in the County of Kent, for the Invention of "IMPROVEMENTS IN
COMBINING METALS FOR THE BEARINGS AND PACKINGS OF MACHINERY."
Sealed the 23rd March 1853, and dated the 28th January 1853.
PROVISIONAL SPECIFICATION left by the said James Pole Kingston
at the Office of the Commissioners of Patents, with his Petition,
on the 28th January 1853.
I, JAMES POLE KINGSTON, of 5 Lewisham Road, in the County of
Kent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN COMBINING METALS FOR THE BEARINGS AND PACKINGS
OP MACHINERY" to be as follows: -
This Invention consists of combining tin, copper, and mercury;
and using the same as bearings, or linings of bearings, and for
packings of machinery.

Patent, filed by the said James Pole Kingston in the Great
Seal Patent Office on the 28th July 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I
JAMES POLE KINGSTON, of 5 Lewisham Road, in the County of Kent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the twenty-eighth day of January, in
the year of our Lord One thousand eight hundred and fifty-three,
in the sixteenth year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said James Pole
Kingston, Her special licence that I, the said James Pole Kingston,
my executors, administrators, and assigns, or such others as I,
the said James Pole Kingston, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN COM-
BINING METALS FOR THE BEARINGS AND PACKINGS OF MACHINERY," upon the
condition (amongst others) that I, the said James Pole Kingston, by
an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Pole Kingston, do
hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof (that is
to say):
This Invention consists of combining tin, copper,
and mercury,
and using the same as bearings, or linings of bearings, and for
packings of machinery. And in order that my said Invention may

page_text: be more fully understood, and readily carried into effect, I will
proceed to describe the means pursued by me. I melt at the rate of
about 9 lbs. of copper, and then add 24 lbs. of tin; I allow this com-
bination to cool, and again melt it, and then add 108 lbs. of tin, and
when the tin is melted I add 9 lbs. of mercury, and then allow the
whole to cool. I would remark that I do not confine nyself to the
precise quantities of the metals above given, but I believe them
to produce the best compound for the purposes of my Invention.
The compound metal thus produced is to be made into bearings, if
for light machinery, by forming it, when remelted, into moulds of
the proper forms; and when making packings of machinery I run
the melted metal into the spaces to be packed, as has heretofore been
done with other soft metal, taking care that the surfaces, to which
the packing is not desired to adhere, are covered with smoke or other
proper material, as is well understood; and when lining bearings
I first cause the surfaces of the boxes or bearings (where the
lining is to adhere) to be tinned; I then run in the melted metal,
and I use cores and moulds when necessary as has heretofore been
practised.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that
what I claim is, the combining mercury with tin and copper in the
manufacture of bearings and packings for machinery.
In witness whereof, I the said James Pole Kingston, have here-
unto set my hand and scal, this Twenty-eighth day of July,
in the year of our Lord One thousand eight hundred and fifty-
three.
Witness,
S. CARPMAEL.
JAMES POLE KINGSTON. (L.S.)
