Ford Typewriter Ford Typewriter The Ford typewriter was an early prototype typewriter introduced in 1895 by Eugene A. Ford, who later became chief development engineer at IBM (no relation to Henry Ford who founded the Ford Motor Company). It was a commercial failure and only a few were manufactured. Unlike many competing typewriters of this time, it was a forward-striking machine, meaning the hammer struck forward against the paper which was held against the platen roller, instead of up from underneath. This allowed the typist to see the text as it was typed, which was not possible in most other typewriters of
Needle roller bearing Needle roller bearing A needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Ordinary roller bearings' rollers are only slightly longer than their diameter, but needle bearings typically have rollers that are at least four times longer than their diameter. Like all bearings, they are used to reduce the friction of a rotating surface. Compared to ball bearings and ordinary roller bearings, needle bearings have a greater surface area in contact with the races, so they can support a greater load. They are also thinner, so they require less clearance between
