. METALLIC CAR.

SPEQIIFUATION forming part of Letters Patent N o. 723,067, dated March 1'7, 1.903. 'lpplication filed March 16, 1901. Serial No. 51,425. (No model.)

To ttZZ whom` t may concern,.-

Be it known that I, EDGAR W. SUMMERs, a citizen of the United States,`residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvementfin Metallic Cars, of which the following is a-full, clear, and exactdescription, reference being; had to the accompanying drawings."

The object of my-inve`ntion is to provide a sheet-steel'railwaycar which shall combine the characteristics of lightness, strength, and rigiditywit-h those of cheapnessl of construction and durability in service.

With this object in view I have turned my attention to all parts of the car; and the present`invention relates to the construction and support for the floor of the car, to the bracing of the carsides, to the construction and arrangementof the bolster-beam, and the constructionandarrangement of the draftbeam and its connection whereby the draft from one end of the car to the other is carried solely by the sides of the car without the necessity of intermediate longitudinal beams.

The invention may be summarized as consisting in the means which contribute to-the above ends, as hereinafter more fully eX- plained, and denitely set out in the claims.

Ihe drawings clearly illustrate my invention.

Figure l is a top plan of a portion of jt'he car constructed in accordance therewith. Fig. 2 is a bottom plan. Fig. 3 is a vertical longitudinalsection. Fig. 4 isa vertical transverse section. Fig. 5 uis a fragmentary horizontal section, being onthe line 5 5 of Figs.A 3 and 4. Fig. 6 is l a fragmentary vertical section, being on" the line `6 6 of Fig. 4; and Fig. 7 is a fragmentary vertical section on the line 7 7 of Fig. 3. Fig. 8 is an end'view of the casting for reinforcingthe draft-beam. y In the drawings, A A represent the sides of the cargB, the floor; C, the end; I), the bolster; E, the draft-beam; F, the draw-head, and .Gr` and H interior and exterior braces for the sides.

Thefloor "consistsof sheet-metal plates b,

.having their transverse edges turned downward and` riveted together, so as to make acontin nous smooth surface on the upper side.

.One or both of these downturned edges is double channel-beam by the abutting edges to contiguous plates, as over the wheel at b4 in Fig. 3. In either event Iy have provided by this means a very efficient and cheap construction, for metal is saved over a construction where a complete channel-beam is employed separate from the floor-plate. The construction, moreover, is stiffer, metal is saved in rivets, and smoothness of the upper side of the floor is obtained.

The sides of the car consist of continuous vertical steel plates riveted together at their ends. The lower edges of these plates are bent inward, as at d, Fig. 4, and are bent downward, as at ct. The portion d comes directly beneath the cross-beams, and these portions are riveted to the bottom flanges b2 of those beams. serves the alinement of the horizontal plate d. The floor-beams are fianged out at their ends, as indicated by b5, and these flanges are secured by rivets to the side of the car. The ends of the floor-plates are anged upward, as at 196, and riveted to the car sides.

The car sides are braced on their inner sides bygusset-braces Gr of peculiar construction. These gussets consist of plates doubled upon themselves and having flanges g, which are riveted to the sides of the car. At their lower ends the double web portions g2 continue down between the Hoor-plates and are there secured by the same rivets which hold the two 4licor-plates together. That floor-4 plate which is simply/flanged is offset, as shown, to allow for this projecting end g2. These gusset-braces are provided along the sides of the car as often as necessary. Iconsider that a brace at each side at about every third door-beam is a satisfactory disposition. The flanges g of these gusset-plates are The projecting flange d' preslightly odset inward to accommodate the upper inturned end h6 of the floor-plates.

On their outer sides the car sides are braced by suitable vertical members, (indicated by H.) These may be of the box-like form shown in Figs. Lt and 5 and secured to the sides of the car by outturned anges h, which are riveted thereto. There are preferably as many of these outer braces foreach side of the car as there are floor-beams.

Those outer braces which are opposite thev gusset-braces on the inside are secured by the same rivets. rlhe upper edge of the car sides are fianged outward and downward, as at a?, and these outturned flanges lie adjacent to the outer sides of the braces H and are riveted to the extreme upper ends thereof, as shown at h2. This. makes a very simple and cheap construction. The sides are all braced and the bracing is connected rigidly with the vdoor-beams. I so dispose the rivet-holes in the gusset-braces and outer braces that the same rivets will do for these braces and for the flanged ends of the Hoor where they overlap. The rivet-holes being disposed in the same manner on each gusset.- brace and exterior brace, each brace may have its holes punched at one time by the same gang-punch.

The boisterbeam (indicated by D) consists of an inverted- U -shaped plate, as shown most clearly in Fig. 3, the upper surface d. of which constitutesa portion of the floor, to the sides d of which are riveted the downturned flanges b3 of the door-plates, and the lower edges d3 of which are turned outward and riveted to a bottom plate d, and at the cenler of the beam to the usual center bearingplate d5. At their ends d2 the side plates CZ are anged inwardand riveted to the sides of the car above the bolster. An inner brace G is provided similar to the gussets G, eX- cept that the web portion gsdoes not extend through the floor. At its lower end thisl brace has its web flanged outward, as at g4, and riveted to the upper side of the bolster. The flanged edges ot' this brace overlap the edges of the braces H on the outer side of the car, and the same rivets serve to secure the flanges of the inner brace G' and the inner edges of the outer braces H, as shown. This makes a very rigid connection between the bolster and the fioor and sides of the car.

The draft-beam (indicated by E) is also an inverted-U -shaped beam. It has a top plate e, which abuts the under side of the end plat-e b of the floor, to which it is secured by numerous rivets e, these rivets being countersunk on their upper side to leave a smooth upper surface to the floor. The vertical sides e2 ot' this beain are flanged outward at their inner ends `and riveted to the bolster, as shown at es. At the lower edges the beam is flanged outward, as at e4, which lower edges are secured to the flanges d3 of the bolster and to the plate d* and where the draftbeam crosses the end C of the car to the 'lower end thereof by means of the plates c, which are riveted to the inturned anges c at the base of the car end and are also riveted to the flanges e4 of the draft-beam. This draft-beam lies between a pair of angle-bars c2, which are riveted to the car end, and lthe vertical sides e2 of the beam are riveted to the adjacent sides of these angle-bars.

Within the draft-beam is the reinforcing member J, which is preferably a steel casting of the form shown in Figs. 3 and 7. This casting is secured within the draft-beam by the same rivets which secure the beam to the angle-bars c2 andto the outturned flange c3 of the car end and by some of the rivets which secure the draft-beam to the cai-Hoor 117. The casting has strengthening-webs j depending from its upper suface and has inturned flanges j' for confining the draw-head F. This draw-head is of any suitable construction. It rests on the plate jz, carried between the websj3 of the steel casting and abutting the under side of the iangesy, to which the plate may be secured by bolts. The draw-head is guided by the inturned flangesj and by the downwardly-extending ange j* at the forward end thereof. By this construction the draft is carried directly from the draw-head through the steel casting to the draft-beam and from there by the fioorplates 137, which form horizontal girders, to the sides ofthe car, by which it is transmitted to the other end. This is an important feature, as it obviates the necessity oflongi- .tudinal beams under the car, lightening the car, and leaving the base unobstructed,should it be desired to provide it with-dumping features.

It will be observed that in the above-described car I have reduced the weight without sacrificing strength and rigidity by obviating longitudinal beams, by making the door-beams continuous with the floor-plates, and, furthermore, by so placing the parts that the saine rivets serve for several pur-` poses. This reduction of weightis a very important factor, since the expense of hauling a load is dependent upon the weight thereof, and the lighter the car the greater tne proportion which the paying weight-that is, the freight carried-bears to the `whole weight, which means that for the same capacity the efficiencyof the car increases with its lightness.
