Be it .known that l, Gnonon G. FLo 'in-a citizen of] the United States, 1'0S1(l111 l at '(rraniti, in the county ofhLa-dison and State of Illinois, have invented certain new and useful improvementsin Track Side Frames is a s; eciiication. y

it has been proposedheretoforeto 'oast the journal boxes of a railway cartriick inwith the side framesgbnt owing to the xi'liii'iciilt in casting side .i'ramcs with such in t - boxes the iirna becon'ies co-nsi stead of indircctl to the side frame.

V In. Figs. 1 to 5 inclusive I have illustrated a simple and desirable embodiment of my At each end of the side frame is a horizontal forated at 36. v 35. is a bracket 37 integral with the side flat surface 32 extended downwardly from whichare a pair of transverse lugs or projections 33 and 34rectangular' in shape. The rearvertical edges ofthese lugs are substantially flush with the innef or back Wall of the side frame, while their outer edges are set in somewhat from the front surface of the side frame as is clearly indicated in Figs. 1 and 5. In order to brace this pair of lugs and securely maintain them in (position the lug 33 is connected-to the un er surface of the angle tension member '31 by a vertical web 35 at the rear-face of the frame, integral with the frame, and per- 111 alinement with this web cludes a box or casing 39, the lowerfront ortion of which is rounded while the rear ower portion is rectangular as issho'wn in Fig. 3. Thisbox has a top wall 40 arising from which is a curved transverse flange or plate 41 which projects beyond the side walls of the box and'partavay down them to form 0 (.positely-extended ears 42 which are prov1 ed with holes 43. Y

Extended longitudinally-ofthe .box just inside of its side walls there is provided a pair of slots 44and 45 which extend through the top wall 40 of the box and are-of dimensions substantially equal to the width and thickness of the projections 33 and 34. Also extended outwardly from the side walls of the box 'I provide the pair of ears 46 apertured at 47, these cars being parallel to the ears 42 and spaced away from the same a distance substantially equal to the thickness of web 35 or bracket 37. Between the cars 42 and- 46 the side walls of the journal box-or casing are vertically slotted at 48 to a depth substantially equaling the depth of web 35 and bracket 37.

Extending downwardly from. the inner surface of the top wall 40 of the journal box and near its outer end is the usual pair of atop fingers or lugs '49 cast integral with the When the journal box or casing and side frame are assembled, thetop wall 40 lies immediately below the horizontal plate portion 32 and the flange 41 .abiits against the inner face of the side frame as is clearly shown in Figs. 4 and 5. .Bolts' 50 passing through the ears 42 and 46 and the web 35 and bracket 37 bind the journal box to the side frame, and,-when the parts are thus assembled, lugs or prrp'ections 33 and 34 extend intoqthe interior of the box or casing and lie adjacent to or against the inner surfaces of itsside walls. As is usual, the car axle 51 projects into the journal box and is equipped with shoulders 52 and 53 as is customary. Resting upon the upper surface of the reduced portion of the axle is a bearing 54 of any suitable shape and dimensions, the bearing havin lateral shoulders 55 which project in front 0 the outer edges of lugs 33 and 34 and'cooperate there-with to prevent inward shifting of the bearing and axle. Above the bearing is placed the usual wedge 56, the

outer end of which is adapted to cooperatewith the stops or fingers 49 of the journalbox, it being understood that the inner ends of the bearing and wedge overlap whereby inward movement of the axle and bearing are prevented by-the lugs 33 and 34 while outward shifting-of the axle, bearin and wedge is prevented by the stops 49. fit

'As is obvione the inward movement of the axle in relaoutward movement relative to the other side frame, so that shifting of the axle in with a ertures to accommodate the fastening bo ts I supply the horizontal plate 32 with corresponding holes 36 and 38. The journal box or casin is like that shown in Fig. 2 ,except that t e ears' 42 and 46 are omitted and in the place of the latter I equip the box with horizontal ears 46 integral will be apparent from this description and illus- .tration that the shifting of the axle is trans- \tion to one side frame corresponds to the".

' In Figs. 11 to 15 inclusive I have shown a another modification of my invention and in this form' the compression member 57 as well as the tension. member 58 of the cast.

side frame are substantia ly I-shape in cross section. Near each end of the frame the lower flange 59 of the tension memberis off-set to provide the horizontal abutment 60, the flange then extending vertically to supply the upright-wall 61, then horizontal v to provide the plate portion 62, and

finally downwardly to supply another vertical wall 63 parallel with the strip 61.

This latter portion 63 is in reality a continusme ls etion of the top marginal flange 64; of thev eompression member or portion of the side frame.- Depending from the horizontal piste portion 62 and integral tnerewith are '31 of lugs 65 end 66 which eresim-er-il li'oin the strips (51 and S3 and eone1 to by the webs t)? and 68. in wall 63, assist in insinv'th :i-n externeleurvml flange or rib 69. onts l well (ill has a hole 70 there and above part 60 the web of the side from is entnvay to form zi' reeessthe purpose of which is ti'i'permit the insertion of bolt through the aperture 70 from the inner side of'wall 60.

The cooperation'between the parts of the truck so far as this invention is concerned has been explained above and it may be stated that in order to prevent cinders, dirt, and

other foreign substances from entering the journal boxes suitable packing may be used at the places where such substances-are likely to find entry. Such packing has not been illustrated on the drawing since its use would be obvious to those skilled in the art.

I have illustrated in detail the features of the various embodiments of my invention, but I desire to have it understood that my invention is not restricted to the details of construction shown and described, and that many changes may be made in the parts set forth without departing from the essence or heart of my invention.

I claim:

1. A car truck side frame having a part adapted to project into the interior'of an independent journal box or casing, substantially as described.

2. A'car truck side frame having a portion integral therewith adapted to project into j a bearing having an aperture through which a part of said side frame pro ects into the interior thereof, substantially as described. I
