Connected to the inner faces or sides of the sill webs 3 are draft lugs formed as an upper casting 22 and a lower casting 23. The upper casting 22 is formed with side webs 24 connected to the webs 3 of the sills, a horizontal transverse web 25 integrally connecting the side webs 24 and extending between the sills and above the associated coupler 1'7, and transverse draft lug portions 26, normally engaged by the front follower 27 of an associated cushioning mechansm 28. Although the cushioning mechanism illustrated is a friction draft gear, it is obvious that I do not wish to be limited to this showing.

At its forward end the web 25 is flanged, as indicated at 29, and connected to the inner face of the end sill 2, whereby said end sill is received between the combined casting 'i and the upper draft lug and tie member 22. The lug portions 26 are desirably braced with respect to the web 25 by upper triangular gusset portions 30 and lower preferably tapering ribs 31 and triangular gusset bracing portions 32 are also desirably provided between the lower ends of the lug portions 26 and the webs 24 of the casting, which are preferably connected to the sill webs 3 by rivets 33. The webs 24 are extended to approximately supplement the rearwardly extending portions 11 on the combined casting 7, as shown most clearly in Figure 3, so that the sills are adequately strengthened, said web portions 24 being on the inside thereof and the web portions 11 on the outside. As in the case of the web portions 11, the edges of the webs 24 arepreferably beaded or ribbed around the slotted portions 15 in the sills, as indicated at 34, thereby increasing the bearing area for the key 16 and forming in effect supplemental cheek plate portions. The lower lug casting 23 is similarly formed in that it comprises a transverse web 35 connecting the lug portions and sills and forming an intermediate sill tie and coupler guiding plate.

The forward edge of said web 35 is preferably flanged downwardly adjacent the sill tie portion 9, as indicated at 36 and the rearward portion is flanged downwardly, as indicated at 37, forming a lug portion for engagement with the front foilower 27. Said lug portion is preferably braced with respect to the web 36 by triangular gussets 38. As with respect to the upper lug portion, the upper edges of the side webs 39 are beaded or ribbed outwardly over the edges of the slotted portions 15 in the sills, as indicated at 40. The upper edges of the lug portions 3'? are preferably strengthened by triangular gusset portions 41 between said lug portions and the webs 39. Below the lower flanges 4 of the sills 1 the web 35 is downwardly offset, as indicated at 42, to directly underlie said flanges for connection therewith by rivets 43. Said offset portions 42 are suitably reinforced by extending the lug web portion 37 outward to the ends of said web portions 42, as indicated most clearly in Figure 4.

The coupler 17 is of the swivel butt type, for example, such as described and claimed in my Patent 1,431,717, dated October 10, 1922. The rear end of the stem proper is therefore formed witha pair of spaced flanges or webs 44 embraced by a swivel block 45 which is formed with flanges or webs 46, which are interspaced so as to lie on opposite sides of the webs 44 and provide bearing pockets 4'? therebetween for engaging correspondingly curved edges 48 on the flanges or webs 44 for swiveling engagement therebetween. The swivel block and coupler stem are connected for pivotal movement therebetween by a vertical pin or pintle 49, which is so positioned that it is cut into by the key 16, as indicated at 50, whereby when the parts are assembled the pin or pintle 49 is retained in proper position by said key.

In order, however, to avoid disarrangement of the parts when the key 16 is not in place, I preferably hold the pin 49 in temporary assembled relation with the swivel block and coupler stein by forming cuts in the ends of said pin, as indicated at 51, and spreading said cuts to form in effect upset ends on said pin and prevent undesired removal or loss in a manner similar to that shown in Figures 4 and 6 of my Patent 1,431,717, previously referred to. The edges of the webs 44 and 46, as well as the corresponding pocket portions, are preferably coaxial with the pin 49 to provide for proper swiveling motion between the parts.

It is well known that a swivel butt coupler of the type described is generally larger in transverse dimensions than a rigid shank coupler and the portion immediately adjacent the swivel block has generally been made larger in such dimensions than the coupler stem between the head of the coupler and the end thereof. Such a construction, while necessitating an increased opening in the striking casting for receiving the swivel block and enlarged butt of the stem, has made it generally desirable or necessary to provide means for closing the opening to some extent after insertion of the swivel block and butt of the coupler, whereby the clearance between the stem and striking casting would not be too great. This has been accomplished, for example, by having removable wear or filler blocks below, above, or below and above said stem which are removed when the coupler butt is being inserted or withdrawn and are held in position in any desired manner when the coupler is in position.

In accordance with my present invention I have enlarged the stem of the coupler between the butt and head thereof so that the vertical and horizontal transverse dimensions are uniform throughout the length of the stem and swivel block whereby upon designing the striking casting for normal clearance with respect to the butt and swivel block said normal clearance is maintained when the coupler is in normal position as indicated, for example, in Figure 1. This result has been accomplished in the present embodi ment by sloping the lower web 52 downwardly and rearwardly, as indicated particularly in Figure 6, to the lowermost portion of the coupler stem, as indicated at 53, where it overlies the sill tie or coupler carrier portion 9 of the striking casting, a wear plate being desirably provided between said coupler and sill tie portion. Rearwardly of the horizontal portion 53 the lower web of the coupler is sloped upwardly, as indicated at'54, to join with the lower curved butt flange or web 44. The upper web 55 of the coupler stem is desirably continued straight forwardly from the offset portion 56 forming a shoulder for engagement with the upper web 46 of the swivel block 45, said portion 55, however, being formed as an upward convolution of reduced width above the stem 17 in the coupler and forming in effect a spacing rib or corrugation for avoiding abnorrnal clearance with respect to the striking portion 8 of the casting 7, and leaving portions of the upper wall on either side, which unite with the side walls, substantially alined with the upper flange 44. The lower outline of the coupler is maintained straight and filled out by ribs or webs 57, the lower edges of which are flush with the lower surface of the web portion 53.

The yoke 18, which is connected to the coupler 1"? by means of the key 16, extends rearwardly around the associated cushioning mechanism 28 and normally abuts the front face 58 of the combined backstop and center filler casting 59. The cushioning mechanism 28 is supported by the carrier iron 60, the ends of which are in turn connected to the outstanding lower flanges 4 of the sills by means of bolts 61 and nuts 62 or any other desired connecting means. Undesired upward movement or displacement of the cushioning mechanism is prevented by an upper tie member 63 connected to the inner surfaces of the sill webs by rivets or the like 64. Therear or U-- shaped portion of the yoke 18 is desirably supported by angular clips 65-, the vertical flanges of which are desirably connected to the sills by countersunk rivets 66 or the like and the horizontal flanges of which underlie the adjacent portions of the yoke. The front portions of the'yoke are not only supported by the key 16 but are held in place by being snugly received between the gusset-s 32 and 41, as shown most clearly in Figure .4.

The backstop 59 has a lower wall or web 67 which is directly supported on the bottom cover plate 6 and connected beneath said cover plate is the center plate or casting 63. The height of the draft gear or cushioning mechanism 28 is so as illustrated particularly in Figure 1. The cen- 35 ter plate 68 is formed, as is usual, with a king pin aperture 70 and the bottom cover plate 6 and the striking casting 59 are formed with registering apertures 71 and '72, respectively serving as continuations of the king pin aperture '70. 40*- In order to strengthen the backstop casting 59, the apertured portion '72 is formed as a hollow cylinder extending the full height of the casting between the lower web or floor 67 and the upper web or top '73, said top '73, however, not being quite as high as the upper edges of the side or connecting walls '74, thereby providing areas above said top for receiving rivets '75 for connecting said casting to the sills of the car. The

upper wall 73 does not extend as far back as the lower wall 67 in the center thereof but the sides are preferably flared outwardly and rearwardly, as indicated at 76, to finally merge into theside walls '74. The front or striking wall 58 of the casting is provided with flaring extensions 77 forming in effect gussets between the extended sides 74 of the casting and the top or roof web 73.

In the present embodiment a plurality of horizontal webs 78 are provided between the top and bottom webs, which webs extend-from the front web'around the hollow cylindrical portion '72 and rearwardly to slightly beyond the rear edge of the bottom web 67, where they are flanged, as indicated at '79. An intermediate vertical web 80 is also provided extending from approximately the center of the striking web 58 to the flanged edges of the webs 78 and tapering from said flanged edges upwardly and downwardly to the rear edges of the webs '73 and 6'7, respectively. For bracing the longitudinally extending webs in- -termediate the ends thereof transverse webs 81 side webs 7d are preferably extended forwardly of the front or buiflng web 58 to provide riveting areas 82.

In the p'resent embodiment the bolster involves pressed plates or transoms 83, the forward one of which has its web preferably in line with the front web-58 of the striking casting and the rear-ward of which has its web preferably in line with the webs 81 of the casting, said front transombeing preferably connected to the casting by common rivets extending through the side extensions 82, the sill webs and the adjacent flanged portions 84 of the transoms. The rear bolster transoms 83 may be connected to the sills and striking casting in a similar manner.

From the foregoing description of my invention, taken in connection with the accompanying drawings, it will be seen that I have provided an improved rigging construction in which front draft lugs are formed as integral ties above and below the draft key receiving slots in the sills. The backstop and center filler casting is of special construction providing for great strength without undue weight and the bottom sill cover plate, which underlies said backstop casting, is coped to permit the employment of a draft gear of maximum height. The coupler desirably employed is of the swivel butt type and the pintle or pivot pin thereof is temporarily retained in position by, in effect upsetting the ends thereof but when in place the lower draft lug cross tie located so as to avoid loss of the pin in any event. The shank of the swivel butt coupler is formed of uniform dimensions throughout to avoid the necessity for filler castings above or below in the striking casting.
