Improved Union for Pipes, Rods, and the like.
We, RICHARD STANGE, of 20 Leipzerstrasse, Pieschen, near Dresden, Saxony, in
the Empire of Germany, Engineer, ALBRECHT KLINKIG, of 3 Blockhausgasse,
Dresden aforesaid, Coppersmith, and GOTTHOLD SCHILLING, of the firmn of Dr. F. Von
Heyden, of Radebeul, near Dresden aforesaid, Attorney do hereby declare the nature
of our said invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of our invention is to effect improvements in the method of joining pipes
by means of an improved union or coupling.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation showing the application of our invention to two pipes about
to be joined. Fig. 2 is an elevation showing the pipes united together. Fig. 3 is an
end view of Fig. 2. Fig. 4 is a plan view of Fig. 2, partly in section, and Figs. 5
and 6 illustrate a method of fitting the pipes with rings or flanges made in two
halves and bolted together.
o and o¹ are two pipes required to be joined. f is a flange formed at the end
of the pipe o after fitting the collar to such pipe, and f¹ is a similar flange
formed at the end of the pipe o¹, after fitting the collar to the pipe o¹. The
collar is formed with trunnions a a, and the collar is formed with similar
trunnions. A washer d made of lead, rubber, or other suitable material is some-
times inserted between the flanges fand, but this washer d may be dispensed with,
and the two flanges may be jamined together to form the joint. is a doubled forked
lever, the two arms of which are furnished with slots or forks & s. The two arms of
the lever are also furnished with trunnions n n. 1 are spring levers, preferably
made of cast steel, and having eyes at each end. One end of each of these levers lis
pivotted to the trunnions, and the other end of each lever is pivotted to the
trunnions n n on the fork h. a is a socket, formed upon the forked lever h, to receive
a rod c (Fig. 1) for convenience in drawing the pipes forcibly together.
The method of using this invention is as follows:-The pipes o o' being placed near
together, as shown in Fig. 1, the lever his raised, and the forks ss are passed over
the trunnions. The lever is then turned downwards, towards or into the
position shown in Fig. 2, whereby the flanges ff' are brought forcibly into contact,
or caused to enclose a washer d. The bar c may then be removed, the joint being
complete. The curved spring levers 7 furnish sufficient elasticity to allow for
expansion and contraction.
For old pipes, or pipes in positions which are difficult of access, we provide
collars (Figs. 5 and 6) made in halves and bolted together upon the pipes, behind
the flanges. The levers are then fitted as above described.
Our invention is applicable to all kinds of pipes, and also to couplings for steam
heating, air, and other pipes on railway carriages, and also for joining together props
or poles in mines, and other analogous purposes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
l
1. The method of uniting pipes and other analogous articles, by means of spring
links or levers in combination with the forked lever and other appliances
severally operating substantially as hereinbefore described and illustrated by the

page_text: 2. The general construction; combination, and arrangement of the several and
respective parts, together constituting our invention of an improved union for pipes
and analogous purposes, substantially as hereinbefore described and illustrated by
the drawings.
