tymp (複数形 tymps)

1. A hollow water-cooled iron casting in the upper part of the archway of a blast furnace in which the dam stands.
   • 1868, Francis Herbert Joynson, The Metals Used in Construction

     About five or six inches beneath the tymp, also a little in advance of it, is placed a stone called the dam-stone, which is in the shape of a prism. It is securely fixed by means of a strong piece of iron of a peculiar shape, covering its outer side, and called the dam-plate.
