There are four changes of feed. The H. B. Smith Co. Double Hand-tenoning Machme, shown in Fig. 5, has a bed muchlike an ordinary lathe. At one end is a fixed column, bearing upper and lower cutter-headson horizontal axes. At the other end is a sliding column, bearing similar horizontal shaft, running the length of the machine, drives the cross-feed works, whichare endless sprocket chains with projections, carrying the stick—which is presented parallelwith the machine—across it and between the two cutter-heads on each end of the of these cutter-h
