Improvements in Joint-making Packing.
I, ARTHUR STANLEY MORRISON, of 24, Duke Street, Aldgate, in the City and
County of London, Merchant, do hereby declare the nature of this invention
to be as follows:-
-
This invention relates to an improved joint-making packing which has the
desideratum that it is capable of being used for all purposes and under all
conditions where packing is necessary.
The improved packing is manufactured as follows:-A piece of any suitable
fabric is coated on its side with any suitable lubricating composition. The
fabric is then rolled up with the composition inside until the piece assumes the
form of a cord or band of an approximately round shape in, cross section,
the diameter of which depends on the width of the fabric before it is rolled.
The free edge of the fabric after it is rolled up is temporally fixed by means of
any suitable adhesive such as gold size. It will be understood that I do not
limit myself to the use of any particular fabric or lubricating composition as
any of those now in general use will suffice.
This packing can be almost instantly converted without special knowledge
or skill to suit all the different requirements.
To pack stuffing boxes a piece of the packing of suitable length is cut and
used in the ordinary manner. If the packing is too large it is unrolled and a
piece cut off. If it is too small another piece is unrolled and rolled over the
first piece until the desired size is attained.
To make boiler rings. A piece is cut of sufficient length to make a ring of
the required size allowing enough to overlap to enable a scarf joint to be made
which is held together by being bound round with twine or the like.
To make sheet packing. The material is unrolled and spread out flat and then
folded over on itself or a second piece laid on it, so that the composition lies
between two layers of fabric. The sheet thus made is used in the ordinary
manner.

and ascertained in and by the following statement ; —

Having now particularly described and ascertained the nature of my said

I claim is;-
An engine packing which can be altered quickly and without skill to suit
all requirements for which packing is necessary substantially as set forth in my
specification.
