"
PROVISIONAL SPECIFICATION left by the said Thomas Whittaker at the
Office of the Commissioners of Patents on the 27th October 1883.
THOMAS WHITTAKER of Accrington in the County of Lancaster, Engineer,
IMPROVEMENTS IN TREATING CERTAIN RESIDUAL MATTERS FROM TOWN REFUSE
IN THE MANUFACTURE OF BRICKS BLOCKS AND TILES,
Town refuse, that is street sweepings midden and dust bin refuso, refuse from
houses hotels offices and buildings generally and all like residuals when assorted
into classes, yields a large quantity of cinders mixed with other matters, which,
when burned on an ordinary fire grate as for raising steam and other purposes,
leaves a very large quantity of clinker. It is the object of the present invention
to utilize such residual clinkers by mixing them with clay or other suitable
material such as cement, sludge, mud, or other adhesive bye products, in the
manufacture of bricks, blocks and tiles: and the scope of the present invention is
making valuable that which at present entails expense not only in removal from
the works but in room for deposit.
In order to effect proper admixture of the clinker and clay or other suitable
material as above mentioned the following special treatment is necessary before
moulding. The clinker is ground or pulverized under edge runners or otherwise;
the ground mass is sifted or treated for the removal of metallic or other unsuitable
substances; the pulverized and sifted clinker is dusted, sprinkled or coated with
powdered or other suitable material as above mentioned or with thin slip or like
semi-liquid matter and finally the prepared clinker is intimately mixed with the

page_text: required quantity of clay or other suitable material in a pug mill or in other
convenient machinery.
The mixed clinker and clay or other suitable material is now ready for moulding
into bricks blocks and tiles and this is effected in the wet, semi dry, or dry way
according to the quantity of moisture contained in or added to the mixed materials.
The clinker should be in proportion of about 80 to 90 per cent, and the clay or
other material 20 to 10 per cent. The coarser the grinding the greater the
quantity of material mixed with the clinker.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Whittaker in the Patent Office on the 26th April
1884.

"IMPROVEMENTS IN TREATING CERTAIN RESIDUAL MATTERS FROM TOWN REFUSE IN
THE MANUFACTURE OF BRICKS BLOCKS AND TILES."
Town refuse, that is street sweepings midden and dust bin refuse, refuse from
houses hotels offices and buildings generally and all like residuals when assorted
into classes, yields a large quantity of cinders mixed with other matters which,
when burnt on an ordinary fire grate as for raising steam and other purposes,
leave a very large quantity of clinker.
It is the object of the present invention to utilize such residual clinkers by
mixing them with clay or other suitable material such as cement sludge mud or
other adhesive bye products in the manufacture of bricks, blocks and tiles: and
the scope of the present invention is making valuable that which at present, entails
expense not only in removal from the works but in room for deposit.
In order to effect proper admixture of the clinker and clay or other suitable
material as above mentioned the following special treatment is necessary before
moulding. The clinker is ground or pulverized under edge runners or otherwise :
the ground mass is sifted or treated for the removal of metallic or other unsuitable
substances; the pulverized and sifted clinker is dusted sprinkled or coated with
powdered clay or other suitable material as above mentioned or with thin slip or
like semi liquid matter and finally the prepared clinker is intimately mixed with
the required quantity of clay or other suitable material in a pug mill or in other
convenient machinery.
The mixed clinker and clay and other suitable material is now ready for
moulding into bricks, blocks, and tiles and this is effected in the wet semi dry or
dry way according to the quantity of moisture contained in or added to the mixed
materials.
The clinker should be in the proportion of about 80 to 90 per cent and the clay
or other material 20 to 10 per cent.
Having now described and particularized my said invention in such manner
that others will be enabled to carry my improvements into effect I claim ;—
First. Treating residual matters for the manufacture of bricks blocks and tiles
in the manner herein setforth

page_text: Second. Grinding sifting and coating clinker obtained from residuals for the
manufacture of bricks blocks and tiles substantially as herein setforth.
Third. The manufacture of bricks blocks and tiles from clinker obtained and
treated substantially as herein setforth.
Fourth Mixing clinker treated as herein setforth with clay or suitable material
in the manufacture of bricks blocks and tiles.
In Witness Whereof I the said Thomas Whittaker have hereunto set my hand
and seal this twenty fifth day of April in the year of Our Lord, one thousand,
eight hundred and eighty four.
