essa-ESCAPE.

sPEc'IFIcATIoN forming-Ratt 0f Letters V tmllliS-ni l l To all whom it may concern Be itknown that LSAMUEL T. MICKEY,4

a citizen ofthe United States, residing at Mount Airyfinthe county of Surry and State of North Carolina, have invented new and useful Improvements in Fire-Escapes,of-which the followingis a specification.

My invention relates to an extension towerlike tire-escape having an inclosed passage from top to bottom, its object being to provide for the extension of an escape-ladder therein simultaneously with the raising of the tower for stowing the ladderin convenient position and condition for subsequent use as the tower is lowered, and to prevent the severai sections from becoming separated `when extended.

.In the drawings, Figure l is a perspective view of my improved fire-escape apparatus sections section taken on a vertical plane indicated by dotted line .fr fr, Fig.,1, the seclions being raised. Fig. 3 is a side elevation of one of the sections with the door lowered and extended, and Fig. 4 is a section taken on a vertical plane indicated by the dotted line y y, Fig. 1.

The letter A refers to a platform for supporting my improved tire-escape apparatus. This platform is supported by wheels B, and it is otherwise adapted'to admit of the apparatus beinglrreadily drawn through the ot' a cityLuThe lower-outer:; section, 0,-of the series of telescoping sections in this apparatus is secured upon the aforesaid platform A,'and is constructed substantially. in the form of a rectangular box with closed sides and an open top; or in lieu of'the solid priat'e frame-work may bee'mployed for all of ich is designed to face the bnilding. The material of which this section is composed is preferably of metal, although a portion ofthe section might be constructed of wood anda portion of' sheet metal, or of wood protected by sheet metel. in order that' when the apparatus is drawn up which faces the tire will be closed and made non-combustible, both for the pur-pose of 'pretaking fire and for shielding persons-ascending or descending within the same from smoke, sparks, and

streets of`a burning building/'that side of it- Patent No;

236,348. dated Janna-W4, 1881'.

Haines issuing out from the windows of 'the burning buildings The section C'is provided with a door through one of its sides,` so that persons may pass in or out thereof. AThe remaining sections D E -F are preferably constructed in a similar manner to thesection just described, and are arranged to telescope structure may be contracted in compact form, so as to pass through the door ot' the engine- 4house and under telegrapl1wires, elevated railways, and bridges. The height and Inurnber of these sections will be according tothe height 'to which-it is adjudged necessary to extend 'the apparatus.

The lower section,

persons; andthe upper section, F, has door F', which is hinged at its bottom edge, so that -after thefappa'ratus has 'eedb'rght alongside of'a building l so as to bring the door ot' a level with thel window, of the building to which access is desired, the hinged door of said top.;secti0n. can be let down, so as to form a bridge ,between the apparatus and Lthe building.

vided with a movable egitensionfFso that the bridge which will be formed vby the door 'when lowered may be extended with reference to the space between the apparatus and 'the building; and as a convenient means for operating such extension a cord, F 3, is con- 'nected with the same and passed around or through suitable guides G, in'such manner that by drawing the cord in one direction the extension will be moved out, and by drawing upon the cord vin a reverse direction the extension will be retracted. This cord is also to `be utilized for the ing the door,- as'occasion may-require.`

The section() has anges c projecting iuwardly from the tops of" two of its opposite sides, and under these tlan ges extend a-nges d projectin g outwardly from the bottom edges the upper section ou section has top anges, d, under which take section is also provided with top flanges, e,

lor slidewithin each other, 4in order that the f 6o and the sectionsextended vThis doon is proof two ofthe opposite sides of section D,which bottom flanges, e', of section E, and this latter..

C, is .provided withi a door, C',A to admit of the entrance and exit ot' l or such-other portion l'C under which project bottom auges, f, of the top section, F. The flanges of the severalsections, by theirinterlocking,'prevent said sections from moving outward too far and becoming disengaged from each other, and they also act as guides when the upper sections are moving.

The devices employed for raising or lowering these telescoping sections are as follows:

Within the lower section, C, is arranged a rotary drum, H, which is operated bya crank,

H', at one of the outer sides of saidl section, and to this drum are fastened twocords or chains, I I, which pass up and over pulleys K, upported in the inner ,walls of section C,

' an 4thence -down to ',a horizontal. bar, L, .se-l

cured in thelower portion of the next upper scction, D. Within the lower portion ofthe lower section, C, is arranged a. bar,M, from which' two cords, M', pass upward and over pulleys N upon the inner walls of the section D, and thence down to the lower portionof .the next upper section, E, where they are secured; 'and V from the lower section,. and that simultaneously with said movement of the second section D the remaining upper sections will, of necessity, bel raised by reason of the cordconnections between the sections, 1t willl also be seen that but o'ne rotary drain is required t effect thisoperation, and that where more telescoping sections are employed than Ihave herein illustrated each additional section can be made to operate in a similar manner.A A

ln order tovoheck the drum-'from rotating so as to' unwind the cords or chains therefrom after the sections have been raised toa proper height, any suitable stopmechanism lmay be employed-as, for instance, a rod, Q, may be passed through the lower section in such manner that by sliding'` the rod in one direction one o t' its ends will extend out from the said section so as to engage the` handle of the drum, or a'ratchet-wheeh may be secured upon the shaft of the drum and a pawl arranged to engage with the ratchet.

The means employed for permitting the ascent or thel descent of persons through the several telescoping sections consistof a ilexvihle,ladtderglt` secnredlit its tn pJmd txrascrossna nar, lt', in the upper section, F, and connected at its lower end with awindlass, S, located within the-lower portion of the lowest section, C. The shaft ofthis windla ss extends through one of the sides of this section, and is provided with a crank-handle, S', by means of which the windlass can be operated to reel up the ladder upon the windlass. As tho several telescoping sectionslare raised.I by the means just described the flexible ladder .will be unreeled from the windlass in proportion to the height to which the top section of the apparatus is elevated, and when 1it is-desired to'retract or lower these sections it will only be necessary tov turn the windlass so as. to reel lup the ladder, a'nd thereby draw down the top section, the remaining sections following, as a matter of course, such movement of the vtop section. It is, of course, understood .that in lowering the section s Athe stop or bralieis taken off the drum and the latter turned so as to unwind the cords or chains-thereonaand as a means of guarding against thetoovrapid rotation of the drum, which would be occa-I sioned by the weight o f the descending sec'-l tions upon the cords, a brake-lever, T, is arranged to be applied to the shaft ofthe drum with such force as may be found necessary.

To provide additional means. for steadying the apparatus while in an extendedstate, and also to assist in drawing ldownv the top section shouldsuch assistance be rendered necessary, I provide upon the platform A two shafts, U, with -crank handles U', shafts or r trs extend cords W upto glie, top corners of he upper section of the apparatus. These cords will be unwound from the shafts as the sections are raised.

From the above it will be readily understood that my improved {ire-escape apparatus canbe readily extended to any desired height, and that a safe and agreeable passage will bef thereby provided between the ground Vand the windows o'rroof of a building. f

This apparatus, while providing lne'aus -for -the escape ofpersons from thebuilding, is

also especially adapted as a' tiremans ladder, and by providing more than one of the sectins with the extension-doors access can be easily had to different stories ofthe same building while' the apparatus remains in an extended state. Having thus described my invention, what I claim is `1. The combination, with the telescoping sections in a fire-escape apparatus, of a ilexible ladder connected at vits upper endl with the top section, and at its lower end attached to a windlass arranged within the `lowest section, substantially as described. A v

2. The combination of the. telescopic sectionsprovided with the top and bottom dan ges, serving as guides and stops, fen Y 1 v said sections one fromv anot er.

In testimony whereof l have hereunto set my hand in the presence of two subscribing witnesses.
