The principal objec-tion to this machine was its lack of speed. The same principle,however, had been developed years before in the type revolvingperfecting presses (made by Hoe & Co.) which have two sets oftype forms on separate large cylinders, the sheets being fed in byhand and conveyed from one impression cylinder to the other andagainst the forms by means of fingers or grippers. The sheets werethen delivered on a sheet flier. These presses were especially de-signed for printing books, of which large numbers were required,such as text books and spelling books. The contents of a wholebook could be placed on these cylinders and printed and deliveredat one impression. One of these machines constructed in 1852 66. ooca < hOPi zo u a, 67 ROTARY TYPE-REVOLVING WEB PRESS (fifty years ago) is still in operation at Messrs. D.

In 1881 Hoe & Co. turned their attention to the making ot amachine which should print from one form of type at a greaterspeed than had ever yet been attained. The result was the Ro-tary Type Endless-sheet Perfecting Press. The principle of this
