PROVISIONAL SPECIFICATION.
Improvements in Engines for Washing, Breaking, and Beating
Paper Pulp.
I ALFRED CANNON, of Sandford on Thames, in the County of Oxford, Paper
Maker do hereby declare the nature of this invention to be as follows:-
~:
This invention relates to improvements in engines for washing, breaking and
beating paper pulp, and is designed to reduce the amount of power required to
drive the engine to increase the range of materials it will successfully treat-such
as to enable it to treat such coarse material as long rags, rope and the like matter,
which would clog existing beaters; breaking and beating as well as washing
them.
In carrying out my invention I provide a tub or pulp containing vessel which
may be of somewhat ordinary form--substantially straight sides, and feather and
rounded ends.
In one portion of the chaunel formed in this tub is mounted and fitted a washer
drum, and at another point is arranged a lifter drum narrower than the tub
channel and working in a casing of correspondingly reduced width.
This casing
forms a curved passage up which the liquid and pulp material is lifted by the
blades of the lifter drum. Each blade is appropriately shaped for its work and I
find that a blade consisting of a radial plate filled in with a triangular filling piece
answers well. This lifter delivers the pulp to an incline, down which it runs to
the beater plate and beater whence it flows again into the tub.
The beater is adjustable relatively to the plate and the other parts are suitably
mounted and driven.
The necessity for washing and partial preparation in a separate machine before
proceeding with the beating operation is avoided.
Dated the 22nd day of March 1894.

Maker 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 :-

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 shews by a side view my improved paper pulp engine and
Fig. 2 shews the same by a plan view.
-
The tub of the engine is shewn with a small portion broken away at one end for
convenience of the drawings.
In carrying out my invention I provide a tub or pulp containing vessel a which
may be of somewhat ordinary form-substantially straight sides a' a' mid-feather a²
and rounded ends a³ a³.
In one portion of the channel b formed in this tub a is mounted and fitted a
wasber drum c and at another point is arranged a lifter drum d narrower than the
tub channel 6 and working in a casing e of correspondingly reduced width.
This casing e forms a curved passage e' up which the liquid and pulp material is
lifted by the blades d' of the lifter drum d. Each blade d' is appropriately shaped
for its work and I find that a blade consisting of a radial plate d² filled in with a
triangular filling piece d³ answers well. This lifter d delivers the pulp to an
incline down which it runs to the beater plate g and beater h whence it flows
again into the tub.
The beater h is adjustable relatively to the plate g by suitable adjusting apparatus
here shewn as a lever i carrying the axis of the beater and centred at i
capable of being raised or lowered by means of an adjusting screw i². The other
parts are suitably mounted and driven.
The necessity for washing and partial preparation in a separate machine before
proceeding with the beating operation is avoided.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. The construction and arrangement or combination in a tub of a drum washer,
lifter wheel, and beater with suitable supporting and driving mechanism, all
substantially as and for the purpose set forth.
2. The combination or arrangement and use of an engine for washing, breaking,
and treating paper pulp so as to reduce the driving power required, increase the
range of materials treated, and avoid necessity for separate washing and partial
preparation, all substantially as and for the purposes hereinbefore set forth.
Dated the 22nd day of December 1894.
