Specification of Letters Patent.

Patented Get. 1 Z, 1916.

Application filed February 19, 1915. Serial No. 9,331.

.l e it known that I, \Vxi/rin: l Merrily, a citizen of the lhiited States, residing at thicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Pressed-Steel C-ar Ends, of which the following is a specilication.

y invention relates to an end structure for railway cars, particularly box cars, and more especially to an end made up of plates or panels of sheet metal pressed or otherwise formed with strengthening and rigidif ving corrugations; and the principal object of the invention is to provide a structure of this character comprising a plurality of su perposed plates or panels formed with corrugations which extend at an angle to each other, one set preferably extending horizontally across the end of the car from one corand the other corrugations extending vertically from the end plate to the sill; said corrugatimis constituting structurally crossed beams r arches giving the end strength and rigidity to withstand external shocks, but more particularly the stresses, shocks and pressures from the inside of the car due to shifting cargoes.

The invention has for further objects such other new and improved constructions, arrangements and devices relating to sheet metal car ends as will be hereinafter dc scribed and claimed.

The invention is illustrated, in a preferred embodiment, in the accompanying drawing wherein- Figure 1 is an end elevation of the superstructure of a railway box car provided with sheet metal corrugated reinforced cnd constructed in accordance with my invention, and Fig. 2 is a vertical sectional view taken on line 2-2 of Fig. 1.

Referring to the drawing, the end sill of the car is designated 10, the end plate 11, the roof 12, the flooring 13, and the corner posts 14.

The end structure, in the preferred embodiment shown, consists of three sheet metal plates or panels 15, 16, 17 formed with horizontal corrugatirms 18, 18, and two plates or reinforcing members 19, 19. formed with corrugations 9.1: which extend vertically, the panels being superposed upon the panels 15, 1G. 17 and secured thereto at intervals by rivets 21/ The panels 15, 16, 17 have their edges overlapped and riyeted to gether by rivets 22. The upper panel is secured to the end plate 11 by bolts 23. The lower panel 17 is preferably formed with an inturned. flange 24. which intervenes between the flooring of the car and the end sill 10 and is suitably anchored to the latter. All three panels 1?), 16, 17 are formed with angular flanges 25 which overlap and are secured to the corner posts 11. The panels 1!) are fastened to the end plate 11 by bolts 26. he attachment of the and structure to the framing of the car is prcferabty made more secure by means of gusscts 27 and tie bolts 28.

The corrugations 18, 18*, project alternately outwardly and inwardly and terminate within the edges of the panels, the corrugations preferably merging one directly into the other so that the center portion of the structure consists of Li. series of horizontal beams or arches one directly above the other. The corrugations taper or merge into the flat marginal portions.

The corrugati .)ns 2() are preferably deepest and widest atpoints below the center horizontal line of the end structure and taper gradually toward their extremities. Thus beams or arches are provided which cross the beams constituted by corrugations 18, 18, the thickest or deepest portions of which are in the lower portion of the end where the-cargo thrusts are likely to he heaviest.

The upper panel 15 is preferably formed with a door opening 29 closed by a sheet metal door 30 held in place by a locking bar 31. The door construction, however, is not claimed herein.

While 1 have described my invention in a preferred embodiment, it will be understood that modifications might be made without departure from the principles of the invention. The number of panels alight 0bviously be varied for example. Therefore I do not wish to lie/understood as limiting the invention to the precise constructions, ar-- rangcmcnts and devices shown except so far as the claims are expressly so limited.
