The Niagara Machine & Tool Works, Buffalo, N. Y., recently obtained a patent on a slitting gage that is being applied to rotary sheet metal shears. The accompanying illustration shows a hand slitter equipped with the gage. The gage consists essentially of a bar extending transversely through the gap of the machine and against which one edge of a sheet bears so that it is cut to the required width. The bottom of the transverse bar rests upon the frame of the machine and is connected at the ends to sliding blocks. These blocks may be clamped in any predetermined longitudinal position along the machine so that the distance from the rotary knives to the gaging bar may be altered to suit a job. They are clamped on machined surfaces of the frame by means of T-bolts. The only member of the gage subject to wear is the transverse bar, and this can be readily re placed, as it is located on the sliding blocks by means of dowels and attached by bolts. The gage can be removed from the shear when it interferes with such operations as circle or ring cutting. |
