This invention as indi'catedrelates to car construction; More particularly" it comprises structural elements: adapted to form parts of railroad cars especially those of the gondola and hopper type. It includes cross braces or cross ties for such structures and parts associated therewith such as bulk heads and gussets'and securing and adjusting elements. The invention is particularly adapted for metal car constructions but may be found desirable in connection with our bodies of other material such as composition sheets or wood combined with metal or other combinations thereof. v
Heret'ofore it has been the usual practice to brace gondola and other types of railway cars by means of cross plates or angle or channel bars which are riveted or otherwise secured to the sides. Such bracing members are necessarily of large size when made of sufiicient strength and "thus interfere with proper loading and unloadingoperations as well as lessen to some extent the effective load capacity of the cars. They are also subject to injury under conditions of severe usage and are especially subject to corrosion.
The principal object of the present invention is to obviate the difficulties referred to and to provide a car construction of improved form and which will have a longer term of service than those ordinarily em ployed. Another object, of the invention is to provide a cross brace and associated parts forrailway cars of the high side open type which may be economically manufactured and easily installed, and which also may b'erea'dily replaced when necessary. A
further object ofthe invention is to provide across tie which may be made in standard sizes and readily adapted for us'e to brace the sides of railway cars which vary in spa-cing from each other slightly from such standard lengths; without loss of structural strength and without deforming the sides of such car bodies and placing an undue strain thereon. Another object of the invention is lZOhfOl'Dl a cross tie of 'a folded sheet of meal of uniform gauge which will have a high degree of strength due to its cross sectional form and which will prevent the accumulation of d'irtand moisturethereon with attendant lessening ofithe life of the structure. Another object of the invention is to provide a cross tiewhichwillnot ie be removed with a'minimum of labor. other ob ect of the Invention is to provide a quire riveting across its lower edge because of its having sufiicient strength clue to the gauge ofthematerial andits cross sectional form as well as its method of attachment to the car sides at its respectiveen'ds. A still further object of the invention is to provide a cross tie adaptedto engage separable supporting members rigidly connected with the the car sides and from which it mayreadily cross tie and end supports which will embody adjustments for firmly holding-"the same against the end plate as well as malting the same readily replaceable. Other and further objects of the invention will appear in the course of the following description. To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.
The annexed drawing and the following descrlption set forth 1n detail certain structure embodying the invention, such disclosed means constituting, however but several of various structural forms in which the principle of the invention may be used.

As is clearly shown in Fig. 1 of the drawing, the high car sides 2 of a hopper car 1 .are braced transversely by means of a plurality of cross ties. The cross ties 3 are inserted centrally of their respective hopper compartments spaced a short distance below the top edge of the car sides and the cross tie 1 at its ends is engaged over and secured to the upper edge of a gusset plate or partition 5, and is secured at its ends closely adjacent the upper edges of the respective car sides.
The form of construction illustrated in Fig. 1 is shown in detail in Figs. 2 to 6. In said figures the cross tie is shown to be formed of a plate of heavy gauge sheet metal bent along its longitudinal median .wall 2 of the car.
line to form an upper edge 6 substantially .ably touch adjacent their lower inner edges.
No rivets or other fastening means are applied to the lower edges of the plate, the gauge of the sheet being sufiicient to maintain said edges in the position stated when the ends of the cross tie are secured to the respective car sides.
The means of connecting the cross tie to the car sides comprises as shown, a pair of flanges 9, 10, formed integrally by slitting or punching the ends of the plate at a central point before forming the cross tie. The end flanges are bent outwardly and are provided with holes for rivets 11, or other fastening means which serve to' connect the flanges to the adjacent car side.
hen it is desired to connect a cross tie of the form shown in Figs. 2 and 3 with a gusset plate such as is shown in Figs. 1 and 4, it is found desirable to flatten the lower edges of the depending side members of the cross tie adjacent the ends and place the rivets therethrough which will also pass through the upper edge of the gusset plate. In the construction illustrated a gusset plate 12 is clamped between the pair of parallel lower edges 13 of the cross tie adjacent each of its outer ends. The central portion of the cross tie will be of the same cross section as that heretofore described which is illustrated in Fig. 6. The gusset plates may be reversed to have their broader portions at their upper edges, the extent of the connection with cross tie being corrcspoinlingly increased.
Instead of forming integral flanges upon .the cross tie, it may be found desirable to provide'a supporting plate with a projecting boss or flange with which a cross tie with plain ends may be engaged. In the form of construction shown in Figs. 7 and S, a cross tie 15 of the cross sectional form shown in Figs. 2 and 3 is engaged over a suitably shaped flange 16 formed integrally with a supporting plate 17 which is secured by rivets 18 or other fastening means to the side The respective ends of the cross tie 15 may be secured to the flanges 16 by means of rivets 19 or similar fastening devices. The construction illustrated in Figs. 7 and 8 is also adapted for supporting a gusset plate as is clearly shown in Figs. 9 andlO, the gusset plate 21 being engaged between the parallel lower edges 22, 23 at the outer ends of the cross tie 24:.
In Figs. 12 and 13 in place of a flange upon the supporting plate over which the cross tie is adapted to engage. a suitably shaped flange 25 is provided which is adapted to engage externally around the cross tie 26 such flange being mounted upon a suporting pine 27 SCilIfCl by rivets 2s Grahaing a gusset 31" in a cross tie 32 engaged Within an external supporting flange 33 is shown. ThB'lQWGI edges of the cross t e are pressed to parallel relatlon and the upper edge of the gusset is'ins'erted between them and engaged by aplurality of rivets 34. i The end rivet 35 preferably will also extend through, the depending edges of the sup porting flange 33 as is clearly shown in Fig. 15.
'A still further Inodifiedform of cross tie support is shown in Figs. 16-19, the cross tie 41 being of the above described cross section acrossits central part as shown in Fig. 19, but being flattened to provide a pair of parallel sides 42, 43 adjacent each of its ends. A supporting plate 44 is provided with an outwardly extending inverted U- shaped boss 15over which the folded flattened end portion of the cross tie is adapted to engage. Rivets 46 or other fastening means may be engaged through suitable aperturesithrough the flattened sides of the cross tie and the supporting boss. The plate may be secured to the car side by means of rivets or other fastening devices 47.
'The cross ties heretofore described are adapted to be permanently secured to the car sides by means of rivetspassing through the integral flanges. of said cross ties or through flanges formed on supporting members which are riveted to the ends of the cross tiesJ In. the'construction illustrated in Figs. 2231, the cross tie is adapted to be detachably supported at each of its ends. In addition to the provision for the ready removal of the cross tie, the form of construction shown in Figs. 26 to 31 illustrates means for securing the cross tie in rigid adjustment with the respective car sides, and eliminating endwise motion thereon.
The cross tie, when intended forremovable connection with the car sides 51 is provided with a cross sectional shape similar to that originally described and illustrated in Fig. 3 with an upper edge of substantially semi-circular cross section and. depending flattened portions 52, 53 which approach each other at an angle and preferably meet at their inner lower edges, but which are unsecured by rivets or other fastening elements atany point along the lower edge. Integral side flanges 54, 55 are formed adjacent each of the ends of said inclined flattened portions of the cross tie as is clearly shown in Fig. 25. A supporting plate 56 is adapted tobe secured to the-adjacent side wall of the car body by means of rivets 57 or other suitable attaching devices. The
lower portion of the plate 56 is provided with anintegral enlargement 58 ateither side which is channeledat its inner edge to provide a pair of inclined grooves 59, 60, which areinclined toward each other to form a V-shapedgroove within which therespective flanges 5 1, 55 at the end-0f the cross tie '51 are adapted to be engaged. A plate o'r'strap 61 having flattened ends and asemicircular central portion is adapted'to engage over the curved upperfedge of the cross tie to hold the same-with its lateral flanges firmly engaged in the \l -shapedgroove of the supporting plate.
A pair of projecting ears 62, 63 are formed on the enlarged lower portionsof'the supportingpla-te. The flattened ends 64,65 of thes'trap 61 are provided with perforations in alignment with similar perforations through said ears, and bolts 66 orother suitable securing devices are engaged, therethrough -to draw said straps downwardly against the upper edge of the cross tie. WVashers 67 may be positioned between flattened portions of the strap and the adj a cent ears so that the degreeof clamping to as desired. v
The const'ructionjust described does not provide forendwise adjustment of the cross tie. It is found, however, that many cars be exerted upon the cross tie may be varied vary slightly in transverse dimension and in order to attach a cross tie to the same, it is necessary to move said car sides apart or 'draw' them together as the case maybe. This practice is undesirable where the degree of adjustment is considerable for the reason that a permanent stra in will be placed upon the car sides and throwall associated parts out of alignment. It has, therefore, been found desirable to provide for an endwise adjustment for the cross tie. This is accomplished by means of the construction illustrated in Figs. 26 to 31 inclusive. In said construction, the cross tie 71 at its ends is beveled downwardly at "its lateral edges and upwardly at each of its end'faces so thatthe flanges 72, 73 set at an angle as viewed from the side as well as when viewedfrom the end. The enlarged portions 74 of the supporting plate 7 5 are likewise provided with inclined forward faces, for each of the grooves 76, against which the adjacent faces of the inclined flanges maybe engaged. The remaining portion of each groove is adapted to receive awedge plate 77 which has bent portions at each lateral edge which are tapered downwardly, said plate is also of lesser transverse dimension adjacent its lower edge than at its upper edge. The wedge plates thus are adapted to prevent endwise motion of the cross tie and will firmly hold the same 78 similar to the strap 61 heretofore de scribed will serve tohold the @rossaefirmr within the V-shaped groove at the lower portion of the supporting plate, being secured thereto by bolts 7 9. Shims or washers may be inserted over said bolts between thestrap and the plate and may be of sufficient size to press upon the upper edge of the wedge plate to, force the same downwardly. In order to remove a cross tie of the character just described,it is merely required that the bolts 7 9 securing the'cross strap to the lower portion of the supporting plate be removed, the wedge plate forced upwardly and the cross tie removed upwardly from each of the V-shapedrecesses at its-opposite'ends. r
As has been indicated, the use of a sheet of metal of suitable gauge notonly provides a structure of great 'strengthbut one which may be manufactured at a minimum cost. If tubing of like weight were used with sockets or other securing means at each of its ends, the cost of the same would be greatly increased, and the strength of the structure less. By usingstandard plates as the stock from which the cross ties are made and cutting them to suitable lengths and bending them in the manner heretofore described, the manufacture of the cross tie is one which may be readily carried out by quantity production methods and without the employment ofhighly skilled labor. The end supporting plates last described may be formed of simple castings which likewise may be most economically produced. Thus a construction is provided which is superior to those in common use in the matter of strength and safety, and which at the same time may be manufactured and installed, or replaced, with one of the type last described, at a cost much less than that of constructions heretofore used.
