PANY, OF NEW YORK, Y., A CORPORATION OF MARYLAND FRAME Application filed August 26, 1925. Serial No. 52,579.

This invention relates to side frames for railway car trucks and more particularly to an improved construction of side frames with journal boxes integrally connected at the ends thereof.

The principal object of my invention, generally considered, is the construction of side frames formed with journal boxes integrally connected at the ends thereof in such a mannor as to be separate from the main truss portion of the frame.

An object of my invention is the provision of an improved side frame for railway car trucks in which journal boxes are integrally formed at the ends thereof, the webof the tension member of said frame, however, not connecting directly with the journal boxes but passing above the upper inner corner of each journal box and merging with the Igorresponding web of the compression memstruction of side frames for railway car trucks in which the compression and tension membersthereof are formed generally of inverted U or channel shape in cross section with the webs of said members merging at the ends thereof without intersecting journal boxes integral with the frame, said journal boxes being connected with said members by flanges extending from said web portions.

' A further object of my invention is the formation of an integral cast steel side frame with journal boxes at the ends thereof, said frame involving compression and tension members of channel or U shape in cross section with the flanges of said members merging and forming continuations one of another near the journal boxes, the webs of said members, however, not connecting directly with said journal boxes. A still further object of my invention is the provision of cast steel side frames for railway car trucks in which the compression and tension members are'generally U shape in cross section with upper webs and depending flange portions, said web portions merging together over integral journal boxes a jacent the ends of the frames with the web of the tension member departing from the Another object of my invention is the 0011-" upper contour thereof near said journal boxes, whereby the flanges of said tension member are continued upwardly beyond the web portions thereof and curved to merge with the correspondingflanges of the compression member, said flanges below the web of the tension member connecting the integral boxes at the ends" of the frame and said connection being-additionally reinforced by substantially triangular transversely ex tending gusset portions.

Other obj ects and advantages of the invention relating to the particular arrangement and combination of the various parts, will become apparent as the description proceeds.

Referring to the drawings illustrating my invention, the scope whereof'is defined by the appended claims: 7

Figure 1 is a fragmentary side elevation of one end of a cast side frame for railway car trucks, a'portion thereof being shown in section.

Figure 2 is a plan view of that portion of the side frame shown in Figure 1;

Figure 3 is a detail cross sectional view on the line 33.of Figure 1.

Figure 4 is a detail cross sectional View on the line H of Figure 1. i Referring to the drawings in detail, like referencecharacters designating like parts,

there is illustrated one end of a sideframe 1 formed witha compression member 2, a tension member 3, and integral journal boxes 4. As will be understood by those skilled in the art, although only one end of the frame is illustrated, theother endfthereof is similarly constructed so that a symmetrical structure is formed, intermediate portions of the tension and compression members being spaced by strut or bolster column portions in accordance with the usual practice.

The compression member 2 and tension member 3 are both prefrably channel or U shape cross section. The compression member is formed with an upper web portion 5 and depending flange portions 6, said depending flange portions] being preferably provided with ribs or beading 7 along their outer lower edges. Likewise, the tension member 3 is formed with an upper web 8 and V edgesof these webs or gussets 16 preferablyslope from the connection 11 between the depending flanges 9 formed with beading 10 on the inner surfaces thereof along the lower edges.

The webs 5 and 8 of the compression and tension members, respectively, are continued outwardly from the central portion of the frame and are finally merged or connected together preferably over the central portion of the ournal boxes 4 along a curved portion 115 Inother-words, the web 5 ispreferably curved downwardlyover a journal box at each end thereof and the web 8 is preferably curved upwardly at the corresponding posi-' tions so that one web forms, in effect, a continuation of the other, as illustrated particularly in Figure 1. It will be noted that this merging between the webs 5 and 8 preferably occurs over the axis or center of each journal box. V

It will be noted that, contrary to the usual side frame construction, the web 8 doesnot intersect or merge with the journal boxes 4 but rather passes outwardly and upwardly above-the upper inner corner of each journal box to meet the*web'5 of the compression member above the roof of each box. The depending flanges 9, however, are preferably widened adjacent'theouter ends and merge with the inner side walls of each journal box, as indicated at 12. Likewise, the depending flanges 6 of the compression member 2 are preferably continued beyond the web 5 thereof and extended to merge with the roof 13 of each journal box, the outer edges thereof being preferably curved along a slope corresponding to the general direction of the end portions of the compression member to an upright position corresponding to the outer side walls of the journal boxes.

The depending flanges 6 of the compression member above the web 8 of the tension -member curve downwardly and around the outer corners of the usual triangular openings 14 between the compression and tension members and finally extend downwardly and inwardly to merge with the depending flanges 9 of the tension member, at 15. In-

asmuch as the flanges 6 and 9 are in line, one may be'considered as a continuation of the other adjacent the journal boxes, so that the web of the tension member diverges from and extends below the upper edge or contour of'said member adjacent the ends thereof, as will be apparent particularly from- Figures I 1 and 2 of the drawings.

For further 'rigidifying the connection between the compression and tension members and the journal boxes, a web or flange 16 is preferably provided over each journal box extending parallel with'therflanges 6 and 9 of the compression and tension members from the web f the tension member to the roof 13 of each journal box. The outer journal boxes are preferably additionally reinforced by laterally extending gusset por tions 18 between the innerside walls of the journal" boxes adjacent the upper edges thereof and the side edges of the web 8 or the upper edges of the depending flanges 9,

formed as "flaring extensions on the web of the tension member which curve downward- 1y toward the ends of the frame and merge with the roofsfof the boxes. Uprighttrian gular gussets 19. may-also-be provided ex tending laterally-from the depending flange portions 6 to the roof 13, of each journal box approximately in line with the inner brass lugs 20. I

It will be apparent that by virtue of the aforedescribed construction, a cast-side frame 1s provlded 1n which the main truss portion thereof is separate from the journal boxes at 7 each end thereof but castiintegral therewith.

That is the main truss portion, or the webs 5 and 8 thereof, does not merge directly with the journal boxes but is connected thereto by the depending flanges 6 from the compression member, the depending flanges 9 from the tension member, the auxiliary web portion.

16 between said depending flanges and the triangular gusset portions 18 and r 19. By such a construction secondary stresses adjacent the journal boxes are decreased, the journal boxes being rigidly connected atthe ends of the frame, however, by the various flanges, webs and gusset portions before described.
