page_text: New or Improved Insulating Floor Covering.
I, GEORGE EDWARD HEYL-DIA, of 55, Market Street, Manchester, Engineer, do
hereby declare the nature of my said invention to be as follows:-
--
This invention relates to and consists of a new composition or material for uso
in covering the floors of electric transformer chambers, accumulator or secondary
battery rooms, high and low tension central stations and like situations.
According to my invention I employ sheets or layers of paper in its natural
state, or paper treated and impregnated with insulating and water-proofing
substances, such as oils, resins, or pitches, and I combine such paper with layers
of india-rubber or like substances. These layers I then subject to pressure, with,
or without an adhesive medium, in a calendar or press until the several layers are
closely associated. I then remove the composite layers from the press and
vulcanise the whole in the ordinary way, and the resulting article is a floor cover-
ing composed of paper closely sandwiched between layers of rubber and forming
an effective insulation for the purposes aforesaid.
In lieu of india-rubber any india-rubber substitute may be employed, mixed
with cork, barytes, oxide of zinc, French chalk pitch or any similar substances.
Dated this 19th day of December 1899.
