uprights, preferably at right angles with the platform: from these uprights are
suspended trays, these trays suspended as retain their vertical position, at what-
ever angle the platform may be inclined. The platform reversed the trays are
suspended below such platform-reinstated the trays are brought over the obverse
surface of platform-the trays and contents retaining their vertical & normal
