Improvements in Covering Electrical and other Wires, and Apparatus
therefor.
I, WALTER WILLIAM COLLEY, of 147, Great Saffron Hill, London, Coil Paper
Manufacturer, do hereby declare the nature of my invention to be as follows:-
My invention relates to machinery for winding strips of paper and other mate
rial spirally round wire or conductors.
According to my invention I mount bobbins of paper or other material on a
revolving disc, the wire on which the material is to be spirally laid passing through
the centre of the said revolving disc.
The bobbins of paper or other material that are spirally laid round the wire
are specially cut and reeled with series of layers on each coil so that any desired
quantity of layers of paper can be unreeled from one bobbin and spirally laid
round the wire, one layer upon another in the same order as the material leaves
the bobbin. by this means, by mounting two or three bobbins on a revolving disc,
I can wind round the wire or conductor from twelve to eighteen thicknesses of
material whereas by the present form of machinery 18 different bobbins would
have to be unreeled on a machine to produce the same result.
I am aware of machines that wind paper and other material round conductors
but such material is taken from a roll in single strips. By the action of the disc
revolving, the paper is unwound from the bobbin, passes through suitable tension
bars and guides and is spirally wound round the wire or conductors layer upon
layer in the same order as it leaves the bobbin.
When it is only desirable to wind round the wire or conductor a few layers of
material and only, one bobbin is employed, and revolves round the wire with the
revolving disc. By this means I can obtain a larger roll of material in diameter
to work from. In order to have more than one roll of paper so as to avoid break-
ing the wire I employ an apparatus for rereeling the various layers into rolls the
apparatus consisting of a revolving spindle that the conductor or wire passes
through. A split wooden ring is mounted on the revolving spindle and the end
of the layers of material is taken from series of rolls wound round the wooden
ring and re reeled into one large roll ready for use, when the first bobbin has been
exhausted. By the above means I can cover many miles of wire without a break
in same by following on the re reeled rolls. In order that there should be no
delay in stopping for these rolls. the apparatus is so arranged to rereel at the
same time as the first bobbin is being wound round the wire.

I, WALTER WILLIAM COLLEY, of 147, Great Saffron Hill, London, Coil Paper
Manufacturer, 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 refers to winding strips of paper spirally round wire or other
electric conductors for insulating purposes.
In all machines for this purpose the material has been wound upon the wire in
single layers so that if several layers are required a number of separate rolls of
single strips are separately revolved and their respective ends wound round the
wire, this causes the machinery to be expensive, complicated and the process slow.
By this invention the rolls of paper to be spirally wound round the wire are
cut and reeled in several layers upon the same reel so that several layers can be
wound round the wire together from one and the same roll, this not only reduces
the number of rolls working in a machine but enables the machine to be driven
at a much greater speed, the paper being more easily wound on the wire, and the
breaking of the strips reduced to a minimum owing to the number of layers being
able to withstand the great strain that is necessary to put upon the material in
order that the same may be wound upon the wire in a most perfect manner, this
being a most important feature to ensure a perfect insulation.
Another great advantage in covering the wire from a roll of several layers is
that different kinds of paper can be used. For example where a high voltage is
required the layer that is first wound round the wire may be asbestos paper and the
other layers of strong paper, this in itself is a most important part of the inven-
tion as to apply asbestos from a single layer would be most difficult owing to the
asbestos being so frail, and likely to break by the least strain being put upon it,
whereas if fed with or between other layers of paper the difficulty would be
entirely overcome.
To enable my invention to be properly understood I will proceed to fully
describe the same with aid of the accompanying drawings.
Fig. 1 is a plan of the apparatus. Fig. 2 an end view taken on line X Y. A, a
suitable frame carried by short tubular shafts B B₁ passing through bearings C
so that the frame may be revolved. A third portion of tubular shaft B2 carried
in bearings C is fitted with driving pulleys C to enable the machine to be
operated. Connected to the pulleys is one half of a clutch arrangement D, opera-
ted by a lever E, to engage the other half F of clutch keyed on the shaft B to set
the machine in motion. Carried within the frame A, on short spindles Gare
spools H, upon which the material J, to be wound upon the wire K, is reeled.
These spools. have a necessary degree of breakage or tension imparted to them
by the thunb screws L, and an intermediate elastic washer M, to give the required
tension to the material as it is wound round the wire.
N. adjustable guides to direct the spiral of the winding. One end of these
guides is hinged in the frames, and the angle at which it is desired to be set is
regulated by the screws and nuts P. The wire K is drawn through the machine
from a suitable supply having the necessary tension imparted to it, by the drum Q
operated by the gearing shown at R, R', R2, R3, R4, R, the latter being secured
to the shaft B.
In the accompanying drawings I have shown four spools within the frame A,
but more or less may be employed, but assuming four to be used, and each spool

page_text: wound with four layers of material, this will enable sixteen layers of material to
be spirally wound on a wire, at the same time.
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:
1. The combination of parts forming the machinery for the purpose stated
constructed and operating, as herein before described and illustrated by the accom-
panying drawings.
2. In covering electrical and other wires for insulating purposes with paper
applying the insulating paper to the wire in superposed layers as described.
3. In improvements in covering electrical and other wires for insulating pur-
poses, reeling the paper to cover the wire upon one spool in superposed layers and
winding the layers together upon the wire by revolving the spool round the wire.
4. In apparatus for spirally covering electrical and other wires for insulating
purposes, with superposed layers of paper, the combination with spools cach carry-
ing the paper in superposed layers to be wound upon the wire, carried in a revolv-
ing frame, of guide spindles arranged as shown to regulate the spiral of the
winding.
