9- Glaims. (Cl. Z13-60) This invention relates to combined striking castings for railway cars and more particularly to such adapted to receive replaceable carrier blocks.

The principal object, of myV invention, generally considered, is to provide a combined. casting formed with portions serving, respectively, as a coupler stop orv striking casting anda sill tie member or coupler carrier iron andprovidedwith means for connecting. said casting to the associated center sills of a car, said carrierv iron portion being formed to hold a replaceable carrier block and wear plate.

An object of my invention is the provision of a combined striking casting and coupler' carrier member suitable for use withiaswivelfbutt coupler and adapted for supporting either aY swing. or interlocked coupler carrier.

Another, object, of4 my'invention is tor provide a. combined strikingcasting andi sill tie member adapted for receiving a carrier block with depending portions on the base thereof interlock.- ing with the. sill tie member and adaptedV for transverse insertion into place with respect thereto.

A further objectY of my invention isgto provide a carrier block for supporting an associated coupler, whichiblockis notched' on its upper face to receive a removable wear plate.

A still further object of my invention is. to provide a combined striking castingforuse with railway cars which is adapted to receive a carrier block, the end portions ofthe base web of which are elevatedabove the remainingportion thereof and one of said portions is provided with an aperture adaptedtov register with a. corresponding aperture in the supporting portioniof the come bined casting and receive arsecuring pin` An additional object of my invention is to pro,-

videV a combined casting adapted for connectionV with the center sills of a car andrprovidedwith a sill tie portion adapted to support a couplercar.- rier block, the side portions of said` castingbeing apertured for permitting transverse insertion and removal of said blockand the upper portion: of y tion, thescope whereof is defined by the appended claimszv Figure l is an end elevation, partly in transverse section, illustrating an embodiment of'` my combinedistriking castingwith associated carrier blocksupporting the coupler; and

Fig, 2 is a central longitudinal sectional view of the construction shown in Fig. 1, the associated coupler being shown diagrammatically.

Referring to the drawing in detail, like parts being designated by like reference characters,

there is shown a combined casting 1 formed with a coupler striking portion 2, a coupler carrier iron or silltie portion 3, and rearwardly extending ear or web portions 4 preferably lying on the outside of and adjacent to the web portions 5 of the center sill 6 of the car. The web portions 4A are preferably connected tothe adjacent ends ofv the center or draft sills 6 by a plurality of rivets 'I and are also preferably bifurcated or formedas upper and lower sections 8 and 9', respectively, leaving notches 10 therebetween, said notches partially embracing the slots l1 provided in the associated center sills 6 for the reception ofthe usual, form ofv draft key 12. For strengthening u the webs of the sills around said slots l1, cheek plates 13 are provided connected tosaid'webs by 'rivets 14, some of which may also serve for con,- necting the combined casting to said sills. The rearwardly extending web portions etmay also be provided withy outstandinglug portions or anges l5 adapted for connection with the reinforcing angle ironsl.

The striking casting portion 2` of the combined castingk 1 is preferably formedV with upright web -i portion 17 'adapted for engaging with the horn of the coupler. 18 illustrated diagrammatically by dot and dash lines upon sufficient rearward'move'- ment thereof and aA lower inwardly extending web portion 19' overlying the shank of the couipler` 18. y

Extending from the upper edge of the web portion 17 and continued rearwardly toi the end sill 20 is a shelf or web portion 21 which is prefi- .erably provided' at its rear edge with anl upthe upper flanges of the center sill 6 and the front edge of the cover plate 25. The rear edge of the web 19 is preferably reinforced by an upstanding bead or rib 28.

The coupler carrier iron or sill tie portion 3 of the combined casting is preferably formed with a substantially horizontal web portion 29 and upright flanges 30 positioned on opposite sides of said web, said flanges extending both above and below said web and thereby providing a trough 31 in which is received the associated carrier block 32. Said carrier block 32 is inserted in and removed from place through one of the transverse apertures 33 provided in the web portions 4 of the casting and after insertion is prevented froin loss or undesired removal by having depending portions 34 on the base thereof which interlock between elevated end portions 35 of the web 29 of the carrier iron portion.

For locking the carrier block in place an upwardly offset end portion 36 on the base of the carrier block 32 is apertured, as indicated at 37, which aperture registers with a corresponding aperture 38 in the elevated portion 35 of the carrier iron portion, said apertures being adapted to receive a pin 39 headed at its upper end and provided with an aperture 40 adjacent its lower end to receive a cotter or other locking device.

In order to lighten the weight of the carrier block 32, the central portion thereof is reduced in height by elevating the lower outline thereof as indicated at 41 and thereby omitting the base web 34 except adjacent the ends thereof. The supporting web 29 in the combined casting may be depressed or downwardly offset along a corresponding distance as indicated aty 42.

The flanges or webs 30 are preferably rigidified with respect to the web 29 by means of substantially triangular web or gusset portions 43 and at their ends the webs 30 are preferably curved outwardly and upwardly to merge with the side webs 44 ofthe casting which in turn adjacent their upper ends merge with the web 17 forming the striking portion of the casting.

Between the webs 44 are preferably posi-tioned the bearing portions 45 which may be employed for supporting swing carriers for the coupler. In the present instance, however, such swing carrers are not used and the lower webs 46 of said bearing portions 45 define the upper walls of the apertures 33 through which the carrier block 32 is received.

The carrier block 32 is preferably generally box-shaped in cross section with lower webs 34-36, side webs 47 and the upper web 43. The intermediate or central portion of said upper web 48 is depressed or downwardly notched as indicated at 49 between bosses 5D, the upper edges of which extend close to the webs 46 and thereby limitl upward movement thereof in the apertures 33. The ends of the carrier blockbeyond the bosses 50 may be of reduced height as illustrated thereby saving in the weight of the block. IThe depressed portion 49 between the bosses 50 serves for receiving and supporting a wear plate 51, which preferably is inverted U-shaped in cross section and involves an upper web portion 52 and depending flanges 53 on the sides thereof.

In the present embodiment I have shown' a swivel butt coupler 18 associated with my combined casting l and the butt 54 of said coupler is relatively deep and the dimensions of the combined casting aresuch that said butt is insertable when the carrier block 32 is removed. In order therefore to apply the coupler 18 it is necessary to first insert the butt 54 thereof through the aperture 55 in the combined casting l and raise the stem of said coupler to a position above that illustrated in full lines in Fig. 1 whereupon the carrier block and its associated wear plate are insertable through the apertures 33 to the position illustrated. After insertion said block may beloclied in position by means of the pin 39.

The ends of the sills 6 are notched as indicated at 57 to permit application of the combined easting but those portions of the webs 5 of said sills beneath said notched portions are continued outwardly into the aperture 55 in the combined casting to closely approach flanges or rib portions 58 on the combined casting which extend inwardly and are of suicient size, and preferably correspondingly stepped to extend beyond the outline ofthe web 5 and the securing rivets 59 and thereby protect both from injury through engagement of the coupler 18 therewith. Shortly below the level of the securing rivets 59 said flanges are preferably taperedand their depth decreased to approximately the thickness of the webs of the center sills, as shown most clearly in Fig. l'. From there the flanges are continued a short distance and may terminate at approximately the level of the longitudinal center line of the coupler stem or slightly below the same.

From the foregoing disclosure it will be seen that I have devised a combined striking casting and coupler carrier iron which is suitable for receiving a swivel butt coupler and adapted for use with either a swing or an interlocked carrier.

The depending portions provided on the carrier block interlock the same with the coupler carrier or sill tie portion of the casing whereby the locking pin is merely necessary to prevent vertical movement of said block to unlocking position.
