CAR CONSTRUCTION Filed Jan. 30, 1950 FigZ m Patented July 1, 1930 Eran srA PATENT et STACY B. HASEIiTINE, OF CHICAGO, ILLINOIS, ASSIGNOR TO W., H. MINER, INC., OF CHICAGO, ILLINOIS, A CORPORATION OF IDELAWARE CAR CONSTRUCTION Application filed. January 30, 1930. Serial No. 424,492.

This invention relates to improvements in car construction, and more particularly to combined locking andcenter pin means for connecting the body and truck bolsters of railway cars.

One object of the invention is to provide anexceedingly simple combined locking and center pin construction, of rugged design for connecting the body and truck bolsters of railway cars, wherein the pin member has shouldered engagement at opposite ends with the respective bolsters to prevent separation thereof, the shouldered engagement at one end of the pin being provided by ahead memher on said pin, and the shouldered engagement with the other bolster being provided by a locking key extending through the pin and bearing on a member engaging the retaining shoulder of the corresponding bolster, the key and cooperating bolster being so designed that the key may be readily applied.

A more specific object of the invention is to provide a combined locking and center pin construction of the character indicated in the preceding paragraph, wherein the locking key is associated with the body bolster and is insertible through the top thereof to apply the same in looking engagement with the pin.

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

In the drawing, forming a part of this specification, Figure 1 is a top plan view of a portion of the body bolster of a railway car illustrating my improvements in connection therewith. Figure 2 is a vertical, sectional view, through the body and truck bolsters of a railway car, corresponding substantially 'to the line 22 of Figure 1. And Figure 3 is a vertical, sectional view of the upper part of the central portion of the body bolster illustrated in Figure 2, showing my improvements in connection therewith, the section being in a vertical plane at right angles to the plane of the sectional view in Figure 2.

In said drawings, 10 designates the body bolster and 11 the truck bolster of a railway car. The body bolster is provided with the usual depending bearing pro ection 12,wh1ch cooperates with a bearing seat 13 providedin of the truck bolster and is fixed against rotation with respect thereto. The body and truck bolsters and the bearing block 14 are provided with the usual alined center pin receiving openings 15, 16 and 17 respectively. The opening 17 of the bearing block is surrounded by an upstanding flange member 18 which en-. gages within an opening provided in the bottom of the body bolster.

In carrying out my invention, I provide the body bolster with a relatively large pocket 19 which communicates with the opening 15 thereof. As clearly shown. in F igureyl, the pocket is of. considerably greater diameter than the opening15, thereby providing arela-v tively wide annular retaining shoulder 20 at the inner end of said pocket. At one side the wall of the pocket is cut away as indicated at 21, thereby providing a guide slot which has a curved bottom wall portion, as clearly, shown in. Figure 2.

The truck bolster is also provided with a pocket, indicated by 22, disposed at the outer end of the pin receiving opening 16 of said bolster, the pocket being definedby the vertical connecting spaced webs 2323 of said bolster.

bolster and cooperates with the annular shoulder at the inner end of said pocket toprevent upward displacement ofthe pin'A. Below the pin spaced slightly from the head thereof is a supporting plate or shelf member 26, adapted to support the pin when unlocked from the body bolster. The plate member 26 comprises a horizontal section and down turned end portions 2727 which; are secured to thewebs23 of thebolster 11 by any suitable securing means, rivets being shown in the present instance. At the upper end, the shank of the pin is provided with a transverse key receiving slot 28. As most clearly shown in Figure 2, the slot 28 has a substantially straight bottom end wall 29 and a curved upper end wall 30. The end wall 30 is preferably of convex formation as clearly illustrated in Figure 2.

The locking or retaining key B is preferably in-the form of a relatively heavy platelike member having a concave recess 31 at the upper end thereof which fits the convex hearing wall 30 at the upper end of the key receiving slot 28 of the pin, and a locking proigction 32 at the bottom side thereof. T e key rojects beyond op osite sides of the pin an the filler member is interposed between the bottom of the key and the retaining shoulder 20 of the body bolster. As clearly shown in F res 2 and 3, the filler member C is in the iii-m of a rin surrounding the shank of the in A. In order to finely adjust the spacing tween the head at the bottom end of the in and the cooperating shoulder onthetruc bolster, spacing shims or washers 33 33 may be interposed between the filler block or ring C and the retaining shoulder ofthe body bolster. Adjacent the shank receivi opening, the upper surface of the block 0 is cut away, as indicated at 34, to provide clearance for the locking projection and lower corners of the key member B while the are being assembled. As will be evident; when the parts are in the position shown in Fi re 2, the key B is locked against removai being confined between opposed side wall portions of the pocket and by the projection 32 engaged within the opening of the member C. As will be evident, the ey can be removed only after the pin has been lifted to such an extent that the projection 32 is withdrawn from the opening in the member C and the lower edge portions at opposite sides of the key are disposed at such a height that they will enter the slot 21, the key being swung on the convex face 30.

The key member is preferably provided with an opening 35 in one side thereof within which a tool may be engaged in order to lift the key out of the pocket of the body bolster and remove the same from the slot of the in. p In applying the center pin to the bolsters of "a railway car, the pin member A is passed upwardly through the pocket of the truck bolster, entering the shank within the pin receiving openings of the two bolsters. The

in is then preferably temporaril supported in thepositlon shown in Figure 2 by means of the shelf 26 which is secured to the webs of the truck bolster by rivets. The filler membei' C with the proper number of washers or shims interposed between the same and the shoulder of the body bolster is then placed in position about the shank of the pin memher A. The key B is then applied by insertin the same through the opening 21 in the si e wall of the pocket 20. While the key is being assembled with the pin, the latter is slightly lifted so that the lower edges of the key Wlll pass the outer wall of the opening 21 and the beveled surface 34 of the opening C, the upper end of the pin being provided with a transverse opening 36 for this purpose, any suitable tool being engaged within the openin to raise the pin. In entering the key B in t e slot of the pin, the concave recessed portion at the upper end thereof is engaged with the convex wall at the upper end of the slot of the pin, the key being swung downwardly about the center of the curved surface 31 of the end wall of the slot into a position shown in Figure 2. After the key has been so positioned as to bring the projection 32 thereof in alinement with the opening in the ring C, the pin is permitted to drop so as to rest on the concave seat in the upper edge of key B, the locking projection 32 at this time engagin within the opening of the ring C. As will he evident, the ke is thus held against accidental lateral disp acement. When it is desired to separate the bolsters, the pin is lifted by a tool engaged with the opening 36 at the upper end of the shank thereof and the key swung to the right, as viewed in Figure 2, and withdrawn through the slot or opening 21 of the bolster 10, the key being manipulated by any suitable tool engaged within the opening 35 at the right hand side of said key. When the key has been removed, the pin drops and is supported by the shelf 26 and the body bolster may be lifted from the truck bolster. If it is desired to completely remove the pin, the shelf 26 may be detached and the pin dropped through the opening of the truck bolster.

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

I claim:
