To allan/wm it may concern:

Be it known that I, Wmrinm H. Yos-r, a citizen ofl the United States, residing at Montreal, in rthe county of Hochelaga., Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Pipes, of which the following is a specification.

The object of my invention is to provide a structure that will perform the functions both of a pipe and a girder, and for this purpose I construct a pipeof circular or other cross section with interior reinforcing means of the character hereinafter described.

ufacturing such a pipe, and also an article of manufacture.

In the drawings-Figure 1 is a cross sectional view of a strip of metal rolled or the pipe as otherwise formed in such shape as to bel adapted for carryingout my invention. F ig.

2 is a cross sectional .view of a section of pipe embodying my invention.

While there may be some variation in the form of the internal reinforcing means, I have illustrated in the dra a form which I consider well adapted for practical purposes. A strip of metal is formed, preferably by rolling, in the shape illustrated are of slightly greater de th than the re mainng two. When the s ellc ofthe pipe is curved to the form illustrated in Fig. 2, the edges of the projectin ribs a, a abut against each other, and t e edges of the projectin ribs b, b abut against the sides of the ri s a, a at their point of junction. The ed es of the shell c are secured to ether ging, or otherwise, as indicate at d. By means of this construction it will be apparent that I provide means whereby a large body of material is opposed to any strains to which the pipe may be Sub'ected without, however, in any way interfering vthe lshe c 'together..
