Improvements in Brickmaking and Pressing Machines.
I, WILLIAM JOHNSON, Engineer Castleton Foundry, Armley, Leeds, in the
County of York, 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:―
My invention relates to improvements in the method of pressing bricks, and
consists of mechanism for delivering the bricks on to the press table, and feeding
them into the press mould edgeway, instead of the usual method of delivering and
feeding them flatway.
The object of my invention is by pressing the brick edgeway to produce a higher
class and more perfect pressed brick of the ordinary type.
The brick is usually formed flatway in the mould of the brickmaking machine,
that is the pressure due to the worm or other appliance used for filling the mould
is laid on flatway of the brick, and when the brick is also pressed flatway the grain
or lamination remains the same. This is objectional in some classes of clay, as the
bricks crack on the lines of lamination when drying and thereby cause waste and
reduce the production. By the use of my invention I destroy the lines of
lamination in the brick entirely and produce a sounder and more uniform pressed
brick throughout.
For the purpose of more fully describing the improvements in my invention
reference is made to the accompanying drawings.
(Fig. 1) is a front elevation of the feeding motion for a brickmaking and pressing
machine. (Fig. 2) is a side elevation of the same.
(Fig. 3) is a plan of the travelling table J.
In order to carry out the object of my invention the mould A (Fig. 2) in which
the brick is formed, is placed in a suitable position on the brickmaking machine to
be above the press table Q. and is arranged to deliver the brick B edgeway up, on
to a stationary table C level with the bottom edge of the mould. The brick
remaining on the table C is prevented from falling below the level of the travelling
table J. until the next brick delivered from the mould pushes it off on to the
travelling table J. which is made high enough to be on a level with the table C.
and to receive the brick the same way up as delivered from the mould. The
travelling table J has a reciprocating motion imparted to it by means of the rod S
connected to the bottom end of the lever F. The lever F is connected at the top
end to the eccentric rod E which is actuated by the eccentric D keyed on to the
crank shaft T appertaining to the press. The travelling table J is timed on its
backward stroke to reach and receive the brick as it is pushed off the table C by
the next brick delivered from the mould A. A suitable stop P is fixed in a convenient
position to prevent the brick moving back with the travelling table, and allows the
said table to slide under the brick and drop it below on to the table Q appertaining
to the press. The brick remains in this position until the travelling table is on its
return stroke towards the press when it is carried or pushed in front of the said
table, and fed into the press mould R remaining on its edge the same way as it was
delivered from the mould A. The mould R is made to suit the size and the shape
of the brick when flatway, and after being pressed the brick is also delivered
flatway or the reverse way from that in which it was fed into the mould. The
brick when delivered from the press mould is pushed away to the front of the table
by the next incoming brick. By this method of pressing bricks the formation of
the brick as formed in the brick mould is entirely destroyed and reformed again
in the press mould to the required shape and size.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. The construction of a feeding motion for feeding bricks from the mould of a
brickmaking machine to the mould of a brick pressing machine edgeway up,
substantially as herein described and illustrated.
2nd. The use of a stationary table C for preventing the brick falling below the
level of the travelling table J when delivered from the mould A substantially as
herein described and illustrated.
3rd. The construction of a travelling table J constructed to travel or move in a
line with the bottom edge of the mould of a brickmaking machine, substantially as
herein described and illustrated.
Dated this the 31st day of January 1894.
