  • the body bolster is interlocked with the truck holster* bymy improved locking center pin which comprises broadly tvvo elongated sections ⁇ or members A and B, which are headed ⁇ at opposite ends. rThe two members. A and B are off the same design,
  • EachmemberV is of substantially semi-cylindrical cross section andis provided at theitopithereoi with an; o o-s ⁇ centric, substantially semi-cylindrical, outstanding flange 28, and with a concentric, substantially semi-cylindrical, outstanding flange 29 at the bottom end thereof.
  • the flanges 28 and 29 -form top and bottom head members of the members A and B, which head members are at opposite ends of the shank portions of said members A and B.
  • each member A and B presents a substantially flat, vertically extending, transverse face 30.
  • the member A has a laterally inwardly extending ange or lug 3
  • has its underneath face in transverse alignment with the underneath face of the iiange 29 at the lower end of said member, and is cut away on an incline, or beveled off at the upper side, as indicated at 32.
  • the transverse, vertical side face of said lug is substantially flat and, in the ap- Vpliedcondition of the pin, bears on the flat, inner side face 30 of the member B at the lower end of the latter.
  • the member B is provided ⁇ with a laterally inwardly extending ange or lug at the upper end thereof, projecting from its inner side, which lug is similar to the lug 3
  • of the member B bears on the inner side of the member A, that is, on the flat surface 3G thereof.
  • the lugs 3 I-3I of the members A and B hold these members spread apart with the heads or flanges 28-28 overlapping the annular shoulder I1 provided by the ange I6 of the body bolster II and the flanges 29-29 cooperating with the shoulder presented by the top wall of the pocket 24 of the truckl bolster I2 to restrict upward movement of the pin.
  • the member A is beveled off at the upper end on the inner side to provide an incline or cam face 33.

  • of the member B forms a cam face cooperating with the cam face 33 of the member A to cam the upper end of the latter outwardly
  • the inclined face 32 at the lower end ofthe member A forms a cam face cooperating with the lower end Yof the member B to cam Y said memberA outwardly at its lower end during application of the center pin to the bolsters, as hereinafter pointed out.
  • the eccentric iianges 28-28 at the top ends of the members A and B are of Such a size that they will pass freely through the pin receiving openings of both the body and truck bolsters when the pin is contracted, that is, the top head of the member B is of such a size and outside contour that it will pass freely upwardly and downwardly through the center pin receiving openings of the bolsters when the member A is absent, and the head of the member A is of such a size and outside contour that it will pass freely through said openings when the pin is contracted with the member B in position and with the inner side of the member A abutting the inner side of the member B.
  • the member B is first inserted in the center pin openings of the bolsters by passing the same upwardly through said openings until the upper header flange 28 thereof reaches a position above the shoulder I1 of the body bolster.
  • the member B is displaced laterally outwardly to engage the flange 28 thereof over said shoulder, as shown in Figure 2, and the ange 29 beneath the shoulder of the opening of the truck bolster.
  • the member A is then inserted upwardly in the bolster openings in parallelism with the member B, as illustrated by the dotted line position of the member A in Figure 5.
  • the upper end of the member A is cammed laterally outwardly away from the member B by the cam face 33 of the member A engaging with the underneath cam face 32 of the member B, thereby engaging the head or flange 28 of the member A over the shoulder I1, as shown in Figure 6, at the same time permitting the member B to drop to the position shown in Figure 2.
  • the upper end of the pin is thus held spread apart by the lug 3
  • the weight of the member B of the pin will effectively prevent the same from working upwardly to a position wherein the upper head end of the member A could slip below the lug 3
  • the member B may be provided with a depending perforated lug 34 at its lower end adjacent the inner side, through which a bolt'35 is engaged, the nut 36 of which shoulders against the lower end of the member A.” Upward movement or displacement of the member B with respect to the member A is thus positively prevented.
  • my improved center pin comprises two members C and D which differ slightly from the members A and B hereinbefore described.
  • the members C and D are provided with outstanding flanges I28-I28 at their v upper ends which are in all respects similar to the flanges 28-28 of the members A and B hereinbefore described, with the exception that the underneath faces of the flanges are beveled, as indicated at
