PRUVIDIONAL SPECIFICATIVA.
Improvements in Fireplaces, Furnaces, and the like.
JOHN DANIEL WOOD, Elmwood, Warlingham, Surveyor, do hereby declare the.
nature of this invention to be as follows:--
A device for use in connection with domestic fireplaces, furnaces, and the
like whereby heated air is conveyed into the fire causing the perfect combustion
of the fuel and the smoke. and other products emanating from the combustion
thereof. The device consists in a slab or block of iron, fireclay, asbestos or
other suitable material in which a tunnel or passage is formed. The tunnel or
passage may take the form of a groove formed in either the whole or a portion
of the underside of the block, or it may be a distinct perforation through the
whole or a portion of the block. The tunnel or passage may be in either case of
any shape, and may be irregular in either size shape or course, singularly and
collectively. There may be any desired number of like or unlike tunnels or
passages in each block, and these may or may not be connected by one or
more like or unlike transverse or oblique tunnels or passages. The block may
be of any desired shape or size. It is intended that one or more of the said
blocks should be placed in the firegrate, furnace or the like in such a manner
that the course of the tunnel or passage should be from front or sides or back of
the firegrate furnace or the like to the interior of the same, or from one or
more of these directions.
One or more of like or unlike blocks may be used in one firegrate furnace
or the like. The blocks are placed on and cover the whole or a portion of the
bottom of the firegrate furnace or the like so that the blocks are covered by
the fuel. One or more of the blocks may however take the place of the bottom
of the firegrate, furnace or the like, or a portion thereof.
Improvements in Fireplaces, Furnaces, and the like.
JOHN DANIEL WOOD, of Elinwood, Warlingham, Surveyor, 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 a block which may be used either in a firegrate,
stove, cooking range, furnace or the like or on a flat surface such as a hearth,
and has for its object to enable the air admitted to the glowing fuel to become
very highly heated before reaching the fuel. By these means I am able to
Price ed11

page_text: secure almost perfect combustion and adapt ordinary firegrates for burning
coke, anthracite, and other hard coal, though softer coal and other fuel may
be used.
The invention will be best understood by reference to the accompanying
drawings.
Like letters indicate, like parts.
The block shewn in the perspective Figure 1 and in the section Figure 2 is
composed of a block or slab of fireclay, asbestos, metal, or other suitable material
or a combination of such materials, and is formed with two grooves or tunnels A,
formed in its underside. A shaft B is formed vertically from the roof of each
of the tunnels having its end open at the upper surface of the block.
The block may be of any convenient size and shape and may have one or more
grooves or tunnels as described above, of equal or unequal and regular or
irregular size and shape.
The grooves or tunnels may run fore and aft or from side to side or both, and
may traverse the whole or any part of the block, and may be continued up
the front and back and sides or either as may be desired.
The tunnels may run through the body of the block in lieu of being formed
in its underside. Any number of vertical shafts may be provided or they may
be omitted altogether.
The block may be in one piece or built up in sections.
The block may be placed upon the grating of any existing fireplace so as to
cover the whole or any portion of the grating or it may take the place of the
grating. Or a special grating may be provided with an open space in the desired
position wherein the block may be placed.
The block may be placed loose in the fireplace or it may be fixed in any
manner convenient.
When in use the air travelling along the grooves or tunnels becomes highly
beated by contact with the block and is drawn out at the ends and through the
vertical shafts into the fire, thus assisting in the perfect combustion of the fuel
and the consumption of smoke.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
(1) A block with grooves or tunnels running fore and aft in combination with
or without grooves or tunnels running transversely on the underside of or in
the body of the block.
(2) A block with grooves or tunnels on the underside of or in the body of the
block continued vertically on its face or faces.
(3) A block with a shaft or shafts rising vertically from grooves or tunnels.
(4) A block having a combination of any or all of the foregoing and as
described and as illustrated in Figures 1 and 2 of the accompanying drawings.
