Abstract

745,300. Grinding valve seats. SOULET, A. P. April 17, 1953 [May 14, 1952], No. 10619/53. Class 60 Apparatus for trueing valve seats comprises a grinding wheel 11 carried by a sleeve 10 which has a stud 12 engaging a longitudinal groove 9 in a sleeve 6; the sleeve 6 is rotatablv mounted by ball bearings 7, 8 on a sleeve 4. The sleeve 4 fits on a guide rod 2 located in the valve stem guide 3, the upper end 5 of the sleeve being frusto-conical and wedged over the end of the guide rod. The sleeve 10 is closed at its upper end by a plug. 13 having a socket to receive a driving member, and a spring 14 located between the plug 13 and the upper end of the sleeve 6 normally holds the grinding wheel 11 raised out of contact with the valve seat 1- When the grinding wheel has reached its operating speed it is urged down into contact with the valve seat.
