Improvements in and relating to Carpets and Upholstery Fabrics.
I, GOLDSBOROUGH SAPPINGTON GRIFFITH, Junior, residing at number 403 East
Baltimore Street, in the City and County of Baltimore, State of Maryland, one of the
United States of America, Merchant, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to carpet fabrics or fabrics for furniture covering, of the
character having a back of inferior material and a face of superior material, and the
object of the invention is to produce a solid back carpet or other fabric having good
wearing properties, and a smooth face, either adapted to receive designs by printing
or having the design produced therein by colored yarns.
The invention consists of a carpet or other fabric having a back formed of longi-
tudinal stuffing threads, pairs of binder warp threads, and weft threads, and a face of
weft threads united to the weft of the back by binder threads which alternately inter-
lock with back weft threads, as I will proceed now more particularly to set forth and
claim.
Referring to the accompanying Drawings:-
Figure 1, is a diagrammatic plan view of my fabric ;
Figure 2, is a longitudinal section, and-
Figure 3, is a transverse section.
The back has a stuffing composed of groups of four, more or less, strands or
threads, a, of jute or equivalent heavy and strong material, arranged parallel to the
warp, and laid parallel to one another, and extended from beam to beam, either
independently of the barnesses or through harnesses of their own, in the loom.
Between the successive groups is a pair of binder warp threads, b, of cotton or other
material, which threads are to be operated as usual by the usual harnesses of the loom ;
and co-operating with the binder warp threads, and on opposite sides of the stuffing,
are the weft threads, c, of cotton or linen. In order to make straight and strong
selvages, there is the outside pair of binder warp threads, 61, of cotton or other
material, and the straight longitudinal thread, d, bound in by the weft, c. The back
thus constructed is hard, solid and elastic in all directions. The face is composed, by
preference, of woollen weft threads, e, shot in single, or in pairs, to make a smooth
surface, and bound in by worsted warp threads, f, arranged in pairs and harness
operated, and these weft threads, e, are laid flat across the back, without loops, and
beaten up closely. The warps, f, alternately are engaged with the cotton wefts and
are crossed between each two pairs of woollen wefts.
It will be observed that the woollen weft, running at right angles to the stuffing,
cannot sink into it or between its constituent members, and hence a very hard and
solid carpet is produced, which will not permit dust to sift through. The face being
hard, flat and smooth will not "sprout" as does tapestry or body-Brussels, that is,
the face yarns will not catch and pull out, and will not catch and hold dirt; it may
be swept easily, and is susceptible of being easily and very perfectly printed. Made
up in solid colors, my carpet is particularly well adapted for halls, and for filling
ander and around rugs.
The selvage being straight, lengths of my carpet may be sewed together with
butting edges, as in the case of tapestry Brussels, and the like. The selvage pre-
erably contains also the two stuffing threads, a', arranged one above the other.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. An improvement in carpet fabrics or other fabrics, consisting of a back com-
posed of groups of four more or less, stuffing threads, laid straight, and parallel, and
running lengthwise of the warp, binder warp threads on each side of the groups of
stuffing threads, and weft threads interlocked with the warp threads and binding in
the groups of stuffing threads, and a flat face composed of weft threads crossing the
stuffing threads at right angles, binder warp threads interlocked with the weft
threads of the back and with the face weft threads, substantially as described.
2nd. A carpet fabric or other fabric having a back of straight parallel stuffing
threads,.binder warp threads and weft threads, a face of straight flat weft threads, and
binder warp threads interlocked with the weft of the back, and selvages baving part
of the back binder warps and a straight thread arranged outside thereof and bound
in by the back weft threads, substantially as described.
3rd. A carpet fabric or other fabric having a hack of inferior material consisting
of straight longitudinal stuffing threads of jute, arranged in groups of four threads
each, cotton or linen binder warps alternating with the groups of stuffing threads, and
a cotton or linen weft, and a face composed of woollen weft threads arranged in pairs
crosswise of the back, and flat thereon, and binder warps of worsted threads woven
with the woollen face weft and with the cotton or linen back weft, substantially as
described.
