  • Patent number: 4741062
    Abstract: A last has an insert shaped to fit within a shoe during its manufacture and a stem fixed on the insert, projecting along an axis from the insert, and formed with radially oppositely projecting front and rear protrusions. A gripper has front and rear jaws formed with respective recesses complementarily engageable with the protrusions so it can accurately hold and position the shoe and last. The protrusions and recesses are formed substantially entirely of planar surfaces, although they can be complementarily rounded, for instance part-spherical. The stem has a radially directed flat provided with indicia and the gripper is provided with a scanner juxtaposable with the flat for reading the indicia. A stationary card on the flat carries the indicia.

  • Patent number: 3961751
    Abstract: A cross-country skiing path has a pair of side-by-side elongated tracks each formed as an upwardly open and longitudinally extending channel in turn each formed of a longitudinal succession of separate track elements that each have a separate web and inside and outside flanges flanking this web. Each inside flange of each element of each row is turned toward an inside flange of a corresponding element of the other row and is provided with an ear extending toward the other row and having a longitudinal length equal to approximately half the overall longitudinal length of the element. Each ear is longitudinally offset from the corresponding ear of the corresponding element of the other row and extends transversely beyond the longitudinal midline of the path. An elongated longitudinally extending connector member, such as a cable, passes through the ears at the midline and interconnects the elements into a chain. Similar connecting members extend through the outside flanges.
