...that the inventor of the electric motor was a blacksmith named Thomas Davenport? Described as "a brilliantly unsuccessful inventor", Davenport invented the first rotary electric motor. In 1836 he headed out -- on foot -- from his Vermont home to file a patent application at the Patent Office in Washington, D.C. By the time he got there, he had squandered away his money and couldn't afford the $30 filing fee so he turned around and went home. When he later mailed in his application with money he'd raised, the Patent office was destroyed in a fire. He did finally get credit for his invention on Feb. 5, 1837.

Definition

This class provides for (a) an article comprising an upperbody* and an underbody* for simultaneously receiving indicia on the upperbody and the underbody as a member produces that indicia on the upperbody; and (b) a method of or apparatus for simultaneously producing indicia on the upperbody and underbody of such an article.

(1) Note. An asterisk (*) in these definitions denotes a term defined in the glossary for this class. (2) Note. The term "body" includes a sheet in the form of a strip*, a leaf*, a book* or any other article subject to a process or apparatus of this class. (3) Note. The indicia impressed on the upperbody may be visibly produced on the upperbody, or alternatively the upperbody may remain visibly blank. (4) Note. There may be more than one underbody to which indicia is transferred. (5) Note. Either or both of the bodies may be flexible. (6) Note. The indicia generally comprises a written character. SCOPE OF THE CLASS Included in this class is a manifold, (i.e., an article comprising superposed bodies on which indicia is to be simultaneously produced) which may include (1) a transfer means interposed between the bodies such that a pigmented delineation of an impression* on the upper-body* will be made on a surface of the under-body*, (2) a transfer means comprising a coating on one of the bodies or (3) a component of one of the bodies which causes an image to be visible thereon after being subjected to pressure. Also included in this class is an apparatus particularly adapted to support a manifold as indicia is produced on the upper-body thereof such that a similar indicia is produced on the under-body. The corresponding method of simultaneously producing an image on the upper-body and the under-body of a manifold is also included in the scope of this class. In many instances, claimed subject matter includes manifolding articles in the form of strips*, books* and leaves* as well as such articles combined with apparatus such as feeding members, platens, storage means and holders. A substantial number of subclasses involve collections of such cooperating or "external" apparatus with particular manifolding articles. (1) Note. In this class, a patent is placed in a subclass based on the configuration of the manifold prior to the image producing operation.
