The object of this invention is to allow the wheels to be spaced more closely together than usual, enabling the use of shorter sawblades. "In band-saw mills of ordinary construction the rocking shaft or the balancing-levers that are employed to connect and support the columns and to maintain tension upon the saw are arranged between the two band-wheels, necessitating a considerable space between said wheels and also requiring the employment of long band-saws." |
