The spindleruns in sclf-ccntering bronze boxes ar-ranged so as to compensate for has a dust-proof cap on its front is threaded to take a clutch, and athreaded collar covers the screw v/hennot in use. The spindle is fully back-geared and the gears are protected withguards. The arm is made of steel and is de-signed for horizontal adjustments andhas an arbor support which may beremoved so that any of the attachmentscan be placed in position without thenecessity of removing the arm. l heplaten has an automatic longitudinal andcross-feed in either direction, and is pro-. ^ GEAR FERD PLAIN- MILLING .M.\CHIXE, machine has been made very rigid, be-ing of the box type with telescopic ele-vating screw, and it is heavily supportedby cross girders and with broad bear-iiigs en the face of the column. This tool commends itself to users ofplnin milling machines and attention isc&lled to the positive gear feed driieqnd change-feed mechanism, which i,one of the important features ot thetool. Twenty changes of feel can bemade without stopping th^ is a new clutch ;ni in con-nection with the hand wheels. Thespindle has a No, 10 B, & S, taper holein front end which is made of hammer-ed crucible steel with a 21/32-in. hole vided with three T-slots, the whole isprovided with oil channels and has also a quick return with fine andcoarse hand feed. The makers will behappy to send a circular more fully de-scribing this machine, to anyone
