. a type intended more particularly 'for application asn {ire-escape and Ain such use would be attached to the Wall of the building in front of or adjacent to a verticai row of windows or other openin sthereof and in connection with suitable lan ings, such as ordinarily employed with fire-escapes now in use, will afford a ready means |oi escape from the building.

It is Well known that the fire-escapes now usually employed are unsightly and greatly detract from the artistic appearance of the building especially,as is fre uentl the case,

when the fire-escape is place on t ie front of the building. y

it is the general object of my invention to provide a ladder for use as a fire-escape which y reason of its small transverse area will scarcel be noticed when applied to the build ing an the size and character of which wiii permit me to empio landings much smaller than those now usua ly employed.

The ladder may even be made to add to the architectural beauty of the budding, as owing to its eculiar shape or sinuons outline it readily ends itself to combination in various architectural schemes. The artistic appearance ma be further increased by constructing the laddenof brass or plating the same with nichel or other metal or suitably painting the same. y

Owing toits ineonspicuousness when applied to a budding, my improved ladder may e used as an auxiliary fire-escape, if desiredthat is to say, the fire-escape now used may be employed and my improvement be located at various oi nts about the building, and thus afford additional means of escape therefrom in the event of a fire.

In the accompanying drawings l have illustrated an embodiment of the invention; but it is contemplated as within the scope of my invention to vary the outline or configuration of the ladder from the form shown.

Referring new to thedrawings, Fi'ure 1 is a view in front elevation of a ladder constructed according to my invention and connected to a suitable structure,A shown conventionally. Fig, 2 is a View in side elevation curved outwardly,

of the same, and Fig. 3 is an enlarged detail showing one of the sections ofthe ladder.

As shown by the drawin s, the ladder as a whole is made up of severa sections 1, which are connected together by being screwed one into the other, as indicated at 2. The sections 1 when so joined together provide theiadder, which comprises a series o steps being for the right foot and the steps 4 for the left foot. Between each of the steps 3 and 4 is provided a handheld 5, said handholds being in vertical alinement, or substantially so, throughout the length of the ladder. The metal at one end of each handheld is first as indicated at 6, and

then horizontall inward an equal-distance beyond the me ian line of the handheld toconnect to the reversely'curved portion 7, extending fromV the bottom of the adjacent handheld, so that the art of the ladder between the two handho ds has the shape substantiaiy of the letter S. As the curved portion 6 and the curved portion 7 aiternately extend throughout the ladder in diametrically opposite directions, the result will be that the opening or recess 8, formed by the curved member 7, will alternately o en on diametrically-op osite sides of the la der, so as to provide rig t and left ootholds. The

Vhorizontal portions connecting the curved members and 7 form, of course, the steps 3 and 4,

In Fig. 3 Ihave shown a section as compris- Yin at op osito ends the haines of two handho ds Wit two steps and an interposed handhold between them. It will be apparent, however, that each section maycom rise two, three, or more'handholds, as may be ound desirable in the manufacture of the same.

The ladder may be composed of tubular metal, or the sections may be of solid material. By preference the handhelds 5 are gradeeiiy enlarged form their ends to the center in order to facilitate the grip of the hand'thereon, as will be understood.

The ladder as a'whole is connected to the house by means of main supports 9 and auxiliary sup erts 10, secured in or to the wall of the bui dingV and connected to the ladder at various points, preferably beneath the handholds 5. The outer ends of the sections at the opposite ends of the ladder are bent inward at right angles and then curved upon themseives to form heart-shaped braces 11,which bear against the wall and serve 'to securely support and brace the ladder by means of steps 3 and 4, the

IIO

cured to thc under sideof the eaves of the house or to any other suitable proj ectin g part.

I' desired, l may cover the steps 3 and 4 and the handhelds 5 with rubber, leather', or other material.

lt will be a )parent to tlicse skilled in the art that iny ladder will be useful in man other connections than as a iire-escsipcor instance, it may be enjiploycd on signal-towers, telegraph-poles freiqht cars, battle ships, chimneys, and the li c.

Iclaim-m 1. A metallic ladder' comprising a single se ries of connected verticall r-disposcd and alin ing handholds, the metall between eachtwo adJacent handholds being d isposed outwardly on o posite sides of the longitudinal axis and in a ternatcly reverse directions throughout the length of the ladder to afford right and left foothclds.

2. A metallic ladder comprising a sin le series of connected verticall -disposed an alining handhelds, the meta between adjacent handholds being bent outwardly in opposite directions to produce horizontal footholds l which project beyond op )osite sides of the vertica plane of said hand iolds.

3. A metallic ladder formed as a continu ous structure and comprising a unitary bar of metal. bent outwardly upon itself in two opposite directions at different points and at ceases suitable intervals throu hout its length to provide horizontal mem ers, rentrant or tions which are oppositely-disposed in a ternation, and an intermediate straiirht portion.

4. A metallic ladder comprising a single series of connected vertically-disposed alining handhelds, thc metal between adjacent handholds being disposed outwardly on o posite sides o the longitudinal axis to provi o footholds.

5. A metallic ladder comprising a continuous len rth. of material presenting a series of handho ds in vertical alinelnent and between the ends of adjacent handhelds being zig- Zagged to provide a foothold, the center of each of which is substantially in line with the longitudinal axes of the handholds.

6. A metallic ladder comprisin a continuous structure presenting a series o handhelds in vertical alineinent and between the ends of adjacent handhelds `heilig zigzagged to provide a foothold, the center of each of whiohis in line with the lon itudinal axes of the handholds, said footho ds alternating from right to left throughout the len th ofthe ladder.

In testimony whereof have hereunto set niy hand in presence of two subscribing wit- EUGENE V. LYNCH.
