PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting or Severing Cloth Specially
Woven for Dividing down the Centre and the like.
We, JOHN HOWARTH, "Mechanic," of 13 Australia Terrace, and WILLIAM THOMAS
HOWARD, "Blacksmith," of Longsight View, both in Tottington Road, Tottington,
near Bury, in the County of Lancashire, do hereby declare the nature of this inven-
tion to be as follows:-
.
Our Invention relates to an apparatus for cutting or severing cloth specially woven
for dividing down the centre, or any like position.
The invention consists of a curved knife attached to a horizontal bar, the said bar
working on a pivot at each end, and mounted in between two arms, or a semi-circle
on a perpendicular shaft. Each of the pivot pins consists of short bolts pointed at
the end and screwed into the ends of the two arins or semi-circle, to permit the bar to
swivel on the pivots, or to set the knife to any desired angle.
The cloth is woven where it is required to be cut without a twist, and being the
weakest portion, the knife is easy on its axis will follow the slit as the cloth
travels past the knife.

Improvements in Apparatus for Cutting or Severing Cloth Specially
Woven for Dividing down the Centre and the like.
We, JOHN HOWARTH, "Mechanic," of 13 Australia Terrace, and WILLIAM THOMAS
HOWARD, "Blacksmith," of Longsight View, both in Tottington Road, Tottington,
near Bury, in the County of Lancashire, do hereby declare the nature of this inven
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
Our invention relates to an apparatus for cutting or severing cloth specially woven
for dividing down the centre or any like position. And in order that our Invention
may be thoroughly understood, we now proceed to describe the accompanying draw-
ings thereof, reference being had to letters and figures marked thereon.
Figure 1 represents the plan of the top of the apparatus with the knife B, fixed to
a frame work D, and arms E, with all the joints working on pivots, or set screws A,
and bolted to a piece of timber C.
Figure 2 denotes the side view of the arm E.
Figure 3 is a side elevation of the apparatus, with parts keyed together at G, and a
tension swivel F at the top, which is pressed against the cloth to prevent it being slack
in places.
Figure 4 represents an enlarged section of the knife.
Figure 5 is an enlarged view of the tension swivel, for keeping each edge of cloth
equal tension after being cut.
The invention consists of a curved knife B attached to a horizontal bar, the said bar
working on a pivot at each end and mounted in between two arms, or a semi-circle B¹
on a horizontal or perpendicular shaft.
Each of the pivot pins A consists of short bolts pointed at the end and screwed
into the ends of the two arms or semi-circle B', to permit the bar to swivel on the
pivots A, or to set the knife to any desired angle.
The cloth is woven where it required to be cut without a twist, and being the

page_text: weakest portion of the fabric, the knife is easy on its axis will follow the slit and sever
the material as the cloth travels above and below a series of rails, past the knife and
on to rollers. The knife moving from a centre on a rigid bar stands twisted in the
slit, whereas by this Invention the knife is always at right angles to the cloth and
therefore not as liable to come out of the radius motion of the mechanism.
The tension swivel is arranged to prevent the cloth having slack places in it, the
said swivel being pressed down against the cloth if one edge offers to be loose, and by
this means is forced out equal to each other.
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
First The combination of the apparatus for cutting or severing cloth specially
woven for dividing down the centre or the like, substantially as herein described
and according to the accompanying drawings.
:
Secondly The combination of the apparatus to give a special form of motion, and
the joints connected with the knife working on pivots, and the special form and section
of the knife. substantially as herein described and according to the accompanying
drawings.
:
Thirdly The tension swivel F to regulate any slack places in the cloth under the
operation of cutting, and to keep both edges equal substantially as herein described
and according to the accompanying drawings.
