Abstract

194,543. Drummond, C. March 16, 1922. P o r t a b l e turning- apparatus; cutters and cutter b a r s . - Apparatus for trueing valve seats particularly those of internal-combustion motors comprises a cutter 1 having a threaded hole to receive an operating spindle guided at its lower end in the valve guide 6 and at its upper end in a nut 8 screwing into the valve cap opening. A lever 13 may be inserted as shown in Fig. 1 to hold the cutter while the spindle is screwed into position. In operation, the spindle is rotated by a spanner applied to the squared end 5, the nut 8 being rotated as required to maintain pressure on the shoulder 7 and thus on the cutter. For trueing the inclined face of the seating a cutter integral with the operating spindle as shown in Fig. 3 may be employed. In a modification, Figs. 4, 6, and 7, the operating spindle comprises two connected portions between which are located adjustable flat cutters 26, and the guide, nut 8 is assembled in the threaded hole for the sparking plug. In this form the lower end of the spindle is guided by means of a spring-pressed centring member 16.
