THOMAS WILLIAM SMITH, Weaver, Foley Park, Kidderminster GEORGE THOMAS,
Joiner 87, George Street Kidderminster do hereby declare the nature of our
invention for NEW OR IMPROVED BOBBIN FRAME FOR LOOMS USED IN WEAVING
CARPET to be as follows:―
Square corner'd Framo dove-taild corner's with division pieces full length of frame
groved into the ends of frame and securely nailed-The Bobbin to revolve on
Triangular blocks of wood fixed to the division pieces and to the strips of wood
underneath the division pieces. The top of the Frame is divided into divisions by
two rows of wire to each row of bobbins the wire fixed one inch apart for the weight
to hang between them on the yarn.
Square corner'd Bobbin Frame-for Loom's-to be used in Weaving Carpet The
size of Frame and the size of its divisions to be determined by the size and number of
Bobbins required each Frame.
The sides and Ends of Frame to be composed of Timber three and half inches deep
by one inch and half thick dovetailed at each corner and securely nailed. The division
pieces that go lengthways down the Frame to be composed of timber three and half
inches wide by half inch thick let into groves at each end of Frame and securely
nailed.
The Bottom of the Frame is composed of Triangular blocks of wood fixed to the
division pieces-four and three quarters of a inch apart from centre to centre, thus
giving bearings for bobbins to revolve on and also friction. Underneath these
triangular blocks and division pieces, are fixed strips of wood, the full length of frame,
one inch and three quarters wide, by one half inch thick.
The top of the Frame is divided crossways, into divisions by two rows of wire to
each row of bobbins. The wire is fixed one inch apart for the weight to hang between
them on the yarn to give the proper tension to the yarn being supplied from the
bobbins to the Carpet being wove.

page_text: We, THOMAS WILLIAM SMITH, Weaver and GEORGE THOMAS, Carpenter both of
George Street, Kidderminster, in the County of Worcester, 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:-
"
This Invention relates to certain improvements in or applicable to bobbin frames
used in looms for weaving carpets and other fabrics (hereinafter intended to be
included where the word " carpet occurs) the Invention having special reference to
improved means of supporting the bobbin and the yarn or other material (herein-
after intended to be included where the word "
yarn occurs) after leaving the bobbins
in such a manner as to ensure that the bobbins and the yarn shall be subjected to a
practically continuous even amount of frictional resistance effective in causing the
yarn to be kept at a practically uniform tension and to be drawn evenly into the
carpet resulting in the production of a carpet of uniform density with a closely woven
back and in the saving of a considerable amount of yarn.
According to the present system the peripheries of the rims of the bobbin aro caused
to rest upon a friction bar placed vertically below the axis of the bobbin, the frictional
resistance being entirely due to the gravity of the bobbin which varies in accordance
with the amount of yarn thereon and the drawing forward of the yarn tends to raise
the bobbin and to lessen such resistance and the yarn after leaving the bobbin is
passed over a single wire, so that the weight by which the tension of the yarn is to
some extent governed is not confined to any particular position, the result of such
arrangement being that the tension of the yarn is very irregular and the weight is at
liberty to shift its position and at times the frictional resistance offered to the rotation
of the bobbin is lessened to such an extent that the weight drags the yarn and falls
into contact with the yarn of the frame next below interfering with and varying the
tension of that, and the yarn is consequently drawn into the carpet with an irregular
tension and is at times puckered up thereinto, resulting in the production of a carpet
of varying density, with a loosely woven back and in the waste of a great amount
of yarn.
The present Invention consists essentially in supporting the bobbin peripherally of
its rims between V or analogously disposed supporting parts in such a manner as
that each bobbin is supported at four or more parts in lieu of only two as at present
and in such a manner as that the ascending and descending sides thereof shall simul-
taneously bear on and have frictional resistance offered to them by such supports of
the bobbin, and in such a manner as that the drawing forward of the yarn shall tend
to keep the frictional resistance offered by the said supports uniform by causing the
bobbin to be borne with a practically even bearing against those of its supports which
lie in the direction of the pull of the yarn.
The Invention also consists in combining with such an arrangement of means for
supporting the bobbins a series of parellel wires for each row of bobbins, for supporting
the yarn immediately after leaving the bobbins, such wires being arranged parallel
to the axes of the bobbins and at such a distance apart as will allow of the usual weight

page_text: suspended on the yarn working freely between the same and as will cause the weight
to maintain a practically constant position avoiding the disadvantages consequent when
only one such wire is used as hitherto, this improved arrangement being also instru-
mental in causing the yarn being supplied from the bobbin to the carpet being woven
to receive a practically continuous even tension.
On the accompanying drawings,
Fig. 1 represents a perspective view of part of a bobbin frame adapted in accordance
with the present Invention.

Fig. 2, represents a side elevation thereof in section through the line, a,
And Fig. 3. represents a transverso elevation of Fig. 1. through the line, c, d.
It will be understood that the bobbin frame may be made of any desired size
and dimensions depending upon the size and number of bobbins required to the
frame.
4, represents one end of the frame to which divisional pieces, 5, extending length-
ways of the frame are connected in any suitable manner. 7, represents the bobbins
which rotate on spindles, 8, working loosely in slots, 9, formed in the divisions, 5,
such slots being adapted with division pieces, 10, of tin or other suitable metal, all in
a usual manner.
11, represents the improved means by which the bobbins are supported, in the
manner clearly indicated in the drawings, and which in accordance with the present
Invention consist of triangular or other shaped blocks which will cause each bobbin
to have four bearing points operating in the manner herein before indicated. Such
supports may be made of wood or other suitable material and are secured (in their
proper relativo positions, at the proper distance apart, depending upon the diameter
of the bobbins) to the opposite sides of the divisions, 5, and to the top sides of
supporting strips, 12, secured to the undersides of the divisions, 5, thus affording
bearings for the rims of the bobbins to revolve on and the required frictional resistance
in the manner herein before indicated.
13, represents the aforesaid parallel wires which may run continuously across the
top part of the frame from side to side thereof and which are secured to each division, 5,
by staples or like means, 14, and being arranged as aforesaid parallel with the axes of
the bobbins are effective in supporting the yarn, after leaving the bobbin, at two
places between which the usual weight, 15, is suspended on the yarn, so that the
friction of the yarn thereover is rendered even and the position of the weight
relatively to its own bobbin is ensured.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
1. In combination with a bobbin frame, series of opposite blocks, 11, secured to
its sides or divisions arranged for supporting the bobbins peripherally of their rims,
substantially as hereinbefore described.
2. In combination with a bobbin frame having series of opposite blocks, 11, secured
to its sides or divisions arranged for supporting the bobbins peripherally of their rims
as set forth, series of parallel wires, 13, arranged for supporting the yarn immediately
after leaving the bobbins and retaining the weight, 15, between them, substantially as
bereinbefore described.
