A False Bottom for Domestic Fire-grates and other like purposes.
ROBERT BEACOCK, Joiner, 10, Harehills Terrace, Roundhay Road, Leeds, York-
shire, do hereby declare the nature of this invention to be as follows:-
:-
A false bottom for fire-grates composed of loose iron bars-Fig. 1. The
bars--A, B, C, D, are supported by iron plates d³, du Fig. 1, & Fig. 4, having V shaped
grooves as shewn at a, Fig. 4. The bars Fig. 2 are V shaped as in Fig. 3. The
bars having free expansion and contraction ensures that the grate will keep straight
and perfectly horizontal. No bending up or breaking after long exposure to
the fire. The supports Fig. 4 are broader at the base, c, Fig. 5, to allow them
to stand on bottom grate of fire-range. The bars Fig. 2, Fig 3, fit into the
V shaped grooves--a, Fig. 4. The supports can be any distance apart to suit
any fire-range. The bars and the supports can be made to any size to fit into
any fireplace. This grate is adaptable for domestic fire-ranges and the like,
and also as a holder for burning fuel. It is an economizer & it allows an upward
draught.

COMPLETE SPECIFICATION.
A False Bottom for Domestic Fire-grates and other like purposes,
I, ROBERT BEACOCK, Joiner, 10, Harehills Terrace, Roundhay Road, Leeds,
in the County of Yorkshire, 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 consists of the combination of loose iron bars with grooved
supports of iron, together forming a false bottom grate as hereinafter described.
The object of this invention is to ensure the straightness and durability of the
false bottom, when under the heat of the fire usually required for domestic
purposes, and other like conditions.
The invention will be understood by the following description, reference being
had to the accompanying drawings, in which-
Figure 1, is a plan of the false bottom with 4 bars.
Fig. 2, a plan of one of the loose bars.
Fig. 3, a cross section of one of the bars.
Fig. 4, a side elevation of one of the supports.

page_text: Fig. 5, a cross section of one of the supports.
Fig. 6, a side elevation of the bar hereinafter called the key-bar, showing the
projections.
And
Fig. 7, a cross section of end of key-bar, where the projections occur.
Fig. 8, a side elevation of the key-bar in its position, resting in a groove of
the support. Referring to Figure 1, d', ², are the supports, and A, B, C, D,
are the loose bars on which the fuel rests. The supports are provided with
V shaped grooves as shown at a, a', a², a³, Figure 4, the supports may have any
number of grooves to hold the bars, according to width of grate required.
The loose bars, as A, Fig. 2, are V shaped, that is they are tapered in-
wards towards the bottom edge, as shown in section at Figure 3, and they are
like unto this section through all the length of the bar. The bars are slightly
hollow on the top, as shown at e, Fig. 3, this helps to keep them from burning
out so soon. The bars A, B, C, D, Fig. 1, are made, as shown in Fig. 2, and
Fig. 3, and they fit loosely into the V shaped grooves of the supports,-a, a¹, a², a³,
Figure 4, therefore the bars being perfectly loose-thereby having free ex-
pansion and contraction when in the grooves of the supports ensure that they
will have a tendency to keep straight and horizontal, and not to warp or break
with the heat, when used under a fire, as required for domestic purposes and
the like.
The supports are wider at the base, as at C¹, Fig. 5, and C2, C3. Fig. 4, with
flanges on at the bottom to allow them to stand firmly on the bottom grate of
fireranges. I may make these flanges any width or size according to requirements.
The supports may be placed any distance apart to suit any fire-grate or fire-
range. The bars may over-lap or project over the supports at each end, as
shown at H, H', Fig. 1, and H', Fig. 8, and to provide for this I make one of
the bars for each grate with two projections about one inch or more from each
end, and underneath, as shown at E, E, and E³, E4, Fig. 6, and E³, Fig. 7, also
E, E, Fig. 8. I call this the key-bar, its purpose is to show where to place the
supports, so as to allow the ends of the bars to over-lap or stand past the supports,
as shown at H, and H2 Fig. 6, and H¹, Fig. 8, it also helps to keep the false
bottom firm. Looseness or space is also allowed between these two projections
on the key-bar for expansion etc., as shown at F¹, and F2, Fig. 8. I wish it to
be understood that I may make this false bottom grate (according to my
invention) with or without the aforesaid key-bar for all or any of the bars forming
the grate, and that I may substitute in place of the aforesaid key-bar one of
the other loose bars which are without the projections, as herein-before described.
Furthermore that I may make the false bottom grates of various widths and
lengths, that is, I may make and form them with any number of loose bars,
the bars being longer or shorter, as may be required, also I may make the bars
any length and any strength or thickness of metal, so as to allow them to be
used to advantage under the various degrees of heat required in fireranges and
fire-grates for domestic purposes and under like conditions, and I may also make
and use different lengths of bars in one and the same complete false bottom.
grate, so as to fit any shape of fire-grate or firerange.
The supports may be made of any thickness of metal, or any width, or any
height, to suit requirements, and the said supports provided with grooves for
holding the bars may be made any shape, so as to take over or engage with any
suitable part of fireranges, or fire-grates. All the parts of this invention must
be made of hard fire-bar metal, so as to give the best results in regard to dur-
ability and in accordance with the object of this invention.
This false bottom, as herein-before described is formed and placed in the fire-
place by first standing the two supports on the real bottom grate of the fire-
range, one support at each end, and then placing the loose bars in the grooves
of the supports. It is then ready for use. It is easily placed in position and
easily removed. If the aforesaid key-bar is used in the grate it should be used
as the centre bar, or one of the middle bars of the grate.

page_text: False bottom grates made according to my invention will last longer, are
cleaner, and will remain straighter than those at present known and in use.
It is applicable for domestic fire-grates, and other like purposes, also, as a
holder for burning fuel, as an economizer of fuel, and it allows a clear upward
draught to the fire.
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
1. A combination of loose iron bars and grooved iron supports which when
placed together as herein shown and described forms a false bottom grate, for
domestic fire-grates, fireranges and other like purposes, as substantially described
and set forth.
2. A false bottom grate of any size or shape, with any number of loose iron
bars, resting in grooved iron supports, as herein particularly described, and for
the purposes set forth.
3. In connection with my said invention the loose supports of any required
shape or size, provided with grooves for holding any number of bars to form
a false bottom grate, as substantially described and set forth.
4. A false bottom grate formed with any length of bar, or with different
lengths of bars in the one and the same grate, and with bars of any strength
or thickness of metal, all being loose bars and fitting into grooved supports
for the purposes described and particularly set forth.
5. In combination with the loose bars and the grooved supports, a key-bar
having two projections underneath at each end, to form one of the bars or all
or any of the bars of the false bottom grate for the purposes described and
particularly set forth.
6. In connection with fire-grates and fireranges, a grate formed of loose and
detachable bars fitting into grooved supports of any shape or size, to take over
or engage with any suitable part of fireranges or firegrates, with or without
the projections underneath at end of the bars, as herein-before described. For
domestic and other like purposes, as herein substantially described and set forth.
Dated this 3rd day of July 1899.
