Year: 1882

page_text: LETTERS PATENT to Thomas Adamson Riggs of Aldeburgh in the County
of Suffolk, for an invention of A NEW OR IMPROVED COMBINATION OF
SUBSTANCES FOR THE MANUFACTURE OF BRICKS, BLOCKS, TILES, STEPS,
PAVEMENTS, AND OTHER ANALOGOUS ARTICLES
PROVISIONAL SPECIFICATION left by the said Thomas Adamson Riggs at
the Office of the Commissioners of Patents on the 22nd April 1882.
THOMAS ADAMSON RIGGS of Aldeburgh in the County of Suffolk. A NEW OR
IMPROVED COMBINATION OF SUBSTANCES FOR THE MANUFACTURE OF BRICKS,
BLOCKS, TILES, STEPS, PAVEMENTS AND OTHER ANALOGOUS ARTICLES
The object of my invention is to utilize the substance known as "Coralline
Craig" in the manufacture of bricks, blocks, tiles, steps, pavements and other
analogous articles. With this object I take the "Coralline Craig and Portland or
other cement or lime, and reduce them to powder, having a suitably sized grain, in
any convenient machine. These substances are then well mixed together, in the
proportion of 4 parts of "Coralline Craig" to 1 part of cement or lime, or there-
abouts. If necessary for the requirements of the various articles I make of these
substances, I can add to this mixture, either in addition to, or in lieu of part of, this
proportion of "Coralline Craig" soine small proportion of sand or other similar
material. Sufficient water is then added to give the necessary consistence and
cohesion to this mixture, and the whole is well stirred together. If I desire to
colour these articles, I can add any suitable colouring matter to this mass, which is
then formed into the bricks or blocks or other articles as I may require, in any
convenient moulds or otherwise. The bricks or other articles are then subjected to
pressure until they are perfectly homogeneous; and when dried, they are ready for
use. They can also be enamelled or further treated for their ornamentation, after
drying, as I may require.

THOMAS ADAMSON RIGGS of Aldeburgh in the County of Suffolk A NEW OR

This
The object of my invention is to utilize the substanco known us "Coralline
Craig" in the manufacture of bricks blocks tiles steps pavements and other
analogous articles. With this object I take the "Coralline Craig" and reduce it
to powder in any convenient machine. I can also reduce the "Coralline Craig " to
the condition require by washing the same in any convenient manner.
-process I find very suitable in some instances as it not only reduces the "Coralline
Graig" to the desired condition but also renders it very-fit-for-the-processes
hereinafter described. I also find it occasionally desirable to burn the "Coralline
Craig" or subject it to the action of heat in a suitable kiln or otherwise. This
process reduces it to a material somewhat similar to lime and by increasing its
cohesion with the other substances hereinafter mentioned renders the bricks blocks
or other-articles-made after this manner stronger and tougher and less liable to
give way under a heavy strain or pressure. I also take Portland or other cement-
or lime and reduce this also if necessary to powder of similar consistence. These
substances "Coralline Craig" and Portland or other cement or lime having been
treated as herein before described are well mixed-together in the following
proportions or thereabouts. For ordinary bricks I use four parts of "Coralline
Craig" to one part of cement or lime. For facing bricks or bricks for special
purposes I increase the proportion of cement or lime and use four parts of
"Coralline Craig" to one and a half or two parts of cement or lime. For steps
or pavements or other analogous articles I still further increase the proportion of
cement or lime and use four parts of "Coralline Craig" to three or more parts of
cement or lime. But though I consider these proportions as aforesaid to be the
best for my various purposes hereinbefore described I would have it clearly
understood that I do not limit myself to these exact proportions hereinbefore
mentioned but that the same may be slightly varied as I deem expedient. If
necessary for the requirements of the various articles I make of theso substances I
can add to this mixture either in addition to or in lieu of part of this proportion
of "Coralline Craig" as aforesaid some small proportion of sand or other similar
material. This has the effect of increasing the cohesion of the substances and
therefore the strength of these articles and is useful in some instances. Sufficient
water is then added to give the necessary consistence to this mixture and the whole
is well stirred together. If I desire to colour the articles I make from this minss I
can add any suitable colouring matter thereto and the bricks or, blocks or other
articles are then formed from the mass in any suitable moulds or otherwise. The
bricks or blocks or other articles so formed may then be subjected to pressure until
they are perfectly homogeneous. This process is sometimes necessary when great
strength is required in the said articles but it may be performed whenever I deem
desirable. These articles are then allowed to dry and when so dried they are ready
for use in their various manners. These articles can also be enamelled or further
treated for their ornamentation as may be required.
Having thus particularly described and clearly explained any invention and in
what manner the same is to be performed and used I claim as my invention which
is protected by the herein before in part recited Letters Patent
