Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . ing bears a cutting-offsaw ; the back one, two sets of cutters, onefor making each side of a tenon. A handwheel at the right of the machine regulatesthe lengthwise distance between the housingsand between their cutter-heads to suit thelength of stock to be worked. Tlie feed isacross the machine, the stock being fed cross-wise, and it is effected by sprocket chainsalong the face of each housing, each chainbearing dogs, the distance between which isadjustable to suit the width of the stock beingtenoned. The material is fed awav from theoperator, and passing under the saws is cut to length; then passing between the back cut-ters, has both sides of both tenons worked on it. Pressure bars over the endless beds, orfeed chains, keep the stock down on the latter while it is being cut by the saws and the cutter bars will hold the stock down, even if one end is thicker than the other. Thefeed, which is automatic in its operation, is driven from a countershaft under the oed, and is. Fig. 4.—The Egan tenoner machine.
