2 Claims. (Cl. 105 377) This invention relates to cover plate assemblies for railroad freight cars, and more specifically to removable sectional cover plates constituting a roof for a gondola or similar open top freight car.
One of the objects of the invention is to provide a cover embodying a central and end panels, each equal in length to approximately one-third the length of the car, the latter having overlapping end sections thereon to effect a Water-shed between the panels, yet accommodate the ready removal thereof.
Another object of the invention is to provide locating dowels in the base of each panel and latch mechanisms therefor to accommodate the assembly and removal of the panels from the upper edges of the side walls of the freight car.
Another object of the invention is to provide a plurality of vertical stanchions on the cover plate section to'` accommodate the stacked relation of the plates when in storage.
Another object of the invention is to provide hooks near each corner of each panel to facilitate the elevation or lowered position of the panels. v
Further objects of the invention reside in the provision of a cover for an open freight car which is light in weight, sturdy of structure and designed to accommodate progressive loading of segmental portions of the car by lowering the cargo therein coincident the assembly of thecover plates. n l
Other objects and advantages more or less ancillary to the foregoing, and the manner in which all the various objects are realized, will appear in the following description, which considered in connection withthe accompanying drawings, sets forth the preferred embodiment of the invention.

pin, the section being taken on a plane` indicated 'by the line 10 10 in Fig. 9.
Referring first to Fig. l, the cover assemblycomprises` a pair of removable end panels, A and B, anda similar center panel C. The panels are formed from arcuate sheet metal plates 10 having a plurality of spaced lineal beads 11 pressed in the face thereof and are supported by transverse arcuate channel irons 12 disposed'inspaced. relation with each other throughout the lengthof each panel. The channel irons 12 constitute roof beams and are reinforced by secondary. angle iron sections .13 be tween the angle irons 12 in aligned relation witheachA other throughout the length of the panels. The ends of` the channel irons 12 are welded to supporting rails 14 embodying lineal webs 15, depending flanges 16 on the outer edges thereof, upwardly directed ilanges 17 and angularly disposed inner flanges 1 8 on `the upper edges of the flanges 17. The plates `10 arewelded to theupper face of the flanges 18 and the ends ofthe upper tianges of the channel irons 12V are cut away to provide a recess for the flange 18. v l
The inner ends of the panels A and. B` areformed with channel iron 19 welded to the outer dependingleg of a channel 12. The web 21 of the channel 19. is foi-med` with a second foreshortened leg 22. Each end of the panel C is provided with a channel 23 -havingaweb l25 and aA foreshortened leg 24 within the channel 19.V 'Ihe upper face of the -ange 25 and the lower face ofthe leg 22 are positioned to provide a clearanceindicated by the arrows D (Fig. 3) when the panel sections A and-C and B and C are in assembled relation on the, upperedge,-
of the side wall of the gondola car. As. is. seen.. in Fig.V 3 the adjacent ends of the panelsare spaced apart .from one another longitudinally of the car. vThis structurenot. only provides a water-shed for *the joints-betweeuthe center and end panels, but also affords` ventsto.facilitate. the circulation of air through the car. Y
As will be seen in Fig. 5, the outer ends ofthe panels" A and B are provided with vertical walls 26 having outwardly directed webs 27 thereon and depending/anges 28 on the ends thereof. The flanges 28Y are spacedfrom the outer faces of angle irons 29 (shown in rdot-dash lines), which are welded to the upper `edgc vof the 'side' walls 30 of the gondola car. The corners of 'thefend panels A and B are reinforced by angle irons 31 and 32 welded to the'upper face of the webs27 of the 'end walls"- 2'6 and the web 15 of the side rails 14.; Theangle irons '31 and 32 are spaced outwardlyV from the; flanges/28 fof the end walls, and 16 of the side walls 14, to provide guide plates for the panels A and B when they are lowered in position preliminary to the adjustment of the panels with dowel pins 33 in seated engagement in keepers 34 on the sides of the gondola angle iron rim 29.
The dowel pins 33, as shown in Figs. l and 9, are mounted in the center of the supporting rails 14 and are formed from cylindrical bar stock with tapered ends 35 to guide the panels in openings in the angle irons 29, and semicircular sleeves 34 may be welded to the lower face of the angle irons 29. The dowel pins are supported in position by gusset plates 36 welded to the inner face of the upper portion of the pins and to the anges 17 and webs 15 of the supporting rails 14. The pins are further supported by triangular gusset plates 37 welded to the upper portions of the pins and to the Webs 15 of the rails 14.
The panels A, B and C are provided with vertical plates 38 in the medial axes of each end thereof, each having a lateral liange 39 on its upper end for the support Patented May 2s, 1961 of segmental running boards 40, indicated in dot-dash lines in Figs. 3 and 5. When the running boards are secured to anges 39, as -by the nuts and bolts indicated in `Figs. 3 and 5, and with their adjacent ends spaced apart from one another by a shorter distance than the distance betwen the ends'of the roof .panels all, as shown in Fig. 3, the running boards and plates 38 serve to maintain a clearance between the ends of the adjacent roof panels and thereby provide the spacing necessary for circulation of air into and out of the car between the ends of the roof panels. The plates are provided with hooks 41 to which a cable or chain fall may be attached to lift the plates off of the gondola.
The panels A, B and C are locked on the angle irons 29 by clamps (Figs. 6 and 7) each comprising a pair of spaced vertical plates 42 welded to the web 15 and flange 17 in the center thereof. The plates 42 are cross drilled with aligned openings therein, the inner openings being provided for a draw pin 43 retained, .when assembled, by a chain 44 afliiedA to the flange 17 and a cotter pin 45. A pin 46 in the Outer opening constitutes a fulcrum yfor a steel strap 47 ha'ving the upper forward end thereon bent downwardlyrover- 4the xed pin 46 in the plates 42, and the rearward end thereof being looped downwardly and outwardly Vto underlie the pin 46. Thefree outer end of the strap is bent downwardlyand inwardly to form a hook 48 adjacent a boss 49 on the angle 29 of the supporting rail 14. When it is desirable to remove the panels, the draw pin 43 is removed, the strap 47is moved outwardly, then swungupwardly about the pin 46, as shown in dotted lines in Fig. 8, until the strap 47 lies parallel and adjacent tothe ange 17.Vv Y
A, The WebsV of the supporting rails 14 have a plurality of spaced invertedV bars 50 welded thereon. The V bars are of a uniform size and the height thereof isv no greater than the dimension from the bottom of the supporting railsl to the upper face of the running boards 40. These bars 5,0 on one panel serve as supports on which another panel may restwhen the panels are stacked.
The panels A, B and C are each provided with hatch covers 51 for the inspection of the cargo within the car.y
' From the foregoing, it will be seen that one or all of the cover panels may be removed, the cargo loaded in the freight car vand the end and center panel positioned progressivelyover the cargo as it is loaded. Such procedute is particularly advantageous when the car is loaded duringa rain or snowstorm. Y Y
Although the foregoing description is necessarily of a detailed character, in order that the invention may be completely set forth, it is to be understood that the specific terminology is not'intended to be restrictive or confining,
andthatvarious rearrangements of parts and modica# tions' of detail maybe resorted to'without departing from the Scope or spirit of thev invention as herein claimed,
