Fig. 2601.
[Fig. 2601] represents a hanger of this class. In this the lower part carrying the bottom bearing is held to the upper by two bolts, as shown, the object being to enable the same to be placed in position on a line of shafting without disturbing the pulleys or the couplings. The lower section with the bottom bearing is removed and again put on after the hanger is set over the shaft.
Fig. 2602.
[Fig. 2602] represents an open-sided ball-and-socket hanger in which the plungers can be retired, the bearings removed, and the hanger erected on an existing line of shafting without removing the pulleys or couplings, or disturbing the line of shafting.
Fig. 2603.
When the face of the framing to which the hangers are to be bolted stands vertical, the hangers are formed as in [Fig. 2603], in which the ball-and-socket or swivelling feature is maintained as before.
