Abstract

597,438. Milling-cutters. WHITICKER, E., CHAPMAN, P. E., and RUSTON & HORNSBY, Ltd. Aug. 18, 1945, No. 21113. [Class 83 (iii)] In an inserted blade milling-cutter, the blades 9 are secured in wedge-shaped slots 8 by transverse cotters 7, the axes of the cotter holes 5 and of the slots 8 being at a small angle to each other to provide the wedging action. The axis of each cotter hole is parallel to the axis of rotation and each slot is inclined at an angle a, which may provide all or part of the negative rake angle e. The wedge formation of each slot may be provided by both walls of the slot or the wall adjacent the cotter hole may be radial ; the bottom 10 of the slot is parallel to the axis of rotation. The cotters 7 have a flat tapering face inclined at the same angle a as the slots. The body has recesses 16 adjacent to each blade to permit the escape of chips and is slotted at 2 and 3 for securing to the driving-spindle by bolts passed through holes 4.
