Improvements in the Manufacture of Rugs and Carpets.
I, GOTTFRIED HORNIO, Manufacturer, of Gnadenfrei, in the German Empire, 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:-
This invention relates to the manufacture of imitation Smyrna rugs and carpets,
and has for its object to effect a saving of wool, besides facilitating the manufacture.
For this purpose I dispense with the Smyrna knot and fix the Smyrna thread or
pile by sewing it to the ground fabric, as will be hereafter more fully described with
the aid of the accompanying drawings, in which Fig. 1 is a front view of a ground
fabric in the course of manufacture, which fabric may have any desired width;
Fig. 2 shews the position of the warp threads and weft threads in relation to the
carpet threads worked into the fabric, and Figs. 3 to 6 represent various methods of
securing the carpet threads to the warp and weft threads.
The warp threads a may be made of any textile material and may have any
desired colour. They are tied together by means of weft threads b, for which
purpose the warp threads are changed by hand or by any mechanism suitable to form
a shed.
To the groundwork produced in this manner are now applied and fixed the carpet
threads, (which have been cut to uniform short lengths) by laying each carpet thread
round one, two or more warp threads (Figs. 3 and 34) and then sewing them
to the latter, as shown by Figs. 3 to 6. The free ends of the carpet threads are
upright and form the surface of the carpet.
Instead of laying the carpet threads round the warp threads, cach carpet thread
may be placed between two adjoining warp or weft threads and attached in this
position by sewing, as indicated by Figs. 4, 44 and 4".
In Figs. 5 and 5^ the carpet threads are sewn on the weft threads b, instead of
being sewn together with the warp threads.
The important feature in all these modifications is the fact, that the pile or carpet
threads are not tied or attached by means of knots, but my sowing or by some
analogous process, and in so doing the carpet threads may even be sewn to the face
of the warp threads or weft threads (Fig. 6) instead of being tied or sewn into the
same, in which case the groundwork forms a base or protective cover for the carpet
threads sewn to its face; so that those parts of the carpet threads which immediately
adjoin the ground work will be protected from wear and tear.
For the inanufacture of the groundwork various kinds of looms may be employed.
The carpet threads may be fixed to the warp or weft threads by hand or
mechanically by sewing or analogous processes.
Instead of producing the groundwork at the same time as the pile fabric, a ready
made woven fabric (such as canvas or linen) may be used as a base for small
carpets, as illustrated by Figs. 7 and 8.
The carpet threads (Figs. 7 and 8) are firmly enclosed by the sewing threads a
and connected with the ground work consisting of a net or open mesh fabric, by
forming a single or multiple coil.
The process for the manufacture described abovo gives the advantage that the
carpets require considerably less wool, because the thread loops usually required
for the formation of knots in the ordinary process of making carpets are dispensed

page_text: with, and the length of thread is thereby considerably reduced, and in addition, tho
manufacture of carpets is more expeditious.
Having now particularly described and ascertained the naturo of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The process for the manufacture of imitation Smyrna carpets or rugs, which
consists in placing the suitably cut carpet threads or pile threads between or upon
the warp or weft threads, and fixing them by means of sewing threads, or by fixing
them on the surface of a ready made or simultaneously prepared groundwork by
means of sewing threads, substantially as described.
2. The process for the manufacture of imitation Smyrna carpets or rugs, which
consists in fixing the suitably cut carpet or pile threads upon a ready made net or
openwork fabric by means of sowing thread, substantially as described and illustrated
by Figs. 7 and 8.
Dated this 25th day of February 1896.
