A communication from abroad by Henri Carron, of 2, Rue St. Jean,
Lyons, in the Empire of France.
J, ANTON CARRON, of 25, Little Moorfields, in the City of London, do hereby
declare the nature of the said Invention for "AN IMPROVED LOOM FOR THE
MANUFACTURE OF SILK AND OTHER VELVET," being a communication from Henri
Carron, of 2, Rue St. Jean, Lyons, in the Empire of France, to be as
follows:-
This Invention consists of a loom conducted with a weaver's beam; the
alternate motion imparted to it is soon changed into a circular one, and
transmitted to the various moveable pieces of which the apparatus is
made up.
The accompanying Drawings will illustrate the following description:-Tho
warping is to be rolled round the roller A, and passes between the rollers B
and C, which are almost entirely wrapped up by it. These two rollers are
surrounded by a flexible tissue, and in contact with each other, so that the silk
is not allowed to go astray. After leaving the roller B, the threads that make
up the warp of the stuff are separated, and pass through a frame G, the
opposite borders of which are smoothed by glass rods. An important improve-
ment lies in the very disposition of such pieces, calculated to keep a regular
distance between the two stuffs, and to give to every piece a very uniform.

rollers I and J, Figs. 1 and 2, joined together at each end by two cross bars,
is to be placed at the top of another similar frame; they must be kept in
immediate contact by small spindles and screws, so that they should be properly
drawn closer or put aside while they go through the above-named sashes; the
pieces are, moreover, reunited by the threads forming the nap. Every row is
shorn one by one. When the pieces are done, they are divided, and next rolled
around a series of rollers. Their adhesion to the stuff is owing to its tension.
The razor which cuts the nap and the shearing apparatus are the objects of a
peculiar improvement, for they reach the highest degree of perfection and
exactness in the trimming. The two rulers J, which are in close contact,
have a sloping cut in front, and in all their length betwixt may be inserted
the cutting blade, which is carried by a small waggon L sliding in both
grooves of a long ruler M, Figs. 1 and 2. An iron rod, which can be put or
taken away at will, leans slightly on the waggon to prevent the shearing appa-
ratus from going out of the way. The ruler M is terminated on cach side by
two rods engaging themselves into the cross bars N, N, and next into the
stoppers S, T. The cross bars N are to be lowered more or less by the means
of screws, in order to give the ruler a proper lever and direction; the nuts P
are used to hang up the ruler, and to maintain it in a chosen position. The
bar that separates the two stuffs is fastened by bolts, and when necessary can
be removed. At every clapping of the loom the waggon L is made to run
right and left, and to cut down a row of silk at a time; whenever it reaches
the end the blade is sharpened on whetstones S, S, placed by the side of the
pieces.
The double lists of the warp are set in motion by pedals, by the means of
an eccentric and the general motion. The same pedals alternately work upon
the nap lists. The silk threads destined to form the nap of velvet pieces are
rolled round a cylinder M; at the same time they wrap up two other rollers,
which are in close contact; the last one is set in motion by a regulator, which
gives up at every instant a quantity of silk just necessary to form the velvet.
Should the silk come too abundantly, the web might be too thin; it would be
quite the reverse in the case of the silk coming sparingly, for on account of the
overstraining of the threads the stuff would be made tighter, the height of
the nap would be lessened, and of course such a proceeding would interfere
with the nicety and regular making of the pieces.
On the upshot the following advantages will be obtained-1st, to regulate
at will the height of the nap, making up the velvet by drawing nearer the

page_text: rulers, by keeping them uniformly distant from each other, and by stretching
equally the pieces after the running of the looms; 2nd, to raise or lower the
blade of the razor by the means of screws, which allows to cause it to pass with
the greatest accuracy just at an equal distance from both webs; 3rd, to supply
continually and in a just measure the quantity of silk necessary to form the nap
of the velvet.
I reserve to myself the faculty to perfectionate this Invention, and to
applicate the different kinds of my improvements to other looms destinated to
make cotton or other stuffs.
