Abstract
A precision saw is the subject of the present invention. A framework mounts a planar member and presents a work surface having an opening for receiving a saw blade. A C-member is coupled with the framework and has upper and lower arms extending parallel to and above and below the work surface. The planar member is mounted for pivotal movement by a pivot rod positioned at a point in a horizontal plane located substantially at the center of the bight of the member. A saw blade extends between the upper and lower arms for cutting a work piece and a drive system is provided for moving the C-member in a generally vertical plane about the single pivot point.
Claims2
A precision saw comprising:
- a framework;
- a pair of spaced apart, substantially parallel mounting plates rigidly connected with said framework and extending therefrom;
- a C-member having generally parallel upper and lower arms and a curved bight connecting said upper and lower arms, said arms and bight being integral;
- an ear integral with said bight and projecting from the concave side thereof, said ear fitting closely between said mounting plates;
- a substantially horizontal pivot pin extending through said ear and mounting plates to mount said C-member for pivotal movement about a horizontal pivot axis defined by said pivot pin;
- a saw blade extending between said upper and lower arms for cutting a work piece;
- power means for driving said C-member in reciprocating motion about said pivot pin to effect movement of the saw blade;
- a table presenting a planar work surface for feeding of the workpiece to the saw blade, said work surface having an opening for receiving the saw blade;
- a cross brace rigidly connected with said mounting plates and extending therebetween;
- means for connecting one end of said table to said cross brace for pivotal movement about a first pivot point;
- a bracket rigidly connected with said framework and extending therefrom, said bracket being spaced from said cross brace;
- and
- means for connecting said table to said bracket for pivotal movement about a second pivot point aligned with said first pivot point to establish a pivot axis about which said table can be tilted.
