Improvements in Sheet Metal Pipes.
We JACOB MYERS FRASHER, Teacher, and JOHN WILLIAM ABRAHAMS,.
Tinsmith, both of Wheeling, County of Ohio, West Virginia, U.S.A., do hereby-
declare the nature of this invention to be as follows:-
The sheet metal pipe of this invention is made in semicylindrical lengths and
the longitudinal edges bent to a hook form. The two hooked edges of one semi--
cylindrical length being engaged by the hooked edges of the opposite section.
The lengths are put together to form a pipe by sliding one length along and into
the other length. The lengths should be put together so as to break joint...
Instead of semicylindrical sections other shapes inay be used.
Dated this 8th day of August 1896.

We, JACOB MYERS FRASHER, Teacher, and JOHN WILLIAM ABRAHAMS,.
Tinsmith, both of Wheeling, County of Ohio, West Virginia, U.S.A., do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following.
statement :-
The sheet metal pipe of this invention is shewn in the accompanying drawing,.
Fig. 1 being an elevation thereof, Fig. 2 an end view on an enlarged scale,.
Fig. 3 an elevation of a bend, and Fig. 4 an end view of a nest of semi sections
of pipe.
a, b, are semicylindrical lengths of sheet metal the longitudinal edges of which
are bent to a hook form as at c, d, to form a slip joint to put the pieces together.
and secure them in place to form a pipe, the section a having its edges outwardly
bent and the section b its edges inwardly bent for this purpose, but the style or
character of the joint may be varied. B is a bend constructed of semicylindrical
sections e, f, the former being shewn in full and the latter in dotted lines.
In putting the sections together they are placed so as to overlap one another or
break joint as shewn, and the pipe completed at each end on opposite sides with a
half length g, the like construction also obtaining in the case of a bend. One end
of each length is crimped as at h to permit it to slip easily under the end of the
length with which it comes in contact.
The lengths or sections a, b, are put together to form a pipe by sliding those of
one side along and into those of the opposite side. Instead of semicylindrical
sections as shewn other shapes may be used such as square, hexagonal or octagonal,
and for the purpose of carriage or shipment the lengths or sections all ready for
putting together may be nested as shewn in Fig. 4.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
A sheet metal pipe constructed of separable and similar semi sections adapted to
be nested for transportation and assembled at the desired place for use, each of
said sections being provided with semi slip joints loosely interlocking to form a
pipe, and the sections assembled to alternate with each other, substantially as
described and shewn.
