SPECIFICATION" forming part of Letters Patent No. 283,008, dated August 14, 1883.

Application filed February 8, 1883. (N0 model.)

To all whom it may concern: A Be it known that 1, CHARLES T. MERRITT, a citizen of the United States, and residing in Hyde Park, in the county of Cook and State ful Improvements in Fire-Escape Ladders, of which the following is a specification.

The object of my invention is a fire-escape ladder which does not render the exterior of a building unsightly, and which, by folding, as herein described, will not occupy space designed for other purposes, and which will afford to occupants of abuilding as easy ameans of escape as a stationary ladder. Theladder may be made of wood, iron, or other suitable material, and is constructed in sections of two or more rounds each, the top section of the extended ladder being the larger, and each succeeding section being smaller until a new series of sections is advisable. These sections are joined together by bolts, and when the ladder is not in use the smaller sections may be folded within the preceding 16 rger one, and thus several feet of the ladder when folded will only occupy the space of the first or larger When anew series of sections is deemedadvisable, the succeeding sections may in turn be foldeclwithin the first section ofthat series. The ladder is fastened by chains to the bottom of a box of proper size, fixed in when not in use may be folded within the box. In the drawings, Figure 1 represents a front the ladder being made of three series of four Fig. 3, the vertical projection, showing the sections of the ladder; Fig. 4, a horizontal proshowing ladder folded in it, lid of the box open and broken off to save space Fig. 6, a top view of the box open with ladder folded within; Fig. 7, a side view of another form for the projection connecting the series of the sections; Fig. 8, a horizontalview of the same.

Similar letters refer to similar parts through out the several views.

a to represent the chains to which the ladder is attached; I), the box in which the ladder can be folded d d, the projections connecting different series of the sections; was, the section connecting c and c, as shown in Figs. 7

and 8- c c c c sections of the series; 6 c e e bolts which join the sections; A, the sill inside the window; 0, the window-frame; D, the outside sill; XV, the wall in which thebox b is placed. enough,the box may be placed in such a position that the sides of the ladder when folded will lie at right angles to the window, so that the ladder will more readily unfold. The projection (Z is only needed at the sections where anew series is deemed advisable, and should project, so as to allow 0 to fold over 0, as shown in Fig. 5. I11 Figs. 7 and 8, I connect the series of sections by means of the sections m a;,'which are connected to the sides of the section 0* by bolts, while the rod connecting the sides of the section 0 passes through the sections a" a. A shoulder should be made in the rod connecting the sides of the section Where the inside sill is wide c so'that the connecting sections a: mwill not sides of the section, and the rounds of the third section as in the first section, &c., as shown in the drawings, Figs. 1 and 2. I

By constructing the ladder in the manner shown it willreadily fold, and the sections 0",

c", and 0* will fold within a, and the next series of sections within 0". WVhen the ladder is folded in the box at right angles to the window, it may be lifted from the box in sections, and a rope may be'attach ed to the lower round, so that it may be fastened.

Having fully described my invention, what I desire to claim and secure by- Letters Patent 1S.-

1. A ladder consisting of a series of sections of one or more rounds each, so constructed that the section 0" will fold within c 0 within 0 and 0 within 0, 0 being connected with the next series of sections by the sections w 00 or the horizontal projection d, substanwithin 0, 0" Within 0, 850., said ladder being to tially as shown and described. fastened by chains to the bottom of the box in 2. A fire-escape ladder made in a series of which it may be folded, substantially asset sections, the rounds of the ladder of each secforth and described. tion being on o posite' sides from the reced- 5 ing section so gonstructed that the se tion c CHARLES MERRITT' will fold within 0 0 within 0 and 0* within Vitnesses: c, and by means of the connecting sections 00 x CALVIN DEXVOLF, the section 0 will fold over 0, a being folded WVA'LLAOE L.
