Abstract

22,042. Tinsley, J. Oct. 10. Undercutting &c.-The tool-holders for cutterwheel machines for coal consist of boxes B made solid with the wheel or permanently attached to lugs thereon by a pin G. The tools C are secured so that they can be changed to cut in either direction by a wedge-block D, screw E, and nut E<3>. The wedge-block is in halves to fit between the flange and head of the screw, and the nut is held in the shouldered recess B<1>, into which it may be inserted through a side opening or before the box is attached.
