A YARN DRYING MACHINE
Year: 1852

page_text: LETTERS PATENT to Bowman Fleming McCallum, of Govan Croft
Dye Works, Glasgow, in the County of Lanark, Dyer, for the
Invention of "A YARN DRYING MACHINE."
Sealed the 22nd February 1858, and dated the 30th October 1852.
PROVISIONAL SPECIFICATION left by the said Bowman Fleming
McCallum at the Office of the Commissioners of Patents, with
his Petition, on the 80th October 1852.
I, BOWMAN FLEMING MCCALLUM, do hereby declare the nature of the
said Invention for "A YARN DRYING MACHINE" to be as follows:-
A machine consisting of a number of reels or spindles revolving by
motive power, in a chamber heated by fire, steam, or otherwise; the
yarn passes over and round the reels, either horizontally or perpendicu-
larly, and from the construction of the reels there is little friction, and
at same time a motion given, by means of which the yarns are dried &
stretched in a manner not hitherto accomplished.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Bowman Fleming McCallum in the Great Scal
Patent Office on the 16th March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
BOWMAN FLEMING MCCALLUM, of Govan Croft Dye Work, Glasgow,
in the County of Lanark, Dyer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of October, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Bowman Fleming McCallum, Her special licence that
I, the said Bowman Fleming McCallum, my executors, administrators,
and assigns, or such others as I, the said Bowman Fleming McCallum,
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 "A YARN DRYING
MACHINE," upon the condition (amongst others) that I, the said Bowman
Fleming McCallum, by an instrument 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 Bowman Fleming McCallum, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked
thereon (that is to say):
My Invention relates to an improved mode of drying yarn, whether
colored or uncolored, and whether composed or made of cotton,. silk,
wool, flax, or any other material, by passing the yarn by machinery over

page_text: and under a series of reels, having a circular and lateral motion com-
bined, through an apartment in which the atmosphere is heated by
artificial means to any desired temperature, and in such a manner that
the yarn is dried without injury to the coloring or fabric, and the
threads are kept more straight and better separated from each other
than by any other method hitherto known.
And in order that the Invention may be more fully understood and
carried into effect, I will proceed to describe the Drawings hereunto
annexed.
Figure 1, represents a top view of my yarn drying machine.
Figure 2, represents a lateral view of the same. A, the yarn, in a
wet state, passing into the machine over the rollers marked a, and
carried along to the other side, when it passes back again over the reels
marked c, until at d, it passes back again along the top rollers until it
comes to e, where it passes as formerly over the reels, and so on, as often
as is shewn in Figure 1, and when dry is made to pass out of the hot
chamber at B, and over the roller F, and is deposited in a dry state E.
D, D, D, is sides and roof of the chamber in which the machine is con-
tained, and is heated by means of "Hazards Patent," or any other
method capable of producing a strongly heated atmosphere constantly
renewing.
The motion, as communicated from the engine to the reels, is by belt
and pulley, as shewn in Figure I, and then by bevel gearing with all
the top reels, the lower ones being moved by the yarn passing round
them; the roller marked F, (Fig. I.) at the front of the machine
(being also driven by same means, takes off the dried yarn as quickly
as it is taken in.
I would remark that, although I have shewn the exact particulars of
construction of every part, I do not confine myself thereto, so long as
the peculiar character of a series of reels and machinery having a
lateral and circular motion combined, in a chamber containing an
atmosphere artificially heated, over, by, and through which the yarn is
carried during the process of drying; and that what I claim as my
Invention is, the passing yarn, for the purpose of drying the same,
through an artificially heated atmosphere, by means of machinery

page_text: having a combined circular and lateral motion, by which the yarn is
dried without injury to the color or substance of the same, and the
threads are prevented from being entangled with or adhering to each
other. And that I disclaim any intention to include as part of my said
Invention any mode or means for heating the atmosphere of the
apartment or chamber in which the machinery is contained.
In witness whereof, I, the said Bowman Fleming M.Callum, have
hereunto set my hand and seal, this Twelfth day of March, in
the year of our Lord One thousand eight hundred and fifty-three,
at Hamilton, County of Lanark.

Fleming McCallum in the presence of

Peace for Lanarkshire.
