The invention relates to foary coupling mechanism employed for 'the purpose of connectingran automaticr Coupler of the vertiele cated yin which the clearances between the` parts are amply sufficient to prevent breakage or injury of the mechanism during buffing operations.
A primary feature of the invention, gener-v ally stated7 consists in employing, a forward.
ly curved loop member Vfor connectinga dra'whook to a coupler of the typel employing al rotatable knuckle, the loop member being pivotally mounted on the' coupler .headand -being connected toa link device adapted to cooperate with a drawhook and the coupler head having a bollard forengaging the loop member to prevent forward rotation 'of the latter under the influence of draft forces applied to the mechanism. f
vA further feature of the invention consists in pivoting a loop member'upon the guard arm side of-the couplerheadl and in providing` the coupler head on its knuckle side with a bollard for cooperating` with the loop member to-prevent for-wardrotation of the'latter. i
A still further feat-ure of the invention.
consists in'undercutting ltlierear face of the bollard which cooperates .with the'pivoted loop member, whereby accidental upward movement of the loop'membe'r is prevented when the mechanism is in service.
Other features of the invention relating yto advantageous forms and relationsof parts.
will hereinafter appear.

Figure 4 is a detailedsectional view on the line 4--/l, Figure l. Y
In the prefered embodiment of the invention illustrated in the drawings, l is an auto-I matiecoupler whOsestem-is' attached tothe car by suitabledraft rigging appliances (not shown) in any usual or' desired manner. Ro-
tatably mounted upon the head 2 of the coupler by knuckle'pin 3 in the usual manner is a knuckle 4 having a tail 5. A suitable lock G inovably mounted on the coupler head normally Vprevents outward or uncoupling rO- tation of tlieknuckle bycooperating with the- 'tail 5 of the latter.
, .Pivotally mounted upon they coupler y head 2 is a loop member provide'd with a downwardly extending post Sfoiming "a pivot for said loop membeiz-l3`or receivin'gthe pivot post 8 the "coupler head is provided with a suitablecylindrical recess or opening 9 and to prevent-forward rotation of the'.

the coupler head andto position the`bolla.rd`
on tlieknuckle side of the coupler head imf inediatcly adjacent the knuckle pin 3,- the bollai'd being somewhat in advance vof the pivotal axis of thev loop member.
The loop member 7 is preferably made' of round bar stock. Between vits pivotal-axis pointof engagement A with the bollard 10 i t is curved so as to be spaced forwardly from the buii'ing face ll of the coupler l1ead,fthe center of curvature of said curved portion be'- ing in spaced relation to the longitudinal axis of vthe coupler when the parts arein normal opera-ting relation. By thisk means the draft forcesapplied yto the loop member 7 serve to swing the coupler to one side so as to move the outer end of the knuckle 4 away from the linkdevice by which the loop member is connected to the drawh'ook 120i an adj acent car.
erably conveXly curved rearwardly'so` asto hook around the bollard'lO to some extent. The cooperating face of the bollardis similarly curved and is undercut as indicatedat it overlaps a portion of the loop member 7 the latte'i` is prevented from accidentally moving upward when the mechanism is in service.
The lpivot post 8 of the'loop member is preferably vertical and may advantageously extendvv entirely through the coupler head 2. Itslength is such as to permit'the vertical movemen'tsnecessary to enable the loop meniber to be moved to and from operative position. A cotter 15 passing` through the lower end of the pivot postu8, may be conveniently employed for retaining the loop member 7 inassembled relation to 'the coupler head. -Y
Adjacent the opening 9 for receiving rthe pivot postof the' loop member the coupler head is formed with a depression or notch 1G into. whichy the loep member descends when it is swung around to the guard arm side. ofthe coupler. -By this means the loop 7; and transition coupling devices carried thereby are prevented from accidentally swinging forwardwhen not in use.
'i The loop member 7 is movably attached toa. .plurality of. connected link members, 17 and 18 respectively, the former being adapted to cooperate with a draft hook 12 and the latter preferably being formed as alii. eye-bar connected at its forward end to the link 17 and attached at its rear end to the loopmember.v The openings 19 inthe Iban mayadvantageously be, flared so as to provide forample flexibility of the connections betweenl the parts without undue increasev in the sizeof saidv openings.
When the transition coupling devices are in use the knuckle 4 is prevented from accidentally rotating inwardly to a position in whichV it would interfere with the link mein bers ofthe transition device. An advantageous means which is employed for this purposel may consist of a coil spring 20 which encircles the lower end of the knuckle pin 3, onerend' of said spring extending into a perforated lug 21 at the lower end of the pulling lugs ofthe knuckle 4- and therother' end similarly cooperating with a perforated ,lug 22 on the underside of the coupler head.
Any-` suitable means inay be employed lfor actuating the coupler lock. The means illustlrated in the drawings are those preferably used for actuating thelock when r'the latter` is provided withv a downwardly eX- tending portion or lifter, and' consist of the Well-known; bell crank lever 28 which is at tached by a pivot'Qllfoperfoiated lugs 25 formed on the underside of the couplerhead.
