Safety attachment for a table saw

An attachment for a table saw having a horizontal table, a blade rotatable in a vertical plane and extending upwardly from the table, and a rip rail upstanding from the table and spaced laterally from the blade to guide a piece of stock into and past the blade as the stock is cut by the blade, said attachment comprising a body adapted to rest slidably on top of the rip rail and adapted to be moved from the front of the rail toward the rear thereof during an active pushing stroke, a pair of laterally spaced legs fixed rigidly to and depending from the trailing end portion of said body and closely straddling said rail to guide said body along said rail during said pushing stroke, the leading side of the lower end portion of one of said legs being positioned to engage the trailing end of said stock at a lateral position between said rail and said blade and to push said stock into said blade during said pushing stroke, a generally U-shaped member formed separately of said legs and having laterally spaced arms, a horizontal pivot connecting said member to said body to enable said arms to swing upwardly and downwardly independently of said legs, said arms closely straddling said rail to stabilize said body relative to the rail during said pushing stroke, the lower end of one of said arms engaging the upper side of said stock at a lateral position between said rail and said blade, and resiliently yieldable means for biasing said arms downwardly about said pivot to cause the lower end of said one arm to press downwardly against said stock and to hold said stock downwardly on said table as said stock is pushed into and past said blade by said one leg.
