Handy Blacksmiths HoistingSwivel. A handy hoisting swivel for heavywork is in the blacksmiths shop of thenew Pennsylvania Railroad, at Wilming-ton, Del. The swivel hangs from an or-dinary hammer crane and the end of thetop link is upset and a heavy squarethread is cut on it. The top one is aright hand thread and turns in a nut,from which two stout handles hangdown. The handles are like those of a. |H—ChaiM Bi/. i Loco. I> SWIVEL. loving cup turned upside down. The low-er nut turns on a left hand thread, alsoupset, and from the bottom of this lowerlink of the whole system hangs a pulleyand chain which supports the free endof the work when on the forge. The reason the handles hang downbelow the level of the lower nut is thefacility which the arrangement gives tothe smith or his helper to grasp theswivel at convenient height and raise orlower the free end of frame or bar aspart of it lies in the forge fire. The han-dles are made strong enough to carrythe weight, notwithstanding their curvedform, and the ends of the two links, aswe have called the top and bottom bars,are upset so that larger and coarserthreads may be used, thus in- creasing the lift or fall for everyturn of the swivel. The arrange-ment does not take up much roomand does away with the dangling chains
