History of the Typewriter

— 24 — through which work the seventy-eight type-bars, the pressure being given to the types downward by the plunger, C, working through the standard, S, which is bolted to the frame. The upper part of the standard is an oblong rect- angular frame so constructed as to support the horizontal shaft, U, and having across the top of it the projecting arm, R, which sustains the standards, 0' 0", which are the boxes of the shaft, H, which shaft is the fulcrum of the lever, G, the long end of which is connected with the plunger C, by the connecting rod, I, and the short end of which lever, G, is connected with the lifting rod by the connecting Fig. ii rod, F. The paper table is the platform, (), a plate of iron covered with cloth and supported on four feet, one of which is seen at q, grooved to allow them to slide on the guide- bars, T T, which in their turn slide on the guide-bars, I I, the platform being thus made susceptible of both lateral and longitudinal motion. To move the paper in the direction of the lines of printing, a rack is fastened to the under side, the end of which is represented at g' and which is worked by the pinion, U. It will be seen that in the Eddy invention the types remained stationary (excepting as each type descended to give a blow), the paper-sheet moving as each type was struck, to present a fresh place for the next one ; when the end of a line was reached, a tiny bell gave warning of the fact, and the paper-carriage
