11.65 HINGES AND BUTTS
A hinge is a device permitting one part to turn on another. In builders’ hardware,
the two parts are metal plates known as leaves. They are joined together by a pin,
which passes through the knuckle joints.
When the leaves are in the form of elongated straps, the device is usually called
a hinge (Fig. 11.70 and 11.71). This type is suitable for mounting on the surface
of a door.
When the device is to be mounted on the edge of a door, the length of the leaves
must be shortened, because they cannot exceed the thickness of the door. The leaves
thus retain only the portion near the pin, or butt end, of the hinge (Figs. 11.72 to
FIGURE 11.70 Heavy strap hinge. FIGURE 11.71 Heavy tee hinge.
