VINTON E. SISSON, OF CHICAGO, ILLINOIS, ASSIGNO'R TO WALTERYP. MURPHY, CHICAGO, ILLINOIS.

Specification of Letters Patent.

Original application filed March 29, 1915, Serial No. 17,840. Divided and this application filed January 11, 1918. Serial No. 211,362.

To all whom it may concern:

Be it known that I, VINTON E. SISSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Steel Car Ends, of which the following is a specification.

My invention relates to an end structure for railway cars, more particularly box cars, and the principal object of the invention is to provide a sheet metal car end comprising a metal end sheet or end sheets formed with vertical or substantially vertical corrugations which are of substantially uniform width except at their extremities andmerge one into the other so as to provide a uniform reinforcement for substantially the entire area of the end wall of the car for the purpose of strengthening and rigidifying the same as against cargo thrusts and the tendency of the car to weave; the corrugations, being vertical or substantially so, acting also as posts to carry a part of the roof load- (when the end structure of my invention is applied to a box car).

A further object of the invention is to provide a construction for the car end whereby the stresses exerted against the corrugations are transmitted to rigidifying elements at the upper and lower edges of the car, and whereby the sheet metal end structure is made to directly support the longitudinal frame members of the roof.

A further object of the invention is to provide a construction for the end of a railway car, more particularly a box car, whereby the end sheets are connected to the longitudinal frame members of the car, particularly at the top, in such .manner as to rigidify the entire end of the car as against the tendency to distortion of the structure commonly known as weaving.

The invention has for further objects such other new and improved constructions, arrangements and devices relating to sheet metal end structures for railway cars as Will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in the accompanying drawings, wherein Figure 1 is a view, in elevation, of the superstructure of a railway box car provided with a sheet steel end constructed in accordance with my invention.

Fig. 2 is a fragmentary plan View of one end of the car with the roof boards removed.

Fig. 3 is a sectional view taken on line 33 of Fig. 2.

Fig. 4: is a fragmentary sectional plan on line lli of Fig. 1.

Fig. 5 is a vertical sectional view on line 55 of Fig. 1, and

Fig. 6 is a fragmentary section on line 66 of Fig. 2. I

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, 10 designates one-of the end sills of a railway box car. I prefer to employ a channel bar, or other structural steel member, having one or more horizontal flanges whereby such member has considerable lateral strength. The corner posts 11 of the car are preferably angle bars. The side sills are indicated at 1'2 and the side plates at 13.

The end structure comprises, in its preferred embodiment of the invention, a sheet steel panel consisting of two end sheets l l and 15 which extend from top to bottom of the car and are secured together at their meeting edges. The sheets are formed with substantially vertical corrugations, which terminate within the edges of the sheets, and which preferably extend substantially from the floor of the car to the roof. The sheet l i has a flat marginal portion 17 which extends back of the edge corrugation 16 of sheet 15 and is secured thereto by two lines of rivets 18 on opposite sides of corrugations 16*. The corrugations merge one into the other so that the structure has a sinuous configura tion in horizontal cross section as shown in Fig. 4:; and the edge 19 of sheet 15 is preferably curved so that it fits into the edge corrugation 16 of sheet 1 1, this arrangement making the structure waterproof along the junction between the sheets. The outer edges of the sheets are secured to the corner posts 11 by rivets 20. The lower edges of the sheets are riveted or otherwise secured to the end sill. The upper portions of the Patented. Aug. 12, 1919.

sheets are preferably bent over on lines corsecured together, as, for example, by a gusset plate 23, which latter provides a sup ort for the ridge pole 24:. The outer ends 0 the flanges are riveted to the side plates 13. Preferably the connection is made more rigid by means of gusset plates 25 riveted to the side plates and to the flanges 21. In order to further rigidify and strengthen the upper part of the end structure and the ad- ]olning portion of the roof, a structural steel beam, for example, a channel bar 26 may be arranged across the car from side to side. This bar is bent at the middle to correspond to the slope of the roof and its ends are sheared oil as indicated at 27 (Fig. 3) and rest upon and are riveted to the side plates 13. One of the bolts 28 which secure the ridge pole 2 1 to the gusset plate 23 extends through the channel bar 2 6, the outerleg and web of which are riveted to the

sheets

14, 15. If further rigidity is required an angular brace 29 may be riveted to the sheets just below the level of the eaves and its extremity secured to the side plates 13 by angle pieces 30. This angle bar, taken in connection with the channel member 26, provides a truss-like reinforcement for the upper part of the end wall structure of the car which holds the car in sha e and prevents distortion of the roof. 'l o further rigidify the upper part of the car structure as against strains known as weaving strains, I preferabl provide diagonally extending braces 31 anc ored at opposite ends to the flanges 21 and to the side plates 13 and preferably secured at intervening points to the purlins under which the braces extend.

It will be seen that the flanges 21, particularly when reinforced with the member 26 or the member 29, or both, serve the purpose of the ordinary end plate of the car.

Each ofthe corruguations 16 merge into the next corrugation so that the sheet metal panel consists, in effect, of a series of alternately oppositely rojecting ribs which 00- operate to strengt en and rigidify the end structure against cargo thrusts and also against the tendency of the car to weave and VghlilnflflllthQIIfiOlB, because of their subs an 1a y uprig t osition, su ort in art the roof load, whilih, a will ge unerstoodi may be an item of some importance when the roof is covered with ice or snow. 'With the corrugations merging one into the other, as shown, no one rib or corrugation may bend out without carrying the adjacent corrugations with it. For this reason also the end panel, if deflected under an extraordinary heavy thrust, will the more readily spring back .when relieved of this stress Any stresses on the corrugations are transmltted by such corrugations, acting as beams, to the upper and lower edges of the panel. The upper edge of the panel is rlgldlfied in orderto withstand these stresses and transmit them to the longitudinal frame members of the car by means of the constructions above described.

In order to reinforce and strengthen the end structure at the bottom I employ pref feraibly a structural steel sill such as the channel sill shown, to which the end sheets are riveted so that this member will take the stresses transmitted by the corrugations to the lower edge of the sheet. In order to further rigidify the lower part of the end structure as against cargo thrusts, which are particularly severe in the lower part of the car where the heavy lading is placed, the end may be provided with a flat steel sheet 32 arranged on the inside of the

end sheets

14 and 15 and riveted to each inturned corrugation thereof by rivets 32*. Preferably the lower edge of the sheet metal element 32 is formed with an inturned flange 33 which extends under the flooring 34 of the car so as to provide a grain -proof joint between the end structure of the car and the floor. Thls flange also gives additional rigidity to the lower part of the end structure.

The corrugations 16 are preferably, though not necessarily of varying lengths so that their upper ends correspond in al1nement with the slope of the roof. 35 is an end fascia plate. The roof boards of the car are indipated at 36 and the metal roof sheets at 3 While I 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. Therefore I do not wish to be understood as limiting the invention to the precise constructions, arrangements and devices shown anddescribed except as the claims are specifically so limited.
