To all whom t may concern.:

Be it known that we, RANsoM C. l/Vmenr and FRANK E. STEBBINs, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and Washington, District of Columbia, respectively, have invented certain new and useful Improvements in Car- Trucks, of which the following is a specification.

Our invention relates to car trucks, and especially to the frames thereof and also to the combination of the frame with the j ournal boxes and springs.

Our objects are the production of a frame which can easily and cheaply be manufactured without the use of special appliances and can be repaired with equal facility, which shall be of ample strength at the upper end portions thereof where the weight is transmitted to the springs, which shall have the jaws or legs of the pedestals open at the bottom, and which in the preferred form shall allow the removal of an axle, a pair of wheels and two journal boxes by jacking up the end of the frame a short distance.

A further object is the provision of a combined wearing shoe and outer removable pedestal leg. And the final object is to form the main portions of the sides of flanged beams preferably rolled and to so fashion the ends thereof that very little labor will be involved in adapting them for the reception of cast metal pedestals.

Vith these ends in view, our invention consists in certain novelties of construction and combinations of parts hereinafter set forth and specified in the claims;

The accompanying drawings illustrate three examples of the physical embodiment of our invention' constructed according to the best modes we have so far devised for the practical application of theprinciples.

Figure 1 is a side view of a car truck in elevation with the cast metal'portion of the pedestal at the left hand in vertical section. Fig. 2 is a o-ne-half top plan view of Fig. 1, except that the cast metal pedestal is removed at the left hand end of the side piece; the other half of the frame being of identical construction is not shown. Fig. 3 is a view in elevation of the right hand end of the frame illustrated in Figs.

1 and 2. Fig. 4 is an enlarged section on line x-m of Fig. l. Fig. 5 is a top plan view of the cast metalpedestal. Figs. 6, 7 and 8 illustrate another species of frame construction, Fig. 6 being a side view with one cast metal pedestal removed, Fig. 7 a half top plan view of Fig. 6, and Fig. 8 an end view in elevation of the pedestal. Figs. 9, 10 and 11 show a third species, similar to the second species, but wherein the main portions of the sides are of rolled channel beams.

Referring to all the species, the numeral 1 designates the transoms which unite the parallel sides pieces adjacent their centers, said transoms 1n this instance being of channel beams spaced apart; 2, tie pieces which unite the transoms adjacent their centers; 3, I

top plates riveted to the flanges of the transoms at their centers; 4, the rolled flanged beams which constitute the side pieces, Sheet-s l and 2 showing them as I beams and Sheet 3 as channel beams; 5, top gusset plates, and 6 bottom gusset plates which are riveted to the flanges of the side pieces and the transoms; 7, connection angles which are riveted to the webs of the side pieces and thewebs of the transoms; 8, the lower straight and unbent end portions of the side pieces cut off square through the web and flanges or flange, said end portions abutting the journal boxes or inner bearing flanges of the pedestals; 9, the upper upwardly bent end portions of the side pieces shown extending over the tops of the journal boxes in each of the three species, though in some cases, when so4 desired, they may end on top of the boxes; 10, the wheels and axles; l1, the journals; 12, t-he journal boxes with their opposite vertical sides recessed or provided with flanges, in a manner well known; 18, helical springs upon the tops ofthe journal boxes; 14, the inner bearing flange of the cast metal pedestal; 15, the seat or pocket for the upper end or ends of the spring or springs; 16, the web portion of the pedestal at right angles to the inner bearing flange; 17, the vertical web portion which extends over the spring seat or pocket, both of said web portions being secured to the upper and lower web portions of the end of a side piece by rivets passed through the webs of each, as shown; 18, a seat in the pedestal for the reception of the lower flange of the or single flange in Sheet 3, as shown; 22,

clear that we have produced truck frames nwhich fulfil the conditions set forth'as the `1o pedestal jaw perforated to receive a tie bolt; 20, a flange engaging the lower flange of the side piece; 2l, rivets which are passed through said flangesthe inner flange of the I beam in Sheets 1 and 2, and the outer spacing piece; and 23 is a t-ie bolt.l

The cast metal pedestal shown on Sheet 1 has a composite outer legor jaw comprising an integral portion 24 downwardly eX'-" tended from theouter edge of the pedestal head or spring seat or pocket to a position preferably adjacent or below the center of the journal boX, or, in other words, this portion 24` hooks over the journal box, a longitudinal recess or slot 25 being formed in Y the downwardly .projecting portion 24 and said slot is preferably V-shaped and deeper at the bottom than at the top part of said projection, as shown, though it may be of any other suitable shape; and the combined removable leg and wearing shoe 26 having the `flange 27, web 28 at right angles to the flange, and the perforated lower end portion fory the tie bolt. This wearingshoe and leg 26 maybe of'wrought metal and forged to shape. The web 28- of the leg ts within the recess or slot in the p art 24, and the said leg and part 24 are united by boltsv29 passed through both Velements as lshown. f When the nuts 30 are tightened,

theremovable leg willbe held fixed by frictional contact relative to the projecting port-ion 24 so it cannot move in any direction.` The flange 27 is located insidethe projecting portion 24 andis in frictional contact Y with the journal box', andthe upper portion of web 28`is tapered so it can easily be inserted and'removed from the tapered` slot or recess 25. When .a pair of wheels is to be removed the tie bolt and bolts 29 are withdrawn, the leg 26 lowered from its seat,

. and the frame jacked up until the ends of the projections 24 are above the tops of the journal boxes. The'cast-met-al pedestals shown on Sheets 2 and 3 are of substantially identical construction, the outer leg or jaw 31 in each species being integral with thel spring seat or pocket or head of the pedestal and comprised of apbearing flange 32, a webz33 and an enlargement 34, the lower end of the leg also being perforated to receive the tie bolt.'

In fashioning the rolled flanged beam for a side piece the lower flange and web may be cut on the line L -Z) (see Fig. 6), the upper flange andweb on line c-d, the web cut longitudinally on the line ej-b-cl, a portion of the web above line d-b removed, and the remainingV portion thereof with the upper flange then bent upwardly to the position shown in Fig. 6, wherev the top flange of the lupper projecting end, portion is in a plane substantially parallel with but aboveside piece; 19, the-lower portion of thehinnery the plane ofthe top flange Aof the beam adjacent the transom ends. After both ends have'been similarly fashioned, the holes for objects or purposes ofv our invention. The

ends of the side pieces can easily and cheaply be fashioned for the reception of the cast metal pedestalsg`when the pedestals which preferably have integralspring seats or pockets have'been riveted in position, there will be ample strength on the line t where the weight is transmitted to the top end ofthe helical spring or springs 13; and the removable portion of the outer pedestal leg or jaw permits the rolling ,out of a pair of wheels by jacking up the frame a `short distance.l Moreover, should the outer removable leg become eX- cessively worn, another can be substituted.

Minor changes and modifications may be introduced in the practical application of our improvements, as, ,for instance, the lower portion of the inner pedestal jaw may be made separate, the shape of the spring seat or pocket be altered, and the upper end of the removable part of the outer jaw in the lirst species interlock with the downwardly projecting portion in a different manner. Such and other modications we shall not regard as substantial departures. Y
