Paris for an Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
BRICKS, TILES, PAVINGS KENNEL-STONES AND OTHER SIMILAR PRODUCTS

PROVISIONAL SPECIFICATION left by the said Armand Bouquié at the
Office of the Commissioners of Patents on the 5th August 1882.
ARMAND BOUQUIE of Boulevard Saint Denis N° 1 at Paris "IMPROVEMENTS

OTHER
My Invention relates to the manufacture of bricks, tiles, paving blocks, kennel
stones, and other like articles by means of sand and gas or mineral tar or pitch.
For this purpose I mix sand of any suitable description in the proportion of
94 per cent with 6 per cent of gas or mineral tar or pitch. I put these materials
into any ordinary mixer heated by steam or by an open fire so as to form them
into a pulp or plastic mass which I then compress while hot in moulds of the
required form.
-
By its fusion the tar or pitch becomes a binding medium and in cooling it
solidifies the mass and makes it impermeable. The silicious products thus formed
are therefore waterproof. I afterwards dip them in 'a bath of water saturated
with sulphate of iron mixed with red or yellow ochre to give them the appearance
of ordinary ceramic articles. This color not only makes the articles pleasing to
the eye, but also enables them to resist rain.

My Invention relates to the manufacture of bricks, tiles, paving blocks, kennel
stones, and other like articles by means of sand and gas or mineral tar or pitch.

page_text: For this purpose I mix sand of any suitable description in the proportion of
94 per cent with 6 per cent of gas or mineral tar or pitch. I put these materials
into any ordinary mixer heated by steam or by an open fire so as to form them
into a pulp or plastic mass which I then compress while hot in moulds of the
required form. By its fusion the tar or pitch becomes a binding medium and in
cooling it solidifies the mass and makes it impermeable. The silicious products
thus formed are therefore waterproof. I afterwards dip them in a bath of water
saturated with sulphate of iron mixed with red or yellow ochre to give them the
appearance of ordinary ceramic articles. This color not only makes the articles
pleasing to the eye, but also enables them to resist rain.
In the annexed drawings I show by way of example several articles which can
be made with advantage by means of my invention. Figure 1 represents in
exterior view a silicious brick B with grooves a a which render it lighter without
diminishing its strength. Figure 2 shows a silicious brick B¹ of the same form as
ordinary bricks made of burnt clay. Figure 3 represents a silicious square or
block C in top view, and Figure 4 a silicious block C' of octagonal form. Figure 5
is a top view of a silicious tile T. Figure 6 represents a paving block P for stables;
the channels or recesses b b are for the purpose of facilitating the flow of the urine
into the gutters; Figure 7 is a side view of the same block P. Figure 8 is a side
view of a silicious kennel stone which may be made of any desired length.
Figures 9 and 10 represent in face and side view a paving block with cavities and
projections; bb are the cavities to receive the projections a which have the effect
of preventing the partial subsidence of the blocks. In Figures 11, 12 and 13 I
bave shown in elevation, plan, and side view a description of paving block without
projections, but with cavities b b and channels c c for the purpose of allowing of
the introduction of cement which fills the cavities and the joints and thus prevents
partial subsidence.
Having now described the nature of my said Invention and in what manner the
same is to be performed I declare that I claim :-
First The manufacture of bricks, tiles, paving blocks and other similar articles
by mixing together sand and tar or pitch in proportions such as those stated,
converting these materials under the action of steam or of an open fire in a mixer
into a pulp or plastic mass and then moulding and compressing this mass while
hot into the forms required, substantially as herein before described.
Second-Submitting the bricks or other articles produced in the manner
referred to in the first claim to immersion in water saturated with sulphate of iron
mixed with red or yellow ochre as and for the purposes hereinbefore described.
In witness whereof I the said Armand Bouquié have hereunto set my hand
and seal this eighteenth day of January One thousand eight hundred and
eighty three.
Witness:
ALBERT CAHEN
Civil Engineer
of Boulevard Saint Denis 1
at Paris.
