June 10, 1941. A. CHRISTIANSON RAILWAY CAR Filed June 3. 1938 Q Q .Zhuantor: Ondaew Gin/shaman Patented June 10, 1941 UNITED STAT Es PATENT OFFICE RAILWAY CAR Application June 3, 1938, Serial No. 211,630

3 Claims.

The present invention relates to vehicle structures, particularly railroad passenger cars and, as one of its principal objects, is intended to provide means for splicing together the side sheets of the car side in a manner which gives the car exterior a smooth finish and at the same time reinforces the side frame to which the splice is made.

Further and other objects and advantages will become apparent as the disclosure proceeds and the description is read in conjunction with the accompanying drawings, in which Fig. 1 is a side elevational view showing the left half of one of the side frames for a car; and

Fig. 2 is a fragmentary, horizontal sectional view taken on the line 2-2 of Fig. 1, showing details of the upright members of the side frame, with intermediate portions of the side frame broken away;

For the purpose of complying with section 4888 of the Revised Statutes, one embodiment of the present invention has been selected, but obviously many modifications may be made without departing from the scope of the invention.

For the purpose of illustration, various portions of the underframe are indicated, including the center sill 26 (Fig. 1), one vestibule end sill 29,

, body end sill 30, one bolster 3| and one cross bearer 32.

The side frames which, for the purpose of this disclosure, may be considered as including the roof structure, although the latter will be described separately, include the side sills 21, belt rails 35, letterboards 36, side plates 31 and a plurality of vertical framing members including a body corner post 38, a plurality of side posts 39 and a non-articulated corner post 46. A sheet 41 is rigidly secured to the side frame so that the frame acts as a compound girder with the portion above the windows 42 acting as an upper girder and the portion below the windows 42 acting as a lower girder, the two together acting as a single girder with the upper girder constituting the top chord and the lower girder constituting the lower chord of the single girder.

The body end frame 23 includes the body corner posts 38, door posts 43, auxiliary posts 44, a body end sill 30, an anti-telescoping plate (not shown), and a end sheet 45 rigidly secured to the posts.

The vestibule end frame 23a, comprises vestibule end posts 41, auxiliary posts 48, a vestibule end sill 29 and a sheet 49 rigidly secured to the posts.

The roof is made up of a plurality of relatively heavy carlines 53, somewhat lighter carlines 54, and a plurality of purlines (not shown), with the roof sheet generally designated 56 and preferably 5 thick rigidly secured to the roof framing members.

The side posts 39 are arranged in piers to transmit the necessary horizontal shear between the upper and lower girder members. The portion of the side frame which lies between the bolster 3| and the body end sill 30 is subjected to relatively high horizontal shearing stress and it may, therefore, be reinforced, if desired, by pressed plates as best shown in Fig. 2. The main piers, generally designated 96 are placed between alternate windows 42 and each comprises a pair of opposed channels 91 to the outside flanges of which the sheet 4! is securely riveted. The lighter piers 98 consist of box section members 99 which are also riveted to the side sheet. Between certain of the main piers 96 and auxiliary piers 98 are vertical reinforcements I00 to stiffen the sheet.

Preferably the sheet 4| is formed in upper and lower sections, the upper section or letterboard portion extending from the side plate 31 to the belt rail 35 and the lower portion extending from the belt rail to the side sill 21. The horizontal splice is made along the belt rail and the vertical splices are made on the main piers 96 in a novel manner which not only permits the adjacent sheets to have a flush fit, but also actually reinforces the pier upon which the splice is made.

The vertical splice is accomplished by providing an inner splice plate Nil which extends between the opposed channels 91 of the pier and is riveted to both the channels 91 and the sheet by rivets 102. The splice bar llll is also riveted to the sheet 4i immediately adjacent to the splice by rivets I03 with the result that the construction provides an exceedingly strong joinder of plates.

I claim as my invention- 1. In a railway car, a side frame including a pier comprising spaced posts having vertical flanges lying in the same vertical plane and extending toward each other, and right angle webs lying in parallel vertical planes, a splice plate extending between two adjoining posts and in the region between the posts lying substantially in the plane of the flange of each post and overlapping the inner surfaces of said flanges, side sheets held in flush abutting engagement against the post flanges and the portion of the splice plate between the posts with the line of abutment intermediate the right angle webs, and

means for securing the splice plate to the flanges and to the abutting sheets.

2. In a railway car, a side frame including a pier comprising spaced posts having vertical flanges lying in the same vertical plane and extending toward each other, and right angle webs lying in parallel vertical planes, a splice plate extending between two adjoining posts and overlapping the inner faces of the flanges of said adjoining posts and being secured thereto to form with the posts a three-sided box girder, the portion of the splice plate lying between the posts being in the plane of the post flanges, side sheets held in flush, abutting engagement against the post flanges and the portion of the splice plate between the posts, and means for securing the sheets to the posts and the splice plate.

' portions of the plate and the flanges and through i the portions of the plate which do not overlap the flanges.

ANDREW CHRISTIAN SON.
