<P> This candid fault - finding is just what we need . We had better have it now than after we begin manufacturing . Where Clephane points out a weak lever or rod let us make it strong . Where a spacer or an inker works stiffly, let us make it work smoothly . Then, depend upon Clephane for all the praise we deserve . </P> <P> Sholes took this advice and set to improve the machine at every iteration, until they were satisfied that Clephane had taught them everything he could . By this time, they had manufactured 50 machines or so, at an average cost of $250 . They decided to have the machine examined by an expert mechanic, who directed them to E. Remington and Sons (which later became the Remington Arms Company), manufacturers of firearms, sewing machines, and farm tools . In early 1873 they approached Remington, who decided to buy the patent from them . Sholes sold his half for $12,000, while Densmore, still a stronger believer in the machine, insisted on a royalty, which would eventually fetch him $1.5 million . </P> <P> Sholes returned to Milwaukee and continued to work on new improvements for the typewriter throughout the 1870s, which included the QWERTY keyboard (1873). James Densmore had suggested splitting up commonly used letter combinations in order to solve a jamming problem caused by the slow method of recovering from a keystroke: weights, not springs, returned all parts to the "rest" position . This concept was later refined by Sholes and the resulting QWERTY layout is still used today on both typewriters and English language computer keyboards, although the jamming problem no longer exists . </P> <P> Sholes died on February 17, 1890 after battling tuberculosis for nine years, and is buried at Forest Home Cemetery in Milwaukee . </P>
