in the County of Lancaster, Mechanic, in the employ of Messrs.
Butterworth and Brooks, of Sunnyside aforesaid, for the Invention
of "IMPROVEMENTS IN COUPLING PIPES AND OTHER ARTICLES, AND IN
APPARATUS CONNECTED THEREWITH."
Sealed the 7th December 1853, and dated the 1st October 1853..
PROVISIONAL SPECIFICATION left by the said Charles Coates
at the Office of the Commissioners of Patents, with his Petition,
on the 1st October 1853.
1. CHARLES COATES, of Sunnyside, near Rawtenstall, in the County
of Lancaster, Mechanic, in the employ of Messieurs Butterworth &
Brooks, of Sunnyside aforesaid, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN COUPLING PIPES AND OTHER ARTICLES,
AND IN APPARATUS CONNECTED THEREWITH," to be as follows:-
My improvements consist in forming an air, gas, steam, or water tight.
joint between pipes or other articles by introducing a plain cast leaden.
or other suitable metallic ring between the flanges of the pipes or other

page_text: articles to be coupled together, and in bolting the said flanges together
in the ordinary manner. By this means the metallic ring is slightly
compressed, and a perfect joint is effected. The rings are cast in
moulds of metal or other material containing grooves of various sizes
and shapes, into which grooves the molten metal is poured. By this
means several rings are cast at the same time or separately.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Coates in the Great Seal Patent Office
on the 1st April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
CHARLES COATES, of Sunnyside, near Rawtenstall, in the County of
Lancaster, Mechanic, in the employ of Messieurs Butterworth and
Brooks, of Sunnyside aforesaid, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October, in the year
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Ier heirs and successors, give and
grant unto me, the said Charles Coates, Her special licence that
I, the said Charles Coates, my executors, administrators, and assigns,
or such others as I, the said Charles Coates, my executors, admi-
nistrators, 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 COUPLING PIPES AND OTHER ARTICLES, AND IN APPARATUS CONNECTED
THEREWITH, upon the condition (amongst others) that I, the said
Charles Coates, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Charles Coates, do hereby declare
"

page_text: the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):
My Invention consists in placing rings of lead or other suitable
metal of an oval, circular, or angular section between the flanges of
pipes or other articles, and in bolting the said flanges together so as
to compress the metal ring between them, thereby forming an air,
steam, or water tight joint; also in the apparatus for manufacturing
the said rings of lead or other suitable metal. And in order that my
Invention may be fully understood, and readily carried into effect, I
will proceed to describe the means pursued by me, reference being
had to the annexed Drawing, and to the letters and figures marked
thereon.
DESCRIPTION OF THE DRAWING.
Figs 1, 2, 3, and 4, are transverse sections through my improved
rings, which I prefer to make of lead, but which may be made of other
soft metal. Figure 5, is a section through the joint of two pipes. In
this view a ring A, similar to that shewn in Figure 1, is supposed to have
been placed between the flanges B, of the pipes C, which are bolted
together in the usual manner. The tightening up of the bolts D,
compresses the ring A, thereby forcing the metal of which the ring is
composed into the inequalities in the surface of the flanges of the pipes.
I prefer to have these flanges turned, and to fill up the space between
the outer circumference of the joint ring and the circumference of the
flanges with a mixture of paper pulp and size; but in some cases the
flanges may be left unturned, and other materials may be used to fill
up the space between them. Figure 6, represents a modification of my
Invention. In this view a socket joint is effected by the joint ring E.
When the bolts F, are tightened up the nozzle G, which has a shoulder
on it, forces the ring E, against the socket H, thereby compressing the
joint ring E, and making a secure joint. In this case also the space
between the nozzle and socket may be filled up with paper pulp and size.
Figure 7, represents a front view of part of the mould in which the
joint rings are cast; and Figure 8, a section through the complete mould.

page_text: Each half mould is furnished with five or other suitable number of
grooves, the shape of which when the half moulds are put together
forms oval circles into which the molten lead or other suitable metal is
poured. By this means several rings are cast at the same time as the
metal flows from one groove to the other through the channel I. The
plates forming the mould are held together by the centre pin K, and
nut L, and they are steadied by the pins M. The centre pin is rivetted
into one of the plates to facilitate the separating of the plates when the
rings. have been cast. If it should be required to cast a great many
rings at the same time a series of plates can be secured on one centre
pin, and each plate, except the two outermost, must be furnished with.
grooves: on each side.
Having thus described the nature of my Invention, and the manner
of performing the same, I wish it to be understood that I do not limit
myself to the details herein set forth, as the same may be varied without
departing from the peculiar character of my Invention; and I claim
the improved metal joint rings as shewn and described, and the improved
apparatus in which such rings are cast.
In witness whereof, I, the said Charles Coates, have hereunto
set my hand and seal, this Thirtieth day of March, One thou-
sand eight hundred and fifty-four.
