Above Test Made in Machinery Steel—Very Tough—21 Stroke. *Cone tteps are numbered from 1 to 4, 1 being the largest diameter. the machine is running. A pointer on the ram, traveling alongan index, shows the length of stroke as set. The rocker arm isextra heavy and thoroughly braced and gives practically a uni-form rate of speed to the ram for its entire stroke; it also pro-vides an exceedingly quick return. The machine is readily. T\\ EXTV-ONE INCH BACK GEARED CRANK SHAPER. The column is usually deep and wide, tapering slightly towardsthe top. It is strongly braced internally, and is reinforced out-side by a wide, deep rib. An exceptionally long bearing is pro-vided for the ram. The base is deep and strongly ribbed, andis of pan construction to catch oil drippings. The ram is heavyand designed for uniform rigidity throughout the entire length changed from single to back-geared through a convenient, self-locking lever, and has a back-gear ratio of to 1, which withthe large cone pulley, gives it extraordinary power for takingheavy cuts. The head is operative at any angle within an arc of 100 degreesand has a convenient and efficient locking device. The down April, 1909.
