ABSTRACT:
The dashboard of the automobile has an opening through which a tubular casing projects behind the dashboard. On the casing is a bell having a tubular extension telescoped on the casing. The bell, its extension and the casing are clamped to the dashboard. A trigger is pivoted to the tubular extension and has a hammer to strike the bell, a trigger finger projecting into the casing, and a spring to bias the hammer against the bell. Slidably and removably mounted in said casing is a push-pull unit comprising a plug telescoped within a sleeve and adopted to be moved forwardly relative to the sleeve to compress a coil compression spring between the plug and sleeve. The plug carries an element adopted to be heated to glowing condition when the plug is pushed relative to the sleeve and casing to compress said compression spring, as it moves to a position where said element is grippingly engaged by a spring clamp at the end of said casing, and which clamp carries current from the battery when fingers of the clamp grip said element, to thereby heat said element to glowing condition. When said element is sufficiently heated, the spring clamp opens up automatically because the spring fingers of the clamp expand outwardly and release the plug, so that the compression spring between the plug and sleeve retracts the plug relative to the sleeve as it moves to normal condition. As the plug was pushed into heating position it engaged the finger of the trigger and retracted the hammer away from the bell thereby tensioning the trigger spring. When the element is sufficiently heated, the plug is released and moves back and recedes to normal position, thereby allowing the trigger spring to swing the hammer against the bell to strike the bell and make a sound which signals the operator of the automobile to pull out the plug and its sleeve as a unit and light his cigarette. Without such signal, the operator might forget to pull out the push-pull unit and use it.
