IN PIPE JOINTS."
"IMPROVEMENTS.
This Invention consists in a new or improved mode of joining sheet metal pipes.
Instead of providing the contiguous ends of the two pipes with flanges or screw
joints as is usually done, I leave the end of one pipe plain, and form around the
end of the other pipe a socket by taking a ring of sheet metal having a somewhat
larger diameter than the outer diameter of the pipe, and pass it over the end of the
pipe, so that the ring is concentric with the pipe and flush with it at one end.
The other end of the ring is then soldered to the pipe, so as to close one end of the
angular space left between the tube and the ring, for which purpose the corre-
sponding end of the ring may have been bent inward. The end of the other (plain)
pipe is then introduced into the socket formed by the ring and the pipes joined
together. The radial width of the socket is only about large enough to permit the
introduction of the plain pipe, and the depth of the socket is preferably made a
little less than the diameter of the pipe.

"IMPROVEMENTS
This Invention consists in a new or improved mode of joining sheet metal-pipes.
-Instead of providing the contiguous ends of the two pipes with flanges or screw-
joints as is usually done, I leave the end of one pipe plain, and form around the
end of the other pipe a socket by taking a ring of sheet metal having a somewhat
larger diameter than the outer diameter of the pipe, and pass it over the end of the
pipe, so that the ring is concentric with the pipe and flush with it at one end.
The other end of the ring is then soldered to the pipe, so as to close one end of the
annular space left between the tube and the ring, for which purpose the corre-
sponding end of the ring may have been bent inward. The end of the other (plain)
pipe is then introduced into the socket formed by the ring and the pipes joined
together. The radial width of the socket is only about large enough to permit the
introduction of the plain pipe, and the depth of the socket is preferably made a
little less than the diameter of the pipe. Sometimes I form the socket of, or with
receptacles for holding sand, cement, or other luting, or rubber packing. The
improved joint may be applied to pipes other than metal. The accompanying
Drawing is intended to illustrate the mode of performing the Invention, Figure 1
being an inside sectional view of the pipe joint, and Figure 2, part elevation and
part section.
A and C are pipes; B, the joint piece. The piece B is soldered
or otherwise secured to. A, as shown; D are luting channels, one or more. may
be used.
I claim the ring piece B, with or without luting receptacles, substantially as
described and illustrated and for the purpose specified.
In witness whereof, I, the said Thomas Lloyd, have hereunto set my hand
and seal, this Tenth day of October, A.D. 1881.
