Improvements in or relating to Apparatus for Laying Wire Rods in
Coils of any required Diameter and Delivering the same after
Coiling.
We, JOHN JAMES BLECKLY and EDWARD BECK, Directors of the Pearson
and Knowles Coal and Iron Company Limited, Warrington, in the County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
Our invention relates to the automatic laying of wire rods, in coils of any
required diameter, as they leave the mill, and to delivering the same ready to be
bundled or otherwise dealt with.
For this purpose we use an S shaped hollow guide pipe, the upper end of which
revolves in a circle represented by its own diameter, and the lower end in a circle
represented by the average diameter of the coil required to be formed. The
upper end of this revolving guide pipe is connected with the finishing rolls of
the mill, by an ordinary bent guide, and the lower end is arranged so as to
revolve in a plane, inclined at an angle to the mill floor and immediately in front
of a sloping plate set in a plane parallel with that in which the end of the pipe
revolves, and so having the same inclination to the floor, the plate is fixed at any
required distance from the lower revolving end of the guide pipe, upon this plate the
rod is laid in a circular form. At the upper edge of the plate and facing the
revolving pipe a flange, in the form of a semi-circle, is fixed of a diameter equal to
the outside diameter of the required coil, and concentric with the circle formed by
the revolving guide pipe, the lower part of the circle, of which the flange forms
one half, is completed by a row of sliding or disappearing pegs, set at a suitable
distance from one another. Inside the circle thus formed, and struck from the
same centre, is an inner circle of similarly sliding pegs, so arranged that the
diameter of the circle they form, is equal to the inside diameter of the coil
required to be made. On the side of the plate, opposite to the revolving pipe,
suitable levers are arranged for actuating both sets of sliding pegs, so as to
withdraw or replace them simultaneously at will.
Having now described the apparatus for effecting our object, we proceed to
describe the process of laying or coiling the rods.
The rod as it leaves the mill rolls is conducted by the ordinary guide into the
laying apparatus and enters the upper end of the revolving guide pipe, the object
of which is, to lay it on the inclined plate in a circular form. The guide pipe is
arranged to revolve, so that the lower end is travelling in a circle, of the average
diameter of the required coil, at a speed corresponding with that at which the rod
itself is travelling through it at the same moment in an opposite direction, and the
effect is, that the rod is laid on the plate in a state of rest, in a circle correspon:ling
to that described by the end of the laying guide pipe, between the inner and outer
circles, formed by the two rows of sliding pege. To prevent the rods overlapping
the pegs, or getting entangled with them, a revolving guard follows the laying
guide and revolves with it.
The rod being now laid evenly on the inclined plate, between the two rows of
sliding pegs, and supported upon them, these are withdrawn by means of levers
behind the plate, actuated either by hand or power, and the finished coil at once
slides down the inclined plate, clear of the machine, onto the floor, or any receptacle
provided to receive it, and is ready for removal by a conveyor or otherwise. By

page_text: reversing the levers, the pegs are at once replaced in position, and the machine is
ready for another rod.

COMPLETE SPECIFICATION.
Improvements in or relating to Apparatus for Laying Wire Rods in
Coils of any required Diameter and Delivering the same after
Coiling.
We,
JOHN JAMES BLECKLY and EDWARD BECK, Directors of the Pearson
and Knowles Coal and Iron Company Limited, Warrington, in the County of
Lancaster, 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 invention relates to the automatic laying of wire rods or similarly flexible
forms of iron or steel in coils of any required diameter as they leave the mill rolls
and delivering the same ready to be bundled or otherwise dealt with.
The invention is best described by aid of the accompanying drawings, in
which :-
Figure 1 is a plan of the apparatus :
Figure 2 is a section of the apparatus when arranged for coiling the wire; and
Figure 3, a similar view of the apparatus when it has just discharged the bundle.
In these, A A are the delivering rolls: B, a wire passing through them: C, spout
delivering the wire from the rolls: D, S-shaped tube or spout receiving the wire
from spout C. This guide pipe D is fixed securely in a revolving hollow shaft E
to which is attached bevel gear F. The axis of pipe D at the upper end coincides
with the axis of the part E, and revolves therewith. The axis of D at its further
extremity revolves in a circle of approximately the diameter of the coil to be
formed. G are a series of stout pins formed in a circle the size of the interior
of the coil to be formed and forming a mandrel or cage for the coil to form on:
H, a second series of stout pins concentric with the last, forming part of a circle
concentric with that of pins G, and of a diameter equal to the exterior of the coil
to be formed, and I, a plate formed in one with the metallic guard J. This plate
is sloping at an angle with the floor sufficiently great to enable the coil of wires to
at once slide off it when free. It is also at right angles to the axis of the revolving
paris E, D and Q, which all revolve together, and also to the pins G and H.
Through this metallic guard J, the pins G and H pass through holes, and they are
attached to the pin plate K; this pin plate has a motion parallel with the axis of
the pins being guided by the block S in slot T. These pins are drawn in and out
of their holes from the position shown in Figure 2 to that in Figure 3 and vice versa
by means of links L and handle M. N is the framework of the machine and O the
bearing of rotating part E carrying the wheel F, pipe D and guard Q. The
guard is to prevent the rod from rising over the pins & and becoming entangled
with them. This and tube D can be formed so as to pass any given distance into
the cage of pins. R is an annular cover plate attached to guard I: it is removed in
Figure 1: S and T, block and slot already mentioned.
The mode of operation is as follows:-
The rod B, as it leaves the mill rolls, is conducted by the guide C into the
layering apparatus and enters the upper end of the revolving guide pipe D, the
object of which is to lay it on the inclined plate J in a circular form. The guide
pipe revolves so that the lower end travels in a circle of the average diameter of
the coil at a speed corresponding to that at which the rod itself is travelling
through it, and the effect is that the rod is laid on the plate in a state of rest, in a
:
f

page_text: circle corresponding to that described by the end of the laying guide pipe between
the inner and outer circles of pins G and H and guard I respectively. To prevent
the rods overlapping the pegs or getting entangled with them, the revolving
guard Q follows the laying guide and revolves with it. The rod being now laid
evenly on the inclined plate J between the two rows of sliding pegs and supported
thereby, the pegs are withdrawn by means of lever M actuated either by hand or
power, the finished coil at once slides down the inclined plate J on to the floor clear
of the machine or into any receptacle provided to receive it, and is ready for
removal by a conveyor or otherwise. By reversing the levers, the pegs are at once
replaced in position and the machine is ready to make a fresh coil.
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 apparatus for laying wire rods in coils, the combination of a revolving
layer, a cage of pins or plates concentric with the axis of the revolving layer, and
means for withdrawing the cage through the floor substantially as described.
2. In apparatus for laying wire rods in coils, the combination of a revolving
delivery, a mandrel or cage round which the coil is wound, and a floor thereof at
an angle with the horizontal through which the mandrel or cage can be withdrawn,
whereby the moment the cage is withdrawn, the coil shoots off by gravity clear of
the machine.
3. The general arrangement and construction of apparatus for laying wire rods
in coils and delivering the same in coils substantially as herein described and
illustrated.
