Improvements in Fire Grates.
1, WILLIAM GREIG BANNOCHIE of 17ª Belmont Street, Aberdeen, in the
County of Aberdeen, North Britain, Plasterer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a contracting and adjustable grate.
The sides of the grate at fire box are of fire brick in metal cases and being
attached to the bottom of the grating are moveable and adjustable in such a way
that by pulling the sides towards the centre of the grate and pulling forward the
bottom grating, the whole fire brick is contracted, thus forming a contracting and
adjustable grate.

Improvements in Fire Grates.
I, WILLIAM GREIG BANNOCHIE, of 17ª Belmont Street, Aberdeen, in the
County of Aberdeen, North Britain, Plasterer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :-
This invention relates to improvements in fire grates, and has for its object to so
arrange and construct a fire grate that it will be capable of being collapsed and
adjusted so as to economise the use of coal during consumption.
In carrying out my said invention,
form the sides and the back of the fire box
as movable metal cases into which fire bricks are placed.
But in order that my said invention may be more readily understood and easily
carried into effect, I will proceed to describe the same with reference to the
accompanying drawings.
Figure 1 is a plan of my improved grate, having its top plate removed.
Figure 2 is a cross section on line X, X Figure 1.
And Figure 3 is a part longitudinal section on line Y, Y Figure 1.
Referring to the said drawings I form each of the two sides as metal cases A
and fill them in with fire brick B; the said cases A are each connected to the
framework C of the grate, by means of an upper and lower button or pivot D, in
such a manner that they can be swung in towards the centre of the grate, and so
contract the opening of the fire box, there being snugs E having holes or openings e
into which a poker or rod may be inserted so as to move them. The sides are
prevented from going too far in by means of the projections or stops F formed on
or attached to the front bars G of the grate.
The bottom grating H with its metal and fire brick back J is also capable of
being adjusted to or from the front bars G, there being suitable guides ; and
snug with hole or opening provided for this purpose.
The whole arrangement thus forms an adjustable and collapsible grate in which
the sides and back may be contracted inwards or expanded outwards, during the
burning of the fuel, so as give a larger or smaller box opening as desired; this
movement being facilitated by means of forming the under portion of the fire box
LD011

page_text: with a number of perforations or openings K so as to allow any surplus ashes to
drop through, and prevent any tendency of the said ashes from accumulating and
so form an impediment to the working of the said parts.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
:-
1st. The general arrangement, construction and combination of the various parts,
constituting my improvements in fire grates, substantially as herein before described
and shown in the accompanying drawings.
2nd. In fire grates, the moveable metal and firebrick sides, substantially as and
for the purposes herein before described and shown in the accompanying drawings.
3rd. In fire grates, the moveable bottom grating having metal and firebrick back,
substantially as and for the purposes herein before described and shown in the
accompanying drawings.
