PROVISIONAL SPECIFICATION.
Improvements in the Bobbin or Spool Carriers for Looms for Weaving
Tufted Carpets and the like.
I, GEORGE WILLIAMS, Axminster Tube Manufacturer, residing at 8, Swan
Street, Kidderminster, in the County of Worcester, do hereby declare the nature
of this invention to be as follows:-
This invention relates to the bobbin racks and feed bars of weaving machines,
and particularly to those used in the weaving of Axminster and similar carpets,
and has for its object an improved method of attaching the length of tubes to
the wooden bar or body part which carries them, the said method being such as
to render the attachment more strong and the whole of the tubes and wooden
body bar more rigid against any bending or twisting strain which may cause the
shape and pitch of the tubes to be damaged and irregular.
According to this invention the length of tubes are attached to the wooden
carrier bar by an L or similar sectioned metallic piece which rigidly carries
them and which runs the full length of the said wood bar, fits nicely over it, and
is nailed or screwed thereto on two or more of its sides or faces. The said strip
is preferably attached to the underside of the said wooden bar and to the top
side, but may, if necessary, be also connected on one of its edges; so that
practically the said wooden bar is stayed by this strip for half its cross sectional
circumference.
The length of tubes are soldered onto a set-back ledge formed upon the crown
of the metal strip, and a ridge is formed adjacent to this ledge over which the
material fed through the tubes can play, this ridge dispensing with the length
of wire which is now sometimes attached for this purpose.
In attaching tubes according to this invention no nailing through any part of
the said tubes is necessary, which frequently knocks the said tubes about, and
no back stiffener is required to strengthen the wooden bar, whilst the tubes are
supported at the point, viz.:--at their entrance, where they most require to be
rigid.

page_text: of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement; -
This invention relates to the bobbin or spool carriers of looms used for weaving
tufted and similar carpets, and has for its object an improved method of attach-
ing the length of tubes thereof to the wooden carrier-bar or body-part which
carries it; the said method being such as to render the said attachment more
strong, the wooden carrier bar more rigid against any bending or twisting strain,
and to better support the tubes. to prevent their pitch and shape being damaged
or becoming irregular.
it
According to this invention the length of metal tubes is attached to the wooden
carrier bar by an L or similar sectioned metal strip running the full length of the
said carrier bar and the tubes, the said strip fitting nicely over the said bar
and being fixed thereon by nailing or screwing on two or more of its sides or
faces, the said length of tubes being soldered onto the L-sectioned strip, pre-
ferably upon a set-back ledge. This set-back ledge forms a rounded or curved
ridge upon the top or crown of the strip adjacent to the mouths of the tubes, over
which said ridge the yarn or other material fed to the tubes can play. This
ridge is a non-cutting guiding edge dispensing with the length of circular wire
which hitherto has been generally used for this purpose.
is
In the accompanying sheet of drawings the invention is shown carried into
practical effect in one form in Figs. 1, 2, 3, and 4, and in another a slightly
modified formin. Figs. 5 and 6. Fig. 1 is a top. side elevation of a spool
carrier complete; Fig. 2. is a transverse section thereof; and Figs. 3 and 4 the
principal parts of Fig. 2, as according to this invention, separated.. In these
figs., is the length of tubes soldered to a L or angular sectioned metal, strip c
running from end to end of the said length of tubes. A. set-back ledge
provided upon the strip to constitute an edge and side seating for the length
of tubes a near their mouths a², and a circular ridge is formed upon the said
strip, adjacent to the, said, mouths, over which the yarn or other, material from
the bobbin can play as it enters the tubes. d is a wooden, carrier-bar having
attached to its end the usual bobbin-supporting brackets,, as represented by
Fig. 3. The cross-sectional shape of this wooden carrier bar is on its sides d³, d,
identical with the cross-sectional shape of the strip, as aforesaid, it having a set-
back part d upon its face to correspond to the set-back part 2 of the L-sectioned
strip. The strip c is nailed or screwed onto the carrier bar in the manner clearly
shown by Figs. 1 and 2. and practically embraces and stays the said bar for more
than half its cross-sectional circumference.
It will be clearly seen that the length of tubes is not nailed through onto the
carrier bar at. any point, it being intact, but the nailing is through the strip to
which it is soldered; therefore the shape of the said tubes, especially at their,
mouths, or entrances, (important parts), is preserved, and their mouths are
strengthened by the strip c..
1
In connecting the tubes to the carrier bar d in the manner described the
usual back stiffener is dispensed with, whilst the carrier bar is rendered much
more rigid and strong than hitherto, and more soldering surface is given the
length of tubes; the latter ensuring the said tubes being better supported.
In the modification Figs. 5 and 6, the L-sectioned, strip c is formed of two
parts, e, instead of by one part as in Figs. 1 to 4, but practically the same
amount of soldering surface for the length of tubes a is given upon the said strip.
In this modification, Fig. 6 shows in longitudinal underside elevation how the
stripe is attached to the length of tubes.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that..what
I claim is―
First. In bobbin carriers for carpet weaving looms, connecting the length of

and for the purpose described and substantially as set forth.
Second. A bobbin carrier for carpet weaving looms and the like constructed,
provided and fitted with in the manner described and set forth in Figs. 1 to 4
and in Figs. 5 and 6.
