Trellis or Trellice. Open grating or lattice-work, either of metal 

 or wood ; the name is usually confined to such as are formed 

 of straight bars crossing each other. In architecture its use 

 is mainly for screens, doors and windows. The usual term 

 is " Trellis- work." 



Trench. In carpentry, a cut or channel wrought for use or orna- 

 ment ; a term largely applied to " wall " or " string-boards " 

 in staircase- work or building, where they are "trenched" to 

 receive the step-ends, i.e., the "treads," "risers" and 

 " nosings." In other instances trenching is resorted to in 

 producing circular work, door- and window-casings, the 

 thickness being reduced in parts to admit of bending on the 

 centring. 



Trencher or Platter. A "trencher plate" or "platter-board," 

 usually a turned piece of maple or sycamore, which served 

 until recent times the purpose of the earthenware plate, 

 pewter and silver or even gold plates serving at higher tables. 



Trenching Plane. One of a set of carpenter's hand-tools, retaining 

 a place in that number diminished by the introduction or 

 adoption of machinery. This plane is largely used for 

 cutting trenches across the grain of the wood to weaken it 

 for bending, as in the instance of circular casings to doors 

 and windows. See " Plane."

 upper floor.

 knife is bevelled to give a shearing cut. It is used to trim 

 off the end of a piece of wood by moving the knife by a hand 

 lever or self-acting motion across the wood. By means of 

 swivelling fences, mitres and angles may be truly cut.

 ming " and " Float,"
