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.
