Blomberg, om cago, Ill., assignors to Pullman-Standard Car Manufacturing Company, Chicago, Ill., a, cor poration of Delaware Application March 26, 1934, Serial No. 717,416 5 Claims. (Cl. 105-—4) This invention relates to cars of the type some times called articulated cars, and which com prise two or more sections having separate car bodies with adjacent ends articulated to and car ried by a common truck. And the principal ob jects of the invention are to provide great strength and security with free jointed or artic ular movement of the range required for railway service and to simplify the end sill and center 10 plate structures. Further objects and advantages will appear as the disclosure proceeds and the description is read in connection with the accompanying drawing in 15 which - Fig. 1 is a perspective view with the several parts slightly displaced and one end sill broken away to better show the general forms and rela tions of parts; Fig. 2 is a more complete perspective view of ' 20 the end sill broken away in Fig. 1; are ‘separated by antifriction or self-lubricating material 32, preferably of that type comprising porous metal charged with lubricant, and thereby providing self-lubricating bearings. The ?ange 29 of the center plate I‘! merges into side faces 33 (Fig. l) of considerable vertical width, and they all join what may be called the i) body portion of the center plate bracket [6, which has an upper face machined in steps 34 and 35. The lower step 34 has a transverse key groove 36 10 and the upper step has a stout dowel 31. The end sill l2 has, on its lower side, a ma chined face in steps 38 and 39, corresponding to the steps 34 and 35. The step 38 has a key groove 4!! opposite to the key groove 36, and receiving 15 with it a key 4!. The end sill also has a Vertical pocket or bore 42 opening through the step 39, and receiving the dowel 31. The body center plate bracket 2| has a ma chined upper face 43 and‘ a stout dowel 44 which cooperate with a machined face 45 and a pocket Fig. 3 is a longitudinal, vertical section along - or bore 46 of the end sill II, all as best shown in the center line of the car.v However, the speci?c form shown and described is intended for illustration only. 25 Swing motion trucks are generally preferred for articulated cars (Car Builders’ Cyclopedia, 1931, pp.g83, 569, 580) but that is a matter of selection from various types (Ibid., section 10, pp. 763 to 791). 30 The common truck is here represented by a bolster I0 and the car bodies by end sills H and I2. The bolster l0 carries a truck center bearing a plate [3, having-a pintle l4 surrounded by a con cave bearing surface I51. 35 The end sill I2 is equipped with a body center Fig. 3. A key 4'! corresponding to the key 41 traverses the joint between the faces 43 and 45. The respective end sills and body center plate brackets are made fast by bolts 48. It will be ob served, however, that the form and arrangement of the several parts relieves the bolts of .practically all duty except that of mere fastenings. The holes 42 and 4B for the dowels are formed in corresponding heads 49 and 50 on the respec tive end sills, which are ordinarily separated, as best shown in Fig. 3, by about three-eighths of anv inch in this selected embodiment. The bearing surfaces of the truck and body 35 plate bracket, generally indicated at 16 (Fig. 1) center plates are substantially spherical in form, which bears the body center plate I'I (Fig. 3), ‘ and will, therefore, allow the truck and the re having an opening [8 to receive the pintle l4, and presenting a convex bearing surface l9towards 40 the truck center bearing surface i5 and a concave bearing surface 20 upwardly. The end sill I I is equipped with a similar body center plate bracket, generally indicated at 2|, (Fig. 1) which bears a center plate 22 (Fig. 3) 45 having a bearing portion 23 and an opening 24 for the pintle l4 and presenting a convex bear ing surface 25 to the surface 20 of the body center plate ll. , The body center plate I1 has a downwardly di rected ?ange 26 forming a sort of protecting skirt for the truck center plate, and an upwardly di rected ?ange 29, which has a cylindrical inner surface 30, receiving a corresponding portion 3| of the body center plate 22. 55 The actual bearing surfaces of the center plates spective car bodies to have jointed or swinging movements relative to each other in all directions as the car passes over curved pieces of track hav 40 ing the outer side higher than the inner side, or as it passes over curves in vertical planes relative to the surface of the earth. There are no side bearings between the end sills and the ‘bolster i3. Instead. the end sills have arms 5| and 52 pivoted to links 53 which, in turn, are pivotally and resiliently connected to the end portions 54 of the bolster III by some means speci?cally unimportant here. By slightly'modifying the inner center plate bracket 2|, the end sill casting ll may be made identical with the end sill casting [2. Such a modi?cation would merely entail the provision of a step similar to the one indicated at 39 on the outer center plate bracket l6 and increasing the 55 2 2,135,523 height of the bracket so that the dowel 44 will properly engage the opening 46 in the head, 49. Preferably the pintle I4 is hollow so that bearing face downwardly and a concave bearing face upwardly, said center plate having a ?ange center pin may be used if desired. of said concave bearing face and a ?ange extend ing vertically downwardly about said convex - We claim-— 1.
