PATENTAMT.PATENT OFFICE.
Die bisher gegen das Verziehen der Reifsbretter angewendeten Hirnleisten, welche vernuthet und verleimt werden, verhindern vollständig die Querschrumpfung und Ausdehnung der einzelnen durch sie zusammengehaltenen Bretter. Infolge dessen reifsen letztere, oder das ganze Reifsbrett wirft sich infolge der ungleich auftretenden Spannung. Giebt aber die Verleimung der Hirnleisten nach, so treten diese bei dem stets am stärksten auftretenden Zusammenschrumpfen der Einzelbretter oben und unten vor und verhindern hierdurch das Anlegen der Reifsschiene.The brain strips previously used against the warping of the frosting boards, which are reasonable and are glued, completely prevent the transverse shrinkage and expansion of the individual boards held together by them. As a result of this, the latter, or the whole frost board throws itself as a result of the unevenly occurring tension. But give them After gluing the head strips, this occurs with the one that always occurs most strongly Shrinkage of the individual boards above and below and thus prevent that Applying the hoop rail.
Allen diesen Uebelständen in vollkommenster Weise abzuhelfen, ist Zweck der vorliegenden Erfindung.To remedy all these evils in the most perfect way is the purpose of the present one Invention.
In der Zeichnung istIn the drawing is
Fig. ι eine' Ansicht des Zeichenbrettes,Fig. Ι a 'view of the drawing board,
Fig. 2 ein Querschnitt desselben,Fig. 2 is a cross section of the same,
Fig..3 ein Längsschnitt nach A-B der Fig. i.Fig..3 is a longitudinal section according to AB of Fig. I.
Die das Verziehen verhindernden Leisten a sind vollkommen eingeschlossen. Sie durchdringen die mittleren Bretter b vollständig und dringen ein genügendes Stück in die Endbretter c ein. Das Einsetzen geschieht lose, also ohne Verleimen, und an den Enden der Leisten α ist ein Spielraum e gelassen,, so dafs durch die Leisten ein Hindernifs für die Querschrumpfung und Ausdehnung der Bretter nicht geschaffen wird.The warp preventing bars a are completely enclosed. They penetrate the middle boards b completely and penetrate the end boards c a sufficient length. The insertion is done loosely, that is, without glueing, and at the ends of the strips α there is a margin e , so that the strips do not create an obstacle to the transverse shrinkage and expansion of the boards.
Die Hirnseiten des .Reifsbrettes werden mit einem das Quellen verhindernden Anstrich versehen.The brains of the tire board are coated with a coating that prevents swelling Mistake.
