Fig. 4 shows the nKxIern motor-driven iniMing machine with the 

 motor mounted in the base and a chain drive enclosed in the housing 

 at the l)ack driving the spintlle. 



At our suggestion, several of the largest manufacturers of screw 

 machines ha\e incorporated screw slotting devices as standard equip- 

 ment for multiple spindle machines. 



We have just recently worked out a ilesign whereby a high speed 

 screw machine, formerly adaptefl to bras.s part.s only, can now have 

 its spindle s[H>ed reduced through change gears so as to make it adapt- 

 able for iron and nickel silver parts, thus providing greater flexibility.
