FIRE-ESCAPE.

Application led November 15, 1907.

To all whom 'it may concern:

5e it known that i, JAMES C. COVERT, a citizen of the United States, residing at N atervliet, in the county of Albany and State of New York, have invented certain new and useful Improvements in Fire -llscapes, of which the following is a specification, reference being had therein to the accompanying drawing.

rThe invention relates to an improvement in fire escapes and more particularly to that type designed as a permanent fixture for a building. ,ln this class of iire escapes, for reasons well understood it is desirable that provision be made for normally maintaining in an elevated position the lower portion of the device, generally that portion thereof adapted to extend from the second story of a building to the ground.

The present invention in its broadest sense comprehends a collapsible ladder member permanently connected at one end to a support at a point some distance above the ground to extend from said support to the ground, said member being adapted to be arranged and supported in a collapsed or folded position adjacent said support.

More specifically stated the invention comprehends the use of such a collapsible ladder member to constitute a direct continuation of another ladder member secured to a building.

One of the chief aims of the invention is to provide a simple arrangement, whereby the collapsible member when held supported in a folded state, may be conveniently released and positively opened or distended by applying pressure directly to said member.

@ther novel features of the invention reside in the particular construction and arrangement of parts before referred to and in the special construction and location of the means to hold the collapsible ladder member in its folded state.

llt/Vith these and other objects in view, which will appear from the annexed detailed description, one embodiment of the invention comprises the construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and pointed out in the appended claims.

ln the drawings: Figure l is an elevation of the attachment showing parts of the hXed portion of the ladder and parts of the building, Fig. 2 is a side elevation showing parts in section and the extension in a folded condi- Specieation of Letters Patent.

tion, Fig. 3 is a detailed perspective view of the clip and its bracket attachment, and Fig. l is a side elevation of a portion of the collapsible ladder member showing the position of the parts when extended.

Referring to the drawings in detail, wherein like reference characters designate corresponding parts throughout the several views, 1 designates a portion of the face of a building or other structure and 2 designates a ladder member structure shown in the present instance as rigidly secured thereto and terminating some distance above the ground floor thereof. A collapsible ladder member 3 is permanently connected with the ladder 2 to forni a direct continuation of said ladder to the ground. rlhis member 3 is made up of a plurality of rigid sections in the nature of links of substantially U-shape form, the sections having a hinge connection with each other and the upper terminal section having a hinge connection with the lower rung of the ladder member 2, so that said sections are adapted to extend in the vertical plane of the rungs of the ladder section 2. The member 3 is adapt-ed to be so arranged and supported in a collapsed or folded state at the lower end of the ladder member 2, that a person mounteden said ladder may, through the medium of his foot, conveniently apply pressure to the member 3 to release and positively open or distend said member. Vilith this idea in view, the sections of the member 3 are adapted to be folded up one upon another in a pack at the lower end of the ladder 2, the upper surface of the pack of sections extending substantially parallel with the lower rung of the ladder 2 and to the front of the vertical plane of the rungs of said ladder, the position of the upper terminal section of the member 3 being unchanged except that it is swung inwardly toward the wall l and the lower terminal section lying at the front of the pack.

The means for supporting the member 3 in its folded state comprises a catch connected to the wall 1 and a bail pivoted to the lower terminal section of the member 3. rhe bail has side portions 4t and a forward narrowed nose portion 5 arranged at an angle to project within the pack of sections when the bail is folded down against the lower terminal section, the portions lof the bail lying against said section and serving to limit the extent of inward projection of the nose portion 5 within the pack of sections. The

catch, Whichis made up ol two flat strips of metal 6, 7, placed lace to lace and secured together at one end and shaped to lorrn spring jaws, is supported by a bracket 8 secured to Y the wall so that the aws thereol' extend within the pack ol' sections su'lliciently to receive and hold the nose portion 5 oi the bail, and when the parts have been thus engaged, the member 3 will be securely held in its folded state asV indicated in Fie. 2 ol' the drawingsA The connection o'l the catch with. its supporting` bracket is as follows: The strip 6 oli' the catch is extended above the upper end ol' the u strip 7 and near its upper end is cut away at opposite edges to provide a reduced Vportion 9 with shoulders 10 and 11 at the upper and lower ends thereof respectively. The reduced portion 9 loosely nts within the socket 120i' the bracket, the shoulders 10 resting V upon the upper edge ol' the metal `forming the socket. The upper end ol'l the strip 6 l'rom the lower' end of the reduced portion is curved and the lower l'ront wall ol the socket is slotted at 13, the lower edges of the side walls ot the socket being beveled to cooperate with the shoulders 11.

; As will be understood, when the collapsible member 3 is arranged and supported as illustrated in Fig. 2 of Lhe drawings,the same may be easily and quickly released and positively opened or distended by applying pressure thereto, the pack ol sections pivoting outwardly on the transverse portion ol` the upper terminal section. As soon as the sections have been Vl'orced outwardly sulliciently to disengage the bail l'rom the catch, the catch will drop back to its normal position close to the wall 1.

It may in some cases be desirable to provide the Aflexible section with projections to rest against the wall so as to hold the extensions out lrom the wall when it is dropped down. This is accomplished by l'orming the extensions 15 on'the eye part ol the sections as shown in Fig. 4. Any number ol' these extensions 15 may be employed but prelerably `every alternate lrame should be so provided. A convenient manner of forming the extensions is shown in my l'ormer patent No. 793,770 ol' July 4, 1905.

I desire it to be understood that various changes, within the scope oil` the appended claims, may be made in the construction and arrangement 0l parts hereinbe'l'ore set 'l'orth without departing from the spirit or sacrilicing any of the advantages ol the invention.
