contraption
1.I don't understand how this contraption works.
2.It was a noisy contraption unlike the modern machines you see these days devouring the golden armies of grain in wide gulps.
3.Walking to work one morning last fall, I happened to notice an odd gray contraption fastened to a streetlight on Madison Avenue.
4.The transistor, dating from 1947, has shrunk from a kludgy, half-inch-high contraption to a device whose components boast dimensions a few hundreds of atoms in length.
