Abstract
A safety cock for positively maintaining a coupled connection between a fluid delivery conduit and a chamber during fluid delivery to the chamber and for permitting the conduit to be uncoupled when fluid delivery is disestablished. The safety cock comprises a block having a valved passageway therethrough. A handle projects from the valve and prevents uncoupling of the fluid delivery conduit when the valve opens the passageway by blocking the conduit removal path, but permits uncoupling when the valve closes the passageway.
