n but showing the application of a bottom-op-y verating lever for liiting thelockf y 1 'rlvrly'invention relates to car couplers'of the Master VCar Builders type, and particularly lto car couplers of that type in whichV a spring is employed'tof'actuate orY throw Vthe-knuckle.` InA my improved vconstruction pthe knuckle Vand 91 also employ a'lock having improved locking,V lock-setting and lanti-creep f means. My invention also comprises the various rea-- tures'which I shallrhereinafter describe and claim.- y 'f" Referring to the drawings, A indicates a coupler-h'ead51B the knuckle, C the lock,' and` D 'the lifter.V

The-knuckle B is pivoted to the couplerhead inftheusualinanner by the pivot pin 2 and has to the rear of the pivot pinhole/arc shaped pulling lugs 3 on ytopandbottom of the knuckle tail which engage corresponding pulling 'bearings' 4 on the top and bottom walls of the coupler cavity. The knuckle tail adjacent its locking face 5 hasv fa bevelledV portion which inclines yupwardly into a 4o raised transversely vextending portionv or hump '7,y the'purp'ose of which is tofbey later described.

Then knuckle horizontally about, and to the rear of, the pivot pin hole,"which is entered at 9 from the outer side of the knuckle. Seated in the cavity' 8'is a springl() which at its inner endy bears *against an abutment 11v and at Vits outer end about acentering projection 12 on f 'the spring carrier 13;` The carrier 13 has a` central aperture through its hub 14 for the pivot pin,' a rsurface l'whichY bears against B has a cavity 8 extending-- the innerfiace of-the 'side' `wall 1670ilv the" Vcoupler head'. The carrier also has la lug17- Y which comes 'vinto bearing vwith the interior j Yweb or,wa1l .18 inside ofgthe'knuckle taiL Y 5 vertical'sectionf on the lline* 2--2ot` Fig;` 1; y .l

end against the""abutinent 111. The 'spring carrier :13 is then passedthrough the open` ing 9 in'such manner that the'k outer end'of the spring lies between 'thecentering-projec#Y` tion 12 andthe hub 14 of thecarrierl. As

soon asthe surface V19 has passed inside the hump 21 onthe wall `20offthe'knuckle the l 4 I A f lcarrier'is rotated in a counter-clockwise dithrowing means is contained in the knuckle rection until the lug 17 s'swung aroundintoV contact with thev web 18. The spring lOis then compressed and snapped over` the -proje'ction` 12' and willthen 'comeinto bearing". with the lshoulder 22on the projection1,12,

closing movements of the knucklethe spring by eliminating 4any substantial bending of the spring 10,' l

' When the spring and spring carrier have .l

been assembled in the knuckle-as just -de-A scribed they are automatically locked in place-by the Abearing of the 'lug 17 against the web 18 of the knuckle tail and lby the curved surface 19 against thewall V2O, and

these parts are heldl in such position bythe pressure of the spring-10,which is under a substantial initial Acompression.` The carrier lis thus held firmly in jplace so that if desired the knuckle,' with spring 10` and carrier 13 in position'therein; can be handledY vand shipped as a singlepiece.`

The lock C is comprisedV 'of a locking head 23 with a. depending leg12landLa` forwardly projecting foot 25 and a lock-setting shoulder i 26 'at the heel Vofthe foot. Between 'thehead' '23, and the foot 25`is a transversely extending recess 2T through which the knuckle tail swingsl in opening and closingV and engages the under side `of the head(A 23 ofthe erslltype having a rotative knuckle and a vertically movable lock, spring mechanism for actuating the knuckle vcomprising a spring carrier and. a spring, the spring be ofv movementV relative thereto, the carrier having fulcrum bearing on the couplerhead whereby the compression ofthe sprin 10 forces the knucklel into' open position, an retaining means forspring and carrier.
