PROVISIONAL SPECIFICATION.
Improvements in Breaking and Beating Engines, such as are used in
Making Paper Pulp and for like purposes.
I, JAMES HUNTER ANNANDALE, of Polton Paper Works, Polton, in the
County of Mid Lothian, North Britain, Paper Maker, do hereby declare the
nature of this invention to be as follows, that is to say:-
My said invention relates to breaking and beating engines which are to some
extent of the kind described in my Patent Specification No. 9106 of 1888, and my
present object is to improve such engines and render them more efficient.
A breaking or beating engine of the kind referred to is made with a roll of a
conical form and which works in a conical casing, the roll being armed with knives,
and knives or bars being fixed in the casing. In carrying out my present invention
the roll and casing are placed with their axis vertical and their larger ends down-
wards. The fibrous materials are put into a feed trough or hopper at the top of
the casing which is flared outwards in form at about the top of the roll, and water
is admitted through perforations at or near what may be termed the neck of the
casing. The materials after being operated on between the roll and casing pass
off from the bottom by a pipe or passage extending up above the level of the water
within the casing, or to a higher or lower level if found desirable, such pipe or
passage being provided with a sluice or valve for regulating the rate of discharge.
The shaft of the roll, which may be driven from above or from below is adjustable
vertically for varying the distance between the knives of the roll and those of the
casing. This vertical adjustment may be effected by means of screws or levers,
and the weight of the roll and its shaft may be more or less counterbalanced.
.
The improved construction has the advantage of an open feed compartment, and
avoids obstruction from over feeding as the materials will be taken down only in
proportion as the machine passes them through.
Dated this Thirteenth day of May 1892.

COMPLETE SPECIFICATION.
Improvements in Breaking and Beating Engines, such as are used in
Making Paper Pulp and for like purposes.
I, JAMES HUNTER ANNANDALE, of Polton Paper Works, Polton, in the
County of Mid Lothian, North Britain, Paper Maker, do hereby declare the
nature of this invention and in what manuer the same is to be performed, to be
particularly described and ascertained in and by the following statement, that is
to say :-
My said invention relates to breaking and beating engines which are to some
extent of the kind described in my Patent Specification No. 9106 of 1888, and my
present object is to improve such engines and render them more efficient.
In carrying out my present invention the breaking or beating engine is made
with a conical roll and casing placed with their axis vertical but with their larger
ends downwards. A feed trough or hopper is provided at the top of the casing
which is flared outwards in form at about the top of the roll, and water is admitted
at or near what may be termed the neck of the casing. The materials after being
operated on pass off from the bottom of the casing by a pipe or passage extending
up to any desired level and fitted with a sluice or valve.

page_text: And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing my improvements.
Figure, 1, on the accompanying sheet of drawings is a vertical section of a
breaking or beating engine as made with my present improvements,
Figure, 2, being a horizontal section of the casing.
As shown in the drawings the breaking or beating engine is of the kind having
a conical roll, A, which works in a conical casing, B, the roll, A, being armed with
knives, C, and knives or knife bars, D, being fixed in the casing, B. In carrying
out my present invention the roll and casing are placed with their axis vertical and
their larger ends downwards. The fibrous materials are put into a feed trough or
hopper, E, formed or fixed at the top of the casing, B, which is flared outwards in
form at about the top of the roll, A. Water is admitted through perforations in a
pipe, F, encircling the casing, B, near what may be termed the neck of the casing.
The materials after being operated on between the roll, A, and casing, B, pass off
from the bottom by a pipe, G, extending up to the level of the water within the
casing, or to a higher or lower level if found desirable, such pipe, G, being provided
with a sluice or valve, H, for regulating the rate of discharge. The shaft, J, of
the roll, A, is fitted with a belt pulley, K, and the footstep bearing, L, is connected
to an adjustably counterweighted lever, M, which is connected to a rod, N, having
on its upper end a screw hand wheel, P, by turning which the shaft, J, is adjusted
vertically for varying the distance between the knives, C, of the roll, A, and the
knives, D, of the casing, B.
The improved construction has the advantage of an open feed compartment and
avoids obstruction from overfeeding as the materials will be taken down only in
proportion as the machine passes thein through.
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. In breaking and beating engines, placing the conical roll and casing with
their axis vertical and their larger ends downwards substantially as and for the
purposes herein before described.
2. In breaking and beating engines, the combination and arrangement of a
conical roll and casing placed with their axis vertical and their larger ends down-
wards; a feed trough or hopper at the top of the casing; water supply inlets at or
near the neck of the casing; and a discharge pipe or passage extending up from
the bottom of the casing to any desired level and fitted with a sluice or valve, all
substantially as and for the purposes hereinbefore described.
Dated this Ninth day of February 1893.
