Fig. 7 die Anwendung des Zeichenvorlagenhalters im Zeichenraum.
Der Zeichenvorlagenhalter besteht aus zwei hufeisenförmig gebogenen Hülsen aus Blech b, c, welche an der offenen Schlitzseite d durch das Gleitschiffchen e zusammengehalten werden und die sich übereinanderschieben und etwa bis zur doppelten Länge einer Hülse auseinanderziehen lassen.7 shows the application of the drawing template holder in drawing space.
The drawing template holder consists of two horseshoe-shaped bent sleeves made of sheet metal b, c, which are held together on the open slot side d by the sliding boat e and which can be pushed over one another and pulled apart up to about twice the length of a sleeve.

Am Boden f der Hülse c ist eine dreieckige Stange g drehbar befestigt. Am Deckel h der Hülse b sitzt drehbar eine dreieckige genau auf die Stange g passende Hülse i. Die Stange g und Hülse i schieben sich wie die äußeren Hülsen b, c aufeinander und verbinden so den Boden f mit dem Deckel h, welche außerdem durch eine mit ihren Enden an ihnen angreifende Schraubenfeder ζ zusammengehalten werden. A triangular rod g is rotatably attached to the bottom f of the sleeve c. On the cover h of the sleeve b , a triangular sleeve i that fits exactly onto the rod g is rotatably seated. The rod g and sleeve i slide together like the outer sleeves b, c and thus connect the base f to the cover h, which are also held together by a helical spring ζ that engages them at their ends.

Am unteren Ende der dreieckigen Stange g ist ein Gewinde j eingeschnitten, auf dem mit- , tels einer Mutter 1 und an dieser sitzenden Stifte 2 die untere Kralle k läuft, die in einem Querschlitz I der inneren Hülse c ruht. Ebenso befindet sich am oberen Ende der dreieckigen Hülse i außerhalb des Deckels h ein Gewinde m, ' auf welchem der am Deckel h drehbare Stangen-, halter η mittels Mutter 6 und Stiften 7 läuft.At the lower end of the triangular rod g a thread j is cut, on which, by means of a nut 1 and pins 2 seated on this, the lower claw k runs, which rests in a transverse slot I of the inner sleeve c. There is also a thread m on the upper end of the triangular sleeve i outside the cover h , on which the rod holder η rotatable on the cover h runs by means of nut 6 and pins 7.

Der am Ende der Hülse c sitzende dreieckige Schraubengriff 0 ermöglicht ein leichtes Drehen der Hülse i nebst der Stange g, wobei die Gewinde j, q, m die Muttern 1, 3, 6 gleichzeitig verstellen und damit die Neigung der Krallen k, p und des Stangenhalters η verändern. The triangular screw handle 0 at the end of the sleeve c enables the sleeve i and the rod g to be turned slightly, whereby the threads j, q, m adjust the nuts 1, 3, 6 at the same time and thus the inclination of the claws k, p and des Change rod holder η.

Auf den gefalzten und gezahnten Innenrändern 8 der Außenhülse b läuft das Gleitschiffchen e, welches in einem Querschlitz die bewegliche Kralle p trägt. Dieses Gleitschiffchen e besitzt ebenfalls ein Gewindestück q, das mit ihm lose auf der Hülse i gleitet, aber vermöge der dreieckigen Form der Hülse i gedreht werden kann. Auf diesem Gewindestück q ruht das innere Ende der beweglichen Kralle p auf Stiften 4 einer auf dem Gewindestück q sitzenden Mutter 3. In einer Ausnehmung /im ■ oberen Teile des Gleitschiffchens e liegt der Anker s. Der Anker s hat zwei Aufgaben, er befestigt mittels der Ankerflügel 5, t, welche in die Zahnlücken der Innenränder 8 der Außenhülse b eingreifen können, das Gleitschiffchen e an jeder beliebigen Stelle der Außenhülse b, ferner dringt der Ankerflügel y bei der Schließstellung in die Zugfeder ζ ein und schafft so einen immer der Spannweite entsprechenden Druck. Er besteht aus einem dreistrahligen Stern und hat in der Mitte eine Kreisöffnung,.The sliding shuttle e, which carries the movable claw p in a transverse slot, runs on the folded and toothed inner edges 8 of the outer sleeve b. This sliding boat e also has a threaded piece q, which slides loosely with it on the sleeve i , but can be rotated by virtue of the triangular shape of the sleeve i. On this threaded piece q the inner end of the movable claw p rests on pins 4 of a nut 3 seated on the threaded piece q . The anchor s is located in a recess / in the upper part of the sliding boat e . The anchor s has two tasks the anchor wing 5, t, which can engage in the gaps between the teeth of the inner edges 8 of the outer sleeve b , the sliding boat e at any point on the outer sleeve b, furthermore the anchor wing y penetrates into the tension spring ζ in the closed position and thus always creates a span appropriate pressure. It consists of a three-pointed star and has a circular opening in the middle.

Claims

can therefore not be turned directly through the triangular sleeve *. For this purpose, the threaded piece q located under the anchor s enters, which has one or more notches at the upper end, into which corresponding elevations u of the anchor can engage. When the movable claw p is pressed down a little, it presses the thread q upwards against the ίο anchor s in the slot / tilting, so that the elevations u of the anchor engage in the notches of the threaded piece q. If you now turn the screw handle ο to the right, the armature s rotates by x / 6 circle, you cannot go any further because the armature wing 5 strikes the wall of the sliding boat. During this rotation, the armature wings 5, t release the locking of the sliding boat e by stepping out of the gaps between the teeth of the inner edges 8 of the outer sleeve b, while the long armature wing y releases the tension spring ζ by stepping out of its coils. The sliding boat e is now free and can be moved as desired in the slot d. A x / 6 turn of the screw handle 0 to the left connects it again to the outer large sleeve b. In this direction, too, only 1Z6 rotation is possible, since the anchor wing t now hits the wall of the gliding boat, or because the incision does not go any further. It is therefore only possible to turn x / 6 on both sides, whereby the release and locking of the sliding boat e is achieved. If you let go of the movable claw p, the thread q will turn without the armature s when the screw handle 0 is turned. The anchor s rests firmly and with it the sliding boat e. The model holder rod ν rests in the rod holder η and has an incision 10 at the upper end for attaching templates. When not in use, the rod can be lowered into an opening 11 in the upper cover h. The model board w is a right-angled sheet iron, which is plugged onto the rod ν by means of the holes 12 and adheres to the rod by means of its own tension from the deflection χ. One surface of the model board w is black, the other white. They can both serve as a background as well as a surface by turning the model board over * and thus touching the rod ν. The upper edge of the model board w has two cutouts 13 into which a white or black piece of cardboard can be clamped to increase the background. The use of the drawing template holder is as follows: you support the drawing claw on the table, press lightly on the movable claw p with your left hand and turn the screw handle 0 x / 6 turn to the right with your right hand. The sliding boat e is then going. Then bring it into the required position and turn the screw handle ο ί / β turn back. The sliding boat is then fixed. The claw p is always set to at least 2/3 of the required span of the fixed claw k, never less, as otherwise the tension spring ζ is strained too much. By pulling the claws p, k apart and placing them on the table or bench, the drawing template holder is then attached to the desired location, the tension spring ζ pulling the sleeves b, c and thus the claws p, k against each other and thereby clamping the drawing template holder. If the drawing template holder is to be attached to the front of a school desk that deviates about 30 ° from the vertical, turn the screw handle 0 to the left until the rod holder η and the two claws p, k have reached the required angle of inclination. Here, however, one lets go of the movable claw p. When the handle 0 is turned, the two claws p, k and the model rod holder η move around their support or pivot point at the same time. The claws will always be parallel to each other and the model holder rod ν perpendicular to it. Then pull the claws p, k a little apart and tighten them against the bench by releasing them. Now you slip the model board w over the model rod ν and put both in the rod holder n. The model board w then lies horizontally and is held by the tension of the bend x, whereby gravity supports the clamping of the model board to the rod ν. Godfather nt-A ν saying E:
