916,112. Tool-holders. DE VLIEG MACHINE CO. July 14, 1961 [July 26, 1960], No. 25558/61. Class 83 (3). A tool-holder, such as a boring head, comprises a body 84 into which a tool-supporting member 86 with keys 84 is slidably fitted. The member 86 is provided with external threads on which a graduated dial member 92 is adjusted to give the required depth of cut. The dial member has a conical surface 102 adapted to seat against a similar surface 102 on the body. The member 86 is also provided with an internal screwed bore 104 for a draw-screw 106 which bears against a shoulder 110 of the body. A bevel gear 108 is provided on the end of the draw screw which engages a second bevel gear 120 rotatable, on an axis at right angles to the first gear, in the body. A socket 124 in the sleeve 122 of the second bevel gear is engaged by a wrench 134 to clamp the member 86 in the body. A similar arrangement for clamping a tool-socket or adaptor in a chuck-like holder is described.
