This information came in a later letter. Meredith had been hunting the history on the vibrator type thresher and this all turned up after he had mailed the previous material. Like Meredith says, 'That's the way it goes, you can hunt and hunt for material, then Bang! all at once it turns up.' So it is here, though a bit delayed.

Thanks for all your efforts, Meredith Anna Mae.

The Aultman & Taylor Co. was founded in 1867 to build the then new type vibrating thresher. The vibrator principle being a straw rack hanging on rods from frame of thresher behind the cylinder, being given a back and forth motion by pitmans and cranks. Then as the threshers were improved, the grain pan was fixed likewise only it was timed to move in opposite direction of straw rack; this tended to counter balance machine and make a much smoother operating machine.

In the early 1830's the Pitts were experimenting with a perforated board shaken longitudinally with the 'ground hog' thresher, this being before the adoption of the endless apron thresher. The first patent granted on the vibrating principle of separation was granted to a W. Pierpont of Salem N. J. on May 7, 1850. Cyrus Roberts of Belleville, Illinois was the first to invent and carry forward to successful completion devices necessary to the development of the modern vibrating type of thresher.
