With the waste pipes respectively. find the pipes used to discharge the wastewater very often at the transition from the vertical to the underground drainage pipes Constipation instead. These stem from the fact that there is something solid, contaminating from the roof Substances such as hair, feathers, paper, bird droppings, etc., washed into the pipes that get stuck in the bends of the earth and get stuck. Almost regularly freezing takes place at this point in winter, causing the greatest inconvenience and substantial expenses arise. This evil is not controlled by the various in recent times Cities arranged in the Troftoirs mud boxes, one of which is cleaning the importer Elbow is very difficult and sometimes even impossible. For constipation Usually the waste tube in the lower parts must be taken out and removed the line can be removed to a greater or lesser extent, despite what Hooks and bells are inconvenient and can only be done by professionals. When freezing this is impossible at all and has the pipes jumping in the wake. These evils are supposed to be caused by the present The novelty can be eliminated by placing a cast iron or metal one in the bottom of the waste line Closing tube is switched on, which can be opened easily and conveniently by everyone, hold tight and lets you go back to sleep, so that cleaning can be carried out comfortably.

In the accompanying drawing, the innovation is shown by FIG. 1 in a view, FIGS. 2 and 3 in vertical section and by FIGS. 4 and 5 in cross section. The lower pipe section b , which establishes the connection between the bend k and the upper vertical pipe string α, is conical in shape and can be pushed up and down on the pipe string a, which is immovably held by its two bulge extensions ^. This pipe section b has at its upper end a groove b ¹ which extends around the entire pipe and which is accessible from the outside through two grooves b ^1. With its lower end, the pipe section b extends into the; Elbow k into it and an annular extension b ³ prevents too deep penetration into the elbow k. On the lower part of the pipe string a, over which the conical pipe section b is pushed, the two hemispherical extensions a ^{1 are} attached at the appropriate height from the bend k , the distance from one another with that of the two grooves V ^{1 of} the pipe section b .

To clean the waste pipe BEZW. to make the bend, push the pipe section b upwards until the lower edge of the annular channel b ¹ butts against the approaches a}. During this pushing up, these approaches a ^{1 have passed} through the grooves b ² into the channel b ^{l of} the pipe section b . If you now rotate the latter, the same will lay with the upper edge of its channel b ¹ on the approaches a ¹ and thereby the pipe section in

held in the raised position (Fig. 3). This exposes the elbow and is easy to clean .. The waste pipe is closed by turning the pipe section b in the opposite direction and lowering it, the lower part of b entering the bend k. The small opening 0 is used to indicate the blockage of the lower manifold in good time. The cone of the lower closure piece also allows it to be lifted even if the line is already frozen. Patenτ claim: A waste pipe, characterized in that a conical movable pipe section b is inserted between the fixed upper pipe string α and the elbow k , which, when the pipe is closed, enters the elbow k with its lower end, while it is lifted for cleaning the waste pipe and in this raised position after the pipe section with its grooves έ ² pushed over the lugs a ¹ to α and rotated
