from The Century Dictionary and Cyclopedia
- n. Any material used to pack or make tight the space between the perimeter of a piston-head and the interior of the cylinder or-barrel in which it moves.
- n. A mechanical device for packing pistons, in which the operation depends more upon the construction than upon the fibrous, plastic, or compressible properties of the packing-material.
Sorry, no etymologies found.
The new pipe-condenser did not work well, the cylinder was almost useless, having been badly cast, and the old difficulty in keeping the piston-packing tight remained.
