WILLIAM BANCROFT ESPEUT of Jamaica West Indies, but at present of
Cambridge Street Hyde Park, in the County of Middlesex " APPARATUS FOR
WINDING COILS OF WIRE UPON THE ARMATURES OF DYNAMO-ELECTRICAL MACHINES
AND FOR LIKE PURPOSES
دو
My Invention has for its principal object to effect by Machinery or apparatus
as hereinafter described the winding of coils of wire upon the armatures of
dynamo-electrical Machines which operation has hitherto been effected by hand.
According to my said Invention there is provided an apparatus consisting of a
reel or revolving winder which is supported and capable of having motion of
rotation imparted to it in any convenient way. The said reel or winder is split or
hinged so that it can be opened and its opened ends are then passed into and
engaged with the armature to be wound after the manner of the engaging of two
links of a chain. The wire to be coiled upon the armature is wound upon this reel
or winder and its free end is passed out beneath or between a friction device and
attached to the armature. On a motion of rotation being given to the reel the said
wire will be unwound from the reel and coiled upon the armature which is fed
round to receive the wires in regularly distributed laps. The reel or winder may
conveniently consist of three main parts one to contain or hold the wire another
to form the journal in which the winder revolves in its bearings the third being a
pulley to receive a driving strap. The friction arrangement may conveniently
consist of a band or ring of india rubber in a groove at the side of the part
containing the wire.
It will be readily seen that the apparatus may be used for any other winding
operation to which it is or may be applicable

Cambridge Street Hyde Park in the County of Middlesex "APPARATUS FOR
WINDING COILS OF WIRE UPON THE ARMATURES OF DYNAMO ELECTRICAL MACHINES
AND FOR LIKE PURPOSES
"
My Invention has for its object to effect improvements in machinery or apparatus
for winding coils of wire upon the armatures of dynamo electrical machines or the
like as hereinafter described
And in order that my said Invention may be fully understood I shall now
proceed particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheet of drawings the same letters of reference
indicating correspondence parts in all the figures.
Figure 1 represents in side elevation and Figure 2 in plan an apparatus
constructed according to my Invention-Figure 3 is a section on the line z z
Figure 1.
The bracket piece A carries a toothed ring B mounted in an annular recess in
the said bracket piece A to retain the said ring B in position in the said bracket
piece A pinion C is carried upon a shaft C and in a recess in the part A so as to
engage with the teeth on the ring B. A reel e is mounted upon an axis carried
by the ring B-A disc of india rubber e² may be placed between the reel and the
ring and by means of the nut e³ the frictional contact of the said reel with the said
ring can be adjusted to give a proper tension of the wire in winding.
This reel e carries the wire to be wound upon the armature the said wire being
led over guide and tension pulleys f which are mounted upon axes also fixed to the
ring B-These axes are preferably of sufficient length (as shown in Figure 2) to
admit of the pulleys f following the movement of the wire as it is unwound from
the reel e-For winding an annular armature the bracket piece A. and the ring B
are made in halves or in parts or are provided with a gap for the insertion of the
armature or the like-In the drawing the bracket piece and ring each have a piece
(at x and x2 respectively) cut out of them the said pieces being carried by face
plates or being provided with wings which are bolted to the bracket piece and
ring respectively By removing the bolts the parts xx² can be removed for the
insertion of the armature or other article to be wound-The armature represented
at g is supported in any convenient manner-The part A is formed in parts bolted
together to admit of the insertion of the ring B.
Figure 4 represents a convenient arrangement for the purpose of winding annular
armatures The bracket piece A is carried at the upper part of the standard M
upon which is also carried an adjustable table N provided with clamps p for
holding the armature g whilst being wound-The wire to be wound upon the said
ȧrmature is led from the reel e over the pulleys ff and its end is connected to the
armature On rotating the ring B by means of the pinion C the wire is wound
upon the armature by being carried there-around, as the said ring revolves. The
pinion C may be rotated from any convenient motor by means of gearing as shewn
in Figure 4 or otherwise.
Figure 5 represents in elevation and Figure 6 is a horizontal section of a portion
of a modified form of machine wherein the wire in place of being held upon a ree!
carried by an axis on the ring is contained on an annular slipping carrier h carried
in an annular recess formed in the ring B-The said ring has affixed thereto a

page_text: bracket in which turn the guide and tension pulleys j. k. around which the
wire is led from the carrier to the armature-A screw pin or pins as at y may be
employed by adjusting which the requisite friction may be put upon the slipping
ring h-In this arrangement I have shewn the ring B as being toothed internally
but both it and the ring shewn in figures 1 to 4 may be toothed externally or
internally as may be most convenient-When toothed internally the pinion C will
of course be situated inside the ring B.
The article being wound may be fed forward if desired automatically or by hand
as required to receive the coils.
In place of there being filling.pieces x, x³, for filling the gaps in the piece A. and
ring B these gaps may be left unfilled if found convenient.
Although I have described the apparatus as being used for winding wire upon
circular armatures yet I wish it to be understood that the machine may be
employed for winding either circular armatures or armatures of other form or for
winding wire or other material upon other articles to which it is or may be
applicable.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the invention secured to me by the hereinbefore in part
recited Letters Patent is-
First Apparatus for winding coils of wire upon the armatures of dynamo-
clectrical machines and for other winding purposes consisting of a circular support
in which revolves a ring constituting or carrying the winder reel or carrier for the
wire the said ring being toothed and driven substantially as hereinbefore described
and illustrated in the accompanying drawings
:
Secondly The arrangement and combination of parts constituting the apparatus
for winding wire upon the armatures of dynamo-electricial machines and for other
winding purposes herein before described with reference to figures 1, 2, 3 and 4 of
the accompanying drawings
Thirdly The arrangement and combination of parts constituting the apparatus
for winding wire upon the armatures of dynamo-electrical machines and for other
winding purposes herein before described with reference to figures 5 and 6 of the
accompanying drawings
In witness whereof I the said William Bancroft Espeut have to this my
Specification set my hand and seal this fourteenth day of February One
thousand eight hundred and eighty three.
