Description: |
| The inventor's analysis of the failings of existing band mills was similar to that of Charles Esplin (patent 341,376), but where Esplin's designs failed to improve the state of the art, Prescott's succeeded. "My invention relates to that class of sawmills called 'band-mills,' and may be said to be an improvement upon the mill shown and described in my prior application, Serial No. 207,142, filed July 3, 1886. The object of the present invention is to provide for adjusting the upper band-wheel and to make the adjusting device exceedingly sensitive, so that the slightest change in strain will effect a movement of the said wheel, thereby taking up even slight slack almost instantly and keeping the saw always under proper strain." The inventor's 1910 monograph, "The Evolution of Modern Band Saw Mills for Sawing Logs", notes that of this sawmill design, "over 150 built and most of them are in service at the present time, 1910". |
