To all whom it may concern:

Be it known that l, DONALD Bannows, a

citizen of the United States, residing at larly to a combined stop and tie casting de-' signed for coiiperation with that type of draft rigging in which the coupler and yoke, or other suitable cushion connecting means, is slidably connected'so as to permit the coupler to move rearwardly independently of the said yoke, the combined back stop and tie casting acting to prevent the yoke and cushioning means from moving rearwardly and to distribute to the car sills the loads placed upon the cushioning means in bufling or inward movement of the coupler.

The principal object of my invention is to provide a combined back stop and tie casting for use with draft rigging of the type above set forth, and in combination with a car underframe having. a pair of spaced sills and in which the center line of draft is below the center line of the said sills. To this end the main featurmof my invention, broadly stated, comprises, a combined stop and tie casting in which the bufling face of the stop casting is reinforced by a trans versely extending web which forms, in conjunction with the bufling face and another web of the casting, -an I-beam section adjacent' the central portion of the casting, this section changing to a channel-shaped section adjacent the side flanges or sill adjacent faces of the casting, to allow the insertion and driving of the attaching rivets above the said transverselyextending web, in combination with means to adequately strengthen the casting as a whole against lateral or longitudinal buckling without making the same unduly heavy or large.

There are other features of the invention, as will appear from a more detailed description thereof when taken in connection with the accompanying drawings which are chosen for the purpose of illustrating one embodiment of the invention, and in which: Figure l is a top plan view partially in speclflcatidn or Letters Patent.

F g. 2 is a central longitudinal vertical sect on of the structure shown in Fig. l,

F1g. 3 is a bottom plan view of the combined stop and tie casting,

h1gs. 4 and 5 are front and rear elevatrons, respect1vely,of the combined stop and he casting, and

Fig. 6 is a transverse vertical section'taken on line 6-6 of Fig. 1, looking in the direction indicated by the arrow, the adjacent sills being shown in dotted l1nes.

Throughout the specification and drawings like parts are designated by like reference characters. I a "The draft sills 1 are riveted to the outer faces of the center sills 2 by the rivets 3, r is the rear end of the draft yoke, 5 the cushion ing means, 5 the rear supporting strap therefor, and 6 the rear follower.

The comblned stop and tie casting 7 preferably comprises a pair of spaced longitudi nally extending webs or flanges 8, the outer faces of which are adaptedto contact with the minor or adjacent faces of the center sills 2, the flanges 8 each being connected to the web of the adjacent sill 2 by means of the rivets 9 and 10. The webs or flanges 8 are each preferably formed with an extension 8 extending upwardly above the mainbody of the stop casting, these webs also extend somewhat in rear of the main body of the casting 7, as shown at 8". These extensions of the securing flanges 8 provide suflicient space for the employment of the required number of rivets to adequately secure the stop casting to the car sill without weakening the casting by unduly extending the same. The rivets 10 may, and preferably do, extend through the draft sills 1 in addition to the center sills 2. The flanges 8 are, as shown, suitably connected by a web 11, integrally connected to the lower portions of the said flanges: this webll, adjacent the sides thereof, conforms to the inclination of the lower flanges 12 of the center sills 2, as shown at 13, and may be, and preferably is, connected to these flanges by means of the rivets 14..

Intermediate the ortions 13, the web 11 is, for a portion 0 its length, arched upwardly, as at 15, whereby the central ortion of the said web is brought into a inement with the horizontal and longitudinal axes of the draft rigging, and the casting as a whole is greatly strengthenedagamst longitudinal buckling.

'lhc buffing face 16 of the comblned stop and tie casting is formed by a web 17 WhlCll is preferably connected at the sldes to the side walls or webs 8 by the inclined webs 18. These webs 17 and- 18 form, as clearly seen from the drawings, a truncated wedge or pyramid. The webs 17 and 18 are integrally connected to the bottom web 11, and are further braced and strengthened by a horizontally extending web or flange 19 preferably located intermediate the central portion of the web 11 and the upper edges of the webs 17 and 18.

The combined back stop and tie casting 7 may be, and preferably is, providedwith a centrally located cylindrical opening 20 formed in the bottom web 11, which open ng is adapted to receive the king bolt on whlch the car truck turns or pivots. A collar, or cylindrical. flange, 21, extends upwardly from the opening 20 and forms an extended bearing for the king bolt. A plurality of bracing webs 22, 23 and 24 are provided, the web 22 extending from the collar 21 to the central portion of the web 17 directly bracing and strengthening both of these members. This web 22, as clearly indicated in Fig. 6, preferably extends both above and below the central portion 15 of the web 11, and forms therewith a cross-shaped member designated as 22 The portion of the web 22 below the web 15 is preferably braced by a web or flange 25, which extends downwardly from the central portion 15 of the web 11 intermediate the web 17 and the collar 21. The bracing webs 23 extend from opposite sides of the collar 21 to the adjacent side walls, and preferably e'xtend to the upper edge of the extensions 8*. The web 24, which may be of triangular shape, extends from the collar 21 to the rear portion of the bottom web 11, and is preferably placed diametrically opposite to the web 22.

It will be readily apparent from the disclosure in connection with the foregoing description that the improved form combined back stop and tie casting is adequately braced and reinforced on the center line of draft, and that this bracing does not interfere with the application of suflicient number of rivets to adequately connect the casting to the car sills. In fact, the metal-is so distributed throughout the casting that the casting presents in longitudinal vertical section, adjacent its central portion, the highly desirable I-beam construction, the flanges of said'beam being formed by the web 17,

and portions of the webs 21 and 23, while the web of the beam is formed by the portion 15 of the web 11; the casting also presents in longitudinal vertical section adjacent the side flanges 8, the desirable channel beam formation heretofore referred to, in which i the flanges of the beam are the upwardly 'ing of the rivets which serve to connect the casting to the car sills. It will also be evident that the improved form of combined back stop and tie casting, while possessing great strength and rigidity, is, nevertheless, a simple casting and is, therefore, easy to manufacture, and the casting as a whole is adapted to convey to the center sills the load placed upon the casting by bufiing or inward movement of the coupler.
