6 Claims. (Cl. 213-61) This invention relates to a coupler support for supportingthe shank of a railway car coupler and particularly to a coupler support in the form of a combined striking casting and coupler carrier.

As pointed out in Couch application, Serial No. 487,803, filedFebruary 14, 1955, the probable ultimate supplanting for freight car use of the A.A.R. Standard E Coupler by the Alternate Standard F Coupler has confronted railroads desiring presently to economize by installing E couplers with a potential excessive expense because of the inability of the coupler support for either type of coupler to function effectively as a support for the other. That application is directed to a coupler support adapted by an invertible carrier member to function with either type of coupler. In the instant application, the structure of the conventional coupler support for the F coupler in the main is retained and made adaptable by minor modification to serve as the necessary rigid support for the E coupler, the modification in nowise interfering with convertibility of the support for use with the F coupler.

It is, therefore, the primary object of the present invention to provide an improved coupler support selectively adaptable for use as either a rigid or a resilient support for the shank of an associated coupler, depending on whether the latter is designed for vertical swinging.

Another object of the invention is to provide an improvement in a coupler support of the sort having a striking casting provided with an upwardly opening pocket normally adapted to receive the carrier iron and supporting springs of a resilient coupler carrier and adapted through removably attachable means to hold the carrier iron against vertical movement and in a position rigidly to support the associated coupler at coupling heights.

An additional object of the invention is to provide an improvement in coupler supports of the sort described wherein the normally resiliently-supported carrier iron is rigidly supported by detachable means and locked in position by retaining clips which also serve to limit the upward movement of the carrier iron when the latter is resiliently supported.

A further object of the invention is to provide an improvement in coupler supports of the sort described wherein the detaclhable means by which the normally resilientlysupported carrier iron is adapted for rigid support of a non-vertically swinging coupler, are supported on abutments integral with the striking casting, thus relieving the connection between the detachable means and the striking casting of stress.

Other objects and advantages of the invention will appear hereinafter in the detailed description, be particularly pointed out in the appended claims and be illusstrated in the accompanying drawings, in which:

Figure 1 is a front elevation view of a preferred embodiment of the coupler support of the present invention with portions broken away and shown in vertical section to more clearly illustrate certain of the details of construction, the support in the form shown being adapted for use as a rigid support.

Figure 2 is a vertical section view taken along the lines 22 of Figure 1.

Figure 3 is a plan view of the coupler support of Figure 1 with portions broken away and shown in horizontal section to more clearly illustrate certain of the details of construction.

Figure 4 is a fragmentary front elevational view, sectioned as in Figure 1, showing the support adapted for use as a resilient support, and

Figure 5 is a fragmentary side elevational view of the coupler support of Figure 4.

Referring now in detail to the drawings in which like reference characters designate like parts, the improved coupler support of the present invention is in the form of a combined striking casting and coupler carrier designated generally as 1, the striking casting 2 of which is designed to be fixed, as by bolting or riveting, to either end of the center sills (not shown) or corresponding part of the mnderframe of a railway vehicle.

With certain modifications hereinafter to be described, the striking casting of the illustrated embodiment is similar to that now standardized for use with the Alternate Standard A.A.R. Type F Coupler, being comprised of vertically directed side walls 3 and a connecting, horizontally directed top wall 4, defining therebetween a coupler opening 5. Below the coupler opening 5 and adjacent their forward extremities, the side walls 3 are connected by a pair of longitudinally spaced, upstanding or vertically directed cross ties or webs 6, the latter being joined at their bottom ends by a horizontally directed web 7 and forming with the bottom web and the included po-rtions of the side walls an upwardly opening pocket 8. Adapted to be received or fit in the pocket 8 is a carrier iron or casting 9 having a top wall or web 10 which normally is horizontally directed and from which depend longitudinally spaced front and rear walls 11 joined at either end by transversely spaced end walls 12 also depending from the top wall 10, these several walls together defining a downwardly opening recess or pocket 13.

In accordance with the usual construction, the top Wall 10 of the carrier iron overhangs its several vertical walls and there are outstanding from the lower extremities of the end walls 12 a pair of horizontally directed flanges or feet 14 which with the overhanging ends of the top wall 10 and included portions of the end walls 12, define a pair of recesses 15, each confronting one of the side walls 3 of the striking casting. Normally extending into each of these recesses 15 and with the associated of the bottom flanges 14 serving to limit the upward movement of the carrier iron 9 relative to the striking casting, is a retaining clip or plate 16 which projects through a slot 17 in the adjoining of the side walls 3 and registering with the recess and is separable from or removably attached or secured to an overlying lip or flange 18 integral with and outstanding from a side of the striking casting by suitable means, such as the disclosed rivet 19.

In the conventional combined striking casting and coupler cairier for the Type F coupler, the carrier iron 9 would always be resiliently mounted on coil or like springs 20 contained in the pockets 8 and 13 and acting against the top wall 10 of the carrier iron to urge that member upwardly, the limit of upward movement, as mentioned, being determined by engagement of the pair of retaining clips 16 with the bottom outstanding flanges 14 on the carrier iron. The instant coupler support functions in exactly that manner when serving to resiliently support a Type F or other vertically swinging coupler, the assembly of parts for this purpose being shown in Figures 4 and 5. However, the coupler support is also enabled to serve as a rigid support for a coupler which 3 is not designed to move downwardly or swing vertically, such as the A.A.R. Standard Type E.

In adapting the coupler support of the present invention to serve as a rigid support and yet be readily convertible to a resilient support, there are provided a pair of rigid supporting members or filler blocks 21, each separable from or removably attached or secured, as by a rivet 22, to the inner face 23 of one of the side walls 3, the carrier iron 9 resting on and being supported by the pair of supporting blocks through its outturned feet 14- and the blocks being so positioned vertically of the side walls as to position the top wall of the carrier iron at proper height for maintaining the E or like associated coupler of the non-downward moving type at coupling height. To relieve the rivets 22 of the stress to which they would otherwise be subjected by the vertical load imposed by the coupler, the blocks 21 in turn are supported or rest on abutments, shoulders or shelves 24 integral with and instanding from the inner faces 23 of the side Walls 3 within the pocket 8. In the conventional striking casting for the F coupler, these portions of the side walls are inclined inwardly in a downward direction and are interrupted centrally by openings 25. This construction is duplicated in the preferred embodiment, necessitating the provision for each of the blocks 21 of a pair of the abutments 24, each abutment being disposed at one side of the associated opening 25 and supporting one side of the block. With the confronting faces of the several supporting and supported members planar and horizontally disposed and the blocks 21 of sufficient thickness to inhibit bending between the abutments 24, the vertical load of the associated coupler is distributed over extended areas and downward movement of the carrier iron 9 relative to the striking casting is effectively prevented.

For locking or holding the carrier iron against upward movement relative to the striking casting, use is made of the same retaining clips 16 as are employed to limit upward movement when the carrier iron is resiliently mounted. Due to the greater height required of the carrier iron for an E coupler than for an F coupler, the ends of the retaining clips 16 which project into the recesses in the carrier iron have insets 26 in their normally upwardly facing horizontal faces, the retaining clips with these insets thus accommodating the difference in the required height merely by inversion of the clips and reversal of the faces confronting the outstanding feet 14 of the carrier iron 9.

Locked against vertical movementv relative to the striking casting by the blocks 21 and retaining clips 16 when applied to an E or a like coupler, the carrier iron 9, as the coupler moves under longitudinal forces, can slide horizontally but only within the limited confines of the pocket 8 of the striking casting. When the conversion to an F coupler is to be made, it is only necessary to remove the blocks 21, insert the several supporting springs and invert the retaining clips 16, to provide the usual resilient support, the upper faces 27 of the abutments 24 then being sufficiently spaced below the retaining clips to permit the carrier iron to move downwardly through its full range.

From the above detailed description, it will be apparent that there has been provided an improved coupler support which normally is adapted to serve as a resilient support for a vertically swinging coupler and with a minimum of readily removable parts is readily adapted to serve as a rigid support for a non-downward moving coupler. It should be understood that the described and disclosed embodiments are merely exemplary of the inventions and that all modifications are intended to be included which do not depart from the spirit of the invention or the scope of the appended claims.
