Abstract
A device for use in the manufacture of shoes in which the shoe is mounted on a last while being machined. The last is tiltably supported near the heel end while a longitudinally adjustable tip support member supports the tip end of the last. A guide member near the tip support member guides a tool during the machining of the shoe. Adjustment of the tip support member longitudinally to adapt the machine to different lasts is accompanied by adjustment of the tip support member and the guide member respective amounts in a direction perpendicular to the longitudinal direction of the last.

In a device for use in manufacture of shoes;
- a frame, support element in the frame engageable with the heel end of a last in inserted position of the last, a support member in the frame for engagement with the tip end of the last, a tool in the frame operatively engageable with a shoe on the last, a guide member in the frame adjacent said support member operable for guiding said tool as the tool traverses the shoe in the longitudinal direction, means for adjusting said support element and support member together with said guide member relatively in said frame in the longitudinal direction of the last to adapt the device to lasts of different sizes, and control means responsive to movement of said support element and said support member together with said guide member relatively in the longitudinal direction for adjusting said support element and said support member and said guide member relatively in a direction perpendicular to said longitudinal direction, the adjustment of said guide member relative to said support element by said control means being greater than the adjustment of said support member relative to said support element by said control means.
In a device for use in the manufacture of shoes;
- a frame, support element in the frame engageable with the heel end of a last in inserted position of the last, a support member in the frame for engagement with the tip end of the last, a tool in the frame operatively engageable with a shoe on the last, a guide member in the frame adjacent said support member operable for guiding said tool as the tool traverses the shoe in the longitudinal direction, means for adjusting said support element and support member together with said guide member relatively in said frame in the longitudinal direction of the last to adapt the device to lasts of different sizes, and control means responsive to movement of said support element and said support member together with said guide member relatively in the longitudinal direction for adjusting said support element and said support member and said guide member relatively in a direction perpendicular to said longitudinal direction, said control means comprising a pair of cams having inclined cam surfaces thereon, a follower connected to each of said support member and guide member and engaging a respective cam surface, and means for moving said cams and followers relatively during adjustment of said support element and said support member together with said guide member relatively in the longitudinal direction of the last.
