The die stock is intended to meet therequirements of a small tool and threadsthe four smallest standard sizes of pipeVi-inch, %-inch, V^inch, ana % removing the chasers from the. Canadian Mach Fig. 1.—Plan of Bottom Cam. stock. The difference between this tooland the larger sizes of the same makeis that in this tool two sets of chasersare used instead of only one set. Thesechasers are operated by a single cam soconstructed as to move one set of chasersback while the other is in use. Eachset is composed of four segments which When the stock is set to thread %-inch pipe the pins on chasers marked Aare in the position shown by arrow (%)in Fig. 1, the pins on chasers marked Bbeing held in the outer part of the slotsas shown by arrow (%). Movement ofthe cam towards the setting necessaryto thread %-inch pipe brings the pins ontlie chasers marked B into the outerslot, thus throwing the chasers clearof the larger size pipe. Further move-ment of the cam plate in this directionmoves the pins in chasers B to the posi-tion shown by arrow while ttiechasers A remain unmoved on accountof the slot at arrow (%) being co
