Claims priority, application Great Britain June 8, 1953 15 Claims. (Cl. 213-77) This invention relates to automatic car couplers of the rigid-jawed type and more particularly to interlocking and gathering means therefor.

It is a general object of my invention to provide interlocking means on couplers of the rigid-jawed type to prevent telescoping of the associated cars during collisions and den-ailments and to prevent a pulled out coupler from dropping to the road bed and possibly causing a derailment.

Another object of my invention is to provide means for positive and eflicient gathering of couplers of the rigidjawed type under conditions where the couplers are displaced vertically or laterally, or both, relative to one another.

A further object of my invention is to provide interlocking means on rigid-jawed type couplers which will prevent any substantial vertical and lateral movement between coupled couplers, thereby eliminating a major portion of the contour wear that occurs in service on present rigid-jawed type couplers.

A more specific object of my invention is to provide in a coupler of the rigid-jawed type, interlocking and gathering means including a projection which extends forwardly from the front surface of the pulling jaw of the coupler and a complementary aligning wing pocket on the buffing jaw side'of the coupler head for cooperating with a projection on the pulling jaw of a mating coupler.

.A further object of my invention is to provide an interlocking rigid-jawed type coupler which can couple with existing rigid-jawed type couplers.

A still further object of my invention is to provide an interlocking rigid-jawed type coupler which can be used with a transition screw coupling to permit coupling with other types of draw bar systems.

The various features and advantages of the invention will be apparent from the following description taken in conjunction with the drawings in which:

Fig. 1a is a partial vertical sectional view taken along line aa of Fig. 1.

Fig. 2 is a plan view partly in section similar to Fig. 1 but showing the couplers in' pulled position.

Fig. 2b is a partial vertical sectional view taken along line bb of Fig. 2.

Fig. 3 is a plan view of my interlocking coupler coupled with an existing non-interlocking type rigid-jawed coupler, the couplers being shown in bulfed position.

Fig. 4 is a plan view showing the couplers of Fig. 1 angled the maximum amount laterally with respect to each other.

Fig. 5 is a plan view illustrating the angular gathering range of the couplers when they have been displaced to the same side of a longitudinal center line connecting the pivotal centers of the couplers. In this case,.the forwardlend surface of the forwardly extending portion of lc Patented Mar. 4, 1958 the aligning wing of the coupler on the left is shown engaging the front surface of the pulling jaw of the coupler on the right.

Fig. 6 is a plan view illustrating theposition of the couplers relative to one another as they move together for coupling from their position shown in Fig. 5. This "view shows engagement occurring between the opposing buifin jaws of the couplers.

Fig. 7 is a plan view showing the position .of the con plers following that of Fig. 6, the lock of each coupler having been pushed rearwardly into the lock cavity by the bufling jaw of the opposing coupler.

Fig. 8 is a plan view showing the position of the'coupiers following that of Fig. 7., .each buffing jaw -commencing to move into the complementary recess in the pulling jaw of the opposing coupler.

Fig. 9 is a plan view partly in section,.similar to Fig.5- showing the opposing couplers angularly displaced to the same side of a longitudinal center line connecting the pivotal centers of the couplers, but the coupler on the leftbeing displaced .a lesser amount than the corresponding; coupler in Fig. 5. .In this case the pulling jaw .of one coupler is shown in contact with the .front face ofthe gathering wing on the opposing coupler.

Fig. 10 is a plan view showing the couplers angularly displaced to opposite sides of a longitudinal center line. connecting the pivotal centers of the couplers with the pulling jaw projection on each coupler in engagement with the bufiing jaw of the opposing coupler. Thisrepre sents the maximum displaced position of the couplers on opposite sides-of the center line from which coupling is possible.

Fig. 13'is a side elevational view of an interlocking coupler of the type shown in Figs. 1-12.

Referring in particular to'Figs. 1 and 2, couplers A and B are shown in mating engagement and both are of the rigid-jawed type commonly known as the Willison cou-. pler. Bothcouplers are of identical construction, each comprising a head 12 having apulling jaw 14 and a bufling V jaw 16 which are transversely spaced on opposite sides .of the longitudinal center line of the coupler.

which diverge in a direction forwardly of the coupler; The head has the usual recess 18 on its forward side between jaws '14 and 16 to receive jaw 16 of the opposing A longitticoupled position.

From the position shown in Fig. 6, the inclined front surfaces 16a on the bufling jaws I6 permit sliding of the latter relative to one another, thereby allowing each bufiing jaw to slide into recess 18 in the opposing coupler head. In this connection, the coupler locks 20 are forced rearwardly into the lock cavities by the opposing bufiing jaws as seen in Fig. 7.

t will be noted in Fig. 7, that the side wall 51 of pocket 46 on coupler A diverges outwardly a sufficient amount to preclude engagement between this wall and the projection 3% of coupler B as the couplers rotate to the above position; Further movement of the couplers toward one another from the position shown in Fig. 7 causes the bufiing jaws 16 to slide laterally along the inclined complementary surfaces 20a on the locks, there by moving the couplers transversely of one another to the position shown in Fig. '8. In this position the front face of portion 1% of wing 44 of coupler A no longer engages shoulder 43 on the opposing pulling jaw of coupler B but has moved laterally outwardly past shoulder 43, thereby permitting projection 39 on coupler B to enter further into recess 46 on wing 44 of coupler A. Itwill be noted that in the Fig. 8 position, the forwardly extending portion 44b on the aligning wing of coupler B is disposed outwardly of projection30 on coupler A so that upon further longitudinal movement of the couplers toward one another from the Fig. 8 position, the latter projection can enter pocket 46 on coupler B, to complete the coupling operation. It will be observed that outer surface 79 on the butting jaw 16 of each coupler has been.

relieved, as at '72, so that interference between the buffing jaws and the inner tips 73 of the pulling jaws will not occur as the bufiingjaws slide into the recesses 18 in the opposing coupler heads.

Referring to Fig. 9, it will be seen that it is not necessary that projection 44b on the aligning wing 44 engage shoulder 43 on the opposing pulling jaw in order to obtain proper coupling of the couplers. In Fig. 9, coupler A is shown angular-1y displaced from the longitudinal center line XX connecting the pivotal centers 62 and 64 a lesser degree than is shown in Fig. 5., while coupler B is shown displaced about the same amount as is shown in Pig. 5. It will be observed that the projection 39 on coupler B enters pocket 46 on coupler A, but that the end wall 34 of the projection does not engage the opposing side wall 50 of the pocket. Engagement takes place as at M between the outer edge of shoulder 43 on pulling jaw 14 of coupler B and front abutment surface 4-5 on wing 44 of coupler A. It will be noted that point M lies on the side of the longitudinal center line XX'opp'osite to that of jaws 16 of the couplers. It will be undersood that if coupler B is angled horizontally a smaller amount than is shownin Fig. '9 so that the outer edge of shoulder 43 on coupler B initially engages wing 54 of coupler A at some intermediate point along the diagonally forwardly'extending surface 451:, the inclination of the latter will cause relative sliding between this surface andshoulder 43 until the s'houlderengage's coupler A at point M. From the'Fig. 9 position the couplers will pivot toward one another into coupled position in a manner similar to that explained in connectionwith Figs; 5 throughS.

.Fig; 10 illustrates the maximum gathering range of the couplers when the latter are angularly displaced to opposite sides of longitudinal center line XX. Engagement initially takes place between theend walls 34 of projections 3t and the opposing bufiing jaws as at P. The inclination of surfaces 32 on end walls 34 causes relative sliding of each bufling jaw along surface 32 of the opposing projection, whereby the coupler heads are gathered and aligned for coupling. In this connection it will be apparent that after the bufiing jaws have moved 6 transversely past surfaces 32 and onto side walls "40 of projections 3d the sharp inclination of those walls ensures that the couplers will move positively and quickly into aligned position. In addition it will be noted that the engagement which takes place at points P is equi-distant from and on opposite sides of the longitudinal center line XX so that the couplers will be effectively gathered without danger of jackknifing or misalignment occurring: Fig. 11 illustrates the gathering of a substantially hori-' zontally aligned interlocking Willison coupler during the coupling operation with an existing non-interlockingtype I Willison coupler, which is shown laterally displaced to one side of longitudinal center line XX connecting the pivotal centers of the couplers. The bufiing jaw 16 on the interlocking coupler is shown engaging inclined 'sur-' face 14a on the non-interlocking Willison coupler as at point Q while the bufiing jaw 16 of the latter coupler is in engagement with inclined side wall 40, as at R, on projection 30 of the interlocking coupler. It will be clear that the inclined surface 14a and inclined wall 40 will cause the couplers to gather as they slide transversely of one another during the coupling operation.

It will be noted that the points Q and R are disposed on opposite sides of the longitudinal center line X--X so that jackknifing of the couplers will not occur under this condition.

Another important feature of my invention resides in the ability of the couplers to couple when displaced vertically with respect to one another. The couplers A and B shown in Fig. 12, while aligned laterally with respect to one another, are displaced vertically. In Figs. 12a and 12b which are partial sectional views taken on Fig; 12, it will be seen that coupler A is at a higher elevation than coupler B. As the couplers approach for coupling,

engagement occurs at point S (Fig. 12a) between the aligning wing of coupler A and the projection 30 on the pulling jaw of coupler B and simultaneously at point T (Fig. 12b) between the projection 30 on the pulling jaw of coupler A and the aligning wing of coupler B It will be understood that upon further longitudinal movement of the couplers toward one another from the engaged position shown in Fig. 12 toward the coupled position shown in Fig. 1, the sliding engagement between the slop ing surfaces on walls 34 and 36 of projections 30 and the front abutment surfaces 45 on the aligning wings will cause relative vertical movement between the couplers until the projections enter the pockets 46, after which the couplers move to final coupled position.

It will be observed from Figs. 12a and 12b that surface 32 on end wall 34 of each projection 30, which is convexly curved in a vertical direction, makes possible an increased vertical gathering range over that obtainable solely by means of inclined wall 36, since the inclination of the latter surface will cause relative vertical sliding movement between the vertically displaced couplers as they come together for coupling.

It will be noted that engagement between the vertically displaced couplers A and B shown in Fig. 12 occurs at the points S and T which are equi-distant from andspaced on opposite sides of the center line XX. This will prevent jackknifing of the couplers during vertical align: ment. It will be understood that even though the verti cally displaced couplers are so positioned .relative to one another prior to the coupling operation that engagement will occur only at one of the aforementioned points S or. T, as the couplers come together, vertical alignment of the couplers will still occur to permit successful coupling.

As with all other types of interlocking couplers,.it will be understood that couplers to which my inventionlis applied will be connected to the associated car in such a manner as to allow both vertical and horizontal angling thereof.
