Abstract
A vertical band saw is supported forward from a rolling carriage in a cantilever fashion by a pivot which allows inclined as well as vertical cuts to be made in a workpiece. The carriage is supported on V-rollers with vertical axes which travel along rails affixed to a base. The cantilevered saw frame has a drive motor mounted to and solely supported by its lower end, which therefore swings in unison with the saw frame when the cut angle is changed.
Claims1
A cantilevered band saw, said cantilevered band saw comprising
- a base,
- a band saw carriage,
- means for supporting the band saw carriage from the base,
- said means comprising firstly, four horizontally disposed V-groove wheels which are rotatable on vertical axis means carried by the band saw carriage, and, secondly, V-rails on the base which co-act with the V-groove wheels to enable the ban saw carriage to move back and forth,
- a band saw frame,
- said band saw frame having means for supporting a band saw thereon,
- a motor for a band saw which is carried on the band saw frame,
- said motor being mounted on the lower end portion of the band saw frame,
- said band saw frame, together with the band saw supporting means and the motor, being pivotally mounted to the band saw carriage at a location ahead of the band saw carriage in the direction of work,
- said band saw frame being thereby pivotable thru a wide range of movement without interference with the band saw carriage.
