END STRUCTURE FOR RAILWAY CARS.

Applicatonvled November 26, 1923. v'Serial No. 676,974.

Metallic ends for railway cars have been devised and are now in extensive use which are made of a plurality of metallic plates having parallel corrugations formed therein extending alternately inwardly and outwardly from the neutral axis of the corrugated panel. The corrugated plate is of ample strength to resist the shocks of the shifting lading and to resist the torsional' strains set up by the weaving of the car.

It is necessary, however, to line these metallic ends with a wooden lining so that the car may be used to transport any kind of lading. The lining prevents the moisture, due to condensation on the inside of the metal plate, coming in contact with the grain lading and causing mildew, or the car is loaded with cement, this moisture would cause hardening of portions of the cement requiring resacking. There are also limitations regarding the loading of explosives prescribed by the Bureau of Explosives of the Interstate Commerce Commission. It is frequently foundnecessary to drive nails into the side or end of the car when blocking the lading.

Corrugated endshave been lined by positioning nailing strips within the corrugated portion and nailing the lining to such nailing strips. These nailing strips, of course, are subject to shrinkage which may cause a loose lining.

One of the objects of my invention is to eliminate such nailing strips and secure the lining boards directly to the corrugated end in such a manner that each lining board bears directly against the inwardly projecting apices of the corrugations. .Any thrust or load imposed upon the lining vboard is, therefore, transmitted directly to the corrugatedend and acts as a beam for only the short span of the distance between the apices and the inwardly projecting corrug,a-tions. The construction, therefore, materially strengthens the lining boards, thus reducing the possibility of their breaking or splitting.

Another object of the invention is to provide means to hold the boards directly in Contact with the apices of the inwardly projecting corrugations. n

Another object of the invention is to strengthen the corrugated end by usingthe lining to distribute the load over several of the corrugations which is accomplished by positioning the boards rvertically if the corrugations are positioned horizontally or vice versa, or so that the direction of the corrugation is substantially ninety degrees from the direction of the lining boards.

Another object of the invention is to have the bolts so positioned that the nuts thereon are protected.

My invention may be used on box, gondola, stock or othertypes of railway equipment.

In the drawings: f

Fig. 1 is a front elevation of a railway car with myinvention applied thereon.

Fig. 2 is a cross section on line 2-2 of Fig. 1.

3 is a fragmentary enlarged view of my invention. y

Numeral 1 represents ythe center sill; 2 the flooring; S'the end sill angle; Lfthe striking casting; 5 the side and end sill construction; 6 the corner post; all of the usual freight car; 9, 10 and 11 arel metallic plates with corrugations 12 formed therein in the usual manner. The metallic plate has a corrugation formed therein having an outwardlyv projecting curved surface. The lining boards 17 extend in a direction substantially ninety degrees from the direction of the corrugations, so that they bear directly against the metallic plate on both sides of they corrugation. n

The bolts 18 pass through the liningl and theoutwardly projecting apices of the corrugation and by means of nuts 19 and washers 20 holdthe boards 17 iii-contact therewith. The washer 2O is formed to vtit the convex surfaces of the corrugated plate so that itv can adjust itself to the irregularities and inaccuracies of construction and yet maintain an even bearing on the corrugated plate and also provide an even bearing forv the nut 19. The concave washer also provides a yweatherproof construction preventying moisture from entering theA car by following the bolt. The washer 20 has projections 25 which form a recess 23 upon which the nut 19 rests. These projections forman added protection against moisture following the bolt and serve alsokv to prevent the nut from turning.

jAv metallic strip 22 extends onv the inside ofthe lining boards so. that it is not necessary to bolt every board to every corrugation unless desired. This is illustrated inA Figs. 2

and 3. This metallic continuous washer Y naarT be let in the lining boards s0 that the inner surface of the end will be flush.

I claim:

1. In a metallic panel having a corrugation formed therein with an outwardly projecting curved surface, a washer with an interior concave 'surface engaging said outwardly curved surface, said washer having a recessed exterior surface, and a bolt having` a nut bearing,` upon said recessed surface.

2. In a metallic plate wall element having inent on both sides ofthe corrugation, a.

washer with an interior concave surface engaging said outwardly curved surface provided with a recessed exterior surface, and

a bolt passing through the lining, corrugation and washer having a nut hearing upon Y said recessed surface.
