Abstract

The centre drill is an adjunct to the electrically operated potter's wheel. It is possible with its aid to "open" centred lumps of clay, i.e. to drill a wide hole through their exact centre. This makes it possible to turn the said lumps of clay to make pots. This is intended primarily to permit badly disabled people, especially those whose hand movements are limited and those lacking in experience, to achieve a success rate of 100% at the potter's wheel without great effort. Procedure: The centre drill with its two supporting plates (4) is placed on the edge of the potter's wheel (1). The push-button (5) is pressed gently downwards by hand. A metal ring (6) is attached to the bottom of the drill spindle, which metal ring (6) cuts a wide, precisely centred hole into the rotating lump (3) of clay. A bent stay bolt (7) stops the drill from drilling too far into the lump of clay.

Description

Beschreibung der Funktionswiese Description of the function

des Zentrierbohrers Der von mir entwickelte und seit mehreren Jahren im Werkunterricht erprobte Zentrierbohrer dient dem Aufbrechen des zentrierten Tones auf der elektrischen Töpferscheibe. of the center drill The one developed by me and for several years The center drill tried and tested in the workshop is used to break up the centered tone on the electric potter's wheel.

Nachdem ein Tonklumpen auf der Töpferscheibe zentriert ist, stellt man den Zentrierbohrer auf den Gefäßrand der Töpferscheib@. Nun versucht man, das Gestell des Bohrers so zu schieben, daß der ringförmige Bohrkopf in etwa über dem Zentrum der sich drehenden Tonhalbkugel steht. Dann drückt man leicht mit einer Hand auf den Holzknopf und bewegt damit den an seinem anderen Ende befestigten ringförmigen Bohrer in den tonklumpen. nach wenigen Sekunden wird auf diese Weise ein exakt kreisförmiges Loch in den Ton gebohrt.After a lump of clay is centered on the potter's wheel, presents the center drill on the rim of the potter's wheel @. Now you try that Slide frame of the drill so that the ring-shaped drill head is roughly above the The center of the rotating clay hemisphere stands. Then you press lightly with one Hand on the wooden knob and use it to move the ring-shaped knob attached to the other end Drill in the lump of clay. after a few seconds it becomes exactly circular in this way Hole drilled in the clay.

Mit HIlfe eines Stehbolzens kann man genau einstellen, wie tief der Bohrer in die Tonhalbkugel eindringt. Eine Spiralfeder drückt nach dem Bohren die Bohrspindel wieder in die Ausgangslage.With the help of a stud you can adjust exactly how deep the Drill penetrates the clay hemisphere. After drilling, a spiral spring presses the Drill spindle back to the starting position.

In der Regel erfordert das "Aufbrechen" des Tons sehr viel Geschick und Übung. Durch diesen Bohrer allerdings ist es möglich, daß auch handmotorisch behinderte Menschen jeglichen Alters an der T@pferscheibe selbständig arbeiten können.As a rule, "breaking up" the sound requires a great deal of skill and exercise. With this drill, however, it is also possible to use a manual motor disabled people of all ages can work independently at the gate window.
