The lop of the bed is also planed true,bringing the center* always exactly in line with each other. The head-stock is furnished with journal-boxes of extralength lined with genuine babbitt metal, perfectly rigid to re-ceive the large spindle, and on this spindle is a cone pulleywith two speeds and an extra speed to drive the feed, connect-.

The tail-stock is made on an improved plan and is providedwith gears and screws so as to apply the power as near thecenter as it is possible to get, brnging same exactly in line withthe driving center. This tail center revolves in a gun-metaltaper sleeve box. Lost motion can be taken up from time totime so as to enable the operator to run a tight center. Pro-vision is made to withstand the thrust of this center. Both thehead and tail-stock are planed on the bottom so as to bringthem exactly in line with each other. The sliding carriage is made to move back and forth alongthe ways by a screw, operated by a cone pulley and from thefeed-shaft below. Provision is made for opening and closingthe nut automatically for moving the carriage back and is also fitted up with two adjustable arms,
