A further object of our invention is the provi sion of a railway truck in which the wheels are quickly changed by lifting the frames to pull the pedestal jaws olf the boxes, or by removing retain 2Ul ingbolts connecting the bolster and frames and lifting the bolster off said frames. 1 A still further object of our invention is the provision of a self-squaring and self-centering railway truck adapted to resiliently support an 30 associated railway vehicle body by springs be tween the side bearings and. bolster, resilient cushions merely being provided between the bol ster bearing castings and the associated side frames, said truck being preferably provided with y35 conical side bearing rollers and having no spring plank or plates. - Other objects and advantages of the inven tion relating to the particular arrangement and construction of the various parts will become 40 apparent as the description proceeds. Referring to the drawings illustrating our in vention, the 1 scope whereof is defined by the appended claims:- . ~ .

Figure 13 isa fragmentary sectional view on the line I3-‘-I3 of Figure 12, looking in the direc tion of the arrows. Figure 14 is a perspective view of the brake hanger bearing piece detached from the asso 25 ciated parts. _Referring to the drawings in detail, and ñrst considering the embodiment of our invention il 30 lustrated in Figures 1 to 9, inclusive, there is shown a truck l comprising two pairs of wheels 2 and connecting axles 3, only one pair being illustrated, as the truck is symmetrical. Around each journal 4 of theaxles 3 is a journal box 5 35 with an associated brass or bearing 6, each jour nal box preferably having a. pocket 1 in the roof thereof receiving a hardened steel insert 8 hav ing a crowned or cylindrically convex upper sur face 9 normally engaged by the corresponding 40 lower surface’lll of a corresponding block il in the corresponding jaw l2 of an associated side frame i3. It is not necessary to describe the mounting of the side frames -i 3 on the journal boxes 5, as such mounting is illustrated and pref-' 45 erably corresponds with that described and claimed in the Barrows Patent No. 1,779,526, of October 28, 1930, whereby equalizing of the jour nal box in the vertical axial planes of the jour nals is permitted. ‘ The rocking engagement between the bearing blocks 8 and il of the journal boxes 5 and frames I3 not only permits equalization of the boxes, but also allows for swinging of the frames on said boxes, whereby the lower or tension members .M 50 2 2,066,602 of said frames are adapted to move laterally when such swinging takes place. Each frame is desirably also provided with a compression mem ber I5 and bolster guide columns I6 spacing in termediate portions of said compression and ten sion members, leaving a window or bolster open ing I1 therebetween. - The associated bolster I 8 is desirably supported from the frames I3 by resting at each end, on a 10 bolster bearing -casting I9 which, in turn, rests on a resilient or rubber pad 20 supported on the tension member I4 beneath the window opening I1. Each casting I9 desirably has ñanges which straddle the tension member .I4 of the corre 15 sponding frame. The frames I3 of the present embodiment are preferably of the double truss type, such as shown in the Barrows Patent No. 1,652,808 of December 13, 1927, so the pads 20 and bearing blocks or adapter castings I9 are 20 formed to clear the reinforcing or double truss portions 2I of the frames. The upper surfaces. of the bearing castings I9 and the engaging surfaces of the holster I9 are formed so that rocking therebetween is permitted 25 without gouging. In the present embodiment, the upper surfaces of the castings I9 are formed brake hangers 40 at al1 times to hang in proper relation with respect to the associated wheels 2, the trunnions 31 permitting lateral angling of the hangers 40 to compensate for swinging of the frames I3, and the pins 39 permitting longi tudinal angling of said hangers, whereby pro vision is made for universal movement thereof. The trunnions 31 are desirably flattened at the sides, as indicated at 4I, to permit insertion in the bearings 36 through the channels 42 which 10 communicate with said bearings, said trunnions being, when in normal position, prevented from displacement from the bearings, as will be under stood, particular reference being had to Fig ure 6. 15 Referring now to theA embodiment of our in vention illustrated in Figures 10 to 14, inclusive, a construction is there disclosed which corre sponds generally with that of the preceding em bodiment, except that the brake hanger brackets 20 35rt are mounted on the bolster I8“, said brackets having housing portions 43 >normally receiving generally cylindrical bearing pieces 44 slotted, as indicated at 45, to receive the upper apertured ends 46 of the brake hangers 40“, said brake hangers being connected to the'bearing pieces 44 generally convex, each with a flattened central ~ by pins 39a. The slots 41 in the housing por portion, and the corresponding surfaces of the tion 43 -receiving the ends of the brake hangers bolster are formed generally concave with flat-l 4I!"L are desirably widened, as compared with the 30 tened central portions, the curvature, however, slots 45, so that the bearing piece in each housing $0 being on greater radii so that rocking or rolling 43 is movable longitudinally of the bolster. Such therebetween is permitted, the flat central por longitudinal movement relative to the bolster is tions serving to cause the bolster to tend to re main in central~ position so that the truck is self 35 centering. In order to limit lateral motion of the bolster upon swinging of the frames on the out side articulated journal boxes heretofore de scribed, a retaining member or bolt 22 desirably passes loosely through each end of the bolster 40 and through the guide columns I6 on either side of said bolster.~ It will, therefore, be seen that the bolster may move laterally, causing the asso ciated side frames, only one of which is illus trated, to act as swing links as they rock on the journal boxes. To provide for the adequate resilient mounting of the associated railway vehicle or car body bolster 23, the truck bolster I9, adjacent each end, desirably has an upwardly opening pocket 50 24 formed by downwardly offsetting a portion of the upper wall thereof, receiving a nest of springs provided by an extension 48 notched, as indi ~cated at 49, to engage a flange or lug 50 on the corresponding guide column I6“, so that even though the bolster I 8a moves laterally the bear ing piece 44 and the associated brake hanger ‘ stays ’the proper distance from the associated frame I3a so as to be properly disposed withl re spect to the associated wheel (not shown). A retainer 5I desirably serves to prevent loss or undesired removal of the pin 39‘. It will, there fore, be seen that although the features of the present embodiment not shown correspond with the previous embodiment whereby the side frames I3"l serve as swing links for yallowing lateral move ment of the bolster, such lateral movement does not interfere with the proper relation between the brake hangers 40* and the associated wheels (not shown). A In view of the foregoing, it will be seen that We have provided a truck in which the side frames 25. Supported on the upper ends of the springs 25 is a spring cap 26 on the upper surface of which, themselves function as swing links for allowing between upstanding flanges thereon, are mounted ’ lateral motion of the bolster. -To permit the nec 55 side bearing rollers 21, said rollers, in the pres essary freedom of motion, we have incorporated ent embodiment, being preferably ground cones and having toothed portions 28 at their ends en . gaging corresponding toothed portions 29 on the body side bearing 39 to maintain them‘in desired position. The surfaces 3I on the 'spring cap 29, and 32 on the side bearing 3l! are desirably con cave toward each other, so that the truck is made self-squaring by the raising of the body upon angling of the truck about the center plate 33, l65 the lower end of which interlocks in a. corre sponding pocket 34 in the top of. the bolster but does not normally serve to support the car body 23 from said bolster. , Theside frames ofthe present embodiment are 7.o preferably provided with brake hanger brackets 35 providing bearings 36 receiving trunnions 31 on brake hanger blocks 98 through which nor mally extend brake hanger pins 39 which, in turn, flexibly support brake hangers 4I). The 75 purpose of this flexible mounting is to enable the the outside articulated journal box’ already the subject of the Barrows Patent No. 1,779,526 of October 28, 1930, using conical roller side bear ings and truck springs between the side bearings and bolster instead of between the bolster and side frame. The brake hanger brackets are either mounted for universal movement with re spect to the swingable side frames or are mounted from the bolster with provision for relative lat eral movement therebetween, whereby the proper relationship of the brake hangers and the wheels is maintained. f ' Although preferred embodiments of ourßinven tion have been disclosed, it will be understood that modifications may be made within the spirit 70 and scope of the appended claims, and that V'the terms employed are used as those of description and not of limitation. .
