Telegraph ticker patent

In 1846, the first U.S. patent for a telegraph ticker that would print letters of the alphabet was issued to R.E. House of New York City (No. 4,464). It was able to print at the rate of 50 words a minute in Roman letters. It had first been publically exhibited in 1844 at the American Institute Fair in New York City. It was widely used for ten years, until replaced by improved versions.
