Abstract
9871. Dymond, G. C., [Hoffman, M. J., and Harbaugh, C. B.]. May 6. Milling; end facing.-The spindle 13, Fig. 1, of a cutter 5 for surfacing the seating 2 of a valve is supported by a conical piece 4, which is provided with a conical internal recess 4<a> and with screwthreads on its exterior and interior faces, so that it can be attached to valve casings having either external or internal screw-threads on the cap of the casing, as shown in Figs. 1 and 3 respectively. The cutter 5, Fig. 6, is conical in shape having flat edges 5<a>, and has a set of cutting-edges 11 at each end on the conical surfaces and a set 11<a> on its larger flat face, so that it can operate upon conical or flat valve seatings, as shown. The cutter spindle 13 can be fed forward by a screw 8 operated by a hand-wheel 14. The spindle 13 is rotated by a crank-handle 14<a>.
