Th ch ek h ck a s r lngi mechfilllsm, the Q plates are provided with angular-1y extended having a supp rting member forthe-coupler flange sections: 2121 at the; forward ends formed as apartof the same, the supportlng thereof, which are riveted to the vertical web member engaging; the coupler shank closely of the :end sill 15. Each cheek plate is extended above and below the slot 20, as clearly shown in Figure 3, the top and bottom portions being provided with key receiving openings 2222 which are reinforced, as shown, the web of the corresponding center sill being provided; with openings adapted to receive the reinforcements about said key receiving openings.
In connection with my improved railway draft rigging, I employ the usual coupler, which is designated by 23. 'The coupler comprises the usual shank portion which is disposed within the opening 16 and a head at the outer end, the head being only partly shown in the drawing. The coupler is connected to a horizontally disposed U-shaped yoke 24 by means of a transverse coupler key 25 extending through an opening in the coupler shank and aligned openings 26-26 in the side members of the yoke. A shock absorbing mechanism of the friction type'is disposed within the yoke, the same comprising the usual friction shell 27, cooperating friction shoes 2828 and wedge member 29. As will be understood, the friction. shell contains the usual shock absorbing springs which oppose inward movement of the shoes. The inner end portion of the shell bears directly on the transverse cross member at the inner end of the yoke. A combined follower and supporting sleeve member 40 accommodates the shank portion of the coupler 23 and also the front ends of the arms of the yoke 24. The sleeve portion of this member is of substantially rectangular cross section and has spaced top and bottom walls 303O extending the entire length of the sleeve, spaced relatively short side walls 31-31 at the forward end of the sleeve, and a transverse vertical rear end wall 32, of relatively great thickness, forming the front or outer follower member cooperating with the friction shock absorbing mechanism. As shown in Figure 2, the Wall 32 is cut away at opposite sides so as to accommodate the side members of the yoke 24:. The front end of the side members of the yoke are spaced such a distance from the inner ends of the side walls 31 of the sleeve so that a certain amount of relative movement is permitted between these parts. As shown, the inner faces of the side walls 31 converge outwardly to correspond with the shape of the shank of the coupler and are spaced therefrom so as to permit a certain amount of lateral swinging movement of the coupler.
The front end of the sleeve terminates closely adjacent the head of the coupler and the bottom wall 30 is provided with an upstanding flange 33 at the forward end there of, on which the coupler shank is supported. The top wall. is provided w"h a similar ue but the latter is spaced from the top face of the coupler shank, as shown in Figure 1. l.ho inner end of the coupler shank bears directly on the follower member 32 and the latter has a wedge block 29 of the friction shock absorbing mechanism bearing thereon.
Outward movement of the front follower 32 is limited by stop means comprising top and bottom fixed keys 3&3-l extending through the sides of the sleeve section and having their opposite ends disposed in the key receiving openings 22 of the cheek plates. The keys may beheld again st removal by any well known means, cotter pins being shown as employed in the present I we The keys 31 are spaced apart such distance as to embrace and guide the inner end of the coupler shank, thereby preventing tilting or rocking movement of the coupler on the porting flange 33. The inner edges of the keys 34: are normally engaged by the follower 32, thus positively limiting the outward movement of the same. The sleeve portion of the combined follower and supporting member f r the coupler shank is directly supported on the wear plate 18 associated with the carry iron 17.
A spring shock absorbing mechanism is in terposed between the shell of the friction shock absorbing means the stop face 14: of the filler casting 12. A
A, shown, the spring shock absorbing mechanism compris s a rear follower block 35 forming a spring cage, the same being provided with top and bottom spring receiving pockets open at the iront end and closed at the rear end by a transverse wall 36. The resilient member of this shock absorbing means preferably comprises upper ar lower spring members 37-37, each 00111131". -ng inner and outer coils. The spring members 37 hear, at their front enes, on a follower block 38 which is transversely recessed on the forward side, as indicated 39, to accommodate the ransverse end member of the yoke 24. The opening 39 is of such a size as to provide clearance between the end face of the cross member of the yoke and the inner wall of the opening, so that the follower 38 bears directly on the rear end wall of the friction shell 27. The follower block 35 is preferably of the 59.213 length as the forwardly extending arms 13 of the filler casting, so that the rearward movement of the follower block 38 will be arrested by engagement with both the block 35 and the front ends of the stop arms 13.
As shown in the drawing, a slight clearance is provided between the front edge of the coupler key and the front wall of the key receiving opening in the coupler shank, and the rear edge of the key is spaced an appreciable distance from the rear end walls of the slots 26 of the yoke arms. It will be evident that the coupler shank is thus displaceable inwardly with respect to the key to a limited extent before the key will be fo' ced rearwardly with the coupler, movement of the coupler inwardly of the yoke being thus perslots in the side arms .of the yoke.
mitted to an extent in excess of the inward movement of the key in the slots 26, thereby the front ends of the yoke arms will be engaged by the side walls of the sleeve member. The friction shell 27 and the follower block or spring cage 35 are supported from the draft or center sills 10 by saddle plates 5959, three such plates being preferably employed, one of the same supporting the member 35 substantially centrally thereof, another supporting the friction shell substantially centrally, and a third supporting the friction shell at the rear end thereof. In this connection, itis pointed out that the inner end of the combined sleeve and follower 40 is supported by the upper key 34, thereby keeping the same in proper horizontal alignment.
The operation of my improved railway draft rigging, during outward or draft movement of the coupler, is as follows: The yoke 24 will be pulled outwardly with the coupler by means of the connecting key 25,thereby compressing the friction shock absorbing mechanism between the inner end of the yoke and the follower member 32 which is held stationary by the keys .34. Compression of the friction shock absorbing mechanism is limited by engagement of the front end'of the shell with the follower 32.
Upon release, the expansive action/of the spring resistance means within the shell will force the friction shoes and wedge block outwardly, thereby restoring the parts to the normal position shown in the drawing. During a buffing action or inwar-dmovement of the coupler, the follower member 32 will be carried inwardly compressing the friction shock absorbing mechanism and at the same time forcing the follower block v38 rearwardly through the medium of the shell 27, thereb com ressin the s rin s 37 a ainst the end 23 Z 3 wall of the follower block 35 which is held stationary by engagement with the combined filler and stop casting 12. Compression of the friction shock absorbing mechanism is limited by engagement of the follower 32 with the front end of the friction shell and compression of the spring shock absorbing mechanism is limited by engagement of the follower block .38 with the front end of the follower block 35 andthe arms .13 of the stop casting". It will be evident that the travel of the coupler during the action last described is greater than the travel of the same during the draft action,--the travel inbulf being equal to the combined compression strokes of the friction and spring shock absorbing mechanisms. Inasmuch as the follower 32 forms a part of the sleeve in which the coupler shank is housed, the coupler and fol lower, together with the sleeve member, will move in unison both during the inward movement of the coupler in bud and the outward movement in release after the bu tling action, with the result that the coupler head will be always spaced the same distance from the front end of the sleeve during said action;
Extension of the coupler with respect to the sleeve occurs only during the draft ac tion of the mechanism and never exceeds the amount of the compression stroke of the fricalignment of the coupler shank with the remaining parts of the.ra1lwaydraft rigging, i",
the front end portion of the shank being supported onthe transverse flange of the sleeve whlle the rear end is guided between the keys 3484l which also act as front stops for the friction shock absorbing mechanism. In addition, the sleeve is supported by the usual carry iron at the forward end and by the up per'key 34 at the rear end.
