Abstract

901,370. Turning valve seats. HUNGER, L. Oct. 8, 1958, No. 32040/58. Class 83 (3). Portable apparatus for turning frusto-conical surfaces such as valve seats, comprises a toolsupporting element connected to a non-rotatable part of the apparatus such that, when the former is rotated about the axis of the surface to be cut, it is continuously traversed in a direction oblique to the axis to generate a frusto-conical surface. The central support stem 13 for the tool is anchored in the valve guide (not shown) and lateral support for the upper part of the tool is provided by a sleeve 31 secured to a bracket supported by the engine block &c. The tool-head 10 is rotated about the stem 13 by a handle 14 secured by a set-screw 19 to an extension 17 of the head. A rod 21 and sleeve 20 provide for depth-adjustment of the tool 16 secured to a slide 43 of the tool-head. The tool is adapted to be traversed across the surface of the seat, at the angle of the slide, by a pinion 41 engaging rack teeth 42 on the slide. To effect a feed movement the sleeve 32 is held against rotation while the tool is rotated by its handle. A threaded lower portion 33 of the sleeve engages a pinion on a cross-shaft in the toolhead, the other end of which carries a worm engaging a worm sleeve 36 rotatable about the end 37 of the pinion 41. The nuts 40 are previously tightened to secure the worm sleeve to the member 37 when feed movement is desired. Specification 901,371 is referred to.
