摘要： An adjustable tool is disclosed for dispensing a two-part adhesive from a two-chamber cartridge having a mixing nozzle with each chamber having a plunger. Pistons are insertable into the respective chambers. Piston rods and a drive rod move conjointly with the pistons. A lever is pivotable on the frame. A feed nut is mounted loosely on the drive rod so as to be capable of gripping the drive rod when canted for moving the feed nut, the drive rod, the piston rods, and the pistons conjointly to a forward limiting position of the feed nut when the lever is actuated. A spring biases the feed nut backwardly and permits the feed nut to be canted, to grip the drive rod, and to be moved forwardly and conjointly with the drive rod, the piston rods, and the pistons when the lever is pivoted into an actuated position. A set screw threaded adjustably into a threaded hole in the frame defines a backward limiting position of the feed nut. The screw head engages an outer margin of the threaded hole, in a counterbore, to provide an inner limit to threading of the set screw. A cover mounted over the threaded hole has an access hole sized to permit a screwdriver tip of a smaller size but not the screw head to pass and engages the screw head at an inner margin of the access hole so as to provide an outer limit to unthreading of the set screw.
