CARL ALBERT HIRTH in STUTTGART. Vorrichtung an Reifsbrettern zum Aufspannen des Papiers.CARL ALBERT HIRTH in STUTTGART. Device on hoop boards for stretching the paper.
Patentirt im Deutschen Reiche vom 29. Mai 1880 ab.Patented in the German Empire on May 29, 1880.
Diese Vorrichtung besteht aus einer in die Oberfläche des Reifsbrettes A gefrästen Nuth B,
ferner aus zwei auf dem Grunde der Nuth B sich hinziehenden kleinen Nuthen c und d, aus
den vor Oxydation geschützten Metallschienen E, welche mit einer Anzahl spitzer Zähne ζ versehen
und je nach Bedarf mit einem oder mehreren kleinen Schlitzen m durchbrochen sind,
Fig. 4 und 5, endlich aus den Federn F, Fig. 6 a und 6 b, welche so an den Mittelschienen angebracht
sind, dafs ihre Theile i, Fig. 5 und 6 b, in den Schlitzen m sich bewegen können.
Die Anwendung geschieht folgendermafsen:
An den Schienen E werden die Riegel F zurück und so in die Höhe gezogen, dafs ihre
Theile i nicht mehr durch die Schlitze m gehen. Alsdann sind die Schienen so in Nuth B zu
drücken, dafs die Zähne Z, das im nöthigen Format beschnittene, angefeuchtete Papier durchstechend,
in Nuthe c greifen können, worauf die Federn F hinabgedrückt werden, so dafs sie,
durch die Schlitze m in Nuth d tretend, die Schienen am Herausfallen zu hindern im Staride
sind. This device consists of a groove B milled into the surface of the tire board A , furthermore of two small grooves c and d extending on the bottom of the groove B , of the metal rails E protected from oxidation, which are provided with a number of pointed teeth ζ and each are perforated with one or more small slits m as required, figs. 4 and 5, finally made up of springs F , figs. 6a and 6b, which are attached to the central rails in such a way that their parts i, figs. 5 and 6 b, can move in the slots m.
The application happens as follows:
The bolts F are pulled back on the rails E and so raised that their parts i no longer go through the slots m . Then the splints are to be pressed into groove B in such a way that the teeth Z , piercing the moistened paper trimmed to the required format, can grip into groove c , whereupon the springs F are pressed down so that they, through the slits m, into groove d kicking to prevent the rails from falling out in the Staride.
