PROVISIONAL SPECIFICATION.
Improved Cord or Pile Fabric.
JOHN GREY, Church View. Norden, Rochdale Lancashire Salesman and
WILLIAM TAYLOR, Church View Norden Rochdale Lancashire Manager do
hereby declare the nature of this invention to be as follows:-
Our invention consists in an improved method of manufacturing light 8-shaft
cords whereby an improved back retaining an even and full pile is made. The
objectionable way of robbing the pile to fill up the back is entirely removed.
In performing our invention we employ a loom of ordinary construction in which
tappets of 9 to the round are used.
The weft is floated over the warp for producing races, which when cut form the
face of the cord and the back or ground picks are thrown in after the requisite
number of floating picks have been introduced, but in order to produce a fuller pile
and to avoid robbing the pile to fill the back which is customary in light cords, we
apply our new back consisting of a 3-end twill instead of 4-end twill as is usual,
thus accomplishing a long desired result.
The above improvement may be used in making Genca cords.

SPECIFICATION.
Improved Cord or Pile Fabric.
JOHN GREY, Church View Norden Rochdale Lancashire Salesman WILLIAM
TAYLOR, Church View Norden Rochdale Lancashire Manager, 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:-
Our invention consists in an improved method of manufacturing light 8-shaft
cords whereby an improved back retaining an even and full pile is made. The
objectionable way of robbing the pile to fill the back is entirely removed.
In performing our invention we employ a loom of ordinary construction in which
tappits of 9 to the round are used. The weft is floated over the warp for producing
races which when cut form the face of pile of the cord, and the back or ground
picks are thrown in after the requisite number of floating picks have been
introduced.
In making 8-shaft cords it is customary to put two face or pile picks between
each back or ground pick, but in making light weights, it is usual to put one
pile pick between the first two ground picks and then two pile picks between
the next two ground picks, and so on alternately until the pattern is complete.
This is necessary in order to bind the pile in a light weight cord and to shew
a finer twill on the back. Thus robbing the pile of one pick between every
alternate ground pick.
In our invention the face or pile is not robbed at all, as the ground or back is
composed of a three end twill, which enables us to put two pile picks, between each
two ground picks, see Figures 1 and 2.
Figure 1 shews design of cloth, with the twill on the back of the cloth, running
to the left hand. Numbers 1 to 12 represent the warp threads, and numbers 1 to 9
represent the weft picks, The crosses in the squares represent the warp threads

page_text: raised above the weft picks, and the blank spaces represent the weft picks floating
over the warp threads.
Figure 2 is the same design, but with the twill on the back of the cloth running
to the right hand.
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 greatly improved light 8-shaft cord with a finer back and fuller pile.
Dated this 16th day of November 1892.
