ABSTRACT:
A device for use with an eraser of a rubber composition having magnetic particles dispersed therein. The device has a permanent magnet for attracting the magnetic dust created by use of the eraser. For the ready removal of the collected dust the device further comprises a shield normally enclosing the magnet. When held close to or in direct contact with a dust collecting wall forming a part of the shield, the magnet attracts eraser dust therethrough. The eraser dust attached to the dust collecting wall can be readily released, as into a suitable receptacle such as a trash can, as the magnet is moved away from the dust collecting wall as by being pulled out of the shield. The device may incorporate a magnetic eraser to provide a convenient eraser/dust collector combination, as in some embodiments disclosed herein. Additional embodiments suggest the combined use of a brush for collecting eraser dust, and the provision of an open space for confining the collected dust on the dust collecting wall of the shield.
