pillow block

The cord or line is set true to the cylinder bore, and coincident with the centre of the pillow block, as at a a in Fig.

Draw these views properly projected from one another, showing the pillow block, which is to be proportioned by the rules given on page 32.

It is supported at a distance of one meter from the floor by four pillow blocks, and is formed of three sections united by movable coupling boxes.

A loose pillow block box is a good "knocker."

The main pillow block has a base 6½ feet long by 21 inches bearing, weighing 2,800 pounds.
