es come together and form a stop which prevents the
lid falling backwards and breaking the box. This method of letting-in the
knuckle flush is a useful one for box work because the ordinary stock
brass butt hinge can be used. Attention may, however, be called to the
"stopped butt-hinge," which is specially made to answer the above
purpose; in its action a similar mechanical principle as the one applied
to the box is used.

TYPES OF HINGES.--Fig. 229 is an elongated variety of the butt hinge,
known in the trade as "strap hinge," "desk hinge," or "bagatelle hinge."
As its name indicates, it is used on folding bagatelle tables, small
writing desks, and other types of work that have but a narrow margin on
which to fix the hinges. The long, narrow plates are sunk flush into the
wood, the knuckle or rounded portion projecting.

Fig. 230 is an illustration of the reversible or double-folding screen
hinge. Half the thickness of this hinge is let into each wing of the
draught screen, allowing the screen to be folded either way. The hinge is
costly, but effective in use.

Fig. 231 is a type of pivot hinge which is used to fix at the top and
bottom of a screen.

Fig. 232 is the non-reversible screen hinge and, as its name implies,
will only fold in one direction.

Fig. 233 is a back flap hinge with a specially wide wing, used for the
fall-down leaf of small tables and similar articles.

Fig. 234 is a card table hinge. This is let into the edges of the table,
so that all is flush or level both above and below the surface.

CENTRE OR PIVOT HINGES.--Fig. 235 is a centre or pivot hinge, used on the
top and bottom of wardrobe doors, more particularly the interior door of
a three-winged wardrobe where the method of fixing is confined to the
cornice and plinth. The flange carrying the pins or pivot is let into the
top and bottom of the door, the remaining flange being let into the
cornice and plinth respectively.

RISING BUTT HINGES.--Fig. 236 is the rising butt hinge, used on dining
and drawing-room doors, so that when the d
