Description: |
| My invention relates to certain new. and useful improvements in insertible teeth for saws; band, circular, gang, or crosscut; and it has for its object, among other things, to dispense with the use of additional or separate means to secure or hold the teeth in place in the blade, as, for instance, the primitive rivet, the curved separate shank, and like means; also to economize space in the arrangement of the teeth in the blade; also to increase the cutting capacity of the individual teeth, especially in crosscut-saws, and to obviate the swaging or setting of the teeth. To these ends the invention consists, primarily, in the lateral enlargement or thickening of the shank of the tooth at the base and the enlargement of or forming an aperture at the base or lower end of the tooth-receiving socket or slot in the blade to provide for the reception and interlocking therewith of the metal of the tooth as its enlargement is compressed, so as to project the base of the tooth forward and rearward within said enlargement or aperture of the blade flush with the sides of the blade. |
