Description:
This type of sander is sometimes called an elbow sander.

"The principle of my invention consists in preparing a revolving disk of wood or metal or other substance in such manner as to revolve by power and so arranged in a frame that is movable on its joints as to be easily brought by the hand of the operator to act on any part of the bench or table on which the work is placed to be polished, the disk or rubber is to be moved while in operation without any interruption of its rotation. This machine is equally applicable to the polishing of doors, tables, or other cabinet work that can be laid upon the bench and also to scouring of leather, by which a great amount of hand labor is saved."
