Description
Vorrichtung zum Zurechtschneiden von Dachziegeln Die Erfindung betrifft. eine Vorrichtung zum Zureehtsehneiden ( Schroten ) von Dach ziegeln. Bisher wurde hierzu eine Zange ver wendet, die vom Dachdecker beidhändig be dient werden musste, indem je ein Hebel der Zange in eine Hand zu nehmen war. Der Dachdecker hatte also keine Hand frei, um den zurechtzuschneidenden Dachziegel zu halten, was die Arbeit verzögerte. Die Erfin dung behebt. diesen. Nachteil.
Die Vorrichtung nach der Erfindung zeichnet sich dadurch aus, da.ss eine Zange, deren Maul mit ,Schneiden versehen ist, der art auf einem Grundbrett. angebracht ist, dass zum Betätigen der Zange lediglich eineinziger Ilebel zu bedienen ist.. In .der einzigen Figur der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Aufriss dar gestellt.
Die mit geschlossenem Maul gezeichnete Zange 1 ist auf dem Grundbrett 2' befestigt, das unten mit zwei Querdeisten 3 versehen ist, welche dessen Standfestigkeit erhöhen, insbe sondere wenn die Vorrichtung vom Dachdecker auf dem Dache selbst benützt bzw. abgestellt wird. Der untere Teil 4 des Maules ist über den mit ihm aus einem Stück bestehenden Schenkel 5 mittel der Schrauben 6 fest mit dem Grundbrett 2 verbunden. Der obere Teil 7 des lIaules ist über den Kniehebelmechanis- mus 8, 9 mit dem einzigen Bedienungshebel 10 verbunden.
Der Kniehebelmechanismus weist zwei gleiche, abgewinkelte Laschen 8 auf, von denen in der Figur nur die vordere sicht bar ist, welche Laschen. zum Beispiel durch Nieten 11 oder durch Schweissen mit dem obern Maulteil 7 verbunden sind. Diese Laschen sind mit Schraubenbolzen 12 und 13 an den Teilen 5 bzw. 10, angelenkt. Zwei ge rade Laschen 9 sind mit den Schraubenbolzen 14 und 15 an dieseleben Teile 5 bzw. 10 an gelenkt.
Der Abstand zwischen den Bolzen 12 und 13 und derjenige zwischen den Bolzen 14 und 15 sind so gewählt, dass das Zangen maul bei ungefähr horizontaler Lage des He bels 10 geschlossen ist. Die genaue Schliess lage hängt von der Einstellung der Schneid zähne 16 ab, die in Führungen 17 der Maul teile 4 bzw. 7 verstellbar sind und mittels Klemmschrauben 18 fest gehalten werden.
Wenn man den Hebel 10 in Richtung des bei ihm angegebenen Pfeils verschwenkt, so öffnet sich das Zangenmaul, indem die ein zelnen Teile des Kniehebelmechanismus sich in Richtung der entsprechenden Pfeile ver- schwenken. Der Hebel 10 wird bei seiner Auf- und Abbewegung von zwei parallelen Füh- rungsleisten 19 geführt, die durch Schweissen, am Schenkel 5 befestigt sind.
Zwischen den Führungsleisten 19 ist ein Bolzen 2'0 ange- sehweisst, welcher verhindert, dass der Hebel 10 unter die horizontale Lage gedrückt werden kann. Der Hebel 10 kann gegebenenfalls mit einem besonderen, nicht dargestellten Griff versehen sein. Die Schraubenbolzen 12 bis 15 sind so abgesetzt, dass beim Aufschrauben der Muttern die gelenkig zu verbindenden Teile nicht gegeneinander gepresst werden, so dass die Gelenke immer einwandfrei spie len.
Die Einstellbarkeit der ,Schneidezähne 16 gestattet, deren Lage den verschiedenen Dach ziegeldicken anzupassen. Da der Dachdecker nur eine Hand zum Bedienen der Vorrich tung braucht, kann er mit der andern Hand die Ziegel in der richtigen Lage ins Zangen maul halten, wodurch die Arbeit sehr be- schleunigt wird.
Apparatus for Cutting Roof Tiles The invention relates to. a device for cutting (grinding) roof bricks. So far, a pair of pliers was used for this purpose, which the roofer had to use with both hands by taking a lever of the pliers in one hand. The roofer did not have a free hand to hold the roof tile to be cut, which delayed the work. The invention corrects. this. Disadvantage.
The device according to the invention is characterized in that there are pliers, the jaws of which are provided with cutting edges, of the type on a base board. it is appropriate that only a single ilebel is to be used to operate the pliers .. In .der single figure of the drawing, an embodiment of the subject invention is shown in elevation.
The pliers 1 drawn with a closed mouth is attached to the base board 2 ', which is provided below with two transverse ridges 3, which increase its stability, especially when the device is used or parked by the roofer on the roof itself. The lower part 4 of the mouth is firmly connected to the base board 2 by means of the screws 6 via the leg 5 which is made in one piece with it. The upper part 7 of the column is connected to the single operating lever 10 via the toggle lever mechanism 8, 9.
The toggle mechanism has two identical, angled tabs 8, of which only the front is visible in the figure, which tabs. are connected to the upper jaw part 7, for example by riveting 11 or by welding. These brackets are hinged to parts 5 and 10, respectively, with screw bolts 12 and 13. Two straight lugs 9 are hinged with the bolts 14 and 15 on the same parts 5 and 10, respectively.
The distance between the bolts 12 and 13 and that between the bolts 14 and 15 are chosen so that the pliers mouth is closed when the lever 10 is approximately horizontal. The exact closed position depends on the setting of the cutting teeth 16, the parts 4 and 7 are adjustable in guides 17 of the mouth and are held firmly by means of clamping screws 18.
If the lever 10 is pivoted in the direction of the arrow indicated with it, the jaws of the pliers opens in that the individual parts of the toggle lever mechanism pivot in the direction of the corresponding arrows. The lever 10 is guided during its up and down movement by two parallel guide strips 19 which are fastened to the leg 5 by welding.
A bolt 2'0 is welded between the guide strips 19, which prevents the lever 10 from being pushed below the horizontal position. The lever 10 can optionally be provided with a special handle, not shown. The screw bolts 12 to 15 are offset in such a way that when the nuts are screwed on, the parts to be articulated are not pressed against one another, so that the joints always play perfectly.
The adjustability of the cutting teeth 16 allows their position to be adapted to the different roof tile thicknesses. Since the roofer only needs one hand to operate the device, he can use the other hand to hold the tiles in the correct position in the tongs, which speeds up the work.
