enters, the brass is at right angles to the drill, while the holes.come out on the
outer surface, at 'the required 'angle. It has, hitherto been impracticable within.

Improvements in the Comb Cylinders of Combing, Machines for-
Cotton, Wool, and other Fibres.
I, THOMAS, WALTER, HARDING.of The Tower Works, Globe Road, Leeds in
the County of York Engineer 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 :-
"Heilmann's."
My invention relates to machines of the type originally known as
For these machines the comb cylinders are built up of segments or strips
overlapping each other in an inclined position; with a row of pins soldered to the
edge of each.

propose to make these segments of such section that they may be screwed
radially to the cylinder so that any one of them may be removed for repairs
without disturbing the others; and fitted with flanges at top which present a
continuous surface when the segments are screwed together. The flanges are so
shaped that rows for pins may be readily drilled in them, because at the back where
the drill enters, the brass is at right angles to the drill while the holes come out on
the outer surface at the required angle.
In order that the tops of the segments, forming a continuous surface, may have
the required eccentricity I propose to screw the segments upon an eccentric shell
which will be screwed to the cylinder.

page_text: The accompanying drawing af Fig. 1 shews longitudinal elevation and at
Fig. 2 a transverse section of a comb cylinder constructed on my plan.
A is the cylinder, B is the eccentric shell which is screwed to the cylinder by
the screws D D. EE are the segments which are screwed to the eccentric shell
by the screws F F. G G are the rows of pins which are inserted through the
flanges of the segments at right angles to their backs. From this description it
will be readily seen that when it is required to remove any of the segments for
repairs, the eccentric shell B and the segments E may be removed complete by
unscrewing the screws D and any of the segments may be unscrewed from the
shell B without disturbing the others. This arrangement has the advantage that
the segments E are all alike in section, but the most important advantage of this
section or form of segment is the facility it offers for drilling the rows of holes into
which the pins are to be inserted.
On account of the great angle required in these combs it has hitherto been found
impracticable within reasonable. limits of cost to produce combs with drilled rows
of pins. Now the V section which I give to the flange of the brass segment
permits me to drill rows from the back, and it will be seen that a drill entering the
brass from the back (that is from the part where the roots of the pins are shewn in
the drawing) would enter the brass at right angles and that thus would be removed
a great part of the difficulty hitherto met with in drilling where the drill had to
enter the brass at a great angle. This ✓ section of brass also offers the advantage
that the pins can be readily filled from the back, and that when repairs are necessary
the pins can be got hold of by an ordinary pair of pliers and withdrawn from the
back. This section of brass for facilitating right-angled drilling of the rows of
pins can also be applied to the old form of segments in which the segments are
screwed on to a cylinder and the eccentric surface obtained by varying the
projection of the segment over the cylinder..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be. performed, I declare that what I
claim is
1. A comb cylinder in which the segments E are screwed radially upon an
eccentric shell B in such a manner that they present a continuous surface and
permit of any of their number being removed without disturbing the remainder
substantially as described and shewn.
2. Drilled and pinned segments for comb cylinders of such a form or section that
the holes in which the pins are inserted can be drilled at right angles to the brass
at the back substantially as described and shewn.
3. In comb cylinders the use of an eccentric shell so formed that the segments
may be all of one section and yet present on their tops the requisite amount of
eccentricity substantially as described and shewn.
