15 Claims. (Cl. 213-442) This invention relates to car couplers, and more ment with an improved knuckle according to the particularly to improvements in American Railinvention. way Association standard couplers. In my Figs. 6 and 7 are vertical, sectional views taken, pending application Serial No. 381,180, filed July respectively, on lines 66 and 7-7 of Fig. 5. 26, 1929, there is described a coupler construction Fig. 8 is a longitudinal, vertical section through 60 which embodies improvements over the prior 2. bottom operated coupler embodying the invenstandard D-coupler, and which is now known in tion, showing the lock in locked position and the the art as the American Railway Association E- lock lifter mechanism operated a slight distance coupler.

The part interchangeable. I have found that when ter of gravity of the lock is located rearward of an E-knuckle as shown in said application is the portion thereof in engagement with said proplaced in a D-head there is a tendency, with botjection 4 as a consequence of which the forward tom and rotary lock operating mechanisms, for edge of the lower end of. the lock leg 2 engages the anti-creep device to interfere with the dethe built-out portion 3 of the coupler head as 35 sired unlocking action of the parts, and by my shown in Fig. 8. The lifter member C of the present invention I have provided a construction Sta d rd bottom-Operated uncoupling mediawhich avoids this disadvantage and at the same nism is p ov with a p 6 engaging in t e time enables the E-knuckle to be employed in an usual slot '1 in the lock leg 2 as is well known in improved manner in the standard D-he d i the art. It has been found that when the knuckle 0 lieu of the standard D-knuckle.

I this I find to be caused by the elements pro- 45 I th accompanying drawings: vided for obviating creeping of the lock. In this Fig. 1 is a plan view of an improved coupler connection, as is well understood, the head of knuckle in accordance with the invention, showt e a d p e includes a P ojection 9, ing a D-lock in engagement therewith. which lies in the path of a lug 8 on lifter member Fig. 2 is a side elevation of the knuckle shown C of th un up mechanism w d 50 i i 1, ber Cis in its normal position. When the knuckle Figs. 3 and 4 are enlarged, vertical sections on Of my application above referred 150 is e p y the lines 3-3 and 4'4, respectively, of Fig. 1, in a D-coupler, the lock thereof is supported on parts of the construction being broken away. the projection aforesaid of the knuckle tail, and Fig. 5 is a view similar to Fig. l, but partly upon operation of the member C for raising the 55 broken away and wi an E-10ck in engagelock it was found that the lug 8 was apt to cm gage the projection 9, frequently blocking further operation of said member C and preventing the latter from lifting the lock. I have found that this difliculty may be eliminated in a simple but highly effective manner whereby the knuckle aforesaid may be employed in a D-coupler without interference with the bottom or rotary operated uncoupling mechanism. To this end I cut away part of the upper portion of the lug 4, to provide the surface shown at 10, with the result that the lock is supported from said lug in a lowered position; the slot 7 being thereby so located with respect to the projection 9 that during upward movement of the member C said slot cooperates with the pin 5 to shift the lug 8. clear of said projection. Thus, as shown in Fig. 8, the lifter member C has been raised from normal position; and the slot 7, in cooperation with pin 6, has moved the lug 8 out of the path of projection 9.

The surface 10, formed by cutting away part of the lug 4, is shown particularly in Figs. 1 and 2, and preferably slopes downwardly toward the front of the knuckle. This construction ,of the surface 10 aids in urging the look as a whole forwardly when the same is in locked position, thus tending to maintain the anti-creep projection 8 in operative relation to the lug 9 as long as the element C is in its normal unoperated position. Owing to the narrow forward end of the D-lock, as shown in Fig. 1. this lock does not rest on surface 11 hereafter described.

At opposite ends of the surface 10 are portions 11 and 12 of the lug 4. When the knuckle K1: is employed in an E-coupler, as shown .in Figs. 5, 6 and '7, the lock LE thereof is supported in locked position through the engagement of its upper lateral projection 16 with the surface 15 of said knuckle. At the same time the head 17 of said E-coupler lock takes a bearing upon the above-mentioned surfaces 11 and 12 of the knuckle projection 4. It maybe noted that the aforesaid lower supporting surface or shoulder of the lock of the E-coupler, as shown at 18, Fig. 5, as compared with Fig. 1, extends a greater distance transversely of the lock than does the corresponding surface 4' on the lock of the D- coupler, wherefore said surface of the E-coupler lock is enabled to bear upon the knuckle tail surfaces 11 and. 12.. As best shown in Fig. 6, the surfaces 11 and 12, andthe respective cooperating wider surfaces 18 and 19 on the E-lock may slope downwardly away from the knuckle tail as illustrated in this view. The knuckle tail surface 10 also slopes downwardly away from the knuckle (see Figs. 2-4) as does the cooperating surface 4' of the D-lock. Ashas been above noted, the surface 12, as shown in Fig. 6, is engaged by the E-lock when the latter is mounted on the knuckle tail, and it will likewise be apparent from Fig. 3 that said surface 12 is engaged by and assists in supporting the D-lock when the latter is mounted on said knuckle tail.

It may be noted that the present construction not only obviates in a particularly effective manner the difficulty hereinbefore mentioned inconnection with the cooperation betwen the D-lock and the E-knuckle, but also avoids the necesssity of tampering with. other parts of the construction which are desirable for the proper operation of the coupler. For instance, the supporting under face of the lock, which cooperates with surfaces 13 and 14 on the knuckle tail for tripping of the lock from lock-set and holding it in a position from which it can readily drop to locked position as the knuckle is closed, is not modified; and this action of the device is not interfered with. Moreover, the functioning of the improved knuckle in the E-coupler is not impaired, for, as above noted, the E-lock may -be supported on said knuckle through surfaces 11, 12 and 15 with the same results and advantages as are obtained by the supporting of the E-lock on the knuckle shown in my pending application hereinbefore referred to. When supported on said surfaces 11, 12 and 15, the lock of the E-coupler assumes the position shown in Fig. 1 of said pending application, and Figs. 5, 6 and 7 herein.

In Fig. 9 there is shown a standard rotary operated D-coupler construction. The elements A, K, L and T in this view are the same as those shown in Fig. 8, and the knuckle includes the novel features above described. I have found thatthe same problem is involved in couplers of this character, which have a lock lifter C including an anti-creep projection 8, and that the problem may be solved in the same fashion as above explained; the knuckle supporting lock, through the cut-away portion of the lug 4, so that as the lifter C moves upwardly the projection 8' is shifted out of the path of the anticreep lug 9.

Means for operating the lifter member C or C, to effect raising of the lock and consequent uncoupling is well known in the art and need not be here described.

As best shown in Figs. 10 and 11, when the E-lock LE is employed in combination with a D- knuckle Kn, the p ojection 16 on the lock is adapted, in locked position, to seat on the surface 15 of the D knuckle, the desired engagement between the knuckle and lock being thus provided for. At the same time, the portion 17 on the E-lock does not interfere with the proper operation of the E-lock when employed with a D-knuckle. As pointed out above, the Erknuckle is capable of cooperating both with the D-coupier and lock and with the E-coupler and look so that, in short, the construction of the cooperating supporting surfaces between the lock and the knuckle tail produces the result that either type of knuckle may be interchangeably used in either type of coupler. It will thus be appreciated that through the provision of the knuckle having upper and lower lock-supporting surfaces complemental, respectively, to upper and lower surfaces provided on the lock shown as above and below the locking face of the lock, the improved knuckle is adapted to support either the improved lock or the D-type lock, while on the other hand, the improved lock is adapted to be supported on either the improved knuckle or the D-type knuckle. This application is a continuation in part of my application Serial No. 381,180 hereinbefore mentioned.
