Abstract
A saw table for sheet material includes a platform having an abutment stop along one edge for engaging and locating sheet material supported on the platform. A mast is disposed adjacent to the platform edge for rotation about an axis perpendicular to the platform. A boom extends from the mast over the platform, and has an elongated track perpendicular to the axis of the mast. A carriage is carried by the boom for movement along the track. The carriage is adapted for mounting a saw, such as a circular saw, such that movement of the carriage along the track brings the saw into engagement with sheet material supported on the platform against the abutment stop.
Claims17
A saw table for sheet material, which includes:
- a platform having an abutment stop for engaging and locating sheet material supported on said platform,
- a mast disposed adjacent to said abutment stop and rotatable about an axis perpendicular to said platform,
- a boom extending from said mast over said platform, said boom having an elongated track perpendicular to said axis,
- a carriage carried by said boom for movement along said track,
- said carriage being for mounting a saw such that movement of said carriage along said track brings the saw into engagement with sheet material on said platform against said abutment stop,
- a lock for locking said mast and said boom at a desired angular orientation with respect to said abutment stop on said platform,
- a support underlying said platform, a first disk secured to said support and a second disk secured to said mast in facing engagement with said first disk, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk,
- said first and second disks having peripheries with indicia for indicating angular orientation of said boom with respect to said abutment stop,
- said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said shank overlying said second disk.

A saw table for sheet material, which includes:
- a platform having an abutment stop along one edge for engaging and locating sheet material supported by said platform, an opposing edge of said platform being free of obstruction such that the sheet stock may be placed on said platform from a direction perpendicular to said abutment stop,
- a mast disposed adjacent to said one edge external to said abutment stop and rotatable about an axis perpendicular to said platform,
- indicia for indicating angular orientation of said mast about said axis,
- a lock for locking said mast at a desired angular orientation about said axis,
- a boom cantilevered from said mast over said platform, said boom having an elongated track perpendicular to said axis,
- a carriage carried by said boom for movement along said track,
- said carriage being for mounting a circular saw such that movement of said carriage along said track brings the saw into engagement with sheet material on said platform, and
- a support underlying said platform, a first disk secured to said support and a second disk secured to said mast in facing engagement with said first disk, said indicia being disposed on said first and second disks, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk,
- said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said threaded shank overlying said second disk.

Apparatus for mounting to a platform to form a saw table, which includes:
- a mast for mounting adjacent to the platform for rotation about an axis perpendicular to the platform,
- a boom extending from said mast for positioning over the platform, said boom having an elongated track perpendicular to said axis,
- a carriage carried by said boom for movement along said track, and for mounting a saw such that movement of said carriage along said track brings the saw into engagement with sheet material on the platform,
- a lock for locking said mast and said boom at a desired angular orientation with respect to said axis, and
- a support for underlying the platform, a first disk secured to said support and a second disk secured to said mast for facing engagement with said first disk, said lock selectively permitting rotation of said mast and said second disk with respect to said support and said first disk,
- said first and second disks have peripheries with indicia for indicating angular orientation of said boom about said axis,
- said lock being a cam lock that includes a cam arm releasably engaging an underside of said support, a threaded shank extending from said cam arm through apertures in said disks, and a nut secured to said shank overlying said second disk.
