CPC B64B1/00: Lighter-than-air aircraft – general category.

For some reason a whole series of 1890s patents focused on eyelets in fabric (and not aircraft) are (mis?)classified under this category. The same patents are usually also classified under IPC B64B1/000 and often that's their only classification in the IPC system according to the metadata from http://patft.uspto.gov.
