IMPROVEMENTS IN THE MANUFACTURE OF PILED VELVET AND THE LIKE
Year: 1880

page_text: LETTERS PATENT to Joshua Perkins, the younger, of Coventry, in the
County of Warwick, and of Imperial Chambers, Albert Street, Derby, in
the County of Derby, Trimming Manufacturer, for an Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF PILED VELVET AND THE LIKE."
PROVISIONAL SPECIFICATION left by the said Joshua Perkins Jr. at the
Office of the Commissioners of Patents on the 24th December 1880.
JOSHUA PERKINS, the younger, of Coventry, in the County of Warwick, and
of Imperial Chambers, Albert Street, Derby, in the County of Derby, Trimming
Manufacturer. "IMPROVEMENTS IN THE MANUFACTURE OF PILED VELVET AND
THE LIKE."
This Invention has for its object the manufacture of piled velvet and the like,
and has reference more particularly to the production of a velvet in which the
pattern is woven into the fabric at the time of weaving it, and in which a smooth
and even surface is secured.
In carrying it out, we accomplish these results by arranging the tappits acting
upon the healds and the jacquard machine to operate in the following manner :-
First. The jacquard machine raises the figure or pile with the half of the ground
warp and remainder of figure heald up, and the weft is inserted here with the
cutting wire in the ordinary way. The other part of the ground warp is then
raised, also a third warp, and a pattern or binder shoot or weft inserted which
raises the cutting wire, ensuring the latter coming perpendicular, so as to cut in
the centre of the pile, thus producing a smooth instead of a ribbed surface. This
arrangement applies to any design introduced or woven into the fabric or any
number of colors. It will be seen that the binding pick is woven with three ends
of the foundation warps up and one down, which raises the wire and keeps it in
a perpendicular position which constitutes the improvement.

by the said Joshua Perkins, J., in the Great Seal Patent Office on the

JOSHUA PERKINS, the younger, of Coventry, in the County of Warwick, and
of Imperial Chambers, Albert Street, Derby, in the County of Derby, Trimming
Manufacturer. « "IMPROVEMENTS IN THE MANUFACTURE OF PILED VELVET AND
THE LIKE."
This Invention has for its object the manufacture of piled velvet and the like,
and has reference more particularly to the production of a velvet in which the
pattern is woven into the fabric at the time of weaving it, and in which a smooth
and even surface is secured.
In carrying it out I accomplish these results by arranging the tappits acting
upon the healds and the jacquard to operate in the following manner :-
First. The jacquard machine raises the figure or pile with the half of the ground
warp, and the remainder of figure heald up, and the weft is inserted here with the
cutting wire in the ordinary way.
This part of the ground warp is still kept up; also a third warp is raised, and a
pattern or binder-shoot or weft inserted, which raises the cutting wire, ensuring
the latter coming perpendicular, so as to cut in the centre of the pile, thus
producing a smooth instead of a ribbed surface.
This arrangement applies to any design introduced or woven into the fabric of
silk, worsted, mohair, cotton, or other material used in the manufacture of velvet,
or any number of colours.
It will be seen that the binding pick or shoot is woven with three ends of the
foundation warps up and one down, which raises the wire and keeps it in a
perpendicular position to cut the loop evenly, which constitutes the improvement.
And in order that my Invention may be more clearly understood, I will now
proceed to describe the same by reference to the accompanying Drawings, in which
Fig. 1 is a weaver's draft according to my Invention, a, a, representing the
healds acting on the foundation warps; b, b, the healds raised for the warp; c, c, the
jacquard healds.
Fig. 2 is an enlarged vertical sectional view; d, d, shewing the pile; e, e, the
wool woven in the foundation; f, f, the weft; g, g, the foundation warps.
It will be apparent to any practical weaver that velvet made under my process
is closer, tighter, and better woven than that at present made, and the pile rendered
not so liable to pull or rub out, giving greatly increased wear.
Having now particularly described the nature of my said Invention, and in
what manner the same is to be performed, I would have it understood that what
I claim as my Invention is,-
Firstly. In the manufacture of piled velvet and the like, weaving in the binding
pick or shoot with three ends of the foundation warps up and one down, so that
the wire is raised, causing it to be kept. perpendicular, to cut the loop evenly, and
thus produce a smooth and even surface, substantially as described.
Secondly. The improved draft or method of weaving piled velvet and the like,
substantially as and for the purposes described.
In witness whereof, I, the said Joshua Perkins, the younger, have hereunto
set my hand and seal, this Twenty second day of June, in the year of
Our Lord 1001
JOSHUA PERKINS, JUNR. (L.S.)
