To ad whom 'it may concern:

Be it known that I, ROBERT J. BROWN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certa-in new and useful Im rovements in `Fire.Escapes, of

ollowing is a specification. l

s, and

This invention relatesto-iire-esca y for lthe is particularly intended and ada te escape of persons who are unab e t0 ally control or el'ecttheir. own escape by means of ropes, ladders and similar devices which require more or less strength, judgment and agility for their successful use. 15

is therefore articularly useful on schools', hos itals' and) the like; but it may also be comprises essentially a s yiral concave chute accessible from the wimws or doors of the various stories of the building to'which the device is appliedythe chute being supported partly by the buildin and partly by standards erectedb'eside Vthe uilding.

The invention is illustrated in .the accompanymg drawings, in which Figure ll is a pers ective View thereof; Fig. 2 is a section'on tie line 2-2 of Fig. l. Fig. 3 is a section through the bottom portion of the chute.

, Figads a sectional view at one ofthe `win-- dows of the building.

Refcrringspeciiicully to the drawings, the supporting framework is built Of six pairs of standards A, of angle iron, Secnrel y cemented into concrete piers in the groun strength and firmness being secured by sufficient braces B, and the standards are braced at the top by the parallel spiral iron su port rails one on either sidefwiich complete the framework. This framework carries a concave spiral chute C which .is nia/de riveted, so that one section overlapsthe next section ment to descent. The troug convenientlv be about 'thirty twoinches from rail il- ,;'ail, and twenty inches deep at the middle. These measurements are tentative. This chutestarts freni theflower sill of the upermost story window, to the ca'sich the rails are fastened, lcs'cen'rb Illanll- Vwhereby access below, thus causing n'oimpedi4` h or chute may' y ing as a spiral, and the descent should 'not exceed about twenty two or twenty three degrees, completing ,the circle in one rstory and reaching the sill or projecting latform of the next story window below w ere the chute hiis Wings or extensions W fastened to the window casing, scending, meeting each consecutive window, to the ground. This spiral chute continues uniformly to a oint where it brings the supportin rails, three feet of'tie ground surface, where the chute turns up to the horizontal, gradually losing the concave shape until mergeljl` into a il'at surface M 'at the end of the rails R, which forms a platform or sto The platform or- Hat surface complete y overcomes themomentumof the descending body and brings the'object or person` to' acomplete stlp thereon. f

n use the 'persons esca ing will simply ste 'out of the windows and' 4 an' willvslide down to the lower platform without danger of falling, noskll or manipuf lation being required, and hence it maybe used with safety even by small children, the insane, or invalids. lThe cost ofconstr`uc-` tion is not great, and itis always available for the intended purpose. Y."

I claimz A fire-escape com prisin ing standards with cross the same, a metallic chute to within two orr and sovcontinuously desite side rails fastenedto the Standarda-'and n concave sheet metal sections secured at' tlei'r side edges tothe rails, thechute -being s 'gral in form -and curved to completea clree'. in each storyand havingrecessesf in thc'side thereof with the' building adjacent openings. ,therein, from each successive story-is permitted, and a stop at the bottom of the chute; 4.

.In testimony whereof, I affix my. Vsignature in presence of two witnesses.`
