DEFINITION

Classification: 24/427

Having specific contour or arrangement of converging channel, separator island, or wing:

(under subclass 415) Sliding device including specific details of either the shape of or the assembled relationship between (a) a channel portion of the sliding device having converging walls which partially encompass and force together the interlocking surfaces when the sliding device travels in one direction, (b) a wedging portion of the sliding device which pushes between and forces apart the interlocking surfaces when the device travels in the opposite direction, or (c) a wall portion of the sliding device which supports the channel and wedging portions and restrains the outward movement of the interlocking surfaces within a fixed bounded region for alignment purposes.
