Description: |

This invention relates to that class of machines in which a casting of any desired form is secured upon a movable bed and traversed longitudinally beneath a cutting-tool, the rate of movement toward the tool being limited, as from twelve to twenty feet per minute, according to the hardness of the iron and the endurance of the tool which, operates upon it. There is, however, no necessary limit to the speed of the table and its attached casting in the reverse direction, except the difficulty of arresting the motion of the table at the end of its stroke without injury to the reversing mechanism; and the object of the present invention is to connect a spring or air cushion adjustably to the table, so as to gradually check the motion of the latter before the reversing mechanism is fully actuated. As the reversing mechanism in such machines is usually actuated by a direct connection with the moving table, it is obvious that a diminution in the speed of the table before the reversing mechanism is operated will entirely obviate the difficulty which arises in actuating the table with a quick return motion and operating the reversing mechanism by direct connection thereto.
