RAILWAY DRAFT-RIGGING.

Specification of Letters Patent.

Patented J an. is, 19115.

Application filed March 4, 1914. Serial No. 822,406.

To all 1072 one it may concern Be it known that 1, JOHN F. OCoNNon, a citizen of the United States. residing at Chicago, in the county of Cook and State of Illinois. have invented a certain new and useful Improvement in Railway Draft-Rigging, of which the following is a full, clear, concise, and exact description. reference being had to the accompanving drawings, forming a part of this specification.

My invention relates to improvements in draft rigging for railway cars.

The object of my invention is to provide a strong and etlicient draft rigging for railway cars, and one in which a high spring capacity may be obtained.

In the accompanying drawings forming a part of this specification, Figure 1 is a side elevation of a draft rigging embodying my invention: Fig. 2 is a plan View partly in horizontal section on line 2-2 of Fig. 1, and showing the parts in normal position: Fig. 3 is acrosssection taken on line 33 of Fig. 1; Fig. 4 is a plan View partly in horizontal section, showing the position of the parts with the intermediate spring fully compressed, and the follower springs engaging their respective stop-shoulders in butting movement; Fig. 5 is a plan View partly in horizontal sect on. showing the position of the parts in full buff.

Referring to the drawings, the numerals 66 represent draft-sills or parts of the car-frame to which the draft rigging is applied.

7 represents a tie plate suitably secured to the draft-sills by the bolts 8--8, and adapted to support the draft-gear 9 which is mounted between the draft-sills 6. The draft-gear 9 is inclosed by the draft-yoke 10, which is suitably connected to the drawbar 11, only the rear end of the draw-bar being shown in the drawings.

The numerals 12-12 represent counterpart stop members secured by suitable means, preferably the rivets 13-43, to the draft-sills. The stop members 12 are provided with the front stop-shoulders 1414, the rear stop-shoulders 15-15, the rear intermediate stop-shoulders 16-16, the frontintermediate stop-shoulders 1717, the front spring stop-shoulders 18-18, the rear spring stop-shoulders l919, the rear intermediate spring stop-shoulders 20-20, and the front intermediate spring stopshoulders 2l21.

The draft-gear 9 is preferably of the spring type, and comprises the transverselv hollow front follower 22, the fiat springs therein, the transversely hollow rear follower 2l, and the flat springs 25 therein, and the intermediate spring member 20. The transverse opening 27 in each of the followers is formed between the front wall 28 and the rear wall 29, each of said walls being convex in relation to the flat springs passing through the said opening when the springs are straight and in their normal position as illustrated in Fig. 2 of the drawings. The flat springs in each follower a e preferably composed of a plural tv of flexible tlat steel plates 3030, the front set of springs 23 projecting at its ends bevond the front follower, the ends of said springs being adapted to engage the front spring stops 18 on forward movement of the draw-bar, and the rear intermediate spring stops 21 on rearward movement of the draw-bar. Similarly the rear set of springs 25 proiects at its ends beyond the rear follower 2+. and is adapted to engage the rear spring stopshoulders 19 on rearward movement of the draw-bar. and the rear intermediate spring stopshoulders 20 on forward movement of the draw-bar. The front follower is provided with a preferahlv integral rearwardlv extending boss 31, and the rear follower is provided with a preferablv integral forwardly extending boss 32. the bosses 31 and 32 being suitablv alined and of suitable length to permit their engagement and limit the compress on of the spring member 26. The intermediate spring member 20 preferablv comprises an inner coil 33 and an outer coil 34, the said coils being seated at their ends against the inner faces of the followers. In preferable construction. the flat spring members 23 and 25 in their respective followers are of greater capacity than the spring member 26 seated between the followers. v

In normal position of the parts of the gear, the forward flat springs 23 engage the front spring stops 18, a short space 35, as illustrated in Fig. 2 of the drawings, being maintained between the forward face of the front follower 22 and the front stop-shoulder 14; also in the normal position of the gear, the rear springs 25 are in engagement against the rear spring stop-shoulders 19, there being a slight space 36, as illustrated in Fig. 2 of the drawings, between the rear face of the rear follower 24 and the rear stop-shoulders 15. On rearward movement of the draw-bar, init ally the rear springs 25 remain stationary and substantially in their normal straight position, holding the rear follower 24 as a stop for the intermediate spring member 26, the same being compressed against the rear follower by the rearward movement of the front follower. Upon the engagement of the boss 31 of the front follower with the boss 32 of the rear follower, and the limiting thereby of further compressing movement of the spring member 26, the flat springs 23 in the front follower engage the forward intermediate spring stops 21. At this point in the rearward movement of the front follower a slight space 37 remains between the rear face of the front follower 22 and the rear intermediate stop-shoulders 17, the said space being substantially equal to the space 36 between the rear follower and the rear stopshoulders 15. The position of the parts at this point of the rearward movement is illustrated in Fig. 4: of the drawings. Upon further rearward movement of the drawbar, the springs 23 through the front follower are flexed against the convex forward wall 28 within the follower, and the rear springs 25 are flexed against the convex forward wall 28 of the rear follower 24 until the front follower engages the front intermediate stop-shoulder l7, and the rear follower engages the rear stop-shoulders 1.5, when the buffing movement of the gear will be complete and the parts will be in the position illustrated in Fig. 5 of the drawings.

On forward movement of the draw-bar, the

front flat springs 23 are in engagement against the front spring stop members 18 holding the front follower 22 as a stop against the forward movement of the intermediate spring member 26, there being the space 35 between the front face of the front follower 22 and the front stop-shoulders 14. The intermediate spring member 26 is compressed by the forward movement of the yoke drawing the rear follower 24 forwardly until the boss32 of the rear follower engages the boss 31 of the front follower. Upon such engagementthe rear springs 25 carried within the rear follower 24- engage the rear intermediate spring stop-shoulders 20, at which point in the forward movement of the draft-gear there will be a space between the front face of the rear follower 24v and the rear intermediate stop-shoulder 16 substantially coinciclentin length with the space between the front follower and the front stop-shoulders 14. On further forward movement of the draw-bar, the intermediate spring member 26 moves forwardly without further compression between the followers, and the front flat springs are compressed against the convex rear internal face 29 in the front follower until the front follower engages the front stop-shoulders 14-, and meanwhile the rear springs 25 within the rear follower 24 are flexed against the convex rear face 29 within the rear follower 24 until the rear follower engages the rear intermediate stop members 16, where upon the forward movement of the gear is complete.
