Definitions

  • end walls for railway cars are required to resist the terrific forces of shifting lading, such as piping, steel plates and planed lumber caused by the service movements of the car, par-- ticularly switching, coupling and air brake applications.
  • end walls have been made of one-quarter inch steel plates reinforced by a plurality vof integral contiguous parallel corrugations which are generally horizontally disposed so that the several corrugations function as a series of cooperating beams to transfer such force to the corner posts (or other frame members) of the car.
  • my reinforced metallic plate as providing an end wall for a railway car, but it may also be used as a side door for a railway house car; a drop door for a railway general service gondola car; a hopper door for a railway hopper car or a roof ifor a railway house car.
  • the safety appliance rules of the Interstate Commerce Act -require a clearance of at least v12" from the outer surfaces of the end ladder rungs to a vertical plane passing through the pulling face of the coupler knuckle when the striking head of the coupler is against the buffer on the car.
  • This-is called the end ladder clearance and cars not so arranged are subject to a One Hundred Dollarl ($100.00) fine and may only be moved by a railroad to the nearest repair ship.
  • the ⁇ objects of the invention is to form a.l tively thinkmetallic plate with a plurality of parallel corrugations with the metal so disposed as provide a series of beams of great strength .compared to the weight o'f the metalused and to apply such relatively thin metallic plate so corrugated to a railway car to constitute an end wall therefor wherein an end iadder'may be attached thereto/so as to provide thelegally required end ladder clearance, and at the same time, provide Yarailway car of greater inside .length and lesser train lengthA than has heretofore been designed.
  • l l f This invention is an improvement over the corrugated end walls disclosed in Smalls Patents No. 1,681,811 and No. 1,681,816, kboth of August 21,
  • Figs. 1-4, inclusive, show a typical form of my invention applied to a railway car wherein- Fig. 2 is a section on line 2-2 of Fig. 1.
  • Fig. 3 is a section on line 3-3 of Fig. 1.
  • Fig. 4 is a section on line I-I of Fig. 1.
  • Figs. 5-8, inclusive show a single plate formed similarly to the plate shown in Fig, 1 wherein- Fig. 6 is a section on line 6--6 of Fig. 5.
  • Fig. 7 is a section on line 1-1 of Fig. 5,
  • Fig. 8 is a'section on line 8 8 of Fig. 5.
  • Figs. 9 to 12, inclusive show a single plate formed according to a modification of my invention with the ladder rungs mounted thereon ready for mounting upon a car to form part of the end wall thereof wherein- Fig. v10 is a section on line 'l0-,l0 of Fig. 9.
  • Fig. 1'1 is a section on line I I-ll of Fig. .9.
  • Fig. 12 is a section on line
  • Figs. 13-16, inclusive, are similar to Figs. 5-8
  • each pair of major corrugation 2 and reinforcing rib 5 is figured as a beam between its points of support which are the corner posts of the car.
  • Fig. 17 shows the bending moment parabola Il and the section moduli line I8 between the points of support I9-I9.
  • the sction modulus line I8 is always above the bending moment parabola Il which shows that the beam is strong enough at all places to support the load.
  • I preferably also proportion the major corrugationg 2 and reinforcing ribs 5 so that the length of the center line of the metal of a cross section of the combined major ,corrugations and reinforcing ribs is substantially the same as any other cross section, thus' making the plate easy to form on reciprocating dies by equalizing the stretch and draw-in ofthe metal during the forming operation.
  • the end portions 8 of the major corrugations 2 are made deep enough to project between the ladder rungs I I, but not beyond the outer surface When the end portions 8 of the major corrugations 2 are about three inches deep and the end portions I2 of the reinforcing ribs 5 are one and one-half inches deep. the combined section modulus thereof is suiilcient to develop the ⁇ strength of the central portion of the four inch deep corrugation.
  • Figs. 5,- 6, '7 and 8, inclusive show a single plate similar to the plate shown on the end wall of Fig. 1 but with the end portions 20 of the major corrugations 2I shallower than the end portions 22 of the reinforcing ribs 23 and the ladder rungs 24 mounted upon the relatively shallow end portions 20 of the major corrugations 2l.
  • Figs. 9 to 12, inclusive show a single plate according to a modification of my invention wherein a relatively thin metallic plate is formed with a plurality of corrugations 30-3I with their opposite ends. 32 terminating into the plate which would be adiacentcorner posts of the car, as shown ,in Figs. land 2.
  • Some of the corrugations (preferably inpairs) merge together between their ends to'form :a lesser number of wider corrugations33, and preferably deeper corrugations substantially midway between the ends of the corrugations which, when applied to the car, would be substantially midway between .the corner posts of the car.
  • Some of -the first mentioned corrugations (shown as 38) are formed with shallow end portions upon which the ladder rungs 34 are mounted'so as to increase the end ladder clearance when; the plate is installed upon a car.
  • Figs. '13 to 16, inclusive show a single plate according to another modification of. ⁇ my invention wherein a relatively thin metallic plate is formed with a plurality of major corrugations 40 with their opposite ends terminating into vthe plate which would be adjacent the corner posts of the car, as shown in Figs. 1 and 2.
  • 'I'he plate is also formed with pairs of aligned shallower minor corrugations 4I-42 positioned between adjacent major corrugations I with their inner ends 43 terminating into the plate and with their outer ends M terminating into the plate suby stantially in line with the outer ends of the major corrugations.
  • the ladder rungs I5 are mounted upon the shallower minor corrugations to increase the end ladder clearance.
  • corrugated plates having a shallow corrugation, or a corrugation having ashallow portion to accommodate a ladder rung may be used as part of a side door for al railway car wherein such shallow corrugation or of cooperating beams extendablevbetween said frame members.
  • some of said corrugations being formed with end portions shallower than the end portions of the other of said corrugaltions and ladder rungs mounted upon said shallower end portions parallel therewith and which project beyond the other of said corrugations.
  • a wall for a railway car comprising a metallic plate adapted to be secured to oppositely disposed frame members of the car and provided with.a plurality of horizontally disposed major corrugations extendable substantially between the frame members and terminating into the plateadjacent said'frame members and' a pair of alined shallower horizontally4 disposed minor corrugations positioned between adjacent major corrugations with their inner ends terminating l into the plate and with their outer ends. terminating into the plate in line with the outer ends of the major corrugations and ladder rungs mounted upon some of said shallower minor corrugations parallel therewith and which, project outwardly beyond the major corrugations.
