narily consisted of a door panel hung from an
overhead track by means of several spaced rollers,
and adapted to be slid into a central housing
space provided in the wall adjoining the door‘
opening. In some instances, the overhead guide
tracks were formed directly on the wooden head
jambs or door headers, but the suspension rollers
which coacted with these tracks and the hangers
which united the rollers with the door panel, were
universally formed of metal such as die castings.
The material from which these die castings were
made has become di?icult to obtain, and the same

These and other objects and advantages of this
