Zusatz zum Patente M, 82258 vom 10. Juli 1894.Addendum to patent M, 82258 of July 10, 1894.

Patentirt im Deutschen Reiche vom 19. März 1895 ab. Längste Dauer: 9. Juli 1909.Patented in the German Empire on March 19, 1895. Longest duration: July 9, 1909.

Bei der praktischen Ausführung hat sich ergeben, dafs die hervorstehenden Arme e undy der Scheibe d zu vermeiden sind, wodurch erreicht wird, .dafs die Vorrichtung einen kleineren Raum beansprucht und das schlagende Geräusch vermieden wird, welches erstens durch den Anprall des Thüransatzes c gegen den Arm e entsteht, und dann durch das Umschlagen des zweiten Armes f, welches Geräusch um so stärker wird, je schwächer der Anprall der Thür ist und je weniger der Ansatz c zurückgedrängt wird dem Arm f entgegen, so dafs dieser in solchen Fällen aus der Entfernung gegen den Ansatz c schlägt; dann wird durch die Veränderung des Hebels \ ein Abbrechen der Feder h, sowie auch Ueberanstrengen derselben verhindert.In the practical implementation it has been found that the protruding arms e and y of the disc d are to be avoided, whereby it is achieved that the device takes up a smaller space and the knocking noise is avoided, which firstly due to the impact of the door extension c against the Arm e arises, and then by turning over the second arm f, which noise becomes stronger the weaker the impact of the door and the less the extension c is pushed back towards arm f , so that in such cases it is from a distance hits against approach c; then by changing the lever \ a breaking off of the spring h, as well as excessive straining of the same, is prevented.

Nach Wegfall des Armes e wird die Feder g durch folgende Einrichtung über den Todtpunkt gebracht: Unter die Scheibe d ist eine zweite, sich ebenfalls um das Centrum k drehende Scheibe ο gelegt und mit der ersteren fest verbunden. Die letztere 0 ersetzt zugleich die Randerhöhung m der alten Form an der Scheibe d. Sie ist in ihrer Contour aus der Peripherie der Scheibe d schräg ausladend (der die Bufferfeder h tragende Hebel \ ist von seinem beweglichen Punkte aus nach beiden Seiten verlängert; hierdurch strebt sein Druck kreisförmig nach dem Scheibencentrum k). Da die ausladende Contour der Scheibe ο diesen Kreis aber schräg durchschneidet, so gleitet diese (s. Fig. 1 und 2) infolge des durch den Anprall der Thür mit ihrem Ansaz c hervorgerufenen Druckes an dem Hebel \ entlang bis zu dem Absatz p. Dieses Hindernifs in der Contour der Scheibe 0 kann der Druck des Hebels ^ nicht überwinden. Durch die Verschiebung ist die obere Scheibe d so weit gedreht worden, dafs die Feder g dadurch über den Todtpunkt gebracht ist (Fig. 2).After the arm e has been omitted, the spring g is brought to its dead center by the following device: A second disk ο, also rotating around the center k , is placed under the disk d and is firmly connected to the former. The latter 0 also replaces the raised edge m of the old shape on the disk d. Its contour protrudes obliquely from the periphery of the disk d (the lever \ carrying the buffer spring h is extended to both sides from its movable point; hereby its pressure strives circularly towards the disk center k). Since the protruding contour of the disk ο cuts this circle diagonally, it slides (see Fig. 1 and 2) due to the pressure caused by the impact of the door with its point c along the lever \ up to the shoulder p. This obstacle in the contour of the disk 0 cannot be overcome by the pressure of the lever ^. As a result of the displacement, the upper disk d has been rotated so far that the spring g is thereby brought over the dead center (Fig. 2).

Hat die Bufferfeder h dann Ansatz c zurückgeworfen, so drängt die jetzt von der frei gewordenen Feder g weitergedrehte Scheibe d mittelst des Absatzes ρ den Hebel ^ soweit zurück, dafs dieser die im Rückschlag befindliche Thür bis an den Hebel r herandrängt (Fig. 6). In diesem Moment ist der Absatz ρ überwunden und der Hebel ^ findet an der nach der Seite abgeflachten Form der Scheibe 0 keinen Widerstand mehr.If the buffer spring h then threw back approach c , the disc d , which has now been rotated further by the released spring g , pushes the lever ^ back by means of the shoulder ρ to such an extent that it pushes the door, which is in the recoil, up to the lever r (Fig. 6) . At this moment the shoulder ρ has been overcome and the lever ^ no longer finds any resistance on the shape of the disk 0, which is flattened towards the side.

Der zweite Arm f der alten Form wird ersetzt durch einen Hebel r, der auf der Scheibe d beweglich angebracht ist und den ein zweiter Hebel s mit der Zugstange t der Feder g, ebenfalls beweglich, verbindet. Der Stützpunkt des Hebels r ist so angeordnet, dafs mit der ersten Drehung, welche die Scheibe d zu machen hat, der letztere bis in die Bahn A des Thüransatzes c geschoben wird, bei der dann erfolgenden Weiterdrehung der Scheibe d aber gegen den durch oben beschriebenen Vorgang ihm inzwischen entgegengekommenen Thüransatz c seinen ganzenThe second arm f of the old form is replaced by a lever r which is movably mounted on the disk d and which a second lever s connects to the pull rod t of the spring g, also movably. The support point of the lever r is arranged in such a way that with the first rotation which the disc d has to make, the latter is pushed into the path A of the door extension c , but with the further rotation of the disc d against the one described above Process of the door approach which has meanwhile met him c his whole

Claims

Must exert pressure. If the door is opened again, the approach c lifts the lever r and with it the whole mechanism back to its original position. To facilitate this, a roller ν is attached at the appropriate point (FIG. 5), against which the tie rod t is supported during this process. In cases where the impact of the door can be weakened by drafts or other obstacles and is not always strong enough to bring the spring g over the dead center, the embodiment is as follows to facilitate this: The spring h is at the outer end of the lever ■ [attached (Fig. 3, 4, 5 and 6) and rests with its free end on a projection t ■ {present on the disk 0 for this purpose. When the door extension c hits, it then presses the spring h on the one hand on the lever% and on the other hand against the projection t ^, whereby the rotation of the disc 0 is made much easier. In order to make it easier to overcome the obstacle ρ even with such a light impact, the disk 0 on this side has a spring B which pushes itself into a slot in the event of a strong impact, but which does not push the lever, which is only slightly pressed down, into the depth of the Contour slides and thus does not stop further rotation, while under strong pressure this spring B cannot prevent the latter and then acts as a buffer. Furthermore, it has been found necessary in practice to use the spring g, which is resting while the door is open, with its free end to pull the door towards the buffer and thereby turn the whole thing into a door or door. also to make window closers, for which the execution is as follows: The spring g is hung with the free end, otherwise attached to the frame timber, on a lever χ which is movably arranged on the frame timber. On the door there is a second approach w, similar to c. The lever χ is pulled against this by the spring g. When the door is opened, the lever x, pushed back by the extension n>, tensions the spring g strong enough so that it pulls the released door back to the buffer. Pateν τ claims:
