Fig. 1 is a longitudinal section through ^ the hose coupling, Fig. 2 is a cross section through the same along the line ZZ of Fig. 1 .. with the coupling closed, Fig. 3 is a cross section with the coupling released. . ^:

The purpose of the connection is to provide a hose ^ ^; coupling. produce through which hose lengths can be coupled and uncoupled at the moment in a simple and effective manner. The coupling consists of an inner and an outer part; the outer part is provided with a circumferential groove which contains a movable ring and spring-loaded latches which are rotatably attached to the outer part, in order to be able to step into an annular groove in the inner part. These traps are connected by links to the ring of the outer part, so that by turning the ring the traps can be withdrawn and the inner part released. The outward portion of the clutch is Ä-drilled according to two diameters, -the bores _are: α by a conical portion and a shoulder b connected. An _: elastic pack c lies on the: shoulder b. The further part of the outer coupling part A is provided with a ring d which forms part of the coupling; a ring d ¹ is screwed onto the coupling. A groove remains between the two rings d and J ¹ , in which the ring B can be accommodated. ^_::: The on the opposite sides of the part A and opposite. Nuth e ..are; Recesses /. provided, in which the traps gg ^{1 are} rotatably mounted, which are pressed forward by spiral springs h. The movement of each trap is limited to the outside by a link I which is articulated in a recess j of the ring B and is also connected to the free end of the trap. '■ ·

A recess a ^{1 is} provided in one side of part A of the coupling; Between: see the one end wall of the same and a nose b ^{l of} the ring B, which enters this: recess, there is a spiral spring α ² , which as a rule holds the ring in the position shown in: · FIG. 'The ring B has lugs / c, which' lie over the recesses j ^: and serve to take up a pair of pliers or other tools in order to be able to turn the ring. .: ■

The inner part of the coupling is with a. Circumferential groove / to accommodate the trap vs. ¹ / provided. The inner end of part C is provided with an inclined surface m , and the outer end is somewhat weaker in diameter to accommodate the hose ... The free ends of the trap are at the outer edges for the purpose of engaging with the. inclined surface m of part G bevelled so that when part C is inserted into part A , the traps are driven back and enter the groove of the inner dome part. To solve the coupling, the ring B is rotated, which pulls the trap, gg ¹ outwards through the links i. and, the spring, α ² .. is tensioned. ·
