PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Patent Fuel.
I, JOHN BAYNTON TAYLOR Paradise Cottage Bath, do hereby declare the nature
of this invention to be as follows:-
This invention has for its objects-1st. To render patent fuel of every description
sinokeless (or as nearly so as is possible). 2nd. To increase its heating or combustion
surface. 3rd. To increase its heating power (its whole mass being rendered heat-
giving at once, instead of as now only a part of it). 4th. To prevent waste in
smoke, ash and cinder. 5th. To render its use more economical. 6th. Where the
results obtained from this fuel are compared with equal results from coal and other
fuel the cost for transport and storeage space of a sufficient quantity of this fuel
to produce such results will be found to be considerably less than that of the other
kinds. 7th. Owing to the enormous heating power and perfect combustion of this
fuel smaller fire grates can be used-steain can be produced at much higher
pressure than is now possible-smoke consuming apparatus can be dispensed with.
The fuel will produce no waste-and will not clinker on the fire bars.
By patent fuel we mean what is generally understood by that name-for example
any kind of small coals, or any mixture of various kinds thereof, either alone or
combined with other substances-and formed, shaped, moulded or compressed into
blocks or briquettes of various shapes and sizes which are to be used instead of
lump coal.
To achieve these objects we employ either separately or together any or all of
the following methods vizt. 1st. To have one or more perforations running right
through the block of patent fuel. 2nd. By having on the outside of the block
indentations (such as flutings) running from one side to the other side-or from
one end to the other end of the block (in some cases they may be of a less length).
3rd. By having the edges and corners of the block bevelled off so as to increase
its surface and make it many sided. 4th. By making the blocks of a spherical-
elliptical-oviform or circular section. N.B.-The foregoing perforations and
indentations may be of any cross section that is found to be most suitable for any
particular purpose.
These blocks may be moulded-pressed-shaped or formed either by hand or
machinery, in any way that patent fuel is now made, or in which it may be made
only having suitable provision made in the appliances used in its manufacture-so
that the fuel can be made in the way above described-all of which will be more
fully explained in the Complete Specification.
Dated this Seventh day of July 1894.
COMPLETE SPECIFICATION.
Improvements in the Manufacture of Patent Fuel.
I, JOHN BAYNTON TAYLOR, Paradise Cottage, Bath, Lay Reader for St. Mark's
0 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 objects of the following invention are to render patent fuel-1st. Smokeless

page_text: (or as nearly so as can be). 2nd. To increase its combustion surface and heating
power. 3rd. To render it more economical. 4th. To make it less bulky than an
amount of ordinary fuel yielding corresponding practical results, thus saving in
storeage space and cost of transit. 5th. To prevent waste in smoke ash, gases and
cinders. 6th. To prevent smoke fogs and consequently damage to life and property.
7th. To utilise small coal now wasted. 8th. To utilise atmospheric gases to
save fuel.
By patent fuel is meant small coal, either alone or in combination with other
materials formed, shaped, moulded, or compressed, into blocks or briquettes to be
used as fuel. The harder they are pressed the better.
To achieve the foregoing objects we employ either separately or together any or
all of the following methods in the manufacture of the patent fuel, vizt. 1st. To have
one or more perforations K. of any cross section and as large as possible, running
right through the fuel block. 2nd. To have on the outside of the fuel block
indentations L (such as flutings or grooves) running either partly or entirely from one
aide, or one end to the other. 3rd. The edges or the corners of the fuel block may
be bevelled off M or rounded off N so as to increase the number of its sides.
4th. The fuel blocks may be made oval, oviform globular, elliptical or of any shape
that will allow plenty of spaces between the blocks. The aforesaid blocks may be
either moulded or pressed-or shaped or formed either by hand or by machinery.
The result of making the blocks in this way is to provide the utmost air space,
around through and within them-and to have the solid fuel as thin in its cross
section as is possible. In this way the objects of this invention can be fully
realised.
Smoke the cause of fog, is caused because ordinary fuel is not properly ventilated
throughout its mass, consequently there is not sufficient oxygen supplied to consume
the smoke, and gases which are given off to escape up the chimney instead of being
consumed in the furnace, as they would be were this invention applied to the fuel.
The consumption of such gases and smoke particles, also of the gases in the air
current which permeates the fuel-in the furnace, would save an immense quantity
of fuel, as well as prevent smoke, and increase the heating power of the furnaces.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is,
To make patent fuel blocks with
1st. Perforatious through them.
2nd. Indentations on the surfaces thereof.
3rd. Bevelled or rounded edges or corners, and
4th. Of any shape as I have above described-and as I have hereinbefore more
fully set out.
Dated this Eighth day of April 1895.
