IMPROVED MACHINERY FORRAWING FIBROUS
Year: 1858

page_text: LETTERS PATENT to Eugène Morel, of the City of Ghent, in Belgium,
Administrator Director of the Société de la Lys, Flax Spinning
Company, in Ghent, for the Invention of "IMPROVED MACHINERY FOR
"
A communication
PROVISIONAL SPECIFICATION left by the said Eugène Morel at the
Office of the Commissioners of Patents, with his Petition, on the 6th
March 1858.
I, EUGÈNE MOREL, of the City of Ghent, in Belgium, Administrator Di-
rector of the Société de la Lys, Flax Spinning Company, in Ghent, do hereby
declare the nature of the said Invention for "IMPROVED MACHINERY FOR DRAWING
FIBROUS SUBSTANCES," to be as follows:-
This Invention relates to an improved mode of distributing the amount of
pressure put upon the upper and lower pressing rollers of spinning frames;
these rollers are mounted in pendent carriers, each carrier being fitted with
two bearings to receive the axles of the rollers. The upper bearing or that
which supports the retaining pressing roller is capable of sliding in an adjust-
able guide piece in the carrier to and from the retaining roller, but the lower
bearing, which supports the drawing pressing roller, is fixed in the carrier.
From the rear of the sliding bearing projects a pin which passes through the
carrier and stands out beyond it. The tapped end of the ordinary weighted
rod, by which pressure is imparted to the pressing rollers passes through the
carrier and through a saddle piece in front thereof, so that the binding nut on

page_text: the tapped end of the rod throws the pressure upon the saddle piece instead of
directly upon the carrier. The upper end of this saddle piece bears against
the projecting pin of the upper or sliding bearing, and the lower end, which is
provided with a series of notches, rests upon a V-edged projection at the lower
end of the carrier. According, therefore, as the saddle is shifted higher or
lower, so will the relative proportions of pressure put upon the upper and
lower rollers be changed..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Eugène Morel in the Great Seal Patent Office on the 6th
September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EUGENE
MOREL, of the City of Ghent, in Belgium, Administrator Director of the
Société de la Lys; Flax Spinning Company, in Ghent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of March, in the year of our. Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Eugene Morel, Her especial license that I, the said Eugène Morel,
my executors, administrators, and assigns; or such others as I, the said Eugène
Morel, 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 "IMPROVED MACHINERY FOR DRAW-
ING FIBROUS SUBSTANCES," being a communication from abroad, upon the con-
dition (amongst others) that I, the said Eugene Morel, 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 per-
formed, 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 Eugene Morel, 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,
reference being had to the Drawing hereunto annexed, and to the letters and
figures marked thereon (that is to say) :-

page_text: This Invention, as communicated to me by my foreign correspondent, relates
to an improved mode of distributing the amount of pressure put upon the
upper and lower pressing rollers of spinning frames.
The accompanying Drawing shews in sectional elevation so much of a
spinning frame, fitted according to this Invention, as will serve to explain the
nature of the improvement..
a and b represent two of a series of pressing rollers, a being the retaining,
pressing roller, and 6 the drawing pressing roller. These rollers, the number
of which in one machine depends upon the number of spindles required to be
fed with fibrous material, are mounted in carriers c, c, pendent from a hori-
zontal rod d, which extends the whole width of the machine; each of these
carriers is fitted with two bearings to receive the axles of the rollers a, b,
respectively. The upper bearing, or that which supports the retaining pressing
roller, is capable of sliding in a guide piece c¹, that has a vertical adjustment
in the carrier to and from the retaining roller a*, and is held fast by a clamping
screw ; but the lower bearing, which supports the drawing pressing roller,
is stationary in the carrier. Thus the roller a has a forward and backward
movement to adjust the nip on the descending sliver independently of the
pendent carrier, while the roller 6 moves with the carrier to press upon the
drawing roller 6. The bearing of the roller a has also a vertical adjustment
as usual to adapt the length of "reach" to the staple under treatment. From
the rear of the sliding bearing projects a pin e, which passes through the
carrier c and stands out beyond it, the carrier being slotted for that purpose;
the length of this slot, it will be obvious, must correspond with the length of
the reach of the spinning frame. The tapped end of adjustment in the ordi-
nary weighted rod f, by which pressure is imparted to the pressing rollers a
and b, passes through the carrier, and through a saddle piece or pressing lever g
placed in front thereof and serves to support the saddle piece. The binding
nut on the tapped end of the weighted rod f therefore throws the pressure
upon the saddle piece instead of directly upon the carrier. The upper end of
this saddle piece bears against the projecting pine of the upper or sliding
bearing and the lower end, which is provided with a series of notches, rests
upon a V-edged projection at the lower end of the carrier c. It will now be
understood that as the saddle is shifted higher or lower, the weight will press
with a greater or less leverage upon the bearing of the upper pressing roller
a, and thus the relative proportions of pressure put upon the upper and lower
rollers may be readily changed. By this arrangement it will also be seen that
one weight will serve to press both the upper and lower rollers, and that
the removal of the roller 6 may be effected without disturbing the-roller a..

page_text: Having now set forth the nature of the Invention of "Improved Machinery
for Drawing Fibrous Substances," as communicated to me by my foreign
correspondent, and explained the manner of carrying the same into effect, I
wish it to be understood, that under the above in part recited Letters Patent
I claim, the means herein-before described for distributing the amount of
pressure put upon the upper and lower pressing rollers of spinning frames in
the required relative proportions, whatever the length of "reach" employed.
In witness whereof, I, the said Eugene Morel, have hereunto set my
hand and seal, the Second day of September, in the year of our
Lord One thousand eight hundred and fifty-eight.
E. MOREL. (L.S.)
