Improvements in Means for connecting Flexible Metal Tube Ends.
I, SALOMON FRANK, of 21, Friedberger, Landstrasse, Frankfurt-on-Main, in the
Empire of Germany, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved method of connecting flexible metal tube
ends. According to this invention the one tube end is widened out slightly, which
is easily effected by screwing thereinto a suitably shaped matrix somewhat larger
in diameter than the inner diameter of the tube end and then after removing the
matrix screwing the threads of the one tube end into those of the other. Or a
flanged tubular piece may be screwed into each of the tube ends to be connected,
the said tubular pieces being provided with external screw threads which in shape
and size correspond to the interior threads of the tube ends to be connected. The
tubular pieces are then connected with one another which may be done by screw
bolts. Or the flanged tubular pieces may be internally screw threaded and be
screwed over the tube ends to be connected.
Dated this 5th day of October 1897.

Improvements in Means for connecting Flexible Metal Tube Ends.
I, SALOMON FRANK, of 21, Friedberger, Landstrasse, Frankfurt-on-Main, in the
Empire of Germany, Mechanical Engineer, 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:-
This invention relates to an improved method of connecting flexible metal tube
ends as hereinafter described. Figure 1 of the accompanying drawing represents
an arrangement according to this invention in which the one tube end (a) is
widened out slightly, which is effected by screwing thereinto a suitably shaped
mandrel somewhat larger in diameter than the inner diameter of the tube end
and then, after removing the mandrel the threads of the tube end (b) are screwed
into those of the other tube end (a).
Another method of connection according to this invention is represented in
Figure 2 wherein a flanged tubular piece c is screwed into each of the tube
ends (a, b) to be connected the said tubular pieces being provided with external
screw threads corresponding in shape and size with the internal threads of the
רנס

page_text: tube ends to be connected. The tubular pieces care then connected with one
another which may be done by screw bolts as shewn.
The method of coupling represented in Figure 3 is the same as that shewn in
Figure 2, except that the flanged tubular pieces c c are internally screw threaded
and are screwed over the tube ends ab to be connected.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
Connecting metal flexible tubes of the character, illustrated by screwing them
into one another or by screwing into or upon them flanged tubular pieces (such
as c) provided with correspondingly shaped external or internal screw threads
connecting the said tubular pieces together.
