DIvIsIoN B.

To all lwhom 'it may concern Be it known thatJ I, RICHARD Morire-OM- ERY, of the city, county', and State 'of` New York, haveinvented a new and uset'nlImprovement in Floors or Platforms for Iron Rail` way-Gars, and for other structures and i do hereby declare the following to be a full andexaet description thereof, reference being had to the accompanying drawings forming a part ot' this sneciiication: y

The nature of my invention consists ol a fire-prooi' support for a floor, composed ot' arched metallic plates, corrugated in they direction of the curve ot' the arch, inserted bctween and resting upon metallic beams or gird` ers, in such marinier' as to span and close the saidarches not only furnishing an intermediate central support required, but also constituting a neat and or? .nal'ucntal ceiling for the rooin below.

In the accompanying drawings, Fig. 1 is a persl'iective View, illustrating the upper, side ot' my improved floor when planked over, embracing also aside elevation, or section therein the beams or girdersesupporting the same. Fig. 2 is a Isimilar view, giving a perspective* of theunder side o'f the door` or platform, as' constituting aceilingforan apartment beneath it. Fig; 3 is a section, inline a' of .Fig. 2, taken transversely through the arched plates and parallel to the giro'ers.- v .',llie arched corrugated plates D'D may be formed of thin sheet metal, corrugated into folds ofI any suitable depth and width, and arched in a curve of any desired radius. These may be readily manufactured out ot' means' ofthe improved machine for the purpose, vfor the which I obtained Letters Patent in the United States, bearing-date April 12, 1.859, andnumbered` 23,599. My improved doors are constructed by first manner, at suitable distances apart upon lthe framework or walls intended for the support thereof, a series of parallel, `-.transverse met-allic beamsor girders C C.- I prefer to use for it i-s found preterabldto obtain a The plates .arched plates D, the ends ot' nevertheless, be also the purpose beams vformed. with projecting ilanges anon' either vside thereof, (such as l my patent longitudinali y corrugated beams, illustrated in the drawings, or the ordinary L and I iron rails and beams in common use,)

from the fact that the flanges 'ailord a ready support for the ends of the arched platesR Between these ilanged beams or girders C C I insert Ythe arched corrugated plates D, se

that, with their ends resting upon the'ianges a a. of the beams on' either side, they will completely span the intermediate open--spaee. p

v may oe arranged to f overlap each other, and thus form azontinu` The edges of the plates D ous corrugated arch the'entire length of the girders. In the construction of lioorsfor cars, boats, and other light structures, l yprefer to use corrugated plates, so curved as that the crown'of the arches formed thereby between the beams shall be on a level trated in the drawings, and'thus ai'ord intermediate vsupport for the boards E E,with which the doorin g may be finished ;t but Where.

or bearing ofl the ooring, y space between the beams and over the arches with cement or concrete,

plates of less curvature may D, thus formed and inserted ,be-

tween vthe beams or girders 0 C, not only serve p to fully close the intervening open spaces, and i to alford a firm, superimposed weight, buuform also ties or solid support to `carry any braces between the beams of; the rstrongest nature. Hence the doors or platforms of. cnrs,

orthe decksl of vessels constructed therewith, will endure almost as much strain or pressure laterally as longitudinally, but with greater elasticity. Although lconsider flanged beams,

as described, preferable for supporting the the plates may,

grooves in the beams, instead otanges. rBhe extreme lightness ot' a floor thusconstructed of metahas compared with a looringvof metallic beams and brick arches, ,renders it far preferable to the latter, while it may be. made as completely and strength.

I am aware that the employment of eomffas is customary in, llooringover .and upon arches of ,masonry bc employed.,

i with the upperl lsurface', of the beams or girders (J C, as lilluswider support a by tilling in the sustained by means of fire-prooi', and of equal si'ilidity;

gated metallic arches constructed of sheet metal, so connected, by metallic rods forming chords to the arcln'as to relievey the Walls from their` thrust, .for the purpose of spanning` wide 'intervals and kof vsupporting a. flooring', ofrt'orniinar oot',l1as been heretofore proposed,y (such an invention being described in my apilication for Letters Patent still pending. I do not, therefore, in this application, claim corrugated arches connected by rods forming chords thereto. Nor do I claim, broadly, the use and application of arched corrugated metallic plates; but f What I do claim as my invention,` and desire to secure by Letters Patent, is

A metallic support for a door, whether the latter formed of Wood or other material,- composed of arched metallic plates, corrugated in. thedirectiou ofthe curve of the arch and metallic girders, on or against which said plates abut, substantially as herein described.
