A CORPORATION OF LEAPJYLAND SIDE FRAME Application filed February 27, 1929. Serial No. 343,066.

This invention relates to side frames for railway car trucks and, more particularly, to improving the strength of connection between said frames 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 integrally formed with journal boxes at their ends and consolidate in the main core the strengthening ribs or brackets generally provided adjacent the junctions between the frame and boxes, thereby doing away with reinforcing flanges at said junctions.

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 of the tension member for its entire width to provide a hollow bracket bet-ween said the side walls of said bracket being flared upwardly away from each other to form a construction V shape in cros section, the flanges of the member at the wioened portion of the web being correspondingly outwardly flared or convoluted to join with the edges of said web.

A further object of my invention is to provide 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 downwardly convoluting it for the full width thereof, the flanges of said member being outwardly convoluted or corrugated adjacent the junction with the box to meet the side edges of the widened portion of said web.

A still further object of my invention is to provide a side frame and integral journal box construction in whicn the connection with the box is rigidilied and all strengthening ribs or brackets consolidated in the main core, thereby eliminating flared flanges at the junction of the tension member and box, this being accomplished by increasing the width of the tension member web and forming a depending V shaped corrugation in said web for preferably the full width thereof, the side flanges of said tension member being diverted or flared outwardly to the outer edges of said convoluted portion of the web.

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 of one end of a side frame and integral journal box embodying my invention, said section being taken on the line 11 of Figure looking in the direction of the arrows.

Figure 2 is a transverse sectional View on the line 2--2 of Figure 1 looking in the direction of the arrows.

Figure 3 is a fragmentary horizontal sectional view on the line 33 of Figure 1 looking in the direction of the arrows.

Figure 4 is a fragmentary longitudinal sectional view on the line ir-4E of Figure 3 looking in the direction of the arrows.

Figure 5 is a fragmentary perspective view of a portion of the front of the box and the tension member adjacent the junction between said box and member.

Figure 6 is a fragmentary perspective View of the back of the box and a portion of the tension member adjacent the junction between said box and tension member.

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 united at their ends and to integral journal boxes 4, only one of which is illustrated. Although only a fragmentary portion of the frame is shown, it will be understood that the construction is an improvement of the type of frame illustrated and described in the Hankins Patent No. 1,637,696 of August 2, 1927, and said frame has a compression member and a ten sion member spaced at intermediate portions by struts or bolster guide columns, the ten sion and compression members converging at their ends and united together and to in tegral journal boxes. As those portions of the frame, not illustrated, are of well known construction, it is not deemed necessary to show any more than the novel features which will now be pointed out.

ln'the Hankins patent above referred to, the connection between the tension member and each box was reinforced by a pair of web port-ions spaced from the junction between the web of the tension member and box and from each other, thereby necessitating a separate core. In the present case, 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 bracket 7 approximately V shape in cross section, as illustrated oarticularly in Figure 2. Said bracket is preferably formed by increasing the width of the tension member web adjacent the junction with the journal box and downwardly corrugating said web for the entire width thereof, the corrugation extending away from the adjacent wall of the box and gradually decreasing in depth and width to finally merge into the normal web of the tension member, as illustrated particularly in Figures 1, 3 and 4.

The journal box is preferably beveled at its upper corners rearwardly of the front flange 6 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 box downwardly and outwardly from the planes of the inner walls of the brass lugs 8 and 9, said sloping preferably corresponding with the general inclination of the web 5 of the tension member 2, so that the tension member web forms, in effect, a continuation of the sloping portion of the roof at the adjacent side wall of the box.

For further reinforcing the connection between the frame 1' or the tension member 2 thereof, and the journal box 4, the flanges of the tension member are sloped outwardly or correspondingly convoluted to meet the side edges of the widened portion of the web so that outwardly extending hollow embossments or corrugations are also provided in the flanges of the tension member, said corrugations being greatest adjacent the junction between the tension member and the roof of the box and decreasing or tapering both ways to finally merge into the normal planes of the flanges of said tension member, as most clearly indicated at 10 and 11. This construction obviates the necessity of external gusset flanges and substitutes outstanding hollow brackets or convolutions which are produced by the main core, thereby avoiding the necessity of separate cores and facilitating the manufacture of the frame.

The sloping or tapering portion 10 of the tension member or frame flange 6 over the forward or outer portion of the box may correspond generally with the corresponding portion 11 over the inner or rearward portion of the box, except that the forward portion of the box does not have the edges beveled like the rearward portion, as shown most clearly in Figure The beveling 12 adjacent the junction between thebox and tension member may extend between the flanges 6 of the ten- QlOIl member as well as rearwardly thereof. The constr ction adjacent the outer side wall of the box may correspond, but in the present embodiment is shown as of somewhat differentformation, in that in addition to being beveled downwardly and outwardly, the cor ners prod ced where the walls 13 and 14 of the outer br ss lug 9 and the outer side wall 15 of the box meet the beveled portion are cut off by planes angularly disposed with one another to provide the portions 16 and 17 sloping, not only downwardly and outwardly, but toward each other as well. This construction improves the eneral appearance of the frame and results in a slight economy in material and improvement in the strength of the box adjacent the outer brass lug. The inner brass lug 8 may be formed to correspond generally with the outer brass lug 9, but in the present embodiment is shown as provided with parallel side walls 18 and 19 and an inner side wall 20, the upper end of said inner side wall being deflected outward, as indicated at 21, to meet the beveled portion 12 of the box at approximately right angles.

From the foregoing description taken in connection with the accompanying drawing, it will be seen that l have improved the construction, strength and general appearance of east side frames with integral journal boxes by rein forcing 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, in the web of the tension member where said web is widened at the junction with the box, the lower edge of said convolution preferably meeting the adjacent wall of the box at the bottom of the corresponding brass lug. he convolution or hollow connecting bracket is preferaoly wider than the normal idth of the tension member at the junction with the box, but tapers or decreases in width away from said so}; to gradually merge into the iormal web portion of the tension member. The flanges of tee tension member or the walls of the frame at the junction between the tension and compression members are diverted outwardly to meet the side edges of the widened portion of the web ano inwardly of the corresponding Sl'tlt wall of the box to meet the roof of the box, thereby resulting in a further improven'ient in strength of connection between the side frame and box. The aforedescribed construction results in consolidating in one main core all strengthening ribs and brackets, thereby facilitating the manufacture of the frame.

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.
