EARS FOR ROLLS ON SHEET BAR AND SLAB=MILLSTEAM FLYING SHEAR TABLE The title plate of Plate XXVI informs us that the viewsshown represent a pair of bevel gears used on a 21-inch sheet barand slab mill steam flying shear table. The bill of material showsthem to be open-hearth steel castings thoroughly annealed. Thefront view of the gears is sectioned by a plane along their axesand shows the gear and the pinion with their teeth engaging, or inmesh as it is called. A pair of bevel gears are usually shown thus,and the reader should make himself familiar with this fact andshould study every detail. The end view of the pinion and theend view of the gear are just sufficiently complete to show thehubs and the holes and key ways through the hubs. A lettered note A states the number of teeth in the pinion,the form of the teeth, the pitch of the teeth, and how they are tobe machined. A lettered note B gives like information for thegear. When reading these lettered notes, the machinist should 52 I. DIA.—^ uin. ; WDIA. ;D. IIOHTFITON 2^ SHAFT\(-ZtBOP£-M
