When it is used as a gaining machine, it is worked from the back ; when usedas a tenoning machine, from the front ; when it is being used as a gaining machine, thetenoning part is made idle simply by casting off the belt ; and the same way with thegainer head when the tenoner is in use^ ITie Egan Tenoner Ilachine will make tenons on both ends of a stick at once, besideswhich, instead of making the tenons by the cutter-heads rather too long, and then cuttingthem off to the desiied length, thus leaving a burr or ridge, it first cuts the stick to theproper length, and thus makes and finishes the tenons, leaving them with a smooth endfinish. TENONING MACHINES. 855 In this machine, shown in Pig. 4, there is a bed like an ordinary lathe-bed, and bearingon the left-hand end a fixed, and on the right-hand end a laterally adjustable, housing, eachhousing carrying two pairs of cutters, onparallel horizontal axes which lie in thesame horizo
