"IMPROVEMENTS IN MACHINERY TO BE EMPLOYED IN THE MANUFACTURE OF
SPOOL TUBES."
This Invention relates, firstly, to the use of improved apparatus for cutting the
lengths of paper from which a tube is to be made. The said apparatus consists of a
toothed or serrated blade or comb which, after passing through the paper, enters a
recess or longitudinal groove formed along the periphery of a roller which supports
the paper during the operation of cutting. Secondly. To improved apparatus for
supplying ink to the tube marking type. I employ a roller, hollow, inade of
perforated zinc or other perforated sheet metal, the roller being enclosed in a
wrapping or covering of woven fabric. The ink is supplied to the interior of the
roller, and gradually ooses through the outer covering which runs in contact with
the type.
For printing designs in colours in the paper previous to making the tubes, I
employ a revolving drum partly immersed in color, the drum, being perforated with
such designs as are to be printed or stained on the spool paper.
Thirdly. In the manufacture of two tubes in one machine, I impart to the
spindles an alternate reciprocating motion, the pasting belt and its guide roller or
rollers having a reciprocating motion given thereto so as to deliver to the spool
spindle a paper during the time the other or wrapped paper is being doffed or
removed.
Fourthly. In machines employed in the manufacture of conical tubes the papers
are fed by hand (or mechanically) to a table or platform. One of the belts between
which the paper is received for conveyance to the tube spindle is raised and lowered
by means of an eccentric and lever. When raised the paper is received between the
two belts wherein the one belt closes upon the other holding the paper between
D1021

page_text: them and guiding the same to the spindle around which it is to be wrapped. One
of the rollers for drawing the required length of paper has two diameters, that is to
say, part of its circumference is of greater diameter than the other part, so that
during each revolution it will be in contact with another draw roller, passing the
paper forwards; the other part of its revolution there will be space between the
rollers in order that the papor may not be acted upon; this feed motion will be
placed in some cases at right angles to the conical tube appliances as above
described, india rubber sponge being employed as a covering for the roller or
rollers for laying the paper upon the spindle. The knife employed in connection
with the manufacture of conical tubes I construct with two blades placed at such
angle in relation to each other as that the required length of paper is cut from
the continuous length and also subdivided for the making of two conical tubes.
Fifthly. In the manufacture of conical tubes having a flange at one end similar
to a spool bobbin I expand the larger end, and by means of a disc revolving in glue
or gum impress a recess or groove around the tube for the reception of a washer or
disc forming the flange of the spool.
For drying the spools so as to retain their form each as "doffed" or removed
from the spindle is received upon a pin connected with an endless chain, by
preference working vertically, and enclosed within a drying cylinder or case heated
by gas, hot air, or otherwise."
For cutting the paper to the required width I employ rollers, one having a flange

WILLIAM AMBLER, of Bradford, in the County of York, Machine Maker,
"IMPROVEMENTS IN MACHINERY TO BE EMPLOYED IN THE MANUFActure of
SPOOL TUBES,"
This Invention relates, firstly, to the use of improved apparatus for cutting the
length of paper from which a tube is to be made. The said apparatus consists of a
toothed or serrated blado or comb which, after passing through the paper, enters
recesses or circumferential grooves formed around the periphery of a roller which
supports the paper during the operation of cutting. Secondly. To improved
apparatus for supplying ink to the tube marking type. I employ a roller, hollow,
made of perforated zinc or other perforated sheet metal, the rollers being enclosed
in a wrapping or covering of woven fabric. The ink is supplied to the interior of
the roller and gradually perculates through the outer covering which runs in
contact with the type. Thirdly. In the manufacture of two tubes in one machine
I impart to its guide or reciprocating motion, the tube being stripped or removed
from the spindle by means of a portion of the diameter of a stripping roller.
Fourthly. In machines employed in the manufacture of conical tubes the papers
are fed by hand (or mechanically) to a table or platform. One of the belts between
which the paper is received for conveyance to the tube spindle is raised and lowered
by means of an eccentric and lever. When raised the paper is received between
the two belts, whereon the one belt closes upon the other, holding the paper
between them and guiding the same to the spindle, around which it is to be
wrapped, on a longitudinal projection or ridge is employed for leading in the
papers. One of the rollers for drawing the required length of paper has two
diameters, that is to say, part of its circumference is of greater diameter than the
other part, so that during each revolution it will be in contact with another draw
roller passing the paper forwards; during the other part of its revolution there
will be space between the rollers in order that the paper may not be acted upon;
this feed motion will be placed in some cases at right angles to the conical tube
appliances, as above described, india rubber sponge being employed as a covering
for the roller or rollers for laying the paper upon the spindle. The knife employed
in connection with the manufacture of conical tubes I construct with two blades,
placed at such angle in relation to each other as that the required length of the
paper is cut from the continuous length, and also subdivided for the making of
two conical tubes; or such blades are secured at proper angles to the periphery of
a roller having two diameters.
Fifthly. In the manufacture of conical tubes having a flange at one end similar
to a spool bobbin I expand the larger end, and by means of a disc other discs
revolving in glue or gum impress a recess or groove around the tube for the
reception of a washer or disc forming the flange of the spool. For drying the
spools so as to retain their form each as "doffed" or removed from the spindle is
received upon a pin connected with an endless chain, by preference working
vertically, and enclosed within a drying cylinder or case, heated by gas, hot air, or
otherwise.
For cutting the paper to the required width I employ rollers, one having a flange
thereon, the outer edge or angle of the flange forming the cutting edge.
Such being the nature and object of this my said Invention I will now proceed
to describe the same in detail, and in order that the same may be fully understood
I have hereunto annexed 6 Sheets of Drawings, and have marked the same with

page_text: figures & letters of reference, and would observe that in many of the views or
Figures of the Drawings a part only of the machine is shewn, but in all instances
sufficient is illustrated to render the application to a spool machine of such
Invention clear and intelligible to persons practically acquainted with such
machines.
The apparatus employed for cutting the length of paper from which a tube is
to be made, Sheet 1, is shewn by Figure 1. At A is a blade, toothed or serrated,
mounted in the revolving roller or shaft B; the paper C passes over the roller D,
the periphery of which is provided with circumferential grooves to correspond with
'the cutting teeth of the knife A, so that at each revolution of the said knife its
teeth pierce the paper, serrating and cutting off the required length.
The apparatus for supplying ink to the type employed (Sheet 1) for printing on
tubes is shewn at Fig. 1 in position, and at Fig. 4 is a detail Drawing about full
size. A is the hollow roller of zinc perforated and covered by woven fabric or
felt B; the roller is mounted upon the hollow shaft C, having outlets D. As ink is
supplied by way of the funnel E it passes to the hollow shaft C and out at the
passages F to the interim of the roller, thence through the perforating and outer
covering of cloth or felt to the type or an india rubber inking roller as ordinary.
The apparatus employed in the manufacture of two tubes is illustrated by
Fig. 1, Sheet 1. At A is the endless belt; B, B¹, are the two spindles on which
the tubes are wrapped; C is a lever having T head and upper arm carrying guide
rollers D. The lever C receives a rocking or reciprocating motion from the pin E
in the end of the main or driving belt roller F of the machine, so that when a
length of paper has been wound on the spindle B and the lever C is thrown
over to spindle B', while on B the tube is doffed and there is a space between the
belt A and the spindle B for the passage of the paper forward to the spindle B¹.
At Fig. 2 is shewn like apparatus, but in which in lieu of the lever C an eccentric
roller H is employed, over which the belt A passes, that at each half revolution of
the said roller H the belt will be carried from one spindle to the other. At K is
shewn a roller having two diameters; this is employed for stripping or doffing the
spool off the spindles B. The larger diameter of the roller K has a groove cut
therein corresponding to about the diameter of the tube on the spindle, and as this
groove, by the rotation of the disc K is caused to bear upon the tube, its motion by
friction draws or slides the spool tube off the spindle, whilst its smaller diameter
affords time and space for the wrapping of the next tube paper upon the spindle.
The apparatus for hand feeding the papers to the machine is shewn at Figs.
4,5, & 6, at Sheet 2. In the manufacture of conical tubes is shewn at Figs. 7 and 8
the attendant places a paper A on the table B, and on this being advanced
forwards the roller C, a ridge or tongue extending longitudinally on the periphery
of the said roller at each revolution serves to denote the correct time, the
succeeding paper is to be fed into the machine, and also bears upon and carries the
paper between the roller C and the endless belt E, whence it passes to the spindle F,
around which wound and formed into a tube. At Fig. 5 is shewn the apparatus
whereon the belts E and G, between which the paper is received, are opened for
the reception of each necessary plate, and closed by means of the action of the
eccentric H operating the arms J and K; the concentric part of the excentric H
permits the arm J to fall or lower, so raising the arm K and its roller L, providing
space between rollers L and M for the admittance of the papers.
The mechanical feed and cutting apparatus is shewn at Figs. 1, 2, 3, at Sheet 3,
used in the manufacture of conical tubes is shewn at Sheet
by end and side
elevation and plan. At A is a reel of paper passing between the guide rollers B, B,
and under the draw roller C at D is a roller having two diameters, the larger
serving to draw the required length of paper and also to cut the same across and
obliquely, as shewn by dotted lines, thus formning the angular papers for two conical
tubes. The cutters are shewn at E, F, Figs. 4 & 5, and consist of two blades
partly imbedded in the said roller, but leaving the cutting edges protruding.
At G, G, are two other rollers having two diameters; the larger diameter bears

page_text: upon and feeds forward the paper upon the table H. J being a like roller, the two
papers are thus fed to the two spindles K, K, a portion of the roller M at N is
formed of india rubber sponge and bears upon the paper during the time the latter
is being wound around the spindles K, K, whereon the diagonally rubber portion P
revolves against the tube, and by reason of the angle of the ribs pushes or slides
the spool tube off that spindles; paste is fed to the portion N from the trough R by
means of the roller S which revolves in the paste. At T is the gearing for
imparting motion to the rollers M, D, and B, the spindles K by any convenient
going part of the machine.
The apparatus employed in the manufacture of conical tubes provided with
flanges after the manner of spool bobbins is shewn at Figs. 1 and 2, on Sheet 4.
A and B are revolving disc and drum carrying a series of spindles C; the disc A
imparts to the spindles rotation by frictional contact therewith, so that on the
proper spools being placed by the attendant on the ends D of the spindles C and
forced against the lower end of the bell shaped end of the said spindles, the lower
end of the tube is expanded; the spindles and tube then passes into contact with
the edge of the revolving disc E which indents, and so form a groove in the outer
surface of the tube, and also supplies to the groove gum or other adhesive liquid,
the latter being fed to the disc E by a similar disc F revolving in a trough or
gum supply G, the motion being obtained by pulleys and strap H. At J is a
cylinder containing the flanges, and arranged so that as the point of each spindle D
arrives under the flanges (the latter being, as shewn, in an oblique position) enters
the hole or perforation in the centre of a flange S and carries off a flange, and on
moving forward the flange S is by the incline K. gradually forced down the tube
and to the groove, the continued rotation of the disc brings the flange of the tube
upon the foot of the incline L, and in ascending the tube is pushed off the spindle.
The disc A has a separate motion or rotation imparted by means of the internal
shaft M. and pulleys N, the outer run B is driven by the hollow shaft P and
pulley R.
The apparatus employed for facilitating the drying of the tubes is shewn by
Sheet 4, Figs. 3 and 4, in which A is the spindle on which the spool tube is
formed; B, the sliding doffer which pushes off the tubes; at C is an endless chain,
having thereon a series of pins or pegs D; the latter are arranged at distances apart
or so timed as to be opposite the end of the spindle F when a tube is being pushed
off, and being received on the pin or peg D, are carried round until arriving at
the point G, whereon they slide and drop off the pin_or pegs into a receptacle.
The upper part of the endless chain C and its pulley H are enclosed and supplied
with hot air or gas to facilitate "setting" off the tube before arriving at the
point G.
Figs. 1 and 2 shew the apparatus employed for cutting the paper to the required
width, Sheet 5; A is a shaft, on which are invented a number of pulleys B, the
flanges C of which are formed with square cutting edges. The paper to be cut is
fed between the pullies A and D, and is cut between the edge of the flange C and
the outer E of the pulley D; the pullies B and D are adjustable on their respective
shafts, so as to cut any required width of paper. In order to correctly time the
rotation of the taking up rollers F on which the paper as cut is wound, the axis of
the roller F at each end is supported on an incline bearing G. The frictional
contact of the roller D imparts rotation to the winding F at an uniform relative
surface speed; but in order to provide against the slipping of the reel Ę an endless
band or strap H is passed over the pullies J, J, J, the lower pulley J having its
axis in the slot K, and a weight L is applied into the axis of the pulley.
Figs. 1, 2, and 3, on Sheet 2, shew cutting rollers employed in the manufacture of
a conical tube formed by cutting an angular strip from the corner of a square or
rectangular paper spool tube, shewn at A; B and C are the rollers, C having an
angular groove around its periphery, B having a corresponding projecting cutting
flange, which works in the groove at D is the paper passing through the machine;

page_text: E is a roller provided with pins or cutter for separating the papers into lengths;
the angular strip cut out is shewn at F.
The tube shewn at J is suitable for spicket of taps for liquid, Sheet 6.
Having thus fully described the nature and particulars of this my said Invention,
together with the manner in which the same is to be or may be performed or carried
into practical effect, I would have it understood that in order to fully illustrate my
Invention I have of necessity shewn in the Drawings many parts which are not
