Abstract
458,492. Tool-rests. TRESSE, R., 35, Rue de la Liberte, Mauberge, Nord, France. March 13, 1935, No. 7843. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 11, 1936]. [Class 83 (iii)] A tool rest for a lathe or like machine tool has clamping means for a tool holder adapted to hold the latter bv exerting a thrust parallel to the axis of the tool holder. The indexable block 1, which is fastened to the lathe or like slide by a bolt 15 and hollow cap nut 16, provided with a lubricator, has a circular recess 2, Fig. 2, in which is housed a pair of segments 7 and 8, Fig. 3, which are guided for slight circular movement by spring-pressed balls 12 and hinge about the locking-bolt 9 for clamping a tool-holder 6. The latter is provided with circular bosses 5, one of which is engaged by the segment 8 in the position shown, the other boss fitting into a recess in the adjacent corner of the block. A similar recess is provided at 4, Fig. 3, for clamping a toolholder at right angles to the position shown by means of the segment 7. Screws 18 pass through the bosses 18 and bear against the slide to give vertical adjustment to the holder 6 prior to clamping which is effected by a conical wedge 10 adjusted by a screw 11.
