d are
formed on the casement which surround the pintles on the door.
My invention also relates to an improved formation of the frame or casement
above referred to, with the object of rendering it more firm or stable in its
surrounding brickwork. Such formation is shewn in Figure 2 (front view) and
Figure 3 (end view), and consists in providing the rear of the casement with
flanges e adapted to abut against the rear of the bricks that are built around the
casement. I also form the upper side or mantel f of the casement c considerably
wider than at present and so render unnecessary the employment of an arch-bar
which is now commonly fitted to support the brickwork.
In some cases I form both the upper and lower sides of the casement c with the
increased width, in order that the casement may be reversible. for right and left
hand fire places respectively.
It will be understood that the method of hinging doors to the improved casements
above described need not necessarily be according to that described with reference
to Figure 1, but may be as shewn in Figures 2 and 3, or otherwise.
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. The combination with a fire door, of the type above referred to, having hinge.
pintles formed thereon, of a casement which in the process of casting has formed
upon it lugs which bold said pintles, flanges adapted to lie at the rear of the bricks
in which said casement is built, and an extended mantel for supporting such
brickwork, substantially as described.
2. A fire door casement provided with flanges adapted to lie at the rear of the
bricks in which said casement is built and with or without an extended mantel for
supporting the upper part of such brickwork, substantially as described.
3. A fire door casement provided with an, extended mantel for supporting the
bricks lying on such casement, and with or without flanges adapted to lie at the
rear of the bricks in which said casement is built, substantially as described.
