1, AARON GIBBS of Arlesey Station-Gault Brick Works,.Arlesey Bedfordshire,
Manager do hereby declare the nature of this invention to be as follows :-
:--
The object of my invention is to facilitate and expedite the operations of
preparing the clay for brick moulding. by machinery.
To effect this employ an apparatus consisting of two rolls on which a series of
rings are securely fixed side by side, the said rings having projections or teeth less
than half the width of the ring on one-side, while the other side is plain. These
rings are so fixed that they can easily be removed from the rolls if necessary,
The said rolls are placed in suitable bearings in such a position that the
projections or teeth on the rings of one roll come opposite the plain part of the
rings on the other roll, the bearings are adjustable so that the rolls can be so
moved that the space between the projections or teeth and the plain surface may be
altered to suit the different kinds of clay and the required fineness of the said
material when ground.
The two rolls are so geared that one of them revolves a little quicker than the
other thus facilitating the grinding of the clay and also preventing the rolls from
wearing unevenly.
A hopper is placed above the rolls in such a position that the clay falls on to the
rolls and is drawn in by the toothed rings and ground between them and the smooth
ones, to prevent the rolls becoming clogged; suitable scrapers are so fixed that the
rolls are cleaned as they come under the hopper thus insuring a constant feed, and
the clay is broken or ground properly and not crushed between the rolls: The
whole is driven by suitable gearing and is mounted on a strong frame and can
easily be placed in a convenient position for feeding the brick-making machine.

Manager 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 my invention is to facilitate and expedite the operations of
preparing the clay for brick moulding by machinery.
To effect this I employ an apparatus consisting of two rolls on which a series of
rings are securely fixed side by side the said rings having projections or teeth less
than half the width of the ring on one side while the other side is plain. These
rings are so fixed that they can easily be removed from the rolls if necessary. The
said rolls are placed in suitable bearings in such a position that the projections or
teeth on the rings of one roll come opposite the plain part of the rings on the other
roll, the bearings are adjustable so that the rolls can be so moved that the space
between the projections or teeth and the plain surface may be altered to suit the.
different kinds of clay and the required fineness of the material when ground.

A hopper is placed above the rolls in such a position that the clay falls on to the
rolls and is drawn in by the toothed rings and ground between them and the
smooth ones, to prevent the rolls becoming clogged suitable scrapers are so fixed
that the rolls are cleaned as they come under the hopper thus insuring a constant
feed, and the clay is broken or ground properly and not crushed between the rolls,
the whole is driven by suitable gearing and is mounted on a strong frame and can
easily be placed in a convenient position for feeding the brick making machine.
And in order to explain my said invention more fully I will now proceed to
describe the same with reference to the accompanying sheet of drawings in which
Fig. 1 shews an end elevation of my improved machinery Fig. 2 plan thereof and
Fig. 3 section to an enlarged scale of a portion of the ring. shewing 3 teeth.
Similar letters of reference are employed in all the views to denote the same parts.
a shews bed of machine on which are holted the plumber blocks c c and d in
which latter the driving shaft g revolves and the blocks ee support the shafts on
which the rolls a² a are mounted. The rolls a a have rings bfixed thereto such
rings being provided with teeth as shown in Fig. 1. On the shaft g is keyed a
pinion e engaging with a toothed wheel e' keyed on shaft that carries one of the
rolls a' on the other end of this shaft is keyed another toothed wheel e engaging
with a toothed wheel keyed on to the shaft that carries the other roll a' the said
toothed wheels being of such sizes that one roll shall revolve a little quicker than
the other.
(spaces
It will be seen at f Fig. 3 that the spaces between the teeth of the rings bare
formed triangular in section to prevent clogging of the teeth I would here remark
that the plumber blocks are made adjustable so as to increase or diminish the
space between the two rolls as required...
