A low profile locking mechanism for securing a lever arm of a coupler in a locked position interlocks with the side surface of the lever arm. The locking mechanism is formed from low cost resiliently deformable material that is protected against impact by the lever arm.

Lock for coupling cam arms

An elbow coupler includes a linkage for locking the coupler to an adapter. 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.

Safety coupler locking means

A 'smart vent' valve is mounted on a liquid storage tank employed in the transportation of liquid. The valve prevents overpressurization of the tank due to increases in vapor pressure and prevents discharge of liquid through the valve in response to pressure surges caused by accidental overturning of the tank. A valve member is provided for a vent opening. Sealing engagement is maintained between the valve member and the vent opening during a finite period of valve member travel caused by an increase in pressure within the tank. The rate of valve member travel is limited by hydraulic system in which hydraulic fluid is forced through orifices from one chamber to another. The high levels of pressure surges do not have sufficient duration to displace the valve member a distance sufficient to move it to a position in which the vent opening is unsealed and liquid could escape therefrom.

Smart vent valve for cargo tanks employed in transporting hazardous

A vent valve for a transport tank car is actuated by pressurized air from the tank cars brake system. The valve is opened by this pressurized air to permit flow of air, through a vent passageway, into or out of the tank. A bellows isolates the pressurized air system from the flow of air in the vent passage so that the braking air system will not be adversely affected by vapors from hazard products loaded in the tank.
