upon the stationary key 8,'1and p'airiof; spaced apart forwardlyextending j yfarms 18-18 which near their forward ends are" for the passage of the coupler'keyl 9."'The coupler key 9 extends through'the draw-bar 20 (only the rear end thereof ybeing shown in the drawings), and the v`slots 19`inithe arms 18 of the rear followerare` i'rearwardlfr extended to permit the rear-wardftravelofthe key 9 therein without buiiing 'strain-thereon. The rear'follower 17j'comprises`ajver- `tical plate 21 having at eitherlateraledge a .provided with the -transverse'slots 19431-9 which preferably is longitudinally extended' in the plates 22 and the arms`1'8,and'also in -preferable construction fpasses transversely through the plate 21 of the rearfollo'ver, rear end of said slot, tliiou'glith'e vertical plate 21, being inclosedbyfthe 'preferably U-sliaped member 2i, which lpreferably integral with the vertical plates 21A andthe longitudinal plates 22. 'l `1 f The slot 23 in the rear fc'xllowerV 1'7I isloii'gii tudinally extended to'permitthe'forward 1"" travel of the rear followerupon ther key/8 in forward movement of the drawbar. j'

Thefront follower 25 corfnprisesavvertical plate 26 having at either laterall edge ajprefl erably integral longitudinal platey 27'-, each of said plates being rearwafrdlyexten'ded to formA the preferably integral 'follower `arms 28--28- The said arms 28`28aresuiiiciently spaced apart to permit the passagelbetween them of the arms/18-`-18"of the rear follower,

the front follower "being provided ywith'fthe spaced-apart longitudinal slots 29-29,' there being one for thegpassagel ltl,1erethrough' of each arm 18 of the rear follower.: The front follower 25 is also'inrovided"with-'the trans# -ve'rs'e slot v30; 'whioh' preferably formed in theffplates A27 Vandy' thearms 28 Vextended therefrom, and Aabn'veai'id'I below the'fslotfy 30 'the-plate 26 of the front folldwfe'r is pro-vided @fend @Qual-S being preferably ,inte-gremita the other', parts of the"followenftleupper of the front follower, and the lower one surrounding the lower spring seat 34 of the front' follower.

Each spring seat is provided with a rearwardly extended boss 35, the rear end of which is in preferable construction in the same vertical plane as the rear faces 36-36 of the collars of the front follower.

The rear follower 17 is provided, both above and below the transverse slot-23, with a forwardly extended collar 37, the upper collar surrounding an upper spring seat 3S, and

- the lower collar surrounding a lower spring seat 39. The collars 37 are preferably integral with other parts of the rear follower, and are partially formed by the longitudinal plates 22-22..

Bosses 40l0 are forwardly extended from each of the spring'seats 38 and 39 of the rear follower, the front faces` 41 of said bosses being in preferable construction in the same vertical plane as the front faces 42 of the collars of the rear follower.y

An upper set of springs 43 is mounted between the upper spring seats of the front and rear followers, and a lower set of springs la is mounted between the lower spring seats .of the front and rear followers. Each set of springs or compression resisting elements consists preferably of an outer spring l5 and an inner spring 1G nested therein.

An upper bolt 1T passes through the upper bosses of the front and rear followers, having a head 18 engaging against the outer face ofthe rear follower, and a nut 49 engaging againstthe outer face of the front follower.

A lower bolt()v passes through the lower bosses of the front and rear followers, and has a head 51 engaging against the rear follower, and a nut 52 engaging against the front follower.

On rearward movement of the drawbar, the coupler key 9 travels rearwardly in the slots 19 in the arms 18 of the rear follower 1T, the draw-bar forces the front follower rearwardly, the arms thereof sliding rearwardly upon the stationary key 8, lthe slots 30 in the front follower being sufficiently for-- wardly extended to permit this movement until the faces of the collars of the front follower engage the collars of the rear follower, and in preferable construction the bosses of the front follower simultaneously engage the bosses of the rear follower while the front end of the transverse slot 30 of the front follower engages against the front edge of the s'tatii'inary key S, The front follower in this movement also slides rearwardly upon the .forwardly extended arms 18 of the rear follower, 'which pass through the longitudinal slots 29 in the front follower.` and the rear follower is held against rearward movement by the engagement of the. stationary key S against the forward ends of the slot 23 through the rear follower, the rear follower thus stopping the rearward increment of the compression resisting members which are compressed between the two followers. On full compression, the parts are in the relative positions illustrated by Fig. l of the drawings. On forward movement of the draw-bar, the coupler key 9 is engaged against the forward ends of the slots 19 in the arms 18 of the rear follower, the rear follower is drawn forwardly in sliding movement upon the key 8, compressing-the springsr against the front follower, the front follower being held against forward movement by the engagement of the rear edge of the stationary key 8 against the rear ends of the slot 30 lin the front follower, the arms 18 of the rear followerv in this movement sliding forward through the longitudinal slots 29 in the front follower until on full compression of the compression resisting elements between the followers the rear edge of the key 8 engages against"`the`rear ends of the slots 23 in the rear follower, and preferably the collars of the two followers, and the bosses of the two followers simultaneously engage.

l. In a draft rigging for railway cars,

draft members, a stationary key extending e between the draft members, a front follower having rearwardly extending arms slidably engaging the stationary key, a' rear follower siidably engaging the stationary key, a draw-bar, compression resisting elements between the followers, the rear follower having forwardly extending arms passing through the front follower and being slidably connected to the draw-bar, the arms of the rear follower passing between the arms of the front follower.

2. In a draft rigging for railway cars, in combination, draft members, a stationary key extending between said members, front and rear followers slidably mounted upon said stationarlv key, a draw-bar, and compression resisting members, the ,reai'` follower being provided with forwardly extended arms slidably connected to the drawbar, the compression resistino' members being mounted both above anc below the` stationary key and between the followers, the followers being each provided with slots for the passage of the stationary key, and having co-acting oppositely arranged collars. the coi'npression of the compression resisting elements being limited on movement of either follower by the simultaneous engagement of the key against one end of the slot in the moving follower, and the engagement of the colla rs of said follower with the collars of the other follower.

ln a draft rigging of the character described, the combination with draft sills, of a front'follower, a rear follower, cushioning means interposed between said fol said key limiting the forward movement of lowers, the front follower having rearthe front follower and the rearward movelo wardly extended slotted arms and the rear ment of the rear follower. follower having forwardly extended arms 5 adapted to be connected to a draw bar, and JOHN F' OOGNNOR' ,a' Astationary key extending. through said Witnesse slotted arms vof the front follower, said key CARRIE Gi RANZ,

being supported between and by said sills. ARHNE R. ARNOLD.
