Abstract

137,957. Mayne, J. S. March 22, 1919. Portable turning-apparatus.-Apparatus for re-seating valves, cocks, &c. comprises a cutter 5 screwed to a spindle 11 having a handle at its outer end and carrying a slidable conical sleeve 10 adapted to seat in the mouth of the valve to guide the spindle, and between which and the handle is situated a spring 13 which serves to hold the sleeve in position. The projecting end 14 of the spindle may also serve as an additional guide, or it may be fitted with a pilot cutter 15, having at its lower end cutting-edges, which clears away inequalities from the socket of the valve-seating and makes a fitting guide for the upper, and plain, part of the cutter 15. Detachable rings of different thickness may be fitted to the sleeve 10. According to the Provisional Specification, caps or rings may be used in conjunction with the projecting end of the spindle to adapt the apparatus for different valve sockets.
