. Specification of Letters Patent.

Patented Nov. 23, 1915.

Application filed December 28, 1914. Serial No. 879,248.

which the following is a specification.

This invention relates to metal .carlines for freight car roofs, and particularly to the end connections thereof.

' The invention consists in a pressed steel bracket-member for connecting the ends of a plates of the car. I I I Carlinesare subjected to bending stresses throughout their length due to the weight of the-roof, and to combined bending and twisting stresses at their ends caused by the continual straining and distortion of the car frame in service. The carline end connections to the side walls of the car must be such as to withstand'these stresses? Rolled dies, jigs, templets, and similar tools are required for making a complete line of sizes of pressed steel carlines to fit-all cars it the end connections are made integral with the body portions.

"The object of this invention is an end bracket connection for a, metal carline which is strong enough to resist the bending and twisting at the en'dof the carline,,wh1ch is light in weight and which takes up but little room.

A further object is an end bracket connection which is adapted to be secured to the ends of pressed steel or rolled metal carlines of difierent lengths,'whereby the body portion for each diiierent length of carline can be formed with the same tools, and special dies for each different length'of carline are dispensed with. 1

Further objects of the invention appear hereinafter in connection with the descr ption of the embodiment of the invention shown. in the accompanying drawings; and

what; the invention consists in is particularly set forth in the appended claims.

lathe drawings, in which the same'characters designate like parts in the several \IGWS, Figure 1 1S=fl plan View" of the end of ,a carline and part of a side plate of a freight car, "howing a bracket connection embodying the invention; Fig. 2 is a side view of the end of the carline and bracket connection shown in Fig. 1, the side plate being shown in cross-section; Fig. 3 1s a top or plan view of the bracket connection; and Fig. 4 is an inside face View of the same, showing the carline in cross-section.

The carline 11 shown in the drawings is channel or U-shape in cross-section, with of its side walls. The carline may be rolled, or pressed from sheet metal, and its ends are outturned lateral flanges 12'along the tops I cut ofl to make its length slightly shorter than the distance between the inside faces of the side plates of the car for which it is intended.

A bracket connection 13, which conforms in shape across its middle to the under side of the carline at its ends, is riveted to each end of the carline. The bracket connection has flat top walls l i-which support the lateral flanges 12 of the carline, and a fiat end wall 15 which is riveted to the side plate 16. The end wall is wider than the width of thecarline, and the rivets for securing the bracket to the side plate are spaced apart sufficiently to afford a firm and substantial connection between them. The edges of the 'top walls lei and ends of the end wall 15 are turned downward and inward, forming marginal flanges 17 which extend across the angle between the top and end of the bracket and stiffen its corners. The flanges '17 and U-shaped middle portion of the bracket 13 give it an effective form to resist bending and twisting.

The invention is not restricted to the precise .forms and dimensions of the parts shown and described.

lVhat I claim as my-inve'ntion is as fol lows:

1. A carline'having a channel-shape body portion and end brackets secured thereto, to, each of said brackets having a top wall conforming throughout its length to the under side of the body portion of the carline and spreading laterally outside of the latter y at its end, and an end wall transverse to thesaid body portion, and inturned flanges along the side edges of the top Wall and ends of the end Wall connecting them across the outer corners of the bracket, whereby said carline is adapted to be embodied in existing cars ithout removing the roof.

2. A carline having a channel-shape body portion and end brackets secured thereto, each of said brackets having a flat top ,wall gradually increasing in Width from its inner to its outer end and provided with a middle depression conforming to the under side of the carline and an end Wall transverse to the carlin and coextensive with and depending Walls at the outer corners of the bracket, and

means for connecting said bracket to the of December, 19H.

side plate arranged in the spaces between said inturned flanges and middle depression.

3. An end bracket for the carlines of freight cars, said bracket having a top wall and an end Wall meeting at an angle, said top Wall having a channel formed in its middle extending through the end Wall for stiffening the bracket vertically under the end portionof a carline, said top wall being wider than said carline at the juncture with the end Wall for stiffening said bracket laterally,

and edge flanges turned in along the edges of the top and end Walls and forming vertical'braces between theedgesiof said top and end Walls and forming vertical braces be tween the edges of said top and end walls for stiffening said bracket against twisting.
