SIDE FRAME.

Application filed May 5, 1925. seria m, 2s,o71.'

Be it knownthat BYERS W. Khan, a

citizen of the UnitedStates, residing at Bale timore, in theState of Maryland, have in-.

vented certain new and useful Improvements in Side Frames; and I- do hereby declare-the following to be a full, clear, and exact description of the invention, such as will enpertains to make and use thesame.

This invention relates to side frames for railway car trucks and more particularly to the construction of those portions of a cast side frame with integral cent the ends of the frame.

The principal object of my invention,-'genorally considered, is the reinforcement of the union between integral journal boxes at the ends of a cast side frame for railway car trucks.

I An object ofmy'invention is the strengthening of the juncture between journal boxes formed at the ends of side frames for railway car trucks by carrying flanges on up above the top ofeach box and forming said flanges in line with the general direction of Another object of my invention is the strengthening of the-connection between in tegral journal boxes formed at the ends. of side frames for railway car trucks with said side frames and particularly in connection with cast frames'in which the compression and tension members are formed generally U-shape in cross-section and in which each membercomprlses v a web and *flangesat opposite sides of said web, r bs being provided in line with the web of the tension member,

extending from below the-top of each journal box to above the top thereof and slightly clearing the upper inner corner of each j ournal box whereby the union between each journal box and the frame is strengthened.

Another object of my invention is the provision of reinforcing ribs on the sides-of side frames for railway car trucks, said ribs.

being located adjacent a journal box and'extending across the outer faces of the side walls of the box portion of the frame above the journal box from the-tension member below the top of the journal box and preferably being swelled or increased in depth at :aproximately the corner of the respective journal box. Other objects and advantages of the injournal boxes adjatheside frame taken on the line 3- 3 of Figure 1 and looking in the direction of the arrow.

Referring tolthe drawings in' detail, sim- .ilar reference characters designating like.

parts in the various views,I have shown one end of a side frame 1 forrailway car trucks, Y

the remainder of said frame, not involving features of my present invention, not being 5 illustrated. Y

' Such a frame may comprise a compression member 2 and tension, member 3,the ends of said compression and, tensionv members being integrally united at 4, as is usual in side frames and referably formed witha journal box. 5 ad acent each union of compression andtension members- I The frame, as will be understood, is symmetrical on either side and may be formed as is usual, with bolster column guides or strut portionsspacing intermediate portions 4 V of the compression and tension, members. Such features, however, are not part of my invention'and as they are well: known. to,

stantially the full 'len h of the side frame I and at each end-of sai aside-frame is a journal :box 5. Said compression and tension members are each formed generally U-shape in cross-section with a main web portion '6 and flanged portions 7 on'opposite sides of the web portion, said flanged portions, in the embodiment shown, extending inwardly or toward each other. The outer edges of the flanged portions 7 may-bethickened or provided with a rib or head portion 8 extending therealong. It'will be apparent that in the present embodiment, the tension member is formed with a bottom weband upstand- I ing flanges at opposite sides of said web.

The outer portions of the web 6 of the compression member 2 are preferably sloped downwardly and outwardly and curvedto connect with the outer wallof each journal box at 9. In other words, the outer portion of the web of thecompression member is curved at its outer ends from an approximately horizontal to an approximately'verposition and joining 1t with the rooforups .per well 12 of the journal box, as" illustrated. The central portion o'f the web at this point tical position where it merges with the outer -wall of a journal box at 9. However, the construction may be lightened, if desired,

by cutting away a portion of the web 6 of the compression member adjacent. the connection with the journal box, as illustrated particularly in Figure2 adjacent the reference character 9. f

The corresponding flanged portions 7 of the compression and tension members 2 and 3 merge into each other at 10 to form a boxlike portion, as illustrated, over each journal box. The union between theweb 6 of the tension member 3 andthe journal box 5 is preferably a made by lcurving said web slightly at 11 to approximately horizontal connruction.

Approximately I webs 13 may be provided between the under may be cut away, desired, to lighten the portion of the web6 of the "teiisionimember and theinner wall l iof each j ournal box, .as is usual. The connection between each 'ournal box and the correspondin end 0 the side frame is reinforced byanges or rib portions 15 in line with the general plane.

' of the web --6 of the tension member and extending along theflanged portions theredf outwardly and upwardly beyond the top of the journal'box. "These flanges or ribs 15, as illustrated, preferably clear the inner cornerof each journal'box and are carried up wardly in a diagonal line across the outer faces of the side walls of the box portion of the frame above the journal box. These ribs or flanges 15may be formed on the outside or inside ofthe side frame or on both sides thereof, as illustrated most clearly in thereof,'I do not wish to be restricted to this particular construction because their width Figure 2. As there shown, the depth tof' each rib 15 is greatest adjacentxthe up er inner corner of the journal box and tapers or decreases therefrom both ways; to merge with the side walls of the frame. Although these flanges 15 are shown preferably swelled or increased at their intermediate or central portions by increasing the depth maybe increased as well'as their depth/or may be increased while their depth remains substantially constant, merely tapering slightly at the extreme ends.

- By virtue of the aforedescribedconstruction, it will be apparent that the union be-; tween each journal box and the correspond" triangular reinforcing,

ing end of the side frame is greatly strengthened and rigidified by the reinforcingflanges or ribs 15 extending at the critical portion of the connection at each end of the frame,
