PROVISIONAL SPECIFICATION.
Improved Form of Hydraulic and Engine Packing for High and
Low Pressures.
I, JAMES LUVIAN WADE of 62 Nine Elms Lane, Lambeth, in the County of
London, Manufacturing Chemist do hereby declare the nature of this invention to
be as follows:-
My invention consists of a plaited packing composed of the very best fibrous
materials for the purpose viz.: long staple cotton, fine Italian hemp, and asbestos,
or where great elasticity is required I leave out the asbestos or cotton or both.
These yarns are thoroughly incorporated and lubricated with my patent non-com-
bustible and insoluble lubricant before the process of plaiting takes place which
renders it impossible for the packing to become hard in the stuffing box and causes
it to retain its perfect elasticity while its lubricating properties remain unimpaired
to the last. This packing is specially adapted for use in steam engines or pumps
for liquids or gases, the materials of which the packing is composed being varied
to suit the gas or liquid as the case may be. When my improved packing
becomes worn it is only necessary to screw up the gland a little and the packing
being correspondingly tightened is fit for work again. The packing resists all
pressure of air, gas, steam or water, and for its self lubricating and elastic properties
is unrivalled in the market.
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
A combination engine packing, plaited to suit various requirements, highly
lubricated, and capable of withstanding the highest pressures.

I, JAMES LUVIAN WADE of 62 Nine Elms Lane, Lambeth, in the County of
Surrey, Manufacturing Chemist 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 :—
My invention consists of a plaited packing composed of the very best fibrous
materials for the purpose viz.: long staple cotton fine Italian hemp & asbestos or
where great elasticity is required I leave out the asbestos or cotton or both. These
yarns are thoroughly incorporated & lubricated with my patent non-combustible
and insoluble lubricant (Patent 540 %). This is done before the process of plaiting
takes place so as to render it impossible for the packing to become hard in the
stuffing box to cause it to retain its perfect elasticity & to provide for the retention
of its lubricating properties until the fabric perishes. This packing is specially
adapted for use in hydraulic machines, steam engines or pumps for liquids or gases,
the materials of which the packing is composed being varied to suit the gas or
