Abstract

2090. Bullows, W. L. Jan. 30. Swivels.-A swivel adaptable for traces, chains, hooks, tightening-screws, &c. is made by bending a piece of iron rod to form an eye a, and by welding the two ends brought together. Over the stem, a loose collar b is placed, and a head c rather less in diameter than the collar is formed on the end of the stem. A short piece of tube d, which just passes over the collar b, is flattened at one end and pierced to form an eye e, Fig. 6. The head c and collar b of the eye-bolt are inserted in the tube d, and the end of the tube is hammered or welded over the collar b, so that the collar is held firm while the eye-bolt may revolve freely. Two eyebolts may be fixed in a single piece of tube as in Fig. 8, which shows the invention as applied to a trace end swivel. One of the two eye-bolts may be without a loose collar, the head of the bolt being fixed in the enclosing-tube. A spring swivel is constructed by lengthening the stem of the eyebolt, and surrounding it with a coil spring between the head c and the collar b. A tightening-screw, Fig. 9, is constructed by replacing one eye-bolt by a screw bolt f passing through the end of the tube d.
