The vise has a graduated base that canbe set to any angle, is clamped to the table by four bolts tit-ling in the T slots, and can be used on either the side or topof the table. The rocker arm is designed so that a 3-in. shaftcan 1)0 passed through under the ram for key-seating. Thisshaper is made by the Stockbridge Machine Company ofWorcester, Mass.

The idler is held on thebell crank, as shown, and e-an be raised until the belt makesalmost a complete wrap about the driving pulley. The motoris a Storey 1% h. p., variable speed, and the controller fur-nishes 26 steps by means of field control. As there are tworuns of gearing, the ram has a total of 52 speed changes. The ram is of box pattern, and has a bearing in the column26 ins. long when at full stroke. The stroke can be adjustedfrom the front of the machine, and an index and pointer show-ing length of stroke are in plain view.
