END WALL FOR RATLWAY CE RS,

Application filed March 8, 192 (5.

Reference is had to the accompanying drawings, which illustrate the preferred form ofthe invention, though it is to be understood that the invention is not limited mule exact details of cons ruction shown and described, as it is.oi' vious that various thereof within the scope of the claims will occur; to persons skilled in the ap i invention relates to the construction ot a railway car having an ehd wall made ofjone or more metallic plates secured to-- gether and reiniorced withstiiiening and bracing. members. While efforts are made o to block the lading in the car, the shocks caused by the heavy locomotives, the emergency airbrake, and the classification hump tear the lading away from its moorings and throw it against the end of the our, and the lateral weavingof the car throws it against the side oiv the car. The invention is readily adaptable to box, gondola and other types ot' railway cars. 4

7 One of the objects of the invention is to provide afwall element which has great strength to resistthe torsional and weaving stresses which exist in. a railway car, when moving in service. These stresses are causedfby the Iinertiaof the roof and superstructure" when the train is. suddenly stopped; rough or uneven track; the superelevation. of the track on curves; the. lateral inertia in rounding curves; eccentric thrust due. to the lading being secured to one side of the car; the cars being cornered; the use of push pole pockets, etc. Such stresses rack and distort the superstructure which decreases the life of, the car, and also causes the. car to leak grain, sand, and other'suchmaterial. Furthermore, such stresses cause leaky roofs and lealry and inoperative side and end doors.

The tendency of present designs of all metal end walls to bulge is resisted partially by the corrugations, stiffening members or whatever means have been provided to transmit such stresses to the side wall or frame members of the car. Such tendency is also resisted by the corner post of the car ctin as a vertical beam supported at its top and bottom and sustaining a horizontal load; in other words, the bulging of the end would pull the opposite corner posts toward each other. This bulging also tends e ia e. 31 5 to pull the end (or side) platedownwardlv and the end (orside) sill upwardly. I in rny construction the end wall is resiliently or. yielding ly attached to the frame members ofihe car 'and the stiffening means terini nete within this resilient arrangement and are not attached to) the car namefmm hers. "With' such a construction the strains and d stortions of a bulging: end wall are not. transmitted to the l ia ne iiiembers of the'czir. The stranger a bulging end Wall are concentratedin the end Ran" itself and not distributed to other: parts'ijof. the car. thus reducing the cost to 'repair the andI simplifving tlie r eplacemeht' of the end we r.

Another objectof the; invention is to attach an end wall to a. railway, car so. that its distortion, due to bulging; is not transmitted to the :nljaceI1t-. fra1nemembers 'bt the car.

Another objectis to form a depressed panel in a metallic end wall which. reinforces and strengthens the end; wallf andet 'the same tlmeiprovides a bearing' surface" 61 lining b oards. I i

In the: drawings:

Fig. 1 showsan end elevation of rail- Way box car with my invention: applied f l r vi' i- 2 is a sectionon line 2 2,of Fig.- 1.

F g. 3 is a section on line 3 3 ofFig; 1.

Fig. 4 shows amodification wherein the tran sv erse beams: arefpositioncd o-rizon tally. Y

The usual railway box car is provided with an end sill 1; end plate 2 and corner posts 3 whi ch constitute' a rectangular frame for the end wall; The, bot'tbnifof the end plate '2 sometimes conforms to theqslop es A of the root. In a gondola car'the' ,top. 'end' chord is a frame member. i z

My end wall comprises one or more metal- 110 plates 4i-5 connected together and secured to the above mentioned end frame. The end wall has a central portion 6 offset (preferably depressed inwardly toward the car) so as to form a continuous web 7 adacent the end frame. This continuous web, however, is not secured to the end frame so that if the end wall bulges its distortion is not transmitted to the end frame members.

The oilset central portion 6 of the end Wall is reinforced by a plurality of transverse beams lfl ll which cross the cencured to the continuous web.

tral portion and are preferably the same depth as the continuous web 7. These beams terminate adjacent the opposite portions of the web and are not secured to the adjacent frame member so that any distortion or deflection of any of these beams is not transmitted to the end frame of the car.

In the preferred form there are a plurality of plates connected on horizontal lines forming the end wall with a central reinforcing beam 10, as shown in Fig. 1.

It is desirable toline metallic end walls with wooden boards to prevent the moisture on the inside of the metallic plate. due to condensation, from coming in contact with the lading; furthermore, such Wooden lining boards act as cushions to absorb minor shocks caused by the shifting of the lading. In order to line my end wall I .provide wooden nailing strips 20 positioned between the con tinuous web and the adjacent frame memher, which nailing strip is preferably secured to the end wall either at the marginal portion, as shown in Fig. 3, or it may be se- The lining boards 21 are preferably positioned normal to the direction of the reinforcing beams and are nailed or otherwise secured to the nailing blocks and are also preferably secured to the central beam by bolts 22 or other means, therefore, when the end bulges the lining boards simply bend or deflect with it. The lining boards are in contact with the ofiset portion of the metallic plate so that they are backed up or supported over substantially the entire area of'the end wall.

In Fig. 4 the plates 30 31 are connected along" horizontal lines and the transverse beams 82 are also positioned horizontally.

I claim: I

1. In a'railway car having "four members constituting a substantially rectangular frame for an end wall; the combination of an end wall secured to said frame having an offset central portion forming a continuous webwith portions-parallel to and adjacent each of said members but not secured thereto, and a plurality oftransverse beams cross ing said offset portion terminating adjacent the o 'posite portions of the web.

2. l n a railway car having four members constituting a substantially rectangular frame for an end wall; the combination of an end wall secured to said frame having an offset central portion forming a continuous Web with portions parallel to and adjacent each of said members but not secured thereto, and a plurality-of transverse beams crossing said offset portion terminating adjacent the opposite portions of the web, which beams are substantially the same depth as the web.

3. In a railway car having four members constituting a substantially rectangular frame for an end wall; the combination of an end wall comprising a plurality of plates connected along horizontal lines secured to said frame having an offset central portion forming a continuous web with portions parallel to and adjacent, each of said membars but not secured thereto, and a central vertical beam crossing said offset portion terminating adjacent the opposite portions of the web.

4.
