The pivot is fixed on the frame, and the vibration produced by thecrank is multiplied at the other end of the spring lever, so that strong, rapid blows are given bythe hammer. In Fig. 1384 is shown a kind of composite machine, half trip hammer, half crankhammer. The helve and radial die movement are retained, but the hammer is operated by a crank,through what is in substance an elastic connection. Such hammers as these here described ar^well adapted for light work and small pieces, as on account o
