We GEORGE FREDERICK BUSBRIDGE of East Malling Mills East Malling in the
County of Kent Paper Manufacturer and JOHN HENRY TURVEY of East Malling
aforesaid Engineer do hereby declare the nature of this Invention to be as
follows:-
The object of this Invention is to provide a machine simple in construction and
efficient in action which will cut the rags or the like more efficiently than will
machines for the purpose as hitherto constructed.
According to this Invention we provide a trough into which the rags are fed and
they are drawn along by a pair of rollers preferably of a hexagonal figure and
delivered between two knives forming cutters acting as shears. These knives
should not be in one straight line across the machine but should extend in a
direction lengthwise as well as transversely so as to cut the rags simultaneously in
both directions in square or other shapes. We prefer for this purpose knives
shaped liked the teeth of a saw the projections of one passing between the
projections of the other and the one being angled or inclined with respect to the
other so as to commence cutting from one end or point. This gives the shearing
action referred to. The one knife is fixed horizontally at the end of the trough
and the other is moved vertically. This may be effected by an overhead crank
shaft and connecting rod attached to the knife which slides in vertical guides in
the framing. The feed rollers may be driven intermittently in the proper direction
by a pawl actuated from the same crank shaft and the delivering speed of the
rollers may be regulated by altering the throw of the pawl.

Agent for the said G. F. Busbridge

We GEORGE FREDERICK BUSBRIDGE of East Malling Mills East Malling in the
County of Kent Paper Manufacturer and JOHN HENRY TURVEY of East Malling
aforesaid Engineer 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:―
The object of this Invention is to provide a machine simple in construction and
efficient in action which will cut the rags, or other material (such for example as
rope) more efficiently than will machines for the purpose as hitherto constructed.
We will describe the Invention with reference to the accompanying drawings.
Figure 1 of which is a sectional elevation and Figure 2 a sectional plan of a
machine constructed according to this Invention Figure 3 is a perspective view
of the knives separately. We provide a trough A into which the rags or other
materials to be cut are fed which may be effected by a strap or moving apron B on
which the rags or other materials are placed or the feeding may be effected by
hand if desired. The apron B is moved or drawn along by being passed round a
revolving roller C the said roller being the bottom one of a pair of rollers C C
between which the rags or other materials pass. The periphery of the upper
roller is hexagonal or otherwise formed with a number of sides or it may be
fluted or grooved longitudinally as shown to assist the travelling and delivery of
the rags or other materials to between two knives D D' acting as shears. These
knives should not be in one straight line across the machine but should extend in
a direction lengthwise as well as transversely so as to cut the material simul-
taneously in both directions in square or other shapes. We prefer for this purpose
knives shaped like the teeth of a saw as shewn in Figure 3 the projections of one
passing closely through the spaces between the projections of the other, and the
relative positions of the knives being preferably angled, or inclined with respect to
each other, so that the cutting may commenco from one end or point. This gives
the shearing action referred to. The one knife D is fixed horizontally at the end
of the trough A and the other D' is moved vertically or otherwise. This may be
effected by an overhead crank shaft E and connecting rod (or rods) F attached to
this knife carrier G to which the moveable knife is fixed. This carrier G slides
in vertical guides formed in the framing H or the moving knife can be attached to
a revolving roll or cylinder as shewn in Figure 3 so that the teeth of the knives
thereon pass the teeth of the fixed knife during the revolution of the said roll or
cylinder which can take place.continuously or intermittently.
The feed rollers C. C may be driven intermittently in the proper direction by a
pawl I and ratchet wheel I' actuated from the same crank shaft E and the delivery
speed of the rollers to vary the length of the material when cut may be regulated
by altering the throw of the pawl. As the materials are cut in thick layers or
cakes they may be separated and opened out by falling into a distributor formed
by a rapidly revolving roller K. on the periphery of which are projections k and
this roller may throw the material forward to any required receptacle.
Although the drawing shews two knives it will be evident that a double set or
more of them may be employed if necessary.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is
First. The arrangement and combination of parts constituting the machine
for cutting rags or other materials substantially as herein before described and
illustrated in the accompanying drawings.
Second. In and for machines for cutting rags and other materials knives or
cutters which act as shears and do not extend in a straight line across the machine
but are in the form of the teeth of a saw or otherwise extend both lengthwise and
transversely of the direction of feed of the rags or other materials substantially as
and for the purpose herein before described.
Third. In machines for cutting rags or other materials knives or cutters acting
as shears and formed as claimed by the preceding claiming clause in combination
with means for operating them and for feeding the rags or other materials
thereto substantially as herein before described and illustrated in the accompanying
drawings.
