SIDE FRAME Filed March 1929 Qmxmtot IIIIIIIIIIII/IIII Ill/III] Patented Dec. 24, 1929 UNITED STATES PATENT OFFICE BYERS W. KADEL, OF BALTIMORE, MARYLAND, ASSIGNOR TO THE SYMINGTON COM- PANY,.OF NEW YORK, N. Y., A CORPORATION OF MARYLAND SIDE FRAME Application filed March 5,

This invention relates to side frames for railway trucks and, more particularly, to a construction involving an improvement in the strength of connection between such frames of the cast type and integral journal boxes at the ends thereof.

The principal object of my invention, generally considered, is to improve the general appearance of cast metal side frames 1ntegrally formed with journal boxes at the ends and consolidating in the main core the remforcing portions usually provided in the angle between the tension member and ournal boxes.

Another object of my invention is to'improve the connection between integral journal boxes and their associated frames by widening and downwardly convoluting the web portions of the tension member to provide hollow brackets between said member and the adjacent side walls of the box, the lower edges of said brackets preferably extending to the side walls of the box and meeting said walls adjacent the lower ends of the corresponding brass lugs, the side walls of said brackets being flared upwardly away from each other to form a construction V shape in cross section, the flanges-of said member at the widened portion of the web extending thereabove being maintained at a normal distance with respect to one another and joining with bifurcated web portions disposed in the normal plane of the web of the tension member, the width of said brackets adjacent the junctions with said boxes corresponding with the flange spacing to that the side walls thereof form, in effect, downward extensions of said flanges.

I A further object of myinvention is to pro vide a side frame with integral journal boxes, the roofs of said boxes being preferably beveled rearwardly of the front flange of the tension member with the web of the member sloping generally in line with the beveling of the journal box roof, the connection between the tension member, or junction between said tension and compression members, and journal box being reinforced by increasing the width of the tension member web and providing a hollowconvolution therebeneath, the

1929. Serial No. 344,443.

flanges of said member extending upwardly from that portion of the web in the normal plane thereof and disposed at a normal distance with respect to one another, the sides of said convolution adjacent the junction away from said box to finally merge into the normal portion of said web, the side flanges of said tension member extending upwardly from the web thereof but being undiverted from their normal positions, the sides of said bracket at the junction between the box and tension member being spaced to correspond with the spacing between the flanges.

Other objects and advantages of the invention relating to the particular arrangement and construction of the various parts will become apparent as the description proceeds.

Referring to the drawing illustrating my invention, the scope whereof is defined by the appended claims.

Figure'l is a fragmentary sectional View on the line 11 of Figure 2 looking in the direction of the arrows of a side frame and integral journal box embodying my invention.

Figure 2 is a fragmentary horizontal sectional view on the line 22 of Figure 1 look ing in the direction of the arrows.

' Figure 3 is a fragmentary longitudinal sectional view on the line 33 of-Figure 2 lookingin the direction of thearrows- Figure 4 is a fragmentary longitudinal sectional view on theline 44 of Figure 2, 1,0011, ing in the direction of the arrows.

Figures 5, 6 and 7 are fragmentary transverse sectional views on the correspondingly numbered lines of Figure 1 looking in the direction of the arrows.

Referring to the drawing in detail, like parts being designated by like reference characters, there is shown a side frame 1 of the cast type comprising a tension member 2 and a compression member 3 unitedat their ends and to integrally connected journal boxes 1, only a portion of one of which is i-llustrate d. Although only a fragmentary portion of the frame is shown, itwill be understood that the construction is an improvement in frames of the type illustrated and described in the Hankins Patent No. 1,637,696 of August 2, 1927, and that said frame has a compression member and a tension mem ber spaced at intermediate port-ions by struts or bolster guide columns, the tension and compression members converging at their ends and united together and to integral journal boxes. As those portions of the frame, not illustrated-,-are of wellknowlr construction, it is not deemed necessary to show any more than the novel features which will now be pointed out. I p v v In the Hankins patent above referred to, the connection between the tension member and each box was reinforced by a' pair of web portions spaced from the junction between the'web of the tension member and box and from each other, thereby necessitating a separate external core. the present instance, the connection between the tension member 2, which is preferably channel shape in cross section and comprises a lower web 5 and upstanding flanges 6, and the journal box f is reinforced by a hollow bracket 7 approximately V shape in cross section, as illustrated particularly in Figure 5. Said bracket is preferably formed beneath widened or expanded portions 8 and 9 of the web 5, said web being preferably extended tomeet the roof 10 of the box at the junction with the inner brass lug 11. Said web is not only increased in width or expanded, but is preferably increased in thickness to a maximum at the junction 12 with the roof of the boxto compensate for an aperture 13 formed by the bifurcation of the web 5 above the hollow bracket 7 which provides for core removal. The'bracket 7 is preferably formed by downi'vardly curving a web portion of the tension member to meet the side wall of the box at approximately or slightly below the lower end of the brass lug 1'1, the sidefwalls'of said bracket portion flaring upwardly and outwardly to join the expanded web portions 8 and9 in line with thefiangesti of said tension member which are maintained normally spaced with respect to one another, that is, unaffected byJthe flarin'g orexpanding of the normal web portion of the tension member. It will therefore be seen that the side walls and, I?! Qft 'e brack -1.7 rm in effect, do'wn'ii' ard extensions of the flanges 6' at and adjacent the junction with the corresponding side wall of the journal box 4:. The bracket or convolution 7 preferably tapers and decreases in depth and width to finally merge into the normal web portion 5 of said tension member, as illustrated particularly in Figures 1, 2and3,

The journal box is preferably beveled at its upper corners rearwardly of the front flan-get of the tension member or that portion of the frame after the union between the tension and compression members, said beveling being preferably produced by sloping the roof of said boxdfownwardly and outwardly from the planes of the inner walls of the brass lugs, only one of which is illustrated, said sloping preferably corresponding with the normal or general inclinationof the web 5 of the tension member 2, so that the tension member web forms, in effect, a continua"- tion of the sloping portion15 of the roof lOat the adjacent sidewall of the box.

From a consideration of Figures 2 and 55, particularly, it will be seen that the flanges 6 of the tension member are not diverted or flared away from one another to correspond with the flaring or' widening of theweb, but are extended over said web portion and the roof 10 of the box while normally disposed with respect to one another. From aconsideration of Figured, it will be seen that the sides 14 and 14: of thehollow bracket 7 meet the normally disposed web portions8 and 9 as downward extensions of the fianges G and inwardly of the outer edges of the widened portions 8 and 9 of the web 5. It will also be noted that although the web portion is thickened between the flanges 6 adjacent the aperture 13, yet those portions 8 and" 9'of the web beyond the flanges 6 are preferably of normal thickness, that is, they correspond with the thickness of the flanges and that of the tapering convolution or bracket portion 7.

It will be seen that those portions of the widened web 8 outwardly of the outer flange 6 of the tension member are slightly offset upwardly, as indicated at 16, with respect to the normal web portion on account of the box forwardly of thefront flange 6 of the tension member not being beveled like the rearward portion of the box, as'illu's'trated particularly in Figure 3, so that said web portion 16 is extended to meet the upper inner corner of the box at the portion thereof where the roofand inner sidewall meets at an angle of 90 degrees with. only the normal fillet therebe} tween. E xc'eptc for thisthfi'eren'ce, and the "fact that the side wallsof'the' box forwardly of the longitudinal center line are" tapered slightly and then disposed slightly closer t ogethenthe constructionr o'f the renamin e pe er and a p i e sides of the center line maybe as nearly idenal c From the foregoing description taken in connection with the accompanying drawing, it will be seen that I have improved the connection, strength and general appearance of east side frames with integral journal boxes by reinforcing the connection between the tension member and box by means of a bracket formed as an integral depending convolution or corrugation generally V shape in section beneath the normally disposed web portion of said tension member, said web portion'thereabove being widened and joining thesides of said bracket, the lower edge of said bracket preferably meeting the adjacent wall of the box adjacent the bottom of the corresponding brass lugs. The convolution or hollow connecting bracket is preferably corresponding in width with that of the tensionmember and spacing of the tension memberflanges but tapers or decreases in width away from said box to gradually merge into the normal web portion of the tension member. The flanges of the tension member or the side walls of the frame at the junction between the tension and compression members are preferably normally disposed with respect to one another and not diverted outwardly to correspond with the flaring or increase in Width of the tension member web. In this way the sides of the hollow bracket adjacent the journal box form, in effect, downward extensions through the web of the tension member of the side flanges thereof.

Although a preferred embodiment of my invention is illustrated and described, it will be understood that modifications may be made therein within the spirit and scope of the appended claims.
