They Invented What? (No. 183)

Posted in They Invented What? by Jake Ward on September 22, 2010

U.S. Pat. No. 3,402,485:  Animal track footwear soles.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A molded footwear sole for laying of simulated tracks of an animal,said sole comprising
          a forepart portion having a normal tread surface,
          a heel portion having a normal tread surface,
          projecting sole portions integral with the forepart portion and extending beyond the normal tread surface of the forepart portion, said projecting forepart portions being of a configuration and arrangement simulating the configuration and arrangement of bottom portions of a selected side first foot of a selected animal, and
          projecting sole portions integral with the heel portions and extending beyond the normal tread surface of the heel portion, said last named projecting sole portions being of a configuration and arrangement simulating the configuration and arrangement of bottom portions of a second foot of the same selected side of said selected animal,
          said projecting sole portions comprising a tread surface which, when said sole is resting on a plane, separates the entire normal tread surface of the sole from the plane, whereby upon pressing said sole into soil, as by walking, said sole imparts an imprint simulating that made by said animal.
