the Commissioners of Patents, with his Petition, on the 10th November
1864.
I, LEONARD COOKE, of Horwich, in the County of Lancaster, Paper Manu-
facturer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF PAPER, AND IN THE MACHINERY EMPLOYED THEREIN,
ALSO IN THE MANUFACTURE OF PAPER. CLOTH AND WOVEN FABRICS," to be as
follows:-
The nature of my Invention consists, first, in applying friction to paper in
its damp state immediately after it has left the endless wire gauze of the paper.
machine. The friction may be given by substituting friction rolls for the-
ordinary press rolls, or applying friction rolls between the ordinary press rolls,.
or before the ordinary drying cylinders, or after the paper has passed one or.
more drying cylinders, but while still damp, the object being to remove or
partially remove the inequalities of the paper, and to obtain an even surface-
on the paper before it is finally dried.
Another part of my Invention consists in subjecting the paper either on>
leaving the endless wire gauze of the paper machine, or at any subsequent.
period, but by preference before the paper arrives at the glazing calender or
sizing machine to the action of a revolving cutter with spiral or longitudinal
blades, or to a revolving brush, or to both, or to other equivalent instruments,.
for the purpose of removing the knots and impurities adhering to the paper,.
or the revolving cutter may be used for dressing paper.
Another part of my Invention is applicable to the paper making machine,.

or restoring the paper when broken at the edges in passing from the couch
roll to the felt, or from the first to the second press rolls, or from the second
press rolls to the drying cylinders; or to any intermediate rolls between the
drying cylinders.
In performing my Invention, a sponge or other equivalent is connected to a
lever and spindle, and the lever is made to press against the roll from which
the paper is passing. When a break takes place, the paper accumulates
between the lever and the roll, thus displacing the end of the lever and bringing
the sponge or other equivalent against the roll on the sheet and beyond the
break, the sponge is then drawn outwards to the edge of the sheet of paper
to prevent the break extending.
My improvements in the manufacture of paper cloth are particularly appli-
cable to the paper cloth described in the Provisional Specification of Letters
Patent, applied for by me on the 21st day of September, 1864, No. 2311,
but it may be applied to paper cloth of other descriptions, and to woven
fabrics; this part of my Invention consists in combining paper pulp or fibres
of cotton or other materials with the ordinary size, stiffening, or filling, which
may be employed in sizing, stiffening, and finishing woven fabrics, and applying
the same to paper cloth or woven fabrics by passing them through an ordinary
stiffening mangle or other suitable machine, the paper cloth or woven fabric
may be thus operated upon on one or both surfaces at one or more times.
