and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
the Invention communicated to me by a certain Foreigner residing abroad, of
"THE TRICOTEUR OR KNITTING MACHINE;" in which said Letters Patent there
is contained a proviso that if I, the said Marc Isambard Brunel, shall not.
particularly describe and ascertain the nature of the said Invention, and in
what manner the same is to be performed, by an instrument in writing under

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Marc Isambard Brunel, do hereby declare that the nature of the said Invention,
and manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawings hereunto annexed, and the following
description thereof, that is to say:-
The tricoteur or knitting machine is composed of the following parts, repre-
sented at full size in the Figs. 1 and 2:-A, A, A, Figs. 1 and 2, represent
a circular frame or wheel, which is suspended and fixed to a spindle B,
Fig. 2.
On the external rim of this frame or wheel the needles C, C, C, C,
are placed in a concentric direction all round the said rim.
Part only are
represented here. These needles are similar at their ends to those used in the
common stocking weaving loom. Their size and distance from each other are
regulated by the quantity of the work the machine is destined to. D, D, D,
Fig. 1 and 2, represent a wheel moving on the spindle B. This wheel is
intended to carry the arms E 1, E 2, E 3, and E 4, Fig. 1, one of which arms
(that marked E 3) is seen in Fig. 2. These arms carry the wheels that
from the knitting, and also the thread. The circular movement of this
wheel D, D, D, is intended to carry the four arins E, E, E, E, and the
bobbin F round the fixed frame A, A, A, on which the needles aré
fixed. The first arm E 1 carries a small wheel viewed in part in Fig. 4.
This wheel presses, by means of its pallets, the thread down between the
needle, and carries the samé thread under the hooks, and by its oblique move-
ment pushes it to the extremity of the hooks as seen at a, a, Fig. 1: The
second arm E 2 carries a small wheel, with long teeth-like radii, see
Fig. 3. The solid part G of this wheel bears on the hooks of the needles,
and presses their points down into the corresponding grooves. The radii of
this. wheel take the knitting or web already formed, b, b, Fig. 1, and slide
each stitch over the hooks of the needles. The next arm E 3, Figs. 1 and 2,
carries a wheel formed as represented in both Figs. 1 and 2. This wheel is
intended to throw the stitch completely over the extremity of the hooks. The
fourth arm E 4 carries a wheel nearly similar to that belonging to the arm E 2.
This wheel is intended to bring in the row of stitches just formed clear of
the hooks, as seen at 'd, 'd, d, Fig. 1. Several sets of these wheels, with the
bobbin, might be fixed round the wheel D.
The diameter and dimensions of this tricotteur or knitting machine is not
confined to 'the scale of that which is represented here. It may be smaller,
or may be extended to such a diameter as to be capable of knitting a web
equal in size to the largest carpets. The circular frame D, D, D, may be
stationary, in which case the circular frame A, A, A, is to move on the
