Abstract: An assemblage for intermittently angularly advancing a rotary grille having a motor-driven spit operatively associated therewith is provided. The assemblage includes an elongated tang supported from a spring clip for lengthwise adjustable positioning of the tang relative to the clip. The spring clip is of a configuration to releasably clampingly engage one end of the aforementioned motor-driven spit for rotation therewith and with the tang extending generally radially of the associated motor-driven spit. The assemblage is supported from the spit adjacent one end thereof over one peripheral portion of the grille and the longitudinal positioning of the tang relative to the clip is such to enable the free end of the tang to project downwardly through an opening of the grille defined between adjacent grille bars or members thereof and to engage one of the grille bars or members each time the free end of the tang swings through it lowermost arc segment as a result of rotation of the spit.

Abstract: A water alarm switch having a water-soluble element arranged abutting a support frame on which an elongated member is slidably mounted. The elongated member is anchored on the water-soluble element and cooperates with a spring arranged abutting the frame for biasing the water-soluble element against the frame and retaining the elongated member in a switch-open position. The dissolving of the water-soluble element due to contact with water, and the like, releases the elongated member and permits same to move under the bias of the spring so as to bring electrically connected contacts affixed to the elongated member into contact with mating contacts affixed to the frame and close both the switch and external alarm circuit connected to the contacts affixed on the frame.
