PROVISIONAL SPECIFICATION.
Improvements in Fuel Blocks.
We BARNABAS FREDERICK KELLY of Wellington House Bilston in the County. of
Staffori, JOSEPH HENRY SPENCER of Trinity Road Birchfields Birmingham in the
County of Warwick and HERBERT SPENCER of Euston House 7 Highfield Road
Edgbaston in the County of Warwick all manufacturers, do hereby declare the nature
of our said invention to be as follows:-
Our invention has for its object Improvements in fuel blocks which are so made
as to be capable of burning upon ordinary fires. Much difficulty has been
experienced with the fuel blocks now in use because combustion cannot be properly
effected without either a very strong draft or by breaking the blocks up into small
pieces.
We make our blocks or fuel bricks with a series of holes either round hexagonal,
square, or other suitable shape passing through them, either from the flat way or
edgewise or lengthwise, but by preference through the thickness so that when laid
upon a fire the draft is not stopped as it is at liberty to pass up through the said
holes and the blocks are thus more easily consumed. There is also the further
advantage that the blocks may be more easily broken into small pieces, when so
required. It will be obvious that our invention not only applies to bricks, or blocks
made from coal-slack but also when made from peat, or other suitable composition
of combustible material.

COMPLETE SPECIFICATION.
Improvements in Fuel Blocks.
We BARNABAS FREDERICK KELLY of Wellington House Bilston in the County of
Stafford, JOSEPH HENRY SPENCER of Trinity Road Birchfields Birmingham in the
County of Warwick and HERBERT SPENCER of Euston House 7 Highfield Road
Edgbaston do hereby declare the nature of our said invention to be particularly
described and ascertained in and by the following statement :-
Our invention has for its object improvements in fuel blocks made from moulded
coal dust or slack which is so made as to be capable of burning upon ordinary fires.
Much difficulty has been experienced with the fuel blocks now in use because com-
bustion cannot be properly effected without either a very strong draught or by
breaking the blocks into small pieces.
We make our blocks or fuel bricks with a series of holes either round hexagonal
square or other suitable shape passing through them either from the flat way or
edgewise or lengthwise but by preference through the thickness so that when laid
upon a fire the draught is not stopped as it is at liberty to pass up the said holes
and the blocks are thus more easily consumed.
There is also the further advantage that the blocks may be more easily broken
into small pieces when so required. It will be obvious that our invention not only
applies to bricks or blocks made from coal slack but also when made from peat or
other suitable composition of combustable material,
In order that our invention may be clearly understood and easily carried into
practice we have appended hereunto a double sized sheet of drawings upon which we
have shown several modes of carrying the invention into effect and by the help of.
which many other modifications may be effected,

page_text: Figure 1 shows one of our blocks A with the holes a' piercing through thickness
thereof so that if this block or a part of it when broken even put upon a fire the
draught or smoke would be free to ascend through any of the holes al so as to
encourage combustion. These holes also enable the blocks to be more easily broken
when required in smaller pieces as it is sometimes the case.
Figure 2 shows one of our blocks B with the holes b' piercing through the width
of the block which make this block suitable for placing upon a fire edgewise down-
wards so that several such blocks might be placed side by side upon a fire with
perhaps a little small at the back when there would be perfect freedom for the
currents through the holes b¹.
Figure 3 illustrates one of our blocks C with the holes of running through end-
wise the full length of the block so that these blocks could be placed upon a fire
endwise and any number used.
Figure 4 shows a block E broken off in which the holes e¹ are of hexagon shape
thus giving parallel partitions between the holes. Of course we do confine ourselves
to any particular shape for either the holes or the blocks themselves. As these
details may be greatly varied both as to size and shape of blocks and the holes
may run through several directions of the one block for instance in the case of
Figure 5 the cubical block K has six holes one from each side all meeting at the
centre so that any side may be placed upon the fire.
The sides or faces of the blocks may be corrugated or grooved to assist combustion
when several come side to side as per Figure 6.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
The improvements in fuel blocks consisting of the perforations or grooves to
assist combustion substantially as and for the purpose herein set forth and as shewn
upon the drawings
