An Improved Machine or Apparatus whereby Fibrous Materials
such as Esparto Grass may be Reduced to Pulp for Paper
Making and other Uses.
I, GEORGE HENRY MALLARY, of 18 Tavistock Street, Bedford Square, in the
County of Middlesex, Paper Mill Engineer do hereby declare the nature of this
invention to be as follows
This invention has for its object the arrangement of an improved machine or
apparatus whereby fibrous materials such as esparto grass may be reduced to pulp for
paper making and other uses without grinding or reducing them to a powdered or
finely divided state, as is the case with the ordinary beating engine, but so that a
certain length of fibre may remain in the stuff when passed through the machine or
apparatus, at the same time that they are opened out or separated, whereby a stronger
and superior paper may be produced from inferior materials, and the strength,
toughness, and flexibility of the fibres, especially in the case of esparto grass, may be
greatly increased by its use.
In carrying my improved machine or apparatus into practical effect I take a shaft
of metal of a suitable length and diameter on which at or near one extremity I attach
a circular plate of metal on the exterior edge of which I form a suitable number of
slots or grooves at a suitable angle to the line of motion, and in these slots or grooves
I place and firmly attach, blades of steel or other suitable metal, in order that when
a rotary motion is given to the said shaft and circular plate, a screwing or propelling
action may be obtained, and thereby force the prepared stuff through the length of
the apparatus. Next to this circular plate I place on the same shaft or axis, a disc of
wood, metal or other suitable material, to act as a distance piece between the said
circular plate and the circular disintegrator plate or disc which is formed with serrated
or indented edges and so continue to place alternately a distance piece and a
disintegrator plate until the required number are mounted and the parts and shaft are
then placed in the cylinder or case in which they work.
The cylinder or case is made in two parts, divided longitudinally with the ends and
the lower halves of the bearings for the shaft formed or cast thereon.
At one end of

page_text: the shaft a driving pulley is attached so that on motion being given to the same, the
whole of the parts revolve together, and the circular plate with the screw blades
propels or causes the stuff to flow to the end, passing between and amongst the
disintegrating plates, and being thereby opened out, separated, and prepared or
reduced to the required state for passing over the paper machine or be applied to
other uses.
The stuff to be disintegrated is fed at one end into the apparatus from a tank or
reservoir through a pipe or passage provided with means for controlling and regulating
the flow, and the other end of the apparatus, case, or cylinder is also provided with
means for controlling and regulating the outlet.

An Improved Machine or Apparatus whereby Fibrous Materials
such as Esparto Grass may be Reduced to Pulp for Paper
Making and other Uses.
I, GEORGE HENRY MALLARY of 10 Tavistock Street Bedford Square in the
County of Middlesex, Engineer 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, reference being had to the accompanying
sheet of Diagrams and to the letters and figures marked thereon, that is to say:-
This invention has for its object, the production of an improved machine or apparatus,
whereby fibrous materials, such as esparto grass, may be reduced to pulp for paper
making and other uses, without injury to the fibre, and so as to produce it in longer
lengths, and cleaner, without breaking or grinding it to a powder.
In carrying my improved machine or apparatus into practical effect, I take a shaft
of metal of suitable length and diameter, on which at one end or extremity I attach a
circular plate, on the exterior edge of which I form a suitable number of. slots or
grooves at a suitable angle to the line of motion and in these slots or grooves I place
and firmly attach blades of steel or other suitable material two, three, four, or more in
number, in order that when rotary motion is given to the said shaft and circular plate
a screwing or propelling action may be obtained, and thereby force the prepared stuff
through the length of the apparatus, exposing it while passing to the action of the
serrated disintegrator plates or discs, which open out, clean and prepare the fibre or
material fed into the apparatus. Next to this circular plate I place on the same shaft
or axis, a disc of wood, metal, or other suitable material to act as a distance piece
between the said circular plate and the disintegrator plate or disc, which is formed with
serrated or indented edges and so continue to place alternately a distance piece and a
disintegrator plate or disc, until the required or desired number is mounted on the
shaft, and the shaft and the parts are then placed in the cylinder or case in which
they work.
The cylinder or case is made in two parts divided longitudinally, with the ends and
the lower halves of the bearings or supports for the shaft, formed or cast thereon, or
attached thereto, at one end of the shaft a suitably sized driving pulley is placed so
that on motion being given to the same, the whole of the parts revolve together,
and the circular plate with screw blades propels or causes the stuff to flow to the end
passing between and amongst the disintegrator plates and being thereby opened out,
separated, and prepared or reduced to the required state for passing over the paper
machine or be applied to other uses.
The stuff to be disintegrated is fed into one end of the machine or apparatus through
an opening which is provided with suitable means of control and regulation from a
tank or reservoir through a suitable pipe or passage, and at the other end the outlet
is placed which is also provided with suitable means for controlling and regulating the
outflow.

page_text: In some cases I may cast or form the cylinder or case in one piece, and insert
or withdraw the interior part in a similar manner to a piston in a pump or engine
cylinder but in any case I turn out or bore it so as to obtain an even and smooth
Burface.
In order that my invention may be more clearly understood I have provided the
accompanying sheet of diagrams with letters of reference marked thereon, similar parts
being denoted by the same letters in each Figure; Figure 1 being a longitudinal
elevation and part section showing the interior, and Figure 2 a cross section.
a is the shaft which works or rotates in the cylinder or case e e with the driving
pulley a¹ at the end.
bis the circular plate with slots or grooves formed in it into which the blades
of steel or other suitable material are placed or fitted, and firmly attached.
ce the distance pieces of wood or other suitable material which keep the serrated
disintegrator or beater plates or discs, at the required distance from the slotted plate
and each other.
dd the serrated disintegrator or beater plates or discs, of which there may be
any suitable number according to the size of the machine or apparatus or other
requirements.
ee the cylinder or case in which the shaft and its attached parts work.
ff the bearings formed in one with, or firmly attached to, the lower half of the
cylinder or case e e.
the inlet pipe, passage or entrance, to the interior of the machine or apparatus,
through which the prepared fibre enters, and is provided with a sluice valve or other
suitable means for controlling and regulating the flow of the pulp or shutting it off
.altogether.
h the outlet passage, pipe, or exit from the interior of the cylinder or case, provided
with a sluice valve or other suitable means for controlling and regulating the outflow
of the pulp or shutting it off altogether.
kk the stand or support for carrying the cylinder and apparatus when such is
used or it may be arranged and formed in any other suitable and convenient
manner.
Figure 2 represents in section an end view or cross section of the machine or
apparatus to show the interior.
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
1 claim is
The arrangement and combination of parts forming the machine or apparatus
hereinbefore described, and acting in the manner and for the purposes herein set forth,
and as shown in the accompanying sheet of diagrams and any mere modification
