Description:
"My invention consists of a dog for holding the log on the head-block, mounted on a vertical screw having a quick pitch, so that it can be partly or wholly forced into the log thereby, and can be kept in so as not to work loose by the jarring and shaking of the mill; and it is specially applicable to the dogging of frozen logs, in which the ordinary dogs will not hold at all."
