IMPROVEMENTS IN CREEL FRAMES AND BOBBINS FOR BRUSSELS CARPET LOOMS."
Year: 1871

page_text: LETTERS PATENT to John Lamb, of Kidderminster, in the County
of Worcester, Machinist, for the Invention of "IMPROVEMENTS IN
CREEL FRAMES AND BOBBINS FOR BRUSSELS CARPET LOOMS."
PROVISIONAL SPECIFICATION left by the said John Lamb at the
Office of the Commissioners of Patents, with his Petition, on the
15th November 1871.
I, JOHN LAMB, of Kidderminster, in the County of Worcester,
Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN CREEL FRAMES AND BOBBINS FOR BRUSSELS CARPET LOOMS,"
to be as follows:-
This Invention relates to certain improvements in creel frames and
bobbins for Brussels carpet looms, and has for its object the ensuring
of greater uniformity in the tension of the yarn as it is drawn off the
bobbins in the creel during the process of weaving.
According to my Invention I combine inclined slots in the longi-
tudinal bars of the frame or creel, with inclined bearing bars below for

page_text: the bobbins to rest upon, the two inclines forming together an acute
angle with its apex downwards, and in the opposite direction to that in
which the yarn is drawn off, so that the bobbin shall have a tendency
to wedge itself between the inclines when a downward pull is put upon
the yarn, and shall tend to relieve itself and allow the yarn to unwind
easily when the pull is horizontal or in an upward direction.
The ordinary bobbins and loose pins may be used in the improved creel,
but I prefer to use my improved bobbins therewith, which improved
bobbins are provided with fixed pins or journals in lieu of loose ones. The
fixed pins may either be turned out of the material composing the bobbin
itself so as to form one piece therewith, or it may be made separately,
either of wood, metal, or other suitable material, and driven firmly into
the centre of the bobbin or otherwise secured therein. These improved
bobbins with fixed pins may obviously be used with the ordinary creels,
and in all cases will tend to equalize the tension of the yarn by reefing
the bobbin in a central position with their sides out of contact with the
longitudinal bars of the creel. I attach the cross wires of the creel, by.
looped staples or otherwise, to raised wooden cross bars, which are

wire being thus supported on wood is less liable to be bent or injured,
and by being raised above the frame it enables a shallower frame to be
used and still prevents the yarn from coming in contact with the bobbin
in front, thus again ensuring greater uniformity in the tension of the
yarn.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Lamb in the Great Seal Patent Office on
the 10th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
LAMB, of Kidderminster, in the County of Worcester, Machinist, send :
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
35th year of Her reign, did, for Herself, Her heirs and successors, give a

page_text: and grant unto me, the said John Lamb, Her special license that I,
the said John Lamb, my executors, administrators, and assigns, or
such others as I, the said John Lamb, my executors, administrators,
or 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 CREEL FRAMES AND
BOBBINS FOR BRUSSELLS CARPET LOOмs," upon the condition (amongst others)
that I, the said John Lamb, my executors or administrators, 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 John Lamb, do hereby declare the
nature of my 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 accompanying Drawings
and to the letters and Figures marked thereon, that is to say:
-
My said Invention relates to certain improvements in creel frames
and bobbins for Brussells carpet looms, and has for its object the ensuring
of greater uniformity in the tension of the yarn as it is drawn off the
bobbins in the creel during the process of weaving.
According to my Invention I combine inclined slots in the longi-
tudinal bars of the frame or creel, with inclined bearing bars below for
the bobbins to rest upon, the two inclines forming together an acute
angle with its apex downwards, and in the opposite direction to that in
which the yarn is drawn off, so that the bobbin shall have a tendency
to wedge itself between the said inclined surfaces when a downward pull
is put upon the yarn, and shall tend to relieve itself and allow the yarn
to unwind easily when the pull is horizontal or in an upward direction.
The ordinary bobbins and loose pins may be used in the improved
creel, but I prefer to use my improved bobbins therewith, which
improved bobbins are provided with fixed pins or journals in lieu of
loose ones. The fixed pin may either be turned out of the material
composing the bobbin itself so as to form one piece therewith, or it may

page_text: be made separately either of wood, metal, or other suitable material,
driven firmly into the centre of the bobbin or otherwise secured therein.
These improved bobbins with fixed pins may obviously be used with the
ordinary creels, and in all cases will tend to equalize the tension of the
yarn by keeping the bobbin in a central position with their sides out

wires of the creel, by looped staples or otherwise, to raised wooden cross
bars, which are by preference notched on the under side so as to fit in
between the longitudinal bars, and thereby maintain them at the proper
distance asunder. The cross wire being thus supported on wood is less 1
liable to be bent or injured, and by being raised above the frame it
enables a shallower frame to be used and still prevents the yarn from
coming in contact with the bobbin in front, thus again ensuring greater
uniformity in the tension of the yarn.
And in order that my said Invention may be fully understood, I 1
shall now proceed more particularly to describe the same, and for that
purpose shall refer to the several Figures on the annexed Sheet of
Drawings, the same letters of reference indicating corresponding parts
in both the Figures.
Figure 1 of my Drawings represents a sectional elevation of a portion a
of my improved creel frame with an ordinary, and with one of my
improved bobbins therein, and Figure 2 is a corresponding plan of the
same.
A, A, are the longitudinal bars of the creel frame; B, B, are inclined
slots made in the inner faces of the said bars; O, O, are the inclined
bearing bars for the flanges of the bobbins D, D¹, to rest upon, such
bars C being notched on to the under sides of the longitudinal bars so
as to impart stability to the entire frame. The acute angle formed by
the two inclined surfaces of the slot and bar is clearly indicated by the
dotted lines at a in Figure 1. D represents the ordinary bobbin with
loose pin or centre applied to my improved frame, and D' represents my
improved bobbin with a fixed pin or centre, which I prefer to use in
connection with the improved frame. b, b', represent the fixed centres
of the bobbin, which may be made either by driving a stud b tightly
into the bush of the bobbin, or by turning the centre out of the solid
wood, as shown at b¹. E, E, are the raised wooden cross bars for
carrying the wires c, the said bars being made to increase the general
stability of the creel frame by being notched on the under side so as to

page_text: fit over the upper edges of the longitudinal bars A, and thus act as
distance pieces or stays between each two bars.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is,-
First. The combination in a creel frame of inclined slots with inclined
surface bearing bars, arranged so as to form an acute angle together, in
the manner and for the purpose herein-before described and illustrated
by my Drawings.
Second. The construction and use of bobbins for creel frames, having
fixed pins or axes substantially as herein-before described.
Third. The mounting the wires for creel frames upon raised wooden
cross bars substantially as and for the purposes herein-before described.
In witness whereof, I, the said John Lamb, have to this my
Specification set my hand and seal, the Fourth day of May, One
thousand eight hundred and seventy-two.
