or the guide in contact with the pattern, to follow the pattern we have movably mounted the knife upon the carrier, and have provided means for holding it or its guide against the pattern. As we have stated, our invention is preferably embodied in a sole-rounding machine in which the pattern is stationary and the support upon which the carrier is pivotally mounted is rotated to move the rounding-knife about the pattern, as such a machine can be of simple and compact construction, and can be used to cut soles from strips of material as well as from pieces of material containing only enough stock for a single sole. When the mechanism above referred to is embodied in such a machine the force exerted upon the knife to cause it to travel around the pattern always acts in a direction substantially tangential to the curve of the pattern, so that the knife, or its guide in contact with the pattern, is not forced against the pattern in passing around the heel and toe so as to produce wear of the contacting parts or offer a resistance to the operation of the machine. Also, the force exerted upon the knife does not tend to pull the knife away from the pattern at any point in the rounding operation; and, moreover, the oscillating movement of the carrier retards the movement of the knife when passing around the heel and toe of the pattern and into the curves of the shank, and thereby still further decreases the liability of the knife leaving the pattern. To adapt the machine for operation with patterns of different sizes it is provided with mechanism for moving the cam, which imparts inward and outward movements to the carrier during the operation of the machine, and such mechanism has means of adjustment whereby the extent of movement imparted to the cam may be varied to suit the size of the pattern used in the machine. The extent of movement imparted to the cam may be varied considerably without interfering with the ease of operation of the machine, as the cam in combination with the mechanism for oscillating the carrier will actuate the carrier to cause the rounding-knife to travel in a path corresponding approximately in shape to that of the pattern. To increase the range of adjustment, however, we preferably provide the mechanism for oscillating the carrier with means of adjustment whereby the extent of the oscillations imparted to the carrier may be varied. The stop mechanism which we have provided is constructed and arranged to allow a relative movement of the pattern and rounding-knife due to the momentum of the various operating parts of the machine after the driving-shaft has been disconnected from the source of power, and to thereafter return the pattern or knife to normal position. The novel features of this mechanism consist in the improved mechanism for disconnecting the driving-shaft from the source of power and stopping the rotation of the shaft, in the construction and arrangement of the spring connection which allows the relative movement of the pattern and knife after the shaft is disconnected from its source of power, and in certain details of construction specifically described.
