The Gem apple parer made by Reading Hardware Company was based upon a design patented by Adolph Rippien (1827-1897) of Reading, Pennsylavia. Rippien was granted letters patent for his apple parer on October 5, 1880 and stated that one of his goals was to make the parer as compact and small as possible to, "facilitate transportion and storage."
Rippien's design is truly unique in that he used a knife arm sandwhiched between two turntables to engineer a slow return parer. One of his inventive claims was for two turntables rotating in opposite directions, one to carry the knife arm as it pares the apple and the other to carry the knife arm back to starting position.
The second patent embossed on the Gem was granted to Levi D. Farwell and Artemus W. Goddard on May 5, 1868 for the push-off mechanism. The push-off on our example is broken as are many for this model.
Rippien was granted five patents related to apple parers, all of which were assigned to William M. Griscom, Matthan Harbster, and William Harbster, partners in the Reading Hardware Company. William Morris Griscom (1823-1919) was married to Ellen Harbster (1828-1864), sister to William Harmen Harbster (1823-1885) and Matthan Harbster (1831-1912).
