END CONSTRUCTION FOR RAILWAY-CARS.

Application filed May 10, 1916.

To all whom it may concern:

Be it known that I, VINTON E. SIssoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in End Constructions for Railway-Cars, of which the following is a specification.

My invention relates to sheet metal ends for railway cars, particularly box cars, designed to take the place of the ordinary wooden end sheathings either in new cars or in the repair of old cars, the end walls of which, particularly when of wood, are frequently broken out by shifting cargoes so as to require replacement.

One of the objects of the invention is to provide a sheet metal end for a railway box car in which the lower part of the end is so constructed that it is possible, without sacrificing strength, to omit the usual end sill, which, if of metal, adds materially to the weight of the car and the expense of its construction.

A further object of the invention is to provide certain novel arrangements for securely uniting the end sheets of the car to the end framing and joining together the elements of the end framing and under frame of the car whereby the end of the car as a whole will be very strong, rigid and durable so as to be capable of withstanding the inertia thrusts of the cargo, weaving stresses and such other shocks and stresses to which this part of a box car is subjected when in service.

The invention consists of the several novel and improved constructions, arrangements and devices to be hereinafter de scribed and claimed for carrying out the above stated objects and such other objects as will appear from the following description.

The invention is illustrated in certain preferred embodiments in the accompanying drawings, wherein Figure 1 is a fragmentary front elevation of a railway boX car, in which the end structure is constructed in accordance with my invention.

Fig. 2 is a sectional plan taken on line 2-2 of Fig. 1 with the flooring, side sheating and other parts omitted.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 5, inclusive, of the drawings, 10 designates the draft sills of a car which are here shown as being formed of ordinary commercial steel, 2- shaped in cross section, and 11 designates channel shaped side sills. The draft sills are secured to an angular member 13 which extends from side to side of the car and has its horizontal flange 14 riveted or otherwise secured to the upper flanges 15 and 16 of the draft and side sills, respectively. Angular members 17 are arranged below the angular attaching member 13 and are secured at their ends to the vertical webs of the said draft and side sills by means of angular gusset members 19, 20. The end sheet 21 is preferably formed with horizontal pressed corrugations 22 which terminate within the edges of the sheet so as to provide fiat surfaces 23 adjacent said edges. The vertical edges of the sheet are bent at right angles to the main portion of the sheet so as to form angular attaching flanges 24 which are secured to the corner posts 25 by means of bolts 26. The upper edge of the end sheet may be secured to the end plate or upper portion of the framing of the car in any suitable manner. This part of the structure has been omitted in the drawings of this embodiment of the invention. The lower edge of the sheet 21 extends below the flooring of the car and is cut away, as indicated at 27, so as to lit over the draft sills 10 and is secured to the vertical flanges 28 and 29 of the angular attaching member and braces 13, 17., respectively, by a double row of rivets 30, 31. The lower edges of the flanges 2d are riveted to the outer surfaces of said side sills. 32 is a short angle riveted to the end sheet and to the draft sills. The buffer casing 33 is secured to the draft sills and to angle 32.

With a car end constructed as above described, it is possible, without sacrificing strength, to entirely omit the ordinary end sill. The lower part of the lower end sheet is stiffened and rigidified so that an end sill is not. required. The saving in expense of construction is considerable. There is also a saving in weight which is an important consideration in a freight car. The draft sills are firmly attached to the lower end sheet. The end sheet serves as a plate girder with respect to the vertical stresses exerted on the body of the car by the draft rigging. The horizontal disposition of the corrugations adds considerably to the strength of the sheet as against such stresses. The reinforcing angles 13 and 1? stiffen and strengthen the bottom of the sheet as against the stresses exerted by the draft rigging, longitudinally of the car. The draft sills are connected to the end sheet and its reinforcing angles and the latter are firmly united with the frame members at the sides of the car so that a structure is )rovided that is extremely strong and rigid and at the same time very light in weight. The end sill. of a box car of ordinary construction has to be made very strong, and conse quently heavy, because it has to take care of the up and down stresses of the draft rigging as well as the thrusts and pressures in drafting and buffing. F or this reason it has been customary to employ cast steel or pressed steel end sills which, besides being relatively expensive, add considerably to the weight of the car. By employing a steel horizontally corrugated end sheet this ele ment will be sufliciently strong to take care of the up and down stresses. The transverse reinforcing members need be made only heavyenough to resist the thrusts and pressures fore and aft of the car.

34 designates the end lining which is secured to nailing strips 35 arranged in the recesses formed by the corrugations, and to the flooring 36.

In Figs. 6 to 12 inclusive, I have illustrated another embodiment of my invention, in which the side plates, end plates and cor ner posts are made of steel instead of being made of wood, as illustrated in the preced ing five figures. In this construction the upper framework can be made very rigid and presents certain novel features in the construction which Will be apparent from the following description: 10 designates the draft sills, 11 the side sills, 37 the corner posts, 38 the end plates and 39 the side plates of the car. The corner posts are preferably angular in cross section and are secured with rivets 4:0 at their lower ends to the vertical webs of the side sills 11. The upper ends are offset, as shown at ll, so as to extend inside the side plates 39, and are riveted to the vertical web of said plates and to the inner surface of the depending flange 42 of the end plate 38. The side plate 39 are preferably Z-shaped in cross section, and are further secured to the corner posts by means of the angular gussets 43 which are riveted to the corner post and to the lower horizontal flange 44 of the side plate. A diagonally'extending brace 45 is secured to the upper flange of the side plate and to the horizontal web of the end plate 38. l have shown the end as composed of two metal sheets 46 and l7, the upper one of which overlaps the lower sheet near the middle of the car so to provide a water tight joint. The sheets are preferably formed with horizontal pressed corrugations which terminate within the edges o'r' the sheet so as to provide flat marginal portions 49 which are secured to the inner surfaces of the angular corner posts 3 the use of the angular corner posts the wardly projecting corrugations can be u longer, that is, so that they extend cl" .1 to the edge of the sheet than is possible in a construction where an ordinary wood cori er post is used. The upper edge of the shot is secured to the inner surface of the flan e 42 of the end plate 38. Located interm ate the draft and side sills are 50 w 1 support the flooring 50 These sills are preferably Z-shaped in cross section and ar ranged so that their upper ed ge alines with the upper edge of the side sills, such tion being a short distance above the upper edge of the draft sills. An angular reinforcing and stiffening member 51 for the lower edge of the end sheet 46 extends from side to side of the car and is so arranged that its downwardly extending flange 52 overlaps the ends of the side, intermediate, and draft sills, the upper edge of the draft sills being cut away, as indicated at to permit such an arrangement. The horizontal flange of the angular member 51 is riveted to the upper flanges of the side and intermediate sills and to the upper flanges of the Z-shaped draft sills 10 through filler blocks 54 (Fig. 9). The lower edge of the end sheet 46 is riveted to the depending flange 52 of the angular attaching member 51. The connection between the sills of the car and the attaching member 51 is further strengthened and rigidified by angular gusset members 55, 56 and 57. The angular members 57 are particularly designed to pre vent any outward spreading of the .draft sills. Any tendency the draft sills may have to move inwardly is resisted by the position of the buffer casting 58 which is positioned between the draft sills and secured to the inner surfaces of the vertical webs of said sills by means of rivets 59. The buffer casting shown in this embodiment is provided with an integral flange 60 which is secured to the end sheet 46 and attaching member 51.

In Figs. 13 to 16, inclusive, I have shown another embodiment of my invention. The upper portion of the structure shown in these figures has been omitted from the drawings, as this structure may be substantially the same as that shown in Figs. 6 to 12, inclusive. In this construction, in order to insure a waterproof joint, I have shown an insert 61 of soft material, preferably tar paper, between the attaching surfaces of the sheet 16* and the corner posts "37 The angular attaching member 51 is riveted to the upper flange of'the draft sills, as shown at 62 (Fig. 14;), and to the lower flange of the intermediate sills 50 as indicated at 68 (Fig. 14). The ends of the attaching member are secured to the vertical webs of the side sills 11 by means of the angular gusset members 6 1. 65 designates rivets which secure the lower edge of the sheet 46? to the vertical flange 52 of the angular attaching member. 66 designates diagonal bracing members preferably T-shaped in cross section, which are secured to the member 51 and to the intermediate sills 50 The draft sills 1O are braced against outward spreading by means of bracing elements 67 which are angular in cross section and extend diagonally from the lower edge of said draft sills t0 the angular member 51 The buffer casting 68 is preferably formed with an inverted U-shaped attaching lug which extends between the draft sills and is secured to the horizontal flange of the angular member 51. The upper flanges of the vertical webs of the intermediate sills 50 are preferably cut away, as indicateclat 70, to permit the nailing strip 71 to be firmly seated on the horizontal flange of the attaching member 51 (Figs. 14c and 15).

While I have shown and described my invention in certain preferred constructions, it will be understood that modifications other than those suggested might be made without departure from my invention.

Therefore I do not wish to limit myself to the exact structure shown and described, except so far as specific limitations may ap pear in the appended claims.
