Abstract

196,868. Jones, A. A. Oct. 18, 1922. Portable turning-apparatus; drills and cutters, -A hand tool for repairing valves and valve-seats of internal-combustion engines comprises a double or combination cutter with teeth 5 at one end to face seats and teeth 19 at the other end to face valves. Removable bushes 7 receive a pilot bar 2 that is clamped in a handle 3 by a screw 9. The handle is bored for a tommy bar 4 that serves also as a key for the screw 9. Projecting screws 14 engage recesses in the cutter to impart drive when operating on seats, the pilot engaging the valve guide. When facing valves the cutter bush engages the stem 18 which is clamped in the handle 3. The cutter is held either by its knurled surface or by means of flats 21 in a vice &c. Sets of cutters, bushes, and pilots may be provided.
