I 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 the construction of Rag Engines for
washing, bleaching, beating, pulping shredding, mixing of various materials and
fibrous substances used in paper pulp and for other like purposes, or for grinding
colours, dyes, paints and other matertals. This Machinery consists of a Tank or vessel
at one or both ends of which I place a revolving Disc plate made of Cast iron, steel or
other suitable materials in which are fixed bars or rubbers made of steel, chilled or cast
iron, bronze or any other materials, and which act on a circular plate composed of
thin steel bars or other materials, and fixed opposite the above named disc, or in place
of a revolving disc a roll fitted with centrifugal lifters, or made as a beater roll may
be used. In the tank or vessel after the disc or roll I place a beater roll or rolls set
with knives or rubbers around its periphery to be used in combination of fixed bars
or blades made of stone or other suitable material so that the pulp or other substances
in circulation from a roll or disc discharging over the top can be acted upon while
passing into the tank or vessel. At the end of the roll or rolls I leave a space of a
few inches and fix thereon one or more centrifugal blades, to discharge any stuff
coming from the disc or roll faster than can pass under the top beater roll or rolls.
The bearings of the shafts of both the revolving disc and the rolls are constructed
with a water space through them, to keep them cool so that the disc and roll or rolls
can be run at a very high speed to do their work better and more quickly. The disc
or roll can be regulated by any of the well known means of screws or levers.

I GEORGE HIBBERT of 17 The Crescent Gateshead-on-Tyne in the County of Durham
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 :—
This Invention relates to Improvements in the construction of Rag Engines for
washing, bleaching, beating, pulping, shredding, mixing of various materials and
fibrous substances used in Paper Pulp; and for other like purposes.
In order that my invention may be fully understood I describe the accompanying
drawings.
Fig. 1 is a side elevation, Fig. 2 a plan, Fig. 3 an end elevation.
This machinery consists of a vessel A of any convenient shape, at one or both ends
of which I place a revolving disc plate B made of cast iron, steel, or other suitable
material which is fitted with bars or rubbers C made of Steel, Chilled Cast Iron, Bronze
or other material, which acts on a circular plate D made of steel, iron, or other material
fitted with bars or rubbers Cas before mentioned on disc B.
Or in place of the revolving disc B a roll fitted with centrifugal lifters or made as a
beater roll may be used.
In the tank or vessel A after the disc or roll I place a beater roll E or rolls fitted
with bars or rubbers F on its periphery to be used in combination with bedplate G of
fixed bars or rubbers of steel, stone or other material so that the pulp or other
substances in circulation from the roll or disc B discharging in direction of arrows
can be acted upon while passing into tank or vessel A. At the end of roll E or
rolls I leave a space and fix thereon one or more centrifugal arms or blades H to
discharge any material coming from disc or roll faster than can pass under top beater
roll E or rolls.
The bearings of the shafts of revolving disc B and Roll E or Rolls are constructed
with a water space I through or around them to keep them cool so that they can be run
at a high velocity to do their work more quickly and can be regulated by any well
known means of screws or levers.
Roll E or Rolls may be driven by wheels belts or Ropes.
Having thus stated the nature of my invention and described the manner of per-
forming the same, I wish to remark that I do not intend to limit myself to the details
given as the same may be varied or modified according to the nature of the material to
be operated upon.
I claim first the use of a revolving roll or disc fit with bars or facings and acting in
combination with fixed bars or facings for pulping or grinding fibrous and other
materials as shewn and described.
Secondly. The use of a roll or rolls to be used as the stuff travelling from the disc
to the tank fit with bars or rubbers as described, working on a bed plate or stone.
Lastly. All the bearings to have water space through the brasses as described:
In witness whereof, I, the said George Hibbert have hereunto set my hand
and seal this first day of December one thousand eight hundred and eighty six.
