The Imposing-stone—a piece of marble or other flat stone set upon the work table. After properly leading the type,
The Chase—an iron frame cast to hold the type for printing—should be placed over it. The space between the type and chase should then be filled out with
Fig. 155.—Locking-up a Form.
Furniture.—Metal furniture consists of hollow metal blocks of various sizes, while wooden furniture comes in strips of different widths, which may be cut up into the lengths required. Use a mitre-box similar to the one described in Chapter I in cutting the wooden furniture.
Locking-up a Form.—The type is locked-up by means of iron wedges known as "quoins." There are two forms of these, those driven together by means of a "shooting-stick" and mallet, as shown in [Fig. 155], and those locked by means of an iron key, such as is shown in [Fig. 156]. The latter kind is probably the most commonly used to-day. Before locking the form, the type should be levelled with a planer, which is nothing more than a block of hardwood with a smooth, even surface. The planer should be set upon the type and given a few light raps on the top with the hammer, until the face of the type is even. Then lock the form securely, being careful to have as equal pressure as possible on all sides, to prevent the type from springing. The form is then ready for the press.
