This invention relates to ladders and more par
ticularly to a ladder of the step-ladder type, it
being one object of the invention to provide a
ladder with supporting legs at its rear which are
mounted for swinging movement toward and
away from the ladder into and out of folded po
sition or into extended position for propping the
ladder in upright position for use, the props or

they will very effectively hold the legs extended.
Transverse movement of the legs to extended
position is controlled by a stretcher structure
shown in Figs. 2 and 3. This brace or stretcher
consists of strips o1- bars 33 and 34 pivoted to
front and rear faces of the legs by pins >35. The
inner ends of the bars are overlapped and piv

sleeve 31 and one of the bars 34 is provided at its
inner end with a tongue 31 extending longitudi
