IMPROVEMENTS IN CUTTER GUIDES FOR PILE FABRIC CUTTING MACHINES."
Year: 1877

page_text: LETTERS PATENT to Arthur Orrah, of Huddersfield, in the County of York,
Overlooker, for the Invention of "IMPROVEMENTS IN CUTTER GUIDES FOR
PILE FABRIC CUTTING MACHINES."
PROVISIONAL SPECIFICATION left by the said Arthur Orrah at the Office
of the Commissioners of Patents on the 13th September 1877.
ARTHUR ORRAH, of Huddersfield, in the County of York, Overlooker. " IMPROVE-
MENTS IN CUTTER GUIDES FOR PILE FABRIC CUTTING MACHINES."
This Invention relates to an improved construction of guide for the cutting
knives of machines for cutting looped fabrics.
According to this my Invention I construct the cutter or knife guide with
metallic (or other hard substance) ridgid sides, to which are attached, and projecting
beyond, steel pointers, which meet at their outer extremities, terminating in a
point; the latter enters the loop to be cut, and by reason of the elasticity of the
point of the guide and the tension upon the piece the point of the guide rises,
and is prevented piercing or puncturing the ground of piece, and the fineness and
evenness of the guides so made admits of full insertion of the guide, ensuring the
loop being cut along its true central line.

MENTS IN CUTTER GUIDES FOR PILE FABRIC CUTTING MACHINES."
"
IMPROVE-
This Invention relates to an improved construction of guide for the cutting
knives of machines for cutting looped or piled fabrics.
According to this my Invention I construct the cutter or knife guide with
metallic (or other hard substance) rigid sides, to which are attached steel or metallic
pointers which meet at their outer extremities, terminating in a point; the latter
enters the loop.or race to be cut, and by reason of the elasticity of the point of the
guide rises or falls with the cloth, and is therefore not as liable to pierce or puncture
the ground of piece, and the fineness or evenness of the guides so made admits of
full insertion of the guide, ensuring the loop or pile being cut along its true central
line.
Such being the nature and object of this my said Invention, I will proceed to
describe the same in detail; and in order that the same may be fully understood I
have hereunto annexed one Sheet of Drawings illustrative thereof.
According to this my Invention I construct the cutter or knife guide with
metallic (or other hard substance) rigid sides A and B (see Figs. 1, 2, and 3), to
which are attached the steel pointers C, D, which meet at their outer extremities
at E, terminating in a point E, the latter enters the loop or race to be cut, and by
reason of the elasticity of the point of the guide, and the tension upon the piece,
the point of the guide rises or falls with the cloth, and is prevented piercing or
puncturing the ground of piece, and the fineness and evenness of the guides so
made admits of a full or partial insertion of the guide, ensuring the loop or pile
being cut along its true central line. The attachment of the rigid sides I make
enables finer or smaller steel or metallic pointers to be used for insertion into the
races or loops to be cut, thereby enabling smaller ribbed pieces, with a larger
number of races or loops, to be cut at once.
In some cases I employ but one rigid side A, as at Figs. 4 and 5, and attach one
leg C of the guide thereto, so as to leave the entrance at F open.
At Fig. 6 the guide C is shewn attached to the rigid side near its other end, so
as not to project beyond the length of the rigid side or sides.
At Fig. 7 a part of the rigid sides are shewn as extending beyond their broader
or wider part.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be performed or carried into
practical effect, I would have it understood, that I do not claim per se the steel
pointers C, D; but what I do claim is the combination or employment of such
rigid supports A, B, or A, as at Figures 4 and 5, when attached to and used in
combination with the pointers C, D, for the purpose herein described and illus
trated.
In witness whereof, I, the said Arthur Orrab, have hereunto set my hand
and seal, this Eleventh day of March, in the year of our Lord One thousand
nicht hundred and saventy-eight
Witness,
