Definitions

  • One object of the invention is to provide a locking center pin for railway cars, connecting the body and truck bolsters, comprising two elongated sections extending through the usual center pin receiving Openings of the bolsters, each' section being headed at opposite ends to shoulder against the bolsters at said openings, wherein the sections are held spread apart and in shouldered engagement with said bolsters by a laterally projecting enlargement on the inner side of each section bearing on the inner side of the other section, said enlargements being at opposite endsof the pin and the engagement being on fiat vertical surfaces, thereby preventing accidental relative vertical displacement of th'e sections of the pin with respect to each other to an extent to allow collapse of the pin with resultant failure of the. same performing its function sters together.
  • a more specific object of the invention is to provide a center pin as set forth in the preceding paragraph, wherein the lower end of the pin where it extends through" the bearing opening of the truck bolster presents maximum resistance to transverse shearing forces by providing relatively large areas of contact between the sections thereof along the inner sides of said lower end portions.
  • Figure 1 is a verticalsectional view, lengthwise of a railway car, through the body and truck bolsters thereof, illustrating my improvements in ⁇ connection therewith.
  • Figure 2 is a view, similar to Figure 1, partly broken away, illustrating the manner of applying my improved locking center pin.
  • Figure 3 is a side elevational view of the 40 bottom end portion of my improved lockingr center pin, looking from right to left in Figure 1.
  • Figure 4 is a top plan view of the improved lockingcenter pin.
  • Figure 5 is a bottom plan view of the improved locking center pin, looking upwardly in Figure 1.
  • I I indicates the body bolster of the car and I2 the truck bolster.
  • the body bolster includes the usual center sill structure I3 and diaphragm sections I 4 extending from the 50 sill at the body bolster portion thereof.
  • the center sill is provided with' the usual filler casting I5 having al center section IB to accommodate the locking center pin.
  • the section I6 is of cylindrical tubular form. as shown, and presentsI a o f lockinguthe bol- 20
  • the truck bolster I2 has top and bottom walls I 8 and I9, connecting side walls 20, only one of which' is shown', and spaced, laterally extending. vertical walls 2I2
  • the spaced walls 2I--2I define a pocket 22 therebetween which serves to accommodate the bottom head of the center pin connecting the holsters.
  • the body bolster II including the center sill I3 is supported on the top wall of the truck bolster by means of the usual center plate 23 fixed to the body bolster', and which has a depending cylindrical bearing projection 2t seated in the bearing pocket provided by an upstanding annular rib 25 on the top wall of the truck bolster.
  • 'I'he truck bolster is provided with a tubular sleeve section 26 formed by upstanding and depending annular anges projecting from the top and bottom'sides of the wall I8 of the truck bolster.
  • the sleeve 2B is of the same diameter as the sleeve I6 of the body bolster and is in vertical alignment with the sleeve I6.
  • the upstanding flange portion of the sleeve 26 extends into and has bearing engagement with a central pocket 2l of the center plate 23.
  • the bottom end of the depending flange portion of the sleeve 26 presents a downwardly facing, annular abutment shoulder 28 surrounding the opening of the sleeve with which the head portion at ythe lower end of my improved locking center pin is adapted to c ⁇ ooperate.
  • -the bottom wall I9 of th'e truck bolster is provided' with an opening 29 therethroughv which communicates with the pocket 22 and through which the center pin is passed in applying the same to the body and truck holsters.
  • My improved locking center pin serves to connect the body and truck bolsters of the railway -car and lock the same against vertical separation. and comprises broadly two elongated sections or members A and B, which are headed at opposite ends. ,i
  • each member is of substantially semi-cylindrical cross section and is provided at the top thereof with an eccentric, substantially semi-cylindrical, outstanding flange 30 and with a concentric, substantially semi-cylindrical, outstanding flange 3l at the bottom end thereof.
  • the iianges 30 and 3l form top and bottom head members of the members Aand B. which are at opposite ends or the mank portions o: said substantially flat, vertically extending, transverse face 32.
  • the member B has a laterally inwardly extending flange or lug 33 projecting from the face 32.
  • the lug 33 has its top face in transverse alignment with the top surface of the flange 33 at the upper end of the member B and is cut away on an incline or beveled oif at its underneath side, as indicated at 3l.
  • the transverse. vertical side face oi' the lug 33 is substantially flat and in the applied condition of the pin bears;ilatly on the inner side face 35 of the head formed by the ange 33 at the upper end of the member A.
  • the member A is laterally inwardly enlarged at-its lower end, as indicated at 3B, said enlarged portion presenting a vertically extending, substantially flat, transverse surface 3l' adapted to bear flatly on the inner face 32 of the member B.
  • the inner side of the member A above the surface 31 is inclined away from the inner side of the member B, that is, the inner side of the member A presents an inclined surface 33 on its inner side which extends approximately to the flange 30 at the upper end of said member A where the member A presents the vertical at face 35 hereinbefore referred to.
  • the member A is beveled or inclined, as indicated at 33, to facilitate assembling of the pin with the bolster, the beveled face 33 cooperating with the beveled face 34 of the lug 33 of the member B to cam or spread the members A and B apart at their upper ends and bring the flange 30 of the member A into overhanging relation with the shoulder l1 of the body bolster.
  • the vertically extending surface 31 of the enlarged portion at the lower end of the member A extends upwardly a considerable distance into the sleeve 26 of the truck bolster well beyond the Iplane of the bearing connection between the center plate of the body bolster and the truck bolster and has true flat bearing engagement throughout its height with the inner flat face 32 of the member B, thereby greatly strengthening the lower portion of the assembled pin to resist transverse shear at the bearing connection between the holsters.
  • the eccentric flanges 30-30 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 holsters 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 member A is inclined and the pin is contracted with the member B in the position shown in Figure 2.
  • Each member A and B is preferably provided with a depending, perforated ear 40 at its lower end adapted to receive a cotter pin 4i.
  • when engaged through the ears lil-40 holds the two members A and B against vertical separation.
  • the member B is first inserted in the center pin openings of the holsters by passing the same upwardly through said openings until the upper head or flange 33 thereof reaches a position above the shoulder I1 of the body bolster.
  • the member B is displaced laterally outwardly to engage the flange 30 thereof over said shoulder. as shown in Figure 1, and the ange 3i beneath the shoulder 23 of the sleeve 28 of the truck bolster.
  • the member A is then inserted upwardly in the bolster openings and inclined, as shown in Figure 2.
  • the operation is substantially the reverse of that just described, the member B being pushed upwardly until it provides suillcient clearance for the head 30 of the member A to pass beneath the lug 33, as shown in Figure 2, so that the member A may drop out or be pulled forcibly downwardly.
  • the number of members making up the complete expandible pin may be reduced to a minimum, or two in number, and yet give the maximum overlap of the heads with respect to the shoulders at the pin receiving openings of the holsters to provide the required strength.
  • the combination with body and truck holsters having bearing engagement with each other on a horizontal plane and provided with vertically aligned, center pin receiving openings; of a two-part sectional center pin insertable in said openings, one of said parts comprising an elongated member having heads at the top and bottom ends, said member having a flat vertical inner side face and a laterally inwardly offset enlargement extending from said side face at the upper end of said member, said enlargement having a, vertical inner side face, the other of said parts comprising a second elongated member having heads at the top and bottom ends, said second member increasing in thickness toward its lower end and having vertical flat inner side faces at its upper and lower ends connected by an elongated inclined inner side surface, said lower vertical side face extending from the lower end of said member upwardly beyond the horizontal plane of bearing engagement between said bolsters, and bearing on the at vertical inner side face of said first named member, said upper vertical face of said second named member abutting 1 the vertical inner side face of the enlargement
