Detail of Type Case, showing at A how bottom is
fitted to side frame.]

The bottom of the case is fitted into a groove made in the outside
frame, so that it cannot be easily separated. This groove being
slightly higher than the lower face of the side frame, upon which the
case slides back and forth in the rack, keeps the bottom up far enough
to allow it to pass clear of the runs, or of any case or shelf below.
The partitions are made by strips across the full width of each section
of the case from outer frame to outer frame or to crossbar. The strips
are crossed at the corners of the boxes by mortising each piece one half
of its depth at the proper place--one from above and the other from
below--and dovetailing the cross pieces together. (Fig. 4.) The corners
of the boxes are then re-enforced by brass clasps made to fit over the
top of the partitions and held by a long pin driven down through the
dovetailed partitions and clinched at the bottom of the case. (See Fig.
5.).

_Cases for Various Purposes_

While wooden cases are used by printers chiefly for holding type fonts,
they are now also used for a large variety of auxiliary material which
it is necessary to keep more or less carefully classified in convenient
containers. The increasing quantities and varieties of this material now
needed in an average composing-room make convenient receptacles and
orderly, systematic arrangement a necessity if the work is to be carried
on without excessive waste. In no other trade is there a greater
multiplicity of details to be considered in order to obtain a finished
product, and a thoughtless, unnecessary waste of time, effort, or
material in attending to these details adds enormously to the expense of
the product. And so it is becoming the practice of good managers to use
cases more abundantly than formerly and to store them in convenient
racks and cabinets, so that this large mass of material may be kept
classified and may be obtained quickly when needed.

Besides the ordinary pair of upper case and lower case, many styles of
single cases are made to hold a complete font of capitals, lower case,
figures, points, etc., and others are planned to hold small capitals in
addition. Some are made for fonts of capitals, figures, and points only;
some for figures only (especially for time-tables and tabular work), for
fractions, accented le
