PROVISIONAL SPECIFICATION
Improvements in or connected with Machines for Grinding Pulp,
Dyes, and the like for Paper-making.
GEORGE HIBBERT of 17 The Crescent Gateshead-on-Tyne Engineer in the County
of Durham do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or connected with machines for grinding
pulp, dyes and the like for paper-making
This machine consists of a bed plate, in which are fixed the disc's box or casing,
standards and pedestals for carrying the revolving shafts and discs.
The disc box or casing in which the discs & centrifugal lifter or pump revolves, is
made of cast iron, brass or other suitable metals, with inlets and outlets required.
The discs are made of cast iron, steel, bronze or other suitable metals On the back
of one disc I construct a centrifugal pump, for lifting the back water or other waters
used in the manufacture of pulp or paper, so that they mix with the motorials being
operated upon, as it leaves the discs faces, and so gets thoroughly mixed in the disc
box or casing before discharging.
In the disc with the centrifugal pump 1 fix a solid steel or iron shaft, in the second
disc I fix a hollow shaft "made of steel bronze or other suitable metals," so that the
material being operated upon passes through the hollow shaft into the discs laces
The discs are cach driven in opposite directions, and at different speeds, so as to
keep the materials being operated upon longer in the grinding faces before passing out
of the disc box or casing
The discs are geared with bars or facings, made of steel, iron, bronze or other
suitable metals, and are made either straight on the face or serrated
On the hollow shaft 1 can fix a cone pulley, so that the speed can be regulated to
suit the different materials being operated upon & to regulate the discharge.
The disc and shaft are set or adjusted by means of a screw and nut working in a
pedestal in which the thrust collars of the shaft revolve.
The disc with the solid shaft is kept in its place by collars working in a pedestal
made fast to a stand

Improvements in or connected with Machines for Grinding Pulp,
Dyes, and the like for Paper-making
GEORGE HIBBLRT of 17 The Crescent Gateshead-on-Tyne Engineer in the County
of Durham 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.-
This invention relates to improvements in a combined pulp refining engine and
water mixor and lilter used in the art of pulp and paper making and for the like
purposes, such as mixing and grinding colours, dyes and other materials for paper
buld making.

This machine consists of a bed plate A, on which are fixed the disc's box or casing,
standards and pedestals for carrying the revolving shafts and disc's.
The disc box B or casing in which the discs and centrifugal lifter or pump revolves,
is made of cast iron, brass or other suitable metals with inlets C and C, and outlet D
The disc's E and F are made of cast iron, steel, bronze or other suitable metals.
On the back of one disc F, 1 construct a centrifugal-pump Ffor lifting the backwater
or other waters used in the manufacture of pulp or paper, so that they mix with the
materials being operated upon as its leaves the disc's faces E and F and so gets
thoroughly mixed in the disc box or casing B before discharging,
In the disc with the centrifugal pump on I fix a solid steel or iron shaft, in the
second disc EI fix a hollow shaft C made of steel, bronze or other suitable metals, so
that the material being operated upon passes through the hollow shaft into the disc s
face=.
The disc's are each driven in opposite directions, and at different speeds so as to
keep the materials being operated upon longer in the grinding faces before passing out
of the disc box or casing. The disc's E and F are geared with bars or facings M N
made of steel, bronze, on, or other suitable metals, and are made either shinight
on the face o serrated, and are fit in a groove at each end and fastened by means of
wood dividers driven in as keys as shown in Figs 3 and 4.
On the hollow shaft C1 can fix a cone pulley so that the speed can be regulated to
suit the different materials being operated upon and to regulate the discharge
The dise E and shaft are set or adjusted by means of a screw and nut G working
in a pedestal in which the thi ust collars H of the shaft revolve
The disc F with the sohd shaft is kept in its place by collars working in a pedestal
made fast to stand 1.
Having thus particularly described and ascertained the nature of my said
invention and what manner the said as performed, I declare that what I
claim is :-
1st. In an engine for refining or mixing paper pulp or other materials the employ-
ment of a casing containing two revolving disc's mounted on shafts, and working in
opposite directions, by which means the material being operated upon is kept longer
in the faces.
2nd The use of a centrifugal pump on the back of one of the disc's for the purpose
of lifting the backwater or other waters used in the manufacture of paper, and better
mixing with the stuff's being operated upon.
3rd. The use of a hollow shaft by which means the material being operated upon 15
conveyed direct into the faces and so as-ures of the stuff being operated upon Defore
being discharged
