T 0 all whom it may concern: I

Be it known that I, THOMAS NATHAN RUS- SELL, a citizenof the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Car End Constructions, of which the following is a specification,

My present invent-ion relates in general to car construction and more particularly to the'bodies thereof and has special reference to improvements in framing of such bodies.

The principal objects of my present 1nventi'on are the provision of improved means of connecting-the vertical and horizontal members constituting the frame of the car; the provision of improved means for connecting vertical metallic posts of angular cross section tohorizontal sills and horizontal mctallicend plates; the provision of improved means for stiffening and strength ening a carend and generally to nnprove, cheapen and simplify the construction of frames for car "bodies and such other objects as will hereinaftcrappear.

In attaining the foregoing objects and certainadditional advantages to be below disclosed, I have provided the construction illustrated in the accompanying drawings,

in which Figure 1 is a perspective view of the framing of a our end constructed in accordance with my present invention;

Fig. 2 is a perspective view of a supporting Shoe for the vertical posts of the car frame;

Fig. 3 is a section on the plane 3-3 of Fig. 1 illustrating the way in which the supporting shoe shown'in Fig. 2 is attached to the horizontal sill,

Fig. l is a section on the plane 4-i of Fig.1 illustrating more particularly the relation between the vertical post and its supporting shoe;

Fig. 5 is a plan view of the car roof shown in Fig. 1;

Fig. 6 is a perspective view of a portion of the framing of a car having.wooden horizontal sills and metal vertical posts;

Fig; 7 is a plan view of the modified form of supporting shoe used in connection with wooden sills as illustrated in Fig, 6; and

Fig. 8 is a perspective view of the shoe itself apart from the sills shown in l ln's. 6 and 7.

Referring now to Fig. 1, it will be seen that theframing of the car consists of horizontal clnmnel-shapcd sills 11, vertical Z- shaped posts 12, corner posts 13, and carlines 14, and longitudinal plates 16 by which the car lines are supported. The car frame rests on two center sills 40 which are supported in turn by the bolsters of the car.

It is desirable to strengthen the ends of tho car so as to prevent the ends buckling or being. knocked in or out. For this purpose gusset plates 18 are attached to the side plates 16 for the purpose of connecting the latter with: diagonal stays 19. These stays 19 are connected at one end to the gusset plate 18 and at the other end to the end carlines or end plates 14. One advantage of using a gusset plate 18 as an intermediary between the side plate 16 and the diagonal stay 19 is that the strain produced by the conncction between those two parts is more equally distributed along the side plate and also along the stay than would be the case if the diagonal stay was attached directly to the side plate 16. Thus not only is the side plate 16 engaged by a greater length of the gusset plate 18 than would be the case if the stay 19 was attached directly to the side plate 16 but also the length of stay engaging the gusset plate 18 is greater than would be the case without the use of such a gusset plate. To further strengthen the car end a stay :20 running parallel to the side plate 16 is arranged between the gusset plate 18 and the end carline or car plate 14.

The gusset plate 18 is preferably triangular shown. and provided with a lip 30 for engagement with the outcr side of the side plate 16. This lip takes the strain off the bolts 31 used to attach the gusset plate to the beam so far as tcnsional strains on the sta y 19 are concerned.

Further, the two stays prevent the buckling or bowing of the end outward and for this purpose the stays are preferably attached to points adjacent the center of the end car-line or end plate.

lVith regard to the improved means adopted for connecting the vertical posts 12 and the horizontal sills l1 particular reference is made to Figs. 2, 3 and 1. In Fig. 2 is shown the shoe which supports the vertical posts 12 which is preferably made in cast iron of such shape that the vertical post and horizontal sills are readily engaged therewith and there is little strain on the bolts, rivets or the like used for connecting the members to the shoe.

The horizontal sill 11 shown in Fig. 1 is channel shaped and arranged so that it presents on the inner side of the car a smooth vertical face against which the vertical face 21 of the shoe 22 rests. This face 21 serves to prevent the shoe moving outwardly under pressure from the inside of the car. In the vertical direction the shoe is supported by the sill 11 not only by means of its upper face on which rests the flange 23 of the shoe but preferably also by means of a bracket 24 riveted to the inner face of the sill 11 on which rests the horizontal flange 25 of the shoe. This flange or bracket 2t on the sill 11 is desirable as otherwise the inner part 26 of the shoe would have no support vertically beneath it and consequently an undue strain would be placed on the shoe and on the bolt or rivets connecting the flange 23 of the sill 11.

The connection between the post 12 and the Shoe is shown in Fig. at. For this purpose the shoe is formed with a Z-shaped vertical part 27, see Fig. 2, so proportioned that it will come in contact with the whole of one side of the Z-shaped post which it has to sup ort. This projecting part 27 is suitably at ached to the post 12 by rivets or the like.

then wooden sills are used instead of metal sills the construction on the shoe has F to be modified. In the first place the wooden sills are usually wider than the iron sills so that the necessity for a supporting bracket 24 is no longer present. A depending flange 28 is provided, however, for engaging with the inner face of the sill in order to prevent outward movement of the shoe thereby taking the strain of the bolts The flange 28 is formed with an aperture 34 through which is passed one of the bolts tying together the sills 30 and 87. The projection 27 is formed and attached to a Z-shaped post in exactly the same manner as the shoe illustrated in Figs. 2 and 4'.

I claim- 1. In a car frame, an upper structure comprising longitudinal side plates, a transverse beam, gusset plates attached to the horizontal faces of said side plates intermediate their ends, portions depending from said gusset plates attached to the vertical faces of said side plates, and diagonal members attached at one end to the gusset plate and at the other end to said transverse beam.

2. In a car frame, an upper structure comprising longitudinal side plates, a transverse beam, a triangular gusset plate attached along one side to the horizontal face of one of said side plates, a portion depending from said gusset plate attached to the vertical face of said side plate and a diagonal member attached to said gusset plate along another side of said side plate, the other end of said diagonal member being attached to one of said beams.
