"My invention has for its object to so construct a cut-off sawing-machine as that the saw will revolve about the log that is being cut up, whereby I am enabled to cut a log of a given diameter with a saw of half the diameter of a stationary saw, with a corresponding reduction of gage, weight, and power required to drive it. The invention consists, primarily, in the manner of hanging the saw, and in the mechanism for driving it, while it also gives it a planetary motion; and, secondly, in the devices for operating the spiked roller, on which the log lies, to feed it up to the saw."
