Be it known'that I, ALBERT H. Looms, a citizen of the United States, residing at Ravenna, in the county of Portage and State of Ohio, have invented certain new by means of eyes 9 produced .at the top or and useful Improvements in Ladders, of which the following is a s ecification.
This invention is a exible ladder particularly adapted for use as a fire-escape, being conveniently made of light metal rods, in sections connected one to anotheraud capable of being folded together, so as to occupy littlespace when not in use. The
ladder may be made in several parts which by means of snap hooks can be united to make a complete ladder of length. This will be convenient in high buildings, allowin the various parts, quickly 'ut enabling them to be out from the building be let down close be or foot pieces project at each ste so it can side a lJUllL ing it necessary, affording at such time good footholds.

the rods and preferably closed by welding around inwardly ofl'set portions connecting the'si'de pieces to the inner ends of the outwardly extending parts-'8. The eyes large enough to roduce sufficient -flexibility to allow the la der to be folded to small r compass, for convenient' storage.
-The ladder, especially for use in high buildings,-is referably made in several parts or lengths w ich may be quickly united on occasion by snap hooks 10 connected to the eyes at the top of the side ieces and adapted to engage the offsets 8 of t e length above.
In case of fire the ladder can be quickly let out of a window, uniting several -lengths if necessary, and then used for the intended purpose.
' I claim: I
A ladder comprisingseveral sections each consisting of a rod bent to form side pieces with eyes at the upper en inwardly oiiset portions at the lower ends or ale pieces and an outwardly o'liset cross piece at the inner ends of said portions, the eyes extending around said inwardly offset portions to unite the sections.
In testimony whereof, I ailnr my signature in presence of two witnesses.
