These'v-tie" plates may be secured to 'both the sills and thecast'ings 20 in; any suitable inaunmna Athth'e opposite endsEof-the car, the sills 17 'are-providediwith' trwnsvers'el yialined co'upler' key receiving";

slots -22-i-'22;wliich are reinforced by suiteble cheek plates members-v heavinga, reinforced: flanges extending. into" the slots; As IfIOSl3'-" 'cle arly shown in Figure 5, each :che'ek plate 22 i has transverse, vertical stop shoulden 23 at the inner end thereof, the stop shoulders of each pair of cheek plates forming front stop lugs for the shock absorbing mechanism by which the corresponding coupler is operatively connected to the sills 17. At each end of the car inwardly of the stop lugs 23, the sills 17 are provided with a pair of stop castings 24 which are secured to the webs of the sills by rivets as shown. The castings 24 are preferably of such a length that they bear directly at their inner ends on the outer side of the corresponding filler casting 20. The front end portions of the casting 24 present transverse rear stops for the shock absorbing mechanism. At each end of the car inwardly of the corresponding casting 20, the sills 17 are provided with front and rear follower key receiving slots 26-26 for a purpose hereinafter pointed out.

The underframe structure thus far described is directly connected to the truck bolsters 13 so as to move with the same. At each filler casting 20 I provide a center bearing casting 27 which cooperates with the center bearing portion 15 of the corresponding truck bolster in the usual manner. The casting 27 is secured to the corresponding filler casting 20 in any suitable manner preferably by being riveted thereto.

Any well known type of shock absorbing mechanism may be interposed between the coupler ateach end of the car and the sills 17 and in the present instance a shock absorbing mechanism of the friction type is illustrated.

As shown, each coupler 14 has a yoke member 28 connected thereto, the yoke comprising the usual strap portion within which the shock absorbing mechanism is disposed. As

herein shown, the shock absorbing mechanism includes a friction shell 29 having friction shoes 30-30 and a wedge member 31 cooperating therewith. It will be understood that the arrangement of the friction shock absorbing mechanism is the usual one, in which spring resistance means is disposed within the casing 29 which opposes inward movement of the friction shoes and wedge. As shown, the inner end of the casing 29 cooperates directly with the rear stops 24 and a main follower 32 is interposed between the wedge and the stop lugs 23. The inner end of the corresponding coupler shank bears directly on the main follower 32 and the coupler shank is connected to the yoke by a transverse key 33 of the usual type extending through key slots 34-34'in the side walls of the hood of the yoke. r

The key 33 of each coupler has the opposite ends thereof working in the slots 22-22 at the corresponding ends of the sills 17. The shock absorbing mechanism ust described operates in the usual manner in absorbing the shocks in both bull and draft and reacts between the couplers and the underframe proper of the car which includes the sills 17 25-25 and and the truck bolsters which are fixed thereto.

The superstructure of the car which carries the main body of the same includes a pair of longitudinally disposed spaced sills 35-35 extending from end to end of the car and secured at their opposite ends to the end sills 11. The body bolsters 12 at the opposite ends of the car are also directly secured to the sills 35 as shown in Figures 4 and 5. The sills 35 are spaced such a distance apart as to receive the sills 17 slidably therebetween.

The sills 35 are movably connected to the sills 17 by supporting links 36-36 at each end of the car. Each link 36 has a pivotal connection with the corresponding castings 24 at the same end of the car, the castings 24 being provided with inwardly projecting cylindrical sleeve-like portions 37-37 and the upper ends of the arm of the link 36 being provided with a sleeve-like section through which a connecting pivot pin in the form 0 a relatively heavy stub shaft 38 extends. At the bottom each link is also provided with a sleeve-like section 39 which accommodates a pivot pin in the form of a shaft 40 having its opposite ends journaled, in cylindrical portions 41-41 formed on castings 42-42 sccured to the sills 35. As most clearly shown in Figure 3, the castings 42 are secured to the outer sides of the sills 35 and are slotted. adjacent their lower ends to accommodate the bottom flanges of the sills. As further shown in Figure 3, the bottom edges of the sills 17 are. disposed an appreciable distance above the cylindrical portions 41-41 of the castings 42 and the sleeve-like section 39 of the link 36. The pivot members 40 are held against endwise movement in any suitable manner and as herein shown are provided with cotter pins extending through the opposite ends thereof, washersbeinginterposedbetween the )ins and the outer sides of the castings 42. 1 s will be evident, the superstructure of the car including the sills 35, bolsters 12, side sills 10 and end sills 11 are supported for swinging movement on the underframe structure proper, the superstructure thus hav ing relative movement with respect to the underframe structure proper in a lengthwise direction.

At the opposite ends, the sills 35 are provided with alined slots 43-43 to accommodate the outer ends of the coupler keys 33. Inwardly of the body bolsters at each end of the car the sills 35 are provided with front and rear follower key receiving slots 44 and 45 which are normally in alinement with the corresponding follower key slots 25 and 26 of the sills 17.

The superstructure of the car is yieldingly supported on the underframe structure proper so as to take care of both bufiing and draft shocks. Any suitable cushioning or shock absorbing means may be employed for this nsea zsas keys48+48; The follower keys 48extend through the alined'hey receiving: slots 25 and 44211161526 and 45-of the sills l7 and 35 respectively. As shown,;the :key. receiving slots of the- sills 17 and 35 are of greater length than the width of theakeys so that the: keys, and the followers: mounted: thereon have: movement with respect to' the sills! In the normal position of the parts, the followers and-thelreys 48 .areheldlseparatedby the springs 46 with the front edge of the front follower key 48 engaging the front end walls of the slots and 44 and the rear edge of the rear follower 20 key 48 engaging the rear end walls of-the slots 26 and 45.

In the operation of my improved railway car structure, assuming that a buffing shock is applied to the coupler at the left hand end of the car as shown in Figures 1, 2 and 5, the shock absorbing mechanism 29 will be compressed between the follower 32 and the stops 24. Inasmuch as the trucksare connected to the sills '17, this shock absorbing means will absorb the major portion of the shock. The shocks transmitted to the sills 17 will also be transmitted to the front follower key 48 of the cushioning means immediately in back of the body bolster thereby compressing the spring 46 against the rear follower 47,the

key of which is held against rearward movement with respect to the sills 35 of the superstructure of the car. ment of the sills 17 will also compress the spring shock absorbing means 46at'the other end of the car between the corresponding front and rear followers which cooperate with the follower keys 48 of the sills 17 and 35. As will be evident, the superstructure i and the body of the car will thus be cushioned against shocks independently of the shock ab sorbing means cooperating with the coupler. Due to the compression of the spring shock absorbing means comprising the spring members 46, there will be relative movement be tween the sills 17 and the sills 35 lengthwise of the car. This movement is accommodated by the connecting links 36 which act in the manner of pendulum members to support the superstructure of the car. As will be evident, in addition to the tendency of the sprin s 46 to return the superstructure of the car to normal position with respect to the underframe structure proper, the weight of the car body and the superstructure acting on the pendulum links aids in this returning movement.

Ina draft action, the operation is similar to that just described but the action of the parts will be reversed, that is the coupler will pull the yoke outwardly, compressing the The rearward movefriction shock: absorbingimeanss against-the main follower 32 which reactsragainsttheistop lugs: 23 and the sills: 17, 1' therebytending: to pull the latter. outwardly also and compress= ingthe springs 46 :at bothends-of thecar be tween the followers-47 whiclnare connected to'the sills '17 and 35 by'the:keys;48. v

As will be evident, my" improved cartoonstruction provides 'a :ruggedibackbone 'for' the: car in that the same; is provided'with'longitudinallyextending spaced sillsa which are fixed with respect to the superstructure: and the principal load ofithe" buflingi and draft shocks is carried by thezdraft:sills'whichiare movable with: respect to the superstructure sills and are secured to; the truckf'structureofi the car; Itis further pointed out that by the:
