In my former Letters Patent and applications for Letters Patent hereinafter
mentioned I have provided for constructing solenoids and magnets as regulating
devices and electrical machinery as well as for the employment in the construction
of Dynamo electric or Electro dynamic machines and the armatures thereof by the
employment of discs rings coils or thin sheets or bars of magnetic material recessed
or otherwise which I coat or cover with insulation and subsequently place or form
the helix thereon by coiling moulding or deposition upon material applied so as to
represent the form desired to be imparted to the helix and in some cases this helix
is mounted formed or supported upon a non magnetic base.
In order to effectually and economically provide for the construction of such
magnets solenoids magnets armatures for machines or helixes circuits as well as
for resistances consisting of a multiple of conductors or lamina pointed or not
or for insulation of conductors or cables of single or compound strands and between
conductors or between a core or support and the conductor.
In the construction of magnets I employ asbestos paint as a coating applied
to the magnetic core ring or coil which is first turned machined or prepared by
moulding other pressure or otherwise so as to be perfectly true whose part will be
adapted to operate in conjunction with any moving part core or armature and the
asbestos paint or coating is then pressed or operated upon by suitably formed
machinery so that the distribution of the material will be evenly and properly
distributed upon the surface to be coated. I then in some cases apply an evenly
distributed coating metallic or carbonaceous or carbonizable material upon the
asbestos base of the special form desired for the helix of the armature solenoid or
magnet or the special form of the coil or resistance or the special arrangement
of the conducting material which I preferably deposit thereon by deposition
electrically or otherwise in the recesses or upon the projections or otherwise or
I coil the ribbons of metal for forming the helix upon the support and in some
cases the ribbons or wires are so treated and passed through a die or mould or
roller operated by machinery which provides for causing an even distribution and
perfect insulation being obtained and the paint can be applied to the wires
mechanical at one or more parts as it is passing through a series of rolls or discs
of different sizes and series of strands may be twisted or coiled and as passing
through the finishing rolls or parts coated and dried and furthermore each layer
can be dried by heat as passing through the rolls or dies at one or more places
by such means a perfect insulation and as near as practicable indestructible can
be obtained.
If it is desired the asbestos paint may be mixed with or covered by material
or compounds which are thoroughly impervious to water so as to be adapted for
submarine or exposed work and to more effectually tie the parts together or such
may be applied only as outer coating.
In the construction of electric machines solenoids and magnets resistances
regulating condensing and induction devices my improvements are especially

In the Specifications of certain of my former Letters Patent hereinafter
mentioned I have provided for constructing solenoids and magneto for employment
in regulating devises and electrical machinery as well as for employment in the
construction of dynamo machines of segments discs rings coils or thin sheets or
bars of magnetic or nonmagnetic material
or otherwise which I wet
or cover with insulation I subsequently place form or secure the helix thereon by
coiling moulding or deposition upon the material so applied so as to represent the
form desired for such conductor or helix or so as to provide for forming the helix
and in some cases this helix is mounted formed or supported upon a non magnetic
base or support which forms the body of the armature or disc ring or section thereof
or such non magnetic base may be supported upon the magnetic ring disc or section
thereof which constitutes the support and magnetic element of the armature or of
the magnet or series of magnets or sections thereof employed in the construction of
the machine.
part or in other words
I employ asbestos paint or asbestos or such like heat resisting material mixed
or compounded with some cementing agent or compound preferably impervious
to moisture in order to effectually and economically provide insulation in the
construction of the magnets armatures or machines or electro magnets and solenoids
generally as well as for assistance coils or resistances consisting of a multiple of
conductors or lamina (pointed or otherwise) or in the application of insulation to
conductors or cable's of having a single
or compound strands and
between conductors or between a core or support and the conductor. In the
construction of magnets I employ Asbestos paint or a compound
asbestos or the equivalent thereof as a coating applied to the magnetic core ring
section or coil. This core ring coil or base is preferably first made perfectly true
by turning or machining or which it may be formed by shaping or moulding
preferably under pressure under such construction the parts are interchangeable
and adapted to be placed in a position relatively to each other so that a moving
part core or armature will be
to operate in conjunction with the fixed
so that the various parts or sections of the
portions or the moveable portions in both will be adapted to each other the asbestos
paint or coating is then applied pressed or operated upon by suitably formed discs
or distributing devices which can be operated by hand or by mechanical means so
that the material asbestos or asbestos mixed with some cementing agent for instance
oxodized oil or gum or marine glue or other suitable agent or compound employed
as the paint or coating will be evenly and properly distributed upon the surface to
be coated. In some cases I subsequently apply an evenly distributed coating of
metallic or carbonaceouse or carbonizable material through the medium of a brush
or otherwise upon the asbestos base or compound of the form desired for the helix
of the armature solenoid or magnet or the special form of the coil or resistance or
the special arrangement of the conducting material which I in some cases deposit
thereon by deposition (electrically or otherwise) in the recesses or upon the
projections or otherwise as I coil the ribbons of metal for forming the helix upon
the support and in some cases in the preparation of the ribbons or wires for the
helix I coat or cover them with the Asbestos paint or compound and pass them so

page_text: prepared through dies moulds rollers or shaping devices operated by machinery so
as to provide for an even distribution of the insulating material I thereby provide
an effective and practically an indestructible insulation the paint or coating can be
applied to the conductor mechanically at one or more places as it is passing through
a series of rolls or shaping devices or dies will perform their respective functions of
distributing evely and compressing the asbestos or asbestos compound upon the
wire ribbon bar or base to be coated and a series of strands insulated or
prepared may be twisted coiled or otherwise placed together and surrounded
embedded and protected by such insulating medium by passing such compound
cable through the finishing rolls or parts Such compound cable or the separate
strands thereof so coated may be subjected to heat during the time of the passage
thereof through the rolls dies or other shaping devices at one or more places-If it
is desired the asbestos or the equivalent thereof may be mixed with or covered
by material or compounds which are thoroughly impervious to moisture (for instance
oxidized oil gutta percha marine glue or other suitable cementing agent) so that
the cable will be adapted for submarine or exposed work. To effectually unite
the inflammable and indestructible base (such as asbestos or the equivalent thereof
of the insulation or instead of making the asbestos or compound insulation
impervious to water through the medium of the ingredients employed in the
compound in the first application to the conductor or base such compounds or
ingredients impervious to moisture may be applied independently or subsequently
as an outer coating or as an addition to the asbestos or equivalent base material
constituting the base or main body of the insulator In the construction of electric
machine solenoids and magnets resistances regulating condensing accumulating
and induction devices my improvements are especially applicable and also for the
various devices and apparatus of the class described in the specifications of my
former Letters Patent N° 85 dated January 6th 1882 N° 700 dated February 13th
