Itis an object of our invention‘ to provide an‘ I articulated construction between railway cars. It is theparticular object of the invention to 5 pprovidean articulation which permitsthe cars be ing separated withoutelevating the cars to remove the trunnions from the center plates or sockets. The object is to provide a two-part center plate, orsocket, vthat can be used as a single socket or (c1..1o5_.4,) ’ plate or socket or unlocked. The further ad- v vantage is secured of not disturbing the vestibule in‘ any manner so that it will travel with one of the cars,‘ and needs no special mechanism for that‘ purpose. Under the present method'it is necessary 5 . to completely dismantle the trunnions from one another and ‘from the socket platev or'center plate, and it is necessary to give special treatment to 'the vestibule", both in assembling and dis assembling." ‘It is necessary to use ‘heavy cranes,’ mi "as a single body having a plurality of sockets, and which can be split in two parts when de with special cradles, in order to pull the cars apart sired. When so split the two-part center plate is and supportthem when it is necessary to inspect still engaged with the respective trunnion of the thertrunnion joints, and lubricate. The present respective-car with which the half of the center invention eliminates these disadvantages. ' 1plate is associated. By our invention it is possi The present articulated cars do not ‘provide .for} ble to detach one car from the other without de mounting the trunnion from the particular socket universal movement of the trunnions and the sup port for the vestibule about a common center. I irirwhich it normally rests, or the particular half They do not provide broad bearing ‘surfaces for of the socket ‘in which it normally rests. A further important object is the provision end thrust. They do not provide for'closely' en: gaging interlocking faces without lost motion, or of a socket or center plate surface described about taking e'nd thrust. In the present case the end 20 the‘ center of the movement of concentric inter thrust istaken directly through the trunnions,‘ locking trunnions, while at the‘ same time per and the center platei's primarily used‘for its nor-' mitting ‘each trunnion a bearing face engaging mal function of support. ‘The present invention.‘ wtwith the respective half of the bifurcated socket further permits of free movementof' the’ trune 2r} in" which it rests.

It is‘ also an object to provide for the support of this vestibule so that it will rotate with the bolster upon which the center plate or socket is mounted, and it will be permitted to work with in ‘a limited'degree about the center of movement of'the trunnions. . . It is a further object to provide for the sup porting of the vestibule or the vestibule platform, 40.;or'both, in overlapping relationship with respect to‘the ends of the car bodies in such a position that the ?oor of the vestibule is maintained in substantial alignment with the ?oors of the cars. v"It is a’ de?nite object to support the vestibule 45 _-;?oor either with orv without the vestibule casing within one of the trunnions so that when the trunnions are separated, upon the separation of the bifurcated center plate, the vestibule will travel with one of the cars and will be supported in the trunnion of the car with which it travels.‘ This invention obviates the present di?iculty of the necessity‘ for complete dismantling by eleva tion of both cars at their articulated ends in'order " to separate them.

It is preferable to remove the left-hand which constitute the socket or center plate bear ing. The inner surface of; these halves form a body and trunnion because that leaves the right 10 hand body,.socket plate and trunnion on the semi-spherical surface described about the cen ter 28. The upper margin of this‘semi-spherlcal bolster, and the trunnion 22 then supports the surface is provided with an over-hanging ?ange vestibule platform 38 without disturbing that 2| to prevent the withdrawal vertically of the platform. Likewise,‘ the cars can be assembled by reversing the steps just indicated. By provid trunnions, hereinafter described. . 15 The right-hand trunnion consists of a portion ing the overlapping halves of the casing around 15 of a sphere, designated 22, having a surface 23 the abutting halves of the socket plate the planes described about the center 20 and engaging with of division of the'casing and socket plate are at right‘ angles strength It will and be understood security inthat the. articulation. we desire‘ to‘ com-1 surfaces described about the center 20 so that they engage with and fit the halves l8 and IQ of the center plate. Both of these trunnions are prehend within our invention such modi?cations ' provided, with shoulders 26 and 21, which engage with the overhanging flange 2| to prevent with 25 drawal vertically of the trunnions when in op eration. A space is left at 28 between the faces 29 and‘ 38 of these trunnions to accommodate a stud 3|, which is located at the bottom of the center plate. The purpose of the stud 3i isto 30 hold the trunnions from sliding out of the center bearing plate, when the car bodies are separated, 35 to one This ‘provides ' ' II a similar surface 24‘ of the trunnion 25, shown in section. Both of these trunnions have their outer another. as come within‘the scope of the claims'and the?3 invention. 1 Having thus fully described our invention, what ' we claim as new and desire to secure by Letters 25) l Patent, is: ' ' ' I 1. In an articulated car construction-the com_'-' bination of a divided'center' plate, trunnions‘ mounted in said center plateto permit‘ hori-i zontal and vertical movement of the car bodies, said trunnions being so'arranged as to‘ be sup-‘:1 and when, therefore, the trunnions are separated ‘ ported by said center plate as ito transmit thrusts from the car bodies through said trunnions; and-'5. from each other. This occurs'when one car is means for detachably attaching at least ‘a part backed off from the other, or when both cars are moved in a direction away from‘ each other. of said center plate to a truck bolster support That is' the time that the stud 3| functions to keep the part of the trunnion on the right, and ‘ the part of the trunnion on the left, from coming out of the halves I8 and I9, respectively, of the 40 center bearing plate. . ing said trunnions and car bodies,~whereby the‘. opening resulting, fromdetaching a ‘part of the . center plate permits the disengagement of the. trunnions from one another without vertical; movement thereof. ‘ The right-hand trunnion 22 is provided with an open-endedpassageway 32, the bottom of which is semi-spherical, as at 33, for receiving the ball 34. This ball and its receiving surface 45 33 have their surfaces described about the same center 28. Mounted upon this ball is the sup porting pillar 35 for the floor 36 ‘of the vestibule, which has the vestibule walls 31. It will be noted that this floor'overlaps the ends of the cars 2 and 50 3 formed by the end sill‘castings 38‘ and 39 that . The pillar or column 35 is provided with a later This yoke is 3mounted at 4| on the column 35, between the end sill castings 38 and 39. It extends out wardly and thence downwardly‘so that its lower ends 42 enter receiving-sockets‘ 43 in the upper margins on opposite sides of the casing.‘ This causes the vestibule and column 35 to rotate with the bolster I, while at the same time permitting free rocking movement of the vestibule to accom modate itself to the movements of the car bodies 70 so that its ?oor can be aligned substantially with ' r3 loperatio'n , When» it is desired to disassemble the joint, the 75 bolts‘ 8 and 9 are removed, the bolts l2, l3, l4 I 49,52: trunnions on the respective cars, a separable cen-' a horizontal axis, are made about the center 20 as these axes pass in vertical and horizontal di the floors of the cars 2 and 3. , by it may be removed without disturbing the re mainder of the combination. 3. In anarticulated car construction, a bolster,: 55 the car bodies,'whether about a vertical axis or 60 ally and downwardly extending yoke 40. Y‘ body and the-portion of the center plate occupied‘, carry the respective trunnions 22 and 25. These trunnions are- mounted‘ upon the under sides of the end sill castings 38 and 39 and depend‘ therefrom. All movements of the vestibule and rections throughthe center 20.» _ 2, In ‘an articulated car construction, a bolster, trunnions on the respective cars, and a separable center plate mounted on said bolster, and divided. -_ on a verticalwline, and adapted to supportsaid trunnions, whereby one trunnion withv its car ter plate mountedon said bolster, and divided‘. on a vertical line and adapted to support said. trunnions, whereby one trunnion with its car body andthe portion of the center plate occupied ; by it may beremoved without disturbing‘ the ,re--v mainder of the combination, and means of :sup-~ porting a vestibule in overlapping position with 1 respect to the car bodies when the articulation is assembled so arranged that when the trunnions and one portion of the center plate are disassem-Tiw; bled the support and positioningof the vestibule ~ are not disturbed. .~ '4.
