PROVISIONAL SPECIFICATION.
An Improved Metallic Packing and Mode of Applying same.
We CHARLES BILLINGTON Senr., and JOHN NEWTON Longport, Stoke-on-
Trent, Staffs., Brass Founders, and THOMAS HAUGHTON, 110 Cannon Street,
London, Middlesex, Engineer, do hereby declare the nature of this invention to be
as follows:-
This our invention relates to an improved metallic packing for use conjointly
with the plugs, seatings and stuffing boxes of cocks, which are operated by means
of rotary or partial rotary motion communicated to same by any suitable means,
the object of our said invention being the prevention of the escape or leakage of
steam, water or other fluid or liquid when passing into or through such cocks.
To carry our said invention into practice we take a suitable quantity of thin
narrow strips or turnings of any suitable anti-friction metal or metals which we
place or pack into the grooves, seatings or stuffing boxes of such cocks in a manner
similar to that in which fibrous vegetable packing is applied for the purpose named,
and we drive such packing by any suitable means into the grooves, recesses,
seatings or stuffing boxes of such cocks, the plug or plugs of which cocks when
placed or forced into its or their seatings compress the said metallic packing and
reduce the said packing in bulk, so that if forms a mass or ring of narrow metallic
strips or turnings, and by experiment we find that a most suitable alloy for this
specific purpose is composed of 93 parts of tin, 6 parts of copper and one part of
mercury, and also that turnings produced by a metal turning lathe are of a most
suitable form as they are flexible, and easily produced.
Dated this 6th day of October 1892.

COMPLETE SPECIFICATION.
An Improved Metallic Packing and Mode of Applying same.
We, CHARLES BILLINGTON Senr. JOHN NEWTON Longport, Stoke-on-Trent,
Staffordshire, Brass Founders, and THOMAS HAUGHTON 110 Cannon Street,
London, Middlesex Engineer, 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 our invention relates to a metallic packing or packings for use conjointly
with the plugs, seatings and stuffing boxes of metallic cocks which are operated by
means of a rotary or partial rotary motion imparted to such plugs by levers or
other suitable means, the object of our said invention being the prevention of the
escape or leakage of steam, water or other fluid or liquid when passing into or
through such cocks.
In carrying our said invention into practice we take an adequate quantity of
narrow thin strips or turnings of any suitable anti-friction metal, metals or alloy
which when impregnated with a suitable quantity of plumbago or other lubricant
we find it specially adaptable for packing such cocks, as such metallic strips
withstand heat, and abrasion by attrition more advantageously than any fibrous
material that is ordinarily used for that purpose. The said metallic strips we place
or pack by any suitable means into the grooves, recesses, seatings or stuffing-boxes
formed in or around the plugs of such cocks, in a similar manner to that in which
fibrous vegetable packing is applied for the purpose named, the plug or plugs of

page_text: such cocks when placed in and forced into its or their seatings compress the said
metallic strips or turnings and reduce the bulk of the said packing so that it forms
a compact mass of narrow metallic strips or turnings. By experiment we find that
a most suitable alloy for the packing of such cocks is composed of 93 parts of tin,
6 parts of copper, and one part of mercury and turnings or strips produced
therefrom by a metal turning lathe or other suitable means are of a most suitable
form and nature, as they are flexible and easily produced.
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 ;-
The application of metallic strips or turnings such as are produced by a lathe, as.
a metallic packing for the grooves, recesses, seatings or stuffing boxes of metallic
cocks which are operated by a rotary or partial rotary motion, for preventing the
escape or leakage of steam, water or other fluid when passing into or through such
cocks as herein substantially described and set forth.
