Mr. Smythe had been giving his second-grade students a short lesson on science. He had explained about magnets and showed them how they would pick up nails and other bits of iron. And now it was question time....

Edison patentIn 1924, Thomas A. Edison was issued a U.S. design patent for a "Design for a Phonograph Cabinet." (Design patent No. 69068). In addition to a front and side elevation, the patent showed an enlarged portion of the front elevation showing more clearly the details of one of the panels or grilles. The design patent covers the ornamental design for a phonograph cabinet as shown for a term of 14 years. A design patent protects only the appearance of the article and not structural or utilitarian features. |
