now Patent 2,379,788, patented July 3, 1945.
An object of this invention is to provide a novel
type of folding ironer cabinet, the sides of which
become working shelves for the ironer when the
cabinet‘is'unfolded.

Another object of‘ this invention is to provide
a folding cabinet‘ for an ironer or the like, which
folds into a package having relatively small hori
zontal extent, thus. being particularly useful
where floor space is at a premium.
Further objects and advantages of the present
invention will be apparent from the following de
scription, reference being had to the accompany
ing drawings wherein a preferred form of the,
present invention is clearly shown.
