Paper.
We, ROGER DUXBURY DUXBURY of the Firm of Yates Duxbury and Sons of
Heap Bridge Paper Mill, Bury, and Hall-i'th'-Wood Paper Mill, Astley Bridge
near Bolton, Paper Manufacturers, and CHARLES ROBERT SEDDON of 285 Roch-
dale Road, Bury, Manager, all in the County of Lancaster, do hereby declare the
nature of our said invention to be as follows:-
This invention refers to improvements in or relating to collar-gangs or roller
grinding mills, poaching or beating engines employed for making paper and consists
in means whereby wood pulp, sulphite, soda or pine and other woods and the like
are torn up to facilitate the working or conditioning of the same to reduce time and
labor. This we carry into effect by smashing or breaking up the said pulp before
passing to the various machines by means of angular pointed or serrated rollers
driven at varying speeds by suitable gearing. The angular pointed or serrated
metallic rollers are fixed on centres mounted in bearings in suitable framework.
On the back side of the said rollers are mounted angular or other doctors to direct
and deliver the treated material or substance to the machine in which it is to be
operated upon. The wood pulp, sulphite, soda or pine and other woods and the
like is fed to the rollers by means of an endless belt, felt, or canvas carried over or
round rollers and operated in any convenient manner from the machine or otherwise.
To ensure of the treated material or substance being delivered to the collar-gang,
poaching or beating engine another endless belt, felt, or canvas may be employed
and driven from any convenient position.

and deliver the treated material or substance to the machine in which it is to be
operated upon. The wood pulp, sulphite, soda or pine and other woods and the
like is fed to the rollers by means of an endless belt, felt, or canvas carried over or
round rollers and operated in any convenient manner from the machine or otherwise.
To ensure of the treated material or substance being delivered to the collar-gang,
poaching or beating engine another endless belt, felt, or canvas may be employed
and driven from any convenient position.
Fig. 1 is a side elevation of our invention-Fig. 2 an end view, and Fig. 3 an
end view of angular pointed or serrated rollers.
Wood pulp, sulphite, soda or pine and other woods and the like are placed by
the attendant on the endless belt, felt, or canvas A, which delivers the same to the
angular pointed or serrated rollers B and C driven at varying speeds by the spur
wheels D and E. The angular pointed or serrated rollers B and C are fixed on
the centres F and G and are mounted in the bearings H and I on the frames J.
On the back side of the rollers B and C are attached to the frames J the angular
doctors K to direct and deliver the wood pulp, sulphite, soda or pine or other
woods and the like to the pan K' of the collar-gang or roller grinding mill to be
operated upon by the ordinary revolving rollers. The endless belt, felt, or canvas A
18 carried over or round the rollers L and M rotated by the belt N and pulleys O
and P. After the wood pulp, sulphite, soda or pine and other woods has passed
through the rollers B and C and been thoroughly broken up falls on the endless
belt, felt, or canvas R which passes round the rollers S and T. The rollers L
and S are mounted on centres in the slotted fixings V to allow of the endless belts,
felts, or canvases A and R being kept at an uniforın tension. The shaft W is
driven by the pulley Y from any convenient position. On the shaft W is fixed the
spur wheel X which gears into the spur wheel Z on the shaft G.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with collar-gangs or roller grinding mills, poaching or beating
engines employed for making paper the use of the serrated rollers B and C, the
travelling endless belts, felts, or canvases A and R and the doctors K, substantially
as described and illustrated in the drawings.
2. The general arrangement, construction, and combination of parts composing
our improvements in or relating to collar-gangs or roller grinding mills, poaching
or beating engines employed for making paper, as hereinbefore described and as
illustrated in the annexed drawings.
