FLEXIBLE FIRE-:RESISTING CURTAIN.-

To all whom it may concern:

Be it known that I, EDWARD HARRISON Mo .ILOUD, a citizen of the United Sta'tes, residing at 209 South Monroe avenue, Columbus, in the county of Franklin and State of Ohio, have invented new and useful Improvementsin Flexible Fire-Resistin Curtains; and I do herebydeclare the fol to be a full, clear, and exact description of the invention, such as will enable others'skilled in theart to which it appertains to make and use the same.

The "object of the owing present invention is to provide a flexible fire-resistingcurtain that S diation' of heat, and, further,

willtend to-prevent the transmission and rato provide a "curtain oipeculiar'construction in which materials having different.

I 'lOI'lQ properties can be nt1hzed, without en.-

dangering the safety of' the curtain, The manner in which this is attained illustrated in the accompanying drawmgs'.

ductive material, and if the two are rigidly connected together a stress will exist between them which would cause a rupture of the weaker material ordistort these ction 'from its original shape and probably cause the sections to become disengaged. To ob- T viate this, I have the: two materials made provision whereby can act. independently of each other. I'apply the non-conductive material to the metallic sections either in several short pieces or in "one continuous piece, as shown in Figs. 5 andfi. V In Fig. 5the' rivet a is laced iii-the center of the short length a. diihe rivets a) on either side of the'rivet a fit in circular'hol'es'in the metallic section Aand in elongated holes. a, in the material a. The excess expansion willoccur in. the

inetallic iece A, and the rivet a"will move towardt e oppositeyend of the-elongated hole It is obvious that the same results would be obtained by a reversal of the elongated and round holes with respect to the material in which they are perature the space a between the parts a, will be closed, but. will open slightly upon the application of heat. In F ig. 6 at the center 0 the curtain the material (I is secured rigidly by the rivet (1. fitted in circular holes in the material a and the metallic section A. The rivets a are spaced each side. As intense heat greatly impairs the' -efiiciencv of metal, rendering it less still and diminishing placed. At a normaltern-I its s trength,,I have endeavored to protect, as
