Automatic Saw sharpening. — The most evident advantages of the modern automatic saw sharpening machine over the old practice of hand filing are that the sawyer can always have a number of well-sharpened saws ready for use, so that he need never leave his saw frame idle while he is sharpening his saw; the wear of the emery wheels is much less costly than that of files; and the teeth are always uniform in pitch and shape. The result is that for the same amount of power and of time much more work is produced, less timber is wasted, and the saws last longer. The saving thus effected in a large concern covers the cost of the saw sharpening machinery in a very short time.
The Schmaltz Patent Automatic Saw Sharpening Machines (figs. 129 to 134) have all these advantages, and can be readily worked by any intelligent workman after a little training. All the adjustments can be made whilst the saw is being sharpened.
Special provision has been made against the wearing out of the working parts by the emery dust, the motion being transmitted by hardened steel eccentrics working automatically in contact with steel rollers, while the dust is at once got rid of by a dust guard and an exhaust fan with air pipes.
Fig. 133 the machine for sharpening those in a small fine pitch circular saw similar to what would be used for cutting ivory, horn, or cold metals. |
