Year: 1876

page_text: LETTERS PATENT to Sydney Turner, of Beverley, in the County of York, Civil
Engineer, for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR MAKING BRICKS OR OTHER ARTICLES OF A PLASTIC NATURE."
Sealed the 21st November 1876, and dated the 27th May 1876.
PROVISIONAL SPECIFICATION left by the said Sydney Turner at the Office
of the Commissioners of Patents on the 27th May 1876.

PROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING BRICKS OR OTHER
ARTICLES OF A PLASTIC NATURE."
This Invention relates to certain novel improvements in the application or con-
struction and working of machinery or apparatus to be used in or for the making of
bricks or other articles of a plastic nature.
The working parts of the improved machine are contained within a cylinder
forming the bottom or a continuation of a pug mill, the shaft of which depends
into the cylinder, and works in a brass step seated centrally in its bottom. At
this part the shaft is squared, and carries an upper and an under circular disc, each
being fixed upon the shaft excentrically. These discs are kept apart by hollow
columns, and are united by bolts passing therethrough; they are also united by
pins on which work cylindrical friction rollers, around which and also between the
two discs is placed a cylindrical excentric strap, which is thus driven or carried
around within the said cylinder without itself rotating together with the excentric
discs by the revolution of the pug mill shaft. The cylinder is provided with a
lateral mouth or opening, through which by this movement of the excentric strap
the clay or other material is directly pressed or forced into a die of such form as
may be required. The clay or other material is caused to issue through this mouth or
opening by a vertical plate, which works in connection with the excentric strap
between guide rollers carried in a lateral orifice in the cylinder. Immediately
above the upper excentric disc an inner projecting flange of the cylinder carries
horizontally a plate of such a shape as to cause the clay or other material to
descend from the pug mill into the cylinder on the mouth or exit side of the said
vertical plate, whence by the combined action and movement of the said excentric
strap and vertical plate within the cylinder it is directly pressed or forced through
the said mouth.

page_text: In machines used for this purpose, as hitherto constructed, the clay or other
material has been forced out by a rubbing pressure which the above-described
improvements entirely avoid, and which necessarily considerably increased the
power required.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Sydney Turner in the Great Seal Patent Office on the 27th November
1876.

"IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING BRICKS OR OTHER ARTICLES
OF A PLASTIC NATURE."
This Invention relates to the application of certain novel improvements in the
construction and working of machinery or apparatus to be used in or for the
making of bricks or other similar articles of a plastic nature.
The improved apparatus is illustrated on the accompanying Sheet of Drawings,
in Figures 1 to 3, which are drawn to a scale of two inches to the foot, and of
which Figures 1 and 2 represent plan views, Figure 2 being in section through
X-X, Figure 3, and Figure 3 is a sectional elevation through Z-Z, Figure 1.
The working parts of the improved apparatus are contained within a cylinder 1,
forming the bottom or lower continuation of a pug mill, the shaft 2 of which
depends into the cylinder 1, and works in a brass step 3 seated centrally in its
bottom. Within the cylinder 1 the shaft 2 is squared, and on this part it carries
upper and under circular discs 4, 5, which are fixed upon it excentrically, and kept
apart by hollow columns 6 rising from the disc 5, and hold in position by bolts 7
passing therethrough. The discs 4, 5, are also united by pins fixed therein, and
on which work cylindrical friction rollers or rings 9. Encircling the series of
these rings, and placed between the discs 4, 5, is a cylindrical excentric strap 10,
which is thus driven or carried around within the cylinder 1 without itself
rotating, together with the discs 4, 5, by the revolution of the pug mill shaft 2.
The cylinder 1 is provided with a lateral mouth or opening 11, through which by
this movement of the excentric strap 10 the clay or other plastic material is directly
pressed or forced into a die of such form as may be required. The clay is caused
to issue through the mouth or opening 11 by a vertical plate 12, which is con-
nected to and works in connection with the excentric strap 10 passing between
guide rollers 13 arranged vertically in a lateral orifice 14 in the cylinder 1.
Immediately above the disc 4 an inner projecting flange 15 of the cylinder 1 carries
horizontally a plate 16 of such a shape (see Figure 1) as to cause the clay or plastic
material to descend from the pug mill into the cylinder 1 on the mouth or exit side
of the plate 12, whence, by the combined action and movement of the excentric
strap 10 and plate 12 within the cylinder 1, it is directly pressed or forced through
the mouth 11,
In apparatus used for the purposes of this Invention, as hitherto constructed, the
clay or other material has been forced out by a rubbing pressure, which necessarily
considerably increased the power required; but by the application and use of the
above-described improvements this is avoided.
Having now described the nature and object of my said Invention, together with
the manner in which the same is to be or may be performed or carried into practical
effect, I would remark in conclusion that I claim as my Invention, the novel and
peculiar application of the above-described improvements to or in the construction
of apparatus used in the making of bricks or other similar articles of a plastic
nature, and the combined action of the various component parts in forcing clay or
other plastic material through an orifice to form a brick or other similar article,

Drawings.
In witness whereof, I, the said Sydney Turner, have hereunto set my hand
and seal, this Twenty-second day of November, in the year of our Lord One
thousand eight hundred and seventy-six.

presence of
TOM TURNER,
