page_text: I, CORNELIUS HENRY ROOKES, of Nash Mills, Hemel-Hempstead, Hertford-
shire, Engineer, do hereby declare the nature of this invention to be as follows: —
This invention has reference to paper reeling machinery, and has special
reference to improved means of securing the wood eels o bobbins on which
the paper is wound to the winding spindle of the reeling machine.
It is frequently requued in such machines to apply bobbins of different
lengths to the winding spindle, for which purpose, adjustable priamidal cones
adapted to enter the correspondingly shaped ends of the bobbin are applied to
the squared spindle As hitherto made, these cones have been formed with
bosses having through screw holes for the reception of screw bolts, which, by
being screwed down through the boss into engagement with recesses made in
the winding spindle, have served to secure the conos In using such device,
the cone is slid along the spindle and its tapei-squared end entered into the
correspondingly shaped end of the bobbin as far as can be done by hand, and
18 then further diven in by the cone being hammered, whereupon, the cone 18
located by screwing its sciew bolt down through its boss into engagement with
the winding spindle
This device is disadvantageous in that the hammering of the cone into the
bobbin end is able to split the latter when made of wood and unprotected by
a metal bushing, the set screws are liable to break off through over tightening
and often have to be drilled out which damages and weakens the spindle, and,
as they considerably project, they are liable to cause accidents, and the cones
cannot be accurately adjusted to all lengths of bobbins owing to the distance
between the recesses in the spindle limiting the fastening positions of the set
screws so that the bobbin is liable to be loosely held, and it is difficult to exactly
locate the screwholes over the recesses in the spindle, and the set screws are
liable to burr the spindle
The object of the present improvements is to avoid these and other disadvan-
tages incidental to such means, and, to this end, the invention consists in a com-
bination of devices whereby the cone can be exactly located in relation to a
bobbin whatever be its length, and whereby the bobbin will be held perfectly
tight
In the improved device, I employ a collar which can be freely slid along the
spindle, forming one of its ends cylindrical and with an external screw thread
and its other end conical and with an external screw thread and split the conical
end longitudinally at two or more parts. To the threaded part of each collar-
end I apply a nut with angular sides or peripheral holes by which it can be
turned, and in the face of the nut on the cylindrical end of the collar I make
a concentric projection or spigot adapted to engage with a concentric socket
or recess in the opposite face of the pyramidal cone, which latter 18 made with-

page_text: out its usual boss and can be freely shifted along the spindle when not engaged
by said opposite nut
This improved combination of devices enables the cone to be freely moved by
hand into engagement with the square tapered ecoss in the bobbin end, and of
the collar (with the nut on its cylindrical end screwed fully on, towards a central
abutment, and with the nut on its conical end unscrewed towards the small end)
being then slid along the spindle into contact with the cone, whereupon, the
collar is fixedly located in ielation to the spindle by screwing the nut on its
split tapered end fully onto its larger end, towards said central abutment, where-
upon, the nut on the cylindrical end of the collar is partly unscrewed, and, in
being ao actuated, gently but forcibly thrusts the cone home in the bobbin end,
and causes the bobbin to be accurately located and held perfectly tight whatever
be its length
Improvements in Paper Reeling Machinery.
I, CORNELIUS HENRY ROOKES, of Nash Mills, Hemel Hempstead, Hertford-
shire, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascoitained
in and by the following statement:-
-
This invention relates to paper reeling machinery, and has particular refei-
ence to improved means of securing the wooden reels o bobbins on which the
paper is wound to the winding spindle of the reeling machine
It is frequently required, in such machines, to apply bobbins of different
lengths to the winding spindle, for which purpose, adjustable pyramidal cones
adapted to enter the correspondingly shaped ends of the bobbm are applied to
the squared spindle As hitherto made, these cones have been formed with
bosses having through screw holes for the reception of sciew bolts, which, by
being screwed down through the boss into engagement with one of a series of
recesses made in the winding spindle, have beived to secure the coues
using such device, the cone is slid along the spindle and its taper-squared end
entered into the correspondingly shaped end of the bobbin as far as can be done
by hand, and is then further driven in by the cono being hammered, whereupon,
the cone is located by screwing its sciew bolt down through its boss into engage-
ment with the winding spindle

Such device is disadvantageous in that the hummeling of the cone into the
bobbin end 18 hable to split the latter when made of wood and unprotected by a
metal bushing, the set screws are liable to break off through over tightening
and often have to be dulled out which damages and weakens the spindle, and,
as they considerably project, they are liable to cause accidents, and, moreover,
the cones cannot be accurately adjusted to all lengths of bobbins owing to the
distance between the recesses in the spindle limiting the fastening positions of
the set screws, so that the bobbin is liable to be loosely held, and it is difficult
to exactly locate the screw holes over the recesses in the spindle, and the set
screws are liable to burr the spindle
The object of the present improvements is to avoid these and other disadvan-
tages incidental to such means, and, to this end, the invention consists in a

page_text: combination of devices whereby the cone can most easily be exactly located in
relation to a bobbin whatever be its length, and whereby the bobbin will be
held perfectly tight
-
The improved device is represented on the accompanying drawings, in which;-
Figure, 1, represents a sectional elevation, showing the parts detached; and
Fig 2, represents an elevation, showing the parts in position.
a, represents a collar which can be freely slid along the spindle, b, and has
one end cylindrical and formed with an external screw thread, as at a¹, and its
other end tapered and formed with an external screw thread, as at a³, and split
longitudinally at two or more parts, as at a³ The threaded parts, a¹, a³, are
respectively fitted with nuts. c, c¹, having angular sides or peripheral holes by
which they can be turned The face of the nut, c, on the cvlindrical end of the
collar is made with a concentric projection or spigot, c, adapted to engage with
a concentric socket or recess, &, made in the opposite face of a pyramidal cone, d.
This improved combination of devices enables the cone to be freely moved
by hand into engagement with the customary correspondingly shaped recess, e¹,
in the end of the bobbin, e, and of the collar, a, (with the nut, c, on its cylindrical
end screwed fully on, towards the midlength of the collar, and with the nut, c¹.
on its tapered end unscrewed towards the small end, vide Fig 1,) being then
alid along the spindle into contact with the cone, and of the collar being then
fixedly located in relation to the spindle by screwing the nut, c', on its split
tapered end fully onto its larger end, towards the midlength of the collar, and
of the nut, c, on the cylindrical end of the collar being then partly unscrewed,
and of the same, in being so actuated, gently but forcibly thrusting the cone
home in the bobbin end, thus causing the bobbin to be accurately located and
held perfectly tight whatever be its length.
The improved device is equally well applicable for use both with square spindles
and with round spindles
The screwed cylindrical part, a¹, of the collar may be fitted with a lock-nut
intermediate of the nut, c, and the collar centre part, a, and the screwed conical
pait, as, of the collar may also be fitted with a lock-nut on the outer side of
the nut, c¹
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
In devices for securing the reels o bobbins on which the paper is wound to
the winding spindles of reeling machines, in combination, a collar adapted to
slide freely along the spindle and having an external cylindrical thread at one
end fitted with a nut oi nuts and an external tapered thread at the other end
fitted with a nut o nuts and being slit at such tapered end, and a pyramidal
cone adapted to slide freely along the spindle and to fit into or engage with the
bobbin end, the opposing faces of the cone and of the adjacent nut being adapted
to engage and the whole of the parts being adapted to co-operate substantially
as herein before described
