Fig. 1 is a vertical longitudinal section of a cou ler embodying m invention with the parts in locked position; ig. 2 is a lan thereof; Fig. 3 is a section similar to i 1 but with the lifter raised to free it from t e anticreep rovisions; Fig. 4 is also a section similar to 1 but with the parts in lock-set position. igs. 5 and 6 are side and rear elevations reipectively, of the upper member of the lifter; 1g. 7 is a section on line 7-7 of Fig. 5; Figs. 8 and 9 are side and rear elevations of the lower member of the lifter; and Figs. 10, 11 and 12 are sections on lines 1010, 11--11 and 12-12 respectively of Fig. 8.

My invention relates to car couplers, and particularly to the standard D-coupler type, and comprises so designin the lifter that it forms a positive lock-toock or anti-creep which I have found to be effective in all conditions of service. The parts of improved lifter are also arranged so as to limit the relative movements t ereof to an operative range. My invention also comprises the features which I shall hereinafter describe and claim.

Referring to the drawings, I have shown my invention applied to a standard D-coupler comprised of the coupler-head A, the knuckle B, the lock C and opener D. The lifter preferably consists of an upper or plug member 2 and a lower or lock engaging member 3. The member 3 has the usual horizontally disposed trunnions 4 which seat in the extensions of the inverted T-slot 5 in the rear upper portion of the lock C. Ofi'set rearwardly and above the trunnions 4, the member 3 has a vertically disposed surface 6 which in all operative positions of the lifter bears against the rear wall 7 of the coupler-head and thereby prevents the trunnions 4 from becoming disengaged from the slot 5 in the lock. The upper end of the member 3 has an elongated slot 8 for the pin 9 by which the members 2 and 3 are connected.

The member 2 has a forked or bifurcated lower end 10 for reception of the upper end of the member 3 between the downwardly extending forks or lugs. The aperture between the forks does not extend as high on the rear side of the member 2 as on the forward side in order to provide a surface 11 against which the upper end of the member 3 will come into contact and thereby limit the rearward movement of the lower member 3 relative to the upper. Also to prevent the member 2 from tipping too far to the rear in lock-set or knuckle thrown ition, the surface 12 on the lower end of t e member 2 is arranged to come into contact with the surface 13 on the member 3. The member 2 at its upper end is provided with the usual uncou ling rod attachment eye 14. To prevent t e upper in reversed position and thereb rendering the lock-to-the-lock inoperative, 0th the top hole 15 and the member 2 in cross section are wedge shaped. Also the rear portion 16 of the member 3 is so thickened adjacent the surface 6 that that portion cannot be inserted into the T-slot 5 of the look. It is therefore apparent the two parts of the lifter can only be assembled in the coupler head and connected to the lock in the correct relation. When the parts of the coupler are in locked position the forward up er portion of the member 3 lies beneath t e top wall 17 of the coupler head forward of the lifter hole 15, as is shown in Fig. 1. If the lock attempts to creep up out of locked position, it will therefore carry the member 3 up against the top wall 17. The member 3 while in locked position cannot move rearwardl so as to clear the wall 17 because any suc rearward movement is prevented by the surface 11 on the upper member 2. As is also shown in Fig. 1, the member 2 when in locked position drops down so that the pin 9 rests in the bottom of the slot 8 and in this osition is not free to rotate in a forward irection about the pin 9 because of the engagement of the surface 11 with the upper end of the member 3, and the member 2 cannot rotate rearwardly relative to the member 3 because of its contact with the rear edge of the top hole 15. It is therefore apparent that the upper member 2 will effectually prevent the lower member 3 from assuming a position in which it would be free to rise through the top hole and thereby permit the lock C to move out of locked position.

member 2 from being inserted When the member 2 i raised by the uncoupling mechanism th. pin 9 slides up in the slot 8 and, as the surface 11 is raised above the upper end of the member 3, the pin will draw the upper end of that member rearwardly from beneath the top wall 17 of the coupler head into a position in ali ment with the top hole as is shown in 3. Then as the member 2 is further lifte the upper portion of the member 3 is drawn throu h the top hole 15 and the lock is raised to loc t osition, as is shown in Fig. 4, or to knuc e thrown position.

M invention is particularly useful with couplers subjected to excessive vibration such as is apt to occur on trains o erated at hi h speeds, or over rough road ds and un er conditions in which the lock lift is apt to be jarred into positions not normally occupied in ordirary service.
