Adjustable band saw driving wheel - has jack-screws to set wheel at angle to vertical to prevent rolling off

摘要

The bandsaw is carried on a wheel (5) which revolves around a horizontal axis. The axis is supported on a sleeve (2) which rides on a vertical post (1). The sleeve may be raised or lowered to control the blade tension. The sleeve is fitted with a number of horizontal jackscrews (10) parallel to the blade wheel axis which enable the wheel to be tilted from the vertical position. The vertical angle of the wheel may also be adjusted by movement of the wheel on its axis.
