Improvements in Metallic Packing.
We, JAMES WARDLE, of 17, Balmoral Terrace, Gosforth, in the County of
Northumberland, Commercial Traveller, ROBERT HANCOCK, Affluk Street, Gates-
head, in the County of Durham, Engineer, and JOSEPH MAUDE, of 12, Harehills
Avenue, Leeds, in the County of York, Bootmaker, do hereby declare the nature
of this invention to be as follows:-
Our invention relates to the application of an alloy in the form of shavings
or turnings to the stuffing boxes of steam, gas, hot air or hydraulic engines,
pumps or the like, which alloy is practically self lubricating.
The alloy consisting of copper, tin and antimony in about the following pro-
portions, which may be varied according to the purpose to which it is to be
applied, viz. tin 100 parts, copper 14 parts and antimony 12 parts may be cast
into round discs and shavings turned off in a lathe of any required thickness or
may be otherwise produced. The mode of application is to pack the shavings
so produced by "stemming them into the stuffing box, around the piston or
other rod to be packed, then inserting the gland and screwing it home, thereby
making a perfectly tight packing yet having a certain degree of elasticity.
"stemmed" in and the
the packing wears against the rod fresh shavings are
gland again screwed home.

Improvements in Metallic Packing.
We, JAMES WARDLE, of 17, Balmoral Terrace, Gosforth, in the County of
Northumberland, Commercial Traveller, ROBERT HANCOCK, of Affleck Street, Gates-
head, in the County of Durham, Engineer, and JOSEPH MAUDE, of 12, Harehills
Avenue, Leeds, in the County of York, Bootmaker, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement: —
Our invention relates to an improved composition and to the mode of applica-
tion of metallic packing for steam, gas, hot air, hydraulic engines and pumps,
or the like, which is practically self-lubricating.
The packing is made from an alloy of copper, tin, and antimony, in about
the following proportions-which may be varied according to the purpose to

page_text: which it is to be applied-tin, say per cwt. 95 parts, copper 10 parts, and anti-
mony 7 parts, cast into round discs or bars from which it may be turned on a
lathe or planed into shavings of any required thickness, or such shavings may
be otherwise produced.

The mode of application is to pack the shavings so prepared either in its loose
state or after the same have been made into coils by "stemming" them into the
stuffing box around the piston or other rod to be packed, then inserting the
'gland" and screwing it home, thereby making a perfectly tight packing, yet
having a certain degree of elasticity. A's the packing wears against the rod
fresh shavings or coils are
65 stemmed" in and the gland" again screwed
home. To bind the packing we may use some fibrous material such as asbestos
fibre, fibrous yarns, or the like, inserted with the shavings or coils, and which
will also serve to absorb the lubricant when required.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, we declare that what' we
claim is: 1
.
FL. It
The manufacture and mode of application of metallic packing, consisting, of
an alloy of tin, copper, and antimony, in approximately the proportions
specified, or in such slightly varied proportions as may be required for special
cases, the alloy being converted into shavings to form coils, and stemmed into
the stuffing box with, in some cases, the addition of asbestos fibre, fibrous yarns,
or like fibrous material to bind the packing; substantially as described.
