' PRESSED-STEEL GAR END.

vToaZZ whom it may concern:

be securely attached to the car. for example,

to the framing of a wooden box car of stande, either new or old. and is so constructe that it will effectively withstand the cargo thrusts, pressures and impacts to which the end of a railway freight car is suheected, and so that, furthermore, it will wirengthen the-whole car structure, against the racking strains incident to the use of a. car under ordinary service conditions.

A specific Object of the invention is to provide a sheet steel. car end comprising a plurality of; end sheets which are formed, for strength and rigidity, with pressed out ribs or corrugations and with overlapping margins conformed and arranged so as to provide, in effect, a reinforcing band or girth having greater strength and rigidity than the rest of the end, the invention contemplating preferably a disposition of the pressed out ribs of the sheets at right angles to this band orgirth so that the structure is capable of withstanding stresses and pros sures from all directions without undesirable deflection.

The invention has'for further objects such other 'new and improved constructions, ar-

rangements and devices relating to sheet 01: line 2-2 of Fig. 1;

Fig. 3 is a fragmentary vertical section Specification of Letters Patent.

Qand .Fig. 4L is a sectionalplan taken. online HofFigzS. f y Like characters of reference desigiiatedilte drawings a y ,p Referring to the drairihg, designates an end 'sill of a wooden boX 'carcf Ordinary construction 26 the corresponding, end plate, 27 the corner post and 28 the flooringhof aear. I The end structure consists, in this illustrative form of the invention, of two end sheets 29 and 3() which are provided on their vertical edges with flanges 31 overlapping the corner posts and securedthereto suit able means: The sheets are formed with vertically disposed or. substantiallyvertically disposed ribs or corrugations 32 I terminate within the edges of .th efrespe'ctive plates and are preferably spaced apart distances equal to their width givingthe sheet, in each case. uniformity of reinforcement parts throughout the several figure s of tlie by dividing it into aiseries of ribs of sub.

stantially equal strength, Theiipper sheet has a flat flange 33 which maybe secured to the end plate 26 by bolts 3i. the lower sheet a similar danger-35 which-"preferably extends downbrer and covers. the

outer face of the endsill 25. being secured thereto by lag screws 36 or other suitable attaching devices. Riveted tothefin'side of the lower sheet 30 is an angular iinen iber 37, the horizontal flange of which is secured to the end sill by bolts 38 andfpreferably '3 intervenes between the end silland theflooring of the car. The function ofithisf angular member is four-fold. It provides effective means for securing the lower end sheet to the framing of the car. By intervening between the sill' and the flooring it ma kes the car grain-proof at this place. It reinforces and strengthens the lower portion of the end structure against the inertia thrusts of the car- '0 at the place where reinforcement is particularly required. Heavy articles such as rails and pipe are usually placed down low in the car and it is such articles as these that are most likely to injure and break out the end of the, car by their shifting movements when the train is started or stopped.

gle member for se- ..-.ieet to the framing its the end sheet to be carried sheath lower sheet by a line of rivets 42 arranged between the inwardly pressed ribs 32 of the latter sheet and to both the upper and lower sheets by a line of rivets i3 passing through me marginal portions 39, '40 of said sheets. The girth member is preferal-ly provided with angular flanges 44 which may be secured by any suitable means to the corner posts 27, for example, by the bolts 25. By this arrangement a central zone. or band is provided extending across the car from side to side, which derives its strength and rigidity from the overlapping of the sheets, from the channel Formed girth member and, furthermore. twin the tact that the ends of the ribs on the lower sheet extend up into this pmtion of the structure. Gusset plates 16 may be employed ior aiding in anchoring the end sheets to the ear framing.

Because of the arrangements des'aribed the car end is not only eapable of withstand ing the heaviest; sort of cargo thrusts with out appreciable deflection. but also serves to carry some of the root load at moreover, provides an etlicient means for ie sting the \"veavingand other similar stre to which the railway box car is subjected when in service. The end, therefore, serves to strengthen and rigidi .y the entire structure of the our instead of being the weakest part of the car structure, a is usually the case in ordinary box car constructions.

I claim:

1. The combination with the t .r framing of a railway car, of a she-e in al end for the car eon'iprislng an end sa e; formed with pressed vertical. stilt'enine' 'l reing ribs, an angular member our 6, to the low iportionof said end sheet and anchored to the 30. lhchannel shaped girth member 41 is secured to the under frame of the ear, and e channeled, transversely extending reinforcing member provided with marginal flanges secured to the upper edge of the sheet. V

2. The combination with the end framing of a railway car, of a sheet metaend for the car comprising an end sheet to 4 ed with pressed vertical stifiening and reinforcing ribs, an angular member secured to the lower portion of said end sheet and anchored to the under frame of the car, and a channeled, transversely extending reinforcing member provided with marginal flanges secured to the upper edge of the sheet, and with. end flanges which overlap and are secured to the side members of the end framing of the car.

3. The combination with the body of a railway car, of a metal end structure for the car comprising an end sheet, an angular, transversely extending member at the bottom of the car body to which the lower edge of the end sheet is secured. and means providing a channeled, transversely extending. member at the upper edge of the sheet, said sheet being formed with etn'rugations which extend from substantially the lower to the upper edge of the sheet so as to distribute stresses on the end sheet to the aforesaid transversely "extending members.

4. The. combination with the body of railway ear, of a metal end structure for the car comprising an end sheet formed with substantially vertical cor igations which terminate within the edges of the sheet andare spaced distances apart, substantially, equal to their width whereb v the corrugated portion of he sheet consists in efi ect of a series of lll which function as beams of substantially equal strength, and means constituting trans verse. stidening members at the upper and lower edges of the sheet which transmit the stresses from the corrugations to the body of the car.
