strong and durable, with a novel pedestal tend'vto the front and rear sides of the tranma rnsn, or WALLA WALLA, wasnmeron W CAR-TRUCK.

To all whom it may concern? f Be it known that I, JO N-A. Busrnajciti-i zen of the United States, residing at lValla \Valla, in the county of lVallmlWalla and State of lVashington, have invented certain new and useful Improvements in Car Trucks, of which the following is a specification- This invention relates to car trucks, and its object is to provide a structure which. is

structure whereby adjustment of the wheels canbe readily made. V I

The invention. also has for its objectto provide a novel and improved construc tion and arrangement of equalizers, safety 7 hangers and other parts, as will be described in detail hereinafter.

In orderthat the invention maybe better understood, reference is had to the accom-- panying drawings, in which Figure 1 is a plan view of thetruck; Fig. 2 is a side elevation thereof; Fig. 3 is an endview, partly in section; Fig, 4 is a cross section on the line 4-4 of Fig 1, and Figs. 5 and 6 are details in perspective.

Referring specifically to the denotes'a transom which is a steel casting of suitable shape at its ends to properly conform to the side frames 11 of the truck, and extending outwardly from the latter to support the side bearings 12, with integral forwardly and rearwardly extending wings 13 forming gusset braces for the side frames and also supports for safety hangers 14. The wings will also support brake hangers, bolt-holes for the same being shown at 15. The transom is of sufficient'thickness at its ends so that it may be here recessed, at the bottom, as indicated at 16,-t form seats for the top spring saddles 17. The portions of the wings which support the safety hangers are cast thicker on top, as indicated at 18, to

providejseats for nuts 19, and on the under side the wings have nut seats 20 which ex-.

som to brace the wings.

The side frames 11 have pedestals at theirthereto. Each side frame has a top recess 23' to accommodate nuts 24", the recess being wideenough to permit application ofa wrench to the nuts,and deep enough to leave Specification of Letters Patent. I

ample clearance between the .car frame and the bolts 25 on which'said nuts are screwed.- These bolts fasten the sideframes-tothe flZlIlSOIH'BIlClS, the heads ofthe bolts' bei'ng r Patented Jan. 4:, 19.16.; Application filed May'lfi, 1915. Serial No. 28,371.; I 3 i T countersunk in thebottom of thelatter as a indicated at'26.

Each removable pedestal horn 22 has a tenon27 at the top which fits in a mortise 2S in th e'under, side of the frame 11,-and is here held rigidly in place by a wedge-Shaped 'key 29" driven through the tenon; and the mortised portionof the side frame, said parts having-register ng apertures to receive the key.- The key 1s secured by a nut truss rod 30 passingthrough the pedestal V v horn 21, the-latter'being apertured, as indicated at 31, to receive the truss rod. The length of the truss rod is such that it extends between the pedestalhorns 21, and also at each end beneath the journal boxes 32 across to the oppositeremovable pedestal horns 22. 2

Between each horn 21 and the oppositeremovable horn 22, below the journal box, is a pedestal cap 33 forproperly spacingthe horn 2 2, and said cap has a longitudinal bore to receive the truss rod. The truss rod and the pedestal caps firmly bind the horns together, with; the proper spacing therebetween, and also form, with the frame 11, a rigid truss. I

The equalizers 34 are cast in" one solid piece and have no bolt holes or other apertures so. that they retain their maximum strength. The webs of the equalizers have .top recesses 35 forming seats for the lower equalizers 34: and-the truss rods 30, thebottom portion of the hangers being shaped to produce'shoulders 38 to hold the equalizers and afford perfect safety from any fallingj member whichmight otherwise come in contact with the track bed, ties or rails and cause awreck. I v p The ends of the trussrods-30 carry nuts 39 which are screwed against the pedestal horns 22, and intermediate their; ends the rodsareseparated and connected by turne buckles lOhaving loolrnuts 41; at their ends he truss o also ha e fixed-n t or abuta, 7 ,1 6 29% The horn; is held at the bottom by a r i ments which seat in recesses 43 in the V outer faces of the pedestal horns 21. The inner opposite faces of the horns 21 and 22 have shoulders or si l en 'ageablc by the ends of the caps 33, and said caps have top recesses at their ends for ning seats for the lower ends of the pedetal shoes 4L6 which fit against the inner races of the pedestal horns. The ends of the side frames 11 have short dependingstubs 4-7 in which are the mortises which receive the tenons 27. The shoes 46 have top tongues at which are opposite the inner faces of the stubs, said faces being slightly inclined, as indicated at 49, for a purpose to be presently described.

To take out either set of wheels of the truck for any purpose, the pedestal horn corresponding to the set of wheels to be removed must be taken which is done in this manner: The nuts 39 are removed from the end of the truss rod 30 corresponding to the horn to be removed, and the key 29 which holds said horn the top is driven out. The turnbuckle -10 is then screwed up to withdraw the fixed nut 4-2 from the seat 43 in the horn 21 opposite the horn to be removed. The loose end of the truss rod is then screwed into the turnbuckle until its end from which the nuts 39 were removed, clears the horn whereupon the latter, with its shoe 4:6 is readily withdrawn. It will be noted. that the shoe 4-6 rests on the pedestal cap 33, and to be removed it must first be brought over the end of said cap. This has been provided for by the incline 49, which latter gives the shoe a little side play, said play being taken up by the straight face of the pedestal horn against which the shoe fits. The side play is suliicient to allow the shoe to be tilted to clear the end of the cap The pedestal cap is next slipped off the truss rod, and the truck frame is jacked up until the journal box is free, after which the wheels may be rolled out.

To completely r more the trussrod 30, the same operation hereinbefore described is carried out, and continued by unscrewing the turnbuckle l0 from the other end of the rod, removing the nuts 39 at said end and then passing the inner ends of the rod sec tions by each other and drawing them from the pedestal horns, the holes 31 in the pedestal horns 21 through which the rod passes. being large enough to permit a sufficient sidewise tilt at the turnbuckle ends for said ends to pass each other.

By the arrangement of the truss rods 30, the turnbuckles l0 and the removable pedestal horns 22, the latter are double locked and it is impossible for said horns to work loose and drop off, the'distance between the innor ends of the rod sections not being sufficient to allow both sections to enter the turnbuckle at the same time far enough for the outer end of either section to clear the horn, even though the nuts 39 should be off. The horn would still be held up by the truss rod and supported in vertical position by the tenon 27. Thus, the possibility of. loss f the pedestal horns is entirely overcome. The transom, side frames and equalizers, being each in one piece, are stronger and safer than built up of a number of parts held together by bolts, and as they are cast they are also cheaper. The pedestal structure also enables the truck wheels to be readily adjusted to keep the wheel flanges from wearing against the rails. This adjustment is readily made by the simple process of shimming. up and dressing off the proper pedestal shoe, thus making the wheels run true to the tread. Ordinarily, this cannot be done except at a great expense and with much trouble as the Work must be done on the pedestal horns which become badly worn, whereas in the present truck the work is done on the shoes, leaving the same always in a perfect condition.
