PROVISIONAL SPECIFICATION.
Improvements in Brickmaking Machinery.
We, WILLIAM WARD AND SONS LIMITED, Engineers, of Clark Lane
Brickworks, Leeds, in the County of York, and WILLIAM WARD, of the same
place, Engineer do hereby declare the nature of my said invention to be as
follows:
The improvement herein referred to primarily relates to the machine known as
Ward's "Clot-rolling" machine, and for which Letters Patent No. 4674 were
granted to Henry, John, and William Ward, on the 2nd December 1876.
"clot
"
This invention may also be applied to other forms of brickmaking machinery.
The invention consists of an apparatus for cutting off to any desired length, the
or bar of clay, and is designed to supersede the vertical knives and cutting
wires now used on Ward's and other machines and " cutting-off tables." On or
over the table or plate on which the clay bar is propelled or delivered we mount, on
suitable shafts or spindles two drums having blades or knife-plates inserted in their
peripheries. These two cutting-off drums are suitably geared together. They
revolve horizontally when the bar of clay is propelled against them, and in so.
revolving, one blade of each is forced into the clay, and meet or almost meet one.
another on the middle of it. As the cutting-off drums are further revolved by more
clay being brought against the next pair of blades, the receding blades carry
forward the piece of clay that has been cut off.

COMPLETE SPECIFICATION.
Improvements in Brickmaking Machinery.
We, WILLIAM WARD
AND SONS LIMITED, Engineers, of Clark Lane
Brickworks Leeds in the County of York and WILLIAM WARD of the same
place, Engineer, do hereby declare the nature of our said invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The improvement herein referred to primarily relates to the machine known as
Wards ""
Clot-rolling" machine, and for which Letters Patent No. 4674 were
granted to Henry, John and William Ward on the 2nd December 1876.
This invention may also be applied to other forms of brickmaking machinery.
The invention consists of an apparatus for cutting off to any desired length, the
"clot ""
or bar of clay, and is assigned to supersede the vertical knives and cutting
wires now used by Wards and other machines and "cutting off tables." On or over
the table or plate on which the clay bar is propelled or delivered we mount on
suitable vertical shafts or spindles two drums having blades or knife plates inserted
in their peripheries. These two cutting off drums are suitably geared together.
They revolve when the bar of clay is propelled against them, and in so revolving,
one blade of each is forced into the clay, and these meet or almost meet one another
in the middle. As the cutting-off drums are further revolved by more clay being
brought against the next pair of blades, the receding blades carry forward the piece
of clay that has been cut off.
And in order that our said invention may be particularly described and

page_text: ascertained reference is hereby made to the accompanying urawings,
similar letters of reference indicate corresponding parts.
Fig 1 is a front elevation and Fig. 2 a plan of our invention.
a a are two parallel shafts. bb are the bosses of the drums c c, loose on the
shafts. dd are toothed wheels of equal diameter, both fast on the bosses b b and 5
geared together so as to revolve with the drums simultaneously in opposite
directions. e e e. are three cutting blades or knife plates fitted to each drum, as
shewn in the drawings. f is the table or plate on or over which the clay bar is
delivered.
When a clot or bar of clay is pushed forward, its contact with the blades causes 1
the drums and blades to revolve and penetrate the clay, nearly severing it. The
further revolution of the drums causes the receding blades to entirely sever and
break away a certain specified piece of clay from the travelling clot; the cutting
and delivery of such pieces of clay being continued so long as the clot is fed into
the apparatus.
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. In brick making machinery, the improved method and means of and for cutting
and severing the clots or bars of plastic clay, to any desired lengths, substantially as
and for the purposes hereinbefore described and illustrated by the drawings.
2. The general construction, arrangement and combination of the several and
respective parts, together forming our invention of improvements in brick making
machinery, substantially as and for the purposes ɓereinbefore described and
illustrated by the drawings.
