ARTICULATED CARS Filed March 3, 1955 2 Sheets-Sheet 2 INVENTOR. Harry J. Horbuluk BY ATTORNEYS II III FIG? United States Patent ARTICULATED CARS Application March 3, 1955, Serial No. 491,906
11 Claims. (Cl. 105-4) The present invention relates to railway cars in general and in particular to articulated cars intended for mine or industrial haulage.
The majority of railway cars are mounted on individual trucks at each end, thus the number of trucks in a train is always two times the number of cars. This is expensive and the expense can, in certain cases, be reduced by articulating the cars so that the number of trucks in a train is only the number of cars plus one. In mine and industrial haulage the tendency has been toward greater capacity cars and these cars must be made as cheaply as possible in order to compete with other types of haulage. In order to provide the necessary movement between the car bodies, it is necessary to provide for longitudinal movement and turning movements. It is also necessary for the supporting trucks to be properly guided or controlled.
It is an object, therefore, of the present invention to provide a train composed of articulated cars having the bodies spaced apart and supported by trucks located at the space between the bodies.
A further object of the invention is the provision of a train of articulated car bodies connected together by resilient coupling means permitting rotational and sliding movement between the bodies and between the bodies and supporting truck.
A still further object of the invention is the provision of a train of articulated car bodies, which bodies are coupled together by a combined center pin and coupling pin which is resiliently held centered between the car bodies.
A yet further object of the invention is the provision of a train of articulated car bodies, each body and truck of which is provided with interengaging resilient means controlling the truck movements.
These and other objects of the invention will be apparent from a study of the following description and accompanying drawings, in which:
Fig. 1 is an elevational view of a three-car train.
Fig. 2 is an enlarged plan view partly in section to show the connection between the car bodies.
Fig. 3 is an enlarged sectional view taken substantially on line 3-3 of Fig. 2.
Fig. 4 is an enlarged view showing the relation of the supporting and connecting parts under buff conditions.
Fig. 5 is a plan view showing a supporting truck and further showing certain body parts in section.
Fig. 6 is a sectional view taken substantially on line 66'of Fig. 5, and
Fig. 7 is a sectional view taken substantially on line 7-7 of Fig. 5.
Referring now to the drawings in detail it will be seen that the train is composed of any desired number of bodies such as A, B and C supported on trucks T located at the ends of the train and at the spaces between the bodies. Each body is preferably made with sides 2 joined by suitable floor structure and by sloping end walls 4. These sloping end walls are supported on an I beam bolster 6 having the upper flange tipped by bending the web so thatthe flange is parallel to the sloping floor 4. In order to stiffen the bolster it is braced internally by vertically extending braces 8 and externally by buttress plates 10 certain of which are inclined inwardly toward the center of the car. These buttress plates 10 are welded or otherwise secured to a center bearing support means constituted by a roughly triangular shaped supporting plate 12 extending beneath and rigidly attached to the bottom of the body bolster. These supporting plates extend laterally outward from the body bolster and have their central portion pierced to provide longitudinally elongated slots 14. Each supporting plate: is also provided with a downwardly extending projection 16 located substantially on the center line of the car and projecting.
downwardly sufiicient to be in the path of movement of the supporting truck T.
The bolster web is preferably pierced substantially on the longitudinal center line and is bushed as at 18 to receive a coupling shank or drawbar 20. The inner ends of the shanks are threaded to receive a nut and washer assembly 22 by means of which the resilient springs 24.
. be seen that the supporting truck T is provided with two:
projections.
As shown, particularly in Figs. 2, 3 and 4 the support ing plates 12 of each car are supported by the truck bolster 36. In normal condition the elongated slots 14 are in alignment and positioned above a central hole 50 formed in the bolster top plate 38. A combined coupling pin and center pin 52 is adapted to extend vertically through truck bolster hole 50, elongated slots 14 and holes 54 formed in the jaws and eye of the coupling. This pin will, through the coupling shanks, transmit all buff and draft while holding the car bodies for rotation about the center of the truck. Sliding movements will Patented Oct. 21, 1958 be permitted between the car bodies and between the bodies and trucks due to the elongated slots 14.- In other words, when bodies A and B move toward each other under buff forces the parts will assume the position as shown in Fig. 4. When it is desired to remove a car body from the train, it is only necessary to lift the combined coupling and center pin, after which the adjacent end of the body to be removed is supported on suitable jacks or other lifting device and the adjacent body pulled outof position. ends of the train are duplicates of the trucks between the car bodies and can be coupled to the locomotive or haulage cable by means of a coupling. link- 60 (Fig. which has its inner end engaged by the combined coupling and center pin 52. Fromthe preceding it will beseen that the train is extremely flexible with each body being rotatable with respect to each other and to the truck and also longitudinally slidable. It will also be seen that each truck, whether mounted between the car bodies or at the ends of the train, has its movement guided and controlled by the resilient butters and body projections.
While the' invention has been described more or less in detail with specific reference to the drawings, it will be obvious that various modifications and rearrangements of parts may be made without departing from the scope of the invention as defined in the following claims.
