PROVISIONAL SPECIFICATION.
An Improved Method of Using Small Coke or Breeze in the
Manufacture of Coke and Coke Bricks.
FREDERICK WILLIAMS 1 Zetland Buildings Middlesbrough Iron Merchant do
hereby declare the nature of this invention to be as follows:-
This invention has reference to an improved combination and method of treating
small coke from coke ovens and from various furnaces boilers &c. and forming
same into large masses similar to the ordinary coke of commerce or into blocks or
other required shape so as to adapt it for use in blast furnaces cupolas firing
boilers &c.
The materials I propose using being at present treated as waste and containing a
quantity of foreign matter, I proceed to cleanse it from such foreign matters by
washing or other suitable treatment. The cleaned small coke may be used as it is
after washing or preferably be ground into small particles. I then add to this
coke a percentage of coal (or other) tar-pitch, creosote or other hydro-carbon oils
resin vegetable or mineral oils or the wastes from the manufacture of paraffin or
petroleum. give the preference to pitch and tar where these materials can be
obtained cheaply.
After adding and thoroughly mixing the desired quantity of any of the materials
above specified with the small coke I put the mixture into an ordinary coke oven
or suitable furnace and then fire it until the volatile matter is driven off and the
mass is congealed together. Where bricks are required, the mixed coke tar &c. is
pressed into moulds and then placed into the coke oven or other furnace and heated
as before described.
The gasses from the ovens or furnaces may be utilized for the recovery of bye
products if deemed expedient.

An Improved Method of Using Small Coke or Breeze in the
Manufacture of Coke and Coke Bricks.
1, FREDERICK WILLIAMS 1 Zetland Buildings Middlesbrough Merchant 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 has reference to an improved combination and method of treating
the small coke from coke ovens and from various furnaces, boilers and the like and
forming same into large masses similar to the ordinary coke of commerce or into
blocks or other required shape so as to adapt it for use in blast furnaces, cupolas,
firing boilers and the like.
The material I propose using being at present treated as waste and containing
a quantity of foreign matter I proceed to cleanse it from such foreign matter by

page_text: washing or other suitable treatment. The cleansed small coke may be used as it
is after washing, or preferably be ground into small particles. I then add to this
coke a percentage of coal or other tar pitch, creosote, or other hydro carbon oils
resin, vegetable or mineral oils or the waste from paraffin or petroleum. The
proportion of the various cementing materials used varies considerably and depends
upon the materials employed and their condition. The quantities used may be
taken approximately at from 10 to 30 per cent. of the whole mass.
Where pitch is used 10 to 12 per cent. is sufficient and the same quantity of tar
is sufficient when it is comparatively free from water. When the tar contains
much water then a larger quantity will be required varying with the amount of
water present. As a general rule I prefer to add only sufficient of any of the
materials specified to make the mass adhere together when pressed. I give the
preference to pitch and tar where these materials can be obtained cheaply. After
adding and thoroughly mixing the desired quantity of any of the materials. above
specified to the small coke I put the mixture into an ordinary coke oven or suitable
furnace and there fire it until the volatile matter is driven off and the mass is
congealed together. Where bricks are required the mixed coke, tar or other
binding material is pressed into moulds and then placed into the coke oven or
other furnace and heated as before described. The gasses from the coke oven or
other furnaces may be utilized for the recovery of bye products such as sulphate
of ammonia, benzole, naphtha, tar pitch and the like if deemed expedient.
Having now described and ascertained the nature of my invention and in what
manner the same is to be performed I declare that what I claim is
1st. The preparation and treatment of small coke for manufacture into coke
bricks or masses substantially as described.
2nd. The burning or baking off of the tar or other cementing or binding
materials from the mixed mass of small coke and binding material in order to
produce dense homogenious and hard bricks or masses of coke as required.
3rd. The utilization of the volatile matter and gasses generated in the burning
or baking off of the cementing material for the production of bye products such as
'sulphate of ammonia benzole, naphtha tar-pitch and the like.
Dated this 11th day of December 1894.
