The toolcarriage is attached to the front vertical side of the bed, andis guided by square shears. It is secured at the top and bot-tom by removable bearing supports which will permit thecarriaae to be taken from the bed at any part of its length. The carriage is reversed automatically at any desired posi-tion by contact with stops adjustable on the shifter rod. Theoperator can start, stop, or reverse the carriage by manipu-lating this shifter rod by hand. This can l)e done with verjlittle effort on the part of the operator. The main driving gears are enclosed in a \mx, and runpartly submerged in oil. The motor is controlled by a mas-ter switch attached to the shifter rod, and an enclosed panelwith forward, reverse, acceleratint;. and dvnamic brake con-. Niles-Bement-Pond Plate Planer of Improved Design The bearing surfaces are provided with taper gibs for takingup wear. Two relieving tool holder slides are mounted on a stan-dard, and have simultaneous vertical adjustment by meansof a screw and hand wheel, and horizontal adjustment to thestandard through a screw and hand wheel. Both tool slidesare arranged to swivel for planing bevels. The drive screw is supported in a trough with an oil chan-nel of sufficient depth to cover the full depth of the threadwith oil. Roller bearings are provided to take the endthrust of the screw. The pneumatic jacks are of the two-wav type, , air is admitted in the top for clamping theplate. For unclamping, the air is admitted at the bottom. tactor. A push button is mounted on the right hand housing,so that the machine may be started and stopped withoutmanipulating the shifter rod. The cutting speeds range from20 to 40 ft. per min. The housings for the clamp beam overha
