I, WILLIAM TEMPLE of Osborne Road in the City and County of Newcastle upon
Tyne, Builder do hereby declare the nature of this invention to be as follows:-
The object of this invention is to obtain a more effectual discharge of the clay from
horizontal brick making machines.
I accomplish the above object in the following manner :-I form a new mouthpiece
to a horizontal brick making machine, whereby instead of at present having only one
orifice or die through which the clay passes, I obtain two orifices or dies.
The stream of clay instead of being driven out in the same line as the shaft is divided
and passes out by this mouth piece in two streams through the orifices or dies, arranged
at an angle of from 30 to 60 degrees from the line of the shaft, and thus the output of
clay for cutting into bricks is increased without any further power being required.
Dated this First day of July 1886.

COMPLETE SPECIFICATION.
An Improved Mouthpiece for Horizontal Brickmaking Machines.
I WILLIAM TEMPLE, of Osborne Road, in the city and county of Newcastle upon
Tyne, Builder, 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 relates to providing horizontal brickmaking machines with an
improved mouthpiece so arranged as to allow of obtaining a more effectual discharge
of the clay from the pug mill.
Hitherto this class of machine has generally been constructed with only one orifice
through which the clay passed out in a line with the shaft.

page_text: According to my invention I form the mouthpiece double, that is to say, with two
orifices or dies arranged at an angle of from thirty to sixty degrees from the line of
the shaft so that the clay in passing from the pug mill is divided and passes out through
the two orifices or dies.
In order to enable my invention to be fully understood I will proceed to describe
how my invention may be carried into effect by reference to the accompanying drawing
in which figure 1 represents a horizontal section shewing my improved or double
mouthpiece at the end of a pug mill. Figure 2 is a vertical section through the mouth-
piece on line a, b, of figure 1 and figure 3 is an elevation looking at the mouthpiece
from the front. Similar letters in all the figures represent similar parts.
a, a, is the outer casing of an ordinary pug mill; b, is the end of the shaft; c, c, c,
my improved or double mouthpiece; d, d, the orifices through which the clay passes
in two streams into the dies or die boxes fastened to the mouthpiece in the usual way.
The clay is forced out of the pug mill by the shaft b, in the usual manner but when
the clay arrives at my double mouthpiece it is divided into two streams and passes
out by the orifices d, d, whereas in the ordinary construction of mouthpiece the clay
passes out in a straight line with the shaft and the shaft rotating causes the clay to
form into a curl and receive a core in the centre which is the cause of unsoundness
in the bricks when burnt and also causes a considerable loss in drying and burning.
By the use of my double mouthpiece this core is not formed and a better brick is
therefore made than has hitherto been made in this class of machine. This improve-
ment is effected by the clay being divided into two streams by my double mouthpiece
whereby the core is cut through and the curl is broken, by which means a much
sounder brick is obtained. A considerable saving of power is also effected by my
invention as compared with the ordinary single mouthpiece; the output of clay is
also considerably increased and there being a greater opening the clay passes through
the orifices more freely and offers less resistance to the pugging.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
1. Providing horizontal brickmaking machines with a double mouthpiece the
orifices or dies of which are placed at an angle to the shaft of the pug mill substantially
as and for the purposes herein before described.
2. The improved mouthpiece for horizontal brick making machines hereinbefore
described and illustrated in the several figures of the accompanying drawing.
