KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der vorliegenden Erfindung bildet eine Verbesserung an den durch das Patent 122879 geschützten Verschlüssen für Rohrmündungen.The present invention provides an improvement to the Patent 122879 protected closures for pipe mouths.

Bei der Vorrichtung nach dem Hauptpatente werden die die Bremsbacken tragenden, sowie auch die gegen die \''erschlußplatte sich stützenden Federn von getrennten, entsprechend gebogenen Metallblättern gebildet, während sie im Sinne der vorliegenden Verbesserung aus einem einzigen Metallstreifen in der Weise hergestellt werden, daß die gegen die Verschlußplatte sich stützenden Teile aus der die Bremsbacken tragenden Platte derartig ausgestanzt werden, daß sie an einem Ende mit der vollen Platte zusammenhängen und gegen letztere unter einem spitzen Winkel abgebogen werden.In the device according to the main patent, the brake shoes bearing, as well as the springs supporting themselves against the \ '' locking plate of separate, corresponding curved metal sheets formed while they are in the spirit of the present improvement be made from a single metal strip in such a way that the against the closure plate are supported Parts of the plate carrying the brake shoes are punched out in such a way that they at one end with the full plate and against the latter under one be bent at an acute angle.

In Fig. ι und 2 der beiliegenden Zeichnung ist ein im Sinne der Verbesserung hergestellter Verschluß in einem lotrechten Schnitte und einem wagerechten Schnitte nach A-B der Fig. ι dargestellt.In Fig. 1 and 2 of the accompanying drawings, a closure produced in the sense of the improvement is shown in a vertical section and a horizontal section according to AB in FIG.

Fig. 3 zeigt eine Abänderung.Fig. 3 shows a modification.

Wie in der Einleitung erwähnt, werden die die Bremsbacken g tragenden, sowie die gegen die Verschlußplatte α sich stützenden Federn k aus einer einzigen federnden Platte in der Weise gebildet, daß die Teile k k aus der die Federn dd bildenden Platte derart ausgestanzt werden, daß sie an einem Ende mit der vollen Platte zusammenhängen und gegen letztere unter einem spitzen Winkel abgebogen werden.As mentioned in the introduction, the springs k supporting the brake shoes g and the springs k supporting against the closure plate α are formed from a single resilient plate in such a way that the parts kk are punched out of the plate forming the springs dd in such a way that they are connected at one end to the full plate and are bent towards the latter at an acute angle.

Hierbei können die abdrückenden Teile 3i k k entweder in der Weise ausgestanzt werden, daß sie aus den mittleren (Fig. 1 und 2) oder den seitlichen Teilen (Fig. 3) der die beiden Federn d d bildenden Platte gestanzt werden; im ersteren Falle wird jede der abdrückenden Federn k k von einer einzigen, im letzteren Falle von zwei zu beiden Seiten der unteren Federn d d liegenden Zungen gebildet.Here, the pressing parts 3i kk can either be punched out in such a way that they are punched from the middle (Fig. 1 and 2) or the side parts (Fig. 3) of the plate forming the two springs dd; in the former case each of the forcing springs kk is formed by a single tongue, in the latter case by two tongues lying on either side of the lower springs dd.

In beiden Fällen sind die Bremsbacken g g 4! an den vollen, die Scheitelpunkte der beiden Federn k d bildenden Blechenden angenietet oder geschraubt.In both cases the brake shoes are gg 4! riveted or screwed to the full sheet metal ends forming the vertices of the two springs kd.
