Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Das Wesentliche dieser Construction besteht in beiden Fällen darin, dafs über dem rotirenden Werkzeug ein Schutzdach von passender Form sich befindet, welches an verticalen Schraubenspindeln verstellbar aufgehängt ist. In den Zeichnungen ist das Schutzdach mit A und die Spindeln mit ί bezeichnet. .S zeigt bei der Schutzvorrichtung für Hobelmaschinen die Spindelconstruction in gröfserem Mafsstabe. Die Flügelmuttern in, welche die Spindeln hochziehen, sind auf der unteren Fläche mit einer Nase versehen, welche in einen Einschnitt des Führungsbügels B greift. Die Spiralfedern f dienen dazu, die unteren Flächen der Muttern m immer auf die Fläche der Bügel zu ziehen; sie halten die Nasen der Muttern mit den Einschnitten der Bügel im Eingriff und gestatten trotzdem ein Drehen der Muttern.·The essence of this construction consists in both cases in the fact that over the rotating tool there is a protective canopy of suitable shape, which is adjustably suspended on vertical screw spindles. In the drawings, the canopy is designated with A and the spindles with ί. .S shows the spindle construction of the protective device for planing machines on a larger scale. The wing nuts in FIG. 4, which pull up the spindles, are provided with a nose on the lower surface which engages in an incision in the guide bracket B. The spiral springs f are used to always pull the lower surfaces of the nuts m onto the surface of the bracket; they hold the lugs of the nuts in engagement with the incisions in the brackets and still allow the nuts to be turned.
Bei der Schutzvorrichtung für Holz-Hobelmaschinen wird das flache Schutzdach A so hoch gestellt, dafs das zu bearbeitende Stück Holz gerade in dem Zwischenraum von A und dem Tisch T Platz hat. Der Arbeiter, welcher die Maschine bedient, ist also gezwungen, an der gefährlichen Stelle, d. i. über den rotirenden Hobelmessern, das Holzstück loszulassen, und kann die Hand erst hinter dem Schutzdach wieder darauf legen. Hat man hohe Arbeitsstücke zu hobeln, die nicht die ganze Breite des Tisches bedecken, so wäre zu befürchten, dafs der Arbeiter neben dem Arbeitsstück mit der Hand in die Messer kommt, und es sind deshalb am Schutzdach A die Klappen k angebracht, welche je nach der Breite des Arbeitsstückes in gewisser Anzahl niedergelassen werden können. Es ist endlich vorgesehen worden, dafs für Ausnahmefälle, wo sehr hohe Sachen behobelt werden sollen, das Schutzdach ganz entfernt werden kann; man braucht zu diesem Ende nur die Muttern ^z1 zu entfernen und kann dann das mit dem Vorsprung Z in den gegenüberliegenden Schraubenkloben hängende Schutzdach fortnehmen.In the case of the protective device for wood planing machines, the flat protective roof A is placed so high that the piece of wood to be worked on has space in the space between A and the table T. The worker who operates the machine is therefore forced to let go of the piece of wood at the dangerous point, i.e. above the rotating planer knives, and can only put his hand on it again behind the protective roof. If one has to plan high workpieces that do not cover the entire width of the table, it is to be feared that the worker next to the workpiece will get his hand into the knife, and therefore the flaps k are attached to the protective roof A , which depending on the the width of the work piece can be settled in a certain number. It has finally been provided that in exceptional cases where very tall things are to be planed, the protective roof can be completely removed; you only need to remove the nuts ^ z 1 to this end and you can then remove the protective roof hanging with the projection Z in the opposite screw clamp.
Zu der Schutzvorrichtung für Kreissägen ist noch zu bemerken, dafs die Rollen r dazu dienen sollen, das Brett niederzudrücken, und da die anderen Rollen mit Zähnen und Sperrkegel versehen sind, wird durch diese Einrichtung auch gleichzeitig das Zurückschlagen der Bretter verhütet. Das Dach A ist bei Kreissägen durchbrochen, damit man den Schnitt der Säge ungehindert beobachten kann.Regarding the protective device for circular saws, it should also be noted that the rollers r are intended to push the board down, and since the other rollers are provided with teeth and locking cones, this device also prevents the boards from kicking back. The roof A is perforated on circular saws so that the cut of the saw can be observed unhindered.
