Speccaton of Letters Patent.

Application filed August 31, 1911. Serial No. 647,000.

To aZZ whom t may concern.' A

Be it known that I, ViN'roN E. SissoN, a citizen of -the- United States, and a resident of the city of Chicago, in the county of have invented a improvement in Car 'End Framing, of which the following is a'speciiication. A

My invention relates to the end framing of railway cars, and particularly to the arrangement of end-posts, end sill, draft girders, and strikingcasting or buffer to form a simple and strong structure to resist the heavy shocks which these parts have to sustain in service.

My invention'lfurtlierrelates to the man ner of supporting the draw-bar carry-iron so` as to relieve it of undue strain and wear from the constant movement of the drawbar, and to transmit directly to the car framing any shock coming upon this member due to longitudinal movement of the draw-bar, at the same time leaving it free to accommodate itself to the lateral position of the draw-bar.

My invention further relates to the details of construction of car end framing and buffers as more fully appear in the embodiment of my invention illustrated in the accompanying drawings and more vparticularly pointed out in the claims.

No claim is made herein to the centering device for the draw-bar except in so far as the striking casting is modified to coperate with said centering device. The draw-bar centering device is described and claimed in applications Serial lios. 646998 and 646999,

pending concurrentlyr herewith.

ln the drawings, in which like characters are used to designate like parts wherever they occur,-Figure l is a view of a portion of the end framing for a lcar showing the striking-casting and draw-bar carry-iron in elevation; Fig. 2 is a part top plan of the same, partly in section on the line Q-Qof Fig. l; Fig. 3 is a vertical section through the sill showing the striking-casting in end elevation and a portion of the draft girder in side elevation; vand Fig. 4 is a vertical section on the line 4:4 of lFig. l, showing a portion of a draft girder and end posts.

Referring to the drawings, there is illustrated a portion of the end of a car showing the end sill l bridging the ends of the longitudinal side sills (not shown) and draft' cured to the girders 3, and riveted to the latter. The end sill projects above the ends of the draft girders, and an angle 2 is positioned adjacent the top flange of the sill on its back face with one leg resting on the draft girders, and riv; eted to both and to the striking-castingll. The lower ends of the end posts l5 rest upon the' horizontal web of the angle, and are seend sill by rivets passing through the flange, angle, end sill and striking-casting, as shown in'Figs. 3 and 4. The draft girders are deeper than the end sill, and are notched out at 5 to take the end sill,

` and also provided with flanges e and 7 on their ends to which are riveted the end sill and striking-casting, respectively.

The striking-casting lc-is formed with a`- sill and riveted therethe flange 8 fitting the end to, some of the rivets going through flanges 6 of the draft girders and some serv-V ing to secure the lower ends of the end posts as well. A projection 9 'is formedy on the striking-casting to back up the draw-bar head and to take any shocks of collision. This projection or bumper is slightly con- Vex in plan, the radius of curvature of the outer surface being the approximate distance to the point at which the draw-bar is pivoted to the car, so that for all positions of the draw-bar there will be the same distance between the rear side of the draw-bar head striking horn and the adjacent portion of the striking-casting. On both sides of this portion 9 there extend hollow arms l0 which are recessed in their top faces and hifurcated to provide bearings for the trun nions 11 of links l2; These links are em braced between the front and rear walls of the arms 10, and are pivotally connected to the draw-bar carry-iron 13 to support the latter. The arms 10 project downward on both sides of the draw-bar and the lower edges next the draw-bar are notched at 14. to form guides for the ends of the carryiron. By this arrangement the drawbar and carry-iron can swing laterally on the links, but any thrust on the carry-iron along the axis of the car will be resisted by the notched Vlower edges of the hollow arms, thus relieving the links of burling shocks.- The rear walls of these arms. 10 are directly riveted to the ends of the draft girders, so as to form a ver rigid support for the endurance of shocks coming on these arms. The front walls of these arms 10 serve as a `protection to`the links rectly to the latter, which must ultimately bear them, without putting undue strain on.

the end sill., and these parts can be made strong enough to take the strain without injury and without adding unnecessary Weight. Moreover, in-case of collision, the .damage to the car from'lading in thefcar shift-ing andknockingfout the` end wall is greatly nected by web lessened, as the arrangement of end posts and end sill is such as. to transfer .thefbrunt of the blow from within directly tothe striking-casting Without any possibility of tearing loose the end posts Aor end sill.

It is evident that other forms and shapes of posts, sills, and striking-castings may be usedl than those illustrated' in' the accompanying drawings without departing from my novel arrangement, and I do not wish to llimit myself to the shapes `of parts herein shown, but

What I desire to-claim is as follows:

1. In a car end framing, end sills and draft girders, and a striking-castin comprising a bumper having an upwar ly eX- tending flange portion adapted to be secured to the sill, and two depending arms offset from the ends of said bumper and arranged at the extremities of the draft girders and rigidly secured thereto, said arms being provided with inside and outside walls conportions terminating at their lower ends in bifurcations, and said striking-casting being formed with pivot bearings spaced laterally from both ends of said bumper above said bifurcations.

2. In a car end framing comprising end sills, end posts and draft girders, a striking-casting having a liange portion rigidly l the end ,secured to the rsill and end posts, two depending arms arranged at either extremity of said striking-casting and provided with web portions rigidly secured to the ends ofv the draft girders, said arms terminating in bifurcations between Vwhich the carry-iron for the drawbar may be positioned, and an integral connection between said arms and flange porttisn substantially in line with pos i copies of this patent may be obtained for ve cents each, by Washington, D. 0.

ing angelportion adapted to be secured to the car, two, depending hollow arms arrangedat each extremity of said bumper,

the yinner walls of said arms'being adapted to be secured to the ends of the draft girders of the car, each of said arms terminating in bifurcations adapted to receive the ends of a draw-bar carry-iron, and the top walls of said arms being recessed to receive and holdin position supports for the ends of said draw-bar carry-iron. y

4.-. In a car end framing comprising draft i sills, a metal end sill, and a striking-casting secured thereto, end posts terminating below the top of said end sill and su ported on a Bange secured thereto, said end) posts being secured to said striking-casting and to said fiange, and said strikin -casting being directly vsecuredl to said draft sills, whereby a rigid .connection between said parts is secured. l

5. In a -car end framing comprising a metal end sill, and a striking-casting secured thereto, end posts terminating below the top' of said end sill, said end posts being secured to said striking-casting whereby a rigid' connection between said parts is secure 6. In acar end framing," in combinationl an end sill secured with a striking-casting,

to said striking-casting, end postssupported on said end sill, and securing means for said end posts passing through said strikingcasting. 4

7. In a car end framing, in combination with draft girders and a striking casting rigidly secured thereto, an end sill having a vertical web secured to. said striking casting, a anged member'having a vertical flange secured to said end sill and a horizontal flange secured to said draft' irders, end posts supported on said flange member, and securing means for said end posts passing through said striking casting.
