COOPER’S CONDUCTOR OR LEADER PIPE.

The object of this invention is to supply the builder with a conductor-pipe that will not burst after freezing, which all pipes without provision for expansion are liable when water is frozen solid in them. The peculiarity of the joint lies in the wedge principle, applied in a manner which forces the rim of the inside lap hard against the overlapping end with strength sufficient to do without soldering the joints. Besides this, each joint is provided with a fastening which prevents the pipe from settling. This fastening may or may not be used, but if used in connection with the ordinary pipe hook (which does not prevent the pipe from settling) makes a very superior fastening.

The V-shaped corrugation prevents bursting, as it allows the pipe to expand when frozen, thus preventing its bursting. We make two sizes, three and four inches in diameter, twenty-eight inches long, using tin plate, which we galvanize with zinc after it is formed, making a pipe superior to any galvanized iron pipe of equal weight. We make the same not galvanized, but painted one coat inside and out with linseed oil and oxide of iron paint.
