Specification of Letters Patent.

Application fi1ed November 8, 1914. Serial No. 870,584.

To all whom it may concern:

Be it known that I, THOMAS A. DoonnY, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Metallic Car Ends, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part ofthis specification, in which Figure 1 is a front elevation of a metallic car end illustrating the'preferred form of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a detail of a cross section taken on line 33 of Fig. 1. Fig. 4 is a detail showing a vertical section taken on line H of Fig. 3. Fig. 5 is a detail illustration of a cross section of a modified form. Fig. 6 is a detailshowing a vertical section of said modification taken on line 6-6 of Fig. 5. Fig. 7 is a detail illustrating a cross section taken on line 77 of Fig. 1.

My invention relates to metallic car ends which are intended for use on box cars, the same being designed as either a part of the original construction of the car, or as a repair end which may be supplied to ordinary box cars in which the end has been broken.

The purpose of the invention is to provide a very strong and stable end construction which may be manufactured and installed very economically, and which may be easily repaired.

In the use of metallic car ends, and particularly those forms in which transverse corrugations are provided so as to stiffen the end horizontally, it has been observed that the metal is likely to fail adjacent the corner posts or between the corner posts and the ends of the corrugations which terminate on or short of the corner posts. These failures are due to the fact that a certain area of flat metal is left at the ends of the corrugations for attachment to the corner posts or for the formation of the inwardly turned flanges by which the sheet metal is attached to the frame members of the car. Frequent failures are found to occur at the point of junction of the sections, to prevent which various expedients have been resorted to to reinforce the structure at the line of junction, all of which increases the cost of construction. It is my. purpose, therefore, tmprovide a form of car end construction Patented Dec. 19, 1916.

which is free from these various insufii- I ciencies, and this I accomplish by the provision of corner posts of special form and the use of sheet metal sections having corrugations which extend clear to the marginal extremities of the sheets andlwhich are secured to the corner posts.

Referring now to Figs. 1, 2, 3, 4, and 7,

wherein the preferred form of my invention is illustrated, it will be understood that 1 represents the end sill of a car, 2 a side sill, and 4 the longitudinal side framing members. I supply the corner post 5, which is in'the form of a cast or pressed bar member, formed at its lower extremity with the flanges 6 which are adapted for attachment to the underframe members, and at its upper extremity with the-bracket 7 or similar portions which afford attachment for the side and roof framing members.

As will be seen in Fig. 3, the corner post is of general L-shape in cross section, having the front member 8 and the side member 9. The front member 8 terminates in a sinuous flange 8, and the side member 9 is provided with an inwardly directed sinuous flange 9. One or more sections of sheet metal 10 may be used. These sections are sinuously corrugated across their entire width, the corrugations being regular and on the same center. The corrugations may be formed in this sheet either as a part of the original rolling process, or they may be pressed cold into this conformation. This is a signal advantage over the manufacture of corrugated sections in which the corrugations terminate short of the edges of the sheet, as it does not require reheating of the metal, and the metal is not stretched, and consequently weakened, as is frequently the case when the metal is hot pressed into special shapes. The contour of the fiangesB and 9 is such as to conform to the outer and inner sides respectively of the sections 10,

there being a clearance between the conorder to compensate for any inaccuracies in v the castin and to insure a close and snug.

joint. W en the sheet metal sections are placed in position, the flange 9 laps behind the edge of the sheet metal, and the flange 8 lies upon the outer side of the sheet metal, thus clamping the edge of the section. The sheet metal is fastened to the flange 8 by rivets 11 which are seated 1n the tops of the outwardly convexmg corrugations. This disposes the heads of the, rivets on the inside of the car in the concave corrugations, and being thus inset, there 1s no danger of their comin in contact with the car 0, a very desira le arran ement especial y in the carrying of exp oslyes which might be discharged by concussion imparted to them by a rivet truck on the exterior of the car.

As will be seen from Figs. 3 and 4, the portion of the front member 8 intermediate the flange 8 and side member 9, is slightly oflset'from the flange 8, thus providing a vertical channel 12 on the outside of the section. This channel provides a runway for any water which might work through the joint between the flange '8 and the sheet metal. This water will flow downwardly and escape through a suitable opening at the bottom. This construction, therefore, protects the inner joint between the inner flange 9 and the edge of .the section against weather, and forms a practically impervious 'oint. J In Figs. 5 and 6 is illustrated a modified form in which a sinuous liner plate or angle member 14 is employedinstead of the flange 9. In this form, the sinuous flange 8, section 10, and liner plate-14 are all secured together by the rivets, and the front member is formed with a shoulder 15 against which the inner edge of the sheet metal abuts and upon which the edge of the liner plate lies, overlapping the edge of the sheet metal.

Where the different sections 10 are joined together, they are overlapped so that the marginal corrugations nest together and riveted through at the top of an outwardly convexing corrugation. When the end is in place, the side sheathing of the car is suitably secured to the side member 9, as illustrated in Figs. 2 and 5.

This construction is equally adaptable to a car end in which the corrugations are disposed "ertically instead of transversely. In this case, the marginal members of bar material, instead of being corner posts will be formed as portions of the end sill and fascia, which will engage the corrugated top and bottom margins of the vertically disposed sections.

From the foregoing, it will be understood that this construction forms a very strong and very stable car end which will elfectively resist the Weaving movements of the car body, and which is free from Weak aaoaeae areas. The continuous corrugations, extending as they do from margin to margin of the sheet metal, and being secured to the specially formed marginal members, provide a specially rigid and thoroughly reinforced structure.

I am aware that my invention may be incorporated in various forms otherthan those herein shown and described. Consequently, it is not my intention that my invention be limited to these specific forms, but that it cover all other forms and other changes and modifications properly within its spirit and scope.
