PROVISIONAL SPECIFICATION.
Improvements in or connected with Tubes or Bobbins for use in
Warping and Beaming Machines.
We, SAMUEL HERBERT BROOKS of the Firm of Brooks & Doxey, Union Iron
Works, West Gorton, Manchester, in the County of Lancaster Machine Makers
and JAMES WILLIAM COMPSTON of the Union Iron Works aforesaid, Commercial
Traveller, do hereby declare the nature of this invention to be as follows:-
This invention relates to parallel tubes or bobbins upon which yarn is wound
in quick traverse winding frames for use in warping and beaming machines in
which the yarn wound thereon assumes the shape known as "cheese" the tube or
bobbin being without flanges or heads.
It consists essentially in the use in or application to a warping or beaming
machine of a tube provided with a groove recess or its equivalent at one or both
ends to receive a drag string or cord the drag or friction of which will prevent
over running of the yarn whilst unwinding.
The invention may be carried out in several ways.
1. The tube is constructed parallel from end to end and at or near each end
is formed a groove of V or other shape and of any desired depth into which the
drag cord is inserted.
2. The tube may be constructed parallel from end to end and at the end it may
be inclined or tapered for a short distance towards the centre terminating with a
shoulder thus forming a recess to receive the drag cord and hold it in position.
3. The tube may be constructed slightly enlarged at the ends and this enlarge-
ment turned with a groove in the centre.
4. The tube may be constructed with enlarged ends tapering towards the centre
of the tube and terminating with a shoulder or the tube may be otherwise
constructed to provide a bearing surface for the drag cord.
If found desirable a washer or disc of cardboard paper, sheet metal or other
material may
be placed loosely over the end of the tube to prevent contact of the
drag cord with the yarn.
The drag cord may be suspended from the top of or from above the creel to
engage with the tubes in succession and kept taut by means of weights or springs.
In case of weights to prevent vibration the cords may be passed through holes
or slots in a rail or they may be passed round a rail with the weight suspended
below.
It will be understood that the peg or spindle which supports the tube or bobbin
in the creel is of the ordinary construction and the tube rotates thereon..

Warping and Beaming Machines.
We, SAMUEL HERBERT BROOKS, of the Firm of Brooks & Doxey, Union Iron
Works, West Gorton, Manchester, in the County of Lancaster, Machine Makers
and JAMES WILLIAM COMPSTON, of the Union Iron Works aforesaid, Commercial
Traveller, do hereby declare the nature of this 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 the warping, beaming or sizing of yarn which has
been wound in quick traverse or cross winding frames into a form known as a
roll or "cheese upon tubes or bobbins without flanges. And it is designed to
provide for the more regular and even unwinding of the yarn from the tube by
supplying means whereby a brake may be applied and the over running of the
tube during unwinding be prevented.
In these quick traverse or cross winding frames it is customary to employ
tubes or flangeless bobbins, and these have hitherto been considered unsuitable
for warping and beaming purposes unless provided with a special form of spring
skewer or peg.
Our invention consists essentially in the use or application of such tubes to a
warping, beaming sizing or other similar machine, by constructing the same
with a groove or recess at one or both ends, and employing the same in combina-
tion with a drag string or cord drawn tightly against the groove, to give the
desired amount of friction to prevent over-running of the yarn whilst unwinding.
It will be fully described with reference to the accompanying drawings.

operation.
Fig. 2. End elevation.

Figs. 3, 4 and 5. Details of different forms of tubes showing the groove formed
in the ends.
The tube A may be of any suitable form parallel from end to end for the greater
part of its length.
At or near one or preferably both ends of the tube A is formed a groove B of
suitable shape and depth into which a drag cord D is inserted when the tube A
is placed in the creel C.
The groove B may be of any suitable shape such as V, curved, square or the
like, but at present we prefer the form shown in Fig. 3. The end of the tube may
also be raised or shaped, as shown in Figs. 4 and 5, or in any other suitable way
if desired.
The drag cord D is suspended from the top of the creel C from a hook c or in
any other suitable manner to engage with the tubes A alternately at the front and
back, in succession entering one of the grooves B in each tube A, and is kept
taut by means of weights E or by means of a spring or springs.
The weights E are preferably made with a slot e, and mounted upon a pin or
bracket F, attached to the bottom of the drag cord D so as to allow of the weight
or drag being easily regulated and adjusted as required according to the different
counts of yarn being unwound, as shown in Figs. 2 and 2. The weight or
weights may, however, be attached direct to or placed upon the drag cord as in
Fig. 1.

page_text: To prevent vibration the cords D may, with the weights attached, be passed
through holes or slots in a rail or rod, or over or round a rail or rod.
The peg or skewer G which supports the tube A in the creel C is of the ordinary
construction, and the tube may rotate thereon.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:
The use in a warping, beaming, sizing or similar machine to prevent over-
running of the yarn when unwinding, of a tube or flangeless bobbin constructed
with a groove or recess in one or both ends in conjunction with a drag string or
cord in contact successively with the tubes and with weights or springs attached
to the same, substantially as described.
