Improvements in Machinery for Making and Pressing Bricks and
the like.
We, WILLIAM WILKINSON and HERBERT ALEXANDER, both of Neville
Works, Elland Road, Leeds, in the County of York, Engineers, do hereby declare
the nature of this invention to be as follows:-
The object of our invention is to improve the construction of brick making and
pressing machines in such a manner that the said machines shall occupy less room,
while at the same time they shall act more efficiently than those at present in use.
The first part of our invention relates to the construction and combination of
parts for transmitting motion from the driving shaft of the machine to the shaft
of the stamping or pressing arrangement. In machines of this type as hitherto
generally constructed, the motion has been communicated by means of a spur
wheel mounted on the driving shaft and gearing with a spur wheel mounted on an
auxiliary shaft, which latter by means of bevel gearing has hitherto transmitted
the motion to the shaft of the pressing arrangement. This arrangement is
disadvantageous owing to the necessity of having a bearing on the extremity of
the auxiliary shaft, which causes the driving pulleys of such shaft to be placed
further away from the machine; besides, the number of parts contained in such
arrangement causes a large amount of friction, and also much expense in making.
According to our invention we mount a bevel wheel on the end of the main
shaft, and we prolong the shaft of the pressing arrangement, and mount on the
extremity thereof a bevel wheel in such a manner that the said bevel wheels gear
one with the other. In this manner we obviate the necessity of employing an
auxiliary shaft, and can thus bring the main driving pulleys closer to the machine,
consequently reducing the width of such machine considerably.
The second part of our invention relates to the table which receives the bricks
from the cylindrical mould. This table has hitherto been made in one piece, and
owing to the shocks caused by the action of the plunger, such plate is constantly
liable to be broken. To overcome this liability of breaking, we make our table
in three parts; the first part of such table, upon which the brick is received, we
make comparatively thin, such part being supported on the framework of the
machine. The second part of the table is made very deep, as it contains the mould
in which the brick is pressed, and this second part is slidden into position between
the plungers, on guides situated in the main frame. The third section or part is
comparatively thin, like the first section, and is slidden in slides on the framework,
its end resting upon a ledge on the centre section.
In
The third part of our invention relates to means for lubricating the faces of the
bricks as they pass round in the cylindrical mould. This has been usually done by
means of a lubricator working in vertical slides, which lubricator is supported on
pins bearing on cam surfaces on the surface of the cylindrical mould. This
arrangement has proved ineffectual owing to the liability of the slides working
loose, which ultimately cause rattling and consequently imperfect lubrication.
order to obviate these disadvantages we mount the lubricator on the end of an arm,
or on the ends of two parallel arms, which arms are fulcrumed on a fixed part of
the framework. On each side of the lubricator we mount a wheel, which wheels
run on cam surfaces on the cylindrical mould, and cause the lubricator to rise and
fall in an even manner as required for lubricating the faces of the bricks in the

page_text: moulds. In this manner the wear and tear of the lubricator is materially reduced,
and the cost of production is much less than that of lubricators at present in use.

Improvements in Machinery for Making and Pressing Bricks and
the like.
We, WILLIAM WILKINSON and HERBERT ALEXANDER, both of Neville
Works, Elland Road, Leeds, in the County of York, Engineers, 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:-
The object of our invention is to improve the construction of brick making aud
pressing machines in such a manner that the said machines shall occupy less room,
while at the same time they shall act more efficiently than those at present in use.
In order that our invention may be clearly understood we will proceed to describe
same with reference to the accompanying drawings, in which similar letters refer
to like parts in all the figures.
Fig. 1 is a side elevation of a machine constructed according to our invention,
and Fig. 2 is a plan of same.
Figs. 3 and 4 are detail views.
The first part of our invention relates to the construction and combination of
parts for transmitting motion from the driving shaft of the machine to the shaft of
the stamping or pressing arrangement. In machines of this type as hitherto
constructed, the motion has been communicated by means of a spur wheel mounted
on the driving shaft, and gearing with a spur wheel mounted on an auxiliary shaft,
which latter by means of bevel gearing has hitherto transmitted the motion to the
shaft of the pressing arrangement. This arrangement is disadvantageous owing to
the necessity of having a bearing on the extremity of the auxiliary shaft, which
causes the driving pulleys of such shaft to be placed further away from the
machine; besides the number of parts contained in such arrangement causes a large
amount of friction, and also much expense in making.
According to our invention we mount a bevel wheel A on the end of the main
shaft B, and we prolong the shaft C of the pressing arrangement, and mount
thereon a bevel wheel D which latter gears with the wheel A mounted on the shaft B.
In this manner we obviate the necessity of employing an auxiliary shaft, and can
thus bring the main driving pulleys E closer to the machine, consequently reducing
the width of such machine considerably.
The second part of our invention relates to the table which receives the bricks
from the cylindrical mould. This table has hitherto been made in one piece, and
owing to the shocks caused by the action of the plunger, such table is liable to be
broken, and in the event of breakage, the cost of renewing the whole table is very
considerable. To overcome these disadvantages, we make our table in three
sections, (see Fig. 3). The first section F of such table we make comparatively
thin, such section F being supported at one end on the bracket V which is attached
to the framework G of the machine. The second section H of the table is made
very deep, as it contains the mould in which the brick is pressed, and this second
section His slidden into position between the plungers J J Fig. 1 on guides G
situated in the main frame G. Lugs H' and H2 are formed on the section H,
the lugs H being for the support of the inner end of the section F to which
it is screwed or otherwise detachably fixed thereto. The third section K is

page_text: comparatively thin like the first section F, and is carried on brackets W on the
framework G, its end resting upon the lugs H' on the centre section, to which it is
screwed or otherwise suitably attached. It will thus be seen that by the
employment of this arrangement of table, should one of the sections become
broken, it can be readily removed and replaced at a small cost.
.
The third part of our invention relates to means for lubricating the faces of the
bricks as they pass round in the cylindrical mould. This has been usually done
by means of a lubricator working in vertical slides, which lubricator is
supported on pins, bearing on cam surfaces on the surface of the cylindrical
mould. This arrangement is disadvantageous owing to the liability of the slides
working loose, which ultimately cause rattling and consequently imperfect
lubrication. In order to obviate these disadvantages, we mount the lubricator L
(see Fig. 4) on the ends of two parallel arms M, which arms are fulcrumed at N
on a fixed part of the framework G. On each side of the lubricator L we mount
a wheel P, which wheels P run on cam surfaces R on the cylindrical mould S, and
cause the lubricator L to rise and fall in an even manner, as required for lubricating
the faces of the bricks in the moulds. The wheels P are carried on the ends of
rods T, which are adjustably connected to the lubricator L. By adjusting the
rods T on the sides of the lubricator, the pad of said lubricator L is adjusted with
reference to the cylindrical mould S, and thus the pressure upon the face of the
bricks may be varied as desired, according to requirements.
The wear and tear of the lubricator is materially reduced by the employment of
the above arrangement, at the same time the cost of production is much less than
that of lubricators at present in use.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of the bevel wheel A, shaft B, shaft C, and bevel wheel D,
substantially as and for the purposes herein set forth.
2. The formation of the table in sections, substantially as and for the purposes
herein set forth.
3. The combination of the section F, section H having lugs Hand H2 thereon,
and the section K forming the table, supported on the framework G by means of
guides G and brackets V and W, substantially as and for the purposes herein
set forth.
4. The lubricator L, carried on the arms M, substantially as and for the purposes
herein set forth.
5. The combination of the lubricator L, arms M, wheels P, cam surfaces R,
cylindrical mould S, and rods T, substantially as and for the purposes herein
set forth.
6. The general arrangement, construction and combination of the various parts
forming improvements in brick making machinery substantially as herein set forth.
