cocoa "mats in
Year: 1888

page_text: I JOHN DAVIDSON of Pine Street Mount Holly in the County of Burlington and
State of New Jersey United States of America Weaver 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:-
"
cocoa "mats in
My Invention relates to that class of rugs or mats known as
which a centre portion having tufts of coarse cocoa fibre is combined with a patterned
border of wool or other material finer than the centre the object of my invention being
to provide a border having a pattern of as elaborate a character as may be desired
without unduly increasing the cost of weaving the rug or mat.
This object 1 attain in the manner hereinafter set forth reference being had to the
accompanying drawings in which :—
Figure 1 is a view of a rug or mat made in accordance with my invention.
Figure 2 is an exaggerated diagram illustrating the mode of weaving a mat in
accordance with my invention.
Figure 3 is a longitudinal section through the border portion of the mat and
Figure 4 is a like section through the centre or cocoa portion of the mat.
Ordinary rugs or mats of the character to which my invention relates have a centre
portion of coarse cocoa fibre formed into tufts confined to the threads of the warp
and a border of wool or other finer thread which is likewise tufted the border being
ordinarily made by the process known as fingering' "that is to say strands of each
color required by the pattern being picked up from below the warp by the fingers at
"

page_text: the proper points so as to be looped around the warp and these loops being afterwards
cut at the top so as to form tufts confined by the warp threads. This as will be
evident is a tedious process which precludes the use of any considerable number of
colors in the border or the formation of any but patterns, of the simplest character.
In order to overcome this objection therefore 1 make the border A of the rug with a
chenille weft a the threads of which are colored to correspond with the desired pattern
to be produced this chenille thread being bound by fine warps which are tied down
by weft threads & shot across the shed from side to side although the chenille wefts
are only introduced in those portions of the shed which correspond with the borders
of the rug or mat that is to say, they extend completely across the shed at the opposite
ends of the mat to form the end borders but between those portions are confined to a
limited area at the outer edges of the warp corresponding in width to the width of
the side borders of the mat (See Figure 2) Two or more of these chenille wefts are
introduced into each side border for every row of tufts of coarse cocoa fibre in the
centre B of the mat the latter being bound by warps g of a coarser character than
those employed for binding the chenille threads of the border. The coarse warps
however extend from edge to edge of the mat and with the thick wefts d form the
back of said mat the spreading of the tufts of coarse fibre in the centre of the mat
and of the chenille threads in the border being sufficient to cover and hide the thick
weft and warp threads of the backing (See Figures 3 and 4).
The tufting of the cocoa threads in the centre portion of the mat is effected in the
usual way by passing the bunch of strands alternately under a raised warp of the
shed and over a slotted bar above the same and afterwards cutting the loops by a
knife passed through the slot of the bar this forming no part of my invention.
It will be evident that by forming the border upon the mat in accordance with my
invention patterns of a very elaborate character and having a great number of colors
can be produced with great facility so that a mat of a much more acceptable character
than those now made can be produced with but little if any increase in the cost of
the same.
Having thus described my Invention what I claim and desire to secure by Letters
Patent is
A rug or mat having a centre portion with tufts of cocoa or other coarse fibre and
a border with chenille wefts a series of which are employed for each row of tufts in
the central portion of the mat all substantially as specified.
