page_text: LETTERS PATENT to Edward Crossley, Carpet Manufacturer, of Halifax, in
the county of York and Richard Cochrane, Manager of the Weaving
Department also of Halifax, in the aforesaid county for an Invention of
"IMPROVEMENTS IN WEAVING CARPETS AND OTHER PILE FABRICS AND IN
APPARATUS CONNECTED THEREWITH"
PROVISIONAL SPECIFICATION left by the said Edward Crossley and
Richard Cochrane at the Office of the Commissioners of Patents on the
2nd May 1883.
EDWARD CROSSLEY, carpet manufacturer of Halifax in the County of York and
RICHARD COCHRANE, manager of the weaving department also of Halifax in the
aforesaid County IMPROVEMENTS IN WEAVING CARPETS AND OTHER PILE FABRICS
AND IN APPARATUS CONNECTED THEREWITH,'
"
Our said invention and improvements consist in cutting the pile of Carpets and
other pile fabrics of different lengths by means of deep wires having knives or
cutting blades or edges at the side, also in forming the wires with guides to hold
the pile warp fast until it has been cut by the knife or cutting edge or blade and
also to allow the insertion and withdrawal of the wires without injury to the
cutting edges,
For this purpose we employ by preference flat deep wires made of steel or other
metal having inclined knives or cutting blades or edges which are either cut out of
the steel or other metal or brazed on thin strips or bars left at one extremity of
the wires. The bars or strips holding the knives or blades or cutting edges are by
preference near the bottom part of the wire and the strip or bar carrying the
blade or cutting edge is slightly bent up at the end. The upper extremity of the
wire also terminates in a narrow strip or bar which projects beyond the blades
and inay be bent downwards so as to rest on the bent up extremity of the lower
strip or bar, in which case either one or both of the strips or bars must be

out to pass between them without, injury, resuming their original position after
the
passage of the blade. The bar at the top of the wire forms a guide to hold
the pile warp fast until it has been cut by the blade and the guide ensures the
uniform cutting of the pile of two different lengths or depths.
The angle or inclination given to the knives causes them to overlap one another
and the shape and pliability of the bars or strips allow the wires to be inserted
and drawn out without injury to the cutting edges of the same,
According to our method we can use any required number of our improved
wires without the addition of any ordinary pile wires.
We can employ wires having the top and bottom strips or bars not touching one
another but with a sufficient space between them to allow the blades to pass
without the necessity of making either of them act as springs.

Our invention and improvements consist in cutting the pile of carpets and other
pile fabrics of different lengths by means of deep wires having knives or cutting
blades or edges at the side; also in forming the wires with guides to hold the pile
warp fast until it has been cut by the knife or cutting edge or blade and also to
allow the insertion and withdrawal of the wires without injury to the cutting
edges.
For this purpose we employ by preference-flat deep wires made of steel or other
metal having inclined knives or cutting blades or edges which are either cut out of
the steel or other metal or brazed or otherwise attached to strips or bars left at one
extremity of the wires. The bars or strips holding the knives or blades or cutting
edges are by preference near the bottom part of the wire and the strip or bar
carrying the blade or cutting edge is slightly bent up at the end.
The upper extremity of the wire also terminates in a narrow strip or bar which
projects beyond the blades and may be bent downwards so as to rest on the bent.
up extremity of the lower strip or bar in which case either one or both of the
strips or bars must be sufficiently pliable to spring and allow the blades of the
wires whilst being drawn out to pass between them without injury, resuming their
original position after the passage of the blade. The bar at the top of the wire
forms a guide to hold the pile warps fast until it has been cut by the blade and
the guide ensures the uniform cutting of the pile of two different lengths or
depths.
The angle or inclination given to the knives causes them to overlap one another
and the shape and pliability of the bars or strips allow the wires to be inserted and
drawn out without injury to the cutting edges of the same.
According to our method we can use any required number of our improved
wires without the addition of any ordinary pile wires.
We sometimes employ wires having the top and bottom strips or bars not
touching one another but with a sufficient space between them to allow the blades
to pass without the necessity of making either of them act as springs
But in order to enable our improvements to be fully understood we will proceed
to more particularly describe the same by reference to the accompanying drawing
in which figure 1, represents a side elevation of our improved wire for cutting the
piles of carpets and other pile fabrics of different lengths, the wire is shewn cut in
two and drawn to an enlarged scale; figure 2, is a plan with top part cut away to
shew the knife or blade; figure 3, is a front sectional view of the same, and
figure 4, is a top view shewing the action of the blades when working with
two or more wires. Similar letters of reference in all the figures represent similar
parts.
A, represents flat deep wires made of steel or other metal having inclined knives
or cutting blades or edges B, which blades are either cut out of the steel or other
metal or brazed or otherwise attached to strips or bars C, which are slightly bent
up at the end at D. The upper extremity of each of the wires A, is made with a
narrow strip or bar E, having a curved extremity F, made with a bent up end G,

page_text: which rests or nearly rests on the top end D; both the ends D, and G, are made
slightly larger than the thickness of the strips or bars and are made flat on the
surface; the strips or bars C, and E, are made sufficiently pliable as to spring and
allow the blades B, whilst being drawn out to pass between the ends D, and G,
without injury and to allow them to resume their original position after the
passage of the blade through them. The bar E, forms a guide and holds the pile
warp fast until it has been cut by the blade, and the guide E, ensures the uniform
cutting of the pile of two different lengths or depths. The angle or inclination
given to the knives B, causes them to overlap one another and the shape and
pliability of the bars or strips allow the wires to be inserted and drawn out
without injury to the cutting edges H.
с
We can also use any number of our improved wires without the addition of any
ordinary pile wires; we sometiines employ wires having top and bottom strips or
bars not touching one another but with sufficient space between them to allow the
blades to pass without the necessity of making either of them act as springs.
Having thus described our invention and the best means we are acquainted with
for carrying the same into effect, we would have it understood, that what we
claim is
Firstly. The method or means of cutting the pile of carpets and other pile
fabrics of different lengths by the employment of deep wires having knives or
cutting blades or edges at the side, substantially as and for the purpose
herein before described.
Secondly. The construction and employment of deep wires having cutting blades
or, edges at the side and made with guides to hold the pile warp fast when weaving
pile carpets or other pile fabrics until the pile warp has been cut by the knife,
blade or cutting edge and allowing the insertion and withdrawal of the wires
without injury to the cutting edges; substantially as herein described and
represented in the accompanying drawing.
In witness whereof I the said Richard Cochrane for and on behalf of myself
and the said Edward Crossley have hereto set my hand and seal this twenty
ninth day of October in the year of our Lord one thousand eight hundred and
eighty three
