COMPLETE SPECIFICATION.
A New or Improved Coupling for Tubes or Pipes.
I, JOSEPH JELINEK of Neustadtl in the Austrian Empire, 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 apparatus for coupling together the ends of pipes or
tubes its object being to construct a coupling which can be quickly and simply
connected and disconnected.
A coupling constructed according to this invention consists of two similar halves
one of which is connected to each of the two ends of the pipes or tubes to be
connected.
The accompanying drawings reference to which is hereinafter made illustrate the
construction and application of the improved coupling,
Figure 1 illustrates an elevation of one half of the improved coupling shewn
attached to one end of a tube.
Figure 2 shews the same half coupling in plan.
Figure 3 is a longitudinal section of the two halves of the coupling secured
together.
As illustrated by the drawings each half of the coupling is similar and consists
of a nut or ring C and C' each furnished with hooks or projections 6. These
hooks are preferably three in number and are formed so as to be capable of
engaging with the hooks of the opposing half of the coupling. The nuts C Care
screwed to engage with hollow screws or screwed sleeves B B carried respectively
by the ends of the tubes A A'. The screwed sleeves are furnished with a milled
The
annular edge or with flats for a spanner so that they may be easily turned.
ends of the tubes are preferably provided with packing or joint rings D D¹. As
will be understood the tubes A A' may be the tubes to be connected or they may
have attached to them the ends of flexible hose pipes. To afford a firm grip to the
hose pipe they are formed with projections or recesses to and to as is usual. To
prevent motion of the screwed sleeves B B' along the pipes A A' the ends of the
pipes are flanged as at a a¹ and collars or rings d are provided.
To connect the couplings the hooks b¹¹ are introduced between each other and
are caused to engage by a partial turn.
The screwed sleeves B B' are then turned
and the packing pieces D D' are forced together. Even should one of the packing
pieces be lost the tightness of the joint is not affected as it can be securely made
with one.
As a modification one half of the coupling may have its hooks rigidly secured to
it, the nut C and the sleeve B being dispensed with. In this case the joint would
be made by rotating one screw only.
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. In a coupling for pipes and tubes the combination with each half of the
coupling of a series of hooks or projections adapted to engage with one another by
the rotation of a screw or screws substantially as hereinbefore described and as
illustrated by the accompanying drawings.

page_text: 2. A coupling for pipes or tubes constructed arranged and operated substantially
as hereinbefore described and as illustrated by the accompanying drawings.
