' CAR-END CONSTRUCTION.

Application ld February 4,1925. SerialNo. 6,740.

Railroad freight cars designed and placed in service a decade `or more ago vare failing to meet present day conditions brought about by the longer trains, heavier locomotives and the elassitication hump yard. This is particularly true of the end constructions which are being knocked out or `broken by `the shifting of the lading as the end has been weakened by the torsional and weaving movements of the car in service, which service conditions it was not designed tomeet. This is especially true of box and other house cars. l

The end constructions Vfail in numerous ways, the. most frequent of which is bythe end or corner` post breaking or becoming detached from their moorings at top or bottom. The end sills decay and failtoperform their function of supporting the draft sills from drooping. The end sheathing decays so t-hat it not only fails to hold the grain within the car but also does not perform its function as a. gusset or bracing to resist the lateral weaving of the car body.

It is expensive to replace an end of a car on account of the cost of material and labor, as well as the time the car is out ofservice and, therefore, not producing revenue. Investigation shows that `the ends of `an old box car must be replaced or `repaired two or three times a year on an average. All steel car ends are in general use andare easily applied to new equipnient as the `design can be arranged to accommodate them,butit'is expensive in time and material to apply such` all steel car ends for repairs, because the old wooden ends walls of thecanmnst be removed beforethe steel end is applied. rFhe old end is scrapped and wasted.

It is preferable to provide means for reinforcing and strengthening the vulnerable parts of the old end wall of the old car without necessarily removing or replacing the old members thereof, eventhough such frame members are broken.

'it has been proposed toreinforce the end 'one edge) but to'secure it to a separate connecting member so that the corrugated plate can be applied to Vany width of car by adkjusting the relative position between the con- `nectmg member and the corrugated plate.

Thus a particular vcorrugated plate canbc used on any one of a series of cars.

The invention resides in providing means for adjustment of the relative position betweena reinforcing plate forthe end wall of a railway car and its attaching member.

Another object of the invention is to provide a reinforced plate which not only aids in resisting the thrusts of the shifting loads, but also reinforces the old frame members of the end wall to enable. th'emto better resist the lateral weaving movements of the superstructure of the car.

ln the drawings:

Fig. l is anendelevation of a railway box car showing the device applied thereon.

Fig. 2 is a section `along line 2 2 of Fig. l.

Fig. 3 is an enlarged section on line 3 3 of Fig. l.

Fig. 4 is a side `elevation of Fig.

Fig. 5 is a fragmentary detail'of the end of the plate shown in Figs. 3 and 4.

F ig. 6 is a fragmentary detail ofrthecon-i necting' member of Figs. 3 'and 4.

The old component parts of the car are shown wherein l is the end sill; 2 the end lplate; 3 the corner post l4 the end: post; 5 the end diagonal braces; lO the side diagonal braces; 1l the side plate; l2 the side sill and 13 the end lining.

The reinforced and reinforcing plate 14 is preferably positioned on the outside of the car end wall and is secured to the end sill l, the corner post 3, end post 4 and' diagonal braces 5, as shown in F ig. l, thus retarding the lateral weaving movements ofthe superstructure of the car. This plate 14 is preferably provided with horizontal corrugations l5 or other stiifening means, terminating within its opposite edges, which receive the shocks imposed upon the end wall and transmit them to the connecting members 1G which are. secured to the car. If these connecting members are oll angular formation, one leg (17) is secured to the car (by bolt E25) and the other leg (18) is secured to the plate 14 and to the car also it desired. As stated, it is desirable to have adjusting means between the plate and the ronnecting member, therefore, I provide horizontally slotted holes in either the plate or the connecting member and provide round holes in the other member. Slotted holes may be provided in both the plate and connecting mena ber but it preterable to have slotted holes in the plate and round holes in the connectin member.

it is only necessary to have the means of adjustment at one corner oit the car as one connecting member and one end ot the plate may be rigidly secured together before the device is assembled on the car.

In applying the device to the car, one connecting' member 1G is rigidly secured to the plate 1st and the connecting member attached to the car. The bolts 2O (or other securing devices) without their nuts are then placed in the slotted holes 19 at the other end of the plate with their heads towards the car and held in place by pressing the plate 1a against the car. lThe other connecting member 16 is then placed in position and the bolts 2O moved horizontally in the slotted holes 19 until they register with and project through the round holes 21 in the connecting member, then the nuts are applied to the bolts. rlhis arrangement constitutes means to provide adjustment oit the relation of the plate to the connecting mem` ber and at the same time to secure these two parts together.

The saine relation exists between bolts V2O, slotted holes 19 and round holes 21 as between bolts 22, slotted holes 23 and round holes 24. However, bolt 22 secures the plate and connecting member to the corner post, while the bolt 2O only secures these parts together. Either of these constructions may be used and come within the scope ot thisv ment of the relation of said provide adjustment ot the relation ot said plate to said angle.

2. In Vcombination with the end wall of a railway car, a metallic plate having horizontal corrugations formed therein, said plate provided with holes adjacent one edge thereof, a vertically positioned angle with one leg having holes therein and with the other leg secured to the car, one set of said holes being slotted and the other set ot said holes being round, and means detachably engaging said holes to provide adjustplate. to said angle.

3. In combination with the end Wall of a railway car, a metallic plate having horizontal corrugations formed therein terminating within, the plate, said plate provided with holes adjacent one edge thereof, a vertically positioned angle with one leg have ing holes therein and with the other leg secured to the car, one set of said holes being slotted and the other set of said holes being round, and means detachably engaging said holes to provide adjustment of the relation of said plate to said angle.

4. In combination with the end wall oit a railway car, a metallic plate having corrugations formed therein, said plate proA vided with slotted holes adjacent one edge thereof, a member provided with round holes secured to the car, and means detachably engaging said slotted holes and round holes to provide adjustment of the relative posi` tion between said plate and said member.

5. In combination with the end wall ot a railway ear, a metallic plate having horizontal `eorrugations formed therein, said plate provided with slotted holes adjacent one edge thereof, a member provided with round holes secured to the car, and means detachably engaging said slotted holes and round holes to provide adjustment of the relative position between said plate and said member.

6. In combination with the end Wall of a railway car, a metallic plate having hori- Zontal corrugations formed therein terminating Within the plate, said plate provided with slotted holes adjacent one edge thereof, a member provided with round holes secured to the car, and means detachably engaging said slotted holes and round holes to provide adjustment of the relative position between said plate and said member.
