PROVISIONAL SPECIFICATION.
A New and Improved Material for Packing Pipe Joints, Roofing...
Buildings, and other Purposes.
We, TOM NORMAN of 514, Effingham Road Sheffield, in the County of York,
Engineer, and ELIZABETH COATES of Brunswick Street, Sheffield, aforesaid do
hereby declare the nature of this invention to be as follows:-
This invention is for the manufacture of a new material to be used as a packing for
pipe joints, roofing buildings, and other purposes for which the said material may be
found to be suitable.
In carrying out our invention we propose to take any kind of waste or scrap
leather, such for example, as the waste from manufactories of boots, gloves and other
works where leather is used; we also take the roots and stalks of rushes and prepare
the same by washing and bleaching.
When the whole of these said materials are cleansed from impurities, we place
them in what is known as a beater-engine or pulper in which the materials are
thoroughly reduced to a pulp. We then add to such material an amount of animal
sizing sufficient to enable the material to set, also a proportion of alum.
The materials so prepared and compounded are then passed into what is technically
known as a "
stuff chest" from whence suitable quantities are takon and moulded into
a sheet of any required size and thickness after which it is subjected to hydraulic
pressure.

COMPLETE SPECIFICATION.
A New and Improved Material for Packing Pipe Joints, Roofing
Buildings, and other Purposes.
We, TOM NORMAN of 514 Effingham Road, Sheffield in the County of York,
Engineer, and ELIZABETH COATES of 56, Brunswick Street, Sheffield aforesaid 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 is for a new material or composition for use as a packing for pipe
joints, roofing buildings, and other purposes for which the said material may be
found to be suitable.
In carrying out our invention we propose to take any kind of waste or scrap
leather, such for example, as that made in boot manufactories, glove factories and the
like, we also take the roots and stalks of rushes, and prepare the same by washing
and bleaching.
When these materials as before mentioned are cleansed from impurities, we place
them in what is known as a beater-engine or pulper, by the action of which the said
materials are thoroughly reduced to a pulp.
$
The materials so prepared and compounded are then treated with sufficient animal
sizing and a small proportion of alum, to cause the material to set, and the composition
is then passed into what is technically known in the paper trade as a stuff chest "
from which it is taken in any desired quantity and moulded into sheets of any size
and thickness, and is finally subjected to hydraulic pressure.
The pulp so prepared, may for some purposes, before subjecting it to pressure, be

page_text: laid upon a sheet of canvas, linen or other woven material and pressed into the
interstices of the fibre or meshes so as to form a permanent combination therewith.
Washers or any other form of packings may then be cut from the sheet material, or
it may be used in the sheet for covering steam pipes or for roofing purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
:~
1-As a new material for packing joints, and for other purposes, the combination
of waste leather, prepared rushes, animal sizing and a small proportion of alum, the
said materials being treated and prepared substantially as herein before described.
2-As a new material for packing joints, roofing, and other purposes, the com-
bination of waste leather, prepared rushes, treated with animal sizing and a small
proportion of alum formed into a pulp, and pressed sheetwise upon a sheet of canvas
or other woven material, so as form a permanent combination therewith.
