Ebenezer Pocock at the Office of the Commissioners of Patents, with
their Petition, on the 12th September 1866.
We, ENOCH HARRISON AYDON, of No. 3, Great Queen Street, Westminster,
in the County of Middlesex, Civil Engineer, and EBENEZER POCOCK, of
Clapham Square, in the County of Surrey, Gentleman, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR CUTTING
RAGS, ROPES, AND OTHER ARTICLES FOR PAPER MAKING AND OTHER PURPOSES," to
be as follows:-
This Invention has for its object improvements in machinery for cutting
rags, ropes, and other articles for paper making and other purposes, for which
we make use of a series of circular knives fixed upon and revolving with a
shaft and kept at any required distances apart by means of washers or distance
pieces placed between them and capable of being readily removed when it is
required to substitute others for them so as to change the distances between the
knives. Each knife is steadied at two or more points of its circumference
near to the part at which the cutting takes place, by means of blocks of wood,
metal, or other material between which it works, and which assist also in
maintaining its edge. The rags or other articles to be cut are introduced
into the machino by means of a hopper or sloping mouth, whereby they are

page_text: guided on to an endless web or belt between which and a revolving fluted or
roughened roller they are drawn onward to the knives and after passing
between them so as to be cut as required are discharged from the machine;
machines having circular knives as described may in some cases be formed
with duplicate hoppers and feeding arrangements, so that in the event of the
rags or other inaterial not being cut sufficiently small by passing between
the knives from the first hopper, it may be again by means of the second
bopper passed between a different part of the knives and thereby farther
divided. Otherwise instead of circular knives as described, band knives
actuated in a manner similar to that ordinarily employed for actuating band
saws and suitably guided and steadied by means of guide blocks may be used,
and the rags or other articles to be cut may be fed or supplied thereto in a
manner similar to that already described with reference to the circular knives.
In other cases instead of either circular or band knives as described we make
use of knives having a reciprocating motion imparted to them by means of
cranks or other equivalent means, and suitably guided and steadied (by means
of blocks or otherwise) at each side of the part at which the cutting takes
place. The material to be cut is presented to the action of the reciprocating
kuives by means of a hopper, belt, and roller as made use of where circular
or band knives are employed, the rags or other material being pressed forward
against the edges of the knives, and after being cut and passing between
them leaving the machine by the exit end or continuation of the hopper.
From the foregoing it will be observed that sawing machinery generally, if
knives be substituted for saws, and suitable arrangements as described be
provided for feeding or supplying the rags or other material to be cut is
applicable to the purposes of our Invention.
