This application is a division of my copending Fig. 15 is an enlarged vertical cross-sectional view taken along the line l5-—l5 of Fig. 1; Fig. 16 is a horizontal cross-sectional- view taken along the line I 6-46 of Fig. 17; Fig. 17 is a View taken along the line ll.'i—l1 of Fig. 1, also on enlarged scale; Fig. 18' is a horizontal cross-section taken along the line l'8—|8 of Fig. 4, one corner only being application Serial No. 209,227, ?led May 21, 1938, 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. shown; 10 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. ‘ In the drawings: Fig. 1 is a perspective view of one form of the Fig. 19 is a vertical cross-section taken along the line l9—l9 of Fig. 15; Fig. >20'is an enlarged top View of a corner of the table top 1'; ' Fig. 21 is a cross-section taken along the line 25-21 of Fig. 20; Fig. 22 is an enlarged view of an upper corner of leg ‘I; Fig. 23 is a top View of Fig. 22; and Fig. 24 is a horizontal cross-section taken along 20 the line 24-24 of Figs. 8 and 10.
