STATES' l ninunrL.' Fien, or serrano, New YORK.

Be it'known'that I, HENRY L, lFIs'H, a

citizen of-the United States, residing at Buffalo,` inthe county of Erie Vand Stateof New York, have invented certain new and useful )Improvements in Firep'roof Shutters.,

Curtains, or Similar Articles, of` which the following is a specification.

This invention relates A'to automaticallyoperated or self-closing. shutters `or-doors, and itv consists of a shutter or door composed of a plurality of metal plates, so vconnected and arranged as to permitoftheir being folded in-.colnpact form Within 'a -suitable -hood or.. housing, and upon being released will drop by gravity, thus closing the open inor over which the are placed.' -Ihe' invention.. urther consists' of -a suitable l device for supprtin' the sectional shutter or door 1in its closed',l or folded Aposition, and fusible means for holding thesupportiin 'normal position. f Thel invention still further consists of the novel construction and arrangement of thez5lv several parts, as will be hereinafter fully described in this specification an'djbriefiy 4otherwise defacin i, position Within the jhood'or housing; Fiif, roor' stated' in the claims. l

Oneof the Vprime objects of the invention is tov roduce-a fireroof shutter or door, of

the c aracterfdescn ed that` can be readily attached to aybuilding 'without cutting or the same, and neither; occupvaluabe s ace nor shutting out air :or'li t. MThisgan other objects are attained y means of the mechanism illusfinthe'faccompanying drawing,y in;

vis entirelA prevented, j When the sections of the shutter are in .their normal position, folded Within the hood or housing, they are supported in such ,osition by an arrangement of hooks or l evers 24 and 25, lever 24 being hinged to an 'rear-26, attached to the lian e '14, atthe center, and the lever 25 being inged to an ear en 25126,- by a fusible link 28.

The free end of the lever 24, is f portedupon the lever25, and the free of the-lever 25, is connected to the ejar The operation of the device will be obviousl from the' above descri tion, it only being necessary to state that he link 28, becomin fused, the vsup orting .levers will drop, an the shutter or oor being' released, will automatically'v drop, its'descent being facilitated and rendered more positive by the additers, and the like, have eenrmade, the-slats vtional Aweight of the bolts or rods, connecting "the lower sections to the upper' section.

I am aware-that fire roof curtains, shutor sections of Whichare adapted to slide over each other upon rislng, having as gulde sec.- tions a slotted portion on one slat or section,

suchconstruction leaves slotted openingsm- 'the guide sections or slats of the shutter or dust, dirt and rust in the slot,- whch increases i frictionand hinders the rapid closing of the shutter by gravity when thevretainjng device -which maintains thegshutterina normally folded condition, is released. r In the present invention it will befseen that such objection and dilliulty iS avoided as the sections or slats. travel on guide bolts .or similar devices, arranged' to operate and depend at er1-angle to a er ,endiculan in an upward and downwardirection, on folding or extending the curtain, and the sleeve 'or thimble which travels upon and i; over said guide Y' bolt contacts with the 'said guide bolt, at

a point or on va line only in Ycontradistinction to and from the broad surface contact found in .devices of the V prior art.

.or sleevepwhich travels onf the guide bolts 'is also provided with or pompos'ed of an 65.- anti-friction substance or rrfiaterial to admit'- the least lpossible resistance.

and the guide bolts by any'chance become -twisted o r loosened, the shutter will remain intact, still reventing the spread of ilames. 1

Itshould enoted that the closing means revealed in the present invention is .adapted tobe employed tocover openings from the exteriorof the buildings, each slat of the shutter of 'which is adapted to engage or communicate with the frame of the' opening 'at its base such a manner as topresent a shutter provlded with a series or plurality oi' platesor slatsarranged vertically-at an angle to a perpendicularand each provided with a traveling guide-rod or rodsv disposed at a similar angle, by which means cach of the movable'slats is ada ted to fall in an angular direction when re eased toward the frame of the opening to be coveredand to rest with the lower edge of eachlslat in communication with the fraxneof the opening, the Whole l shutter falling in' -a line disposed fat an. angle lto the frame ofthe opening to be closedythe' utter to said opening.

Various changes or modifications may be made in the details'vof construction of my improved self-.closing shutter or door, such, for instance, as changing the angle .offthe upper and lower flanges of the several sec-'11 tions, as `shown in Figs. 1 land 3, so as @to overcome any strain that might be inl the. bolts orrods, where the iiangesv'are. at right angles to the body ofthe section. y
