Abstract: An improvement in devices for the thermostatic control of engine coolant comprises a radiator hose with an internally mounted thermostatic valve. In one embodiment of the improved device, a flexible hose has a radially inwardly projecting annular flange on which the radially outwardly projecting annular flange of a conventional thermostatic valve may seat. In another embodiment, the annular flange of a thermostatic valve is modified to permit it to be clamped onto a coil of a helical spring held coaxially within a flexible radiator hose. The improved thermostatic coolant control devices eliminate the requirement for gaskets, gasket cement, and unbolting and bolting metal parts together heretofore, required for the replacement of thermostats.

Abstract: A gravity positioned detent is moved into obstructing relation to the end of a slidable latch member when the luggage case is wrong-side-up, preventing operation of the latch mechanism and opening of the case. When oriented right-side-up, the detent is moved out of the way, allowing full operation of the latch mechanism and opening of the case.
