It usually consists of a box or chamber, made by an enlargement of part of the hole, forming a space around the rod or shaft for containing packing which is compressed and made to fill the space closely by means of a sleeve, called the gland, which fits loosely around the rod, and is pressed upon the packing by bolts or other means.
