 +====== Ruthven'​s Press ======
 +
 +Ruthven'​s patent press differs materially from all others. Instead of the [[f:​form|form]] of types being rolled under the platen, and back again when the impression has been made, the type form remains stationary upon the iron table, the platen is drawn over it, and the impression is obtained by means of a lever working vertically like the handle of a pump, and acting by connecting levers upon both sides of the [[p:​platen|platen]],​ so as to draw it down with ease and effect. It is a good and powerful press, but the [[h:​head|head]] and platen are heavy and require exertion to push them back off the form, and more particularly as the [[r:​ribs|ribs]],​ if the grooves in which the wheels attached to the head and platen travel may be so called, form an inclined plane, which causes the platen to come forward over the form with but little exertion. ​
