INVENTIONSin the 19th Century Victorian period began to change the way theworld operated. Dishwashers, electric light bulbs, gramophones, picturecameras, radios, typewriters all date back to the 19th century.

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

Offering fourALS by Munn & Co. to inventor Benjamin Ayars, dates ranging from 1869 to1870, 6 x 9 ½ on Office of the Scientific American, Patent Office Department,37 Park Row, New York. A fifth letter isan explanation of the fees and services offered.

BENJAMINAYARS was one of many inventors. He created a wheat threshing machine and a mailbag delivering apparatus, among other products.

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