13 Claims.

This application is a continuation in part of my application Serial No. 326,133, Afiled December 14, 1928 for .draft rigging.

This invention relates to combined striking castings and, more particularly, to one having .la resiliently supported wear block, or blocks, for permitting vertical movement .of an associated coupler.

The principal object of :my invention, lgenerally considered, is to provide a combined striking casting and coupler carrier member suitable for use with a swivel butt vcoupler .and adapted to resiliently support bottom, l.or top and bottom, wear blocks or members of such a size that,

upon removal, the butt of a swivel butt coupler may be readily applied or withdrawn.

Another object of my invention is to provide a combined striking `casting and coupler carrier member suitable for use with la swivel butt coupler and adapted to resiliently support top and bottom blocks preferably simultaneously retained by .common .fastenings and of such a -size that, upon removal, the butt of a vswivel butt vcoupler may be readily inserted or withdrawn.

A further object of ymy invention :is the provision of .a combined striking casting and coupler carrier or sill itie member comprising a coupler supporting or wearV block resiliently mounted above the ,carrier member, .one side of saidcasting being apertured for endwise insertion of said block, said aperture being normally -closed by a vertically slidable retainer held in locking 4position by gravity.

Other objects and -arilvantagesof the invention relating to the particular arrangement and construction of the various Aparts will become apparent as the description proceeds.

Referring to the Adrawings illustrating my invention, the scope whereof is deiined .by the appended claims Fignre l is a .front elevation showing, partly in vertical section, .one embodiment of my combined casting with ,resiliently supported carrier and striking blocks, the stem of the associated .coupler being diagrammatically illustrated in dot-and-.dash lines.

Figure 2 is acentral longitudinal sectional view oi the combined casting and .blocks illustrated in Figure l.

Figure v3 is Aa View corresponding to ,Figure .1, but showing a modification.

Figure 4 is a side elevational view fof the lemlbodiment vof 'my invention illustrated in Figure 3.

F'gure 5 is :a horizontal Asectional view `on the line -5--5 of Figure 3, looking in the .direction of the arrows.

Figure 6 is a fragmentary perspective view .of the coupler carrier or wear block used in connection with the embodiment shown in Figures 3, 4 and 5.

Referring tothe drawings in detail, like parts being designated by like reference characters, and rst considering the embodiment of my invention illustrated in .Figures 1 and 2, there ,is shown a combined .striking casting and sill tie member l with a coupler striking or stopportion 2, a lcoupler .carrier iron or sill tie portion 43, and vertical side or yconnecting portions 4. Said iside portions are preferably formed with rearwardly extending ear or web portions 5 adapted for connection to the associated center or :draftsills -L(not shown.) Said web portions are Epreferably bifurcated or formed with upper `and lower sections 6 and l, respectively, leaving notches 8 therebetween, said notches normally registering with corresponding slots in the associated sills for the reception of the 'usual Vform of draft key 9 for supporting and connecting an associated ycoupler or drawbar IJ to a yoke Il. For strengthen-ing the webs of the sills around the slots therein rearwardly of the sections `6 and 1, partial cheek plates (not shown) may be provided to supplement said sections which zform, in effect, the

forward portions of cheek plates.

The striking portion 2 is 'preferably formed with a. rearwardly extending web or 'flange AI2 adapted for connection with the sill cover plate (not shown).. Said web or shelf portion is preferably strengthened by .a depending web or flange .I3 and rearwardly extending tapering webs Aor ribs I4 which gradually vdecrease in depth and merge into the web l2.

'The upper ends of the .side portions 4 are, in the present embodiment, formed with pockets I5 ydefi-ned -by the Auppermost web of Vthestriking portion 2 and the vertical webs l of the `side portions 4 which are :preferably `offset outwardly at said pockets, as illustrated particularly 'in Figure 1 yand horizontal portions or flanges l] extending inwardly `from the webs I6 andthe depending flange or web portion l 3 previously described. 'Normally disposed inthe pockets |55 isa striking or wear block i8, the ends -of kwhich rest -on the horizontal portions l 1, andthe ront'web of `which normally extends slightly beyond the 'front edge `of the .striking portion 2, whereby, on buif, the associated coupler l0 normally engages the wear block I8, which relieves the striking portion 2 of wear.

The pockets I5 are preferably larger in vertical dimension than the Wear block I8, whereby Vertical adjustment and movement'l of said block is permitted, said adjustment being desirably efected by positioning shims or washers above or below said block, as desired. Said wear block I8 is desirably formed box-shaped in section, or as a hol- 10W beam substantially rectangular in cross-section. The upper web of said beam is preferably omitted at the central or intermediate portion thereof, and the lower web correspondingly strengthened, as indicated at 20, and provided with a boss or bosses 2I for receiving and positioning resilient means, such as one or more coil springs 22, which maintain the block I8 in normal position while permitting vertical movement thereof upon corresponding movement of the associated coupler I0.

A similar construction is desirably provided above the sill tie or coupler carrier portion 3, the lower ends of the sides 4 for that purpose being provided with pockets 23 preferably of approximately the same size as the pockets I5 and defined by slightly offset portions of the Webs I6 and overlying horizontal portions 24, extending from said webs, and the upper web 25 of the sill tie portion 3. A lower or carrier wear block 26 has its ends normally received in the pockets 23, and said block, for convenience, is preferably, but not necessarily, constructed of the identical size and shape of the block I8, both of said blocks being preferably retained in position by common fastening or connecting means 2l.

As in connection with the block I8, the pockets 23 are preferably formed larger than the ends of the block 26, and washers 28, or other adjusting means, are desirably provided for regulating the normal height of the carrier block 26. The connecting means in the present embodiment takes the form of vertical pins or rods 2'I received in pockets 29 in the sill tie portion 3 or upper web 25 thereof, registering apertures 30 in the carrier block, 3I in the washers or liners 28, 32 in the portions 24 and II of the sides 4 of said casting, 33 in the wear block I8, 34 in the Washers or liners I9, and 35 in the top of the combined casting or striking portion 2 thereof.

For securely locking the rods or pins 2`I in place, the striking portion 2 of the casting is preferably formed with upstanding collars or bosses 35 around the apertures 35, which are provided with horizontal registering apertures 3'I for receiving cotters or other retaining devices 38, whereby undesired removal or loss of the pins 21 and associated blocks I8 and 26 are prevented. In order to allow for wear, the front webs or flanges 39 of the interchangeable blocks I8 and 26 are preferably made thicker or heavier than the corresponding rear webs or flanges, as illustrated particularly in Figure 2. Although the springs 40 supporting the block 26 are disposed about depending lugs or bosses 4I, as in connection with the block I8, they are desirably made heavier or more springs are used than in connection with said upper block, because, as will be understood, said springs 40 are subjected to greater stress than the springs 22 because they normally serve to support the coupler or drawbar. Said supporting springs 4U are preferably positioned under initial compression which may be secured by the simple expedient of letting the weight of the coupler down on the carrier. The block I8, if it is desired that the springs 22 be under initial compression, would have to be forced into place. It will be understood that I do not wish to be limited to having the top springs 22 under initial compression.

Referring now to the embodiment of my invention illustrated in Figures 3 to 6, inclusive, a construction is there shown involving a combined casting la having a striking portion 2a, a sill tie portion or coupler carrier member 3a, and vertical side or connecting portions 4a. The side portions 4a are preferably formed with rearwardly extending ear or web portions 5a, as in the preceding embodiment. The striking portion 2a is preferably formed with a rearwardly extending web portion I2a, reinforced as in the preceding embodiment. In the present embodiment, the striking portion is formed generally box-shaped in section so as to function without the necessity of a separable and movable striking block, as in the first embodiment.

The sill tie portion or coupler carrier member 3a preferably has an upper web 25a, reinforced by side webs or flanges 4I, and serving for the support of an associated coupler carrier wear block 26a. Said block, in the present embodiment, comprises an upper supporting web 42 and depending side flanges or Webs 43, the end portions of which are joined by lower webs 44 forming a wear block inverted U-shape in section at its center or intermediate portion, and box-shape in section adjacent its end portions.

For resiliently supporting the block 26, two supporting plugs 45 are desirably provided with upper flanges 46 normally resting on the lower webs 44 of the carrier block and with the body portions or downward extensions 4'I passing through apertures 48 in said webs 44 into supporting engagement with the webs 25a of the coupler carrier member 3a. Springs 49 are normally disposed between the tops of said plugs and the bottom face of the upper web 42 of the block, said springs being preferably centered by bosses 50 on said plugs. The desired initial compression of the springs to carry the normal load of the coupler or drawbar Ia, exclusive of any additional vertical load caused by relative coupler movement under pull or buff, is desirably obtained by inserting the springs last, and with the aid of tongs or the like forcing them into the position shown in Figure 3. It will be seen that the construction provides for downward movement of the wear block 42 an amount represented by the extension of the portions 4'I of the plugs beyond the lower webs 44, assuming that the springs will not be compressed solid by such additional compressive movement.

To provide for the insertion and retention of the block 26a in place, one of the side portions 4a of the casting Ia is desirably apertured, as indicated at 5|, to permit endwise insertion of said block, said block, after insertion, being desirably retained in position by means of a locking member or plate 52 desirably slidably mounted in grooves 53 in the sides of the casting Ia and normally resting in locking position on ledges or shoulders 54 on said side 4a of the casting. When in lower or locking position, as shown in Figure 3, said plate or retainer 52 lies close to the adjacent end of the block 26a or an extension 56 thereon, thereby retaining said block in place and limiting lateral movement thereof, as will be understood. It will be seen that the retainer stays in locked position under the action of gravity and may be readily released by merely raisingby hand, when .the block 26a may be readily .inserted or withdrawn.

From the foregoing description, taken in connection with the accompanying drawings, it will be yseen that I have devised forms of striking castings and sill tie members with a movable block or blocks permitting vertical angling oi an associated coupler or drawbar about a connecting key. The width of the coupler receiving openings 55 and 55a is desirably suicient to allow for the expected horizontal angling of said drawbar or coupler, the movement of the resiliently supported block or blocks being suicient to permit the expected vertical angling.

Although I have shown preferred embodiments of my invention, it will be understood that modications may be made within the spirit and scope of the appended claims.
