PROVISIONAL SPECIFICATION.
Improvements in Flexible Pipe-connections.
I, HERMANN VERING, Engineer, residing at No. 9, Bahnstrasse, Hamburg, German
Empire, do hereby declare the nature of this invention to be as follows:-
My invention relates to flexible connections between two metal or other rigid pipes,
the said connections consisting in a hose of leather, india-rubber or other suitable
material, and its object to make such connections more resistant against irregular
strains, to render the pipes capable of being rotated by a force applied to one of
them, and to prevent the connections from being bent to an njurious extent.
For this purpose I combine with the said bose a universal joint, consisting in two
pairs of arms fastened to the respective pipes so as to be directed towards each other,
and in a ring encircling the hose with sufficient play and pivoted at four points to
the said arms. Besides this, each arm of one pipe is connected to the other pipe by
a rope or chain, having such length as to limit the bending of the hose. For
rendering the connections by means of the said ropes or chains elastic, springs,
india-rubber cushions, or other resilient media may be combined therewith.

COMPLETE SPECIFICATION.
Improvements in Flexible Pipe Connections.
I, HERMANN VERING, Engineer, residing at No. 9, Bahnstrasse, Hamburg, German
Empire, 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 :-
--
My invention relates to flexible connections between two metal or other rigid
pipes, the said connections consisting in a hose of leather, india-rubber or other
suitable material, and its object is to make such connections inore resistant against
irregular strains, to render the pipes capable of being rotated by a force applied
to one of them, and to prevent the connections from being bent to an injurious
extent.
For this purpose I combine with the said hose a universal joint, consisting in two
pairs of arms fastened to the respective pipes so as to be directed towards each other,
and in a ring encircling the hose with sufficient play and pivoted at four points to
the said arms. Besides this, each arm of one pipe is connected to the other pipe by
a rope or chain, having such length as to limit the bending of the hose. For pre-
venting shocks from occurring in the said ropes or chains, springs, india-rubber
cushions, or other resilient media may be combined therewith.
In the annexed drawing a pipe-connection carried out according to my invention is
shown in an outside view. a a are the two metal pipes, and 6 is the bose which
unites them. To each pipe are fixed two arms d, and these arms are connected
together by the ring c and four pivots e, so that the arms form with the ring a
universal joint. Each arm d is connected to a lug h on the opposite pipe a by a
rope g and a spring f, the parts g and having together such length as to prevent
the hose from being bent more than is desired.
The pipes provided with the said connections are especially designed to be used
with dredges for the conveyance of the dredged material by means of a current of
water, and in case the pipes are kept floating on water in which there is any wave-
motion, or which is exposed to changing tidal currents.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The combination of two pipes a having each two arms d with pivots e, the
flexible pipe-portion 6 and the ring c, substantially as described.
2. The combination of two pipes a having each two arms d with pivots e, the flexible
pipe-portion b, the ring c and the ropes g, substantially as specified.
3. The combination of two pipes a having each two arms d with pivots e, the
flexible pipe-portion b, the ring c, the ropes g and springs f substantially as set
forth.
