Log sawing attachment for a chain saw

A log sawing attachment for a chain saw comprising

• a pair of clamping means for engaging opposite ends of the cutter bar of a chain saw, each of said clamping means being formed with a pair of locking bars which extend beyond the edges of the cutter bar and saw chain and are adjustably interconnected at their opposite ends outside the chain path permitting the locking bars to be drawn together to clamp the chain saw cutter bar therebetween said locking bars being square tubular members having pressure pads secured thereto intermediate the ends and on opposing surfaces thereof for gripping the chain saw cutter bar therebetween and by means of their thickness to provide clearance for the saw chain between the locking bars,
• a pair of square tubular support posts having corresponding indicia printed thereon each of said posts being secured to one of said clamping means and disposed to project perpendicularly from said cutter bar on the same side thereof,
• a guide frame adjustably mounted by means of clamps on said support posts for guiding the chain saw to cut at a preselected depth in the log being sawed, said guide frame including a pair of square tubular slide members having their bottom surfaces disposed in a plane parallel said cutter bar and which slide along the flat surface being used to guide the chain saw during the saw cut, said slide members being cut from a length of extruded stock material of uniform cross-section and having a slot extending along one side thereof whereby bolt heads may be captured inside thereof and moved to any position therealong, said slide members being interconnected by a pair of spreaders and disposed in parallel relation on opposite sides of the plane formed between said support posts, said spreaders being adjustably clamped to said support posts to permit variable spacing of the guide frame with respect to the chain saw cutter bar,
• an intermediate guide member disposed between said pair of spreaders on said guide frame and adjustably secured at its opposite ends between said slide members.
• a guide fence formed from a pair of strips of material of correspondingly bowed configuration secured to the clamping means disposed at the drive end of the cutter bar, each of said strips being secured to one of said locking bars,
• a chain guard removeably securable to the clamping means disposed closest to the race end of said cutter bar, and
• a handle secured to said guide frame disposed on the race end of the cutter bar, said handle including a structural member which is secured to both said spreaders and a hand grip extends from the end of said structural member disposed proximate the race end of the cutter bar.
