Mr. George Clymer, of Philadelphia, first began to turn his attention to the improvement of the printing press in the year 1797. Having completed his object, he came to England in 1817, and introduced his improved press under the name of the Columbian Press: he established a manufactory in London, and the first press he constructed here was completed in 1818, and I believe went to Russia.
It is an iron press; there is no screw; the head is a large and powerful lever, which is acted on by other levers to which the bar is attached, and produces the pressure; the platen is attached to the head by a square bar of iron, and the descent is preserved steadily and regularly by two projecting guides, one from each cheek; the platen is raised from the form by a lever with a weight at one end, attached to and above the head, which acts when the pull is eased and the bar flies back.
The power of this press is very great, and I have not heard of any failing or breaking, which is an important fact in its favour. It ranks in the opinion of practical men, generally, as the next in estimation to the Stanhope press. The only objection I have heard to this press, was the length that the pressmen had to reach, and the disadvantage in the pull, by the bar being attached to the off cheek; but Mr. Clymer remedied this by attaching it to the near cheek, which not only facilitates the pull, but also enables the pressman to exert his strength more advantageously and with more ease.
Mr. Clymer died in 1834, but the manufactory is still continued in Finsbury Street under the firm of Clymer and Dixon. I believe the representative of Mr. Clymer is Mr, A. R. Shaw, who married one of his daughters.
