Was the first manufactured typewriter in 1870?

The first commercially successful typewriter was developed in 1873 by Christopher Latham Sholes, along with his colleagues Carlos Glidden and William Austin Burt. While there were earlier attempts at creating typing machines, Sholes' design, which eventually led to the QWERTY keyboard layout, became the first widely produced typewriter. The machine was patented in 1868, but it wasn't until 1873 that it was manufactured and sold by E. Remington and Sons.
