Abstract
A clay centering device for a potter's wheel consists of a flat slab mounted on an arm which has at one end a handle and at the other end is releasably engaged rotatably and in universally pivotal manner to a mounting clamp secured to the rim of the tray of the potter's wheel. By means of the handle, the slab may be moved across the potter's wheel, its normally lower edge against the top of the wheel, to contact and center a piece of clay on the revolving wheel. The slab is adjustably fixed on the arm, which is telescopically adjustable.

A clay centering device for a potter's wheel including:
- a elongated arm,
- a centering slab, with a substantially straight normally bottom edge, mounted on the arm,
- a handle at one end of the arm, and
- mounting means attachable to the tray of a potter's wheel,
- said arm being rotatable about its longitudinal axis, and also being universally pivotable within said mounting means, the arm being adapted to be moved by means of the handle to bring the centering slab across the top of the potter's wheel, its bottom edge in contact therewith, to center a piece of clay on the wheel, to be raised and lowered to bring the centering slab above or down to the wheel, and to be twisted about its axis of rotation to vary the angle of inclination of the centering slab to the top of the wheel to shape the clay on the wheel.
