The linkage has a resilient, laterally deflectable link that limits the forces applied to the linkage thereby preventing the components of the linkage from being overstressed. A spring loaded, blocking sleeve prevents the coupler from normally remaining upright on an adapter, unless it is locked thereon through use of the locking linkage. A flapper valve is interconnected with the blocking sleeve to the end that the valve is normally closed and then opened when the coupler is locked onto an adapter.

The fluid connector (40) includes a seal (62) which is forced into a bore (70) of a piston (66) having a smaller diameter than the seal, so that the seal (62) is radially squeezed to seal the external surface of the fluid conductor (61). A collet assembly (50) of the fluid connector (61) is forced to reduce the diameter to grip the external surface of the fluid conductor (61). A spring (68) which is disposed in the piston (66) compensates seal preload mechanism for variations in fluid conductor size.

Abstract: Male fluid couplers (14) are attached to a control valve (94) mounted in a holder (96). Female fluid couplers (16) have their sleeve members (72) held in an aperture (108) in a sleeve member retainer (110) by snap rings (112). Lever arms (122 and 124) are attached to the sleeve member retainer (110) by pins (126 and 128). Pins (134 and 135) on the lever arms enter slots (136) in the male holder (96). Movement of the lever arms (122 and 124) moves the female couplers (16) into engagement with the male fluid couplers and allows locking balls (40) to move into locking ball grooves (38). Upon release of the handle (130), the spring (80) moves the sleeve member (72) in a position locking balls (40) in the grooves (38). Movement of the handle (130) in the opposite direction moves the sleeve members (72) into position to release the balls (40) from the grooves (38). Continued movement of the handle (130) moves the female couplers (16) from engagement with the male couplers (14).

An interior surface of the first end defines a cone frustrum cooperable with the dockside pump cone frustrum fitting, and the exterior surface of the first end is a cylindrical surface with a semi-toroidal recess at a central axial portion, which recess cooperates with the curved surfaces of the locking cams. The second end of the adaptor has external threads that fit one of three common sizes of boat deck fitting internal threads (e.g.

Abstract: An unloading valve for hopper cars used for transporting dry fluent material such as carbon black. An unloading pipe extends outwardly from the bottom of the hopper, and a closure removably attaches at the end of the pipe. The closure includes a plug extending within the pipe and presenting a surface that confronts the dry fluent material adjacent the inner end of the pipe. This surface has an angle selected to cause fluent material loaded into the hopper to become packed at the inner end of the pipe during loading and subsequent shipment of the hopper car. When the closure is removed for attaching an unloading conduit to the pipe, the packed material at the inner end of the pipe prevents any of that material from leaking out the pipe before the unloading conduit can be connected.

Abstract: A quick connect/disconnect coupling comprises locking levers. Pull rings facilitate pivoting of the locking levels to a release position. The pull rings are resiliently mounted on the levers in positions that prevent the pulls rings from interfering with movement of the locking levers to their locking positions.

Abstract: A coupler has a locking mechanism which comprises a J-shaped blocking pin which is attached to a housing. A spring urges the blocking pin towards a locking arm so that a pin end traps the arm between the housing and the pin end to hold the arm in a locked position. The spring may be manually compressed to cause the pin end to move away from the arm so that the arm can swing outward to an unlocked position. The protruding pin end is bevelled and the locking arm has a bevelled portion which mates with the bevelled pin end. As the locking arm is swung to its locked position, the blocking pin end is pushed away from the arm allowing the arm to pass freely by the pin end. After the locking arm has passed over the pin end, the pin end is drawn toward the arm by the spring capturing the arm in the locked position.
