Rider, Toronto, granted 8lh Febru- ary, 1897 ; 6 years. Claim.—In a machine for making excelsior packing, in combination a rotating disc secured on an adjustable shaft, sets of scoring knives equidistant and supported in radial guide ways, and means for causing reciprocating movement to knives to cause them to travel in a straight line over the chords of the arcs of a concentric circle, and to simultaneously keep them parallel with the chords of each arc from end to end as they rotate. In combination with a rotating disc, supporting blocks peripherially equi- distant and provided with side grooves, substantially radial recesses with tongues to fit into the grooves, cylindrical discs provided with a plurality of disc-shaped abutting scoring knives, suitably journalled and having cylindrical shanks extending through corresponding holes in supporting blocks, means for reciprocating the blocks, supplemental shanks to the disc and arms secured to the supplemental shanks, with connecting rods, eccentrics, spindles, gear pinions, spur wheel, etc., Wood-Turning Machine. Patentee: Wm. T. Jones, Xew Westminster, B. C, granted 15th February, 1897 ; 6 years. Claim.—A wood-turning machine, comprising a series of fixed cutters, a rotary block, means for rotating the blocks relatively to the carrier, saw for severing the block from the strip, and reciprocating frame for holding and operating a boring tool. The combination with a saw, a boring device, and a block carrier, of a block shifter com- prising a reciprocating carriage, afulcrumed lever hav ing a link connection with said carriage, an eccentric shaft, a finger extended radially from said eccentric shaft, and pins arranged at opposite sides of a slot opening in said lever and adapted to be engaged successively by the finger on th
