WALTER r. MURPHY, or CHICAGO, ILLINOIS.

METAL. END RAILWAY-CARS.

To all 'whom 'it may concern:

Be it known that I, WALTER I. MURIHY,

' a `citizen ofV the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and use ful Improvements in Metal Ends for Railway-Cars, of which the following is a speci-` cation.

My invention relates to the construction of railway cars, particularly box cars, and has for its object to provide a novel and improved metal wall, particularly end, structure for railway cars com osed of one or more metal sheets or panes, and provided with reinforcing and stiffening members or devices which may be formed or pressed in the sheet or sheets of metal of which the car is composed, whereby the said wall, while being light and inexpensive to make, will be capable of withstandin the heavy strains and pressures to which t e wall of a railway car is subjected when in service and whereby such strains and pressures are transmitted to the framework of the car.

strength is most needed, to-wit More particularly, the invention has for its object to provide a sheet metal wall structaking advantage of the fact th'at under the requirements of the 'Interstate Commerce Commission there need not be asmuch clear-I ance' between the ends of two railway cars near the center line of the cars as at the sides of the cars where the end ladders are placed'.`

A further obj-ect. of the invention is to provide a car wall, which, besides being more durable than 4the ordinary wooden structure, will stiften and 'reinforce the entire car body as' against weaving and other like stresses` tending to distort and strain the same'. The inventionhas for further objects such otliernewand improved constructions, arrangements and'devices in sheet metal car walls as willbe' hereinafter described and claimed. y

The inventiomis illustratedv in certain Speccation of Letters Patent.

preferred embodiments in the accompanying drawings,`whereinw Figure l is a view, in elevation, of the end wall of a car, showing the preferred form of construction Fig. 2, a sectional View taken on line 2-2 of Fig. l; i

Fig. 3', a sectional view on line 3 3 of Fig. 1; p

4, an elevation of the end wall of a car illustrating a modification of the structure shown in Figs. 1 to 3 inclusive;

Fig. 5, a sectional 'View taken on line 5-5 of Fig. 4:; and

Fig. (i, a sectional view taken on line (i4-6 of Fig. 4.

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

In the drawings, the end plate of the car is designated 25, the side plates 26, the corner posts 27, the end sill 28, and the flooring 29. It will be understood that my in vention has nothing to do with the general construction of the car. The wall structure hereinafter described might be used on cars of any ordinary type. 4 Figs. l to 3 inclusive show a construction consisting of one or more, preferably two,

.sheets reinforced bv diagonally extending reinforcing ribs which transmit stresses and pressure against the structure, through the truss member with which the structure is preferably provided, to the frame-work of the car. In Vthese iguresthe upper sheet designated 30 is formed with a pressed out rib or corrugation, 31 which extends diagonally across the sheet and is deeper and wider at the middle than at the ends. and with a plurality of shorter diagonal corru'- gations 372. The lower sheet 33 is formed with similar corrugations 31, 32a, which p referablv extend across the sheet in the opposite direction from the-corrugations of the upper sheet. The upper margin of the lower sheet extends back of the upper sheet and is secured thereto bv rivets 34. The lower edge of the upper sheet is bent'so as to forni an outstanding flange 35 which is preferably widest at the middle, tapering down toward its extremities. The upper sheet may he formed with angularly ,dis-` posed langes 36 to overlap the corner posts 27 and which may be secured thereto by means of bolts 37. The lower sheet 33 may have similar side {ianges 38 which, in a similar "manner, may overlap the corner posts 27 asV and be secured thereto. The lower sheet may also have an inturned flange 39 intervening between the end sill 28 and the fioorf ing 29 and secured therto by bolts 40.

A modified form of the invention is illustrated in Figs. 3 to 6 inclusive, wherein the end4 wall consists of two upper sheets 4.1 and 42 formed on their meeting edges with outstanding Hanges 43 and on their lower edges with outstanding flanges 4.4 and a pair of lower sheets 45 and 4:6 formed with flanges 47 on their meeting edges, the upper margins of the lower sheets being' flat and extending` back of the lower edges of the upper sheets at which point they are secured to the upper sheets by means of rivets 48. The outstandinn,r flanges 14 are preferably widest at their abutting ends and decrease in width toward their outer extren'iities. The flanges 42% and 47 are prufx'erably slieaved with U-shaped elements 19 and 5() as to make the joint between the sheets absolutely waterproof. The flai'zg'es 47 of the lower sheets shown as increasing in width toward the bottoni. This coi lotion pros-illes an increaseil re f .it for the lower part of the und which naturally subjected to the and pressures. The liangrcs greatest 44 are preferably secured to the flanges lr by means of angular gussets 5l. These gussets serve to combine the flanges est into a stift' ,unitary trusseouivalent in function to the truss member or flange ln this modi,- iication each sheet `is formed with an X corrugation and preferably with vert-ical corrugations 53 and horizontal corri'lgzitions 54. The function of the X eorrugation is to transmit stressses on the center portion of the sheet toits corners, that is to say, to the fran'iework of the car and the horizontal and vertical truss members. The horizontal and vertical corrugations stiften and reinforce the sheets against local thrusts. ln cach of the embodiments of the invention dis closed, trusses or reinforcing' members are iprovided which serve particularly to reiir force the center portion of the structure where reinforcement is most required. In each instance advantage is taken ofthe fact that, when utilizing the structure in the end wall, the center parts of the end ofthe car may project out farther than the side portions to which the end ladders are afiixed. It is to be noted that the number of reinforcing or truss members might be increased or diminished in either ;of the illustrated forms, and these members might be constituted by separate elements where they are shown as provided by the Hanging of the sheets. Obviously, also, the number of sheets, whichin one case is four and in the other two, may be varied as circumstances require.

Where the car is provided, as herein shown, with reinforcing -or truss members running in different directions, and each secured to or integral with the middle of the sheet metal structured the wall of the ear is not only stiff and strong in itself, so as to be capable of withstandirngr cargo thrusts, but it also serves to reinforce and strengthenthe framing of the car as against Weaving strains.

In the accompanying drawings andin the foregoing,r description is set forth the preferred embodiment of the invention, but it is obvious that one skilled in the art might make modifications thereof without depart ing from the spirit of the invention.
