PROVISIONAL SPECIFICATION.
Improvements in the Construction of the Flooring or Boxings for
Hearths.
I, WILLIAM MOORE, of Mayfield Road, Eccles, in the County of Lancaster,
Builder, do hereby declare the nature of this invention to be as follows:-
The invention is designed to avoid the use of wood in the construction of the
floorings or boxings of hearths for ordinary fire places in dwelling houses or
the like.
Hitherto it has been customary to support the floors of the hearths or hearth
stone upon timber joists or the like but this is objectionable.
This invention consists in constructing the hearth with a flooring or boxing
comprised of a metal plate shaped to be built into the face of the chimney breast
at one end, and extending forward in an arched form with a flange at right angles
in the front by which it is securely attached by screws or bolts to the breast
trimmer.
In carrying out the invention 1 construct a metal plate of cast iron, wrought
iron, steel or brass, shaped with an arch or curve in the centre a flat ledge at one
edge or end which is built into the chimney breast and at the other end a flange is
turned up at right angles or nearly so to stand in a vertical plane. This flange is
made with two or more bolt holes and is by means of coach screw or bolt firmly
attached to the breast trimmer.
The arched form supplies a firm support for the flooring of the hearth either
concrete, stone, flag, tile or other suitable material and it also renders it possible
to lay a piece of wood beneath the boxing to which the ceiling laths below can be
attached.
This boxing is built up with and into the hearth during its construction and the
presence of wood in the floor or under the floor of the hearth is avoided.

COMPLETE SPECIFICATION.
Improvements in the Construction of the Flooring or Boxings for
Hearths.
1. WILLIAM MOORE, of Mayfield Road, Eccles, in the County of Lancaster,
Builder, 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 invention is designed to avoid the use of wood in the construction of the
floorings or boxings of hearths for ordinary fire places in dwelling houses or
the like.
Hitherto it has been customary to support the floors of the hearths or hearth
stone upon timber joists trimmer arches or the like but this is objectionable.

page_text: This invention consists in constructing the hearth with a flooring or boxing
comprised of a metal plate shaped to be built into the face of the chimney breast
at one end and extending forward in an arched form with a flange at right angles
in the front by which it is securely attached by screws or bolts to the breast
trimmer.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Perspective view of sheet steel hearth boxing.
Fig. 2. Perspective view of iron hearth boxing.
Fig. 3. Sectional elevation of hearth showing boxing in position.
Fig. 4. Sectional elevation of modified form of hearth boxing.
I construct the hearth boxing of cast iron, wrought iron, sheet steel or other
metal with an arched or convex plate a in the centre a flat ledge b at the front
which rests upon or is built into the chimney breast B and a vertical flange or back
plate c turned up at right angles or nearly so at the back. The back flange c is
made with two or more bolt holes whereby it is by means of a coach screw c¹ or
bolt firmly attached to the breast trimmer C, or may be extended and hent to rest
upon the top of the breast trimmer.
In the modified form shown in Fig. 4 the arched or convex plate a rests upon
the front plate b which is built into the chimney breast and may be secured by a
bolt or pin passing therethrough.
The arched form of the central plate a supplies a firm support for the flooring of
the hearth A either concrete, stone, flag, tile or other suitable material and it also
renders it possible to lay a piece of wood beneath the boxing to which the ceiling
laths below can be attached.
This boxing obviates the necessity of trimmer arches of brick or stone and is
built up with and into the hearth during its construction and the presence of wood
in the floor or under the floor of the hearth is avoided.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
:-
A hearth boxing constructed with a central arched or convex plate to support
the hearth floor a flat ledge in front to rest on the chimney breast and a vertical
flange or plate at the back to be secured to the breast trimmer substantially as and
for the purpose described.
