The driving worm wheelshave a bronze ring with teeth of steep lead and hardened steel,and the driving worm is of hardened steel fitted with roller thrustbearings, both of which are encased and run in oil. Special pro-visions to prevent the escape of oil are made, the flange beingcast soliil with the saddles, extending 2 in. beyond the bub on. VERTICAL AND HORIZONTAL MILLING MACHINE It will be noted that this machine has about all the featuresthat can be desired for general utility, yet is very flexible in itsoperations, and is therefore adapted to the different classes ofwork in railroad shops on account of the convenient locationand small number of operating levers, and the fact that onetransmission serves for all the moving parts. The machine is alsoso designed that the side head can be placed on either side, theright or left hand upright, or one on each upright, and twoon the cross rail. The diameter of the spindles in the adjustable saddles is 4in.; in the sleeve of the driving worm, 35^ in.; independent handadjustment to spindles, 8 in., and diameter of spindle drivingworm wheel, 19 in. The maximum distance between the up-rights is 45 in.; maximum height under vertical spindle, 25 in.;maximum height center of horizontal spindle to top of thework table, 17 in.; and maximum dis
