ATTORNEY United States Patent U CARRIER FOR RAILWAY COUPLERS Carl D. McClurg, Columbus, Ohio, assignor to The Buckeye Steel Castings Company, Columbus, Ohio STRIKERAND The present invention relates to support means for railway couplers and pertains to improvements in the bearing engagement of a carrier assembly on the striker whereby the entire carrier unit may move laterally relative to the fixed portions of a draft rigging.

An object of the invention is to provide rotatable members between means providing support for the stem of a railway coupler and the striker so that the carrier means for the coupler will be supported by the rotatable members during lateral shifting of the coupler to minimize wear of the carrier parts in service.

Another object of the invention is to provide means for producing a limited lifting of the carrier unit'when it is displaced generally horizontally from a central orneutral position whereby the load imposed on the carrier assembly by the coupler and its stem tends to return the carrier unit to the central or neutral position.

A still further object of the invention is to provide a spring supported carrier iron with means for holding it in assembled relationship with aspring abutment member so that the springs and the carrier iron and the abutment member may be assembled as a unit and thereafter mounted within a pocket at a forward lower portion of the striker without the necessity of employing auxiliary retaining devices. I I

Other objects and features of the invention will' be more apparent to those skilled in the art as the present disclosure proceeds and upon consideration of the accompanying drawings and the following detailed description wherein an exemplary. embodiment of the invention is disclosed. p p

The coupler carrier has particular utility for resiliently supporting the stem of an interlocking type coupler or thestriker of a draft rigging so that the coupler draw bar may angle vertically and horizontally. The striker cast- 2,893,572 Patented July 7, 1959 Ice ing is shown at 16 and is provided with draft lugs 17. The striker casting is provided with a front opening 18 through which the stem 19 of a coupler is adapted to extend. The transverse dimensions of the coupler stem are outlined in phantom lines in Fig. 1 and the coupler shank is adapted to rest on and be supported by a carrier member or iron 21. The carrier iron 21 is resiliently supported with respect ot the striker as hereinafter described and the coupler stem 19 is adapted to angle horizontally within the confines of the opening 18 and at the same time is resiliently supported by the carrier member 21 throughout such horizontal movements. The coupler stem 19 is also adapted to angle vertically and is supported by the carrier member during such movements.

The striker casting 16 except for the front and lower portions may be of a conventional construction which includes webs forming side walls 22 and 23 joined by a top wall 24. The front drag lugs 17 are integral with a rear portion of the side wall structure and the draft lugs may also be of a conventional design and construction. The striker is provided with holes 26 in the side walls for securing the striker to the vertical portions of the sill structure (not shown). The top of the striker casting may be attached in a conventional manner to the top portion of the body sills.

A trough structure is provided at a front and lower portion of the striker 16 which includes a front wall 27 and a rear wall 28. The upper edge of the front wall 27 is in the same horizontal plane as the top edge of the rear wall 28. The lower centralportion of the trough structure is closed by means of a plate or bottom wall 31 while the side portions of the trough structure are open as indicated at 32. In the vicinity of the top of the pocket webs 34 join the front and the rear walls 27 and 28 of the trough structure. The open areas 32 permit the escape of water and debris such as cinders or the like. Open areas 33 are provided at the sides of the striker above the webs 34. The front wall 27 is provided with relatively large weight reducing openings 36.

The upper surface of the plate or bottom wall 31 is provided with a plurality of concave surfaces 37 and in the embodiment illustrated three of such arcuate recesses are provided for receiving rollers 38. The curvature of the concave surface 37 is generated about horizontal axes each having a materially larger radius than that of a roller 38 as will be apparent from a consideration of Fig. 1. A slot 39 is provided in the front wall 27 adjacent the forward end of each roller 38 and a similar .slot 41 is provided in the rear 'wall 28 of the trough structure adjacent the rear end of each roller 38. These slots permit water and the like to escape from the trough and also provide for inspection of the rollers 38. The slots 39 and 41 are of limited size to prevent endwise escape of the rollers 38. A pair of spaced lugs 42 extend upwardly from the \bottom wall 31 at each side of the trough structure and one set of these lugs is shown in Fig. 4. The purpose of the lugs 42 will be more apparent as the disclosure proceeds. i

The carrier iron 21 includes a top plate 43 having a plane upper surface. A log 44 extends upwardly from each end of the plate 43. These lugs 44 are adapted to be engaged by opposite sides of the coupler stem 19 and it will be observed from a consideration of Fig. 1 that the transverse space between the lugs 44 is only slightly \greater than the horizontal dimensions of the coupler stem. Accordingly any horizontal angling of the coupler will cause the carrier iron to move transversely of the .a normal position asshown in Fig. l.-"

The carrier member 21 is provided with a dependent front wall 46 as shown in Figs. 2 and 6. End walls 47 extend downwardly from the top plate 43 and join opposite ends of the front wall 46. A vertical rib 48 is formed along the outside of each end wall 47 and extends to the lower end of each end wall. Each rib 48 is arranged along the rear edge of the associated end wall 47. A hook 51 having a plane surface 52 is formed integral with a lower end of each rib 48. The surface 52 slopes and is inclined downwardly and rearward from the nose of the book. A generally rectangular shaped opening 53 is provided in each end wall 47 adjacent the surface 52 so as to facilitate cleaning of these surfaces during manufacture of the casting.

A depending rib -4 extends transversely along a rear edge of the plate '43 of the carrier iron and an under surface of the rib is inclined slightly as will be apparent from a consideration of Fig. 2. This rib is for the purpose of engaging the top edge of the rear wall 28 of the trough structure at the same time that the forward portion of the top plate 43 engages the top edge of the front wall 27. Such a structural arrangement provides for the support of the carrier iron 21 on both walls of the trough during extreme drooping of the coupler stem. A plurality of spring positioning lugs 56 extend downwardly from an under surface of the plate 43.

The carried unit includes a spring abutment member 58 which is so constructed as to be mounted in the lower portion of the trough of the striker casting and this member is more clearly shown in Figs. 7 to 9. The spring abutment member 58 includes a bottom plate 61 carrying a plurality of upwardly projecting spring positioning lugs 62. The spring abutment member is provided with a pair of upstanding end walls 63. On the inner surface.

of each end wall 63 along a front edge thereof a vertical rib 64 is provided. Each of the ribs 64 terminates at its upper end in a hook 66 having a plane downwardly facing surface 67 (Fig. 9) which is inclined upwardly and forwardly of the carrier assembly. An opening 68 is provided in each end wall 63 adjacent the inclined surface 67 of the hook to facilitate cleaning of this surface during the manufacture of the casting.

Along its front edge the plate 61 is provided with a vertical upstanding rib 69 which extends thereacross and joins the end walls 63. Each end wall 63 and the hook portion 66 is provided with a forwardly facing surface 71 substantially in vertical alignment with the outer surface of the rib 69. The surfaces 71 and the forward face of the rib 69 all serve in cooperation with the inner surface of the front wall 27 of the striker trough to guide the spring abutment member during lateral movements thereof with respect to the striker. The rear edge of the plate 61 and the rear edges of the end walls 63 serve in cooperation with the inner face of the rear wall 28 to further guide the spring abutment member within the trough of the striker.

The under surface of the plate 61 is formed with a series of spaced concave surfaces 72 as shown in Figs. 1, 8 and 10. The concave surfaces 72 are adapted to normally overlie the similarly spaced concave surface 37. The rollers 38 are of such diameters as to support the spring abutment member 58 so as to clear the bottom wall of the trough and these rollers serve to support the spring abutment in a manner as illustrated in Fig. l. The rollers permit the spring abutment member 58 to move laterally with respect to the striker casting. At each end of the plate 61 of the spring abutment member a centrally located lug 74 is provided which in the assembled position is located between the spaced lugs 42 on the bottom wall of the striker pocket. The lugs 74 cooperate with the lugs 42 to position the spring abutment member 58 in a proper position within the trough of the striker and also serve to prevent displacement of the rollers 38 in case of an extreme uplift of one end of the spring abutment member relative to the striker.

A plurality of springs 76 support the carrier iron 21 on the spring abutment member 58 and thus resiliently support the coupler stem 19 -on the striker 16. One of the advantages of the unique structure of the carrier iron 21 and the spring abutment member 58 is that the carrier parts may be assembled to provide a unit before it is mounted in the trough of the striker and without the use of any auxiliary retaining device such as rivets, bolts or the like. The spring 76 are first placed in position with their lower ends over the spring positioning lugs 62 of the spring abutment member 58. The carrier iron 21 is then moved into a position over the upper ends of the springs 76. The side walls 47 of the carrier member 'are then located in positions inside the side walls 63 of the spring abutment member 58. A force may then be applied to one or both of the members to compress the springs 76 and to bring about relative movement of the two members toward each other. The hook shaped portions 51 on the carrier member 21 and the hook shaped ends 66 on the spring abutment member slide by each other on the inclined surfaces 77 and 78 and the surfaces 52 and 67 are brought into position facing each other with the surfaces 52 below the surfaces 67. The force employed to compress the springs 76 is then released and the surfaces 52 and 67 engage each other to maintain the elements as an assembled unit with a predetermined compression of the springs 76.

The rollers 38 are arranged in position on the concave surfaces 37. The carrier unit maintained in assembled relationship by means of the hooks 51 and 66 may then be mounted in the trough of the striker 16 with the concave surfaces 72 of the spring abutment member 58 in positions over the rollers 38. The carrier member 21 with its top plate 43 then assumes the position as shown in Figs. 1 and 2.

The carrier unit may be maintained in position within the trough by means of a bolt 81 which extends through an opening 82 in the front wall 27 of the striker trough. A nut 84 is applied to the inner end of the bolt 81 which is of such dimension as to form a stop or an abutment adapted to be engaged by the top edge of the rib 69. A shoulder 86 is formed integral with the front wall 27 above the opening 82 which serves the purpose of preventing rotation of the nut 84 during application to the bolt 81 and also functions to transmit any force from the nut to the front wall of the striker casting. The nut 84 in cooperation with the shoulder 86 provides means forming an abutment which may be engaged by the top edge of the rib 69 to restrict upward movement of the spring abutment member in service and thus prevent displacement of the rollers 38.

The assembly as shown in Figs. 1 and 2 is such that horizontal angling movements of the coupler stem 19 will shift the carrier member 21 including the spring abutment member 58 and the springs 76 laterally with respect to the striker. Such lateral movements of the spring abutment member 58 takes place while the unit is supported on the rollers 38. Rolling movement of the rollers 38 on the concave surfaces produces a slight lifting of the carrier unit when it is displaced from its normal or central position. The carrier is thus self-centering since the load imposed on the carrier iron and transmitted to the spring abutment member 58 through the spring 76 tends to cause the rollers 38 to return to the lowermost positions on the concave surfaces. The interengagement of the end walls 47 of the carrier member 21 with the end walls 63 of the spring abutment member provides an arrangement wherein the spring abutment member 58 is forced to move laterally with such movements of the carrier member 21.

While the invention has been described with regard to specific structural features of various elements and with regard to a specific organization it will be appreciated and others may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
