Manufacturer, for an Invention of "IMPROVEMENTS IN SECURING THE JOINTS
OF EARTHENWARE AND OTHER PIPING AND IN THE APPLIANCES THEREFOR.”
PROVISIONAL SPECIFICATION left by the said James Gooddy at the Office
of the Commissioners of Patents on the 11th July 1881.
"
JAMES GOODDY, of Wombwell, in the County of York, Manufacturer. IMPROVE-
MENTS IN SECURING THE JOINTS OF EARTHENWARE AND OTHER PIPING, AND IN
THE APPLIANCES THEREFOR."
My Invention relates to improvements in the method of securing the joints
of earthenware, metallic, and other pipes, so as to render them water tight, and for
the prevention of leakage. In carrying out my Invention in the joints of earthen-
ware or sanitary piping, for example, I make the opening in the socket end of the
pipe tapering from the mouth inwards till it terminates in a shoulder; I make the
other end of the pipe that is to fit into the socket of the next pipe parallel, and at
a distance from the end corresponding to the depth of the socket, that is, from the
mouth of the socket to the shoulder before mentioned. I form an outside collar
the face of which will abut against the outer face of the socket when the end of
the pipe bears against the inner shoulder of the socket, so that there will be an
open annular space between the parallel end of the pipe, and the tapered inside of
the socket, wide at the top and narrow at the bottom; this space I fill up with a
correspondingly shaped elastic washer (by preference, indiarubber,) so that when
the end of the pipe is pressed home the elastic washer is compressed and effectually
prevents any leakage. The outside collar prevents the elastic washer from escaping
from its compressed position in the socket."
For a further security I form an annular groove in the inside of the socket
somewhere between the mouth and the inner shoulder, in which I place a partly
projecting ring of rubber or other material, so that when the end of the pipe with
its taper washer is forced into the socket of the next pipe, the projecting portion of
the said ring is imbedded by the pressure into the said washer, and additional
security is obtained.

JAMES GOODDY, of Wombwell, in the County of York. "IMPROVEMENTS IN
SECURING THE JOINTS OF EARTHENWARE AND OTHER PIPING, AND IN THE
APPLIANCES THEREFOR."
My Invention relates to improvements in the method of securing the joints of
earthenware, metallic, and other pipes, and more especially the earthenware pipes
used for sanitary purposes, the object being to prevent leakage, and make the
joint flexible to a moderate extent.
In carrying out my Invention in connection with the pipes used for sanitary
purposes, for example, I make the opening in the socket end of the pipe to taper
from the mouth inwards and terminate in a shoulder; I make the other end of the
pipe that is to fit into the socket of the next pipe parallel or taper, but by
preference taper.
The diameter of the end of the pipe is smaller than the diameter of the inside of
the socket, so that when put together there is an open annular space between the
two, larger in 'diameter at the top than at the bottom. Round the inner face of
the socket end I form a groove, the sectional shape being half a circle or there-
abouts, but other shapes may be used if preferred. To fill up the above mentioned
annular space I use a washer or sleeve of india rubber or other elastic or flexible
material, and having a projecting ring or fillet of the same material corresponding
with the before mentioned groove into which it fits, and while effectually preventing
any leakage, it at the same time acts as a key and prevents the washer or sleeve
from altering its position in the socket. As a modification of the before described
arrangement a ring of elastic material may be used separately from the washer or
sleeve, and be placed in the annular groove in the socket, so that the portion which
projects may be imbedded in the elastic washer or sleeve when the end of the pipe
is forced home.
And in order that my Invention may be more fully understood, I will now proceed
to refer to the annexed Sheet of Drawings, premising that the same letters of
reference indicate corresponding parts in all the Figures.
Fig. 1 represents a sectional view of a pipe joint made according to my
Invention. A is the socket tapering down to the shoulder B; C is the annular
groove; D, the tapered end of the pipe; E, the rubber (or other flexible material)
washer or sleeve.
Fig. 2 is a representation of the washer or sleeve; F is the projecting ring or
fillet which fits in the annular groove C.
Fig. 3 represents a sectional view of a modification of my Invention, in which
the ring is made separate from the washer or sleeve.
It will be obvious that the projecting ring on the washer or sleeve will effectually
prevent any displacement of the said washor when in the socket; the joint thus
made will be water tight, and yet will possess a considerable amount of flexibility
sufficient to obviate to a great extent the fracturing of the pipe sockets or joints,
which so frequently occurs in ordinary pipe joints when the ground in which they
are laid subsides.
Having now described and fully ascertained the nature of my said Invention,
and the manner in which the same may be carried into effect, I wish to observe
in conclusion that what I consider to be novel and original, and therefore claim
as the Invention secured to me by the herein before in part recited Letters
Patent is,―
First. The construction of pipe joints with an internal annular groove, and in

page_text: conjunction with an elastic or flexible washer or sleeve having a solid projecting
ring, substantially as hereinbefore described and illustrated.
Second. The use in pipe joints of a washer or sleeve of any suitable elastic or
flexible material provided with one or more projections, preferably in the shape of
a ring, for the purpose as hereinbefore described and illustrated.
In witness whereof, I, the said James Gooddy, have hereunto set my hand
and seal, this Fifth day of January, in the year of our Lord One thousand
eight hundred and eighty two.
