Description: |
"My invention relates to trapezoidal cutterheads for woodworking-machines such as shown in the reissued Letters Patent granted to me the 29th day of June, 1897, RE11,616 and RE11,617, in which the sides are alternately arranged and alternately inclined inwardly and outwardly with respect to the axial line of the head. such heads are formed with outwardly-projecting ship-breaks at the front ends of the knife-seats, which are also alternately arranged and alternately inclined with respect to the axial line of the head. In practice such chip-breaks wear away in the course of time and the knives require to be frequently sharpened, so that it is extremely difficult to adjust the knives or cutters so that the cutting edges will be in proper position with respect to the head. The object of the present invention is to provide an improved construction of such cutter-heads whereby a gage may be applied thereto to adjust the cutting edges of the knives." |
