Description: |
| This invention is for bandsaws being used for scroll-work, and addresses the problem of backing the blade out of a cut without damaging the blade or pulling it off the wheels. The innovation is to use a convex piece of glass that is just in front of the blade in normal use. When the operators attempts to back out of a cut, the teeth of the saw strike the glass, preventing any further forward movement of the blade. "The effect of the teeth upon the glass is not perceptible, nor are the teeth dulled in any degree by the glass; in fact, experience has proven that with this attachment the saws do not need sharpening as often as formerly, owing to the chisel-edge which is maintained upon the teeth by the occasional contact with the glass. This is an incidental, but by no means unimportant, item of the invention." |
