W. EUGEN FISCHER ■ WUPPERTAL-BÄRMEN Sheet 2 to the letter of 22. o _e pt. 1951

According to the invention, depending on the number of branches desired pre-marked, round, oval, slightly out of round, oblong oval (Flat line profile) or similar knock-out andungstoile Provided in the can, in which after breaking out by hand or cutting out with a knife appropriately formed insulating material fences in each case from the canister through the resulting opening can be plugged in to the outside until the Aasctilagrand d of the socket rests on the Bose inner wall. The otutaen is in his The outer diameter is such that it is almost flush with the sheet metal opening concludes. Completely automatically, expresses itself when browsing also some cardboard with sswisches Bosenbleeh and neck and quietly creates the necessary holding tension and sealing in this way The adhesion of the nozzle can be increased by means of elevations or saster in any shape that prevents the ice from slipping back into the can. A further principle consists in the fact that the sheet metal edge of the marking is out of round and the socket is cylindrical, or vice versa design * In addition, the marking in the tin can can be attached to a pp or more places have recesses f, the zmr recording of tenons or squats g of the nozzle serve.

It is 2wec] £ that is, by keeping the well-known markings for junction and switch boxes and by deliberately simple design of the Stut & e & s, a cheap series production possible and, moreover, by the omission of the previously required additional tools, a great and considerable simplification in the preparation of the desired branch. The connection piece c, which is usually round at the conduction point i and on its stop part, can also be designed round only close to its angular edge, while the connecting section K. on the stop strap as well as on its remaining part, be elongated-oval shaped according to the profile of the impregnation or web conduit
