[OM/Q0 KUZAK/ BY ATEF/VEV United States Patent-" CAR COUPLER SUPPOR'E MECHANISM Edward Kozak,Clevelai1d,'Ohio, assignor to National M'allcable and Steel CastingspCompany, Cleveland, Ohio, a corporation of-Ohio Application November 14, 1955, Serial No.1 546,302
6 Claims. (CL 213'61) This invention relatestosupporhmech'anism for car couplers; andtmore particularly to combinedstriking casting and coupler; supporttfrnechanism' that can be converted frornthe rigid :type, :.which.- provides only for horizontal angling of the coup1er,-.to,-the resilient type, which permits both"verticahandhorizontal angling of the coupler.
-While the inventionkis :especially' applicableto the 'A. A. R. (Association ofAmericamRailroads) alternate standard type F interlocking coupler strikingcasting and coupler; support mechanism, itr'mayaalsotbeutilized in other coupler supportmechanismiofzsimilar. construction.
It is recognized,thatan'interlocking type." car coupler issuperior in many wayswto the; non-interlocking type. Accordingly, it is .usu"ally-desirable,- both in: new car construction and in the repairwofiolder cars, toinstall interlocking couplers and-associated resilient coupler support mechanism .whichrasaforesaid :provides for vertical as well as horizontal-1: angling 0f the; coupler. However,
probably because ofatheirzhigher.cost-theinterlocking coupler and associated support mechanism have thus far been applied -to a" relatively smalluportion' of the. cars now in use.
The presentinvention provides'means whereby;a railroad may, with aminimum-of extra zcost prepare old-as well as new cars for;ultimate;use with interlocking-couplers. More specifically,-:it-provides-ia' simple .and inexpensive device to permitreadyconversionofthetype of striking casting intended 'for use with an interlocking coupler to, one which williprovidesa' 'rigidxsuppo'rt for a non-interlocking coupler,= su'ch.as the standard Ecoupler. Thus, the striking 'casting, --intended for eventual use with the interlocking coupler; is=-initiallyconverted in.accordance with the invention for use with theznon-interlocking coupler, afterwhich, by:a comparatively simple-process, the striking casting'maybereconverted for'useawith the interlocking coupler.
Accordingly, the primaryyobject of the invention is to provide means for temporarilyrconvertingi aresilient type coupler carrier mechanism into; a rigid type carriermechanism.
Another object :of' :the invention is; to i provide coupler carrier mechanism-10f the rigidi'support; type :that can be for use with a resilient type couplen supportmechanism to furnish a rigid support for, anassociated nonkinterlocking type coupler.
The foregoing and other objects and advantages will become apparent from the following description taken in conjunction with the accompanying drawings, wherein:
M ce
Fig. l -is asectional side elevational view of the combined striking casting and coupler support mechanism embodying the invention.
Fig. 2 is a front elevational view of the mechanism shown in Fig. l.
Fig. 3 is a side elevational view of the coupler carrier conversion member.
Fig. 4 is a fragmentary: side elevational view showing a modification of the invention.
Referring to the drawings, the invention as shown comprises, in its general arrangement, an alternate standard type F interlocking. coupler striking casting and coupler supportmember 10 on which is detachably mounted a couplercarrier member 12 of the rigid support type, in placeof the usual carrier member which is resilientlysupported. Member 10 is adapted to be suitably secured to the center sills andendsill (not shown) of an associated railway car. The shank of an-associated non-interlocking type car coupleris adapted to rest on carrier 'member' 12 and be rigidly supported thereby. Striking casting and coupler support member 10 comprises a *top wall 16 and depending side walls 18, forming therebetween a coupler shank receiving opening 19. A frontabutment portion 20 extends downwardly from top wall-.16 for engagement with the horn of the associated car coupler in. event excessive bufling loads are applied to the coupler.
It will be, noted that rear wall 24 is higher than front wall 22 and that top surfaces 22a and 24a (Fig.1) of both- walls 22 and 24 have been beveled downwardly and forwardly in the usual manner.
In accordance'with the invention, coupler carrier conversion-member 12 is mounted on top surfaces 22a and 24a of .walls' 22 and 24; and is rigidly attached thereto by Weld means 31.;It will beunderstoorL-of course, that if Member 12 is of inverted U-shaped configuration and comprises substantially horizontal top wall 32 and de- .-pending,forward and rearward walls34- and 36, respectively. Forward wall-34 is of greater vertical dimension than ,rearwalL-36 to compensate for the-lesser height of front wallz22 of support portion 21 and thereby assures that top-wall 32 -will be substantially horizontal.
The front lower edge of forward wall34 of carrier member 12 is beveled along its entire length,-.asat'34uz (Fig. 3),
,and the rear .loweredge of rear-wa1l36is likewise .beveled: as at.'36a, for-a purpose-to be hereinafter set forth. The lateralz-extremities of both front and rear walls ,34,.-and36 {are :also beveled as at 34b ;and 3612, .re-
. spectively. :Asaforesaid, .carrier-member 12 ,is maintamed .in .its.assembled position on striking casting sup- ,port portion 21 by weld means 31.
- interlock'ingtypexcar-coupler. 1; place=anon-interlocking type coupler with aninterlock- .ltwillbe understood that carrier member 12,-when so disposed ion .-the top of thesupport portion-21 ofgthe striking casting, wil uprovide a' rigid supportnfor a non- :When it is desired :to recasting to resiliently support the interlocking type car coupler.
In this connection, it will be seen from Fig. 1 that forward and rearward walls 34 and 36, respectively, of carrier member 12 are so spaced apart as to expose the front and rear portions of the top surfaces 22a and 24a of walls 22 and 24. This smaller width of member 12 in conjunction with the aforementioned beveled portions 34a and 36a on the lower extremities of forward and rearward walls 34 and 36 ensures that the outer edges of support surfaces 22a and 24a on walls 22 and 24 will not be covered with weld material but will be visible to enable accurate removal of the welds when it is desired to reconvert the striking casting and support member from a rigid to a resilient type carrier. Beveled portions 34a, 34b, 36a and 36b also produce a stronger weld to ensure positive attachment of carrier member 12 to support portion 21 of the striking casting. It will be noted that the Welds 31, attaching conversion member 12 to walls 22 and 24 of the mechanism, extend transversely along the entire extent of member 12.
In conjunction with member 12, a transverse bar 42 (Figs. 1 and 2) is welded as at 44 to the underside of downwardly extending abutment portion 20 of top wall 16. Bar 42 limits the vertical extent of the coupler shank opening 19 of the striking casting to that required for a non-interlocking type coupler. When the striking casting and associated coupler support member is reconverted into a resilient type support by removal of the rigid carrier member 12, bar 42 is also removed.
Fig. 4 shows a modification of the invention wherein transversely extending grooves are provided in top surfaces 44 and 46 of front and rear walls 48 and 50 of support portion 21 of the mechanism. This provides a convenient method of receiving the weld material for securing conversion member 12 to support portion 21 and also provides a stronger weld connection between the parts. When it is desired to remove rigid carrier member 12 to reconvert the striking casting to a resilient support type for use with an interlocking type coupler, any weld material remaining on surfaces 44 and 46 can be ground down to restore the normal contour of these surfaces.
From the foregoing description and accompanying drawings, it will be readily understood that the invention provides novel means for easily and inexpensively converting a resilient type coupler carrier mechanism into a rigid support type carrier. When it is desired to reconvert the carrier mechanism back to the resilient support type, it is merely necessary to remove the rigid carrier member of the invention and replace it with the conventional carrier and springs.
The terms and expressions which have been employed are used as terms of description and not of limitation and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
