LMPROVEMENTS IN BRICKMAKING AND PRESSING MACHINES
Year: 1884

page_text: I, TOM PALMER, of 4, Moor View Dewsbury Road, Leeds, in the County of York,
Brickmaker, do hereby declare the nature of said invention for "LMPROVEMENTS
IN BRICKMAKING AND PRESSING MACHINES, to be as follows:-
In Brickmaking and pressing machines it is customary to use oil for lubricating
the parts known as "plates," and to apply steam or other heating medium to the
feeding rammers and pressers, and in practice when a machine has ceased to be
worked for a time, there is danger on re-starting, of its breaking down through
extra and unnecessary strain upon it caused by the hardening of the material
employed by the action upon it of the steam or other heating medium.
Now my invention is designed to enable such use of lubricant and steam or
other heating medium to be dispensed with, thereby not only reducing the cost but
improving the quality of the bricks.
To this end I face the parts known as "plates" in the cylinder and also on the
feeding rammers and pressers in such machines as above referred to, with sheet
india-rubber to prevent adhesion to the said parts, of clay or other material of
which bricks are to be made.

I, TOM PALMER, of 4, Moor View, Dewsbury Road, Leeds, in the County of York,
Brickmaker, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN BRICKMAKING AND PRESSING MACHINES," and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:
In brickmaking and pressing machines it is customary to use oil for lubricating
the parts known as "plates," and to apply steam or other heating medium to the
feeding rammers and pressers, and in practice, when a machine has ceased working
for a time there is danger in re-starting, of its breaking down through extra and
unnecessary strain upon it caused by the hardening of the material employed, by
the action upon it of the steam or other heating or drying medium.
Now my invention is designed to to enable auch use of lubricant and steam or
other heating medium to be dispensed with, thereby not only reducing the cost but
improving the quality of the bricks.
To this end I face the parts known as "plates," in the cylinder, and also the
feeding rammers and pressers in such machines as above referred to, with sheet
india-rubber to prevent adhesion to the said parts, of clay or other material of
which bricks are to be made.
In the accompanying drawings, Fig. 1. is a front view of a "plate" for the
cylinder of a brickmaking machine. Fig. 2. is a cross-section, and Fig. 3, a
horizontal or longitudinal section of the same, shewing the india-rubber a, attached
to the face thereof, according to my invention.
Fig. 4, is a sectional plan in part, and Fig. 5, is a front view of the back or
feeding rammer shewing the india-rubber a, attached thereto. Fig. 6, is a
longitudinal section, and Fig. 7. a face view of a presser also with india rubber
attached.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
In brickmaking and pressing machines, the use of india rubber attached to the
working faces of the plates in the cylinder or mould, and also to the faces of the
feeding rammers and pressers substantially as and for the purpose bereinabove
described and shewn in the drawings.
Dated this 16th day of June 1885.
