SIDE FRAME.

Application filed March 29, 1926. Serial No. 88,189.

This invention relates to side frames for railway car trucks and especially to such frames having journal boxes integral therewith.

The principal object of my invention, gen crally considered, is the provision of cast integral side frames in which the members thereof are designed with respect to their cross sections and arranged with respect to each other so that great strength in proportion to the weight thereof is secured.

An object of my invention is the provision of a east side frame for railwaycar trucks in which the members thereof are so designed and the sections thereof are so varied that the most economicalcross sectionsare employed in the various positions on the frame, and, for that purpose, the cross sec tion of at least one of said members changes 29 both in strength and form between the ends thereof whereby the frame is lightened without sacrificing necessary strength and .con-

venient making of the mould for the frame and positioning of the cores therein is provided for.

Another object of my invention is the provision of a east side frame for railway car trucks formed with a compression member, the iptermediate portion of which is prefer- 30 ably channel shape with an upper web anddepending flanges on either side thereof and the end portions of which are gradually changed to I or T shape, a tension member, the central portion of which is box shape and preferably formed with a central or intermediate upright web and the end portion of which are formed substantially or star shape in cross section, the upright web of said star section, however, being preferably provided with transverse flanges at the upper and lower edges thereof.

A further object of my invention is the provision of a cast side frame for railway 'car trucks formed, with compression, tension 45 and bolster column member's, said bolster column members spacing intermediate portions of the compression and tension members and merging therewith, said frame being formed with a bolster opening framed by said members, the compression member above the bolster opening being formed channel shape in cross section, the tension member beneath the bolster o ening being preferably box r dou le ox s pe in cross section, the bolster columns being preferably 56 T shape in cross section, said compression member uniting with the tension member and with journal boxes at the ends of the frame, said frame being preferably I or T section above the journal boxes, the portions of the tension member diagonally dis osed between the journal boxes and the ower corners of the bolster opening being formed for portions of their length by continuing the section under the bolster opening,-said section, however, being reinforced by ribs or T sections rising from the upper web of the box section.

A still further object of my invention is the provision of a cast side 'frame for railway car trucks formed with compression and tension members and bolster column or strut members spacing intermediate portions thereof, said tension member being formed substantially box shape in cross section where it joins the lower portions of the bolster columns, which box section preferably extends outwardly and upwardly beyond said bolster columns with the side webs of said box section terminated before the tension member reaches the journal boxes, an intermediate upright web being provided extending from journal box to journal box as part of the section of the tension member, the ends of said web, where it joins the journal boxes, being referably bifurcated and connected to said journal boxes approximately at the junctions between the inner walls thereof and the inner brass lugs, the upper web of the box section, beneath the bolster opening, being continued as an intermediate transverse web of the diagonal end portions of the tension member and extended to the journal boxes.

Other objects and advantages of the invention relating-to the specific arrangement and combinat on 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 claims:

Figure 1 is a side elevation of a east side frame for railway car trucks embodying my invention, a portion pf said frame being shown in vertical section.

Figure 3 is a vertical cross sectional view on the line 3-3 of Figure 1 looking in the direction of the arrows.

Figure 4 is a vertical cross sectional View on the line 44; of Figure 1 looking in the direction of the arrows.

Figure 5 is a fragmentary sectional View on the line 5-5 of Figure 1 looking in the direction of the arrows.

Figure 6 is a fragmentary sectional view on the line 66 of Figure 1.

Figures '7 and 8 are detail sectional views on the correspondingly numbered lines of Fi ure 1.

fieferring to the drawings in detail, like parts being designated by like reference characters, there is shown a east side frame 1 which, in the embodiment illustrated, comprises a compression member 2, a tension member 3, bolster column guide or strut members 4 and journal boxes 5, The compression and tension members unite at the ends thereof andt-he journal boxes 5 are preferably integrally connected thereto at the ends of the frame. intermediate por tions of the compression and tension members are spaced by the bolster guide members 4 which are shown as integral therewith.

The various frame members are preferably formed, as illustrated, of varying cross sectional configuration in order to secure econorny of material without sacrificing the reqlln the present em: bodiment, the compression member 2, over the bolster or window opening 6, formed between the compression, tension, and bolster guide members, is formed of inverted ll shape or as a channel. with an upper web *5 and depending flange portions The lower edges of said flange portions are preferably formed with inwardly extending ribs or heading 9, as shown most clearly in l igure 3,

After extending beyond the bolster guides and a portion oi the distance between said guides and the journal bones, the cross secehang tion of the compression member changes gradually so that, over boxes, the sect on is Subsiant with an upper c and meeting the root 1 substantial position where it WILL: boxes 5.

The web oi adjacent the journal b reel 11 of each Leeaeee ing the flange 10 without other radical change although it preferably tapers slightly toward its ends to near the connections with the journal boxes where it flares slight- 1y, as illustrated particularly in Figures 2 and 4. The lower beads or ribs 9 ot the flanges 8 merge with the bolster columns 4: at the junctions of said columns with the compression member, and, as the inne flanges ofsaid columns are bent outwardly and form a lower web or wall of said compression member, said heading 9 may be considered as changing at the bolster columns into a lower web of said compression member thereby forming box sections for portions of the length thereof.

It will be apparent that the compression member, in changing "from a channel to an it or T section, passes through-a stage in which it is first a box section and then a smaller box section with the upper web thereof extended beyond the side walls, that is, it has two webs, an integral upper flange and a lower wall joining the webs. il here the webs 8 unite, the lower wall formed by the merging of the beads 9 is replaced by flange 1% which is curved downwardly and inwardly to form or merge with the u per flange oi the diagonal end portions or the.

in Figures 3 and G, the upper web 15 of which, however, extends outwardly beyond the side webs 16, as shown particularly in Figure 3, so to form an adequate support for the spring pla not shown, and the sugported springs. the lower edges oi the webs 16 are preferably joined by a transweb 17 preferably paralleling the upper web In addition. the upright side webs ill, the tension mem er is p" erably reinforced by an iutermeiate, preferably it web ill which two and securely rigidities the upper and lower webs there- As additional. ed'or r the side we s h respect to J extending subportions o are pre said webs slantially the lid

tioning the spring plank, not shown.

The main ortions of the tension member formed byt e webs 15, 16, 17 and '18, as

heretofbre described, are preferably bent' upwardly beneath the bolster columns 4 and continued for portions of the distance between said columns and the journal boxes 5 except that the upper web is preferably decreased in width, as indicated most clearly edges, as indicated at 25.

of the vertical web 1826.

in Figures 2 and 6, as well as the other webs 16, 17 and 18. The bolster columns 4, 1n

the embodiment illustrated, are shown substantially T sha e in cross section with inner transverse an es 23 and longitudinal flanges 24, preferab y beaded at their outer The flanges 24 are widened at the lower ends thereof and merged with the upper surface of the diagonally extending portions of the web 15 where.

they are continued therealong as upwardly extending reinforcing flanges or webs 26, the beading 25 being likewise continued and extended as upper flanges or heading 27 along the upper edge of the tension member where, at their outer ends, they-merge with the downwardly extending beading 14 on the compression member at the outer corners of the substantially triangular openings 28.

' Intermediate the bolster columns 4 and the journal boxes 5, the side webs 16 are discontinued, as illustrated in Figure 1, thereby transforming the main portion of the tension member from box to I shape in cross section, las illustrated most clearly in Figures 6 and .8. On account of the reinforcing web 26 and upper flange 27 thereof, the com lete section, however, becomes or star s ape and, as illustrated in Figure 8, has upper and lower flanges at the corresponding edges The distance from the center line of the side frame, at which the side webs 16 are discontinued, may e in accordance with the particular design of frame, as desired. In the particular embodiment contemplated, however, it is intended that these webs be continued to .approximately 16 inches from the center line of the frame and this distance preferably corresponds with the distance at which the compression member starts to change from box to I or T shape in cross section. In the embodiment illustrated, the web 15 is continued straight from the lower corners of the bolster opening to points adjacent the journal boxes where it is bent upwardly at an angle and joins with said journal boxes adjacent the roofs thereof. The lower web 17 is likewise extended but converges slightly toward the web 15 and, at a oint corre sponding' approximately to t e upward bending of said web 15, the web 17, which this point and, on account of the coincidence of the connection of the web 18 with the journal boxes and the brass lugs 29 thereof, coring at these points is facilitated.

The upper ends of the bolster guide colat this point is a flange because of the omisumns 4 connect with the lower edges of the v compression member 2, the inner flanges 23 of said bolster column preferably being bent outwardly and extended as a lower floor or web 31 of the compression member, as illustrated particularly in Figures 1 and 7, the

inwardly extending heads 9 of the compression member being merged with said floor 31. The webs or outwardly extending flanges 24 are preferably flared upwardly, as indicated in Figure 1, and merge with the lower web 31 of the compression member together with their heads or ribs 25.

Triangular reinforcing webs 32 are preferably provided between the roofs 11 of the journal boxes and the web 13 of the compression member, as illustrated most clearly in Figures 1, 2 and 4. Brake hanger brackets 38 are preferably formed extending inwardly from the inner depending flange 8 of the compression member 1, as shown most clearly in Figure 3. a

From the foregoing disclosure, it will be apparent that I have devised an improved side frame in which the sections of the various members are varied in shape and strength to economically take the stresses which they are called upon to bear in service, whereby the weight ofthe frame may be reduced without deleteriously reducing the strength thereof. A frame of the foregoing design can be constructed to meet the requirements of the American Railway Association.
