Fig. 2604.
[Fig. 2604] represents a wall hanger, which is open in front similar to the hanger shown in [Fig. 2602], and for the same purpose.
The section of shafting receiving power from the engine or prime mover is usually supported in bearings or pillow blocks. Pillow blocks are also used for vertical shafts, and in cases where the foundation or framing is not liable to lose correct horizontal adjustment.
Fig. 2605.
[Fig. 2605] represents a pillow block, in which the ball-and-socket principle shown in [Fig. 2602] is embodied. The bearings have each a ball section fitting into spherical recesses or cups provided in the body of the block, and in the cap, so that the bearings are capable of swivelling as already described with reference to the hanger [Fig. 2599].
