[Communicated from abroad by THE FIRM OF JACOB MEURIN, of Andernach
on the Rhine, Germany, Manufacturers and Mine Proprietors.]
An Improved Manufacture of Bricks, Slabs, Pipes, Pipe-stones,
and other similar articles.
I, CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery
Lane, in the County of London, Consulting Engineer and Patent Agent, do
hereby declare the nature of this invention to be as follows
:-
This invention consists in the manufacture of bricks slabs pipes, pipe-stones, and
other similar articles used for building purposes, of a volcanic material known as
pumice-sand or pumice-gravel, found more particularly at the Laacher Lake near
Coblenz Germany, which material is mixed with either slaked lime or gypsum or
cement.
These substances are mixed together with water in the proportions of about
1 part of lime &c. to from 5 to 8 parts of pumice-sand or gravel and the mixture is
introduced into suitable moulds for forming solid or perforated bricks, slabs, pipes,
pipe stones and other objects. After setting, the bricks are removed from the
moulds and are stacked in the sun to dry, when they will become perfectly hard
and strong, being suitable for all purposes for which bricks and other objects made
of burnt clay are used. Bricks manufactured according to the above described
invention have the advantage of being more than twice as light as ordinary bricks
while they possess nearly the same strength, and by their use in building a great
economy is consequently effected both in transport, and in the strength of
foundations, also in the building of light arched roofs or ceilings, tall chimnies,
hollow brickwork floors &c. In the latter application such bricks also afford the
great advantage of being very sound proof, and thus saving the cost of more
expensive appliances for this purpose.
Being very porous, such bricks &c. are also very bad conductors of heat, and
they also form a very effective fire-proof material. The bricks possess a very
rough surface and consequently bind together most effectually when laid in mortar
or cement, and afford a very efficient keying surface for plastering.

COMPLETE SPECIFICATION.
An Improved Manufacture of Bricks, Slabs, Pipes, Pipe-stones,
and other similar articles.
I, CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery
Lane, in the County of London, Consulting Engineer and Patent Agent, 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 consists in the manufacture of bricks slabs pipes, pipe stones, and
other articles used for building purposes, such as string courses, mouldings, door
jambs and other profile stones, of a volcanic material known as pumice-sand or
pumice-gravel found more particularly at the Laacher Lake near Coblenz
Germany; but which also occurs in other localities such as the valley near
Andernach-Neuwied, Iceland &c., which material is mixed with either slaked
lime or gypsum, or cement, or other suitable binding material.

These substances are mixed together with water in the proportions of about
1 part of lime &c. to from 5 to 12 parts of pumice-sand or gravel, and the mixture
is introduced into suitable moulds for forming solid or perforated bricks, slabs,
pipes, pipe stones and other objects; or the requisite configuration may be imparted
to the blocks by other known means, such as by pressing through dies by suitable
machinery. After setting, the bricks are removed from the moulds and are stacked
in the sun in closed or heated spaces, to dry, when they will become perfectly hard
and strong, being suitable for all purposes for which bricks and other objects made
of burnt clay are used. Bricks manufactured according to the above described
invention have the advantage of being more than twice as light as ordinary bricks,
while they possess nearly the same strength, and by their use in building a great
economy is consequently effected both in transport, and in the strength of
foundations, also in the building of light arched roofs or ceilings, tall chimneys,
hollow brickwork floors &c. In the latter application such bricks also afford the
great advantage of being very sound proof, and thus saving the cost of more
expensive appliances for this purpose.
Being very porous, such bricks &c. are also very bad conductors of heat, and
they also form a very effective fire-proof material. The bricks possess a very
rough surface and consequently bind together most effectually when laid in mortar
or cement, and afford a very efficient keying surface for plastering.
Having now particularly described and ascertained the nature of this invention
to which I have given the name of "Meurin's Pumice Blocks" and in what manner
the same is to be performed, I declare that what I claim is :-
An improved manufacture of bricks slabs pipes, pipe-stones, blocks, mouldings,
and the like, consisting of a mixture of pumice-sand or pumice-gravel with a
suitable binding material, such as lime, gypsum or cement, the said mixture being
filled into moulds or having the required configuration otherwise imparted to it,
and left to harden before use, substantially as herein described.
