(01. "inssst) Thislnvention relatesto railway car constructions and more particularly toithe construction of acar endwall and transverse bulkhead supporting beam. r

One of the objects of the invention is topmvide a railway car end wall formed-by a corrugated sheet which is reinforced throughout its width.

Another object of the invention is: to provide a corrugated end Wall for a railway car which is reinforced by channel members which 'also form attaching means forfcoimecting an inner insulating wall to the end wall.

A-further object-of the invention is to pr vid means for securely anchoring a transverse'beam' which "supports a bulkhead in a refrigerator or like car.

The above and other objects and; advantages will be more "readily apparent from the following description when read in" connectionwith the fr accompanying drawing; in which- Figure :1 is a partial longitudinal section" thru a railway car embodying "the invention;

Figure 2 is a perspective View withparts broken away-end in section of one lot the reinforcing usualbottom l= 0- snpported on longitudinal beams or the like. The end wall of the car is formed by one or morev connected corrugated sheets ll arranged with the corrugations extending horizontallyand connected by a bracket l2 to the bottom It. The car is completed byvthe usual tops and sides not shown; which may be of standard construction.

According to the present invention the cormgat'ed end wall H is reinforced by elongated chamel shaped reinforcingstrips 13- mounted on the inner side of the end Wall with the flanges of the channels extending int'o and secured as by welding *or the like; to the bottoms of the corrugations. The webs of the. channels. are straight and lie in the plane of the tops hi the corrugations.

In the usual car construction, the connections are of maximum depth throughout the central portion of the car and taper to flat edges at the sides of the car. In order that the reinforcing stilt a rop rl zi i l qw e i i we. t corrugations throughout their length, the flanges of the strips ar e' tapered adjacent the ends as indicatedat H in Figure 2 to follow the taperin depth of i o iiee a ;n-v,. h os,- w m e tri reinforce the end sheets'substantlaliy from side to side. of the-car. v Z I g g 7 0n theinteriortofthe end wall an inner insulating wall is provided iormed by outer sheathing 15 and inner sheathing; l-d between'which insulating material l1- isusupperteds Thezirrner wall is connectedto the carend by-belts or'zlike elongated fastenings 11,8 extending through the inner wall H with their heads secured; in keyhole slots IS in the webs of the reinforcing strips. In assemblingtheinner wall to the car-end wall the bolts may'first'beplaced in zthe inner wall after which their heads; may be slipped 'through the Whole amenitie -l9 -and1.moved endwise to. lock the bolt heads in place; Thisconstruction provides a verysinrple a-nd highly "efllcient means of vfastening theinner insulating -;wall' to the car end.

At the upper edge of the car. end :a reinforcmg 1 strip ,2 l of somewhatsdifierentconstruction is-preferably employed. AS'- shown, :inrFigure 3,

the strip-:I-lincludes a-flange 22' tapered at its 7 of the top corrugation-:andthe edge or the web 23 "may be welded or otltierwise secured to the uppercfiat edge 10f the car and Prereraioly, a series of keylil'oleopenings 14' a are provided 'fnt the web 23' "to receive fastening bolts 25 extending 'thru the inner wall. An angle bracket 26 is welded-to theinner side of the *web 23 extending over the inner wall and having an upwardly extending flange 27' 'by which it may be secured to an: extension of the inner wall and to a romance-owns k v At the l'ow'erejn'd of the walla-reinforcing member "29 similar to the membe 21 is provided to carry bolts 31 "extending thin the inner car wall.

Near the lower end of "the corrugated end wan a "channel shaped bear-n '34 is provided, welded or otherwise secure-ate the car end afidtothe corner of the car. This beaniserv stcprovide additional "strength to "the car e'ndwaH to 'r'es'is of a shifting load in the 5051-1 transmitted thru "the bulkheadand thrn beams 36 to the car end. The outer ends of flanges of beam sweeter-n angular, and rest on the inner face of the car position.

end. A series of web plates 34' welded in place in the beam as shown in Figure 5, serve to give added rigidity to the beam.

Adjacent to the end beam 34 is a face plate 40 which is angular in shape and which serves as a backing for the floor pan and an added support for the floor grate support 36. Bolts 35 connect face plate 40 and floor grate supports 36 to the end beam 34. The beams 38 support a floor grate 31 as shown.

The car shown is a refrigerator car which carries a bulkhead 38 for dividing the car into an ice-compartment adjacent one end and a central lading compartment. The bulkhead is preferably movable in the car as more particularly described and claimed in my Patent No. 2,331,197. When in its extended position as shown, the bulkhead is supported in socket members 39 carried by the inner ends of the beamsz36. Similar socket members 4| are provided adjacent the end of the car to su port the bulkhead when it is in its retracted The beams'36 are supported'above the bottom plate 10 by a transverse beam 50 spaced from the end of car and underlying the bulkhead 38. A floor pan 43 extends from the transverse beam to theend of car and has flanged sides and ends turned up to provide a receptacle to catch water coming from the ice compartment above. A floor 44 extends under the lading compartment of car 'between the transverse beams. A wood beam 42 "is fitted-beneath -the projecting top of transverse beam to' form a dam between the space under the ice compartment and the space under the lading compartment.

In order to secure the beams 36 to the transverse beam '50 supportingmembe'rs 45 are providedconnecting to the inner ends of beams 36 under the bulkhead when in its extended position. 1 The supporting'members 45 are so formed as to permit air circulation longitudinally of the car therethru. The construction of the transverse beam 50 for securely fastening supporting members 45 to the bottom plate I0 is shown in Figure 4.

It'consists of a metal strip having a central body portion 46 with one end turned under to form a channel shaped section as indicated at 41.

Registering keyhole openings 48 are provided in "the central portion 48 and the turned under end 41 of the beam to secure fastening bolts 49 which 'connect'the supporting member 45 to the beam.

stiffening plates 41' are welded in between the central portion 46 and the free end of flange 4'1 'adiacent to the keyhole slots to prevent bending of flange when bolts 49 are tightened. The beam has an angular skirt portion 5| at one side which has secured thereto gusset members 52. The gusset members as shown, are channel shaped in section with angularly cut flanges, the upper portion of which may be Welded to the skirt 5| and to the webs of which are bolted the dam beam 42 by means of the bolts 54. Gusset 53 may be placed on dam beam 42 on side opposite from gusset 52.

Gussets

52 and 53 are securely fastened to the bottom plate IU of car. With this construction the beam and the parts supported thereby are fixedly anchored in the car and will not shift under strains to which the car may be subjected.
