oor is opened the door rises
sufficiently to clear the thickness of the carpet. This hinge has also an
advantage over the ordinary butt hinge in that it is self-closing,
_i.e._, the weight of the door _plus_ the bevel on the hinge joint causes
the door to close. Band and hook hinges and other ordinary varieties are
too well known to require illustrating.

ACUTE ANGLE HINGEING.--Fig. 237 is a sectional plan of a corner cupboard
showing a good method of hingeing the door. The inset _a_ shows an
enlarged view of the corner carrying the hinge, also the adaptor piece
_c_, which is fitted to the inside edge of the cupboard so that the
hinged edges are at 90 degrees to the face. This is a far better and
stronger method than that shown at _b_, which is often attempted with
disastrous results. The incorrect method _b_ allows insufficient wood for
fixing purposes, and in nearly all cases the thin edge of the door breaks
away during the making and fitting, or soon after completion. The adaptor
piece may have a face mould worked upon it to give a pilaster-like
appearance if fancy so dictates.

INSIDE HINGEING.--When a door is being hung _inside_ the carcase (that
is, not hinged _over_ the ends) it is permissible, in the case of light
work, to let the whole thickness of the hinge into the door; and when
screwing the door to the carcase it is usual to fix the knuckle of the
hinge flush with the face of the carcase, thus allowing the door frame to
stand back, making a break of about 1/8 in. with the face. The marking
gauge should be set to the full width of the hinge; the mark, gauged on
the inside of the carcase end, thus forms a line to guide the worker
whilst fixing the door. To successfully fix a door it generally requires
two persons, one to hold the door in position, whilst the other bores the
holes and fixes the screws.

Fig. 238 shows the correct method of fitting butt hinges on high-class
work. One wing of the hinge is let into the door, and the other wing is
let into the carcase or door jamb, thus distributing a proportion of the
weight to the carcase end instead of allowing the
