Bevel scroll-saw.
A machine for sawing shiptimber to the proper curve and bevel. The saw is mounted on a circular frame a, and reciprocated by means of a rod b and eccentric c. By inclining the saw in its frame any required level may be cut, the curve being given by moving the carriage d d on its circular track a, so as to vary the presentation of the timber. The timbers rest on the rollers f f of the table; but if long, are likewise supported by the rollers k k of the carriages e e, which run towards and from the saw on tracks i i. To change the presentation for oblique or circular cut, the carriages i i move in concert —if the timber be long enough to bring them both into action — around the track g, against whose flange the guide-rollers h h bear. |
