PROVISIONAL SPECIFICATION.
A New or Improved Composition for Making Tight Joints and
similar purposes.
I HENRY REDHEAD of 24 Mather Street, Newcastle on Tyne in the County of
Northumberland, Paint Agent do hereby declare the nature of this invention to be as
follows:-
This new or improved composition is intended to be used instead or red or white
lead and similar materials or substances for making tight steam, water, gas, and other
joints of pipes, Cylinders, manhole covers, and the like and any surfaces that require
to be firmly fixed together so as to be waterproof, dustproof or airproof.
The composition consists of Portland, Roman, or similar cement; Venetian red or
brick dust of any kind; boiled linseed oil or cotton seed oil or other vegetable or
animal oil; litharge or other oxyde of lead; and chalk or whitning. All the solids
are ground or reduced to a very fine powder and mixed with the oil. Any kind of
brick may be used for reducing to dust. By altering the quantity of oil, the
consistency of the mixture is regulated to suit various purposes and applications.
The proportions of the ingredients for general use are preferably as follows.

A New or Improved Composition for Making Tight Joints and
similar purposes.
I, HENRY REDHEAD, of 24 Mather Street, Newcastle-on-Tyne, in the County of
Northumberland, Paint Agent, do hereby declare the nature of this invention and

page_text: in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This new or improved composition is intended to be used instead of red or white
lead and similar materials or substances for making tight, steam, water, gas and
other joints of pipes, cylinders, manhole covers, and the like and any surfaces that
require to be firmly fixed together so as to be waterproof, dustproof and air
proof.
Reduced with boiled oil to the consistency of paint it can be used as an anti-
corrosive wash for boiler bottoms, inside furnaces, engine seatings, shaft alleys, inside
and tops of tanks, coal bunkers and inside ship's skin, iron bridge and girder work
and all engineering purposes.
With the addition of poisonous matter it is also suitable for use as an anti-fouling
composition for the immersed portion of the surfaces of ships, boats and the
like.
The composition consists of Portland, Roman, or similar cement, Venetian red or
brick dust of any kind, boiled linseed oil or cotton seed oil or other vegetable or
animal oil, litharge or other oxide of lead, and chalk or whitning. All the solids are
ground or reduced to a very fine powder, and mixed with the oil. Any kind of brick
may be used for reducing to dust. By altering the quantity of oil, the consistency
of the mixture is regulated to suit various purposes and applications.
The proportions of the ingredients for general use are preferably as follows:-
A little variation in the different quantities used in the mixture will not materially
change the character of the resulting compound; I therefore do not confine myself
to the exact proportions above given but may vary them so long as the resulting
compound is not materially different in its general nature and action from the
compound which is the result of the proportions given.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
The composition of matter consisting of cement, boiled oil, Venetian red or brick
dust, litharge or other oxide of lead and chalk or whitning in or substantially in the
proportions hereinbefore described.
