Improvements in Machinery or Apparatus for the Manufacture of
Spiral Cop Tubes.
I, ARTHUR SMITH MILLS, of 43, York Street, Heywood, near Manchester, in
the County of Lancaster, Bank Clerk, do hereby declare the nature of this inven
tion to be as follows:-
This invention relates to improvements in machinery or apparatus for the
manufacture of spiral cop tubes upon which yarn or thread is spun or wound and
has for its object to facilitate the manufacture of the same.
To this end the invention consists principally in the employment of two spindles
in certain novel positions to each other, to the paper from which the tubes are
made and to the shears, as well as in certain shapes of primary and secondary
shears by which the paper is severed. The spindles are both placed at the opposite
end of the machine to the end at which the paper is brought in pasted and delivered
between the shears.
Both spindles are moved up to the paper from which the tubes are formed, in a
similar direction but not moving up parallel to one another, each pointing towards
the centre line of the paper, but not merging at one point in that line.
The angle at which the spindles are placed to each other, to the paper, and
to the primary and secondary shears, being regulated by the length of paper
wound round the spindle in forming the tube and the amount of taper given to
the tube.
The primary shears sever a slip from the paper delivered into the machine from
the roll, the paper heing delivered between the shears, by suitable arrangements,
the same distance as the length of tube required. The primary shears have their
cutting edges formed by portions of two circles of equal radius and having their
centres in the centre lines of the two spindles. The secondary shears, by which is
severed diagonally the slip delivered through and severed by the primary shears,
has cutting edges forming a portion of a circle equal in radius to the radii of the
two circles forming the primary shears.
The slip thus being severed in two parts, the spindles move up, take hold of
their respective slips and the tubes are then wound on and stripped from the
spindles in the usual way. The tubes being made without cutting to waste the
paper.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for the Manufacture of
Spiral Cop Tubes.
I, ARTHUR SMITH MILLS, of 43, York Street, Heywood, near Manchester, in
the County of Lancaster, Bank Clerk, 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 improvements in machinery or apparatus for the
manufacture of spiral cop tubes upon which yarn or thread is spun or wound and
has for its object to facilitate the manufacture of the same.
And in order that my invention may be more fully understood I have caused to
TD027

page_text: be appended hereunto two sheets of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1, Sheet I, is a plan of the machine with spindles positioned and shears
constructed in accordance with my invention.
Fig. 2 is a detached sectional end view and Fig. 3 a sectional side view of the
shearing device thereof.
Fig. 4 is a detached plan showing the bottom or stationary parts of the shears.
Fig. 5 is a plan of a strip of paper cut from the roll and severed diagonally into
two parts ready to be taken up by the spindles.
Fig. 6 is an elevation of a tube finished.
In carrying out my invention and referring to Fig. 1, the improvements consist
principally in the employment of two spindles a & b, in certain novel positions to
each other, to the paper e from which the tubes are made and to the shears d, d¹, e, e',
as well as in certain shapes of the primary and secondary shears d, d, e, e', by
which the paper c is severed. The spindles a & b are both placed at the opposite
end of the machine to the end at which the paper c is brought in pasted and
delivered between the shears d, d¹, e, e¹.
Both spindles a & bare moved up to the paper c from which the tubes are
formed, in a similar direction but not moving up parallel to one another, each
pointing towards the centre line f of the paper e but not necessarily merging at
one point in that line.
The angles at which the spindles a & b are placed to each other, to the paper c
and to the primary and secondary shears d, d', e, e¹, respectively, being regulated
by the length of paper wound round the spindles in forming tubes and the amount
of taper given to the tubes.
The primary shears d, d', sever a slip c¹ from the paper c delivered into the
machine from the roll, the paper being delivered between the shears d, d¹, e, e¹, by
suitable feeding arrangements, for instance, such as shown in the drawing annexed,
the same distance as the length of tube required. The primary shears d, d¹, see
also Figs. 2, 3, & 4, have their cutting edges formed by portions of two circles of
equal radius 9 and having their centres 9' in the centre lines a', 6', of the two
spindles a & b. The secondary shears e, e', by which is severed diagonally the
slip c delivered through and severed by the primary shears d, d', has cutting edges
forming a portion of a circle equal in radius to the radii of the two circles
forming the primary shears d, "d', having its centre ¹ in a line i parallel to the
centre line of the paper c.
The slip c¹ thus being severed in two parts, the spindles a & b move up, take
hold of their respective slips and the tubes are then wound on and stripped from
the spindles in the usual way. The tubes being made without cutting to waste the
paper.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
"In machinery or apparatus for the manufacture of spiral cop tubes."
1st. The general construction and combination of parts constituting my
improvements operating substantially as and for the purpose set forth.
2nd. Positioning the spindles a & b in relation to the paper strip c¹ in such a
manner that their centre lines a¹ & 1 point towards the centre line of the paper
strip c but not necessarily merging at one point in the line f, substantially as and
for the purpose set forth.
3rd. In combination with the spindle arrangement specified in the preceding
claim, primary shears d, d', having each a cutting edge formed by portions of two
circles of equal radii g and having their centres g' in the centre lines a¹, 6¹, of the
two spindles a & b; substantially as and for the purpose set forth.
4th. In combination with the spindle arrangement specified in the preceding
claims, primary shears d, d', having each a cutting edge formed by portions of two

page_text: circles of equal radii 9 and having their centres g' in the centre lines a², 61, of the
two spindles a & b, secondary shears e, e', having cutting edges which form each a
portion of a circle equal in radius to one of the radii g of the portions of the
circles which form the primary shears d, d', and the centre ' of which is in a line i
parallel to the centre line of the paper c, substantially as and for the purpose set
forth.
