Patented Sept. 10, ‘1946 UNITED STATES PATENT OFFICE 2,407,449 MINE CAR COUPLER Erskine Ramsay, Birmingham, Ala. Application February 19, 1945, Serial No. 578,683 7 Claims. 1 This application is a continuation in part of my previously ?led application, Serial No. 543, 305, ?led July 3, 1944. This invention relates to automatic couplers, particularly to automatic couplers for mine cars, and has for an object the provision of apparatus of the character designated which shall be adapt ed to conserve space between coupled cars and (Cl. 213—180) 2 showing the relative positions of the couplers when the cars are rounding a sharp curve; Fig. 3 is a partial end view of a car showing the means for holding the coupling members re tracted; and Fig. 4 is a detail view of the coupling members. Referring to the drawing, I show in Fig. 1 cars 5 and 6; The end of the car 5 has a circular thus provide additional loading capacity, which opening 8 therein to which is joined by welding may be easily coupled and uncoupled, and which 10 a spheroidal socket number 9. On the adjacent is simple of design and economical 0f manufac ture. A further object of my invention is to provide an automatic coupler for mine cars which shall be so disposed and constructed as to permit the dumping of one car at a time without uncoupling from other cars. Brie?y, my invention comprises a socket mem~ ber which is mounted in the end of a mine car, end of the car 6 is mounted a draw bar member it which is smaller in diameter than the open ing 8 and which protrudes from the end of the car 6 and is adapted to enter the spheroidal socket 9 on the car 5 to which it is coupled. The center of the socket 9 and the center of the draw bar member II] are both located in the long axes of the cars upon which they are mounted, where by one car of a string of cars may be dumped in in the longitudinal axis thereof, and a draw bar 20 any well known form of rotary dumper without member also mounted in the long axis of the uncoupling from other cars. car at the opposite end thereof, the draw bar As may be seen from a consideration of Fig. 4, member including pivoted, radially extending the draw bar member It! is hollow and has pivot coupling members, or arms, which are adapted to ally mounted thereon coupling members I! and enter and engage the walls of the socket mem I2, each of which is slightly longer than the ra ber. The coupling members are normally held dius of the spheroidal socket 9 whereby, when apart by means of a spring located within the spaced apart, to the position shown in Fig. 1, draw bar member and may be retracted by they engage the walls of the socket member and chains so as to uncouple the car, which chains hold the cars upon which they are mounted cou connect with the coupling members, and extend 30 pled together. As may also be seen from Figs. inwardly of the car upon which the coupler is 1 and 2, the outer end I3 of the draw bar mem mounted and outwardly in position to be engaged ber is solid whereby to limit the outward swing by a workman. Inasmuch as the draw bar mem of the coupling members I! and i 2.

The spring It‘ is around the pin I‘! and is thereby held in place. The arms of the spring extend straight outward ly, as may be seen in Fig. 4 to engage the cou pling members H and I2.
