This invention relates to improvements in car construction. 7

One object of the invention is to provide a connecting means for body and truck bolsters of railway cars in the form of a combined locking and center pin composed of a plurality of sections which may be readily applied and removed, and has shouldered engagement with the bolsters, wherein maximum strength is had by providing relatively large complete annular head members at opposite ends of the pin comprising enlargements at opposite ends of each section.

Another object of the invention is to provide a combined locking and'center pin for body and truck bolsters of railway cars having alined center pin receiving openings, each provided. with a shoulder at the outer end of its opening, wherein the center pin is composed of a plurality'of sections including a pair of outer members and a combined filler and spreading member therebetween, each outer member and the filler member having heads at opposite ends thereof, and the shoulders of the bolsters are cut away to provide clearance in assembling the sections with the bolsters, and the assembled pin is rotatable to'bring the head members of the filler in shouldered engagement with the bolsters and the filler member is locked against reverse rotation with respect to one of said bolsters to prevent disengagement of the head members thereof from the corresponding shoulders.

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

In the drawing, forming a part of this s oecification, Figure 1 is atop plan iew of a portion of the body bolster of a railway car illustrating my in'iprovemcnts in connection therewith. Figure 2 isa vertical, sectional view corresponding substantially to the line 22 of Figure 1. Figure 3 is a vertical, sectional view substantially in a plane at right angles to the vertical, sectional View shown in Figure 2. And Figure l is a horizontal, sectional view corresponding substantially to the line 4 -4 of Figure 2.

to In saiddrawings, designates a-body bolster and 11 the truck bolster of a railway can. The truck bolster is .provided withthe usual bearing blopk 12 at the top thereof seated in a pocket 13 on the bolster. The body bolster is provided with a depending, cooperating bearing projection 14, which is of convex spherical formation and cooperates with the concave top bearing surface on the block 12. The block 12-is also provided with an annular upstanding flange 15 which enwithin the usual pocket 16 provided at the bottom of the body bolster.

In carrying out my invention, I provide the body and truck bolsters "'ith alined center pin. receiving openings 17 and 18. The bearing bloclr12 is also provided with an opening 19, which registers with the openings'lt' and 18. The openings of thebody and truck bolsters and the bearing block are preferably of cylindrical cross section and of the same size. Below the. pin receiving opening 18 of the truck bolster, a relatively large pocket 20 is provided, which, as shown, is of considerably greater width than the pin receiving opening 18, thereby providing a retaining shoulder 21 at the bottom end of said opening.

he body bolster is also provided with a relatively large pocket 22 above the center pin receiving opening 17 thereof, which is of greater width than said opening, thereby providing an annular retaining shoulder 23 surrounding said opening at the uper end therea of. At the upper endof'the pocket 22, the truck bolster walls are recessed atdiametrically opposite sides as indicated at 2525, fora purpose hereinafter pointed out. The walls of the openin s 17 and 18.01 the body and truck bolsters and the opening 19 of the bearingblocl: 12 are vertically slotted at'diametrically opposite sides, as indicated at The slots 2 l24l extend through the shoulders 21 and 23: of the truck and body bolsters, thereby cutting away portions of the shoulders and leaving supporting ledges on diametrically opposite sides of the pin receiving openings. 7

My impr ved combined locking and center pin co-mprisesbroadly a pair of outer members AA and a central filler or spreading member B.

The members A are of similar design, each having a shank portion extending through the pin receiving openings and head members 26-26 at the top and bottom ends of the shah]: portion. The shank of each member A has a fiat inner face and a curved outer surface which corresponds substanllyto the curvature of the corresponding wall portions of the pin receiving openings of the bolsters. The head members 26 are in the form of arcuate flange elements which are of such a size that they will pass through the pin receiving openings of the bolsters when the end portions of the flanges are alined with the slots 24 so as to pass through the some. The head members 26 correspond in to the ledges of the shoulders and preferably eo-extensive therewith. When the two sections A are spread apart, as clearly shown in Figures 3 and 4, the head portions thereof overhang the retaining shoulders of the body and truck bolsters, thereby preventing separation of the bolstem.

The combined filler and spreader member Bis in the form of a relatively wide flat plate having enlargements 27 and 28 at the top and bottom ends thereof respectively. The enlargements 27 and 28 form head portions ada ted to cooperate with the reta1nin shoul ers of the body and truck bolsters. enlargements 27 and 28 are of such a size that they pass freely through the slots 24 in assembling the parts, while the filler member is being inserted within the openings of the bolsters between the members As will be evident, when the assembled pin is rotated about its axis, the head members 27 and 28 at the top and bottom ends of the filler member B will be brought into shouldered en agement with the retaining shoultiers of the body and truck bolsters.

. Asdnost clearly illustrated in Figure 1, the recesses -25 at the upper end of the pocket 22 of the body bolster are located in a vertical plane at an angle of 90 to an axial plane passing through the slots 24. When the head portions of the filler member are lgoufiit into shouldered engagement with t ea lsters, the filler plate is disposed in alinement with the recesses 2525. In order to prevent backward rotation of the filler with respect to the body bolster, a

ch 29 is employed, which is interldcked iii the body bolster and the filler ping, As most clearly shown in Figures 2 ma the clip 29 is of U-shape form and'has the opposite ends thereof seated in the re- 25 and the side members closely embracing the top end portion of the filler plate B.

As clearly shown in Figure 2, both the um! members A-A and the filler plate B are provided with eye members at the top thereof to facilitate handling of the same and withdrawal of the parts from the center pin receiving openings of the bolsters. As most clearly shown in Figgure 3, the upper end portion of the plate is laterally enlarged, thereby providing shouldered engagement with the upper ends of the members A, as indicated at -30. This shouldercd engagement between the plate B and the members A prevents the plate from dropping between the members A.

In applying my improved combined locking and center pin to the bolsters of a railway car, the sections A-A may be inserted either through the top of the body bolster or upwardly through the bottom of the truck bolster. The sections A are inserted successively. Assuming that the section A, shown at the lefthand side of Figure 3, is first applied, the head portions thereof are so disposed as to register with the slots 24 of the bolsters. When in this position, the section A referred to may be freely inserted through the openings of the two bolsters. After having been completely inserted, this section is displaced laterally so as to overlap the head portions thereof with the shoulders of the body and truck bolsters respectively. The other section A is then applied in a similar manner, it being evident that the first section when displaced laterally entirely clears the slots 24 so as to permit passage of the head portions of the second section A. When the two sections have been spread apart, as shown in Figure 3, the filler plate B is applied therebetween by inserting the same through the top of the body bolster. lVhen the filler plate has been completel inserted, the head members at the top and bottom ends thereof are disposed respectively above and below the retaining shoulders of the body and truck bolsters. With the parts thus assembled, the pin is rotated about its vertical axis through an angle of 90, thereby bringing the filler plate into alinement with the recesses 25-25 of the pocket 22 of the body bolster. As will be evident, when the parts are thus positioned, the filler plate has shoulderedengagement with both the body and truck bolsters. The locking clip 29 is then applied by engaging the same over the upstanding eye portion of the filler plate and seating the ends thereof in the recess 25. As hereinbefore pointed out, the clip thus locks the assembled pin against rotation with respect to the body bolster. When it is desired to separate the bolsters or remove the combined locking and center pin, the clip 29 is first disengaged from the filler member and the recesses 25-25. The entire pin is then rotated about its axis until the head portions of the filler member are alined with the slots 24 of the bolsters. As will be evident. the filler member may then be freely withdrawn upwardly throughthe body bolster, the head portion 28 at the bottom end thereof passing freely through the slots. After the filler member has been removed, either of the sections A may be displaced laterally inwardly until. the opposite end portions of'the flanges, which form the top and bottom heads, are in alinement with the slots, whereupon the section may be withdrawn either through the body or truck bolster, the heads passing through the slotted portions of the bolsters. The other section A may then be displaced laterally and removed in a similar manner. a

From the preceding description taken in connection with the drawings, it will be evilent that I have provided an exceedingly rugged center pin of the sectional type wherein completeannular head members are provided at opposite ends to assure shouldered engagement with the retaining shoulders of the bolsters at all times and thereby providing maximum tensile strength in all relative angular positions of the body and truck bolsters.

A decided advantage is also obtained by locking he assembled pin against rotation with respect to one of the bolsters in that all danger of the pin shifting to a position where the head memoers of the filler member will become disengaged is avoided.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.
