(under subclass 85) Machines which operate on that portion only of a sole which lies between the breast line and the ball line of a shoe to (1) bevel the side edges of the sole, or (2) remove excess marginal material from the sole so that the contour of the sole forms a continuation of the contour of an attached heel, which operation is termed joining.
(1) Note. The beveling may be for the purpose of (1) forming a space for receiving upper materials or (2) making the sole appear thinner at the shank by beveling the lower corners to produce a shank shape known as a cottage shank.
