IMPROVEMENTS IN DRYING YARNS
Year: 1853

page_text: LETTERS PATENT to Marcel Vetillart, of Le Mans, France, for the
Invention of IMPROVEMENTS IN DRYING YARNS."
Sealed the 27th August 1853, and dated the 2d March 1853.
PROVISIONAL SPECIFICATION left by the said Marcel Vetillart at
the Office of the Commissioners of Patents, with his Petition, on
the 2d March 1853.
I, MARCEL VETILLART, of Le Mans, France, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN DRYING YARNS" to
be as follows:-
My improved drying apparatus consists of a box or chamber, from
end to end of which a current of heated air is constantly caused to pass,
either by forcing it in at one end, or by drawing out the air at the other.
Into this box the yarns to be dried are inserted on a frame, in such a
manner that the frame last put in is nearest to the end of the box or
chamber at which the air escapes, each frame being caused to move in
succession towards the end of the box where the hot air enters. By this
arrangement, as the yarns travel forward and become more and more
dry, they are met by air which is both hotter and dryer than that by

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Marcel Vetillart, in the Great Seal Patent Office,
on the 2d September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
MARCEL VETILLART, of Le Mans, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of March, in the year of our
Lord One thousand eight hundred and fifty-three, in the sixteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Marcel Vetillart, Her special licence that I, the said
Marcel Vetillart, my executors, administrators, and assigns, or such
others as I, the said Marcel Vetillart, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN DRYING YARNS," upon the
condition (amongst others) that I, the said Marcel Vetillart, by an in-
strument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Marcel Vetillart, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof (that is to say):
My improved drying apparatus consists of a box or chamber, from
end to end of which a current of heated air is constantly caused to pass,
either by forcing it in at one end, or by drawing out the air at the other.
Into this box the yarns to be dried are inserted on a frame, in such a

page_text: manner that the frame last put in is nearest to the end of the box or
chamber at which the air escapes, each frame being caused to move in
succession towards the end of the box where the hot air enters. By this
arrangement, as the yarns travel forwards, and become more and more
dry, they are met by air which is both hotter and dryer than that by
which they have been previously acted upon, and the drying will thus
be greatly facilitated. And in order that my Invention may be most
fully understood and readily carried into effect I will proceed to describe
the drawing hereunto annexed.
Figure 1, shews a side elevation, partly in section, of a machine
arranged according to my Invention; and Figure 2, shows a section of
the machine taken at the line X, X, of Figure 1; and Figure 3, is a
plan of one of the frames on which the yarn is placed. A, A, is a
chamber constructed of well-seasoned wood: the bottom B, of the
chamber is open to allow the passage of a current of air, which follows
the direction of the arrow, and escapes at the opening at C, at the top
of the chamber. D, D, are moveable frames, which are each furnished
with four wheels or castors r, r: these frames are placed one on the
other in the chamber. To draw out the lowest frame all the other
frames are held up by means of the four arms J, J, which are furnished
with friction pulleys i, i, which come against the under part of the
lowest frame but one, and thus relieve the lowest frame from the weight
of those above, and allow it to be easily withdrawn on the rails E, by
the opening E, after raising the door G. The dry yarn is then removed,
and the frame is again charged with wet yarn. To reintroduce this
frame all the frames which are in the chamber are caused to descend,
which is done by pushing down the lever L, which is outside of the
chamber. This lever is fixed on an axis a, which also carries the two
arms J, J, which are connected to the two back arms J, J, by the
rods k, so as to cause the four arms to move all together to lower the
frames gradually and evenly. When the arms have arrived at their lowest
position, as shown in dotted lines in Figure 1, the lever L, is again
raised to its first position, when the friction pulleys i, i, pass the lowest
frame by the notches o, o, (Figures I. and III.) in the sides of the
frame. The frame, which has been recharged, is then placed on the

page_text: upper rails i, the door P, is opened, and the frame is introduced by the
opening F. b, b, (Figure III.) show the rods between which the yarn
is extended.
Having thus described the nature of my Invention, and the manner
of performning the same, I would have it understood that I do not
confine myself to the precise details described, which may be varied to
a considerable extent without departing from my Invention; but what
I claim is the mode herein described of arranging apparatus for drying
yarns, whereby the yarns, placed on frames D, D, are subjected to the
action of a current of air in such a manner that the air when it enters
hot and dry acts first on the yarns which are nearest dry, and then, in
succession (as the air becomes cooler and damper), on yarns less and less
dry.
In witness whereof, I, the said Marcel Vetillart, have hereunto
set my hand and seal, this Twenty-fourth day of August, in the
year of our Lord One thousand eight hundred and fifty-three.
MARCEL VETILLART. (L.S.)
Witness, P. JANSON, of No. 20, Cornhill, Stationer.
