Hi Paul. The interesting piece you produced of William Frank Howard is a
provisional specification.
This is - in the words of the Patent Office -
Quote:

A provisional specification is usually filed to establish priority of the invention in case the disclosed invention is only at a conceptual stage and a delay is expected in submitting full and specific description of the invention. Although, a patent application accompanied with provisional specification does not confer any legal patent rights to the applicants, it is, however, a very important document to establish the earliest ownership of an invention. The provisional specification is a permanent and independent scientific cum legal document and no amendment is allowed in this. No patent is granted on the basis of a provisional specification. It has to be a followed by a complete specification for obtaining a patent for the said invention. Complete specification must be submitted within 12 months of filing the provisional specification. This period can be extended by 3 months. It is not necessary to file an application with provisional specification before the complete specification. An application with complete specification can be filed right at the first instance.

They can describe these legal matters far better than me, but the essence is that this is not a patent, but a sort of priority to establish the first rights. Sure the invention of Howard was never followed up with the request for a patent.
