IMPROVEMENTS IN THE MANUFACTURE OF SEATING CLOTH, FOR UPHOLSTERY PURPOSES, COMPOSED OF POLISHED YARNS
Year: 1885

page_text: I, GEORGE PRINCE LEE, of Longsight Manchester, Manufacturer, do hereby
declare the nature of my invention for "IMPROVEMENTS IN THE MANUFACTURE
OF SEATING CLOTH, FOR UPHOLSTERY PURPOSES, COMPOSED OF POLISHED YARNS,"
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The improvements relate to the manufacture of seating cloth which consists of a
woven fabric composed of polished yarns, and used for upholstery purposes, as is
well understood.
These fabrics have been, for the greater part, hitherto woven in plain cloth, or at
most in the form of a twill continuous in one direction; whereas the object of the
improvements is to produce on the surface of such fabrics a wavy appearance or
zig zag formation, by which means a new effect is obtained.
To accomplish my improvements, I employ, in conjunction with a suitable loom,
either a jaquard, dobby, or tappet motion, whereby I am enabled to actuate the
healds in the manner required for the production of the results named. I employ,
by preference, eight shafts in the case of dobby or tappet arrangement, or the same
number of warp threads to the tie-up in the case of jaquard arrangement, as giving
the most suitable effect for the present requirements of the trade; but a lesser or
greater number may be employed according to the width and length of the wave
form desired.
I actuate the healds in such manner that the warp threads are lifted so as to
form for a portion of the round of picks a floatation of the weft as an eight or
other shaft twill up to a certain point about midway in the round, when the other
portion is reversed in its action so as to form the twill effect in the contrary
direction for the remainder of the round. By which means a kind of twill in one
direction is woven on one portion of the cloth, and on the other portion the twill
formation traverses in the opposite direction, thus forming a wave or zig zag effect.
The number of threads in the tie-up, or the number of shafts of healds employed
may be varied, as also may the number of picks during which the two directions of
twill are continued, without departing from the peculiar character of the improve-
ments, and the like effect may be produced by means of floating the warp threads
in a similar manuer in lieu of the weft, by augmenting the number of shafts.

page_text: The diagram shews a draft of the action of the threads or shafts of healds for
an eight shaft or tie-up, and an eight motion twill basis, and also the reversal of
the twill formation as described. But other lengths of twill formation may bo
adopted.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The Manufacture of Seating Cloth for Upholstery purposes, composed of polished
yarns, by means of jaquard, dobby, or tappet motion, in such manner that the twill
of the cloth is formed in two contrary directions either by means of the weft or
warps being floated or brought to the surface, so as to produce a waved or zigzag
effect thereon, whether of larger or smaller wave, or longer or shorter twill, or
both, substantially as shewn and described.
