Abstract: A latching assembly particularly well suited for being mounted on the outside of an insulated door without having to disturb or reduce the insulating material, and which is concealed from view by a channel-like handle used for opening the door. The latching assembly includes a helical cam that rotates as the handle pivots and further includes a follower that is driven by the helical cam parallel to the axis of rotation. The latch bolt is attached to this follower, whereby pivoting motion of the handle is converted into translational motion of the latch bolt.

Abstract: A box for storing combustible or easily inflammable substances comprising heat-insulated side and bottom walls and a heat-insulated cover pivotally connected to one side wall, means being provided for equilibrating the weight of said cover in the open position thereof, said equilibrating means being connected to said cover by a heat-sensitive coupling, the latter being adapted to disrupt the connection between said equilibrating means and said cover when a predetermined temperature is exceeded so as to cause said cover to be closed by its own weight.
