- The cylinder stops, and current operates the sluggish press-magnet, causing its armature to be attracted, thus lifting the platen and its projecting arm. Frank Lewis Dyer. Edison, His Life and Inventions.
- The screw was turned down, the platen was pressed against the sheet of paper, and the printing was done. Rupert S. Holland. Historic Inventions.
- It has ball-bearing type bar joints, giving accurate alignment and light key action, the platen rolls to show the work, and the carriage locks at the end of the line, protecting the writing. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
- I was experimenting, he says, on an automatic method of recording telegraph messages on a disk of paper laid on a revolving platen, exactly the same as the disk talking-machine of to-day. Frank Lewis Dyer. Edison, His Life and Inventions.
- From the diagram it will be seen that the armature of the latter has a long, pivoted extension arm, or platen, trough-like in shape, in which the paper tape runs. Frank Lewis Dyer. Edison, His Life and Inventions.

- Then the screw was raised by the handle, the platen was lifted with it, and the printed paper was ready to be taken out. Rupert S. Holland. Historic Inventions.
- In this press (see Fig. 123) the platen is forced downwardly by a compound lever applied to a toggle joint and is raised by springs on each side. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
- The idea of replacing the platen by a cylinder was not a new one. Various. The Wonder Book of Knowledge.
- He watched the master dab the type with ink, slide them under the platen, and having pressed it down, take out the printed page. Rupert S. Holland. Historic Inventions.
- The platen had a spiral groove on its surface, like the disk. Frank Lewis Dyer. Edison, His Life and Inventions.
- The flat bed on which the types rested was held up by other cross timbers, while through another passed a wooden screw, by the aid of which the wooden platen was forced down upon the types. Various. The Wonder Book of Knowledge.
