material, formed with a head and inserted into 
a hole at the junction of two or more pieces of 
metal, the point after insertion 
being hammered broad so as to 
keep the pieces closely bound to- 
gether. Large rivets are usually ham- 
mered or closed up (riveted) when they 
are in a heated state, so as to draw the 
pieces more firmly together by the con- 
traction of the rivet when cool. It is 
in this manner that boilers, tanks, etc., 
are made. Small rivets are frequently 
riveted cold. Instead of being closed by 
hammering, rivets are now often riveted 
by means of powerful machinery, which 
makes better joints than can be made by 
hand, and executes the work far more 
quickly. In some kinds of metal-work, 
as armor, the metal pin is movable in a 
slot, allowing one of the plates of metal to 
slide over the other for a certain distance. 
Compare Almain-rivet. 
The armourers, accomplishing the knights, 
With busy hammers closing rivets up,
