Abstract

594,771. Tools and tool-holders. WEDDELL, R. R. April 28, 1944, No. 8023. Convention date, May 10, 1943. [Class 83 (iii)] Boring-bars milling-cutters.-Inserted blade milling cutters, lathe tools, boring-bars &c., have a body 10 with open-ended recesses 11 for the blades 12, each of which is provided with a number of surfaces 17, 28 forming obtuse angles with a side face 20, to coact successively after repeated regrindings with an adjusting grub-screw 21 in a tapped hole 22 intersecting the recess ,11 at an acute angle. One of the adjusting surfaces is formed by the end of the blade remote from the cutting edge. Each recess 11 and blade is of triangular section and a grub-screw 17 perpendicular to a flat face of the blade locks it in the recess after adjustment. The screws 17, 21 are offset from the axis of the blade as shown in Fig. 4 to avoid mutual interference, and when the screw 21 has reached the limit of its adjustment with the surface 28 it is retracted in the hole 22 to engage the next surface 27. One or more of these surfaces may be formed at the end of an inclined groove 30 in the face 20 of the blade, and in a modification, shown in Fig. 7 as applied to a fly-cutter, two opposed grooves 30, 32 are provided in the blade for co-action with two inclined screws 17, 21 which adjust and lock the blade in the recess. The blades may be formed by machining, forging or casting and the recesses 11 by broaching &c.
