IMPROVEMENTS IN AND Relating to INSULATORS FOR ANIMAL MAGNETISM
Year: 1881

page_text: LETTERS PATENT to John Lyon, of St. Helen's, in the County of Lancaster,
for an Invention of "IMPROVEMENTS IN AND Relating to INSULATORS FOR
ANIMAL MAGNETISM."
PROVISIONAL SPECIFICATION left by the said John Lyon at the Office of
the Commissioners of Patents on the 30th September 1881.
JOHN LYON, of St. Helen's, in the County of Lancaster.
AND RELATING TO INSULATORS FOR ANIMAL MAGNETISM."
“IMPROVEMENTS IN
This Invention consists in forming insulators of the most perfect resinous kind.
Resinous insulators are too brittle to stand alone, while glass has not sufficient
insulating power. I therefore make the body of the insulator of glass, and
preferably rectangular, with rounded edges so that it may pack easily. On one,
two, or if desirable, threo or more sides of the cube or rectangle I hollow it out so
as more easily to retain the foot of the article it has to support.
In the hollowed side or sides I cut out a dove-tailed or other hole or holes and
fill it or them with resinous non-conductor, such as a mixture of resin and shellac
in equal parts. The side intended to be bottom I sometimes make flat, and also
hollowed out in places, and the hollows filled with the resinous material. I also
frequently coat the entire block with the resinous material.
This Invention can however be widely varied in detail, the main point being to
use glass blocks to stand wear and tear and to protect the resinous material, and
resinous material to complete the isolation. For instance, the article can be glass,
made in two parts with a layer of resinous material sandwiched between the
pieces of glass which are roughened at that point to better hold the resinous
material; other hard and first class non-conductors can be used for the resinous
material above mentioned, but that one is the best and cheapest taken altogether
that I know of.

"IMPROVEMENTS IN
This Invention consists in forming insulators of the most perfect resinous kind.
Resinous insulators are too brittle alone to bear heavy weights or strains, while

page_text: glass has not sufficient insulating power for many purposes. I therefore make the
body of the insulator of glass and in a stationary insulator, preferably rectangular,
with rounded edges so that it may pack casily. Referring to the Drawings, Fig. 1
shows an insulator, and Fig. 2 a castor wheel made according to my Invention
and covered with the resinous material. On one, two, or if desirable three or more
sides of the cube or rectangle I hollow it out so as more easily to retain the foot
of the article it has to support.
When made, as shown in Fig. 1, in the hollowed side or sides of the insulator,
I cut out a dove-tailed or other hole or holes and fill it or them with a resinous
non-conductor, such as a mixture of one of resin and three of shellac in equal parts.
The side intended to be bottom I sometimes make flat, and also hollowed out in
places and the hollows filled with the resinous material; I also frequently coat
the entire block with the resinous material
This Invention can however be widely varied in detail, the main point being to
use glass blocks to stand wear and tear and to protect the resinous material, and
resinous material to complete the isolation. For instance, the article can be of
glass, made in two parts with a layer of resinous material sandwiched between the
pieces of glass which are roughened at that point to better hold the resinous
material
In the case of castors I form the wheel of glass or pottery, and either simply
coat it with the insulating material or form a groove round the periphery with
roughened sides and bottom and run the insulating material into this. My
insulating material is also applicable for many other purposes-where-a-very-high-
degree of insulation is required, as-it-is-very-casy_of_application to even a smooth
hard surface and wears well; indeed in some cases I coat the bed legs only with
the insulating material and can use the castor or glass insulator or not, as desired,
but of course it is preferable to use both the coating and the castor or coated glass
insulator.
Other hard and first class nonconductors can be used for the resinous material
above mentioned, but I prefer that one as the best adapted for the purpose and
cheapest taken all together at present known to me.
Having now described my Invention and the best mode known to me of carrying
it into effect, I wish it to be understood that what I believe to be new and desire
to protect under the liereinbefore in part recited Letters Patent is,—
1st. The combination in one insulator, for the purposes described, of a resinous
nonconducting substance and of a vitreous nonconducting substance, that is, of a
substance that when rubbed would show positive electricity.
2nd. The insulating material consisting of resin and shellac, for the purposes
described.
3rd. The insulators for annual magnetism, constructed substantially as described. 4
In witness whereof, I, the said John Lyon, have hereunto set my hand and
seal, this Twenty ninth day of March, in the year of our Lord One
thousand eight hundred and eighty two.
