[Class 99 (i).] In an automatic train-pipe coupling, a short tubular connector 13 coupled to the flexible pipe 20 is removably secured to the connector head B through a side opening 22 so that the gasket 15 may be replaced while the connector heads are in contact, and is rotatably mounted by means of a shank 21 having a groove 23 engaged by a projection 24 and a U-shaped spring-pressed locking pin 25. In a modification the shank 35, Fig. 5, of the connector 13 engages in a slot 34 in the head and is retained by a hook 37, the weight of the pipe and the fluid pressure in the pipe, and its end bears against an inclined surface 39. In a further modification the spherical end of the shank 45, Fig. 1, bears against a seat 48 on the end of a screw 47, whereby the pressure in the pipe can be released gradually before the connector 13 is removed. In the form shown in Fig. 9, a member 57 has a stud 56 engaging in a boss 54 of the removable connector 52, a pin 66 engaging a curved slot 67 permitting partial relative rotation. The member 57 is secured in a slot in the connector head B by the locking pin 60. The opening 69 in the connector head is formed with spaced projections to form narrow bearing surfaces for the end of the connector 52 which are flared outwardly at 70. The connector 52 is attached to the pipe 20 by a known type of manual coupling 53 whereby the pipe 20 can be secured to a car not having an automatic coupling. The manual coupling may be of the gravity locking type having a conical gasket 76 provided with a free edge adapted to be drawn on its seat by a vacuum in the pipe.

Couplings, automatic. - A train-pipe coupling D, Fig. 3, capable of limited universal movement is mounted upon a bracket A depending from the usual car coupler and is held in contact with the coupling on the adjacent car by a spring 17. The coupling D is carried by a member E comprising spaced straps 12 arranged on opposite sides of the bracket A and connected at their rear ends by an integral flange 13 which is provided with an opening 13a into which a rearwardly curved portion 10 of the bracket is arranged to project. A tie rod 14 having an elongated slot 15 engages the curved seat 10 formed by the said portion 10 and extends rearwardly through the opening 13 to receive the spring 17. The spring 17 is disposed between an abutment 16'on the tie rod and the flange 13 and presses the latter against lugs 11 on the bracket A when the pipe coupling is free. Fig. 6 shows the disposition of parts when the coupling is mated with another coupling, being free to swing through about 180‹. Specification 19803/10, [Class 99 (i), Pipes and tubes, Joints &c. for], is referred to.

[Classes 21 and 125(iii) ] A closure for petrol &c. drums comprises an inwardly flanged cylindrical sleeve formed about the opening in the drum, an internally threaded bush fitted into the sleeve and having a flange at its top with a concave depression formed therein into which the sleeve flange is forced, the underside of the flange on the bush being formed as an abrupt shoulder beneath which a bead formed on the sleeve interlocks to prevent rotation of the bush, a flanged screwed plug carrying a gasket ring being screwed into the bush so that the gasket seals the joint between the plug, the sleeve and the bush. In the form shown the bush consists of an internally threaded ring A having a flat annular top face 5 between which and the threads 6 a curved bearing surface 7 is formed. The ring is externally flanged, the under shoulder 9 of the flange being formed with a series of arched seats 15. The ring A is pressed into a housing C formed from the material of the drum head B, the housing having initially a downwardly projecting bead 17 and an inwardly projecting dished flange 18 against which the surface 7 engages. To secure the bush the bead 17 is rolled up around the shank 10 of the ring, the metal interlocking with the arched seats 15, so preventing the rotation of the bush. The flange 18 forms a bearing surface for a gasket D carried by the threaded plug E. To prevent undisclosed tampering with the contents of the drum, a thin cap G, removable on destruction, may be crimped over the plug E and housing C.
