Complete Specification Left, 28th Aug., 1893-Accepted, 30th Sept., 1893
PROVISIONAL SPECIFICATION.
Improvements in Wires used in the Manufacture of Woven Cut
Pile Fabrics.
We, JAMES EDWARD STONE, and FRANK STONE both of Kidderminster in the
County of Worcester, Manufacturers, do hereby declare the nature of this invention
to be as follows :-
Wires used in the manufacture of cut pile fabrics are commonly made flattened
at one end and sharpened to form a sharp cutting edge for cutting the pile when
the wire is drawn out endwise from pile loops which have been formed around it.
According to our invention we form the wires with a slot in them along the end
portion and insert into this slot the back of a sharp cutting blade.
We also bend
over the extremity of the slotted end of the wire to bring it to a curved hook form
to pass around and come above the end of the blade so as to hold the blade
securely.
In this way the cutting blade may readily be removed when necessary and
another put in its place and in addition as the upper part of the curved hooked
end of the wire is blunt the warp threads are not liable in case of accident or
mishap to be cut in the loom as is the case with wires now in use.

COMPLETE SPECIFICATION.
Improvements in Wires used in the Manufacture of Woven Cut
Pile Fabrics.
We, JAMES EDWARD STONE, and FRANK STONE, both of Kidderminster in the
County of Worcester, Manufacturers, 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 :-
Wires used in the manufacture of cut pile fabrics are commonly made flattened
at one end and sharpened to form a sharp cutting edge for cutting the pile when
the wire is drawn out endwise from pile loops which have been formed over it.
According to our invention we form the wires with a slot in them along the end
portion and insert into this slot the back of a sharp cutting blade. We also bend
over the extremity of the slotted end of the wire to bring it to a curved hook form
to pass around and come above the end of the blade so as to hold the blade
securely.
In this way the cutting blade may readily be removed when necessary and
another put in its place and in addition as the upper part of the curved hooked
end of the wire is blunt the warp threads are not liable in case of accident or
mishap to be cut in the loom as is the case with wires now in use.
Figure 1 of the drawing annexed is a side elevation of a pile wire constructed
according to our invention.
Figure 2 is a side elevation of the cutting blade.
Figure 3 is a cross section on the line a, b, Figure 1.
A groove A¹ is first formed along the upper edge of a wire A at the end which
is to carry the cutting blade-this end of the wire is then bent over into a hook
form'as shewn at Figure 1. The bend is slightly more than a semicircle so that
the extremity of the wire inclines slightly towards the straight unbent portion of

page_text: the wire. The cutting blade B which is of thin sheet steel is as shewn shaped in
such a way that the back edges which have not to be used as cutting edges fit into
the groove along a portion of the straight part and into the groove in the curved
over end. As the extremity of the curved over end is made to incline slightly
towards the straight portion of the wire this portion of the wire will be sprung
slightly outwards when the rear portion of the cutting blade is inserted into or
withdrawn from the groove A'-when the cutting blade has been pushed into its
place the curved over end will spring back and its extremity entering the small
notch B' will hold the blade securely. The edges of the blade which have to enter
the groove A' are bevilled or chamfered off so that they may enter the groove
readily.
In this way the blade can readily be removed whenever necessary and another
blade inserted instead of it.
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. A pile wire grooved at one end along its upper edge and bent over into a
hook form to form a holder for the back of a cutting blade substantially as
described.
2. A pile wire having its cutting end formed substantially as bereinbefore
described and illustrated in the drawing annexed.
