Abstract

221,030. Badcock, F., and K. B. Patents, Ltd. June 20, 1923. Portable turning-apparatus; drills and cutters. -A tool for trueing valve seatings comprises a body 10 slotted to receive a number of cutters 15 which are clamped by screws 17 acting through plungers 18 bevelled to conform with the upper surfaces of the cutters. The bottoms of the slots 14 may be inclined at 45‹ to the tool axis and the cutters have cutting edges at right-angles to their length. In order to assist in imparting a smooth finish to the seating the cutting edges of alternate cutters may be set back as shown at 21 or some of the slots may be displaced from a truly radial position. The body is provided with a recess 22 and the operating spindle 24 rotated by a spanner applied to the portion 27 is fitted with a ball 25 which enters the recess 22 and carries a pin engaging one of the slots 23, pressure being applied by means of the handle, 28. The tool is located by means of a spindle 29 engaging the valve guide, a series of such spindles being provided for guides of different sizes. The cutter may be set by means of a gauge, Fig. 4, having a graduated conical surface 30 and a tubular portion 31 to receive the locating spindle- 29.
