Improvements in Spooling Machines.
We, JAMES MCILRAITH, of 3 Prospect Villas, Blackley, in the County of
Lancaster, Millwright, and WILLIAM AYRTON of Gorebrook Ironworks, Longsight,
Manchester, Machine Maker, do hereby declare the nature of this invention to be
as follows:
This invention relates to certain classes of spooling machines and is designed
with the object of providing mechanism whereby the operations of cutting a nick
in the spool, fastening the end of the thread therein, and cutting the end of. the
thread may be performed.
We apply to each spindle a knife chisel or cutting appliance operated by a lever
and cam to nick the flange of the spool. A movable finger operated by a rack and
pinion or by a lever or other device to catch and draw the thread over across, the
Hange of the spool and under a book, a hook operated by a slotted lever or by a
quadrant and rack to catch upon the thread to draw it down into the nick and then
against a knife blade to cut it and a stationary or movable knife blade these
several parts being actuated by cams, cranks or eccentrics placed on the same
shaft or spindle so that by one revolution of movement of this spindle the several
operations will be carried out consecutively.
At or near the spindle upon which the spool is placed and wound preferably
immediately behind the spool we place a plate or bracket to carry the different
parts of the mechanism.
On this plate
or bracket we mount a short shaft or spindle provided with a hand
lever or hand wheel by which it can be rotated. This shaft or spindle carries one,
two or more eccentrics, cams or cranks by which the several parts of the mechanism
are operated or set in motion.
On the end of a pivoted lever we secure a cutting device such as a knife or
chisel which is placed over the flange of the spool and by lowering which a nick or
incision can be made therein this lever is pivoted on a stud or pin and connected to
a cam or eccentric on the spindle or shaft by means of suitable connecting strap,
link or rod so that it will receive a quick movement as soon as the spindle begins
to move and then practically remain at rest during the completion of revolution or
movement of the spindle.
The
Beside or at one end of the spool is placed a spindle capable of rotation part of
a revolution. At its top end this spindle carries a projecting finger which can be
moved in a path to and fro over or across the spool. This spindle and finger may
be moved to and fro by a rack and pinion connected to a crank on the driving
spindle. Or by means of a crank on the spindle or other suitable device.
spindle is preferably made in two lengths or otherwise so that the height and
position of the moving finger can be adjusted. This finger may also be bent or
cranked if desired. The object of this finger is to lay hold of the thread and
carry it across the flange of the spool so that it can be taken hold of and carried
into the nick and then cut.
At the end of the spool we provide a reciprocating hook or device to lay hold
of the thread. This hook or device moves to and fro in a slide and engages with
or lays hold of the thread and carries it downwards into the nick cut in the end or
flange of the spool. This hook may be moved to and fro in its slide by means of
a pivoted and slotted lever or by a quadrant actuated by a cam or eccentric on the
driving shaft. The hook may move to and fro in a slide or it may be pivoted and
have an angular movement.

page_text: In conjunction with the hook a knife or blade is provided against which the end
is cut when drawn down after catching in the nick.
The hook or the moving finger may be also provided with a gripper to take
hold of the free end of thread after being cut and hold it until the spool is removed
and replace it to enable the next spool to start winding immediately.

Improvements in spooling Machines.
We JAMES MCILRAITH of 3 Prospect Villas, Blackley, in the County of
Lancaster, Millwright, and WILLIAM AYRTON of Gorebrook Ironworks,
Longsight, Manchester, Machine Maker, 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 said invention relates to improvements in spooling machines particularly
those known as Conant spooling machines such as described in the Specification of
Patent No. 2452 of A.D. 1864 and has for its object the provision of mechanism
for the operations of cutting a nick in the spool, fastening the end of the thread
therein and cutting the end of the thread.
In order that our said invention may be more clearly understood we will describe
the same with reference to the accompanying drawings in which Fig. 1 is a side
elevation. Fig. 2 is a plan of our said invention as applied to one of the spindles
of a Conant spooling machine.
A is the spindle containing a bobbin or spool on which the thread is wound in
the ordinary manner. When full of thread it is necessary to cut a nick in one head
of the bobbin to press the thread therein and to cut it off.
To this end we provide a shaft a with a handle or hand wheel at b by means of
which it can be turned.
Mounted on the shaft a is an excentric e about which takes the forked end of a
bell crank lever d having its fulcrum or centre of oscillation at d.
The short arm of the bell crank lever d carries a knife which on the rotation
of the shaft a through a suitable angie descends and cuts a nick in the head or
flange of the bobbin.
The further rotation of the shaft a raises the knife ².
e¹
Another excentric e on the shaft a provided with an excentric strap el operates a
rack e engaging with a pinion at the lower end of a vertical shaft which
carries at its upper end a finger e. At a certain point in the rotation of the
shaft a the shaft is by the means last described caused to partially rotate where-
upon the finger e sweeps over the bobbin and coming in contact with the as yet
uncut thread brings it under the jaw ƒ.
1
Another excentric f on the shaft a operating in the forked end of the lever "
(oscillating about ') imparts an up and down motion to the bar f³ which carries
the jaw In close juxtaposition to the bar f' is a fixed plate f'. The lower
inner edge of the jaw and the upper edge of the fixed plate f³ are formed as
shears so that on the descent of the jaw f the thread lying under it is pressed
into the nick and then severed by the jaw passing the fixed plate fs. The
spindle is preferably made in two parts one sliding in the other and secured
together by a set screw or the like means so that the height of the finger e* may
be readily varied. In lieu of excentrics forked levers or excentric shafts as shown
cranks and suitable connecting rods may be employed for driving the mechanism
from the shaft a.

page_text: The respective angular positions of the excentrics or cranks on the shaft a must
be set so that the actions of the different parts follow each other in the proper
order and at suitable times as will be well understood.
Instead of turning the shaft a by a handle it may in some cases be operated by
the means shown in dotted lines in Fig. 2. In this case a rack g is provided which
slides to and fro with the appliance which removes the bobbin from the spindle.
The rack g gears into a pinion g¹ on the shaft g. The rotation of the shaft g*
causes the shaft a to rotate by means of the bevel wheels g³ g*.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a spooling machine the combination of parts for nicking the bobbin head
pressing the thread over and into the nick and severing the thread substantially as
set forth and shown.
2. In a spooling machine the combination of the nicker d' the finger the
jaw actuated and operating substantially as and for the purpose set forth
and shown.
