PROVISIONAL SPECIFICATION.
Improvements in Injection Tubes, Skewers, or Spindles employed in
Machines for Dyeing or otherwise Treating Yarn in Cop or other
Compact Form.
We AUGUST GRAEMIGER, of Bent Street, Cheethain, Manchester, Chemist, EVAN
ARTHUR LEIGH, of 37, Cross Street, Manchester, Engineer, and SAM MASON, Jun.
of 2, Saint Ann's Place, Saint Ann's Square, Manchester, Engineer, all in the County
of Lancashire, do hereby declare the nature of this invention to be as follows
--
Our invention relates to improvements in hollow perforated injection tubes, skewers
or spindles which are employed in machines for dyeing, bleaching, scouring or other-
wise treating yarn in cop, bobbin top or other compact form and which serves to hold
and permit of the liquor being drawn or forced through the same by suitable
means.
The object of our invention is to form a better joint between the open end of the
hollow perforated injection tube, skewer or spindle and the cop, bobbin or top carrier
or its nipple and increase its suction or pressure surface, thus attaining a much better
result in the treatment of the cops, bobbins or tops.
Heretofore the open end of the hollow perforated injection tube, skewer or spindle
has been formed wider at its extreme, than at its inner end, now our invention consists
in forming the same in a reverse senso, viz. narrower at its extreme than at its inner
end and placing the same, when nipples are used inside instead of outside the same,
which ensures a tighter joint and compensates for the wear and the difference, which
may exist in the size of the holes in the cop, bobbin or top carrier or its nipples.

COMPLETE SPECIFICATION.
Improvements in Injection Tubes, Skewers, or Spindles employed in
Machines for Dyeing or otherwise Treating Yarn in Cop or other
Compact Form.
We AUGUST GRAEMIGER, of Bent Street, Cheetham, Manchester, Chomist, EVAN
ARTHUR LEIGH, of 37, Cross Street, Manchester, Engineer, and SAM MASON, Jun.,
of 2, Saint Ann's Place, Saint Ann's Square, Manchester, Engineer, all in the County
of Lancaster, 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 :-
Our invention relates to improvements in hollow perforated injection tubes, skewers,
or spindles which are employed in machines for dyeing, bleaching, scouring, or other-
wise treating yarn in cop, bobbin, top or other compact form and which serves to hold
and permit of the liquor being drawn or forced through the same by suitable means.
The object of our invention is to form a better joint between the open end of the
hollow perforated injection tube, skewer, or spindle and the cop, bobbin, or top carrier
or its nipple and increase its suction or pressure surface, thus attaining a much better
result in the treatment of the cops, bobbins or tops.
Heretofore the open end of the hollow perforated injection tube, skewer, or spindle,
has been formed wider at its extreme than at its inner end, now our invention consists
in forming the same in a reverse manner, narrower at its extreme than at its inner
ead and placing the same, when nipples are used, inside instead of outside the same:

may exist in the size of the holes in the cop, bobbin, or top carrier or its nipples.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a side elevation of a cop or bobbin injection spindle or skewer and nipple
formed and employed ns heretofore has been the case.
Fig. 2 is a side view of the lower portion of the said injection spindle or
skewer and
Fig. 3 a side view of the nipple detached therefrom.
Fig. 4 is a side view of a cop or bobbin injection spindle or skewer and nipple
employed and arranged in accordance with our invention.
Fig. 5 is a side view of the lower portion of the said injection spindle or
skewer and
Fig. 6 a sido view of the nipple detached.
Fig. 7 is a side view of our improved injection spindle or skewer fitted into the cop
or bobbin carrier itself, instead of into a nipple fixed thereon.
Figs. 8&9, are side views of an injection tube for wool tops formed accordingly to
our invention & shown employed, respectively with or without nipple.
In carrying out our invention and referring to the Figs. 4, 5, 6, 7, 8 & 9, we form
the open end of the hollow perforated injection tube, spindle or skewer a narrower at
its extreme end b than at its inner end c and place the same either into nipples d, as
shown in Figs. 4, 5, 6 & 8, or into corresponding holes e formed in the cop, bobbin, or
top carrier, as shown in Figs. 7 & 9, instead of in a reverse manner, as shown in
Figs. 1, 2, & 3, and heretofore has been the case.
Thus a much tighter joint between the cop, bobbin or top injection tube, skower, or
spindle and their nipples, or the cop, bobbin or top carrier and consequently a greater
suction or pressure surface is obtained, which is a very important feature, to ensure
the liquor to thoroughly and uniformly impregnate the cops, bobbins or tops.
The described improved form of cop, bobbin or top injection tube, skewer, or spindle
will also permit of compensating for any wear or difference in the size of the holes e
in the cop, bobbin or top carrier f, or its nipples.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In injection tubes, skewers, or spindles employed in machines for dyeing or other-
wise treating yarn in cop or other compact form."
1st. Forming the open end c of the injection tube, skewer, or spindle a, taper or
conical and smallest in diameter at its open end or mouth b, substantially as and for
the purpose specified.
2nd. The cop, bobbin or top injection tube a formed, as described in the preceding
claim, in combination with the nipple d or hole e in the cop, bobbin or top carrier f,
substantially as and for the purpose set forth.
