Abstract

1,151,382. Sawing. J. C. LEE. 1 March, 1968 [22 March, 1967], No. 13521/67. Heading B5L. A saw blade comprises a succession of groups of teeth, each group comprising a raker tooth 10 having a cutting edge of chisel edge form followed by at least two finishing teeth 11, 12, each of which has side cutting edges 11b, 12b which project beyond the raker tooth at opposite sides of the saw blade respectively and end cutting edges 11a, 12a which comprise cutting points which project beyond the cutting edge of the raker tooth at said opposite sides respectively and are bevelled to lie below the cutting edge of the raker tooth at the opposite sides to said opposite sides. The saw blade may be of the straight reciprocatory type or, as described, of the circular type, and each group consists of a raker tooth followed by two pairs of finishing teeth 11, 12, the groups being separated by gullets 14. The raker teeth are without axial rake and have a radial rake of 20 to 30 degrees. The finishing teeth have side cutting edges 11b, 12b projecting on opposite sides of the raker teeth, respectively, and the edges at the other side of the blade are in the same planes as the edges of the raker teeth. The outer ends of the finishing teeth are bevelled so that in the central region of the blade, the raker teeth project beyond the edges of the finishing teeth. The finishing teeth have an axial rake of 20 to 30 degrees and a negative radial rake of 20 to 30 degrees.
