MINER, INC, OF CHICAGO, ILLINOIS, A. CORPORATION OF DELAWARE CAR CONSTRUCTION Application filed. January 24, 1829, Serial No. 334,693.

This invention relates to improvements in car construction.

One object of the invention is to provide a combined locking and center pin arrangement for railway car bolsters, of rugged design, which may be readily applied and effectively locked against accidental re moval, including a pair of locking elements having headed portions at opposite ends, having shouldered engagement with the bolsters, and a central filler member for holding said elements separated, said filler member having means at the opposite ends thereof having shouldered engagement with the elements to lock the same together, said means at both ends of the filler member being of such a cross section that when the filler is in oneposition it will pass freely between said elements and when it is turned to another position passage of said means between said elements is prevented.

A further object of the invention is to provide a center pin arrangement of the character indicated in the preceding paragraph, wherein means is provided for looking the filler member and the elements against relative rotation in their completely assembled condition.

Another object of the invention is to provide a combined locking and center pin arrangement for connecting the body and truck bolsters of a railway car having aligned center pin receiving openings and retaining shoulders adjacent said openings, including a center pin comprising a pair of outer members and a filler, said outer members each having laterally projecting exterior flanges at opposite ends cooperating respectively with the shoulders of the body and truck bolsters, the flanges at corre sponding ends of said members together defining head portions of the pin, the filler member maintaining the outer members separated to hold the flanges thereof in overlapping relation with the retaining shoulders of the bolsters, the filler member being provided with retaining means at opposite ends thereof, engageable with the opposite ends of said outer members to lock the parts together, the retaining Renewed December 5, 1929.

means at both ends of said filler member comprising pairs of lugs which, when registered with the opening between said outer members, will pass freely therebetween and when displaced angularly by rotation of said filler member will overlap the corresponding ends of said outer members.

A still further object of the invention is to provide a combined locking and center pin arrangement of the character indicated in the preceding paragraph, wherein the center pin receiving openings of the bolsters are slotted at opposite sides to accommodate portions of the flanges of the outer members, thus permitting the employment of flange members of relatively large size and great strength, thus adding greatly to the ruggedness of the center pin member.

Other and further objects of the invention will more clearly appear from the description and claims hereinafter following.

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, corresponding substantially to the line 22 of Figural. Figure 3 is a horizontal sectional View, corresponding substantially to the line 33 of Figure 2. And Fi ure l is a detailed perspective view of a retaining member employed in connection with my improved center pin construction.

In said drawing, the body bolster of the car is designated by and the cooperating truck bolster by 11. The bolsters proper may be of any suitable construction and, as shown, the body bolster is provided with the usual top and bottom webs connected by a tubular section 12. At the bottom, the bolster 10 is provided with the usual hearing projection 13 which is of substantially spherical form and is seated in a cooperating bearing plate 14 which is mounted on top of the truck bolster 11.

The truck bolster 11 is also provided with the usual top and bottom webs which are connected by transverse vertical walls defining a pocket 15.

In carrying out my invention, I provide the body bolster with a center pin receiving opening 16, and the truck bolster and hearing plate 14 mounted thereon with openings 17 and 18 in alignment with the opening 16 and of the same diameter, also adapted to accommodate the center pin member. The major portion of the tubular section 12 of the body bolster is 01' considerably greater diameter than the pin receiving opening 16, thereby providing a pocket to accommodate the upper head member of the center pin and an annular shoulder 19 at the bottom of the pocket which cooperates with the head of the pin.

The vertical walls of the truck bolster are spaced apart a distance greater than the diameter of the pin receiving opening;v 17 of bolster, thereby providing an annular retaining shoulder 20 adjacent the pin. receiving opening 17 at the upper end of the pocket 15. As will be evident upon reference to Figure 2, the shoulders 19 and 20 of the two bolsters are relatively close together, thereby pern'iitting the use of a short center pin member.

My improved center pin proper comprises a pair of outer members A-A, a central filler 0-r spacer B, and a retaining member C.

The members A are of similar design, and together form a substantially tubular outer section of the pin. Eaah of the members A is oi are shape horizontal cross section, as most clearly shown in Figures 1 and At diametrically opposite sides of the center pin, the sections A are spaced apart, as clear- Ly shown in Figures 1 and 3, to provide vertical passageways between said members, for a purpose hereinafter described. At the top and bottom ends, each member A is provided with laterally outwardly projecting horizontal flanges 21-21 which, when the parts of the pin are assembled, cooperate with the annular shoulders of the body and truck bolsters to lock the same together.

The flange members 21, at the upper ends of the members A, form a substantially complete head member at the top of the pin.

he flanges 21, at the bottom ends of the members A, form a similar head member. The portions of the members A, between the heads 21, define the shank of the center pin and present exterior cylindrical surfaces which substantially fit the walls of the center pin receiving openings 16, 17 and 18. The center in is provided with a central bore adapte to accommodate the filler member B, the opposed inner wall portions of the members A being recessed, as indicated at 2222, to accommodate diametrically opposite sides of the shank portion of the member B. As most clearly shown in Figure 1, the flange members 21 of each member A are (o-extensive with the main body portions of said members, thereby providing the center pin with head portions of relatively heavy construction.

The filler member B comprises a cylindrical shank portion 23 which fits between the members A and has diametrically oppw site side portions seated within the openings 22 of said members. At the bottom end, the shank 23 is provided with an enlarged portion forming a head member 24;. The enlargement 24 comprises a pair of lugs at diametrically opposite sides of the shank, which engage the bottom ends of the members A. At the upper end, the shank 2 of the member B also provided with an enlargement 25 forming an upper head portion. The enlargement 25 comprises a pair of lugs disposed at. diametrically opposite sides of the member B and in vertical akignment with the lugs of the head 24. The lugs of both heads are of such a width as to pass lock the members A together and prevent relative movement of the members A and B with respect to each other in an endwise direction. As shown, the heads 2* and 25 closely fit the members A, thereby reinforcing the flanges 21. When the filler member B is removed from between the members A, the latter may be displaced inwardly toward each other, thereby collapsing or contracting the pin so as to facilitate application and removat thereof.

The walls of the center pin receiving openings 16, 17 and .18 are recessed at diametrically opposite sides, as indicated by 2626, to present vertical, guide slots adapted to accommodate the inner extremities of the flanges 21 at opposite sides of each of the members A when the pin is collapsed or contracted. The of the pin are so proportioned that the members A may be successively inserted, each. member being oi? such a size that the outer edges of the flanges 21 at opposite ends thereof will, clear the wall portions of the center pin receiving openings of the bolsters and the opposite inner end edges of each of said thrnges will pass thron h the openings 26, the curved end edges oi these flanges being preferably concentric with the curved outer faces of the shank portions of the members A.

The retaining member C is in. the form of a U-shaped clip having spaced arms 27%? and a transverse connecting portion 28 at the upper end thereof. \Vhen the parts are assembled, the member C has the arms 24' Ill) thereof disposed on opposite sides of the shank oi the, filler member 13 within the guideways or openings between the members A.

res 2 and i the arms- 2-7 poi ions the arms 27 are rounded on their outer sides, as inui dat 3.0-30, said rounded portions lying in substantially the seine "ndrical surface. as the outer surfaces C1; the members A. The upper por tiens of the arms 27 arelaterally enlarged, as indicated t 3-13l, the enlarged portions being 0. such a length that the bott m portio thereof are seated the recesses 26 of the side walls of the pin receiving opening 16; As be erident, the arms 27 of the retaining member G being disposed between the members A will be held a rotation with respect to the same, and the transverse upper section 28 being seated inthe pocket 29. of the id. or member B willI hold the lat cgainst rotation and all the parts will thus belocked together relative rote.- tion. about the axis of the pin. It is further pointed out that by e1- .gement oi the lower a end portions of the enlargements 33. with:

will.

they 1 co. 26., the entire center pin stuc- "t I: F".1 l 17 l we v m -n 1 6 tie vii 3e iocier a ainst rkioublvn m n respect to the bolster 10-, The inner edges oi; the arms 27 are also rounded oii so as to the oppos sides oi, the cy Lndrical shank portion 2 the filler member B. In. order facilitate the removal of the reaming member C, the same is pro ided With an upstanding central lug portion 32. having opening 33 within which a removing tool may be engaged.

in applying the center pin to the bolsters 10 and 11, one of the members A is first inserted either through the body or truck bolster by passing the flange portion 21 at the corresponding end: of the in er A tl *ough the pin receiving openings and bringing the flanges at the opposite ends thereof into cooperative relation with the corresponding annular shoulders of the two bolsters. This member is then displaced laterally outwardly to overlap the flanges with the shoulders and bring the shank into con tact with the corresponding side wall portions of the center pin openings. Suflicient clearance is thus. provided to permit insertion of the other member A. The latter is then, inserted in a. similar manner and displaced. laterally outwardly to engage the flanges thereof with the retaining shoulders of the bolsters. \Vhen the members A have been thus assembled with they bolsters and spread apart, sufficient clearance is provided between the same to accommodate the filler member B. The f'ller member B is then inserted between the inen'ibers A. by passing the upwardly through the pocket or the bolster or downwardly through the of the body bolster. At this time, the lugs forming the h ads 24 and #5 are so disposed as to register with the pessageways etween the members A. When the filler has been hilly inserted so that the heads 2% and 25 are disposed respectively below and above the corresp nd'ing ends of the members A, tl e filler member is given :1 quarter turn so as to dispose the lugs forming the heads and 25 shown in Figures 1 and'2. When the heads are thus positioned, the parts A and B. are locked against relative displacement in endwise direction and the members A are held in their outermost position. with the flanges thereof overle ping the shoulders of the body and truck bolsters. The retaining member C is a; plied by the same through the pocket of the body bolster end engaging the arms 27 thereof within the passageweys di etrically oppositesides of the 1, between the members AK.

The retaining element is passed downwardly until the transverse section 28 ther of is seated within the pocket 29 of the head 25.. As hereinbefore pointed out, all i' the parts of the pin are thusloeke relative rotation. lVhen theret. ber has been fully applied, enla Si or the arms will engage within the recesses.1?, es hereinbetore pointed out, there by preventing rotation of the center pin with respect to the body bolster. Although the center pin has been described and showr as locked he body bolster, it will be e" oer-1t that my invention is not limited. to th s ecise construction and that the enlargeng member may be omitted, thereby allowing relative rotation of the center structure asv a unit with respectto both bolsters. lVith the enlargements 31 omitted, the arms 27 will be looked between the members A. and the retaining member will be locked to the: filler B by the transverse section 28, thus interlocking all bAMu of th parts of the pin against relative rotamen.

so as to contract or collapse the head portions of the pin formed by the flanges 21 thereof and permit withdrawal of the displaced member. After removal of said member, the other member A is displaced laterally inwardly to register the flanges thereof with the openings and guidcways so as to permit withdrawal oi? the same.

W'hile have herein shown and described what I consider the preferred manner of carrying out my invention, the same is merely illustrative and I contenn vlate all changes and modifications which come within the scope of the claims appended hereto.
