 +====== Hard Pull ======
 +
 +In justifying the head of a press for a short pull, which is done by putting solid blocks of wood into the mortises of the [[c:​cheeks|cheeks]],​ it is called an //Hard Pull//. — //M//.\\
 +This relates to wooden presses; but, instead of the blocks of wood, scaleboard is now used, additional pieces of which are put into the mortises, by lowering the head, which is again tightly screwed up: in the Stanhope Press, and in [[c:​clymers-press|Clymer'​s]],​ it is accomplished by shortening the coupling bar, by means of a screw; in Cogger'​s press, by a screw through the head; and in [[c:​copes-press|Cope'​s press]], by putting pieces of plate iron upon the crown of the platen. In Sherwin and Cope's Imperial press, by turning a screw attached to a wedge placed in the front, above the spindle; Mr. Hopkinson has adopted the same method in Cope's press, placed on the near side.
