r1`his invention relates to improvements in ear construction. p

One object of the inventionis to provide a combined locking and center pin structure for connecting the body and truck holsters of railway cars, which is of rugged design and may be readily applied to andremoved from the holsters and has exceptionally great tensile strength to oppose forcible separation of the holsters and also great resistance against shearing action, wherein the combined locking and center pin structure comprises a pair of pin members which are separately and successively applied to the lholsters to facilitate the assembling operation' and are adapted to interlock to form a complete pin element, one of thepin membersvalso interlocking with one of the holsters to prevent relative rotation of the complete pin structure with respect to said bolster and accidental disengagement of the complete pin.

Another object of the invention is to provide a two partcoinbined locking and center pin for connectingthe body and truck holsters of a railway car, wherein one of the pin members has shouldered engagement ywith both holsters to prevent'relat-ive separation thereof and the other member also prevents separation of thebolsters when the same are rotated relatively to each other by shouldered engagement respectively with one of the holsters and the lirst namedmember.Y

A still further object of the invention is to provide a two part center pin of the character indicated in the preceding paragraph, wherein the member having shouldered engagement with both holsters has the shape of the means at one end thereof which has shouldered engagementwith one of thebolsters clearly appear from the description and claims hereinafter following.V

In the drawing, forming a part 'of this specification, Figure 1 is a top plan view of a portion of a body bolster of a railway car.

illustrating my improvements in connection therewith. Figure'2 is a vertical, sectional view through the body and truclr holsters of a railway car, corresponding substantially to the line 2-2 of Figure 1. Figure 3 is a vertical, sectional View taken in a plane at substantially right angles to the sectional Vview shown in Figure 2. Figures l 'and 5 bearing surfaces of substantially spherical form. The bearing block is provided with the usual upstanding annular vflange 15 which engages within the pocket v16 provided in the bearing projection of the body bolster.

In carrying out my invention, I provide the body bolster, the truck 'bolster and the bearingbloclr 13 with alin'ed centerfpinreceiving openings 1'?, 18 and 19 respectively. The openings 17, 18y and 19 are preferably of the same size and of. similar cross sectional outline. AAs most clearly illustrated in Fignres 4 and f5, each opening is of elongated cross sectional form, `the narrower Vpart of the opening being designated by 2O and the wider part by 21; The part 2O of jeach pin receiving opening has opposed walls 22 of cylindrical form whichV are concentric. The part 21 of each center pin receivingopening also has opposed substantially cylindrical walls 23-23 which are concentric with the walls 22-22 but Yoffset outwardly with respect to the same. As will be evident, the olfset'walls 23-23 of the pin receiving openings in effect form vertical slots at opposite sides ofthe pin recevingopenings, which term ,oef tle'partQl of said opening. As will be clear a pair of shoulders 25-25 are thus provided at opposite sides of the narrower part of the o ning 17.

The truc bolster is also provided with a pocket 26 beneath the pin receiving opening 18 thereof. The pocket 26 is in the form of a channel, defined by the vertical spaced webs 27-27 of the truck bolster. The width of the pocket 26 is at least as great as the diameter of the larger part 21 of the open- 1,8 and as shown corresponds in width to said diameter. Gpposcd shoulders 28-28 are thus provided at opposite sides of the narrower part 20 of the opening 18.

My improved center pin proper comprises a connecting member A and a locking member Bi The member A has a shank 29 which extends throu h the center pin receiving openin `of bot holsters. The shank 29 is of su stantially cylindrical outline in cross section and of such a diameter that it will fit within the narrower part 20 of the pin receiving 0 nings of the holsters. At the lower en t e shank 29 is provided with a pair of laterally projecting arcuate flanges 30-30 i at diametrica ly opposite sides thereof, which are adapted to cooperate with the shoulders 28 of the truck bolster. The flanges 30-30 m preferably of such a size that they will pass freely through the enlarged portions 21 of the pin receiving openings and will overlap the shoulders 28 when the member A is turned about its axis to an extent to register the Bauges 30 with the shoulders 28-28. The Hinges 30 are preferably' of such a length that they willoompletely overlie the shouldem. Immediately adjacent the head portion at',` the bottom end of the member A, the shank B9 of the same is cut away on opposite aides to provide vertically disposed grooves MMI, as clearly shown in Figure 5. At the upper endv the shank 29 is bifurcated, as

at 3232, thereby providing in efl `of vertically disposed parallel Lamis. `tfthe outer end of each arm 32, the member A has a `laterally projecting arcuate flange which corresponds inshape .ha'liao tlleange 30 at the op osite end o@ A` and is prefera ly vertillytllimdtherewith As will be evident, the together form a head memmit` ripper end of the memberA A havlg'dluldered engagement with the shouldeli u55 ofthe body bolster. The member A may be assembled with the body and truck holsters either by entering the same through the body bolster and passing the flanges -30 at the bottom end thereof through the laterally elongated portions of the pin receiving openings or by entering the same upwardl through the truck bolster and passing the anges 33-33 at the upper end thereof through the laterally elongated portions of said pin receiving openings.

The member B has a shank 34 which extends through the pin receiving openings of the holsters. At the upper end the shank 34 of the member B is provided with a substantially circular head 35 which bears on top of the flanges 33-33 of the member A. The head 35 is preferably of the same diameter as the head formed by the flanges 33-33 of the member A and is provided with an upstanding eye member 36 to facilitate handling of the member B in applying and removing the same. Adjacent the head 35, the shank 34 of the member B is of substantially the same diameter as the head 35 and the head `formed by the flanges 33 of the member A, fitting the larger part 21 of the pin receiving opening 17. The shank 34 is cut away at opposite sides, as indicated at 3T- 37, thereby providing vertically disposed grooves or slots adapted to accommodate the arms 32-32. At the lower end, the shank 34 is bifurcated, similarly to the upper end of the shank of the member A, thereby providing' a air of spaced arms 38-38 which embrace t e corresponding end of the shank ofthe member A and engage Within the grooves or slots 31--31 at opposite sides of said shank portion. At the bottom ends, the arms 3838 of the member B are provided with laterally projecting arcuate flanges 39-39 which fit between the flanges 30-30 at the bottom end of the member A and form a complete annular head therewith. The flanges 39--39 are of such a size that they will pass freely through the enlarged portions 21 of the pin receiving openings in assembling the member B with the body and truck bolsters. The major portion of the shank 34 of the member B corresponds in diameter to the narrower parts 20 of the pin receiving openings, as clearly shown in Figures 2 and 3, t-he upper end portion of the shank 34 immediately adjacent the head 35 only being enlarged as hereinbefore pointed out.

, In applying my improved center pin to the body and truck holsters of a railway car for connecting the same, the member A is first applied either by insertion through the truck or body bolster. Assuming that the member A is applied by inserting the same upwardly through the truck bolster, the lugs or flanges 33-1-33at the upper end of the same are registered with the larger parts 21 of the pin receiving openings and passed therethrough. After the member A has been completely inbody bolster.

serted, the same is given a turn about its axis so as to aline the flanges 33-33 with the' shouL ders 25-25 of the bodybolster. At the same time, the flanges -30 at the bottom end of the member A will also be registered with the shoulders 28-28 of the truck bolster. As

will be evident, theheads formed by the flanges at opposite ends of the member A will thus prevent separation of the body and truck bolsters. Instead of inserting the member A upwardly through the truck bolster, the same may be applied by passing the same downwardly through the body bolster, as herein before pointed out. In this operation, the flanges 30-30 of the bottom head of the member A are first brought into the alinement with the larger portions 21 of the pin receiving openings and passed downwardly through said openings. When the member A has been completely inserted, the same is turned in the manner hereinbefore pointed out to register the flanges at opposite ends thereofl with the shoulders of the body and truck bolsters respectively.

After the member A has been applied, thek locking member B is inserted through thc top of the pocket 24 of the body bolster, the arms 88 being entered into the pin receiving openings at opposite sides of the shank of the member A, the flanges 39-39 passing through the laterally enlarged portions 21 of the pin receiving opening. When the member B has been completely applied, the forked portion thereof embraces the shank 29 of the S member A at the lower end of the latter and the forked portion of the member A embraces the upper portion of the shank 34 of the member B, thereby interlocking the members A and B so that they are held against relative rotation with respect to each other. Inas much as the upper end portion of the shank of the member B fits the larger portion 2l, of the pin receiving opening 17, the member B is held against rotation with respect to the As the members A and B are interlocked, the entire pin is also held against rotation with respect tothe bodybolster.

`When t-he body and truck bolsters of the car are in transverse alinement, asy for example when the car is vrunning on straight track, the member A has shouldered engagement with both bolsters, thereby preventing separation ofthe same, the flanges 39-39 at the bottom end of the member B at this time F heing out of alinement with theshoulders 28 'of truck bolster. When the car is operated on curved track, the body and truck bolsters will be turned angularly relative to each other and inasmuch as the complete pin is locked against 28'-28of the'truck bolster, thereby assisting in locking the bolsters together. In this connection, it is pointed out that any tendency of the bolsters to separate in a vertical direction will cause a lifting of the head formed by the flanges ofthe member A, thereby also lifting the head 35 of the member B and bringing the flanges 39-39 at the lower end of the member B into engagement with the shoulders 28 of the truck bolster.

In separating the body and truck bolsters, the member B is first removed by lifting the same upwardly through the body bolster, thus withdrawing the same from engagement with the member A. After the member B has been removed, the member A may be freely rotated to register the flanges thereof with the portions 2l of the pin receiving openings. The member A may then be withdrawn either by lifting the same upwardly through the body bolster or dropping the same through the truck bolster.

From the preceding description taken in connection with the drawings, it will be evident that I have provided an exceedingly efficient and rugged center pin member of the -two part type, wherein additional strength is provided by a continuous head member, which is formed partly on each section of the pin. Further, maximum tensile strength opposing separation of the body and truck bolsters is had by providing means on both members ofthe pin for locking the same to the bolsters.
