IMPROVEMENTS IN MACHINERY FOR MAKING BRICKS, TILES, AND OTHER SIMILAR ARTICLES
Year: 1877

page_text: LETTERS PATENT to Abel Mayer, of Hanley, in the County of Stafford, Engineer,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR MAKING BRICKS,
TILES, AND OTHER SIMILAR ARTICLES."
Sealed the 20th May 1877, and dated the 3rd February 1877.
PROVISIONAL SPECIFICATION left by the said Abel Mayer at the Office of
the Commissioners of Patents on the 3rd February 1877.
ABEL MAYER, of Hanley, in the County of Stafford, Engineer. "IMPROVEMENTS
IN.MACHINERY FOR MAKING BRICKS, TILES, AND OTHER SIMILAR ARTICLES."
My improved machine consists of a table, at the end of which is a horizontal
pug mill, and in which is a slide containing a compound mould of the shape of two
or more bricks or other articles to be produced. The pistons in the mould are
raised by eccentrics or cams and levers or other equivalents, and they drop by their
own gravity. The pug mill delivers the clay on to a slide which, when drawn aside,
allows the feeding plunger to force the clay into the mould which is moved to and
fro on the table so as to bring the mould alternately under the feeding plunger and
under the press.
The pressure for consolidating the bricks or other articles is obtained by one
eccentric actuating a lever, and by side levers connected by links to the press
slide.
When the machine is at work the compound mould after it has received its
charge of clay or other material from the pug mill is traversed towards the press;
and when the pressure has been given and the slide is going back again, the pistons
of the mould are carried over an inclined lever raised by an eccentric which lifts
the pressed bricks or other articles out of the mould and raises them level with the
table ready to be removed; by this arrangement the moulds are filled and the
bricks or other articles are pressed continuously. The moulds are lubricated after
the bricks or other articles have been removed by a saturated pad or brush, in the
ordinary manner.

IN MACHINERY FOR MAKING BRICKS, TILES, AND OTHER SIMILAR ARTICLES."

My improved machine consists of a table, at the end of which is a horizontal
pug mill, and in which is a slide containing a compound mould of the shape of two
or more bricks or other articles to be produced. The pistons or plungers in the
mould are raised by eccentrics or cams and levers or other equivalents, and they
drop by their own gravity. The pug mill delivers the clay on to a slide which,
when drawn aside, allows the 'feeding plunger to force the clay into the mould
which is moved to and fro in the table so as to bring the mould alternately under
the feeding plunger and under the press.
The pressure for consolidating the bricks or other articles is obtained by
one eccentric actuating a lever, and by side levers connected by links to the press
slide.
And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings.
Fig. 1 is an elevation; Fig. 2, an end view; and Fig. 3, a plan of my improved
machinery for making bricks, tiles, and other similar articles.
The machine consists of two side frames a, a, and a table b on which is fixed an
'ordinary horizontal pug mill c. In the table is a long slot for the slide d to move
to and fro in. This slide contains a compound moulde of the shape of two or more
bricks or other articles to be produced; f, f, are the pistons or plungers of the
mould e.
The sides or ends of the mould box are provided with slots and the
plunger has inovable studs fitting in the said slots. These studs can be fixed in
different positions, according to the thickness of the brick or tile that is being made.
When the piston is down the studs rest on the bottom of the slots in the mould.
The plungers fare raised by the cam g¹ fixed on the main shaft g. The cam g' acts
on the inclined lever h¹ which is hinged to the stud h passing through the standard h²
bolted to the foundation plate of the machine. The press plates fi are moved up
and down by the eccentric g³ on the shaft g. This eccentric acts on the long arm
of the double lever k fixed on the shaft g, to which is also fixed the lever k; the
short arm of the lever and the lever ¹ are connected to the cross head of the
press plates by the side links . The feeding plunger i which presses the clay
from the pug mill c into the compound mould e is raised and lowered by the cam g¹
which revolves in a frame, the upper end of which is connected by a link i² to the
lever i, to which the feeding plunger is suspended; this plunger and the frame are
counterbalanced by the weight 3, and the slide d is moved to and fro by the
quadrant lever which is fixed on the shaft , the said lever having a segmental
slot for the stud of the link m which is jointed to a bracket fixed at the under side
of the table d. The object of the slot is to allow the slido to dwell at each end of
its traverse while the mould is being filled and the pressure is given. The shaft l
is made to oscillate by means of the crank g on the main shaft g, which crank is
connected to the lever 12 on the shaft by the link o. The shaft g is turned slowly
round from the driving shaft p by the pinion p' gearing into the wheel q² on
the shaft g, to which is also fixed the pinion q gearing into the wheel gⓇ on the
shaft g.
When the machine is at work the compound mould e, after it has received its
charge of clay or other material from the pug mill c, is traversed towards the press,
and when the pressure has been given and the slide d is going back again the
pistons or plungers of the mould are carried over the inclined lever h¹ after it has
been raised by the cam g¹ which lifts the pressed bricks or other articles out of the
mould and raises them level with the table b ready to be removed; by this arrange-
ment the moulds are filled and the bricks or other articles are pressed in continuous

page_text: succession. The moulds are lubricated after the bricks or other articles have been
removed by a saturated pad or brush in the ordinary manner.
The whole machine may be mounted on wheels and moved from one part of the
brick croft to another.
Having thus stated the nature of my Invention and described the manner of
performing the same, I wish it to be unnerstood that I do not intend to limit my-
self to the details given, and that what I claim as my improvements in machinery
for making bricks, tiles, and other similar articles is the improved combination of a
pug mill, a feeding plunger, a press, and a compound or other mould fixed to a slide
moving to and fro in the table, and the apparatus for discharging the bricks or
other articles from the mould, as shewn and described.
In witness whereof, I, the said Abel Mayer, have hereto set my hand and
seal, this Twenty-fourth day of July, One thousand eight hundred and
seventy-seven.
ABEL MAYER. (L.S.)
