Scientific American Reports To 19th Century Inventor Ayars On Invention

INVENTIONS in the 19^th Century Victorian period began to change the way the world operated. Dishwashers, electric light bulbs, gramophones, picture cameras, radios, typewriters all date back to the 19^th century.

SCIENTIFIC AMERICAN was founded by inventor and publisher Rufus M Porter in 1845 as a weekly that focused on what was going on at the U.S. Patent Office, reporting on a broad range of inventions. Porter sold the publication to Alfred Ely Beach and Orson Desaix Munn ten months after founding it.  The magazine aided inventors in sending their applications to the Patent Office.

Offering four ALS by Munn & Co. to inventor Benjamin Ayars, dates ranging from 1869 to 1870, 6 x 9 ½ on Office of the Scientific American, Patent Office Department, 37 Park Row, New York.  A fifth letter is an explanation of the fees and services offered.

BENJAMIN AYARS was one of many inventors. He created a wheat threshing machine and a mail bag delivering apparatus, among other products.

The highlight of the grouping is a letter regarding Ayars application for a patent for improvements to threshing machines.  “…We have to communicate that the office will not allow a patent on the claim for attaching the fan wings to flangers in the shaft asserting it possesses no advantage over the ordinary method. This claim is not apparently of great importance to you compared with others, but we desire to obtain it if possible…”  The letter contains a response, not signed by apparently from Ayars. “…The advantages of the flangers is giving strength to the shaft, it being cut to the center to let the arms of wings…made strong enough…”
