Abstract
A band saw blade guide includes a cylindrical chisel shaped member mounted at an oblique angle to a band saw blade. The blade guide adjusts the angle of the band saw blade by rotation of the guide about its axis. By rotating the guide about its axis, the angle of the chisel point guiding surface is changed thereby changing the angle of the blade. Further the blade may be guided by a single guide forced against one surface of the blade thereby eliminating the need for guides on both sides of the blade.
Claims4
A band saw comprising:
- a blade;
- and a blade guide mechanism for controlling the blade angle, said blade guide mechanism comprising:
- (a) a blade guide member of cylindrical shape with a flat wedge-shaped tip formed at an end, wherein said flat wedge shape tip intersects another wedge surface of the blade guide;
- (b) a blade guide holder with a blade guide groove for receiving said blade guide member, said blade guide member is axially slid and rotated in said blade guide groove with said wedge shape bearing against said blade, said blade guide groove being at an oblique angle to the length direction of said blade,
- (c) means for securing said blade guide member in said blade guide groove,
- whereby said blade guide member is slid against said blade, rotated about a longitudinal axis of the blade guide member and secured in said blade guide groove, thereby the rotation of said blade guide member, adjusts the blade angle with respect to a direction of cut so that the blade is parallel to the direction of cut of said blade.
