. ALBERT O. BUCKIUS, OF CLEVELAND, OHIO, ASSIGNOR v'I O NATIONAL MALLEABLEIAND- l STEEL CASTINGS COMPANY, OF CLEVELAND, OHIO, .Av CORPORATION OHIO SIDE vFRAME Application led Iebruary, 1931. Seria1No'5'13,062.

This invention relates to improvementsin side framesfor railway car trucks Vandvhas particular reference to the provision of suitable means to be added to a .frame commonly known as the Andrews type for the purpose',

of readily adapting it for the reception of a roller bearing journal box.`

The Andrews type offrameisa cast struc,.-v

ture having integral tension and compression members and the journal boxes are adapted to be bolted to extensions at the ends of the frame. Further .support` for each of the boxes is provided by a. tie bar or plate which` is riveted or otherwise secured to the-frame casting and connected to boxes.

It has been an object of the presentl inven tion to develop an auxiliary frameV lwhich may be readily applied to each end'of an Andrews frame for the purpose ofadapting" it for the reception o f a roller bearingjour-,

`sideV nal box having provisions, includin lugs, for mounting it flexibly 'in the rame. The auxiliary frame contemplated by the vpresent invention is suchv thatV aV pair of downwardly extending guide columns or pedestals is provided, these being formed with channelled guideways adapted to per` mit angling of the roller bearing journal box relative to the frame. Attachment, of the box to the frame may be,l effected solely byV 1the employmentV of pins adapted to be insert-v ed through openings in thepedestals. These, pins, furthermore are necessitated simplyl for the purpose of retaining the box in the frameV when the truck is 'lifted from the tracks. Inthe normal use of the structure no separate means ofv holding the box in proper relation to the frame is required to function and the pins mentioned will not'interfere with the desired freedom of action. j

A particular feature of the auxiliary frame is the provision of strengthening means at the corners where the downwardly extending columns or pedestals are joined to the horizontal, connecting member of the frame."

This reinforcement at thecorners enables the use of simple attaching means for the' journal box, as mentioned, and permits the elimination of atie bar or similar reinforcing.`

Referring now to theV 'drawings,`there' is', illustrated a portion` at one end of aside frameV 10 of theAndrewstype havingthe tension and compression members, including the top arch bar 11 and bottom arch bar 12,

cast integral. This frame may in generalbe similar to that illustrated in the patentto Lamont, No.' 1,009,979, `granted November 28, V

1911. "A flat under-surface V13 is provided on the frame, this surface being normally adapted to cooperate with the flat upper surface ofv an arch bar type of plain bearing journal box.

Suitable boltV holes 14 areprovided through bosses'on the lower flange of the frame for the reception of the attaching b olts-` normally employed in securing frame. s

` According to the present invention an aux:v iliary frame 15 is provided having a pair of downwardly extending columns or

pedestal portions

16 and 17 and a horizontal, connecting portion18. The. latter is formed withl flat, upper surface 19 adapted to cooperate with the surface 13 of the main frame. O'pen-y ings 2O 'are formedthrough the portion'lS in an arch bar box tothe each flaring outwardlyA from tl e lower ends of the guides toward the upper. ends ofythe.

latter. T he flanges 22 have an upwardly extending portion Ql which, as best shown-in'y Fig. l, cooperates snugly with the end of the main frame and provides a smoothly curved upper surface as an extension of the upper edge of Vthetension member 1l. The upper edge 25'. of the flange portions 23 is inclined in the direction of the compression member 12 and preferably at a slightly greater angle to the horizontalsoas to provide a small frame.

ferablythe clearance as shown. nwardly projecting flanges 26 are provided at each side of each of the pedestals; these flanges give additional strength and rigidity to the auxiliary To increase thereinforcement afforded by the inwardly extending flanges, thelatter are enlarged at their upper ends 27 Where they are joinedto the horizontal portion 18. This' enlargement is substantially to the maximum-extent permitted'by the contourof the-.roller bearing journal box whichl is to be received between the pedestals, as will more clearly appear hereinafter. A

Within the auxiliary frame there is adapted to be mounted a roller bearing journal box 28 having side lugs 29 adapted to lit ntor the channels provided between the side flanges ofthe

pedestals

16 and 17.. The relation between the side lugs andthe pedestals is presame as in my pendingapplication Ser. No. 259,023, filed March 5, 1928. The faces 30 of the pedestals are preferably straight in a vertical ydirection and arcurate or curved in a direction transvers of the franie,as best shown in Fig. Correspond ingly curved surfaces 31 are Vprovided on the ends of the side lugs, these surfaces having a' slight normal clearance from the surfaces 30 so as to permit lateral angling of the box within the frame, and preferably also a slight bodily movement of the box. between the pedestals. Suhicient clearance ispro# vided between the sides of the lugs 29 and the` inner surfaces of the flanges 26 to permit the .desired angling.

At its top the box may suitably be provided Withva recess surrounded by la. rib 32 and adapted to snuglyvreceive a bearing block or plate 33 of good wear resistingmaterial.v

' "The upper surface 34 of this plate is preferably straight in a direction transverse to the' axis of the journal but is arcuate or curved 1n a direction Ylonritudinal `of the journaltoY readily permit verticalangling. This upper surface 34.- of the plate is adapted to support the under surface 35 of the portion 18 of the auxiliary frame, which is pref erably flat. On either side of the portion 18 of the auxiliary frame upwardly extend ing projections 36 may be provided on the box, these being adapted to cooperate with the side surfaces 37 of the portion 18. The

vsurfaces 36 and 37 are preferably curved transversely of the. box, the curvature of the surface 36 beinggreater, i..e..of shorter radius than the surface 37 so as to provide for easy lateral angling between the box and frame. A normal clearance of suitable extent is also provided between'oneor the other of the sets of cooperating

surfaces

36 and 37 to allow for vertical angling ofthe box. These surfaces, furthermore, may advantageously be angled slightly to the vertical, as shown, to more effectively resist the angling and thrust forces between the box and frame.

ln order to retain the ournal box between the `pedestals when the'car truck is lifted from the'traclr, a pair ofpins 38 may be provided and these may be passed` through ysuitable openings 39 formed in the pedestals at a point slightly below the normal position of (the, lower edge of the side lugs 29 of the box. A

cotter pin at oneend and an enlarged head at the opposite. end may serve to ret-ain each pin 38 in position in the pedestals. As shown in Fig. l, sutlicient clearance is provided between the side lugsand the pins 38 to permit the desired angling movements of the box. Adequate clearance to. permit angling and providefor. easy assembly is also allowed betweenv .the flanges 26, including the enlarged portions 27 thereof, and the outer contour of the box.

W ithin the ournal box anyA suitable roller bearingconstruction may be provided. For example a plurality of rollers 40, carried by suitable cages 41, may cooperate directly with an integral,hardenedraceway provided on theinner surface of the journal box and these rollers also bear upon a hardened race formed by the outer surface of a sleeve carried by the journal 42. Any appropriate means may be provided for properly` lubricatingthe bearings and for accepting the end thrusts between the boxv and journal.

lVhile oneillustrative form of the invention has been.v disclosed in considerable detail, it is to be understood that various changes in. they construction and arrangement of the-parts may be made without departing from the general. spirit and scope of the invention as defined by the appended claims.
