DIVISION A.

EMPTROVED IRON RAILWAY-GAR The Scheduie referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, RICHARD MONTGOMERY, of the city, county, and State of New York, have invented certain new and useful Improvements in Tron-Cars for .Railroads, and other purposes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a' part of this specification, in which- Figure 1 represents a side view of the frame of a freight-car, constructed according to my invention.

.' Figure 2, a section on line A B, fig. 1, and A C, fig. 3. I r

Figure 3, a section on line AD, fig. 2, or a longitudinal vertical section through the centre of the car.

Figures 4, 5, and 6, represent, on an enlarged scale, detached sections of parts of the car, to show more fully the means of uniting the framework thereof.

Figures 7 and 8 represent the coupling-pieces by which the top, bottom, and cross-pieces may, be united.

The nature of the invention consists in the production of very strong and durable, yet cheap, light, and complete] y fire-proof railroad-cars, and other vehicles, by combining beams oflongitudinally-corrugated metal, 'to constitute the framework thereof, and also in covering and enclosing the same with plates of plain or corrugated sheet-metal.

The manner of producing the longitudinally-corrngated metallic beams which I employ, and the quailties thereoflare fully set forth in United States Lettens Patent, No. 13,599, granted to me on the 25th day of September, 1855. a

' .In the accompanying drawings, 1 have illustrated the construction of an ordinaryfreight-car.

The parallel side-beams A A, of the proper length, are united at their ends, and at suitable intermediate points,"by cross-beams or girders O O, secured thereto by means of metallic coupling-blocks H, fig. 7.

Each of these blocks H is made with a single lower or bottom projection, 11", to be inserted into the central fold of the side-beam (see fig. 4) of the frame, and with two upper projections H H', formed at right angles to the first, sons to lit accurately within the double folds of the transverse beams U, (see fig. 5,) when laid thereon with their flanged faces downward, as illustrated in fig. 5.

' "The side-'pieces'A and girders G being thus coupled by means of the interposed blocks H -H, are firmly secured .by means of bolts or rivets h h passing through the ends of the beams A and O, and through the blocks, as shown in the drawings.

To the bottom frame thus constructed, of side transverse beams, upright beams B B are secured to form thcsidcs and top of the car. T hesc upright beams B, are made straight for a length equal to the height of the car, and then bend in a curve until. they reach a plane at right-angles to their length. v

' They are formed of longitudinally-corrugated metal of the same description as the straight beams A and 0, and are made to extend upward, vertically, from the bottom, or floor-frame, with their flanged faces 1) I; outward. Bending and arching over inwardly from either side at the proper height, they meet, and are united centrally, and thus constitute an arched 'support for the roof of the car, as illustrated in fig. 2 of v the drawings.

The lower end of each of these curved uprights is notched longitudinally, in each fold thereof, each notch being wide enough to pass over a fold of the girder when set down thereon at right-angles thereto, and deep enough to allow the ends of its flanges Z") to come into contact with the flange c of said girder, as, illustrated in fig. 5. I

When thus inserted in girder O, to interlock therewith, as described, the joint of the two may be secured by means of bolts passing through their combined ends.

I To make a yet stronger and firmer joint, however, I insert a knee-coupling, or block G, (tig. 8,) of solid metal, so grooved on its two faces to fit upon and embrace the projecting folds of both the girders O and uprights B, at the angle thereofland secure the whole by means of bolts passing through 13, G and G, as illustrated in figs. 2 and 5. g

Where it may bedcsirable to combine the uprights B with the side-beams A, iudependcntiy of the girders O, I do so by means of the coupling-pieces H, which I place upon and secureto the side-beams, as hereinbeforc described, (see fig. 4,) and then insert the ends of the uprights upon and between the two upper projections H H thereof, in like manner as upon the double-fold of a girder, G. (Sec ii.)

The upper curved ends of the uprights C may everlap and be riveted together, or be secured by means of lap, or tic-plates, inserted and riveted in the foids thereof, or the entire arch, including the uprights on either side, may be preferably formed out of one unbroken beam, as indicated in the drawings. (Sec fig. 2.

The sides and ends of the frame may be covered with smooth metallic plates, riveted in the 'usuaimannet to the flanges b b of the uprights B, said flanges presenting a smooth even surt'ace therefor.

The top may he covered in like manner with smooth metallic overlapping plates, but I prefer to cover the top with sheets of corrugated metal, placed with their grooves or folds running longitudinally, as illustrated in the drawings figs. 1, 2, and 3.

The combination thus made of the transverse corand upon the end of the rngations of the arched beams B, with longitudinal corrugations in the covering-plates F, gives very great strength in the structure without increase of weight.

The corrugated sheets F 15 may be most advantageously united at their ends in the manner el rly shown atf, fig. 1 ol the drawings and at the sides, as illnstratedat r ,lig. 2. These ends hould meetoveroue ol' the arched supportirig-beams B, (see j; lig. 1,} so as to be securely fastened thereto.

The number oiarched top-pieces B, as well as of girders O, and stringer or longitudinal beams A, are proportioned lo the amount of strain and weight to be borne by the car.

The bottom of the ear is closed by means otarchcd sheets oi corrugated metal 1),:(eurved in the dime-- tion of the corrugations) which are inserted between the girders 0, so as to rest upon the flanges c 0 thereof, as illustrated in ligl 3 of the drawings, and span the intermediate space.

, These arched sheets overlap at their edges so as to form an unbroken arch from end to end of the girders, and, front their form, brace and tie them,and impart great strength to the bottom of the car.

I The flooring may be completed by means of wooden planks E E, laid across the girders over the archedplatcs D in the usual manner, and be secured by nailing them into wooden strips 0 6, (fig. 3,} inserted for the purpose, and riveted into the. central upper groove of the girders U, as. illustrated in fig. 3.

i contemplate the combination of a wooden superstructure, with the platform constructed or" the beams and girders A and G, and, althouglnl have herein described more particularly the conslruetiou of on ordinary covered freight-car, i contemplate the application of my invention substantially as herein setliu'th to the construction of coal-cars, and other cars of irregular forms, as well as to various descriptions of vehicles for ordinary uses.

The coupling-blocks H G may be varied as to the inclination of their grooves o r projections, and of their faces, so as to fit into and support a joint formed at any-desired anglcother than a right angle and where it is necessary to make the body of the car with curved rather than angular bottom and sides, curved beams, similar to the curved uprights B, may be combined with suitable side-beams, substantially as herein doseribei'l.

The llSillg of couplingdiloelts [E G may be dispensed with or super-ceded by the intrmlnciiion of simple lapplates inserted between the folds at the ends of atljoiniug beams to break their joints.

-.'lhc advantages of aczn' thus constructed over those in common use, becanse'of their superior strength and durability, economy in weight, facility of construetiou, and security against fire, must be too obvious to need emnneration or argument.

' Having thus fully described my invention,

1 claim therein as new, aiubdesire to secure by Letters Patent .l The use of the corrugated-iron beams, constructed as described when applied to railway cars and other vehicles, in the manner and for the purposes herein set forth.

2. Theeombiuation of the curved top-pieces Bwiththe side or base-pieces A, and coupling-pieces H and G, operating substantially as described.

3. The corugated covering 1 arranged as described, in combination with the arched top-pieces B.

4. The coupling-pieces H G, or either of them, whenconstructed as described, and applied to the eorrugated beams of a railway-car, substantially as herein set forth.
