Abstract
August 3, 1822.—Machine saws for felling trees have not found great favour, but many have been invented. An early example was the subject of Mouret's patent granted for five years in France on Aug. 3, 1822. The saw is mounted on rollers and is moved to and fro by manually operated gear, being guided in a frame so as to have a slightly circular motion. The frame itself is also on rollers, and is caused to advance slowly towards the tree with each cut of the saw by means of weights and rope gearing.
